Description

The invention relates to a mullion-transom connection according to the preamble of claim 1.

Facades for house walls are often constructed by means of so-called posts and bars, which carry facade elements such as glasses. The posts and bars are designed as elongated support members, the posts are each perpendicular and the bars are arranged horizontally. To connect the vertical posts with the horizontal bars and thus to enable a stable facade structure, post-and-beam connections are provided. Often, such a mullion-and-transom connection is formed such that a longitudinal end of a latch at a particular vertical position is connected to a post in the form of a T-joint. For such post-and-beam connections, a variety of connection types are known.

From the EP 1 548 200 is a mullion-transom facade known with a generic mullion-transom connection. In order to enable a pre-assembly and a simple production, in particular the bolt, a connecting part is attached to the post in the desired position and a locking part is fastened to a longitudinal end of the bolt, wherein the connecting part and the locking part are designed for a mutual holding engagement. This makes it possible to use standardized components for the post and the bolt, such as drawn metal profiles or beams made of wood, and to shorten these as needed to the desired length. Thus, the various architectural requirements can be very variably addressed. After the attachment of the connecting part to the post and the latch member on the bolt, the bolt can then be attached to the already mounted post, wherein means are provided to clamp the bolt against the post and to fix them together so gap-free.

From the DE 20 2006 008 511 It is also known to provide on the connecting part a horizontally extending web and on the latch part a web receiving groove in order to achieve a stable connection between the connecting part and the latch part.

Out EP 1 548 200 A2 is also known to arrange at a free end of the web a compression, which is designed for an undercut positive engagement in a arranged in the bottom of the groove corresponding recess.

In many cases, however, the problem arises that in the alignment of the post marginal tolerances occur, so that the distance between the posts varies slightly with each other. As a result, the assembly of the known mullion and transom connections is made more difficult, as it can lead to tension between the bolt and the post and, if necessary, elaborate reworking and adjustments are required.

The object of the invention is therefore to enable a mullion and transom connection for a facade, which allows a simple connection of posts and bars especially with larger tolerances in the construction of the facade.

This object is achieved with the features of claim 1. Advantageous embodiments are specified in the subclaims.

In the mullion-transom connection, a thickening is arranged at a free end of the web, which is designed for an undercut positive engagement in a arranged in the bottom of the groove corresponding recess, whereby a positive connection between the latch member and the connecting part and also a separate horizontal bracing of the two parts in the horizontal direction is possible. In addition, a gap is formed between a vertical contact surface of the thickening and a vertical contact surface of the recess, whereby a horizontal clamping between the bolt and the post will facilitate. An inserted into this gap clamping element can initiate the force for pressing the bolt against the post in the vertical contact surfaces at the desired location. In addition, the latch part comprises a separate support device, whereby a positioning of the latch member relative to the latch in the vertical direction is made possible. Separately this means a spatially separated, so multi-piece design, so that the support device can be easily replaced. This is particularly advantageous, as this bolt can be stored with different inner dimensions by the choice of the support device with the appropriate dimensions backlash on the bolt part. The support device is in a storage in the latch part with two in each case in the opposite direction against the bolt arranged acting support elements, wherein the pointing in the opposite direction supporting elements act in these directions against the bolt. The support device may include two threaded portions with opposite thread pitch, which cooperate with corresponding threaded portions in the support elements, each support element is associated with a respective threaded portion with opposite thread pitch. Upon rotation of the threaded portions, the support members are moved vertically in the opposite direction and pressed evenly against the latch, so that there is a centering of the bolt with respect to the latch member. As a result, tolerances of the inner dimensions of the bolt, the wall thickness of the bolt and different cross-sectional shapes of the bolt can be compensated.

Between opposing vertical contact surfaces on the thickening and the recess clamping elements may be arranged, which are designed as clamping screws with conical clamping areas, as thread-cutting or thread-forming screws or the like. By means of these clamping elements, the vertical contact surfaces on the thickening and the recess can be pressed in opposite directions and thus the bolt can be acted upon against the post.

In a preferred embodiment, the gap may preferably be designed conically or with a section-wise cross-sectional change. As a result, the force of the clamping elements can be adapted to the thickening and the recess and thus the force between the bolt and the posts depending on the conical or generally in cross-section changing course of the gap.

