Abstract

The mounting to fasten a profile (3,4) at a building wall has a U-shaped holder (1). The holder base plate (5) is mounted to the wall, and the two projecting holder legs lie on both sides of the profile (4), to be locked to it. A torque-free mounting is achieved by the holder legs (6) and flat leg plates (2) which grip the profile on both sides.

Description

The invention relates to a device for attaching a profile to a Building wall, with a U-shaped bracket with one for attachment to the Building wall set up base plate and two angled from the base plate protruding legs that lie flat on two sides of the profile can be brought and connected to the profile there.

Devices of this type are used in particular for fastening facade elements used on building walls. That by means of the U-shaped For example, the holder attached to the wall of the housing is a storey-high Box profile designed on which facade panels can be attached.

It is known to the box profile with the U-shaped holder as a fixed point connect while for training floating points that are different thermal expansion of the substructure and the facade panels can take up by angular agraffes with vertical slots can be realized in which fasteners for a flat leg, for example of a T-profile can be used. The use of the known Angular agrapes, however, lead to the formation of a torque on Attachment point of the agraffes to the building wall.

From EP 0 067 970 B1 an agraffe is known which consists of a V-shaped one There is an aluminum part that is attached to the bottom of the V on the building wall and the two legs of which each have slots into the corresponding one Projections of a flat holding plate using the elasticity the leg can be snapped. In this way, for example Attachment of a T-profile without introducing a torque in the regular attachment point formed in the by a dowel with screw Gehäudewand.

For heavy facade panels or extending over several floors Holding profiles for the facade panels, it is advantageous to hold the profiles train larger loads, for example as a box profile, as hat profiles, as U-profiles etc. The holder known from EP 0 067 970 is for such profiles not useable.

The use of the U-shaped known for the formation of fixed points Holder also has the disadvantage that for different The distances between the facade panels and the building walls are also different U-shaped holders with different leg lengths are needed and consequently must be kept in stock.

The invention is therefore based on the object of a fastening device of the type mentioned at the beginning to create the attachment of a high Profiles that ensure stability, such as box profiles, U profiles, etc., A high degree of stability ensures the cost of warehousing reduced and easy to manufacture.

According to the invention, a fastening device is used to achieve this object of the type mentioned above, characterized in that the legs of the U-shaped holder by integrally connected to the U-shaped holder Thigh lugs and each overlapping on the thigh lugs are formed adjacent to these connected flat leg plates.

The fastening device according to the invention for the attachment of stable Profiles by means of a U-shaped holder is thus constructed in several parts and consists of the U-shaped holder, which is, however, only comparatively short Has leg approaches and is not directly connected to the profile. The connection to the profile is made via the flat leg plates, which lie flatly overlapping on the leg approaches and with these get connected.

The inventive design of the fastening device enables that even for different distances of the facade panels from building walls always the same U-shaped holder can be used and only that easy to store flat leg plates in several, bridging the distance Lengths are kept in stock.

The connection between the leg approaches of the U-shaped holder and the leg plates can be fastened with conventional fasteners, i.e. with screws and / or rivets. There is training as a benchmark, however also possible as a floating point by screwing or riveting through holes protrude through, one of which is designed as a traditional elongated hole.

In a particularly preferred embodiment of the invention, the Connection between a flat leg plate and the associated one Thigh approach using by punching and bending the flat Lanyards manufactured materials. This will make the use separate connection means, such as screws or rivets, are unnecessary. In addition, there is a very simple production, since both the U-shaped Holder as well as the flat leg plates, each with the connecting means can be produced from flat material. In particular this embodiment enables the use of corrosion-protected steel sheet for the fastening device according to the invention, since the design of the holder from extruded profiles is not required.

In a preferred embodiment of the thus produced, in one piece with the parts of the Fastener formed connecting means is a curved approach and an associated vertical slot arranged so that an oblique Insert the approach into the vertical slot and lie flat on top of each other the overlapping parts of the leg approach and leg plate with a Leg movement takes place around a vertical axis in the area of the shoulder and the approach then a stop for translational movement of the Leg plate forms relative to the leg approach in the direction of the leg. This training allows the leg plate to be attached to the associated leg approach, especially if two approaches and two associated vertical slots are arranged one below the other.

