Description

The invention relates to a support structure for a facade wall and / or associated facade roof, consisting preferably of posts running from top to bottom and preferably horizontal bars inserted between them, posts and bars forming fields for the insertion and holding of wall fillings or glazing, and wherein the post parts and transoms surrounding each field are provided with a frame-like, circumferential seal to which the wall filling or glazing can be held or can be fastened, the circumferential seal by means of a holding foot in sealing grooves located on the room side of areas of the mullions and transoms located on the room side engages, the weather-side post areas and the weather-side locking areas have circumferential chambers on their weather-side end faces, the front of which are spaced from two front strips located from each other are limited (preamble of claim 1). As indicated, the term "facade wall" also means a corresponding facade roof. From the above it also follows that the "facade wall" can run both vertically and at an angle to the vertical. A support structure, as outlined in the preamble of claim 1 above, is known from DE-PS 35 39 002, but only a vertical course of the posts and only a horizontal course of the transoms are disclosed. The frame-like circumferential seal is held mechanically firmly on the room side in a seal retaining groove. However, this seal is disadvantageously designed on the weather side so that a gap remains free due to the weather-related moisture, in particular rainwater. On the weather side, however, there should be a perfect seal against the harmful effects of the weather. The seal is held there only with a further seal retaining groove approximately in the middle of the side wall of the narrow weather-side area of the transoms and posts. However, this has the consequence that the part of the seal which extends from this seal retaining groove to the end face of the narrow areas has no hold at all on the respective profile area, ie depends more or less loosely there depending on the degree of its inherent rigidity. Apart from the fact that this can look unattractive, moisture can also enter in this area with the result of corresponding damage, in particular in cold weather caused by frost damage. The arrangement and function of the connecting elements between the transom and the mullion are disadvantageous in their construction and, above all, in their operation compared to the connecting elements of the invention.

In the older, but post-published EP-A 0 399 778, a supporting frame with a seal is described, in which the retention of end strips of this seal differs in structure and function from the object of the present invention. The seal described there cannot circulate like a frame.

The object of the invention, in contrast, is to improve the structure and function of a supporting frame according to the preamble of claim 1, and in particular to the effect that the circumferential seal as a whole, and in particular weather-side, keeps moisture perfectly away from the parts to be protected and in particular their penetration prevented in the interior of the building.

To solve this problem, starting from the preamble of claim 1, it is initially provided that the chambers serve the clamping bracket of the seal by the seals on both sides of the weatherproof post and transom areas with webs running out in end strips in end strips which are arranged and dimensioned in this way that they fit the plug-in or plug-in the front strips of the weather-side mullion and transom areas in the space of the respective chamber between these two front strips under a clamp fit, the end strips resting with sealing action on both the end faces of the front strips of the weather-side mullion and transom areas as also rest against the end strips on these with the abovementioned clamp fit, and that the end strips rest against one another over their entire length with a sealing effect (characterizing part of claim 1). The entire narrow, weather-side area of the mullions and transoms, including the end face of this area, is thus completely covered by the seal, wherein entry of moisture into the area of this end face or a chamber adjoining it is avoided. The jamming provided there according to the invention is particularly advantageous on the weather side because of its impeccable sealing and is much better than simply holding it by reaching behind an undercut. In particular, a perfect self-holding jam of the end strips of the seal in this space of the chamber between the two end strips reached. At the same time, the front strips are covered on the weather side.

Claim 2 includes the arrangement of a support structure according to the invention on a facade wall and / or on an associated facade roof.

The invention further provides according to claim 3 that any other components of the support structure, provided that they are in the area of the circumferential seal, are matched to the design of this seal.

An embodiment of the invention further provides, according to claim 4, the possibility of a filler at the ends of the narrow weather-side locking areas, against which the end strips also bear with a sealing effect.

1 to 3 show the basic structure of a support structure according to the invention, the seals in FIG. 2 being recognizable and in particular FIGS. 10, 10a to 10c in particular. The posts 1 consist of a narrow, weather-side post area 1a and a wider, room-side post area 1b, which is primarily used to generate the greatest possible flexural rigidity and also to connect superimposed posts or post parts (see in detail in Fig. 3 and its explanation). The post area 1a serves to receive the seal.

