Description

The invention relates to a wall holder for fixing a curtain wall to a building wall, wherein the wall holder consists of a voltage applied to the building wall support bracket and a thermally insulated with respect to him substructure adapter.

From the DE 20 2004 008 376 U1 a facade holder is known which serves the thermal decoupling of facade substructures. The façade holder consists of a wall-side fastening element, an intermediate element and a load-bearing, facade-side fastening element. The intermediate element is a plate provided with two rail-like grips. With the Umgriffen it sits positively on the wall-side fastener. Its far wall end is connected to the facade side fastener. The intermediate element has a heat-insulating coating, via which it contacts the wall-side fastening element.

The present invention is based on the problem to develop a wall bracket for fixing a curtain wall on a building wall, which reduces heat transfer between the building wall and the facade without reducing the load capacity with ease of use and great variability.

This problem is solved with the features of claim 1. For this purpose, the support bracket and the substructure adapter are rigidly connected to each other regardless of the arranged between the two parts insulating. At the support angle an insulating body is arranged on the building wall facing the adapter surface.

When using a curtain wall, a substructure made of steel or aluminum profiles is attached to the usually unplastered building wall, such as a concrete wall, to mount and fix the facade panels. In the located between the building wall and the facade panels cavity is usually a z. B. stone or glass wool existing thermal insulation. The latter is preferably anchored to the building wall. Between the thermal insulation and the façade panels there is left behind a ventilated gap whose gap width usually measures several centimeters.

The wall bracket according to the invention consists u. a. from the wall bracket attached to the building wall and the substructure adapter. The wall holder, which is in the ready-mounted facade in the field of thermal insulation, so apart from its mounting joints, z. B. surrounded by mineral wool is thermally largely separated by a first insulator of the building wall and a second of the substructure adapter. Thus, in hot weather, the warmer facade only very little heat through the wall bracket in the building wall initiate. In very cold weather, where the frost limit is usually within the thermal insulation, prevents the first applied to the building wall insulator the removal of heat in the colder zones of thermal insulation.

The 1 shows one on a building wall ( 2 ) wall mount ( 1 ). The wall holder ( 1 ) exists here z. B. from a support bracket ( 10 ), a substructure adapter ( 110 ), two insulators ( 90 . 130 ), two screw connections ( 51 ), a fixing screw ( 41 ) and a washer ( 45 ). On the substructure adapter ( 110 ) is a - shown in dashed lines - thin-walled T-beam ( 5 ) and riveted. The T-beam ( 5 ) runs in 1 z. B. vertically and parallel to the building wall ( 2 ). At him horizontal profiles not shown here are attached, which carry the curtain wall panels.

The support angle ( 10 ) has two legs ( 11 . 31 ), which are oriented substantially perpendicular to each other, cf. three , One leg is the wall leg ( 11 ), with its outer surface ( 13 ) in the direction of the building wall ( 2 ) is aligned. The other leg is the Kragschenkel ( 31 ). He has a flat outer side surface ( 33 ), with the outer surface ( 13 ) includes a 90 ° angle. This outer side surface ( 33 ) closes over an edge directly on the outer surface ( 13 ) at.

After the 1 to 10 has the wall leg ( 11 ) in the illustrated press profile whose material z. B. is an AlMgSi alloy, an inner surface ( 14 ), which are opposite the outer surface ( 13 ) to z. B. 1.5 degrees is inclined, so that its wall thickness in the direction of the Kragschenkels ( 31 ) to z. B. increases one millimeter. The same applies to the part ( 35 ) of the inner side surface ( 34 ), the wall leg ( 11 ) is facing. In this area, the inclined surface ( 35 ) with the outer side surface ( 33 ) also an angle of z. B. 1.5 degrees. This increases the wall thickness z. B. by 4 mm in the direction of the wall leg ( 11 ).

In the front area of the Kragschenkels ( 31 ) are z. B. two holes ( 37 ) for fixing the substructure adapter ( 110 ) arranged.

