Description

The invention relates to a multi-part holding device for attaching plate-shaped wall or ceiling clothing elements to an on-site substrate with the features of the preamble of claim 1. Furthermore, the invention relates to a method for producing such a holding device.

Holding devices of the aforementioned type can be used in particular for the formation of curtain-type, ventilated facades. Here, plate-shaped facade elements are hung with the aid of the holding device in front of a load-bearing wall construction, which is usually insulated on the outside. However, since the holding device is to be attached to the load-bearing wall construction for static reasons, at least the distance created by the insulating layer between the supporting wall construction and the plate-shaped facade elements must be bridged by means of the holding device. Depending on the Dämmschichtdicke, which is to be bridged, the projection of the holding device can be considerable. If a rear ventilation of the façade is also required for structural-physical reasons, the distance or the projection of the holding device increases by a continuous air layer arranged between the insulating layer and the plate-shaped facade elements.

Since the lever law is applicable, the load increases with increasing distance or with increasing projection of the holding device. Should also Particularly heavy facade elements, such as those made of natural stone or glass, are attached to an on-site support, the fixture must have sufficient mechanical stability to ensure the load transfer into the ground.

A high mechanical stability, for example, have angle-shaped holding devices made of metal. From the DE 93 01 278 U1 goes by way of example a wall bracket, which is designed as a stable metal angle. A first leg of the metal angle is used for installation and attachment of the holding device on the construction site. About the other leg, the holding device can be connected to a holding profile, which is presently T-shaped and serves to receive plate-shaped wall or ceiling clothing elements.

A development of the angular wall bracket is from the DE 297 03 013 U1 known. The wall holder is here made in two parts to allow a simple way to a distance adjustment. The wall holder comprises an angle-shaped wall part and an extension part. The wall part has a first leg for engaging and fastening the wall holder on a wall and a second leg for connection to the extension part. By shifting the parts against each other or by using different length extension parts can be set any distance from the wall. Further, between the wall part and the extension part, a heat-insulating material can be arranged to achieve a thermal separation.

From the DE 20 2007 016 621 U1 is a multi-part facade substructure with a slide holder and a T-shaped base holder known. After attaching the base holder to a wall, the slide holder can be connected by simply sliding it with the basic holder.

From the EP 2 365 157 A1 Furthermore, a multi-part holding device with a base body shows that a contact surface for engagement with a wall and Has at least one receiving area for receiving a spacer element. The spacer element is inserted perpendicular to the wall surface in the receiving area.

In addition, from the DE 296 09 145 U1 discloses a device for suspending ceilings, comprising a sheet-metal profile body and a length-adjustable suspension rail.

Based on the above-mentioned prior art, the present invention seeks to provide a holding device for attaching plate-shaped wall or ceiling clothing elements, which allows a distance adjustment and at the same time has an increased load capacity. To solve the problem, the holding device with the features of claim 1 is proposed. Advantageous developments of the invention can be found in the dependent claims. Furthermore, a method is specified, by means of which the holding device is simple and inexpensive to produce.

The proposed for attaching plate-shaped wall or ceiling clothing elements on an on-site support holding device is designed in several parts. It comprises a base part which can be fastened to the substrate and at least one boom part which can be connected to the base part. About the boom part, the holding device can be connected to a holding profile, which serves to receive at least one plate-shaped wall or ceiling lining element. The base part has an elongated base plate and at least one leg perpendicular thereto for connecting the base part to the boom part. The leg is offset from a first and a second longitudinal edge of the base plate in each case offset inwardly. That is, the base part in a side view is not L-shaped, but at least approximately T-shaped. The inwardly offset arrangement of the leg allows a substantially central loading of the base part when the boom part is connected to the leg of the base part. In this way, the load capacity of the holding device increases. This is especially true if the attachment of the base part takes place on the ground in imaginary extension of the leg or in alignment with the leg. For example, the attachment to the ground can be effected by means of screws and / or dowels, which are then preferably arranged so that they come to lie on an axis with the leg.

About the elongated base plate, the base part is able to support the ground. Preferably, the base part is oriented in the attachment to the ground in such a way that the longitudinal axis of the base plate coincides with the main loading direction. On a wall, the attachment is therefore preferably edgewise. The same orientation undergoes the leg, which is preferably parallel to Longitudinal axis of the base plate and / or runs parallel to at least one longitudinal edge of the base plate. In this way, a high dimensional stability of the base part in the loading direction is achieved.

