Each rail can have a trough-shaped mounting surface shaped to fit against its respective mounting rib. The axes of the uprights and crossmembers can be situated symmetrically in relation to each other, and each can have a central mounting (22) at the front in which a distance-strip (24) is fixed.

Description

The invention relates to a mullion-rung construction, in particular for facades or roofs, for receiving flat filling elements, in particular glass panes or facade panels.

In the case of three-dimensional mullion-rung constructions, the mullions and rungs are not arranged in one plane, but there are kinks within the mullion-rung construction where the glass panes adjoining a post in the horizontal direction or adjoining a rung in the vertical direction or facade panels are at an angle to each other. Such three-dimensional mullion-rung constructions are often designed in the form of polygon facades or pyramids or domes.

The substructure of facades or roofs in the form of a mullion-rung construction has on the one hand the task of receiving and fixing the glass panes or facade panels; on the other hand, to drain away any liquid that has penetrated or condensed out and to ensure good ventilation of the facade. In order to meet all of these requirements, the technology usually uses tailor-made solutions, ie solutions that are tailored to special requirements Erection of three-dimensional facades or roofs with complex shapes significantly increase the manufacturing and assembly costs. For this reason, there is an urgent need for a three-dimensional mullion-bar construction which, in the manner of a kit system, provides a limited number of different elements with which three-dimensional mullion-bar constructions are built as a substructure for facades or roofs with a design that is as variable as possible can.

The invention is based on the technical problem of creating a mullion-rung construction which, with perfect water drainage, has a high degree of variability in terms of shape.

This technical problem is solved by a post-rung construction with the feature of claim 1.

In the solution according to the invention according to claim 1, the post-rung construction, which can be expanded to three-dimensional post-rung constructions, comprises posts designed as hollow profiles and / or rungs designed as hollow profiles on the one or more kinks of the post-rung construction, each with two arcuate fastening webs the posts and / or rungs, on each of which mounting rails for sealing elements can be attached continuously and at a predetermined angle to the other mounting rail.

As a result, any angle can be set in a relatively large angular range both on the posts and on the rungs and, at the same time, the sealing elements each aligned such that the filling elements, in particular glass panes or facade panels, are in the best possible way be sealed between the sealing elements. Due to the infinitely variable adjustment of a desired angle between adjacent filling elements, usually in the form of glass panes or facade panels, a high number of different system elements can be used to achieve a high degree of variability with regard to the design and shape of facades or roofs that can be achieved.

The receiving rails for sealing elements preferably have a channel-shaped contact surface which is shaped corresponding to the arcuate fastening webs. This offers the advantage that a large contact area is formed between the receiving rails and the arcuate fastening webs on the post and / or the rung in order to transmit the forces that occur to the posts and / or rungs.

According to a preferred embodiment, the posts and rungs are axially symmetrical. An axially symmetrical design offers the advantage that both the two filling elements attached to a post or a rung, but also only one of the two filling elements, can be attached at a predetermined angle. This means, for example, that the installation direction in the area between a flat facade and an inclined roof surface is irrelevant, because the desired angular arrangement of the facade panel in the transition to the roof area can be fastened on both sides of the axially symmetrical rung.

The posts and rungs preferably have a centrally arranged receptacle on the front for fastening a spacer bar. The front side is understood to mean the side of the rung and the post pointing towards the outside of the facade. The attachment of a spacer bar is important, because on this one on the Facade outside, ie arranged outside the filler elements, can be fastened, which, in turn provided with seals, seals the filler elements from the outside of the facade against the ingress of moisture and holds the filler element.

The spacer bar preferably has fastening grooves into which associated fastening elements of the sealing elements engage. In this way, the spacer bar can be attached to the post or to the rung; on the other hand, a continuous, liquid-tight barrier can be created along the front of the post or rung. Finally, this liquid- and vapor-tight barrier serves to shield unwanted heat radiation between the outside and inside of the facade.

According to a preferred embodiment, the sealing elements are each strip-shaped and have tear-out slots along which the sealing elements can be divided. This means that on-site, i.e. on the construction site, an overlapping connection between the sealing elements along the rungs and the sealing elements along the posts in the joint area between the posts and rung can be produced in a simple manner.

Preferably, the sealing elements overlap along the rung and the sealing elements along the post so that the sealing element is arranged along the rung to the outside of the facade or the roof. As a result, the water that has penetrated behind the facade panel or the liquid that has condensed out in this area can be transferred specifically into the vertically arranged drainage ducts along the posts.