Instead of drilling ( 37 ), the Kragschenkel ( 31 ) to 4 in the front area z. B. three rivets ( 72 - 74 ) on. The rivets ( 72 - 74 ) by means of a cutting and forming process from the Kragschenkel ( 31 ) bent out. The finished rivet flap ( 72 - 74 ) consists of a spacer rivet bar ( 75 ) and a rivet ( 81 ). The rivet bar ( 75 ) has in the embodiment a width of 12 mm, a depth of 3 mm and a height of 5 mm. The riveting stock ( 81 ) is above the rivet bar ( 75 ) z. B. 5 mm above. It serves the future riveting connection ( 71 ) as the rivet part, the length of which results from the clamping length and the riveting or forming allowance. Between the rivet shaft ( 81 ) and the rivet bar ( 75 ) are the two support surfaces ( 76 . 77 ), on which after connecting the support bracket ( 10 ) and substructure adapter ( 110 ) the latter on the rivet bar ( 75 ) rests.

The rivets ( 75 ) are at least almost perpendicular to the Kragschenkel ( 31 ). They protrude from the Kragschenkel ( 31 ) in the direction in which the wall leg ( 11 ) from Kragschenkel ( 31 ) protrudes.

To 4 have the rivets ( 75 ) of the rivet tabs ( 72 - 74 ) at the support angle ( 10 ) a special arrangement for ensuring a high resistance to deformation transverse to the longitudinal direction of the wall holder ( 1 ) around a surface normal ( 49 ), see. 18 centered on the large side surface ( 133 ) of the clamped insulating body ( 130 ) stands. The central rivet tab ( 74 ) is parallel to the wall leg ( 11 ) of the support angle ( 10 ), while the other two rivets ( 72 . 73 ) aligned parallel to each other at an angle of 90 degrees to the wall leg ( 11 ) are positioned. The rivet flap ( 72 ), see. 2 , primarily absorbs tensile forces coming from the building wall ( 2 ) pointing away. The lower rivet tab ( 73 ) takes over mainly in the direction of the building wall ( 2 ) acting compressive forces, while the middle ( 74 ) is mainly loaded in the load direction.

Instead of the riveted connection ( 71 ) is also a welded connection conceivable. For this purpose, for example, by the support plate ( 110 ) projecting end of the rivet shaft ( 82 ) directly with the support plate ( 110 ) welded. It is also possible to perform a spot welding by the Nietsteg ( 75 ) z. Without rivet shank ( 82 ) on the support plate ( 110 ) is present. In this case, the flat end face of the rivet bar ( 75 ) butt with the support plate ( 110 ) welded.

The substructure adapter ( 110 ) to 1 is a substantially flat and z. B. rectangular support plate, which is a manufactured from an Al-Mg alloy edge plate. This support plate ( 110 ) has z. B. a wall thickness of 3 mm. She has in the support bracket ( 10 ) facing area z. B. four pairs of holes ( 111 ). Their diameters are z. B. 6.2 mm. Two opposing holes ( 111 ) form a fixing pair.

The support angle ( 10 ) facing away, free end of the support plate ( 110 ) has on its outer sides each about 60 mm long clamping spring ( 113 ) on. The clamping springs ( 113 ), here z. B. 5 mm wide serve the provisional fixation of the T-beams ( 5 ) or similar profiles. For larger support plates ( 110 ), the clamping springs ( 113 ) can also be arranged offset inwards, so that on both sides of the individual clamping springs ( 113 ) the support plate ( 110 ).

Between the clamping springs ( 113 ) are in the far wall end region z. B. four recesses ( 114 . 115 ) arranged. The two outer recesses ( 114 ) are circular holes. Their diameter is z. B. 5 mm. The two inner recesses ( 115 ) are long holes that are 5 mm wide and 15 mm long.