In order to connect the cantilever part to the base part, this is preferably applied flat to a side surface of the leg of the base part. The actual connection can in turn be effected by means of mechanical fastening or connecting means, such as screws, rivets, bolts or the like. The boom part thus comes also upright, so that the load transfer over the entire height of the jib part takes place, which also has a positive effect on the load capacity of the holding device.

The multi-part design of the holding device allows the use of different length boom parts, so that a high variability can be achieved, since depending on the length of the boom part different distances or projections of the holding device can be realized.

According to the invention, the leg defines a recess formed in the base plate of the base part, which extends from the leg to a first longitudinal edge of the base plate. With this configuration, the production of the base part and thus the holding device can be simplified. Because in the production of the recess, the excess material can be used to form the leg. For example, the base plate can be slotted twice in the region of the first longitudinal edge, so that a tab is exposed, which only has to be brought by bending into a standing substantially perpendicular to the base plate position for the formation of the leg.

Furthermore, according to the invention, therefore, at least the base part of the holding device according to the invention is a stamped / bent part, since it can be produced as such easily and inexpensively.

Further preferably, at least the base part is made of metal. By using a metallic material, the robustness of the base part can be increased.

Furthermore, preferably at least the base part is made of stainless steel. Stainless steel does not corrode and is therefore particularly suitable for outdoor use, preferably in the façade area. At the same time stainless steel has a high strength, so that the base part is able to absorb high loads.

To increase the robustness of the entire holding device, it is proposed that the jib part is preferably made of a metallic material, in particular of stainless steel. In this way, a high strength or dimensional stability of the holding device is achieved at the same time.

Advantageously, the leg of the base part is arranged substantially centrally with respect to the width of the base plate. The central arrangement ensures an even load distribution. This applies in particular if the fastening means provided for fastening the base part to the substrate are arranged substantially centrally with respect to the width of the base plate, so that they come to lie on an axis with the leg.

For receiving a fastening means, by means of which the base part can be fastened to the substrate, the base plate preferably has at least one recess. The recess may be formed in particular in the form of a bore and / or a slot. As fastening means, for example screws and / or dowels can serve. In order to optimize the load capacity of the holding device, it is further proposed that the at least one recess is arranged centrally with respect to the width of the base plate. The load capacity is optimized in particular when the leg - as described above - also in the middle in With respect to the width of the base plate is arranged, so that the fastening means lie on an axis with the leg.

In a further development of the invention, it is proposed that the base plate has an upstand in the region of the second longitudinal edge. The upstand causes a stiffening, so that increases the dimensional stability of the base part by this measure. Preferably, the upstand extends over the entire length of the second longitudinal edge.

Further preferably, the leg of the base part has at least one recess for receiving a connecting means, by means of which the cantilever part can be connected to the base part. As a connecting means, at least one screw, a bolt, a rivet or the like can be used. The recess may be formed in particular as a bore and / or as a slot. A recess formed as an elongated hole has the advantage that the parts to be joined are displaceable relative to each other, for example, to compensate for manufacturing and / or assembly tolerances. Alternatively or additionally, it is proposed that a plurality of recesses are provided in a row arrangement, so that different distances of the jib part with respect to the ground can be realized via the choice of the recess.

Preferably, the base part has two legs spaced apart in the longitudinal direction, by means of which the base part can be connected to the boom part. By this measure, the contact area of the jib part can be reduced with the base part, resulting in a reduced heat transfer result. The stability of the holding device is not or at least not substantially impaired if the two legs including the distance have a total width which corresponds at least approximately to the width of the jib part.

Further preferably, the jib part has at least one recess, in particular in the form of a bore and / or a slot, for receiving a connection means by means of which the jib part can be connected to the base part and / or to a retaining profile. The recess or recesses are therefore preferably provided in at least one end portion of the cantilever part, which comes to rest on the base part or in contact with the holding profile. The arrangement of the recess or recesses is preferably carried out in such a way that they can be brought into coincidence with a recess of the leg of the base part.

In addition, it is proposed that the boom part in at least one end portion has a recess for releasing tab-like portions, via which the boom part with the base part and / or the retaining profile is connectable. The recess reduces the contact area of the cantilever part with the base part or the retaining profile, so that the heat transfer is reduced. The stability of the holding device is not or not substantially affected by this measure, if the total width of the tab-like sections including recess substantially corresponds to the width of the jib part.

