Description

The invention relates to a post-rung construction, especially for facades or roofs, to accommodate large areas Filling elements, in particular glass panes or facade panels.

In the case of three-dimensional mullion-rung constructions the posts and rungs are not arranged in one plane, but are located inside the mullion rungs Construction kinks where the horizontal Direction adjacent to a post or in vertical Direction of glass panes adjacent to a rung or Stand facade panels at an angle to each other. Such three-dimensional mullion bar constructions are common in the form of polygon facades or pyramids or domes executed.

The substructure of facades or roofs in the form of a post On the one hand, rung construction has the task of Record and close glass panes or facade panels fix; on the other hand, penetrated or condensed Drain liquid specifically and for a good one Ensure ventilation of the facade. To all of these To meet requirements, one grabs in technology in the Rule on customized, d. H. to special requirements coordinated solutions back, especially at  Construction of three-dimensional facades or roofs with complex shapes that cost manufacturing and assembly increase significantly. For this reason, there is an urgent one Need for a three-dimensional mullion rungs Construction that in the manner of a kit system provides a limited number of different elements with which three-dimensional post-rung constructions as Substructure for facades or roofs with one if possible variable shape can be erected.

The invention is based on the technical problem Post-rung construction to create the case perfect water drainage a high variability with respect to the shape.

This technical problem is solved by a mullion rung Construction solved with the feature of claim 1.

In the inventive solution according to claim 1 includes those on three-dimensional mullion rungs Constructions expandable post-rung construction as Hollow profiles designed posts and / or as hollow profiles trained rungs on the or the kinks of the Post-rung construction, each with two arch-shaped Fastening bars on the posts and / or rungs which each have mounting rails for sealing elements and at a predetermined angle to each other Mounting rail are attachable.

This allows both the post and the Rungs arbitrary angles in a relatively large Set the angular range and at the same time the sealing elements each align so that the fillers, especially Glass panes or facade panels in the best possible way  sealed way between the sealing elements will. The stepless adjustability of a desired angle between adjacent filling elements, usually in the form of glass panes or facade panels, can with a small number of different system elements high variability regarding the achievable design and Shaping of facades or roofs can be achieved.

The mounting rails for sealing elements preferably have a channel-shaped contact surface that corresponds to the arcuate mounting webs is shaped. This offers the Advantage that between the mounting rails and the arcuate attachment webs on the post and / or the Rung forms a large contact area to the occurring Transfer forces to the posts and / or rungs.

According to a preferred embodiment, the posts and Rungs axially symmetrical. An axisymmetric Training offers the advantage that both are combined in one Posts or a rung fasteners, but even only one of the two filling elements in a predetermined one Angle can be attached. This plays for example the installation direction in the area between a flat facade and a sloping roof surface doesn't matter because the Desired angular arrangement of the facade panel in the transition to the roof area on both sides of the axisymmetric trained rung can be attached.

Preferably, the posts and rungs have on the On the front, a centrally arranged receptacle for fastening a spacer bar. Under the front is the Facing side of the rung and the Understood post. The attachment of a spacer bar is important because on this one on the  Facade outside, d. H. outside the filler arranged, cover strip is attachable, which, in turn Seals provided, the filling elements from the Facade outside against the ingress of moisture seals and holds the filling element.

The spacer bar preferably has fastening grooves, in the associated fasteners of the sealing elements intervention. This allows the spacer on the one hand Posts or attached to the rung; to the others can have a continuous, liquid-tight barrier along the front of the post or rung getting produced. Finally, this serves liquid and vapor-tight barrier of shielding undesirable Heat radiation between the outside and inside of the facade.

According to a preferred embodiment, the sealing elements each have a stripe shape and have Pull-out slots along which the sealing elements can be divided. This can be done directly on site, i.e. H. on the construction site, on a simple way an overlapping connection between the Sealing elements along the rungs and the sealing elements along the posts in the joint area between posts and Rungs are made.

The sealing elements preferably overlap along the Rung and the sealing elements along the post so that the sealing element along the rung to the outside of the Facade or the roof is arranged. This leaves the water that has penetrated behind the facade panel or the liquid condensed out in this area specifically in the vertically arranged chutes along the posts convict.  