For mounting the T-beam ( 5 ) on the support plate ( 110 ) the bridge ( 6 ) of the T-beam ( 5 ) between the clamping springs ( 113 ) and the support plate ( 110 ) clamped, cf. 1 , After aligning the T-beam ( 5 ) on several support plates, the web ( 6 ) through the corresponding bore of the support plate ( 110 ) drilled through. The footbridge ( 6 ) and the support plate ( 110 ) are then by means of a screw or z. B. by means of a blind rivet ( 7 ), permanently connected.

Between the support bracket ( 10 ) and the support plate ( 110 ) is the insulating body ( 130 ) arranged. He is a level, z. B. rectangular plate. He has in the field of screw and / or riveted joints ( 51 . 71 ) corresponding recesses ( 135 ) or drilling. As insulator material, for example, a closed-cell foamed rigid PVC is used. This rot-proof material has a density of z. B. 0.73 g / cm ³ and a thermal conductivity of z. B. 0.09 W / mK. He belongs to the fire class B1. Possibly. can this or another suitable plastic for reinforcing glass and / or carbon fibers z. B. be added in the form of short fibers. As other admixtures mica, graphite, carbon black or other comparable surcharges are conceivable.

The other insulating body ( 90 ) is between the support angle ( 10 ) and the building wall ( 2 ) arranged. He has in the embodiment of a slot ( 92 ) for carrying out the fastening screw ( 41 ). The slot ( 92 ) is usually slightly larger than the slot ( 15 ) of the wall leg ( 11 ), see. 2 ,

Both insulators ( 90 ) and ( 130 ) are z. B. made of the same material and here may have the same cuboid shape.

In the embodiments of the 1 to 4 is the insulating body ( 90 ) on the outer adapter surface ( 13 ) of the wall leg ( 11 ) glued. There are three possibilities for this. In the first case, in the pre-assembly before the adhesive pressing z. B. a flowable adhesive on the adapter surface ( 13 ) and / or the insulating body ( 90 ) applied. In the second case is z. B. on the prefabricated insulating body ( 90 ) a tough adhesive coating, which is covered by a peelable protective film to the bond. In a third case, for bonding between the adapter surface ( 13 ) and the insulating body ( 90 ) at least partially inserted a double-sided tape.

Alternative solutions are in the 5 to 10 shown. The 5 and 6 show a variant in which the insulating body ( 90 ) two z. B. circular holes ( 93 ) having. The wall leg ( 11 ) has two cylindrical pins ( 21 ), the z. B. were prepared by a pressing or deep drawing process. On the cones ( 21 ) is the insulating body ( 90 ) by means of its bores ( 93 ) z. B. frictionally attached, see. 6 , The cones ( 21 ) or the projections each have the function of a wall stop. After tightening the fixing screw ( 41 ), see. 1 , the wall leg ( 11 ) - for example, after compressing the respective insulating body ( 90 ) by 0.01 to 0.3 mm - also with the end faces of the pins ( 21 ) on the building wall ( 2 ) at. This keeps the wall bracket ( 1 ) Also in the case that in case of fire, the insulating body ( 90 ) and / or melt away, still its original carrying capacity. Also, its original mounting position does not change.

In the 7 and 8th is an insulating body ( 90 ) shown for fixing in holes ( 16 ) at the support angle ( 10 ) z. B. two double snap hooks ( 95 ) having. The latter consist of two adjacent snap hooks ( 96 ). The locking hooks ( 96 ) assign each other their back. There is a free space notch ( 97 ), which the latch hooks ( 96 ) during the assembly process before the engagement of the inner surface ( 14 ) to a large extent. After inserting the respective double-pawl hook ( 95 ) through the corresponding hole ( 16 ), the latching hooks ( 96 ) for grasping behind. The hook-shaped projections of the latching hooks ( 96 ) lie on the inner surface ( 14 ) at.

In the insulating body ( 90 ) are after 7 at the height of the double catch pin ( 95 ) z. B. two holes ( 93 ), in each of which a metal or ceramic disk ( 101 ) is inserted or inserted as a wall stop or spacer. Possibly. has the metal disc ( 101 ) a circumferential bridge ( 102 ) to be lost in the respective hole ( 93 ) to be held.

