Description

The invention relates to a post-rung construction, especially for facades and roofs, to accommodate large areas Elements, in particular glass panes or facade panels, according to the preamble of claim 1.

A post-rung construction with notches on the The ends of the rung profiles are in German Published patent application DE 34 19 538. The rungs of the known construction are at their ends in the area behind the grooves on the edges of the front notched, d. H. with one, for example, by milling out provided recess provided. Thus lies the milled area of the rung ends on the side surface of the Post on the middle bar and on the edges grooves of the rung on the front face the post overlap its front. This overlap can Water that has formed on the front of the rungs and has entered the area in front of the front drain off the post and there along the vertical Posts are led downwards. Because of the overlap the rung ends with the edge areas of the front of the The grooves for receiving sealing strips lie in the posts along the rungs that run perpendicular to it Grooves for receiving sealing strips along the posts.  

This difference in position must be due to the shape the sealing strips are balanced, as these in the same level on the flat filling element, d. H. at the Glass pane or facade panel, come to rest.

With another mullion-rung construction for facades, as in the German patent DE 38 08 751 is proposed is the rung profile at its ends also notched up to the back of the on the Front surface of excellent central web, so that the grooves to accommodate the sealing strips of the rung on the Side surface of the post and only the middle web of the Shoot the edge of the front surface of the post overlaps. With this arrangement there is no distance compensation for the sealing strips required as the corresponding Grooves of rungs and posts at the same level lie, but a vertical edge remains between the side surface of the post and the end face of the groove of the adjacent rung. Through this vertical butt edge Water in the interior of the building behind the facade penetration.

The invention is based on the technical problem Post-rung construction to create a simple Connection of posts and rungs allowed, the corresponding grooves of the rungs and the posts for Inclusion of sealing strips are on the same level.

This technical problem is caused by a mullion-cone structure solved with the features of claim 1.

The posts designed as hollow profiles each have on its front side a plurality of grooves running along the Longitudinal extension of the posts, and also as  Hollow sections formed rungs each on their Front of a plurality of grooves along the The posts extend longitudinally. On the rungs is in the joint area to the posts in at least one of the grooves one rung connector in the longitudinal direction of the rung slidably guided and fixable on the rung attached. Part of the rung connector is in a Corresponding cross-sectional shape of the rung connector Insertable opening in the post, being between rungs and A straight butt joint is formed in the assembled state.

A straight joint is defined by the fact that both the Side wall of the post as well as the front of the rung lie together in a common plane. So it occurs no notches in the joint area.

By using the rung connectors that are in Longitudinal direction of the rung slidably guided and on the Rung can be attached, a connection be made between rungs and posts, where there is a straight joint between the rungs and the posts. By doing no notches or overlaps between rungs and Post, the corresponding grooves of the Rungs and the post to accommodate the sealing elements Arrange at the same level and neither is required complex shape of the sealing elements, another complex production of the front end areas of the Sprouts to make a simple connection between sprouts and To manufacture posts. Furthermore, the Construction of the post-rung construction according to the Features of claim I a whole series of Elements already in a pre-assembled state Promote the installation site. After all, can be flawed Cut rungs that are not between already arranged  Posts can be inserted through a simple, Bring the straight saw cut to the desired size.

Preferably, they are designed as hollow profiles Posts and rungs each have five grooves on their front, a central, third groove and axisymmetric to the central, third groove formed first grooves and second grooves, wherein the second grooves adjoin the central, third groove. As a result, the hollow profiles of the post and the Rung created a sufficient number of grooves to the to perform a variety of tasks for these components. To the one can be in two of the five grooves formed Sealing elements are used and attached. The above mentioned rung connectors along the rungs can be conveniently in the second grooves of the Arrange and fasten hollow profiles while the central groove the fastening of cover strips, which serves the facade lock to the outside, but also take up support elements can, which attach the facade panels.

The first grooves are preferably used for fastening Sealing elements. Since the first grooves each along the Side edges of the front of the post and rung run, it is recommended to use the sealing elements in this Area to attach to the entire muntin rung con design to be liquid and vapor tight.

According to a preferred embodiment, the strip-shaped sealing elements along the rungs and the strip-shaped sealing elements along the posts in each case 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 panels or the liquid condensed out in this area specifically in the vertically arranged drainage ducts along the posts convict.

According to a preferred embodiment, the central, third groove of the rung and over the central, third groove a spacer bar, the two has longitudinally extending fastening grooves.

Preferably, the sealing elements have along the rung like also the sealing elements along the post Fasteners on the in the fastening grooves of the intervene the assigned spacer bar.