While the posts 1 are either vertical or at an angle to the vertical, the transoms 2 run horizontally. They also consist of a narrow, weather-side locking area 2a and a wider locking area 2b in the drawings on the rear side of the room. The mullions and transoms each form fields in which wall panels or glass panes can be inserted (see also the later explanations). The front surfaces of the fields form a level with the adjacent transoms and posts. Such a facade wall is usually a load-bearing structure. In certain applications, however, it could be applied to existing structural parts.

As a rule, the transoms 2 are slidably connected to the posts and there is also a sliding connection between posts or post parts lying one above the other (see FIG. 3) in order to be able to compensate for the different lengths of these components at different temperatures. The cross-sections through the posts and transoms are the same; except for the approximately square section of the post area 1b on the room side, which is located on the post and is at the rear in FIGS. 1 to 3. This results from the fact that the circumferential, frame-like seal to be explained below is always intended to surround an entire field and thus abuts both bars and two posts and is held on their cross sections. Because the post 1 and the transom 2 are the same at least in the narrow, weather-side area 1a, 2a and in the sections in which the sealing grooves 4 and grooves or hollow chambers 3 to be explained are located, in principle one and the same profile can be used can be used for the manufacture of the posts, as well as for the manufacture of the transoms, with only the recesses for inserting the plug-in bolts still having to be provided in the post. Depending on its use, the same cross-sectional sections of the profile can either be the hollow chambers 3 of the bolts for receiving the connecting elements or the grooves 3 of the posts, into which the plug pins are inserted and locked in a resilient manner in the holding position. The seal retaining grooves 4, which are provided on the weather side on the hollow chambers of the transoms, are thus also present when the profile is used as a post due to the same cross-sectional shape mentioned above. In this way, the storage of profiles for the creation of such a supporting structure and the tool costs can be reduced by about half. This has an effect in particular if several profiles with different moments of inertia or resistance have to be kept available for differently loaded supporting skeletons.

The circumferential seal 7 is designed and arranged that it is both airtight and watertight and that movements of the transoms and posts by temperature changes and the effects of external loads (eg wind) do not impair their sealing effect. Also a distance-variable joint of two superposed and aligned post parts is covered airtight and watertight by the seal 7. According to FIGS. 10, 10a and 10c, the seal 7 consists in cross section of a web 7 'which bears on the smooth, uninterrupted side walls of the narrow, weather-side locking areas 2a shown here and on the one hand ends in a foot 8, which has locking lugs 8' behind Projections 4 'of a retaining sealing groove 4 engages. At the other end 7 ″ of the web 7, which is at the bottom in FIG. 10 and can also be seen in FIG. 10c, there are end strips 30 which are connected to the web ends 7 ″ via short bends 30 ′. The same arrangement is given for the weather-side post areas 1a. The parts 7 ″, 30 ′ and 30 each encompass end strips 6 and thus the end faces of the weather-side region 1 a or 2 a of the posts 1 or latch 2 and are held with a clamp fit in a chamber 5, the slot opening 5 ′ of which lies between the end strips 6 and opens into the end faces of the aforementioned weather-side regions 1a and 2a. To increase the aforementioned clamping effect, the end strips 6 are formed on their inner walls 32 obliquely inward. The outer sides of the end strips 30 of the seal are correspondingly oblique (see item 34), ie the outer wall of the one end strip and that of the other end strip together form a cone tapering towards the interior of the chamber 5. This arrangement and the dimensions of the aforementioned parts are such that after insertion of the end strips 30 between the opposing end strips 6 and application of pressure from the outside, here by the pressure strips 22, 22a, the end strips of the seal 7, which is made of an elastic material, are joined together and brace with the end strips 6, so that the end faces of the weather-side mullion and transom areas 1a, 2a are completely waterproof and windproof is covered. This also applies to a filler 9 to be explained in more detail below.

