Definitions
- the invention relates to a holding structure for insulating glass panes, in particular for space-forming glazing such as conservatories, pavilions and the like. They are usually made of multiple-pane insulating glass and include a steel construction that is designed as unobtrusively as possible in order to impair the "airy" and light-flooded impression of the glass structure as little as possible.
- the DE 2010 015 999 U1 relates to an arrangement with a roof glazing supported by beams, this and the side walls being made of glass panes and in which the beams are supported by vertical supports.
- the supporting beams each consist of strip-shaped laminated glass plates consisting of several glass panes, with the connection between a support and a beam being made by correspondingly shaped metal parts, which are placed between two glass panes in a section of a glass pane lying between them or by further metal parts between the two glass panes , an insulating glass panel forming the roof glazing and/or a side wall, are attached and glued to them.
- the mechanical connection between two glass plates is created by the relevant metal parts.
- the viability of this arrangement is limited.
- the DE10 2013 217 600 A1 relates to a glass facade with an internal support structure, which comprises at least one support element and at least two glass facade elements, the glass facade elements being connected to the at least one support element on at least one fastening edge.
- the support element has two wings, each of which engages in laterally open intermediate spaces between the glass panes, the support element and the glass facade elements being designed in such a way that the support element is essentially completely surrounded by the glass facade elements in a plane perpendicular to its longitudinal extent. In the absence of anchoring of the support element to a support structure beyond the glass panes, it should only serve to connect the glass panes to one another, but otherwise be largely insignificant in terms of statics.
- the object of the invention is therefore to specify an all-glass construction for conservatories, pavilions or the like made of insulating glass panes which has a high load-bearing capacity and whose steel construction is nevertheless visually as inconspicuous as possible.
- the holding structure comprises a steel profile that can be mounted on an abutment and at least two insulating glass panes with an edge bond at their edges, with a butt joint between the insulating glass panes, with the steel profile acting as an anchor or at least as a partial section of an anchor in the butt joint and parallel to the edges and engages with at least one section in the edge bond of an insulating glass pane and has coupling points for the connection to the abutment, with which it is either flush with the glass panes on the abutment or extends out of the butt joint of the glass panes.
- an anchor In construction, an anchor is a component that, due to its tensile strength, connects different and usually dissimilar components to one another.
- insulating glass panes of a glass front can be anchored to an independent building as an abutment made of steel or reinforced concrete.
- wind pressure and suction forces can act on vertically positioned insulating glass panes, which the anchor must absorb and transfer to the abutment in order to ensure the stability of the glass front of a conservatory, for example.
- the construction according to the invention is therefore based on an abutment such as a building exterior wall or a steel construction, to which it and in particular the steel profile is connected. It therefore does not represent a statically completely independent all-glass construction.
- the individual panes of your multiple-pane insulating glazing consist of individual panes with an edge bond on which the individual panes are glued and sealed together airtight to form an evacuated or gas-filled space between the panes.
- the edge bond primarily forms a narrow end face of an insulating glass pane.
- spacers are glued in between the individual panes in order to ensure not only a defined distance but also a peripheral sealing of the space between the panes.
- Insulating glass panes lying next to one another meet at the butt joints, so that the edge seal of a first insulating glass pane comes to lie parallel next to the edge seal of a second insulating glass pane.
- a butt joint can basically occur between two insulating glass panes that are largely in one plane. In contrast to a scale joint, the insulating glass panes do not overlap at such a joint.
- One Butt joints can also occur between two insulating glass panes that are at an angle to one another. At the corner of a building, the angle is regularly 90°, but can deviate from this both in the direction of higher values and in the opposite direction. According to the invention, the insulating glass panes overlap at one corner only on the front side of one insulating glass pane.
- the steel profile runs essentially in the area of the butt joint, so that it is arranged between the two insulating glass panes of a butt joint and thus runs parallel to the edges of the insulating glass panes.
- This alone allows the steel profile to be arranged in a very unobtrusive manner.
- a section of the steel profile engages in the edge seal of an insulating glass pane in order to hold it from its narrow front side. Unlike gripping around the edge of the insulating glass pane, the engagement of the steel profile in the edge seal represents a quasi "invisible" holding device for the insulating glass pane.
- the steel profile and its section engaging in the edge seal are "hidden" in the butt joint or in the edge seal.
- the invention thus uses the edge seal of the insulating glass pane, which is required anyway, in addition to its attachment to the steel profile. In contrast to a screw connection in the edge seal perpendicular to the plane of the pane, no time-consuming drilling through a glass pane is required. Rather, the invention offers the possibility of both a linear and a punctiform mounting of the insulating glass pane on the edge bond. It can thus be adapted to different loads with little design effort, for example by varying the distances between the sections in the case of a punctiform mounting or by varying the length of the sections in the case of a linear mounting.
- the steel profile according to the invention finally offers cuts or coupling points, usually at its longitudinal ends, with which it connects, for example, flush with the glass panes on the abutment or extends out of the butt joint of the glass panes.
- the steel profile can form a ring beam or at least a section of a ring beam.
- the ring anchor is a ring-shaped, closed component made of steel that prevents the insulated glass panes that have been wrapped around or connected from falling apart by absorbing a thrust that is introduced into the insulating glass panes perpendicular to their plane of extension. If the ring anchor is made up of individual sections, the connections between the sections must be able to absorb sufficient tensile stress.
- the ring anchor can Assemble the steel profile and an abutment to which the steel profile connects.
- the abutment can itself consist of a steel structure or a concrete structure which is steel reinforced. In any case, the abutment complements the steel profile - not necessarily in geometric terms, but at least in static terms - to form a ring.
- the cross-section of the steel profile should be dimensioned as slim as possible.
- the steel profile - especially in the case of an out-of-round ring anchor - cannot be buckling-resistant enough to be able to absorb horizontal forces, especially on longer, flat glass fronts.
- the steel profile can therefore have at least one coupling section for connecting a tension element orthogonal to its direction of extension.
- the tension element can support the steel profile on the abutment or brace it against the abutment.
- the tension element can also provide support or bracing on an opposite steel profile as a section of the same ring anchor.
- the coupling section is not located at the ends of the steel profile, but in its course beyond or outside of its ends in order to support the steel profile in a central area.
- Several coupling sections are also conceivable and useful. Because the use of a tension element shortens a significant free support length of the steel profile and the steel profile can thus absorb greater horizontal loads than its cross section or its area moment of inertia alone would allow, longer facades made of insulating glass panes can be constructed if tension elements are used.
- the steel profile can form a tie rod from an anchor head and an anchor shaft.
- the anchor head is the section of the steel profile that is held in the edge bond of the insulating glass pane.
- the anchor shank is formed by a coupling section of the steel profile running transversely thereto, which enables connection to a tension element.
- the anchor shank thus offers a fastening surface for fastening the tension element, so that it can transfer forces to an abutment orthogonally to the direction in which the steel profile extends.
- the orientation of the anchor shaft itself is of secondary importance as long as the tension element can be attached to it in the force transmission direction of the anchor.
- the section of the steel profile that engages in the edge seal must always be permanently fastened there. It can be wedged, wedged, latched or otherwise in the edge seal to be attached. According to a further advantageous embodiment of the invention, the section of the steel profile is glued in the edge seal. As a result, a sufficiently permanent attachment can be achieved, which can be carried out on site at a reasonable cost without the use of additional construction means and without taking into account narrow tolerances. Silicone adhesives in 2-component technology, for example, are known as suitable adhesives.
- the low demands on tolerances between the sections of the steel profile on the one hand and the edge bond of the insulating glass pane on the other hand enable the components of the holding structure according to the invention to be manufactured at low cost.
- the edge bond has a receiving pocket in which the section of the steel profile is or is glued. It can represent a separate component that is introduced into the edge seal, or it can be formed in the spacer of the edge profile.
- the material of the receiving pocket on the one hand and the material of the section on the steel profile on the other allow the definition of suitable adhesive partners to which the adhesive can be matched.
- the arrangement of the receiving pocket can allow its material to be matched to the adhesive independently of the remaining material of the edge composite.
- the possibly separate receiving pocket can be attached to the edge seal in the factory and thus with high quality, durability and reliability.
- the arrangement of a receiving pocket in the edge bond offers the possibility of defining the dimensions of an adhesive joint between the receiving pocket on the one hand and the section of the steel profile on the other hand, in particular in accordance with the static requirements.