According to a preferred embodiment, the Sealing elements along the rungs as well as the sealing elements along the posts each have a drainage channel, the Drainage channel of the sealing elements along the post in Butt area between the posts and the rung of the drainage channels reaches behind the sealing elements along the rung. By this training of interlocking drainage channels the penetrated or condensed can be targeted Drain off liquid as the drainage channels along the Posts from the drainage channels along the rungs completely absorb the transported liquid and can deliberately dissipate.

The hollow profiles of the posts and rungs are preferably in one piece from sheet metal, preferably sheet steel rolled.

The invention is explained below purely by way of example using the attached drawings, in which:

Fig. 1 is a horizontal section through a post section with an angle for the next recording track and the sealing elements employed therein;

Figure 2 shows a vertical section through a post-rung construction;

Fig. 3 shows a horizontal section through a post-rung construction;

Fig. 4 is a horizontal section through a facade; and

Fig. 5 shows another embodiment of a facade in the horizontal section in the area of a post.

Fig. 1 shows a horizontal section through the hollow profile of a post with the components of the invention mounted thereon. The post 12 is made of metal and is preferably rolled from sheet steel. The post profile is axially symmetrical with respect to the axis 14 shown in FIG. I, which runs perpendicular to the rear side 16 opposite the front side. The rear side 16 of the mullion profile 5 merges with a production-related, small transition radius into a likewise flat side wall 18 of the mullion profile, each of which merges into an arcuate fastening web 20 on its end facing the outside of the facade. The arcuate region 20 is preferably a loop of the rolled post profile with a substantially constant curvature. Due to the loop-shaped design of the arcuate area, the metal sheet is double in this area and a higher strength is achieved in this area. The arcuate region 20 , as shown in FIG. 1, describes an arc that corresponds approximately to a quarter circle. Finally, a receptacle 22 is also formed on the post profile 12 , which forms a groove-shaped groove in the longitudinal direction of the post and serves to accommodate various fastening elements, but also to attach a spacer strip 24 .

The post profile 12 is designed as a closed hollow profile, a longitudinal seam being formed in a suitable area of the post profile for production reasons.

20 mounting rails 26 for sealing elements are fastened to the post section 12 in each case on the arcuate regions. The mounting rails 26 are also rolled from metal, in particular steel, and can be pushed onto the mounting bracket 28 in the longitudinal direction of the post 12 , ie perpendicular to the plane of the drawing in FIG. 1. As is indicated in FIG. 1 by dash-dotted lines, the fastening brackets 28 , which are preferably made of spring steel, are fixed on the arcuate region 20 of the post profile by one or more suitable fastening elements along or along their extension. The fastening between the fastening bracket 28 and the post profile can be designed, for example, in such a way that 20 elongated holes are formed at regular intervals in the arcuate region, through which suitable fastening elements pass. As shown in FIG. 1, the mounting rail 26 can be fastened to the post profile within a large angular range by a specific fastening of the fastening bracket 28 . This angular range is only limited by the fact that the facade panels, not shown in Fig. 1, must be brought to a watertight and firm connection on both sides of the post.

The receiving rails 26 are shaped so that their ends lie closely on the one hand on the arcuate region 20 of the post profile, on the other hand end between the mounting bracket 28 and the arcuate region and are thus fixed in position. In addition, the receiving rails 26 are formed with a longitudinally extending groove into which a sealing element 30 can be inserted.

The sealing elements 30 each have a fastening foot 32 , which extends as a web-shaped design in the longitudinal direction of the strip-shaped sealing element and can be inserted into the correspondingly designed groove of the receiving rail 26 . By clamping the fastening foot 32 into the groove of the mounting rails 26 , the sealing elements 30 are adequately fastened to the mounting rails because in the assembled state, the pressure acting on the sealing element 30 from the facade plate prevents it from slipping out of the mounting rail 26 . On the side facing the glass pane or facade panel, the sealing elements 30 are provided with longitudinal grooves. Furthermore, the sealing elements 30 are provided with a drainage extension 34 , which ends in a fastening lug 36 . The fastening lug 36 can be inserted or pushed into a correspondingly shaped groove 38 which is formed on the spacer strip 24 and runs in the longitudinal direction.