By attaching a spacer bar in the longitudinal direction running fastening grooves as well as the engaged bring the sealing elements with the fastening grooves Spacer bar, can be a liquid and vapor tight Barrier along the front of the rungs and posts create what the fasteners between rung and posts in the form of rung connectors differ from the Building exterior viewed from behind the waterproof Barrier are located and therefore not sealed separately will need. Furthermore, the liquid and waterproof barrier also as a shielding surface that  Heat loss due to heat radiation between the outside of the building and reduce the inside of the building.

According to a preferred embodiment, the Sealing elements along the rung as well as the sealing elements along the post each have a drainage channel, whereby the drainage channel of the sealing elements along the post engage deeper in the second groove of the post than that Drainage channels of the sealing elements along the rung.

Due to this design, the second grooves have different distances protruding drainage channels can be targeted drain any liquid that has penetrated or condensed, by placing the drainage channels along the posts Reach behind drainage channels along the rungs and thus represent a "second level" which is derived from the Liquid transported to the rungs of the sprouts can record and deliberately remove.

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:

Figure 1 illustrates the attachment of a rung to a post;

. Fig. 2 and 3 each represent the configuration of a rung connector;

Fig. 4 shows a section along the line AA in Fig. 1;

Fig. 5 shows an enlarged section along the line BB in Fig. 1;

Figure 6 illustrates a vertical section through a post and rung construction; and

Fig. 7 shows a horizontal section through a post-rung construction.

Fig. 1 shows schematically the connection area between the post 12 and rung 14 of a post-rung construction, which is generally designated by reference number 10 .

The post 12 , of which only a section is shown, as well as the rung 14 are each, as is clear from the figures described below, designed as hollow profiles. The posts 12 and rungs 14 are preferably formed in one piece from rolled steel, each of which has a longitudinal seam, not shown, in a groove base, which results from the production from rolled steel.

The post-rung construction 10 shown in FIG. 1 is used in particular for facades or roofs, with flat filler elements, such as glass panes or facade panels, being placed on the substructure formed by the posts, rungs and sealing and fastening elements. Fig. 1 shows the design of the mullion-rung construction seen from the outside of the facade.

As will become clearer from the following figures, both the post 12 and the rung 14 have a series of grooves, which are each arranged symmetrically to the longitudinal axis of the post 12 or the rung 14 . Specifically, these are the grooves 12 a and 14 a for receiving and fastening sealing elements, 12 b and 14 b for receiving fastening elements and for forming drainage channels for penetrated or condensed water, and a central groove 12 c and 14 c for receiving fastening elements . While the bottom of the grooves 12 a, 12 b, 12 c and 14 a, 14 b, 14 c each lie on the same plane, the webs arranged between the respective grooves are of different heights.

Fig. 1 shows the attachment of the rung 14 on the post 12. For this purpose, a rung connector 16 is located in each of the grooves 14 b of the rung 14 , the shape of which is described in more detail below with reference to FIGS. 2 and 3. The rung connectors 16 are each provided with an elongated hole 18 and thus allow the rung connectors to be moved axially in the longitudinal direction of the rung 14 . After the desired axial displacement of the rung connectors 16 , they are fixed in position by means of a suitable fastening element 20 , for example a screw with an internal hexagon. As already stated above, both the post 12 and the rung 14 are a closed hollow profile, so that the end of the fastening element 20 inside the profile is not accessible or is very difficult to access from the end faces. The attachment of the rung connector 16 in the grooves 14 b will be described in detail later.

Fastening bolts 22 are arranged at the transom connectors 16 which engage in the fastening of the rung 14 on the post 12 in correspondingly shaped receiving apertures in the post 12th

The rung 14 lies flat against the post 12 , ie there are no shoulders or notches in the rung 14 or the post 12 . As a result, the rung 14 , which has been brought to the desired length, can be inserted from the front between two jambs 12 arranged next to one another and can be fastened to the jamb in the axial direction of the rung and in the direction of the jamb by moving the rung connector 16 .

Figs. 2 and 3 each show different views of the crossbar connector 16. The view shown in FIG. 2 corresponds to that shown in FIG. 1. The rung connector 16 is preferably formed from cast steel and then plasticized. While the length of the rung connector can be varied within a wide range, its width is matched to the width of the groove 14 b or the distance between the webs delimiting the groove 14 b. As a result, the rung connector 16 slides in the groove 14 b and no separate axial guidance is required. Small deviations are compensated for by the fact that the fastening bolt 22 has a slightly conical shape and thereby acts as a centering when entering the corresponding fastening hole in the post 12 . The elongated hole 18 has an axial length which, even when two fastening elements 20 (not shown) are used, permits the adjustment path required for fastening the rung to the post.

Fig. 3 shows another view of the rung connector 16 , it being clear that in the region of the elongated hole 18 of the rung connector 16 is narrower to prevent the sinking of one or more fasteners, for. B. in the form of fastening screws without the screw heads protruding over the rung connector 16 .