- the same receiving pocket can always be formed or used, which means that the same or repeatable conditions can be achieved when gluing even with different dimensions of insulating glass panes or their edge seal. This means that the bonding can be of high quality, especially if it is done on site.
- a required or desired adhesive thickness can also be set and the adhesive joint can be calculated more reliably.
- the receiving pocket can be designed as a U-profile glued into the edge seal. It thus forms a defined interface in the insulating glass pane for integrating the section of the steel profile, which can be configured linearly or at points or loaded.
- the U-profile can, for example be made of aluminum or plastic, which means that it can be produced with little effort and integrated into the edge seal of the insulating glass pane using known technologies.
- a section of the steel profile is integrated into the insulating glass pane or into its edge seal.
- the section of the steel profile can engage in the edge bond linearly, for example with a profile leg, or selectively.
- the section can be designed as a lug which is formed on the steel profile. It can be welded on separately there or cut out of the steel profile. In this way, it defines a selective fastening of the steel profile, which can have a linear effect due to a large number of brackets lying next to one another.
- a punctiform attachment can be advantageous with regard to the production of the bond, because it can offer shorter adhesive joints, a smaller adhesive surface and thus the advantage of less effort. It can also be structurally sufficient, for example by engaging in the edge seal of an insulating glass pane at only two points.
- the inventive engagement of the steel profile in the edge seal of the insulating glass pane essentially transmits forces in a direction perpendicular to the insulating glass pane held, mostly wind pressure and wind suction forces.
- the steel profile can also be held or fastened in the butt joint between the insulating glass panes.
- the mount can be linear or point-by-point, for example by blocking or gluing.
- a suitable force transmission possibly over the largest possible area, can be achieved, in particular of compressive forces between the insulating glass panes on the one hand and the steel profile on the other.
- the bracket can lead to a low surface pressure in the area of the edge bond of the insulating glass panes.
- a punctiform attachment can reduce the costs for the gluing and its effort, achieve ventilation or drainage between the glue points and thus avoid condensation.
- the steel profile can be statically better utilized by being subjected to at least one other direction of force, namely in one of the two remaining spatial directions perpendicular to the plane of the insulating glass slide, in whose edge bond the section of the steel profile engages.
- the steel profile itself can or only needs to be (closed) between the insulating glass panes. With the load-bearing blocking of the steel profile and the gluing of its section in an edge bond, an articulated and non-positive connection of two insulating glass panes can be achieved achieve. As a result, the adhesive joints of the bond are only loaded by normal stresses and shear stresses in the joint axis, which benefits their durability.
- the cross-sectional shape of the steel profile can advantageously be adapted to the respective installation situation, so that the steel profile remains visually as inconspicuous as possible.
- it can have a tubular cross-section or a T or double-T profile, the stem or the transverse T-leg of which can be suitably cut out to form tabs.
- an angle profile for example an L-shaped steel profile with two legs can be used, at least one leg of which is held between the insulating glass panes.
- the leg can protrude between the insulating glass panes so that it is quasi clamped between them—usually in a blocking—by an upper insulating glass pane resting on it and it resting on an end face of a lower insulating glass pane.
- At least one tab described above can be formed projecting at right angles on it.
- the steel profile offers a sufficiently rigid cross-section that is space-saving and relatively unobtrusive at the same time. In a corner of a building, particularly in a joint between a glass roof and a vertical glass wall, it can be incorporated almost invisibly.
- two insulating glass panes can meet at a butt joint, with at least one of the insulating glass panes having a glass overhang of a single glass pane on its edge facing the other insulating glass pane.
- the narrow face of the insulating glass pane can therefore have a (step) fold.
- the glass overhang can be formed on an outside of the facade formed from them.
- the glass overhang can cover a narrow longitudinal space in the area of the butt joint, in which the steel profile, its blocking and gluing and the like can be accommodated and thus optically concealed. From an outside, this can give the impression of a wider edge seal.
- Structural interfaces to the steel profile can be provided from the inside, such as tie rods or pressure rods for connection or support to an abutment.
- a glass overhang on both sides can enable a symmetrical design of the butt joint, which is optically particularly attractive for insulating glass panes that lie in the same plane.
- the glass overhang of the insulating glass pane forming the roof glazing can not only cover the end face of the slide forming the vertical glass wall, but also protrude beyond it.
- steel profiles of different quality can be used in the manner described above.
- a rustproof steel profile is used, because this allows a high resistance to moisture and in particular to condensation water to be achieved.
- stainless steel is maintenance-free in this respect.
- the anchor according to the invention can be used in particular to absorb horizontal loads on an upper edge of the wall glazing.
- the wall glazing can be supported on the roof glazing, for example to absorb wind pressure forces, while in the opposite direction, i.e. in the case of wind suction forces, it is held by the anchor.
- a steel cable can therefore serve as an anchor in sections. Because in the load direction described above, essentially tensile forces occur that have to be transferred to an abutment.
- a steel cable can be used in sections to divert it via the anchor, which offers another constructive and creative variant.
- figure 1 shows a basic spatial sketch of a glass pavilion with a length of 8.6 m, a width of 5.8 m and a height of 4.2 m. It consists of a glazed steel frame construction 1 and two all-glass extensions 2 attached on both sides to the narrow sides of the steel frame construction 1.
- the steel frame construction 1 represents an abutment to which the all-glass structures 2 constructed according to the invention are attached.
- the ring anchor 14 is connected at both of its ends directly and additionally via two tension rods 40 in between to the steel frame structure 1 of the pavilion.
- Horizontal loads on the roof glazing 10 such as wind pressure, snow and dead weight loads are carried in the area of the all-glass extensions 2 on three sides by the vertical wall glazing 12 arranged underneath. Solasten assumes a load-bearing bonding of the roof glazing panes 10 on the ring anchor 14.
- the wall glazing 12 of the all-glass extensions 2 are for wind suction and wind pressure loads along their lower horizontal edge in a clamp construction, not explained in detail, and along their upper horizontal edge at the butt joint 50 over in the figures 2 , 3 tabs 143 described in more detail of the ring anchor 14 or stored on a blocking.
- the roof glazing 10 is connected to the ring anchor 14 in the horizontal direction via a block and assumes a stiffening function of the U-shaped frame of the ring anchor 14 in the horizontal direction.
- FIG 2 shows a section through a butt joint 50 of a roof-wall construction of an all-glass extension 2.
- Its roof glazing 10 is designed as a pent roof, which meets the wall glazing 12 at the butt joint 50 and protrudes there with a projection 16 over the so-called high wall of the pent roof.
- Both the roof glazing 10 and the wall glazing 12 consist of insulating glass panes or multiple-pane insulating glass.
- the roof glazing 10 consists of a 10 mm thick pane 101 made of toughened safety glass (ESG), an adjoining pane space 102 of 12 mm, an 8 mm thick ESG pane 103, a subsequent pane space 104 also of 12 mm and a Pane package made of laminated safety glass made up of two partially toughened panes 105, 106 glued together, each with a thickness of 10 mm.
- the gaps between the panes 102, 104 are each sealed on the circumference between the glass panes 101 and 103 or 103 and 105 that border them and have a peripheral edge seal 107 with a conventional width of at least 6 mm.
- Each edge composite 107 is composed of a spacer 108 made of aluminum, the gluing and sealing 109 made of a two-component silicone elastomer between the adjacent glass panes 101, 103 or 103, 105 fixed and airtight.
- a suitable adhesive is available under the name Dow Corning® 993, for example.
- the roof glazing 10 has an end face 110 on the ridge side, on which the edge assemblies 107 and the panes 103, 105 and 106 terminate flush with one another. Only the toughened safety glass pane 101 projects beyond the end face 110 with the overhang 16 by 87 mm and thus gives a ridge-side edge region 11 of the roof glazing 10 a rebate.
- the wall glazing 12 also consists of multi-pane insulating glass, which, viewed from the outside inwards, consists of a 12 mm thick ESG pane 121, an adjoining pane space 122 of 14 mm thickness, an 8 mm thick ESG pane 123, another pane space 124 of 18 mm and a laminated safety glass pane made of two glued together ESG panes 125, 126, each 12 mm thick.
- the spaces between the panes 122, 124 are also maintained by edge bonds 127 made between the panes 121 and 123 and 123 and 125, respectively. They are also composed of spacers 128, described in more detail above, and an adhesive bond and seal 129.