10 also shows the holding of an insulating glazing 68, which is held and sealed with a glazing bar 45. Furthermore, a UV radiation and weather-insensitive edge bond 67 can be provided between the panes of the glazing. For a better overview, the seal 7 with glazing bead etc. is only shown in the left half in FIG. 10, while the right half shows the components of the post, the transom, the pressure bar without the seal 7, the glazing bead 45 etc. Completely assembled, however, the seal 7, glass strip 45, etc. are also provided in the right half, as shown in FIG. 2, for example, or in FIG. 11 for the variant of the invention to be explained below.

The embodiment of FIGS. 11 and 12 shows a so-called expansion post, consisting of the two halves 64 and 64 ', which are assembled in the direction of arrow 64' ', as will be explained in detail below. In this case too, the circumferential seal carries the glazing 68 on both sides. The seals 7 encircling the fields therefore also serve to support the insulating glazing (or a corresponding panel).

The circumferential seal 7 is provided with a bevel 29 (FIG. 10a) which is directed like a corresponding bevel 28 of the weather-side wall of the room-side mullion or transom area 1b or 2b. The length of the web 7 'is, however, dimensioned such that in the installed state (FIG. 10) the weatherproof post or transom area 1a, 2a with its end strips 6 exerts a tension in the direction of the arrow 31. As a result, different manufacturing tolerances of the profiles and Seals balanced and made sure that the web ends 7 '' always rest on the end faces of the end strips 6.

Fig. 3 shows how several post parts with their room-side areas 1b lying flush one above the other by a connector inserted into both areas 1b, e.g. Steel tube 62, can be connected. This connecting piece is firmly connected to one of the two stacked post areas 1b arranged one above the other, while the other post area 1b can slide with its inner surface against pressure-resistant blind plugs 63 of the steel pipe 62. The blind plugs 63 scrape off when inserted for the first time and thus bring about a play-free sliding connection between the parts 62 and 1b. In the chamber 5 of the weather-side post area 1a, a bolt 18a is provided, which belongs to the post part, the area 1b of which is firmly connected to the connecting piece 62. The other end of the pin 18a is also accommodated in the chamber 5 of the other post part 1a, which is guided with its area 1b sliding on the steel tube, with a sliding fit. A screw connection or pin 65 secures the bolt 18a against sliding downwards.

3 also shows the two seals 7, the glazing bar 45, a pressure bar 22 and a clamping profile 57. The same arrangement is also provided for the bolts 2.

The pressure strips 22, 22a are screwed by screws 69 to the end faces of the weatherproof mullion and transom regions 1a, 2a (see also FIG. 11). The pressure bar 22, 22a engages with a central web 22 'in a groove 37 which is formed by the end bars 30 (FIGS. 10 and 10c). The fastening screws 69 are screwed through the middle of the pressure bar 22, 22a into the channel 37 at locations where air chambers 35 are located in the end bars 30. These air chambers 35 can pass through the end strips over their entire length. The distance measure 36 between the outer sides of these air chambers 35 corresponds approximately to the diameter of the screws 69. This arrangement prevents the formation of a gap between the adjoining end strips 30 when the screws 69 are inserted.

10 also shows the attachment of the clamping profile 57. It engages with a protruding edge 58 (see FIG. 10b) behind a bead 59 of the respective pressure bar 22 and is in this position by striking an inner collar 61 of the clamping profile 57 on webs 60 the pressure bar 22 or 22a fixed. This leaves enough space for glazing wedges or strips 45 (see above). These wedges or strips are at least partially covered by the clamping profile 57. This is optically much cheaper than the previously usual resting of the outer leg of the glazing wedge on the clamping profile.

In order to compensate for the longitudinal expansion or contraction of the mullions and transoms in the event of temperature changes, filler pieces 9 and molded parts 40 are designed and arranged as described below.