As shown in FIG. 1, the drainage extension 34 forms a drainage channel 40 , the depth of which depends on the angular position of the receiving rail 26 on the post profile 12 . The greater the angle between the receiving rail 26 and the post profile 12 , represented by the angle between the axis 14 and the fastening axis of the fastening element between the arcuate region 20 and the receiving rail 26 , the smaller the depth of the drainage channel 40 , as is clear from FIG. 1 becomes. The depth of the drainage channel is to be understood here as its extension in the direction of the rear side 16 of the post profile 12 . In order to allow the targeted removal of the liquid transported along the rungs at all possible angular positions of the receiving rail 26 on the post profile, the drainage channel must be deep enough to reach behind the drainage channels formed along the rungs and the penetration of moisture to prevent safely inside the building.

The sealing elements 30 have tear-out slots 42 , along which in a convenient manner, for. B. only using a knife, the sealing elements 30 can be divided. This creates a division along the division plane 44 , so that with an appropriate division of the sealing elements running along a rung profile and post profile, an overlapping connection between the sealing strips can be produced.

Fig. 2 shows a vertical section through a post-rung construction 10 of the present invention. All elements already shown in FIG. 1 and explained on the basis of the description of FIG. 1 are denoted by the same reference numerals in FIG. 2.

In FIG. 2, facade panels 54, fixed, for example glass plates, at the rung 50th For this purpose, a spacer bar 24 already shown in FIG. 1 is first pushed over a central groove 56 of the rung 50 in such a way that two legs of the spacer bar 24 made of plastic on the webs between the groove 56 and the adjacent grooves 58 on the groove 56 close-fitting side. The spacer bar 24 has grooves 38 which run in the longitudinal direction and which in the installed position open upwards and downwards and serve for the clamping or form-fitting insertion of sealing elements 52 in the form of elongated sealing strips. The sealing elements 52 are inserted on the one hand in the grooves 60 of the profile 50 and on the other hand engage in the grooves 38 of the spacer strip 24 . In this way, on the one hand, a sealing connection is produced along the side of the rung 50 directed towards the outside of the building, and on the other hand, the spacer strip 24 which is merely plugged onto the rung 50 is fixed in position. Finally, the groove 58 of the rung is sealed against moisture penetrating from outside. As a result, those areas in which there are bores in the closed profile of the rung 50 , for example in the area of rung connectors arranged in the grooves 58 between rung and post, are sealed by the sealing element 52 and no additional sealing measure is required for those in FIG. 6 Fasteners shown between rung 50 and post 12th

The sealing element 52 is formed on the side facing the facade panel 54 as a labyrinth seal and additionally has longitudinal slots 42 , which allow the seal 52 to be easily cut along the line 44 shown in broken lines. As a result, an overlapping arrangement of the sealing elements running along the rung and the sealing elements running along the post can be formed in the joint region between rung 50 and post 12 , as will be explained in more detail later. The facade shown in FIG. 2 is closed to the outside by a preferably multi-part cover strip 66 which runs in the longitudinal direction of the rung 50 . The multi-part cover strip 66 shown in FIG. 2 consists of a first profile strip 74 , which on the one hand serves to receive strip-shaped sealing elements 78 , and on the other hand also has a plurality of bores along its course which serve to receive a fastening element which passes through the spacer strip 24 and is fastened in the central groove 56 . In order to achieve a seal in the area of the fastening elements (not shown) and also to be able to individually design the visual appearance of the facade construction, a second profile strip 76 , which together with the first profile strip 74 forms the cover strip 66, is fastened in a suitable manner on the first profile strip.

The attachment of the façade panels 54 is done on one hand by the clamping contact between the sealing elements 52 and 78, on the other hand, by resting on a supporting member 80 comprising a support to providing on each rung 50 of the of the respective rung upwardly extending facade panel 54th The occurring load is transmitted to the support element 80 via the spacer bar 24 arranged therebetween and, in some areas, the sealing element 52 arranged therebetween to several fastening elements 82 arranged along the rung 50 , which pass through the spacer bar through suitable bores and in the central groove 56 of the rung 50 can be fixed.

The rung 50 shown in FIG. 2 can already be largely preassembled by the sealing elements 40 already being arranged in the grooves 60 and engaging in the grooves 38 of the spacer strip 24 which is likewise attached to the rung 50 . In this way, a fixation of the spacer bar 24 is already achieved. Furthermore, the fastening elements 82 can also be inserted into the central grooves 56 at predetermined intervals.