- the insulating glass pane 12 has an end face 130 on the ridge side, on which the panes 123, 125, 126 and the edge assemblies 127 terminate flush. Only the toughened safety glass pane 121 protrudes perpendicularly beyond the end face 130 by 61 mm, so that the wall glazing 12 also runs out at its upper edge 13 in a rebate.
- the edge bond 127 of the wall glazing 12 on the inside of the building also has on the end face 130 a receiving pocket 131 made of anodised aluminum which is U-shaped in cross section and which is open towards the end face 130 . It is embedded in the non-load-bearing adhesive 129 of the edge seal 127, which is at least 12 mm wider than the edge seal 107.
- the roof glazing 10 and the wall glazing 12 are at an angle of slightly less than 90° to one another, with the end face 110 of the roof glazing 10 lying in the rebate or over the end face 130 and there being approximately aligned with the space 124 between the panes.
- the supernatant 16 of the roof glazing 10 is therefore not only on the end face 130, but also over the overhang 18 of the toughened safety glass pane 121.
- the roof glazing 10 and the wall glazing 12 enclose an approximately L-shaped space with their folds and between the projections 16, 18 and the end faces 110, 130, which is sealed airtight and watertight on the outside by an adhesive joint 20 and on the inside by an adhesive joint 22 .
- Two tabs 143 engage in the edge seal 127 of each individual insulating glass pane of the wall glazing 12, which is held on the ring anchor 14.
- the horizontal leg 142 is wedged between the end face 130 and the underside of the roof glazing 10 and bonded with the above-mentioned adhesive made of a two-component silicone elastomer.
- plastic strips 26 made of polyoxymethylene (POM) are wedged between the horizontal leg 142 on the one hand and the underside of the roof glazing 10 or the end face 130 on the toughened safety glass panes 125, 126 on the other hand and are additionally bonded there for load-bearing purposes.
- the vertical leg 141 is held in relation to the roof glazing 10 in the same way, in that a plastic strip 28 is wedged and glued between the end face 110 and the vertical leg 141 .
- the plastic strips 26, 28 are only attached to those sections of the vertical leg 141 in which a tab 143 is arranged on the horizontal leg 142.
- the projections 16, 18 carry cold foam insulation 30 and 32 on their respective insides, which run out towards the adhesive joint 20 to a round profile 34 made of polyurethane (PUR) that is undeformed only for drawing reasons.
- PUR polyurethane
- the annular anchor 14 runs horizontally and in a U-shape within the glass structure, encompasses the roof glazing 10 and is fastened to an abutment, not shown, at the free ends of its U-legs. Together with the roof glazing 10, the ring anchor 14 forms an immovable bracing plane.
- the cut according to figure 2 runs through one of its U-legs.
- figure 3 shows a section in the area of its transverse leg, namely in the area of a verge of the pent roof. Basically, here are largely the same Structural elements and their corresponding arrangement to one another, with the roof glazing 10 and the wall glazing 12 meeting at the verge at an angle of 90°.
- the overhang 161 of the roof glazing 10 is made shorter, so that it ends flush with an outside of the wall glazing 12 .
- a tie rod 40 is attached to the horizontal leg 142 of the ring anchor 14, which adjoins the horizontal leg 142 horizontally and thus in its extension and extends to an abutment, not shown.
- the ring anchor 14 thus runs completely inside the butt joint 50 between the roof glazing 10 and the wall glazing 12. It is connected at its free ends to the abutment, not shown, and is also supported horizontally by the tension rods 40 running parallel to its U-legs.
- the annular anchor 14 and its abutment consequently completely frame the roof glazing 10 on the peripheral side. It is thus mounted so that it cannot be moved horizontally and can therefore be used to stiffen the conservatory.
- the annular anchor 14 transfers vertical loads from wind pressure, snow and its own weight, which act on the roof glazing 10, via the horizontal leg 142, which is blocked and glued to the strips 26, onto the panes 125, 126 of the wall glazing 12 arranged underneath. Wind suction loads on the roof glazing 10 are transferred to the ring beam 14 by the gluing of the roof glazing 10 in the area of the blocking.
- both wind suction and wind pressure loads on the wall glazing 12 reach the inner edge bond 127 of the wall glazing 12, the receiving pocket 131 arranged there and the tab 143 glued therein ring anchor.
- the ring anchor 14 forwards wind pressure forces via the strip 28 to the roof glazing 10, which is supported on the abutment. Wind forces, on the other hand, are transmitted directly to the abutment, not shown, by the ring anchor 14 either via the tension rods 40 or via its U-legs running parallel thereto.
- the ring anchor 14 can be seen neither from an outside of the conservatory or its illustrated building edges nor from its inside. Because through the opaque Edge bond 127, 107 of the roof glazing 10 and the wall glazing 12 creates a "black frame" which is narrow and therefore inconspicuous in relation to the entire glass surface of the roof glazing 10 and the wall glazing 12. The meeting of the end faces 110, 130 and the overhangs 16, 18 at the butt joint 50 of the roof glazing 10 and the wall glazing 12 cover a barely recognizable space for the viewer, within which the ring anchor 14 is housed. As a result, the edge of the building where the roof glazing 10 and the wall glazing 12 meet is given a design that nevertheless appears slim and airy, without steel components being immediately recognizable. With the hardly impeded passage of light, the conservatory gives the impression of being made entirely of glass.
- the figures 4 (Horizontal section) and 5 (vertical section) show a further embodiment of the invention using a vertically running butt joint 60 between two sets of insulating glass panes of a vertical wall glazing 12.
- the structure of the sets of insulating glass panes corresponds to that according to FIG figures 1 and 2 .
- two completely flat end faces 130 meet in the butt joint 60 , which are closed on the outside by an adhesive joint 20 and on the inside by an adhesive joint 22 .
- In the butt joint 60 there are two edge bonds 127 opposite each other, namely two outer ones at the height of the pane spaces 122, at the height of which in the butt joint 60 a round profile 34 is also arranged.
- a receiving pocket 131 is introduced in the manner described above, which in a bond 129 fastens a strip-shaped tab 145 as the anchor head of a T-shaped steel profile 144, which is welded to a plate-shaped anchor shaft 146.
- the anchor shaft 146 protrudes approximately halfway into the butt joint 60 between the two end faces 130 and otherwise projects out of the butt joint 60 in the direction of an interior space.
- There it forms a coupling section for a tie rod 40 which is attached to an anchor body 150 on an abutment, z. B. on a steel plate that is anchored in a concrete wall.
- the second embodiment according to figures 4 and 5 consequently relates to a tie rod consisting of an anchor head, which is represented by the tabs 145 welded to the anchor shaft 146, and the anchor shaft 146, which enables a non-positive connection of the tension rod 40 as a tension element.
- the vertical wall glazing can be achieved with the steel profile 144 as a ring beam 12 reliably supported in the horizontal direction on an abutment.
- a U-shaped ring anchor could be formed in a horizontal butt joint with the steel profile 144.

Description
Die Erfindung betrifft eine Haltekonstruktion für Isolierglasscheiben insbesondere für raumbildende Verglasungen wie Wintergärten, Pavillons und dergleichen. Sie werden in der Regel aus Mehrscheibenisolierglas aufgebaut und umfassen eine Stahlkonstruktion, die möglichst zurückhaltend gestaltet ist, um den "luftigen" und lichtdurchfluteten Eindruck des Glasbauwerks möglichst wenig zu beeinträchtigen.The invention relates to a holding structure for insulating glass panes, in particular for space-forming glazing such as conservatories, pavilions and the like. They are usually made of multiple-pane insulating glass and include a steel construction that is designed as unobtrusively as possible in order to impair the "airy" and light-flooded impression of the glass structure as little as possible.
Die
Die
Aufgabe der Erfindung ist es daher, eine Ganzglaskonstruktion für Wintergärten, Pavillons oder dergleichen aus Isolierglasscheiben anzugeben, die eine hohe Tragfähigkeit aufweist und deren Stahlkonstruktion dennoch optisch möglichst unauffällig ist.The object of the invention is therefore to specify an all-glass construction for conservatories, pavilions or the like made of insulating glass panes which has a high load-bearing capacity and whose steel construction is nevertheless visually as inconspicuous as possible.