For this purpose, a pressure-resistant filler 9 is attached to the end of the respective end of the narrow weather-side region 2a of the respective latch 2, specifically by means of a pin 9a of the filler, which is inserted into the cavity 5a between two insulating webs 70 of the narrow, weather-side latch region 2a with a clamping effect is. A support bolt 18, which penetrates into the chamber 5 of the narrow, weather-side locking area 2a, also penetrates a corresponding bore of the filler piece 9. The filling piece 9 has on its weather-side end face the same cross-sectional configuration as that of the weather-side locking area 2a, so that the end strips there as well 30 of the seal can be inserted and clamped. In the fully assembled position according to FIG. 2, the filler indicated by dashed lines abuts the side wall of the narrow, weather-side post area 1a of the adjacent one Post. Thus, the seal 7 can be guided from the weather-side area 2a of the latch 2 over the filler 9 and then bent through 90 ° over the narrow, weather-side area 1a of the post 1 and in the aforementioned areas and in the filler piece, as explained with reference to FIG. 10, be held firmly. However, the filler piece 9 does not have the warmed or room-side, widened area 2b of the bar 2. This allows the respective bar with the end face of its room-side area 2b to abut the side wall of the box-shaped, room-side area 1b of the post 1 facing it ( see FIG. 2), the distance b of the aforementioned side wall being bridged by the filler 9 from the wall of the associated weather-side post region 1a (see FIG. 2). The filler thus assumes the function of the weather-side cross-sectional area 2a of the bar 2 in the area b.

The above-mentioned support bolts 18 have the task of absorbing vertical loads due to the filling elements, for example glazing. You are initially housed in the chamber 5 of the bolt, each bolt receives a support pin 18. After inserting the respective bar 2 transversely to its longitudinal direction into the position between two posts to be connected by it, the respective support bolt 18 is removed from the chamber 5 into the filler 9 and through the opening 19 of the adjacent weather-side post area 1a into the filler 9 of the bar the other side and finally inserted into its chamber. According to this, the carrying bolts 18 can be limited in their movement in the longitudinal direction of the bolt by fastening screws 21 of the pressure bar 22a which can be brought in front of their ends so that a relative displacement to the respective bolt can only take place to a desired extent corresponding to the possible thermal expansion or shrinkage. In this connection it should be noted that the pin 18 according to FIG. 1 penetrates a bore 19 of the weather-side, narrow area 1a of the adjacent post 1 and the other Side protrudes so far that there is also a filler 9 (not shown) and the left end 18 of this bolt can engage in the cavity 5 of the bolt located there.

Furthermore, the joint of the pressure bar 22a of the bar 2 can be sealed against the vertically running pressure bar 22 of the post 1 by an elastic molded part 40 (FIG. 5), which is further shown on the left in FIG. 2 and on the right half in FIG. 10. The elastic molded part 40 has holding feet 41 which can snap into grooves 42 in the horizontally extending pressure bar 22a. 5 is formed in a zigzag shape (see the solid line 43). It rests with the nose 40 'on the pressure bar 22, the elasticity of the zigzag arrangement 43 making this possible when the pressure bar 22a with molded parts 40 provided on both sides is pushed between the pressure bars 22 which have already been assembled. The zigzag arrangement effects a seal even with tolerances in the cutting of the transom pressure bars 22a and / or assembly tolerances of the posts 1 with their pressure bars 22 or also with thermally induced expansions or shrinkages. In addition to the cross section according to FIG. 5 of the molded part 40, this can also be seen in perspective from FIG. 6. The lip 40 'is otherwise shaped so that the cover strip 57 can be pushed over the pressure strip 22 with a clamping effect (see Fig. 10). The assembly sequence is such that first the pressure bar 22 of the post is screwed on, then the pressure bar 22a of the bolt is screwed together with the molded parts 40 and then finally the cover bar 57 of the pressure bar is clamped on. The upper and lower edges (based on the illustration in FIG. 2) of the elastic molded part are aligned with the corresponding edges of the latch pressure bar 22a and also have end faces 44 which form a pressure area for the outer legs of the glazing bars 45. The pressure strips 22, 22a protrude, preferably with inclined facade walls, only slightly beyond the weather-side surfaces of the filling elements 68, for example glazing or Sheet metal panels, in front. As a result, the drainage of surface water is hampered as little as possible.