When swiveling the leg plate into flat contact with the leg attachment preferably finds a locking of leg approach and Thigh plate to each other instead, and at a distance from the vertical Slots.

The locking is preferably by a cooperating with a recess Elbow formed, the locking by an elastic Locking of the bend can be realized in a recess or preferably the offset has a head piece and a smaller neck piece and a through opening for the formation of the lock for the Headpiece of the bend is provided, the through opening downsized so that the neck piece passes through, the head piece but is no longer feasible. The lead-through opening is thus designed in the manner of a keyhole opening, the locking by the weight of the one sliding down in the lead-through opening flat element takes place.

In all cases, the lock can be designed so that a relative translational movement perpendicular to the plane of the leg is made possible to realize a floating point.

The correct functioning of the locking is supported by the fact that the Reduction of the through opening is realized by means of a slope and that preferably also the transition from the head piece to the neck piece the bend is formed by a slope.

For safe guidance of the connection between the leg attachment and the leg plate, it can be particularly useful when training as a floating point be when angled guide pieces are guided in vertical elongated holes are movable.

For the production, it is expedient if all the bending processes on the flat Connection plates are made and the U-shaped holder only is provided with punched openings.

The parts of the flat leg plates that do not overlap with the leg approaches serve to connect with a profile, which is preferably used as Box profile, is designed as a U-profile or as a hat profile and for example can extend vertically to storey height, so that the profile of several such fasteners is held.

The fastening device according to the invention is also suitable for Installation of horizontally arranged profiles, especially when using the leg plates a profile is connected with an outer wall surface with the Bottom edges and / or the top edges of the leg plates are aligned or over this protrudes, so that the outer wall surface as a mounting surface for a Facade elements supporting profile can serve. It is preferably with the Leg plates connected profile formed as a U-profile and overlaps the Upper edges of the leg plates.

A first embodiment of the fastening device according to the invention is shown in Figure 1 and has a U-shaped holder 1, two flat Leg plates (2) and a U-shaped profile 3. How schematic indicated, the fastening device is suitable for holding profiles 4, for example as a box profile 4a, as a U-profile 4b or as a hat profile 4c can be trained.

The U-shaped holder 1 has one intended for bearing against a building wall Base plate 5 and two leg extensions 6 projecting perpendicularly therefrom on. The base plate 5 is provided with stiffening beads 7 for stabilization.

The leg extensions 6 are adjacent to the base plate 5 two below each other arranged vertical slots 8. At a distance from the vertical Slits 8 is a specially shaped through opening at medium height 9 provided that a large width at the upper end, one at the lower end smaller width and a the transition between the large width and the has small width producing slope 10. Above and below the Feed-through opening 9 are each a vertical slot with a rectangular opening cross-section.

The associated flat leg piece 2 consists of a rectangular Sheet metal plate and has front, i.e. pointing to the U-shaped holder 1 Edges two curved lugs 12 in the form of an L, with the free Legs of the approach 12 shows approximately parallel to the plane of the leg plate 2. The height of the curved lugs 12 is less than the free height of the vertical Slots 8, which are intended to receive the curved lugs 12.

This ensures that the curved lugs 12 in the vertical Slits 8 are vertically movable.

With a horizontal distance from the curved lugs 12 is on the middle Height of the leg plate 2 by punching and bending an offset 13 trained, which - as can be seen in particular Figure 2 - as about L-shaped part perpendicular to the plane of the leg plate 2 with a narrow one Neck portion 15 and a wider head portion 14 extends, the transition between neck part 15 and head part 14 is effected by a bevel 16.

Above and below the bend 13 there are two to each other punched and angled guide pieces 17.

At the rear end, the leg plate 2 is provided with holes 18 which to facilitate the attachment of the profiles 4, for example by means of self-tapping Screws, serve.

The U-profile 3 is dimensioned so that its legs 19 vertically downwards show, the two leg plates 2 overlap and so with these leg plates 2 are connectable. The horizontal middle section 20 the U-profile is provided with a stamped and bent clamping spring 21, in a horizontal manner in a manner known per se profile can be inserted for preliminary determination until it is final, for example by screws or rivets, with the horizontal part 20 of the U-profile is connected.