Diese Aufgabe wird mit einer Haltekonstruktion nach Anspruch 1 gelöst: Erfindungsgemäß umfasst die Haltekonstruktion ein an einem Widerlager montierbares Stahlprofil und mindestens zwei Isolierglasscheiben mit einem Randverbund an ihren Rändern, mit einer Stoßfuge zwischen den Isolierglasscheiben, wobei das Stahlprofil als Anker oder zumindest als Teilabschnitt eines Ankers in der Stoßfuge und parallel zu den Rändern verläuft und mit mindestens einem Abschnitt in den Randverbund einer Isolierglasscheibe eingreift und Kopplungsstellen für den Anschluss an das Widerlager aufweist, mit denen es entweder bündig mit den Glasscheiben am Widerlager anschließt oder aus der Stoßfuge der Glasscheiben herausreicht. Unter einem Anker ist im Bauwesen ein Bauteil zu verstehen, das aufgrund seiner Zugfestigkeit verschiedene und in der Regel artfremde Bauteile miteinander verbindet. Beispielsweise können Isolierglasscheiben einer Glasfront an einem selbständigen Gebäude als Widerlager aus Stahl oder Stahlbeton zu verankern sein. So können auf senkrecht stehende Isolierglasscheiben insbesondere Winddruck- und -sogkräfte wirken, die der Anker aufnehmen und an dem Widerlager abtragen muss, um die Stabilität der Glasfront beispielsweise eines Wintergartens sicherzustellen.This object is achieved with a holding structure according to claim 1: According to the invention, the holding structure comprises a steel profile that can be mounted on an abutment and at least two insulating glass panes with an edge bond at their edges, with a butt joint between the insulating glass panes, with the steel profile acting as an anchor or at least as a partial section of an anchor in the butt joint and parallel to the edges and engages with at least one section in the edge bond of an insulating glass pane and has coupling points for the connection to the abutment, with which it is either flush with the glass panes on the abutment or extends out of the butt joint of the glass panes. In construction, an anchor is a component that, due to its tensile strength, connects different and usually dissimilar components to one another. For example, insulating glass panes of a glass front can be anchored to an independent building as an abutment made of steel or reinforced concrete. In particular, wind pressure and suction forces can act on vertically positioned insulating glass panes, which the anchor must absorb and transfer to the abutment in order to ensure the stability of the glass front of a conservatory, for example.
Die erfindungsgemäße Konstruktion geht also von einem Widerlager wie einer Gebäudeau-ßenwand oder einer Stahlkonstruktion aus, an das sie und insbesondere das Stahlprofil anschließt. Sie stellt also keine statisch vollkommen selbständige Ganzglaskonstruktion dar. Die einzelnen Scheiben ihrer Mehrscheibenisolierverglasung bestehen aus Einzelscheiben mit einem Randverbund, an dem die Einzelscheiben miteinander luftdicht verklebt und versiegelt sind, um einen evakuierten oder gasgefüllten Scheibenzwischenraum zu bilden. Der Randverbund bildet vor allem eine schmale Stirnseite einer Isolierglasscheibe. Dort werden Abstandhalter zwischen den Einzelscheiben eingeklebt, um neben einem definierten Abstand auch für eine umfangseitige Abdichtung des Scheibenzwischenraums zu sorgen. Nebeneinander liegende Isolierglasscheiben treffen an den Stoßfugen aufeinander, so dass der Randverbund einer ersten Isolierglasscheibe parallel neben dem Randverbund einer zweiten Isolierglasscheibe zu liegen kommt. Eine Stoßfuge kann grundsätzlich zwischen zwei Isolierglasscheiben auftreten, die weitgehend in einer Ebene liegen. Anders als bei einem Schuppenstoß überdecken sich die Isolierglasscheiben an einer derartigen Stoßfuge nicht. Eine Stoßfuge kann auch zwischen zwei Isolierglasscheiben auftreten, die in einem Winkel zueinander stehen. An einer Gebäudeecke beträgt der Winkel regelmäßig 90°, kann davon aber sowohl in Richtung höherer Werte als auch in die Gegenrichtung abweichen. An einer Ecke überdecken sich die Isolierglasscheiben erfindungsgemäß nur an der Stirnseite der einen Isolierglasscheibe.The construction according to the invention is therefore based on an abutment such as a building exterior wall or a steel construction, to which it and in particular the steel profile is connected. It therefore does not represent a statically completely independent all-glass construction. The individual panes of your multiple-pane insulating glazing consist of individual panes with an edge bond on which the individual panes are glued and sealed together airtight to form an evacuated or gas-filled space between the panes. The edge bond primarily forms a narrow end face of an insulating glass pane. There, spacers are glued in between the individual panes in order to ensure not only a defined distance but also a peripheral sealing of the space between the panes. Insulating glass panes lying next to one another meet at the butt joints, so that the edge seal of a first insulating glass pane comes to lie parallel next to the edge seal of a second insulating glass pane. A butt joint can basically occur between two insulating glass panes that are largely in one plane. In contrast to a scale joint, the insulating glass panes do not overlap at such a joint. One Butt joints can also occur between two insulating glass panes that are at an angle to one another. At the corner of a building, the angle is regularly 90°, but can deviate from this both in the direction of higher values and in the opposite direction. According to the invention, the insulating glass panes overlap at one corner only on the front side of one insulating glass pane.
Erfindungsgemäß verläuft das Stahlprofil im Wesentlichen im Bereich der Stoßfuge, so dass es zwischen den beiden Isolierglasscheiben einer Stoßfuge angeordnet ist und damit parallel zu den Rändern der Isolierglasscheiben verläuft. Bereits dadurch lässt sich das Stahlprofil optisch sehr zurückhaltend anordnen. Zusätzlich greift das Stahlprofil mit einem Abschnitt in den Randverbund einer Isolierglasscheibe ein, um sie von ihrer schmalen Stirnseite aus zu halten. Anders als ein Umgreifen der Isolierglasscheibe an ihrem Rand, stellt der Eingriff des Stahlprofils in den Randverbund eine quasi "unsichtbare" Haltevorrichtung der Isolierglasscheibe dar. Das Stahlprofil und sein in den Randverbund eingreifender Abschnitt sind gleichsam in der Stoßfuge bzw. im Randverbund "versteckt". Die Erfindung nutzt also den ohnehin erforderlichen Randverbund der Isolierglasscheibe zusätzlich zu deren Befestigung am Stahlprofil. Anders als bei einer Verschraubung im Randverbund lotrecht zur Scheibenebene ist dafür kein aufwändiges Durchbohren einer Glasscheibe erforderlich. Die Erfindung bietet vielmehr die Möglichkeit sowohl einer linearen als auch einer punktuellen Halterung der Isolierglasscheibe am Randverbund. Damit kann sie mit geringem konstruktivem Aufwand an unterschiedliche Belastungen angepasst werden, beispielsweise durch Variation der Abstände der Abschnitte bei einer punktuellen Halterung oder durch Variation der Länge der Abschnitte bei einer linearen Halterung. Für den Anschluss an ein Widerlager bietet das Stahlprofil erfindungsgemäß schließlich Schnitt- bzw. Kopplungsstellen, in der Regel an seinen längsseitigen Enden, mit denen es zum Beispiel bündig mit den Glasscheiben am Widerlager anschließt oder aus der Stoßfuge der Glasscheiben herausreicht.According to the invention, the steel profile runs essentially in the area of the butt joint, so that it is arranged between the two insulating glass panes of a butt joint and thus runs parallel to the edges of the insulating glass panes. This alone allows the steel profile to be arranged in a very unobtrusive manner. In addition, a section of the steel profile engages in the edge seal of an insulating glass pane in order to hold it from its narrow front side. Unlike gripping around the edge of the insulating glass pane, the engagement of the steel profile in the edge seal represents a quasi "invisible" holding device for the insulating glass pane. The steel profile and its section engaging in the edge seal are "hidden" in the butt joint or in the edge seal. The invention thus uses the edge seal of the insulating glass pane, which is required anyway, in addition to its attachment to the steel profile. In contrast to a screw connection in the edge seal perpendicular to the plane of the pane, no time-consuming drilling through a glass pane is required. Rather, the invention offers the possibility of both a linear and a punctiform mounting of the insulating glass pane on the edge bond. It can thus be adapted to different loads with little design effort, for example by varying the distances between the sections in the case of a punctiform mounting or by varying the length of the sections in the case of a linear mounting. For the connection to an abutment, the steel profile according to the invention finally offers cuts or coupling points, usually at its longitudinal ends, with which it connects, for example, flush with the glass panes on the abutment or extends out of the butt joint of the glass panes.