A corresponding molded part 40 can be provided between the pressure strips 22 of two post areas 1b located one above the other in FIG. 3. The expansion joint 66 between these two pressure strips is hereby bridged and closed. The weather-side area 1a of the post is also covered by the seal 7, so that air and water tightness is also ensured here.

It should be mentioned that the pressure strips 22, 22a are securely fixed due to the penetration of their web 22 'into the groove 37. However, the channels 37 are interrupted (partitioned) shortly before the cross joint 39 by transverse webs 38, which can be seen both in FIG. 2 and on a larger scale from FIGS. 13a, 13b and 20, 20a. This prevents water reaching the groove 37 from reaching the cross joint 39. The grooves 22 'compress, provided they run vertically, the resilient material of the transverse webs 38 together.

In the area below the glass pane in which the weather-dependent composite part 67 is located, there must be no high air humidity. Water that accumulates there must be drained off. In the case of vertical facade walls, openings 47 in the pressure strips 22 can serve for this purpose, the opening width of which is located in the region of the upper edge 48 of the adjacent seal, so that water collecting on the seal is drained through the openings 47 (see FIG. 2). In the case of inclined walls, a tube 49 (FIG. 8) can be provided for the aforementioned drainage in the rebate base, which tube is guided downward both through an opening 50 in the circumferential seal and through a corresponding opening 51 of the filler piece 9, and thus the moisture derives downwards. The preferred The structure of such a tube from two parts 49a and 49b can be seen in FIGS. 8 and 9, which shows the detail encircled in FIG. 8 on an enlarged scale. The two parts 49a, 49b are joined together in the central region of the tube by means of locking cams 52 which run around in a ring. The outer ends of the tube parts are widened to a larger outer diameter 55 by means of bends 54. If, according to FIG. 9a, the opening 50 of the circumferential seal is created by a predetermined breaking point 50a, which, however, corresponds to the outer contour of the tube end 53 in a smaller diameter, the two tube parts 49a, 49b can be inserted through the opening 50 and Allow it to lock at 52 so that it is flush with the surface 56 of the circumferential seal 7. The dotted circles 50 in FIG. 2 show the weakened circular cross section 50a, from which the part of the seal 7 which is surrounded by it is pressed out in order to create the opening 50.

11 and 12 show an embodiment of the invention, in which the transoms 2 are firmly connected to the post halves on two post halves 64 and 64 'and without any possibility of sliding. This is done by the connecting elements 11 to be explained in more detail below, which are inserted with their bolts 16 into the longitudinal grooves 3 of the posts and are each fixed by means of a resilient tensioning element 17. This fixation can be released by removing the tensioning elements. Furthermore, there is a fixing of the connecting element 11, which will be explained in more detail, in the hollow chamber 3 formed by the longitudinal groove 3 of the bolt, which can also be detached again. In order to have the necessary compensation for changes in length due to temperature fluctuations, the post half located on the right in FIG. 11 and labeled 64 'can be moved to the right and left (see arrow 64'') without the post half 64 left in FIG. 11 moving becomes. Such post halves 64 and 64 ', which are movable relative to one another, allow thermal expansion and shrinkage. The Both post halves 64, 64 'form the wide, room-side post area 1b (see FIG. 1). Due to their one-piece construction, the post halves 64, 64 'form integral frame parts. The narrow, weather-side area 1a (see also FIGS. 11 and 12) is only provided on one of these two post halves, here the right post half 64 ′. The seals 7 protect both post halves 64, 64 'against the entry of air and water. In particular, this also applies to the space or gap 98 which exists between the two post halves and which allows their displacement in the direction of the arrow 64 ″. For this purpose, the seal 7 shown on the left in FIG. 11 is guided from the narrow weather-side region of the one, here right post half 64 'past the gap 98 between the two post halves to the other, here left post half 64. Thus, the cavities or chambers are also sealed, which are located in FIG. 11 in the lower region of the halves 64, 64 'and partially serve to accommodate the sealing feet. The circumferential seal 7 is thus also used at the same time for sealing the two post halves. The arrangement according to FIGS. 11 and 12 creates finished facade elements which are assembled at the construction site. Seals 64 '''are provided.