After the 9 and 10 be the insulating body ( 90 ) and the wall leg ( 11 ) with the aid of a step tap ( 23 ) connected. Of the Step tap ( 23 ) has three sections. The first section is the holding section ( 24 ). It is followed by the support section ( 25 ), in turn, the clamping section ( 26 ) wearing. The holding section ( 24 ), which has a larger diameter than the support section (FIG. 25 ) lies at the step of the stepped bore ( 94 ) of the insulating body ( 90 ) to hold the latter. The supporting section ( 25 ), which has a larger diameter than the clamping portion ( 26 ), with a collar on the outer surface ( 13 ) of the wall leg ( 11 ). The clamping section ( 26 ) has a knurl with z. B. paraxial grooves or a serration. By means of the knurling it adheres firmly in the bore ( 16 ).

Of course, one or the other of the types of attachment described herein can be used to also the insulator ( 130 ) before assembling the wall bracket ( 1 ) at the support angle ( 10 ) or on the support plate ( 110 ) to fix.

Both insulators ( 90 . 130 ) may have larger, closed recesses area. These recesses can be covered for thermal insulation with ambient air or another material. This can z. B. have a lower thermal conductivity, which is smaller than that of the Isolierkörpergrundwerkstoffs.

The 11 to 14 show screw connections, with which the support plate ( 110 ) with the supporting bracket ( 10 ) with the interposition of the insulating body ( 130 ) is attached. After the 11 and 12 is per screw connection ( 51 ) in the support angle ( 10 ) first a screw ( 52 ), z. B. M6 × 20, in the bore ( 37 ) used. Should the support bracket ( 10 ) are made of an aluminum alloy, the bore ( 37 ) - to minimize the screw clearance - for example, so narrow that the screw ( 52 ) is just still pluggable. Depending on screw geometry quality measures for a M6 screw ( 52 ) the bore diameter 5.9 to 6 mm.

The screw ( 52 ) is in the support angle ( 10 ) by means of the first nut ( 53 ) attached. The after the 11 and 12 inserted insulating body ( 130 ) has per screw connection ( 51 ) a recess or bore ( 135 ), which is at least as large as the mother ( 53 ) into the hole ( 135 ) of the insulating body ( 130 ) - if necessary with game - fits. The strength of the mother ( 53 ), the wall thickness of the insulating body ( 130 ) correspond.

On the from the insulating body ( 130 ) or the mother ( 53 ) outstanding end of the screw is the support plate ( 110 ) with its bore ( 111 ) postponed. The bore ( 111 ) here has an inner diameter that is 0.1 to 0.3 mm larger than the outer thread diameter of the screw ( 52 ). After placing the support plate ( 110 ) is on the end of the screw, the second, possibly also self-locking nut ( 54 ) and tightened, cf. also 13 , Under the mother ( 54 ) may be a washer.

As in the 1 and 2 shown, the support plate ( 110 ) on the inner side surface ( 34 ) of the Kragschenkels ( 31 ) attached. This moves the neutral fiber ( 119 ) considered as a bending beam support plate ( 110 ) closer to the midline ( 42 ) of the fixing screw ( 41 ).

In 13 is the first mother ( 53 ) from the 11 and 12 through a spacer sleeve ( 55 ) replaced. The spacer sleeve ( 55 ) has, for example, a length that is as large as the height of the first nut ( 53 ). The diameter of the spacer sleeve ( 55 ) corresponds to z. B. the wrench size of the first mother ( 53 ).

To 14 is in the screw ( 51 ) a combination of one with two frets ( 63 . 64 ) stud bolts ( 64 ) and two nuts ( 54 ) used. The centerpiece ( 62 ) of the stud bolt ( 61 ) has a diameter, the z. B. the key width of the nuts ( 54 ) corresponds. The Bund ( 63 ) is firmly at the support angle ( 10 ), while the Confederation ( 64 ) on the support plate ( 110 ) abuts. The nuts ( 54 ) each press the support angle ( 10 ) and the support plate ( 110 ) over the frets ( 63 . 64 ) against the spacer ( 62 ).