In addition, either on the web or the groove, a horizontal contact surface for an inserted in a gap between the web and the groove and equally formed in the web and the groove positively engaging fixing element may be formed. The fixing element is thus arranged at least partially in the gap and is for mutual vertical fixation of bolt part and connecting part equally with the horizontal web and the groove in positive engagement. At the web or the groove, the fixing element acts in a form-fitting manner with the horizontal contact surface.

In an advantageous embodiment, the horizontal web has a constant thickness and parallel horizontal contact surfaces. Likewise, the groove preferably has a plurality of each other opposite horizontal contact surfaces, so that between the contact surfaces on the groove and the contact surfaces of the web, a horizontal gap is formed with a constant gap.

Preferably, the width of the gap in the longitudinal direction of the bolt is greater than the width of the fixing element in the gap. If the fixing element is not arranged completely in the gap, the width of the fixing element is to be understood as the width of the part of the fixing element which is arranged in the gap. Characterized in that the gap in the longitudinal direction of the bolt has a greater width than the width of the fixing element in the gap, it is ensured that the fixing element is engaged only with the horizontal web and the vertically opposite groove and the horizontal web with respect to the groove the fixing element is not clamped in the horizontal direction. The web and the groove are preferably aligned horizontally, that is they have corresponding horizontal side surfaces, so that there are also horizontal gaps between the web and the groove.

Preferably, a guide for the at least one fixing element can be formed in a side wall of the groove or in the web, whereby the assembly of the fixing element is facilitated and the fixing element is held in a positionally accurate manner on the groove or the web.

Particularly preferably, the guide for the fixing element is designed as a bore whose bore channel is open laterally to the horizontal gap between the web and the groove. Through this lateral opening in the drill channel, the fixing element can protrude and in operative contact, in particular positive engagement with the opposite component, ie the web or the groove and in particular the formed thereon horizontal contact surface occur. As a result, the web is reliably fixed relative to the groove, so that a relative movement in the horizontal and in particular in the vertical direction is prevented. Depending on the design of the fixing element, the bore is to be positioned so close to the groove or within the web that, during assembly of the fixing element in the laterally open bore, the fixing element comes into contact with the opposite contact surface on the web or groove and interacting with it. The bore can have different geometries, which have in common that thereby the fixing can be positioned and preferably also held. This can advantageously be achieved in that the laterally open bore surrounds the fixing more than half.

In an advantageous embodiment, the fixing element may be formed as a thread-cutting or thread-forming screw. Such a screw can be mounted into a bore or gap without upstream threading because the threads of the threading screw are configured to self-tread the thread into the workpiece itself. With such a thread-cutting or thread-forming screw as fixing a particularly time-saving and stable fixation of the web can be done relative to the groove.

In each case a gap may be provided in the vertical direction above and below the horizontally extending web to sidewalls of the groove, in each of which a fixing element is arranged. As a result, particularly large vertical tolerances can be compensated.

In a preferred embodiment, the horizontally extending web is provided on the connecting part and the corresponding groove is provided on the locking part. In this case, the connecting part by means of screws to the post and the latch member may be secured by means of further screws to the bolt. However, the web can also be arranged on the latch part and the corresponding groove on the connecting part.

In a particularly advantageous embodiment, the latch member may be inserted into an interior in the latch. This interior can be formed for example by a hollow-walled design of the bolt as an extruded profile, but also as a cutout. In this case, the latch member may in particular be inserted so far into the interior of the bolt that the longitudinal end of the bolt protrudes outwardly relative to the latch member. As a result, the bolt can be braced directly against the post, resulting in a particularly stable and aesthetically pleasing connection of posts and bars.

In order to enable simple assembly, the latch on an outer side, which preferably corresponds to the outside of the facade, at the longitudinal end have a recess which corresponds at least to the outer dimensions of the cross section of the connecting part. As a result, a lateral horizontal pushing the latch member is made possible with the latch on the connecting part to the post. As a result, the bolt already on the connecting part of the post is provisionally held, there is a simple pre-assembly. In the event that a thickening at the connecting part at the free end of the web and a corresponding recess and / or a corresponding guide is provided at the bottom of the groove, the outer dimension of the recess of the bolt corresponds to at least the outer dimensions of the cross section of this connecting part to the lateral sliding and easy to assemble.