Figures 2 to 4 illustrate the assembly of a leg plate 2 on the U-shaped holder 1. For this, the leg plate 2 is bent with the front Approaches 12 pointing outwards obliquely into the interior of the U-shaped Holder 1 performed, as shown in Figure 2. The curved Lugs 12 are inserted into the associated vertical slots 8. The Leg plate 2 is then about a vertical axis in the area of the curved Approaches 12 against the associated leg extension 6 for flat contact pivotable when the leg plate 2 is held at a height in the the head piece 14 of the bend 13 through the larger width of the through opening 9 can pass through, as shown in Figure 3. In this position are both the curved lugs 12 and angled guide pieces 17 each at about the top of the vertical Slots 8 and the elongated holes 11. When the head 14 completely through the lead-through opening 9 has passed through, i.e. the leg plate 2 lies flat against the leg extension 6 of the U-shaped holder 1, the Leg plate 2 slide down by pressure or by its own weight and assume the position shown in Figure 4. Stands out in this position the neck of the bend 13 due to the smaller width of the through opening 9, while the wider head piece 9 protrudes horizontally and thus securing the leg plate 2 in the horizontal System on the associated leg extension 6 of the U-shaped holder causes. The downward movement of the leg plate 2 both move the curved lugs 12 in the associated vertical slot 8 as also the angled guide pieces 17 in the associated elongated hole 11 downward. The flat contact of the leg plate 2 is in this position on the leg extensions 6 of the U-shaped holder 1 both through the curved Approaches 12 in connection with the limitation of the associated vertical Slot 8 and through the head piece 14 of the bend 13 in connection guaranteed with the limitation of the through opening 9. An uneven one Relative vertical displacement absorbing thermal expansion between leg plate 2 and U-shaped holder is due to the oversizing the vertical slots 8, the slots 11 and the training the through opening 9 ensures. The bevel 16 of the bend 13 prevents in connection with the slope 10 of the through opening 9 a possible blockage of the vertical mobility by jamming after hiking up the head piece 14 within the through opening 9th

FIG. 5 illustrates the mounted fastening device according to FIG. 4 a building wall 22. Is used for attaching the U-shaped holder 1 uses a dowel head 23 which has a spherically shaped back and is rotatable relative to the dowel body, any inclinations can be adjusted or compensated by the fastening device.

Figure 5 illustrates that the flat leg pieces 2 in one with the Leg approaches 6 overlapping area are kept, which is different from the curved lugs 12 to the rear over the angled guide pieces 17 extends. The attachment of a is shown schematically in FIG vertical box profile 4a, which extends over several, vertically one below the other attached fastening devices extends and on which a facade panel 24 is attached. The box profile 4a is from the two leg plates 2 overlapped on the outside on two opposite walls. By doing Overlapped area are 18 connecting means with the help of the holes set, for example in the form of self-tapping screws.

FIG. 6 shows a further embodiment of the fastening device according to the invention, in which the leg plate 2 'compared to that shown in Figure 5 Leg plate 2 is formed much longer to a larger Bridge the distance between the facade panel 24 and the building wall 22. The U-profile 3 which is not required in the embodiment according to FIG. 5 is here to stabilize the leg plate 2 'as a cross-connection between the Leg plates 2 'provided.

In the exemplary embodiment shown in FIG. 7, the U-profile 3 becomes this used with the fastening device according to the invention in unchanged Mounting on the building wall 22 also includes a horizontal support profile 25 to be carried when facade panels 24 are attached to horizontal support profiles 25 should be. In this case, the U-profile 3 not only stiffens the fastening device in the area of the leg plates 2 but also serves Attachment of a horizontal leg of the horizontal profile 25 that here is designed as an L-profile.

In the further exemplary embodiment of the invention shown in FIG a leg plate 2, 2 'is provided, in which instead of the elbow 13 of In the first exemplary embodiment, an offset 13 'is provided, which is designed as a curved one is formed elastic part and with a vertical recess 26 cooperates instead of the through opening 9 of the U-shaped holder 1. Of course, such interlocks can be made with or Realize in numerous variations without elastic elements.

The exemplary embodiments described clarify that with the inventive Fastening device both vertical and horizontal Retaining profiles for facade panels can be attached without the type of Fixing the critical torques around a vertical axis in the building wall be initiated.