In a further development of the invention, it is proposed that the jib part has at least one recess arranged in the surface. By the at least one recess arranged in the surface of the heat flow can be reduced via the boom part. In this way, holding devices can be realized which are passivhaustauglich. Similar to a truss girder, the load capacity of the jib part is not impaired by the at least one recess arranged in the surface. At the same time material and thus weight can be saved.

Alternatively or additionally, it is proposed that the holding device has at least one insulation strip for realizing a thermal separation of the base part from the on-site background includes. When mounting the holding device to the substrate, the insulating strip can be placed under the base part in order to realize a thermal separation. Alternatively, the insulation strips can already be factory-fixed to the base part, so that a step on the site is eliminated. Preferably, the insulating strip is made of sintered polystyrene, which has good thermal insulation values even in small thicknesses and is also sufficiently dimensionally stable to support the holding device on the ground.

In order to increase the dimensional stability of the jib part, it is proposed that the jib part has at least one deformed, in particular one or more folded or flanged edge region. Preferably, two mutually parallel edge regions are formed in this way. The deformed edge regions are preferably designed such that they engage around or engage behind the leg (s) of the base part, so that in addition a positive connection of the jib part to the base part can be achieved. In order to connect the jib part to the base part, in this case the jib part has to be pushed onto the leg (s) of the base part. In order to ensure a flat contact surface for the connection of the jib part with a retaining profile, the forming preferably takes place in such a manner that the deformed edge regions each come to rest on the same side of the jib part.

Furthermore, a method for producing a holding device according to the invention is proposed. The method is characterized in that the base part and / or the jib part of the holding device is / are produced in a punching / bending process from a metal sheet, in particular from a stainless steel sheet. The method enables a particularly simple and thus cost-effective production of the holding device according to the invention.

To form the at least one leg of the base part, a tab is preferably exposed by punching from the metal sheet, which is then bent, so that the tab is substantially perpendicular to the base plate. The base plate can be made to measure during the punching so that it has an elongated shape whose longitudinal axis is parallel to the leg.

Furthermore, a holding system for attaching plate-shaped wall or ceiling clothing elements to an on-site substrate with at least one holding device according to the invention and at least one holding profile is proposed. The retaining profile serves to receive the plate-shaped wall or ceiling clothing elements. In order to facilitate the connection of the holding profile with the holding device according to the invention, it is proposed that the holding profile is formed in cross-section T-shaped. The preferably centrally located web of the cross-sectionally T-shaped holding profile can be laterally applied to the jib part of the holding device and connected to this with the aid of connecting means, such as screws, bolts or rivets. The end arranged on the web flange, which serves to receive the plate-shaped wall or ceiling elements, comes to lie in this way parallel to the ground. The same applies accordingly for the plate-shaped wall or ceiling elements.

That in the Fig. 1 shown holding system is used to attach plate-shaped wall or ceiling clothing elements (not shown) on an on-site substrate (not shown). For this purpose, it comprises a holding device 1 according to the invention and a holding profile 2. The holding device 1 is designed in several parts and has a base part 3 and a jib part 4. The boom part 4 is connected to a leg 6 of the base part 3 via connecting means 11 and to the retaining profile 2 via connecting means 13. As connecting means 11, 13 are each screws.

The leg 6 is arranged perpendicular to a base plate 5 of the base part 3, so that the boom part 4 can be applied flat to the leg 6 for connection to the base part 3. The retaining profile 2 is T-shaped in cross-section, so that it can also be applied via a web 18 flat to the boom part 4. A flange 19 formed on the web 18 at the end can be connected to the plate-shaped wall or ceiling cladding elements.

For fixing the holding device 1 to an on-site substrate, the base plate 5 of the base part 3 is applied to the ground and fixed to the ground with the aid of fastening means (not shown). The fastening means may in particular be screws and dowels. About the base plate 5, the support of the holding device 1 takes place on the ground. To increase the dimensional stability of the base plate 5, this has a raised edge 9, which extends over the entire length of a longitudinal edge 5.2 of the base plate 5. In a parallel thereto extending longitudinal edge 5.1 a recess 7 is formed, which extends from the longitudinal edge 5.1 to the leg 6.