The above-mentioned connecting elements 11 are first slidably provided in the hollow chambers 3 of the wide, bolt area 2b on the room side, which penetrate the entire bolt in its longitudinal direction and are open on its end faces for the insertion of the connecting elements 11. These hollow chambers 3 are limited on one side by the sealing retaining grooves 4 for receiving the sealing base 8 (see also FIG. 1), so that the hollow chambers 3 with the parts 4 have a double function (receiving the retaining base of the seal and receiving the connecting elements 11) . The basic construction of the connecting elements 11 can be seen in FIG. 1, in particular the individual illustration in FIG. 1 on the right. This arrangement has the main advantage that No special precautions have to be taken for the reception of the connecting elements 11 and that in particular the wider, room-side region 2b of the bolts only has to have a depth t such that this is sufficient to form the hollow chambers 3 with sealing retaining grooves 4, but that there is no other space depth-demanding chambers, holding grooves or the like must be provided. After inserting the connecting element 11 into the hollow chamber 3 of the bolt and fixing its plug pin 16 in the groove 3 of the post by the clamping element 17, the bolt is fixed to the post by screwing in a grub screw or the like 23 into the connecting element 11 in the hollow chamber 3 the bolt fixed in such a way that the protruding from the corresponding threaded bore 27 tip 24 (see Fig. 7) of the grub screw on the friction of its screw circumference 24 'on the wall 13 of the hollow chamber 3 by the screw rotation a transport of the bolt 2 in the direction of Post 1 causes. This leads to a play-free connection or butt joint of the bar 2 on the post 1, this connection being finally fixed by further turning the screw 23 and the penetration of the screw circumference 24 ′ into the material of the wall 13 of the bar 2 (FIG 7). In order to allow contact of the screw circumference 24 ′ on the wall 13 first, the half tip angle 25 of the screw tip 24 is larger than the angle of incidence 26 of the threaded bore 27 in the connecting element 11 on the wall 13 of the hollow chamber 3 in the bolt 2.

The fastening of the transoms 2 to the post 1 can, however, and this is a preferred embodiment of the invention, be carried out to compensate for changes in length of the parts due to temperature fluctuations, the connecting elements 11 with bolts 16 already explained above also being used. Here, too, the connecting elements 11 are displaceably accommodated in the bars 2, specifically in their hollow chambers 3 (see Fig. 1 right half). However, there is no provision for fixing the transoms to the posts. Rather, the bars slide on the connecting elements. In this preferred embodiment of the invention, the posts are in one piece (see, for example, FIG. 1). The distance between two post walls, between which a transom is inserted, must be so large that it also absorbs the maximum expected length change of the transom, which is caused by an increase in temperature. The connecting elements 11 transfer the load of the field filling (eg glazing) from the transoms 2 to the posts 1.

The connecting elements 11 are inserted with their bolts 16 into the recesses 12 of both walls 13, 14 of a groove 3 of the post, namely its wider, area-side post area 1b. The post has on both sides a groove 3 with the two walls 13, 14 and a bottom wall which has a recessed shoulder 15 which extends over the entire length of the groove 3. The socket pins 16 are of such a length that, in the holding position of each socket pin 16, only the pair 13, 14 facing it penetrates through the post walls. With this, each transom can be inserted into the area between two posts from any direction, the end faces of the transom lying against the associated side of the wide post area. Then the connecting elements with plug pins are to be moved so far that the plug pin in question passes through the recesses or bores of the pair of post walls facing it. This work can be carried out by a single operator, first at one end and then at the other end of the bar in question. Then you can be connected to a post that is already connected on one side with a bolt, as explained, on the other side with another bolt, the plug pins of which can be inserted into the recesses or bores of the wall pair of the same post facing it. Since every bar on each side of the post two plug pins can be inserted into corresponding recesses or bores of the associated pair of post walls, this can be used to secure the bolt in question against rotation or pivoting about its longitudinal axis. This also ensures double securing and a doubling of the load capacity. In particular, assembly is facilitated by the bars being able to be brought into the respective connection position from each side, that is to say also from below, to the posts which are laterally delimited.