Nach einer vorteilhaften Ausgestaltung der Erfindung kann das Stahlprofil einen Ringanker oder zumindest einen Abschnitt eines Ringankers bilden. Der Ringanker ist ein ringförmig geschlossenes Bauteil aus Stahl, das ein Auseinanderfallen der um- oder angeschlossenen Isolierglasscheiben verhindert, indem es einen in die Isolierglasscheiben eingeleiteten Schub senkrecht zu ihrer Erstreckungsebene aufnimmt. Ist der Ringanker aus einzelnen Teilabschnitten zusammengesetzt, so müssen die Verbindungen der Teilabschnitte untereinander ausreichende Zugspannungen aufnehmen können. Insofern kann sich der Ringanker aus dem Stahlprofil und einem Widerlager zusammensetzen, an dem das Stahlprofil anschließt. Das Widerlager kann seinerseits in einer Stahlkonstruktion oder in einer Betonkonstruktion bestehen, die stahlbewehrt ist. Jedenfalls ergänzt das Widerlager das Stahlprofil - nicht zwingend in geometrischer, sondern zumindest in statischer Hinsicht - zu einem Ring.According to an advantageous embodiment of the invention, the steel profile can form a ring beam or at least a section of a ring beam. The ring anchor is a ring-shaped, closed component made of steel that prevents the insulated glass panes that have been wrapped around or connected from falling apart by absorbing a thrust that is introduced into the insulating glass panes perpendicular to their plane of extension. If the ring anchor is made up of individual sections, the connections between the sections must be able to absorb sufficient tensile stress. In this respect, the ring anchor can Assemble the steel profile and an abutment to which the steel profile connects. The abutment can itself consist of a steel structure or a concrete structure which is steel reinforced. In any case, the abutment complements the steel profile - not necessarily in geometric terms, but at least in static terms - to form a ring.
Um möglichst unauffällig montierbar zu sein, sollte der Querschnitt des Stahlprofils möglichst schlank dimensioniert sein. Dann kann das Stahlprofil allerdings - vor allem bei einem unrunden Ringanker - nicht knicksteif genug sein, um Horizontalkräfte insbesondere auf längere ebene Glasfronten abfangen zu können. Nach einer vorteilhaften Ausgestaltung der Erfindung kann das Stahlprofil daher über zumindest einen Koppelungsabschnitt zum Anschluss eines Zugelements orthogonal zu seiner Erstreckungsrichtung verfügen. Das Zugelement kann das Stahlprofil am Widerlager abstützen bzw. es gegenüber dem Widerlager verspannen. Alternativ kann das Zugelement auch eine Abstützung oder Verspannung an einem gegenüberliegenden Stahlprofil als Teilabschnitt desselben Ringankers herstellen. Der Koppelungsabschnitt befindet sich nicht an den Enden des Stahlprofils, sondern in dessen Verlauf jenseits bzw. außerhalb seiner Enden, um das Stahlprofil in einem mittleren Bereich abzustützen. Auch mehrere Kopplungsabschnitte sind denkbar und sinnvoll. Weil durch Einsatz eines Zugelements eine maßgebliche freie Stützlänge des Stahlprofils verkürzt und das Stahlprofil damit größere Horizontallasten aufnehmen kann, als es sein Querschnitt bzw. dessen Flächenträgkeitsmoment allein zuließe, lassen sich bei Einsatz von Zugelementen längere Fassaden aus Isolierglasscheiben aufbauen.In order to be as inconspicuous as possible to install, the cross-section of the steel profile should be dimensioned as slim as possible. In this case, however, the steel profile - especially in the case of an out-of-round ring anchor - cannot be buckling-resistant enough to be able to absorb horizontal forces, especially on longer, flat glass fronts. According to an advantageous embodiment of the invention, the steel profile can therefore have at least one coupling section for connecting a tension element orthogonal to its direction of extension. The tension element can support the steel profile on the abutment or brace it against the abutment. Alternatively, the tension element can also provide support or bracing on an opposite steel profile as a section of the same ring anchor. The coupling section is not located at the ends of the steel profile, but in its course beyond or outside of its ends in order to support the steel profile in a central area. Several coupling sections are also conceivable and useful. Because the use of a tension element shortens a significant free support length of the steel profile and the steel profile can thus absorb greater horizontal loads than its cross section or its area moment of inertia alone would allow, longer facades made of insulating glass panes can be constructed if tension elements are used.
Nach einer zum Ringanker alternativen Ausgestaltung der Erfindung kann das Stahlprofil einen Zuganker aus einem Ankerkopf und einem Ankerschaft bilden. Als Ankerkopf ist der Abschnitt des Stahlprofils zu verstehen, der im Randverbund der Isolierglasscheibe gehalten ist. Den Ankerschaft bildet ein dazu quer verlaufender Koppelungsabschnitt des Stahlprofils, der einen Anschluss an ein Zugelement ermöglicht. Der Ankerschaft bietet also eine Befestigungsfläche zur Befestigung des Zugelements, sodass es Kräfte orthogonal zur Erstreckungsrichtung des Stahlprofils auf ein Widerlager abtragen kann. Dabei ist die Ausrichtung des Ankerschafts selbst von untergeordneter Bedeutung, solange sich das Zugelement daran in der Kraftübertragungsrichtung des Ankers befestigen lässt.According to an alternative embodiment of the invention to the ring anchor, the steel profile can form a tie rod from an anchor head and an anchor shaft. The anchor head is the section of the steel profile that is held in the edge bond of the insulating glass pane. The anchor shank is formed by a coupling section of the steel profile running transversely thereto, which enables connection to a tension element. The anchor shank thus offers a fastening surface for fastening the tension element, so that it can transfer forces to an abutment orthogonally to the direction in which the steel profile extends. The orientation of the anchor shaft itself is of secondary importance as long as the tension element can be attached to it in the force transmission direction of the anchor.
Der Abschnitt des Stahlprofils, der in den Randverbund eingreift, ist dort grundsätzlich dauerhaft zu befestigen. Er kann im Randverbund verkeilt, verklotzt, verrastet oder anderweitig befestigt werden. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Abschnitt des Stahlprofils im Randverbund verklebt. Dadurch lässt sich eine ausreichend dauerhafte Befestigung erreichen, die ohne den Einsatz zusätzlicher Konstruktionsmittel und ohne Berücksichtigung enger Toleranzen bauseits mit einem vertretbaren Aufwand vorgenommen werden kann. Als geeignete Klebstoffe sind beispielsweise Silikon-Klebstoffe in 2-Komponenten-Technologie bekannt. Die geringen Anforderungen an Toleranzen zwischen den Abschnitten des Stahlprofils einerseits und dem Randverbund der Isolierglasscheibe andererseits ermöglichen eine kostengünstige Herstellung der Bestandteile der erfindungsgemäßen Haltekonstruktion.The section of the steel profile that engages in the edge seal must always be permanently fastened there. It can be wedged, wedged, latched or otherwise in the edge seal to be attached. According to a further advantageous embodiment of the invention, the section of the steel profile is glued in the edge seal. As a result, a sufficiently permanent attachment can be achieved, which can be carried out on site at a reasonable cost without the use of additional construction means and without taking into account narrow tolerances. Silicone adhesives in 2-component technology, for example, are known as suitable adhesives. The low demands on tolerances between the sections of the steel profile on the one hand and the edge bond of the insulating glass pane on the other hand enable the components of the holding structure according to the invention to be manufactured at low cost.