In order to stabilize the bolt in the region of the recess and in particular to stiffen an additional plate may be provided, which covers the recess and is secured to the latch. The additional plate is preferably fastened to at least two spaced fastening points with the latch member, for example by means of screws.

The support device may comprise a turntable with radial through bores whose axis Favor cuts the axis of rotation of the turntable. In the latch part, an additional bore is provided, which is designed to be aligned with one of the radially continuous bores of the turntable. As a result, for example, an inserted into the additional bore and at the same time in one of the radial bores of the turntable locking element prevent unintentional rotation of the turntable.

Favor can be formed by the support device, a depth stop for the connecting part. If the bolt is pushed onto the connecting part with the locking part, the supporting device, in particular the turntable, abuts against the connecting part and thereby reaches the exactly defined final depth position.

Instead of an adjustable threaded connection between the support device and the support elements, the support elements may also be formed as separate spacers, which are arranged on the latch part. Depending on the internal dimensions of the bolt used then support elements can be used with the appropriate size to allow centering and positioning of the latch member in the respective bar. With the supporting device or the supporting elements so that the bolt part is particularly easy against the bolt supported and braced. The term support device or support element is thus synonymous with the term tensioning device or clamping element and is used synonymously below.

In addition, a bolt member for the mullion-transom connection is claimed, which may be carried out as described.

a plan view of parts of the mullion-transom connection.

In FIG. 1 a mullion-transom connection 1 is shown in the form of a T-connection, by which a vertical post 2 is connected to a horizontal latch 3 to form a mullion-transom façade. For this purpose, a connecting part 4 is provided on the post 2, which cooperates with a locking part 6 arranged on a longitudinal end 5 of the bolt 3. The connecting part 4 has a horizontal web 7 with a constant thickness and horizontal side walls. At the latch member 6, a horizontal groove 8 is provided, which surrounds the web 7 on both sides and also has horizontal side surfaces. The wall thickness of the web 7 is in the vertical direction so less than the width of the groove that above and below the web 7 each have a constant horizontal gap 9, 10 is provided between the web 7 and the groove 8. Since the mullion-transom connection 1 is formed symmetrically to a horizontal center plane, not all symmetrically arranged further components are numbered in the figures to be clear.

Through each gap 9, 10 a movement of the latch member 6 is facilitated relative to the connecting part 4, whereby the assembly is simplified. In addition, it is ensured by the horizontal groove 8 and the horizontal web 7, that even with a mutual horizontal displacement of groove 8 to web 7, an overlap region 11 (marked in FIG FIG. 2 ) is present, in which the horizontal web 7 of the horizontal groove 8 in the vertical direction opposite and thus the two columns 9, 10 with a constant gap D and a Slit width B are formed. The height of the web 7 and the corresponding depth of the groove 8 correspond to a multiple of the gap D of the horizontal columns 9, 10th

In each of the horizontal columns 9, 10, a fixing element 12,13 is provided in each case, which stands for mutual vertical fixation of bolt part 6 and connecting part 4 equally with the horizontal groove 8 and the horizontal web 7 in positive engagement. The width C of the fixing elements 12, 13 in the horizontal columns 9, 10 is less than the gap width B of the columns 9, 10 in the longitudinal direction of the bolt 3, which corresponds to the width of the overlap region 11.

The fixing elements 12, 13 are formed as thread-cutting or thread-forming screws, which when screwing into the gap, the necessary thread in the web 7 and the groove 8 itself cut or furrow. The fact that the height of the web 7 and the corresponding depth of the groove 8 correspond to a multiple of the gap D of the horizontal columns 9, 10, the web 7 can be moved horizontally relative to the groove 8 and in each position a mutual fixation of web. 7 and groove 8 by means of the inserted into the columns 9, 10 fixing elements 12, 13 done. Since the width C of the fixing elements 12, 13 in the horizontal columns 9, 10 is also less than the width B of the horizontal columns 9, 10, the vertical web 7 and the horizontal groove 8 by the fixing elements 12, 13 only in the vertical direction clamped in the form of a height fixation against each other and fixed. Since it often happens in the installation of post-and-beam facades that the distance of the pre-assembled post slightly different, this can be particularly advantageous tolerance compensation of the length of the bolt 3 and thus a stable connection of post 2 and 3 bar can be achieved.