In the inserted position there is a flat 16 'of the bolt 16 of the connecting element 11, exactly opposite the above paragraph 15 of the groove 3. To releasably fix this position of the bolt 16 and thus the connecting element 11, a resilient clamping element 17 with contact surfaces 17 'is provided, which extends in the longitudinal direction of the respective groove 3 of the post, or to the two bolts 16 (the same connecting element 11 with bolt 16 is in the hollow chamber 3) present on the latch 2 at the bottom in FIG. 1. The clamping element 17, preferably a resilient sheet metal strip, lies in the fixing position with its flats 17 'on the flats 16' of the bolts 16 (see FIG. 4). The clamping element 17 engages with a middle part 17 ″ and its two ends 17 ″ ″ in the shoulder 15 of the respective groove 3. Since the abovementioned flats 16 ′ of the bolts are laterally delimited by walls 16 ″, the two connecting elements 11 are hereby held securely on the post region 1b on the room side. It is understood that, if necessary, only one connecting element 11 can be provided. A bend 17 '''of the above ends can be used to hold a clamping element pushed in from below on one of the bolts.

As already mentioned above, in the embodiment of the invention according to FIGS. 11, 12, in which the bolt fastening explained is provided by means of the grub screw 23, the bolts 16 of the connecting elements 11 are fastened to the posts by means of the tensioning elements 17. However, this connection is not shown separately in FIG. 11 for the sake of simplifying the drawing. The clamping elements 17 can with their above. Hold ends 17 '' '' and the middle section 17 '' in the respective groove 3 of the room-side post area.

The respective bolt 2 is also carried by the weather-side bolt 18. The bolt 2 is slidably guided on this bolt 18 and the connecting elements 11 in its longitudinal direction, whereby the above. Thermal expansion can be compensated. During assembly, the procedure is such that the latch is first inserted transversely to its longitudinal direction with connecting elements 11 already inserted into the end face between the posts in question and then through the opening of the hollow chamber 3 with the bolts 16 into the recesses 12 between the seal retaining grooves 4 Post walls 13, 14 is inserted. It is essential that each bolt 16 passes through only the walls 13, 14 of the adjacent groove 3; but not the walls of the groove on the opposite side of the post. Then the securing takes place by the resilient part 17, which is introduced through the weather-side opening of the groove 3. Finally, the bolt 18 is pushed into the desired position.

It should be mentioned that in the case of such posts which delimit a facade wall on the outside thereof, transoms are only on one side wall of the post in question. In this case, in order to form the front seal of the narrow post region 1a, a seal 95 is also provided on the outer side wall thereof and its end strip 30 is clamped on the end face to the end strip of the other seal (see above) and with its extended web 7 '' is glued to the respective lateral outer wall (Fig. 19).

It has already been mentioned at the beginning that the invention can be used both for vertical and for inclined facade walls. In practice, both of the aforementioned angular positions of the facade walls or corresponding wall parts often occur. Posts can also run in a direction that deviates from the vertical. Likewise, bars can run in a direction that deviates from the horizontal.

In order to implement the transition from a vertical facade wall to a roof facade wall which runs at its top and runs obliquely to the vertical and is designed according to the invention while maintaining the desired sealing effect, a double-walled sealing part 93 is provided according to the exemplary embodiment in FIG. 13, which has two webs 7 '' Each with a weatherstrip end bar 30 and a room and warm connection 71. The two bolts 2 present here can be pivoted about a common axis of rotation 72 in the plane of the drawing, there being a seal through the connection 71. On the weather side, the narrow areas are sealed both by the aforementioned seal 93 and by seals 7 according to the previous exemplary embodiments.

In the example in FIG. 14, the transition from an upper, vertical wall part to a wall part running to the left / down below is shown. Weather protection is provided here by a seal 94, which engages with end strips 30 according to the preceding exemplary embodiments in the end face of the narrow, weather-side locking regions 2a and seals there. This also prevents moisture from penetrating in the direction of arrow 73. This connection is on the room and warm side covered by two cover strips 74, 75 which are rotatably hooked together (76).