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 the abutment area between the post and rung reaching behind the drainage channels of the sealing elements along the rung. This formation of mutually interlocking drainage channels allows the penetrated or condensed liquid to be drained off in a targeted manner, since the drainage channels along the posts can completely absorb the liquid transported from the drainage channels along the rungs and remove them in a targeted manner.

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

The invention is described below purely by way of example with reference to the accompanying drawings, in which:

Fig. 5

shows a further embodiment of a facade in 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. 1, which is 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 made of metal, in particular steel, and can be rolled in the longitudinal direction of the post 12, ie perpendicular to the plane of the drawing in FIG. 1 Slide onto mounting bracket 28. 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. Due to the clamping insertion of the fastening foot 32 into the groove of the mounting rails 26, the sealing elements 30 are adequately attached to the Mounting rails attached 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 the sealing elements 30 can be divided in a convenient manner, for example only using a knife. Here there is a division along the division plane 44, whereby an overlapping connection between the sealing strips can be produced with a corresponding division of the sealing elements running along a rung profile and post profile.

Figure 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.

2, facade panels 54, for example glass panels, are attached to the rung 50. 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 into the grooves 60 of the profile 50 and on the other hand engage in the grooves 38 of the spacer strip 24. This on the one hand creates a sealing connection along the side of the rung 50 directed towards the outside of the building, and on the other hand it is only attached to the rung 50 Spacer bar 24 fixed in position. Finally, the groove 58 of the rung is sealed against moisture penetrating from outside. As a result, there are those areas in which there are bores in the closed profile of the rung 50, for example in the area of the grooves 58 Rung connectors between rung and post, sealed by sealing element 52 and no additional sealing measure is required for the fastening elements between rung 50 and post 12, not shown in FIG. 6.

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 facade panels 54 are attached on the one hand by the clamping contact between the sealing elements 52 and 78, on the other hand by resting on a support element 80, which provides on each rung 50 a support for the facade panel 54 extending upward from the rung in question. 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 a plurality of fastening elements 82 arranged along the rung 50, which pass through suitable holes through the spacer bar 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 shaped corresponding to those shown in Fig. 2 are provided with the same reference numerals, even if the components shown in Fig. 2 and Fig. 3 are not identical, since it is in Figs. 2 and 3 are sectional views that 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 identical in construction to the sealing strips 78 shown in FIG. 2 and run in the horizontal direction. The facade panels 54 are fixed in position on the post 12 extending 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 is along the seal 52 the rung 50 is very weak. 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 along the rungs, i.e. the halves facing the facade panel 54 and the building exterior are placed overlapping over 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 that fastening elements, not shown, can be arranged between the rung and the post behind the liquid- and vapor-tight barrier, and therefore no separate sealing measures are necessary in the post-rung connecting area.

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 fitted with suitable fastening elements, e.g. Screws attached to the post 12, which engage through the spacer 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.

5 shows a section of a further embodiment of a facade in a horizontal section in the area of a post. The components mentioned in the figures described above are designated by the same reference numerals in FIG. 5.

5, a tubular support post 90 is shown, which extends in the 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. Two posts 12a and 12b are attached to the tubular support post 90, the angle β between the posts 12a and 12b being adjustable prior to their attachment. The posts 12a and 12b 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 is formed by a facing strip 96, which has at least one folding edge 98, in order to be able to be adapted to any angular arrangement of the posts 12a and 12b on the support post 90, but also the receiving rails 26, in each case on the posts 12a and 12b.

In this embodiment, a further sealing element 92 made of plastic is arranged between the spacer strips 24 plugged onto the posts 12a and 12b, 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.

5, there is a further degree of freedom compared to the embodiment shown in FIG. 4, because both the posts 12a and 12b and the mounting rails 26 each independently on the posts 12a and 12b are designed adjustable in angle.

With the posts and rungs according to the invention, a three-dimensional post-rung construction can be achieved, in which any angles can be set at the corners or kinks occurring in a relatively large angular range without having to use separate components for this. The sealing elements can be aligned so that the filling elements, in particular glass panes or facade panels, are held in a sealing manner between the sealing elements. At the same time, the facade substructure is sealed against the penetration of liquid or steam by the design of the sealing elements and a targeted removal of the liquid which has penetrated or condensed out is achieved.