In order to achieve an easier assembly of the fixing elements 12, 13, a guide in the form of holes 14 in the latch part 6 is provided. The bores 14 are arranged in the locking part 6 in such a way that the bore channel of the bores 14 is open laterally to the respective horizontal gap 9, 10 between the web 7 and the groove 8. A fixing element 12, 13 inserted into the bore 14 protrudes laterally out of the bore 14 into the gap 9, 10 and, due to the thread-cutting thread connection, acts in a form-locking and non-positively locking manner both with the locking part 6 and with the web 7. The bore 14 is formed in the majority in the latch member 6, that is, that the lateral opening of the bore of the bore 14 has a smaller Width has as the diameter of the bore and the center line of the bore in the latch member 6 is located. As a result, the thread-cutting or thread-forming screws, formed fixing elements 12, 13 are positively held in the latch member and a quick assembly due to the guidance of the screws through the holes 14 is ensured.

The horizontal web 7 has two opposing horizontal contact surfaces 15, 16, which are designed for the positive engagement of the fixing elements 12, 13. Through these horizontal contact surfaces 15, 16 it is achieved that the gaps 9, 10 between the locking part 7 and in particular the there arranged in the holes 14 fixing elements 12, 13 and the web 7 even with a mutual horizontal displacement of bolt part 6 to web 7 a constant gap D has. This ensures that the fixing elements 12, 13 in each horizontal relative position of latch member 6 to web 7 in both the holes 14 and the contact surfaces 15, 16 positively engage and thus a height fixation of the bolt 3 to the post 2 despite any differences in length of the bolt 3 or different distances of the posts 2 can be done to each other.

At a free end of the horizontal web 7, a thickening 17 is arranged, which engages undercutting positively in a formed in the bottom of the horizontal groove 8 corresponding recess 18. As a result, a positive connection between the connecting part 4 and the latch member 6 is achieved in the longitudinal direction of the bolt 3. Between opposing vertical contact surfaces on the thickening 17 and the recess 18 in the latch member 6 clamping elements 19 are arranged, which are designed as clamping screws with conical clamping areas, as thread-cutting or thread-forming screws or the like. By these clamping elements 19, the vertical contact surfaces are pressed against the thickening 17 and the recess 18 in opposite directions and thus the latch 3 is acted upon against the post 2.

The latch member 6 is pushed so far into an inner space 20 of the formed as a hollow profile made of steel bolt 3, that the longitudinal end 5 of the bolt 3 projects relative to the latch member 6 to the outside. This ensures that in a mutual horizontal clamping of connecting part 4 and latch member 6 by the clamping elements 19th the bolt 3 is pressed against the post 2 and rests directly on this, resulting in a visually appealing construction.

The connecting part 4 is connected by means of screws 21 to the post 2, wherein the connecting part 4 is dimensioned with the screws 21 so that it can be completely received in the interior 20 of the bolt 3. The latch member 6 is connected to the bolt 3 with further screws 22.

The latch 3 has on an outer side at the longitudinal end 5 a recess 23, which is formed larger than the connecting part 4 in cross section. Thus, the latch 3 together with the latch member 6 secured therein in FIG. 1 be pushed vertically to the image plane on the connecting part 4.

Again FIG. 1 can be seen, the components of the mullion-transom connection 1 are formed symmetrically to a horizontal center plane of the bolt 3 and arranged. In this way, this post-and-bolt connection can be mounted independently of side on each end of the bolt 3, whereby the number of required parts is reduced and the assembly and storage is simplified.

In FIG. 2 is the mullion-tie connection 1 off FIG. 1 shown in a detail view. As can be seen from the detail view, a gap 9, 10 with a gap dimension D to the horizontal groove 8 in the latch part 6 is arranged above and below the horizontal web 7. In the bore 14 formed as a guide each fixing element 12, 13 is used, which is designed as a thread-cutting or thread-forming screw and by the threaded connection both with the bore 14 of the latch member 6 and the horizontal web 7 of the connecting part 4 in positive and non-positive Intervention is. Each fixing element 12, 13 protrudes through an opening arranged laterally in the bore 14 into the respective horizontal gap 9, 10.