The examples of FIGS. 15 to 18 show a central post 1, which is constructed in principle in the same way as the bars described above, two bars 2 being to be arranged in different angular positions both with respect to the post 1 and with respect to one another. This is done by pivoting the latch 2 around the point or axis 77 in pivoting directions which lie in the plane of the drawing. Once the desired swivel position has been reached, it is fixed in place by a screw connection 78 indicated by a dot-dash line. Then a seal 93 is attached, which corresponds in structure to the seal 93 from FIG. 13. In connection with this, it can be seen from FIG. 15 that part 79 surrounds axis of rotation 77 and is connected to weather-side region 1a of the post. The parts 80 of the left hinge part and 81 of the right hinge part, which are designed in the shape of a circular arc and surround the part 79, can be shifted with respect to one another and part 79 can be slid relative to one another when the bolt 78 is pivoted appropriately until after the desired angular position the screw connection 78 has been reached Parts 1a, 79 to 81 is screwed through.

In the present exemplary embodiment, the pivoting of the bars 2 can take place approximately in an angular range α = 20 ° to 90 °. 16, 17 so that the part (joint base profile) 79 is clamped over the end strips 6 of the weather-side narrow profile area 1a. A joint part 82 with the circular-arc-shaped part 80 and a further joint part 83 with the circular-arc-shaped part 81 are placed over the joint base profile 79, as already stated. After the angular position has been determined, the screw connection 78 is carried out. The joint parts 82 and 83 are provided with webs 84, 85, which, in conjunction with elastic sealing profiles 86, form the joints to the cavity 87 of the post 1 close, ie seal to the outside.

Installation and fastening of the latch 2, as well as the design and installation of the circumferential, frame-like seals 93, 94 is carried out in the same way as explained for the other exemplary embodiments. This also applies to the designs according to FIGS. 13 and 14.

As already mentioned above, the seals 93, 94 have essentially the same function and structure as the seal 7, which was previously shown and explained in detail. This applies in particular with regard to the construction and function of the end strips 30. However, the seals 93, 94 are not used to hold or fasten the wall filling or glazing. They also lack the engagement of a support foot according to para. 8 in the sealing grooves of the mullion or transom located on the room side.

The pressure strips 22b are screwed on as usual. They have a bearing surface 88 for fastening 89 of articulated cover strips 74, 75, and a receiving groove 90 for fastening a clamp holder 90 '. The cover strips 57a are pushed into the clamp holder 90 until a cam 91 engages behind a groove edge 92. The fastenings 89 of the joint cover strips 74, 75 are thus covered.

The advantage of these joint cover strips 74, 75 is that they can be set in different angular positions of the angle and that the length X of these cover strips can be adapted to the particular circumstances by simple trimming. These joint cover strips can already be delivered from the warehouse with surface treatment. Extruded profiles such as the mullions and transoms are also preferred, so that there are no color deviations to be feared.

Instead of producing the all-round sealing frame completely made of correspondingly extruded profile parts in accordance with para. 7, 93 and 94, the ends of this strand-shaped profile being glued to one another, if desired, the circumferential seals 7, 93 and 94 can also be produced in such a way that sealing parts (so-called "running yard goods") are produced from the factory or at the construction site ") can be connected to corner pieces 96 (FIGS. 13a, b) or 97 (FIGS. 20, 20a) by vulcanizing or gluing. These corner pieces fill the corners of the fields on mutually abutting transom and post parts and are provided with channels 37 and transverse webs 38 (see, for example, FIG. 10). In the manufacture of the complete sealing frames in the factory, the appropriately tailored strand-shaped seal is vulcanized together by pouring in the liquid mass of the shaped pieces 96 and 97. When the complete sealing frame is manufactured on the construction site, pre-vulcanized form corners and the "running yard goods" of the strand-shaped seal are delivered there, whereby the strand-shaped sealing parts cut to the appropriate lengths are connected to the fittings by gluing.

13a, 13b shows the aforementioned variant of the invention with parts at an angle to one another according to FIG. 13. Surface 99 lies against the post wall.