In the 15 and 16 is a double-sided riveted joint ( 87 ). The double rivet ( 88 ) is here in the undeformed state essentially a flat plate, which in the central region for the formation of support surfaces ( 76 . 77 ) is a little wider. A comparable single rivet ( 72 ) is in the 2 and 4 shown. The double rivet ( 88 ) differs from the individual rivet shown ( 72 ) only by having on both sides of the spacer rivet ( 75 ) a rivet ( 81 . 82 ) Has. Even after the 15 and 16 the riveting is done by deforming the over the respective component ( 10 . 110 ) protruding rivet shaft. For example only, the rivet shank is deformed here by a splitting process. Of course, the shaft can also be converted to a conventional closing head. Here he can z. B. be a semi-ellipsoid. It is - with corresponding countersinks on the components ( 10 . 110 ) - also possible, the closing head ( 83 ) to sink like a Senkniet. The countersinks can be formed, for example, during the punching process.

17 shows the connection point between the support bracket ( 10 ) and the support plate ( 110 ). To the by the insulating body ( 130 ) conditional deformation visually recognizable, it is shown here exaggerated.

In case of fire, the load capacity of the wall bracket ( 1 ) as long as possible safely. Therefore, in this embodiment, the support angle ( 10 ) and the support plate ( 110 ) z. B. on the off 14 known studs ( 61 ) and its two nuts ( 54 ) rigidly connected. The nuts ( 54 ) are tightened so tightly that the support angle ( 10 ) and the support plate ( 110 ) with the for the screw connection ( 51 ) required residual clamping force against the frets ( 63 . 64 ) of the stud bolt ( 61 ) are pressed. The support angle ( 10 ) and the support plate ( 110 ) are thus fixed on one of the frets ( 63 . 64 ) on. You have to go there 17 - without play - the support distance ( 65 ).

In the regular operating condition with inserted insulating body ( 130 ) to have enough support, he ( 130 ) in undeformed state a wall thickness ( 139 ), which is greater than the support distance ( 65 ). In 1 is, for example, a transverse load ( 9 ), which the insulating body ( 130 ) in the rear area, near the rear end face ( 131 ) loaded on pressure. Now there would be the support plate ( 110 ) without preload on the insulating body ( 130 ), this would possibly be there above average compression, resulting inter alia to a yielding of the substructure in the transverse direction and to a loosening of the screw or rivet connection ( 51 . 71 . 87 ).

Now, if the wall thickness of the insulating z. B. by 1 to 5 percent greater than the support distance ( 65 ), dents when screwing the screw ( 51 ) the support angle ( 10 ) and the support plate ( 110 ) slightly in the area of the maternal circulation. There is then the insulating body ( 130 ) compressed more than in the remaining investment area between the support angle ( 10 ) and the support plate ( 110 ). The same applies to every other connection.

The 18 shows a support angle ( 10 ) and a rear portion of a support plate ( 110 ). Both parts are z. B. made of a stainless steel sheet. The wall leg ( 11 ) of the support angle ( 10 ) has to support on the building wall and storage of - here dashed lines - insulating body ( 90 ) z. B. four support webs ( 22 ), which are each formed by a 90 ° sheet bending. They surround the top and bottom of the insulating body ( 130 ).

Also the front area of the Kragschenkels ( 31 ) has such shaped support webs ( 38 ), the attachment to the support plate ( 110 ) and on the insulating body ( 130 ) serve. The insulating body ( 130 ) contacted with its front face ( 132 ) the upper ( 38 ) and the lower support bar. The lower support bar is in 18 through the support plate resting thereon ( 110 ) obscured.

The support plate ( 110 ) itself also has two of these support webs ( 117 ). The latter are at the rear end face ( 131 ) of the insulating body ( 130 ) and on the inner side surface ( 34 ) of the Kragschenkels ( 31 ) at.