The width C of the part of the fixing element 12, 13, which is arranged in the respective gap 9, 10, is less than the width B of the columns 9, 10 in the horizontal direction along the longitudinal axis of the bolt 3. By this ratio of the width C the fixing element 12, 13 in the respective gap 9, 10 and the width B of the columns 9, 10 - which also corresponds to the region 11 in which the web 7 and the groove 8 overlap in the vertical direction - it is ensured that the web 7 relative to the groove 8 can be moved horizontally in the direction of the longitudinal axis of the bolt 3 and also in this new relative positioning a stable vertical fixation of web 7 to groove 8 by the fixing elements 12, 13 is made possible. In this way, especially with a small lateral offset between the web 7 and the groove 8, an assembly of such bolt on the post, especially with tolerances in the distances between the posts to each other, easier. By fixing elements 12, 13 in the form of thread-cutting or thread-forming screws results in both an exact height fixation of the bolt 3 and a non-positive and positive connection between the post and bolt. Characterized in that the width B of the columns 9, 10 in the longitudinal direction of the bolt 3 is greater than the width C of the fixing elements 12, 13 in the columns 9, 10 ensures that the fixing elements 12, 13 only with the mutually vertically opposed horizontal Contact surfaces 15, 16 of web 7 and the holes 14 of the groove 8 come into contact and thus no lateral tension in the horizontal direction, but only a vertical height fixation takes place.

In FIG. 3 is the mullion-tie connection 1 off FIG. 1 shown in an exploded view. As can be seen, the horizontal web 7 of the connecting part 4 has a constant wall thickness, so that the in FIG. 1 designated columns 9, 10 regardless of the relative horizontal position of connecting part 4 and latch part 6 always have the same gap dimension D. The connecting part 4 is preferably formed as an extruded profile.

Also is in FIG. 3 the interior 20 of the formed as a hollow profile bolt 3, in which the latch member 6 is used. The latch member 6 is then firmly connected by means of the screws shown by the mounting holes shown with the latch 3. During assembly, the bolt 3 is pushed with the screwed-in latch part 6 horizontally in the direction of the arrow X from an inner side to the connecting part 4. After pushing the latch member 6 on the connecting part 4, the fixing elements 12, 13 are screwed into the holes 14, wherein the thread-cutting or thread-forming screws in both the bore 14 and in the contact surfaces 15, 16 of the web 7 cut a thread and thus brace the web 7 against the latch part 6 and fix it in height. Subsequently, the lateral recess 23 of the bolt 3 is closed by an additional plate 24 and connected by means of several screws, the additional plate 24 with the latch member 6 and the connecting part 4. By this stabilization and support of the latch member 6 by the additional plate 24 can be a widening or bending of the post 2 towards open latch member 6 can be prevented. The additional plate 24 produces a flat surface of the bolt plane. It can be horizontal forces against the direction of the arrow X from the bolt 3 in the post 2 abolish.

In addition, a bearing 25 for a tensioning device 26 is formed in the locking part 6. The tensioning device 26 has two opposite clamping elements 27, 28 in the form of rectangular blocks, which are connected by means of a threaded connection with a threaded rod 29. The threaded rod 29 has centrally arranged a rotary disk 30 with radial bores 31 distributed on the circumference. In these bores 31, a drive rod 32 can be used to drive the hub 30 in order to manually transmit a torque to the hub 30.

The threaded rod 29 is designed so that on both sides of the centrally located hub 30, the external thread has an opposite pitch, so that upon rotation of the hub 30 together with the threaded rod 29, the clamping elements 27, 28 move towards each other or away from each other. Characterized in that the bearing 25 in the outer region has a rectangular cross-section which is adapted to the clamping elements 27, 28, they are guided and co-rotation of the clamping elements 27, 28 prevented.

The bearing 25 has an additional bearing surface, not shown, for the hub 30, so that it is supported in the vertical direction via the latch member 6. During assembly, by means of the drive rod 32, the turntable 30 and thus the threaded rod 29 are rotated, whereby the clamping elements 27, 28 are clamped against the bolt 3. As a result, the different internal dimensions of the bolt height or tolerances, the wall thickness of the bolt and different bolt cross sections are compensated, so that a play-free system arises.