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Randverbund eine Aufnahmetasche auf, in der der Abschnitt des Stahlprofils verklebt wird bzw. ist. Sie kann ein separates Bauteil darstellen, das in den Randverbund eingebracht wird, oder im Abstandhalter des Randprofils ausgebildet sein. Das Material der Aufnahmetasche einerseits und das Material des Abschnitts am Stahlprofil andererseits ermöglichen die Definition von geeigneten Klebepartnern, auf die der Klebstoff abgestimmt werden kann. Umgekehrt kann die Anordnung der Aufnahmetasche eine Abstimmung ihres Materials unabhängig vom übrigen Material des Randverbunds auf den Klebstoff ermöglichen. Die Befestigung der ggf. separaten Aufnahmetasche am Randverbund kann werkseitig und damit mit hoher Qualität, Dauerhaftigkeit und Zuverlässigkeit erfolgen. Zudem bietet die Anordnung einer Aufnahmetasche im Randverbund die Möglichkeit, die Abmessungen einer Klebefuge zwischen der Aufnahmetasche einerseits und dem Abschnitt des Stahlprofils andererseits insbesondere den statischen Anforderungen gemäß zu definieren. Zusätzlich kann unabhängig von den Abmessungen des Randverbunds immer dieselbe Aufnahmetasche ausgebildet oder verwendet werden, womit sich auch bei unterschiedlichen Dimensionen von Isolierglasscheiben bzw. ihres Randverbunds gleiche bzw. wiederholbare Verhältnisse bei der Verklebung er zielen lassen. Dadurch lässt sich die Verklebung, insbesondere sofern sie bauseits erfolgt, mit hoher Qualität herstellen. Schließlich lässt sich auch eine erforderliche oder gewünschte Klebstoffdicke einstellen und die Klebefuge zuverlässiger berechnen.According to a further advantageous embodiment of the invention, the edge bond has a receiving pocket in which the section of the steel profile is or is glued. It can represent a separate component that is introduced into the edge seal, or it can be formed in the spacer of the edge profile. The material of the receiving pocket on the one hand and the material of the section on the steel profile on the other allow the definition of suitable adhesive partners to which the adhesive can be matched. Conversely, the arrangement of the receiving pocket can allow its material to be matched to the adhesive independently of the remaining material of the edge composite. The possibly separate receiving pocket can be attached to the edge seal in the factory and thus with high quality, durability and reliability. In addition, the arrangement of a receiving pocket in the edge bond offers the possibility of defining the dimensions of an adhesive joint between the receiving pocket on the one hand and the section of the steel profile on the other hand, in particular in accordance with the static requirements. In addition, regardless of the dimensions of the edge seal, the same receiving pocket can always be formed or used, which means that the same or repeatable conditions can be achieved when gluing even with different dimensions of insulating glass panes or their edge seal. This means that the bonding can be of high quality, especially if it is done on site. Finally, a required or desired adhesive thickness can also be set and the adhesive joint can be calculated more reliably.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann die Aufnahmetasche als ein in den Randverbund eingeklebtes U-Profil ausgebildet sein. Damit bildet es eine definierte Schnittstelle in der Isolierglasscheibe zur Einbindung des Abschnitts des Stahlprofils, die sowohl linear als auch punktuell ausgebildet oder belastet sein kann. Das U-Profil kann beispielsweise aus Aluminium oder Kunststoff ausgebildet sein, womit es sich mit geringem Aufwand herstellen und in den Randverbund der Isolierglasscheibe mit bekannten Technologien einbinden lässt.According to a further advantageous embodiment of the invention, the receiving pocket can be designed as a U-profile glued into the edge seal. It thus forms a defined interface in the insulating glass pane for integrating the section of the steel profile, which can be configured linearly or at points or loaded. The U-profile can, for example be made of aluminum or plastic, which means that it can be produced with little effort and integrated into the edge seal of the insulating glass pane using known technologies.
Erfindungsgemäß bindet das Stahlprofil mit einem Abschnitt in die Isolierglasscheibe bzw. in deren Randverbund ein. Grundsätzlich kann der Abschnitt des Stahlprofils linear, beispielsweise mit einem Profilschenkel, oder punktuell in den Randverbund eingreifen. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann der Abschnitt als Lasche ausgebildet sein, die am Stahlprofil angeformt ist. Sie kann dort separat angeschweißt oder aus dem Stahlprofil ausgeschnitten sein. Damit definiert sie eine punktuelle Befestigung des Stahlprofils, die durch eine Vielzahl von nebeneinander liegenden Laschen linear wirken kann. Eine punktuelle Befestigung kann bezüglich der Herstellung der Verklebung vorteilhaft sein, weil sie kürzere Klebefugen, eine geringere Klebefläche und damit den Vorteil eines geringeren Aufwands bieten kann. Sie kann auch konstruktiv ausreichend sein, indem sie beispielsweise an nur zwei Stellen in den Randverbund einer Isolierglasscheibe eingreift.According to the invention, a section of the steel profile is integrated into the insulating glass pane or into its edge seal. In principle, the section of the steel profile can engage in the edge bond linearly, for example with a profile leg, or selectively. According to a further advantageous embodiment of the invention, the section can be designed as a lug which is formed on the steel profile. It can be welded on separately there or cut out of the steel profile. In this way, it defines a selective fastening of the steel profile, which can have a linear effect due to a large number of brackets lying next to one another. A punctiform attachment can be advantageous with regard to the production of the bond, because it can offer shorter adhesive joints, a smaller adhesive surface and thus the advantage of less effort. It can also be structurally sufficient, for example by engaging in the edge seal of an insulating glass pane at only two points.
Der erfindungsgemäße Eingriff des Stahlprofils in den Randverbund der Isolierglasscheibe überträgt in Wesentlichen Kräfte in einer Richtung lotrecht zur gehaltenen Isolierglasscheibe, meist Winddruck- und -sogkräfte. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann das Stahlprofil zusätzlich in der Stoßfuge zwischen den Isolierglasscheiben gehalten bzw. befestigt sein. Die Halterung kann linear oder punktuell erfolgen, beispielsweise durch ein Verklotzen oder Verkleben. Dadurch kann eine geeignete, ggf. möglichst großflächige Kraftübertragung insbesondere von Druckkräften zwischen den Isolierglasscheiben einerseits und dem Stahlprofil andererseits erreicht werden. Bei Druckkräften kann die Halterung so zu einer geringen Flächenpressung im Bereich des Randverbunds der Isolierglasscheiben führen. Eine punktuelle Befestigung kann die Kosten für die Verklebung und deren Aufwand reduzieren, eine Belüftung bzw. Entwässerung zwischen den Klebepunkten erzielen und damit eine Kondensatbildung vermeiden. Jedenfalls kann das Stahlprofil statisch besser ausgenutzt werden, indem es in mindestens einer weiteren Kraftrichtung beaufschlagt wird, nämlich in einer der beiden verbleibenden Raumrichtungen rechtwinklig zur Ebene der Isolierglasschiebe, in deren Randverbund der Abschnitt des Stahlprofils eingreift. Das Stahlprofil selbst kann bzw. braucht nur zwischen den Isolierglasscheiben verklotzt (zu) sein. Mit der tragenden Verklotzung des Stahlprofils und der Verklebung seines Abschnitts in einem Randverbund lässt sich eine gelenkige und kraftschlüssige Verbindung zweier Isolierglasschieben erzielen. Dadurch werden die Klebefugen der Verklebung ausschließlich durch Normalspannungen und Schubspannungen in Fugenachse belastet, was ihrer Dauerhaftigkeit zugutekommt.The inventive engagement of the steel profile in the edge seal of the insulating glass pane essentially transmits forces in a direction perpendicular to the insulating glass pane held, mostly wind pressure and wind suction forces. According to a further advantageous embodiment of the invention, the steel profile can also be held or fastened in the butt joint between the insulating glass panes. The mount can be linear or point-by-point, for example by blocking or gluing. As a result, a suitable force transmission, possibly over the largest possible area, can be achieved, in particular of compressive forces between the insulating glass panes on the one hand and the steel profile on the other. In the case of compressive forces, the bracket can lead to a low surface pressure in the area of the edge bond of the insulating glass panes. A punctiform attachment can reduce the costs for the gluing and its effort, achieve ventilation or drainage between the glue points and thus avoid condensation. In any case, the steel profile can be statically better utilized by being subjected to at least one other direction of force, namely in one of the two remaining spatial directions perpendicular to the plane of the insulating glass slide, in whose edge bond the section of the steel profile engages. The steel profile itself can or only needs to be (closed) between the insulating glass panes. With the load-bearing blocking of the steel profile and the gluing of its section in an edge bond, an articulated and non-positive connection of two insulating glass panes can be achieved achieve. As a result, the adhesive joints of the bond are only loaded by normal stresses and shear stresses in the joint axis, which benefits their durability.