In the case of the rung profile shown in FIG. 2, unlike the mullion profile shown in FIG. 1, the facade panels 54 cannot be brought at an angle to one another. It should be noted at this point, however, that a rung profile, which is shaped in accordance with the post profile shown in Fig. 1 and allows the attachment of facade panels so that they come to lie in one plane, can be used in the same way in the rung area .

Fig. 3 shows a horizontal section through the post-rung construction on a post that is not arranged in the area of a kink in the facade. Here, too, a post could be used in the same way, which has the profile shown in FIG. 1. All components which are correspondingly shaped to in Fig. 2 shown to be provided with the same reference numerals, even if the components illustrated in Fig. 2 and Fig. 3 are not identical, as it is in Figs. 2 and 3 for cross-sectional views acts, which are carried out once in the vertical direction and once in the horizontal direction.

In the same way as explained above in connection with FIG. 2, a spacer bar 24 and a cover bar 66 consisting of a first profile bar 74 and a second profile bar 76 are pushed or fastened onto the post 12 shown in FIG. 3. The sealing elements 78 shown in FIG. 3 are also identical in construction to the sealing strips 78 shown in FIG. 2 and extending in the horizontal direction. The facade panels 54 are fixed in position on the post 12 running in the vertical direction only by the clamping installation between the sealing elements 84 and 78 .

The sealing elements which are inserted into the first grooves 60 of the post 12 and in turn inserted into a groove 38 of the spacer strip 24 differ from those shown in FIG. 2. The sealing elements 84 running along the vertical posts are designed with a view to the targeted removal of the steam or liquid that has penetrated from the outside of the building or condenses in the facade area.

Comparing the design of the sealing elements 52 and 84 in FIGS. 2 and 3, it is clear that the sealing elements 52 and 84 have a different shape. While the sealing elements 84 running along the post 12 have a pronounced drainage channel 86 , the corresponding drainage channel 88 of the seal 52 along the rung 50 is only very weakly pronounced. This means that the drainage channel 86 extends deeply into the second grooves 58 along the post, while the sealing elements 52 along the rungs have only a very slight drainage channel 88 .

In the joint area between rung 50 and post 12 , both the sealing elements 52 along the rung and the sealing elements 84 along the post are divided along the longitudinal slot 44 (see FIG. 2), and then arranged to overlap. Here, the upper halves of the sealing elements are placed along the rungs, ie the halves facing the facade panel 54 and the exterior of the building, overlapping the lower halves of the seals 84 along the post. This design of the seals creates a liquid- and vapor-tight connection between the rung and the post. The water accumulated in the essentially horizontal drainage channel 88 of the sealing element 52 is fed in the joint area between the rung and the post into the, as described above, much more bulged, vertically extending drainage channels 86 of the sealing element 84 and is conveyed downward. This creates a liquid- and vapor-tight barrier, which is additionally supported by the fastening of the sealing elements 52 and 84 on the spacer strips 24 .

An advantage of the design of the sealing elements shown is in that fasteners, not shown, between Rungs and posts behind the liquid and vapor tight Barrier can be arranged and therefore no separate Sealing measures in the mullion-rung connection area are necessary.  

Another advantage of the illustrated design of the sealing elements 52 and 84 is that a continuous shield is formed along the front of the rungs and posts, which is formed by the sealing elements and the spacer bar. As a result, heat losses due to heat radiation between the cover strip 66 and the posts as well as rungs can be significantly reduced. The fastening elements 82 for supporting the facade panels also do not allow an opening to be created in the hollow profile of the rungs, since the fastening elements are preferably screwed into the middle, third groove 56 , it being possible to use a self-tapping fastening element which does not reach the bottom of the middle, third groove 56 .

FIG. 4 shows a horizontal section through the facade construction in a buckling area. As can be seen from FIG. 4, the two facade panels 54 are arranged at an angle to one another. The angle α can move between 90 ° and 180 ° depending on the attachment of the mounting rails 26 to the arcuate regions 20 of the post profile 12 .

As was already described above in the explanation of FIG. 1, sealing elements 30 are inserted into the mounting rails 26 , which are fastened to the arcuate regions 20 by means of a suitable fastening element, each of which has a drainage attachment with a fastening lug 36 formed thereon. The fastening lugs 36 are each inserted into the correspondingly shaped fastening grooves 38 of the spacer bar 24 , which in turn is pushed onto the post 12 .