In FIG. 4 is a plan view of the latch member 6 shown together with the connecting part 4, wherein disposed within the latch member 6 elements are shown schematically by a dashed line. Again FIG. 4 can be seen, an additional bore 33 is disposed in the latch member 6, in which the drive rod 32 through the formed as through holes radial holes 31 of the hub 30 therethrough acts as a screw lock. For this purpose, the additional bore 33 is arranged in the latch member 6 so that the axis of the bore 33, the axis of rotation 34 of the hub 30 intersects. In the shown Embodiment, the additional bore 33 is also aligned in the longitudinal direction of the bolt 3. After clamping the clamping elements 27, 28 against the bolt 3 by rotating the hub 30 by means of the inserted into one of the radial bores 31 drive rod 32, the drive rod 32 can be inserted into that radial bore 31 which is aligned with the additional bore 33. In order to ensure that the drive rod 32 is in this retracted position with both the hub 30 and the additional bore 33 in contact and thus rotation of the hub 30 is prevented, the additional bore 33 may be formed as a blind hole whose depth is smaller As a result, the drive rod 32 is in the retracted position at a bottom 34 of the additional bore 33 and is still in engagement with one of the radial bores 31 of the hub 30th

By the turntable 30 also a depth stop for the connecting part 4 is generated. Like from the FIG. 4 can be seen, is the connecting part 4 in the inserted into the latch member 6 position on the hub 30, so that a defined mutual positioning is possible. During assembly, the locking part 6 is screwed in the bolt 3 and then the clamping element 26 is inserted into the groove 25. When pushing the bolt 3 with the latch member 6, the hub 30 abuts the connecting part 4 and thereby reaches the final depth position.

To adjust the contact pressure of the bolt 3 against the post 2, not shown, and in particular in a central to rear, in FIG. 4 Upper position in the latch member 6 to be able to generate by the clamping element 10, the gap 35 extends between the opposing vertical contact surfaces 36, 37 on the thickening 17 and the recess 18, between which the clamping elements 19 is arranged in FIG. 4 conically tapering towards the top. The vertical abutment surface 36 on the thickening 17 and the vertical abutment surface 37 on the recess 18 are also in FIG. 2 additionally designated. As a result of the conically tapering gap 35, the clamping element 19 only engages the gap 35 at the point at which the gap width corresponds to the width of the clamping element 19. As a result, it is also possible, in particular, to ensure a tensioning between the vertical contact surfaces 36, 37 despite different distances of the gap 35 due to assembly. As has already been stated, can be done with the described post-tie connection tolerance compensation during assembly, especially in the horizontal direction with respect to tolerances between the vertical post. Through the conical gap 35 can be achieved even with tolerances due to different distances between the vertical post reliable clamping of the bolt against the posts, then at a greater distance between the posts, the gap 35 is smaller overall and the clamping element 19 in an outer, in FIG. 4 shown lower portion of the gap 35 in contact with the vertical abutment surfaces 36, 37 occurs, while at a smaller distance between the posts, the gap 35 is greater overall and therefore the clamping member 19 only in a rear, in FIG. 4 shown upper portion of the gap 35 with the vertical abutment surfaces 36, 37 comes into contact. Optionally, the length of the example designed as a screw clamping member 19 during assembly to adjust accordingly to ensure a flush finish with the outside of the latch part.

The conical gap 35 can be made, for example, by cutting to length the bolt part 6 produced by the extrusion process by oblique cuts at the longitudinal ends 38, 39. Since the latch member 6 rests with these inclined sides 38, 39 on the latch 3 in the recess 20; the latch member 6 is thus rotated relative to the latch 3 by the angle of the oblique section. As a result, a recess 18 is achieved in a particularly simple manner, which runs obliquely, in particular at an angle deviating from 90 ° to the longitudinal direction of the bolt 3. Between the inclined vertical bearing surface 37 of the recess 18 and the in FIG. 4 However, it is also possible to achieve the conical gap 35 in the production by milling a corresponding obliquely extending recess 18.