Die Querschnittsform des Stahlprofils kann vorteilhaft an die jeweilige Einbausituation angepasst werden, so dass das Stahlprofil optisch möglichst unauffällig bleibt. Es kann beispielsweise einen Rohrquerschnitt oder ein T- oder Doppel-T-Profil aufweisen, dessen Stiel oder dessen quer verlaufender T-Schenkel zur Ausbildung von Laschen geeignet ausgeschnitten sein kann. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann ein Winkelprofil, beispielsweise ein L-förmiges Stahlprofil mit zwei Schenkeln zum Einsatz kommen, dessen zumindest einer Schenkel zwischen den Isolierglasscheiben gehalten ist. Dazu kann der Schenkel zwischen die Isolierglasscheiben ragen, so dass er zwischen ihnen - in der Regel in einer Verklotzung - quasi eingeklemmt ist, indem eine obere Isolierglasscheibe auf ihm und er auf einer Stirnseite einer unteren Isolierglasscheibe aufliegt. An ihm kann wenigstens eine oben beschriebene Lasche rechtwinklig abstehend angeformt sein. Mit einem winkel- bzw. L-förmigen Querschnitt bietet das Stahlprofil einen ausreichend steifen Querschnitt, der zugleich platzsparend und optisch verhältnismäßig unauffällig ist. In einer Gebäudeecke, insbesondere in einer Fuge zwischen einem Glasdach und einer vertikalen Glaswand kann es nahezu unsichtbar eingebunden sein.The cross-sectional shape of the steel profile can advantageously be adapted to the respective installation situation, so that the steel profile remains visually as inconspicuous as possible. For example, it can have a tubular cross-section or a T or double-T profile, the stem or the transverse T-leg of which can be suitably cut out to form tabs. According to a further advantageous embodiment of the invention, an angle profile, for example an L-shaped steel profile with two legs can be used, at least one leg of which is held between the insulating glass panes. For this purpose, the leg can protrude between the insulating glass panes so that it is quasi clamped between them—usually in a blocking—by an upper insulating glass pane resting on it and it resting on an end face of a lower insulating glass pane. At least one tab described above can be formed projecting at right angles on it. With an angular or L-shaped cross-section, the steel profile offers a sufficiently rigid cross-section that is space-saving and relatively unobtrusive at the same time. In a corner of a building, particularly in a joint between a glass roof and a vertical glass wall, it can be incorporated almost invisibly.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung können sich an einer Stoßfuge zwei Isolierglasscheiben treffen, wobei zumindest eine der Isolierglasscheiben einen Glasüberstand einer Einzelglasscheibe an ihrem der anderen Isolierglasscheibe zugewandten Rand aufweist. Die schmale Stirnseite der Isolierglasscheibe kann also einen (Stufen-) Falz aufweisen. Vorteilhafter Weise kann der Glasüberstand auf einer Außenseite der aus ihnen gebildeten Fassade ausgebildet sein. Der Glasüberstand kann einen schmale längsverlaufenden Raum im Bereich der Stoßfuge abdecken, in dem das Stahlprofil, dessen Verklotzung und Verklebung und dergleichen untergebracht und damit optisch verdeckt sein kann. Von einer Außenseite kann sich dadurch der Eindruck eines breiteren Randverbunds ergeben. Von innen können sich konstruktive Schnittstellen zum Stahlprofil bieten, wie zum Beispiel Zugbänder oder Druckstangen zum Anschluss oder Abstützen an einem Widerlager. Ein beidseitiger Glasüberstand kann eine symmetrische Ausbildung der Stoßfuge ermöglichen, die sich optisch insbesondere bei Isolierglasscheiben anbieten, die in derselben Ebene liegen. Bei Isolierglasscheiben, die in einem Winkel zueinander stehen, können sich auch ungleiche Falzausbildungen der beiden benachbarten Isolierglasscheiben anbieten. So kann bei Ausbildung einer Traufe der Glasüberstand der das Dachverglasung bildenden Isolierglasscheibe nicht nur die Stirnseite der die vertikale Glaswand bildenden Schiebe überdecken, sondern noch über sie überstehen.According to a further advantageous embodiment of the invention, two insulating glass panes can meet at a butt joint, with at least one of the insulating glass panes having a glass overhang of a single glass pane on its edge facing the other insulating glass pane. The narrow face of the insulating glass pane can therefore have a (step) fold. Advantageously, the glass overhang can be formed on an outside of the facade formed from them. The glass overhang can cover a narrow longitudinal space in the area of the butt joint, in which the steel profile, its blocking and gluing and the like can be accommodated and thus optically concealed. From an outside, this can give the impression of a wider edge seal. Structural interfaces to the steel profile can be provided from the inside, such as tie rods or pressure rods for connection or support to an abutment. A glass overhang on both sides can enable a symmetrical design of the butt joint, which is optically particularly attractive for insulating glass panes that lie in the same plane. In the case of insulating glass panes that are at an angle to one another, there can also be offer unequal fold formations of the two adjacent insulating glass panes. Thus, when an eaves is formed, the glass overhang of the insulating glass pane forming the roof glazing can not only cover the end face of the slide forming the vertical glass wall, but also protrude beyond it.
Grundsätzlich lassen sich Stahlprofile unterschiedlicher Qualität in der vorbeschriebenen Weise einsetzen. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kommt ein nicht rostendes Stahlprofil zum Einsatz, weil sich dadurch eine hohe Beständigkeit gegen Feuchtigkeit und insbesondere gegen Kondenswasser erzielen lässt. Anders als lackierte Stahlprofile, deren Lackschicht fehlerhaft und mit vertretbarem Aufwand nicht reparabel sein kann, ist nicht rostender Stahl insofern wartungsfrei.In principle, steel profiles of different quality can be used in the manner described above. According to a further advantageous embodiment of the invention, a rustproof steel profile is used, because this allows a high resistance to moisture and in particular to condensation water to be achieved. Unlike painted steel profiles, whose paint layer can be faulty and cannot be repaired with reasonable effort, stainless steel is maintenance-free in this respect.
Der erfindungsgemäße Anker kann insbesondere der Aufnahme von Horizontalllasten auf einen oberen Rand der Wandverglasung dienen. In einer zum Widerlager hin weisenden Richtung lässt sich die Wandverglasung zum Beispiel zur Aufnahme von Winddruckkräften an der Dachverglasung abstützten, in der Gegenrichtung dagegen, also bei Windsogkräften, hält sie der Anker. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung kann daher abschnittsweise ein Stahlseil als Anker dienen. Denn in der oben beschriebenen Belastungsrichtung treten im Wesentlichen Zugkräfte auf, die auf ein Widerlager übertragen werden müssen. Ihre Ableitung über den Anker kann abschnittsweise ein Stahlseil übernehmen, womit sich eine weitere konstruktive und gestalterische Variante bietet.The anchor according to the invention can be used in particular to absorb horizontal loads on an upper edge of the wall glazing. In a direction pointing towards the abutment, the wall glazing can be supported on the roof glazing, for example to absorb wind pressure forces, while in the opposite direction, i.e. in the case of wind suction forces, it is held by the anchor. According to a further advantageous embodiment of the invention, a steel cable can therefore serve as an anchor in sections. Because in the load direction described above, essentially tensile forces occur that have to be transferred to an abutment. A steel cable can be used in sections to divert it via the anchor, which offers another constructive and creative variant.