The facade panels 54 each rest on the sealing elements 30 , these being supported in a suitable manner, for example by support elements, on the horizontal rungs. The facade panels 54 are held from the outside of the facade by the sealing strips 62 , the fastening foot 64 of which can be inserted or inserted into a correspondingly shaped receiving groove in a cover strip 66 . The cover strip 66 is with suitable fasteners, for. B. screws, attached to the post 12 , which engage through the spacer bar 24 in the receptacle 22 of the post.

In order to be able to set any angle α in the predetermined range from 90 ° to 180 ° with the cover strip, this has an edge 68 , along which the cover strip 66 is bent to the desired angle. The cover strip 66 can, as in the example shown, consist of two sections which overlap one another in the region of the fastening elements, and are preferably roll-formed from sheet metal. In the area of the fastening elements which are inserted into the post 12 along the axis 70 , the cover strip 66 lies against the spacer strip 24 .

Finally, a facing strip 72 is placed or pushed over the cover strip 66 in order to give the facade the desired visual appearance.

Sealing elements 30 are also easily divisible in regions along dividing plane 44 , for example with the aid of a knife, and an overlapping connection can be made between sealing elements along an adjacent rung and sealing elements 62 along the post.

Comparing the design of the sealing elements in FIGS. 2, 3 and 4 shows that they are each designed differently, the depth of the drainage channels being different. The respective drainage channels are each shaped in such a way that the liquid that has penetrated or condensed out can be removed in a targeted manner. To achieve this, the drainage channels engage behind each other so that the liquid can be safely drained off. In addition, the drainage channels of the sealing elements 62 shown in FIG. 4 must be shaped in such a way that this function is retained even with any angular fastening of the mounting rail on the post profile.

Fig. 5 shows a detail of a further embodiment of a facade in the horizontally extending section in the region of a post. The components mentioned in the figures described above are designated by the same reference numerals in FIG. 5.

In Fig. 5, a tubular support post 90 is illustrated extending in vertical direction. As in the description above, the term vertical should not be understood in the strict sense, but rather should enable a distinction to be made between the horizontal parts of the facade. When creating pyramid-shaped or dome-shaped facades, the components referred to as vertical can of course be arranged at an angle to the vertical. On the tubular support post 90 , two posts 12 a and 12 b are attached, the angle β between the posts 12 a and 12 b being adjustable before they are attached. The posts 12 a and 12 b are formed in a similar manner to that shown in FIGS. 1 and 4 and each have arcuate regions 20 , along which the mounting rails 26 can be moved and fastened. The attachment can be done as explained in connection with FIG. 1.

Sealing elements 30 made of plastic are inserted or inserted into the receiving rails and these are attached to spacer strips 24 in the manner already described.

The facade panels 54 are held between the sealing elements 30 and 62 , wherein the sealing elements are each received in a profile strip 94 made of metal. The end to the outside of the facade forms a facing strip 96 , which has at least one buckling edge 98 , to be adapted to any angular arrangement of the posts 12 a and 12 b on the support post 90 , but also the receiving rails 26 on the posts 12 a and 12 b to be able to.

In this embodiment, a further sealing element 92 made of plastic is arranged between the spacer strips 24 plugged onto the posts 12 a and 12 b, the sealing element 92 likewise having fastening lugs 36 which can be inserted or inserted into the fastening grooves 38 running along the spacer strips.

Due to the formation of a kink area in the facade according to the embodiment according to FIG. 5, there is a further degree of freedom compared to the embodiment shown in FIG. 4, because both the posts 12 a and 12 b and the receiving rails 26 each on the posts 12 a and 12 b are independently adjustable.

The posts and rungs according to the invention can be used achieve a three-dimensional mullion-rung construction,  with any in a relatively large angular range Angles at the corners or kinks that occur can be set without separate components to have to use for this. The sealing elements can be so align that the filling elements, especially glass panes or facade panels, in a sealing manner between the sealing elements are held. At the same time, the Facade substructure through the formation of the Sealing elements against the ingress of liquid or steam sealed and targeted removal of the penetrated or condensed liquid achieved.