FIG. 4 shows a section along the line AA in FIG. 1. This section runs exactly in the parting plane between the post 12 and the rung 14 , that is to say between the front end of the rung 14 and the side wall of the post profile 12 . Due to the better clarification, however, the rung profile is shown with broken lines. From Fig. 4 it can be seen that the rung connectors arranged in the grooves 14 b of the rung 14 each pass through the fastening bolts 22 through a correspondingly shaped bore 26 in the post 12 . The end face of the rung 14 is, as stated above, on the flat side wall of the post 12 without the need for steps or notches on the post or on the rung. This allows the rungs in a simple manner, for. B. can be cut to a desired size by a sawing process. The spacer bar 28 , also shown in FIG. 4, will be described at a later point in time.

FIG. 5 shows a section along the line BB in FIG. 1. In the vertical section shown, the rung profile 14 and a web of the post 12 are again shown. In the grooves 14 b of the rung 14 , a rung connector 16 is attached. The fastening is carried out by means of a fastening element 20 , which in the case shown is an Allen screw. Any precaution 32 is preferably taken with the fastening element 20 such that it is captively connected to the rung 14 even in the loosened state. The grooves 14 b of the rung 14 are provided with a bore 30 through which the fastening elements 20 can be inserted into the rung 14 . A blind plug nut 24 with the internal thread matched to the fastening element 20 is then inserted from the outside into the rung profile 14 and is fixed in position when the fastening element is subsequently screwed in.

Due to the design of the fastening of the rung connector 16 in the groove 14 b shown in FIG. 5, this can be preassembled on the rung 14 before the mullion-rung construction is connected, the fastening elements 20 still being loosened and therefore shifting Allow rung connectors in the longitudinal direction of the rung, ie perpendicular to the plane of the drawing in Fig. 5. As a result, as will be shown later in connection with the design of the sealing elements, a large part of the individual components required for the mullion-rung construction can be delivered to the construction site in a preassembled state.

Fig. 6 shows a vertical section through the entire post-rung construction 10 of the present invention. To keep Fig. 6 clear, rung connectors 16 , which are located in the grooves 14 b of the rung 14 and would be visible in the present view of the section through a rung 14 , were not shown.

In FIG. 6, facade panels 34, fixed, for example glass plates on the rung fourteenth For this purpose, a spacer bar 28 already indicated in FIGS . 4 and 5 is first pushed over the central groove 14 c of the rung so that two legs 36 of the spacer bar 28 made of plastic on the webs between the grooves 14 b and 14 c on the Grooves 14 b close sides. The spacer strip 28 has grooves 38 which extend in the longitudinal direction and, in the installed position, open upwards and downwards and are used for the clamping or form-fitting insertion of sealing elements in the form of elongated sealing strips. The sealing elements 40 are inserted on the one hand in the grooves 14 a of the profile 14 and on the other hand engage in the grooves 38 of the spacer strip 28 . In this way, on the one hand, a sealing connection is produced along the side of the rung 14 directed towards the outside of the building, and on the other hand, the spacer strip 28 which is merely plugged onto the rung 14 is fixed in position. Finally, the groove 14 b 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 14 , ie in the area of the rung connector 16 , are sealed by the sealing element 40 and no additional sealing measure is required for the fastening elements for the rung connector, not shown in FIG. 6.

The sealing element 40 is formed on the side facing the facade plate 34 as a labyrinth seal and additionally has longitudinal slots 42 which allow the seal 40 to be easily cut along the line 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 14 and post 12 , as will be explained in more detail later. The facade shown in Fig. 6 is closed to the outside by a preferably multi-part cover strip 44 which extends in the longitudinal direction of the rung 14 . The multi-part cover strip 44 shown in FIG. 6 consists of a first profile strip 46 which on the one hand serves to receive strip-shaped sealing elements 48 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 28 and is fastened in the central groove 14 c. 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 52 , which together with the first profile strip 46 forms the cover strip 44, is fastened in a suitable manner on the first profile strip.

The attachment of the façade panels 34 is done on one hand by the clamping contact between the sealing elements 40 and 48, on the other hand, by resting on a supporting member 54 comprising a support to providing on each rung 14 of the of the respective rung extending upwardly facing panels 34th The load that occurs is transferred to the support element 54 via the spacer strip 28 arranged therebetween and, in some areas, the sealing element 40 arranged therebetween to a plurality of fastening elements 56 arranged along the rung 14 , which pass through suitable holes through the spacer strip and in the central groove 14 c Rung 14 to be fixed.

The rung 14 shown in FIG. 6 can already be largely preassembled by the sealing elements 40 already being arranged in the grooves 14 a and engaging in the grooves 38 of the spacer strip 28 which is likewise attached to the rung 14 . In this way, a fixation of the spacer strip 28 is already achieved. Furthermore, the fastening elements can be inserted into the central grooves 14 c 56 is also already at predetermined intervals.