Die Dachverglasung 10 weist firstseitig eine Stirnseite 110 auf, an der die Randverbünde 107 und die Scheiben 103, 105 und 106 miteinander bündig abschließen. Lediglich die ESG-Scheibe 101 überragt die Stirnseite 110 mit dem Überstand 16 um 87 mm und verleiht damit einem firstseitigen Randbereich 11 der Dachverglasung 10 einen Falz.The
Die Wandverglasung 12 besteht ebenfalls aus Mehrscheibenisolierglas, das sich von außen nach innen betrachtet aus einer 12 mm starken ESG-Scheibe 121, einem anschließenden Scheibenzwischenraum 122 von 14 mm Stärke, einer 8 mm starken ESG-Scheibe 123, einem weiteren Scheibenzwischenraum 124 von 18 mm und einer Verbundsicherheitsglasscheibe aus zwei miteinander verklebten, jeweils 12 mm starken ESG-Scheiben 125, 126 zusammensetzt. Auch die Scheibenzwischenräume 122, 124 werden durch Randverbünde 127 aufrechterhalten, die zwischen den Scheiben 121 und 123 bzw. 123 und 125 hergestellt sind. Auch sie setzten sich aus oben näher beschriebenen Abstandhaltern 128 und einer Verklebung und Versiegelung 129 zusammen.The
Die Isolierglasscheibe 12 weist firstseitig eine Stirnseite 130 auf, an der die Scheiben 123, 125, 126 und die Randverbünde 127 bündig abschließen. Lediglich die ESG-Scheibe 121 steht mit einem Überstand von 61 mm senkrecht über die Stirnseite 130 hinaus, so dass auch die Wandverglasung 12 an ihrem oberen Rand 13 in einem Falz ausläuft.The insulating
Der gebäudeinnere Randverbund 127 der Wandverglasung 12 weist an der Stirnseite 130 außerdem eine im Querschnitt U-förmige Aufnahmetasche 131 aus eloxiertem Aluminium auf, die zur Stirnseite 130 hin geöffnet ist. Sie ist in der nicht tragenden Verklebung 129 des Randverbunds 127 eingebettet, der mit mind. 12 mm breiter als der Randverbund 107 ausfällt.The
Die Dachverglasung 10 und die Wandverglasung 12 stehen in einem Winkel von etwas weniger als 90° zueinander, wobei die Stirnseite 110 der Dachverglasung 10 in dem Falz bzw. über der Stirnseite 130 liegt und dort etwa mit dem Scheibenzwischenraum 124 fluchtet. Der Überstand 16 der Dachverglasung 10 steht folglich nicht nur über die Stirnseite 130, sondern auch über den Überstand 18 der ESG-Scheibe 121 über. Die Dachverglasung 10 und die Wandverglasung 12 schließen mit ihren Falzen und zwischen den Überständen 16, 18 und den Stirnseiten 110, 130 einen etwa L-förmigen Raum ein, der durch eine Klebefuge 20 außenseitig und durch eine Klebefuge 22 innenseitig luft- und wasserdicht abgeschlossen ist.The
In dem L-förmigen Raum verläuft ein gleichschenkliger L-förmiger Ringanker 14 aus nichtrostendem Stahl mit einem vertikal verlaufenden Schenkel 141 und einem horizontal verlaufenden Schenkel 142. An seinem horizontalen Schenkel 142 sind unterseitig vertikal abstehende Laschen 143 angeschweißt, die in die Aufnahmetaschen 131 eingreifen und dort mittels einer Verklebung 24 befestigt sind. Sie stellen eine mechanische Sicherung insbesondere gegen Windsog dar. In jede einzelne Isolierglasscheibe der Wandverglasung 12, die am Ringanker 14 gehalten wird, greifen zwei Laschen 143 in deren Randverbund 127 ein. Der horizontale Schenkel 142 ist zwischen der Stirnseite 130 und der Unterseite der Dachverglasung 10 verklotzt und mit dem oben bereits erwähnten Klebstoff aus einem Zweikomponenten-Silikon-Elastomer verklebt. Dazu sind etwa 200 mm lange Kunststoffleisten 26 aus Polyoxymethylen (POM) jeweils zwischen dem horizontalen Schenkel 142 einerseits und der Unterseite der Dachverglasung 10 bzw. der Stirnseite 130 auf den ESG-Scheiben 125, 126 andererseits verkeilt und dort zusätzlich tragend verklebt. In prinzipiell gleicher Weise ist der vertikale Schenkel 141 gegenüber der Dachverglasung 10 gehalten, indem eine Kunststoffleiste 28 zwischen der Stirnseite 110 und dem vertikalen Schenkel 141 verklotzt und verklebt ist. Die Kunststoffleisten 26, 28 sind hierbei nur in denjenigen Abschnitten des vertikalen Schenkels 141 angebracht, in denen eine Lasche 143 am horizontalen Schenkel 142 angeordnet ist.An isosceles L-shaped
Schließlich tragen die Überstände 16, 18 auf ihren jeweiligen Innenseite eine Kaltschaumisolierung 30 bzw. 32, die auf die Klebefuge 20 hin auf ein nur aus zeichnerischen Gründen unverformtes Rundprofil 34 aus Polyurethan (PUR) auslaufen.Finally, the
Der Ringanker 14 verläuft innerhalb des Glasbauwerks horizontal und U-förmig, umfasst die Dachverglasung 10 und ist an den freien Enden seiner U-Schenkel an einem nicht dargestellten Widerlager befestigt. Zusammen mit der Dachverglasung 10 bildet der Ringanker 14 eine unverschiebliche Aussteifungsebene. Der Schnitt gemäß
Damit verläuft der Ringanker 14 vollständig innerhalb der Stoßfuge 50 zwischen der Dachverglasung 10 und der Wandverglasung 12. Er ist an seinen freien Enden mit dem nicht dargestellten Widerlager verbunden und zusätzlich durch die parallel zu seinen U-Schenkeln verlaufenden Zugstäbe 40 horizontal gelagert. Der Ringanker 14 und sein Widerlager rahmen folglich die Dachverglasung 10 umfangsseitig vollständig ein. Sie ist damit horizontal unverschieblich gelagert und kann dadurch zur Aussteifung des Wintergartens herangezogen werden.The
Der Ringanker 14 gibt vertikale Lasten aus Winddruck, Schnee und Eigengewicht, die auf die Dachverglasung 10 wirken, über den mit den Leisten 26 verklotzen und verklebten horizontalen Schenkel 142 auf die darunter angeordneten Scheiben 125, 126 der Wandverglasung 12 ab. Windsoglasten auf die Dachverglasung 10 werden durch die Verklebung der Dachverglasung 10 im Bereich der Verklotzung mit dem Ringanker 14 auf jene übertragen.The
Horizontale Kräfte, die auf die Wandverglasung 12 wirken, nimmt ebenfalls der Ringanker 14 auf: sowohl Windsog- als auch Winddrucklasten auf die Wandverglasung 12 gelangen über den inneren Randverbund 127 der Wandverglasung 12, die dort angeordnete Aufnahmetasche 131 und die darin verklebte Lasche 143 auf den Ringanker. Winddruckkräfte leitet der Ringanker 14 über die Leiste 28 auf die Dachverglasung 10 weiter, die sich am Widerlager abstützt. Windzugkräfte dagegen überträgt der Ringanker 14 entweder über die Zugstäbe 40 oder über seine parallel dazu verlaufenden U-Schenkel unmittelbar auf das nicht dargestellte Widerlager.Horizontal forces acting on the
Weder von einer Außenseite des Wintergartens bzw. seiner dargestellten Gebäudekanten noch von seiner Innenseite aus lässt sich der Ringanker 14 erkennen. Denn durch den undurchsichtigen Randverbund 127, 107 der Dachverglasung 10 und der Wandverglasung 12 entsteht ein "schwarzer Rahmen", der im Verhältnis zur gesamten Glasfläche der Dachverglasung 10 und der Wandverglasung 12 schmal und daher unauffällig ausfällt. Durch das Aufeinandertreffen der Stirnseiten 110, 130 und durch die Überstände 16, 18 an der Stoßfuge 50 der Dachverglasung 10 und der Wandverglasung 12 verdeckt er einen für den Betrachter kaum erkennbarer Raum, innerhalb dem der Ringanker 14 untergebracht ist. Dadurch erhält die Gebäudekante am Zusammentreffen der Dachverglasung 10 und der Wandverglasung 12 eine dennoch schlank und luftig erscheinende Gestaltung, ohne dass Stahlbauteile unmittelbar erkennbar wären. Mit dem kaum behinderten Lichtdurchtritt erweckt der Wintergarten damit den Eindruck, ausschließlich aus Glas zu bestehen.The

Das zweite Ausführungsbeispiel gemäß den
Da es sich bei den vorhergehenden, detailliert beschriebenen Konstruktionen um Ausführungsbeispiele handelt, können sie in üblicher Weise vom Fachmann in einem weiten Umfang modifiziert werden, ohne den Bereich der Erfindung zu verlassen. Insbesondere können auch die konkreten Ausgestaltungen des Ringankers in anderen Querschnitten als in dem hier beschriebenen erfolgen. Ebenso können die Falze der Dach- und Wandverglasung in einer anderen Form ausgestaltet werden, wenn dies aus Konstruktionsgründen bzw. designerischen Gründen notwendig ist. Weiterhin schließt die Verwendung der unbestimmten Artikel "ein" bzw. "eine" nicht aus, dass die betreffenden Merkmale auch mehrmals oder mehrfach vorhanden sein können.Since the constructions described in detail above are exemplary embodiments, they can be modified to a large extent in the usual manner by those skilled in the art without departing from the scope of the invention. In particular, the concrete configurations of the ring anchor can also be made in cross sections other than those described here. The folds of the roof and wall glazing can also be designed in a different shape if this is necessary for construction or design reasons. Furthermore, the use of the indefinite article "a" or "an" does not exclude the possibility that the characteristics in question can also be present more than once.