Fig. 7 shows a horizontal section through the post-rung construction. All components which are correspondingly shaped to those in Fig. 6 illustrated are provided with the same reference numerals, even if the components illustrated in Fig. 6 and Fig. 7 are not identical, as it is in Figs. 6 and 7 to cross-sectional views acts, which are carried out once in the vertical direction and once in the horizontal direction.

In the same way as was explained above in connection with FIG. 6, a spacer strip 28 and a cover strip 44 consisting of a first profile strip 46 and a second profile strip 52 are pushed or fastened onto the post 12 shown in FIG. 7. The sealing elements 48 shown in FIG. 7 are also identical in construction to the sealing strips 48 shown in FIG. 6 and running in the horizontal direction. The facade panels 34 are fixed in position on the post 12 extending in the vertical direction only by the clamping installation between the sealing elements. The sealing elements inserted into the first grooves 12 a of the post 12 and again inserted into a groove 38 of the spacer strip 28 differ from those shown in FIG. 6. The sealing elements 58 running along the vertical posts are designed with a view to the targeted removal of the steam or liquid which penetrates from the outside of the building or condenses in the facade area.

Comparing the design of the sealing elements 40 and 58 in FIGS. 6 and 7, it is clear that the sealing elements 40 and 58 have a different shape. While the sealing elements 58 running along the post 12 have a pronounced drainage channel 60 , the corresponding drainage channel 62 of the seal 40 along the rung 14 is only very weakly pronounced. This means that the drainage trough 60 extend along the post deep into the second grooves 12 b, while the sealing elements 40 along the sprouts have only a pronounced very slightly drainage gutter 62nd

In the joint area between rung 14 and post 12 , both the sealing elements 40 along the rung and the sealing elements 58 along the post are divided along the longitudinal slot 42 (see FIG. 6), 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 34 and the exterior of the building, overlapping the lower halves of the seals 58 along the post. This design of the seals creates a liquid- and vapor-tight connection between the rung and the post. The water collected in the essentially horizontal drainage channel 62 of the sealing element 40 is fed in the joint area between the rung and the post into the, as described above, much more bulged, vertically extending drainage channels 60 of the sealing element 58 and is conveyed downward. This creates a liquid- and vapor-tight barrier, which is additionally supported by the fastening of the sealing elements 40 or 58 to the spacer strips 28 .

Another advantage of the design of the sealing elements shown is that the fastening elements between rung 14 and post 12 (see FIG. 4) are arranged behind the liquid- and vapor-tight barrier and therefore no separate sealing measures are necessary in the post-rung connecting area. The same applies to the rung connector 16 shown in Fig. 1 and its attachment in the second grooves 14 b of the rungs. These fastening elements are also located behind the drainage channel 62 and are therefore not to be sealed separately.

Another advantage of the illustrated design of the sealing elements 40 and 58 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 44 and the posts as well as rungs can be significantly reduced. The fasteners 56 for supporting the facade panels do not allow an opening to be created in the hollow profile 14 of the rung, since the fasteners 56 are preferably screwed into the middle, third groove 14 c, a self-tapping fastening element being used which does not form the bottom of the middle, third groove 14 c reached.

The assembly of the post-rung construction works in the following way. The posts are already preassembled in such a way that the sealing elements 58 are each inserted into the first grooves 12 a, the spacer strip 28 is inserted over the webs delimiting the central groove 12 c, and the sealing elements 58 are fastened in the grooves 38 of the spacer strip 28 . The rungs are preassembled in the same way, the only difference is that near the front ends of the rung, on which a rung-post connection is to be made, the seals are not yet connected to the spacer strip 28 and, on the other hand, the seals are in each case protrude the front end of the rungs. The rung connectors are already preassembled on the rungs, but the rung connectors are still slidable.

The rungs can be inserted directly between the posts already arranged at a predetermined distance from the front and then the sliding bolts 22 can be inserted into the correspondingly shaped bore 26 on the side walls of the hollow post profile by moving the rung connector. The rung connectors are then fixed with the aid of the fastening elements 20 , so that the rung connectors can no longer slide back. In the overlap area of the sealing elements 40 and 58 , they are divided along the longitudinal slots 42 in the manner described above and finally placed on top of one another in an overlapping manner. After a possible adhesive fixation of the sealing elements, the facade panels 34 are arranged, the supporting elements 54 and fastening elements 56 required for this are attached, and finally the cover strips with the sealing elements 48 used are screwed to the hollow profiles of the rungs 14 and posts 12 .

The advantage of the present invention is that a very simple connection between posts and rungs has been created, which does not require notching or milling in the post as well as in the rung. There is a straight butt joint between the rungs and the posts, ie both the side wall of the post hollow profile 12 and the end face of the rung 14 each lie against one another and in a common plane.