The recess 7 is due to the manufacturing process of the base part 3. Because this has been produced in a stamping / bending process from a metal sheet. In the method, the metal sheet forming the later base plate 5 was slit multiple times to expose a tab. The tab was then brought by bending in a vertical position to form the leg 6. The leg 6 comes to lie in this way substantially centrally with respect to the width (B) of the base plate 5 (see also Fig. 3b and Fig. 4b ).

The central arrangement of the leg 6 has the advantage that the load capacity of the holding device 1 increases. Because the leg 6 can (at least approximately) in alignment with the fastening means (not shown) are arranged, by means of which the base part 3 is fixed to the ground (see also Fig. 3b and Fig. 4b , the recesses 8 show the reception of the fasteners serve and are also arranged substantially centrally with respect to the width B of the base plate 5). In this way, all attachment and connection points lie in one plane (see Fig. 1 ), which significantly increases the load capacity of the holding device 1. At the same time the load is introduced into the base part 3 in the middle, so that a good load distribution is ensured.

In the Fig. 2 is the jib part 4 of the holding device 1 of Fig. 1 shown. This is also designed as a punched / bent part of a metal sheet. It has parallel edge regions 17, which have been deformed by bending, so that each results in a kind of flanging, so that the boom part 4 must be connected by sliding on the leg 6 with the base part 3. In opposite end regions, the jib part 4 recesses 12 in the form of holes and / or slots, which serve to receive the connecting means 11, 13 for connecting the jib part 4 with the base part 3 and the retaining section 2. The recesses 12 for receiving the connecting means 11 in order to connect the boom part 4 with the base part 3 are arranged in rows. The same applies to recesses 10, which are formed in the leg 6 of the base part 3 (see also Fig. 3a and Fig. 4a ), so that over this the projection of the jib part 4 is adjustable, for example, to compensate for unevenness of the ground. Further, a recess 14 in the boom part 4 is provided at the end, so that tab-like portions 15 are exposed, which serve the connection of the boom part 4 with the leg 6 of the base part 3. Because corresponding to the tab-like sections 15, the base part 3 has two legs 6 (see also Fig. 3a and Fig. 4a ). The recess 14 reduces the contact area and thus reduces the heat transfer.

The base part 3 of the holding device 1 of Fig. 1 is in the Fig. 3 presented in isolation, the Fig. 3a a side view and the Fig. 3b a plan view of the base part 3 show. The base plate 5 is elongated and has in the region of the longitudinal edge 5.1 two rectangular recesses 7, each of which Longitudinal edge 5.1 extend to a leg 6. Through the two recesses 7 three tab-like portions of the base plate 5 are exposed, in each of which a slot formed as a slot 8 is formed for receiving a fastening means by means of which the base part 3 can be fastened to the ground. Since a total of three recesses 8 are provided, which can be in the Fig. 3 shown base part 3 are used to form a fixed bearing.

An alternative embodiment of a base part 3 is in the Fig. 4 shown, again the Fig. 4a a side view and the Fig. 4b show a top view. This base part 3 also has two legs 6 and two recesses 7. However, the recesses 7 are arranged on the outside, so that they open to two sides. Furthermore, only one designed as a slot recess 8 is provided for receiving a fastening means. This is provided in the single tab-like portion of the base plate 5, which is released by the two recesses 7. Since only one recess 8 is provided, in the Fig. 4 shown base part 3 are used to form a sliding bearing.

Like in the Fig. 6 1, a holding system according to the invention has at least one base part 3 which can be used as a fixed bearing, as well as at least one base part 3 which can be used as a plain bearing. The plain bearing allows the compensation of thermally induced changes in length. The boom part 4 connected to the base part 3 serving as sliding bearing is accordingly connected to the retaining profile 2 via the recesses 12 formed as a slot. If the retaining profile 2 expands due to heating, this change in length can be compensated by means of the recesses 12 formed as a slot.

In the Fig. 5 the two main components of a holding device 1 according to the invention are each shown individually in a side view. For the production the connection, the boom part 4 is pushed onto the two legs 6 of the base part 3 and connected to the connecting means 11 (see also Fig. 7 ).

A further development of the invention is in the Fig. 8 shown. Here, the jib part 4 recesses 16, which are formed in the surface of the jib part 4. The recesses 16 minimize the heat flow through the boom part 4 and at the same time reduce the dead weight. Since the recesses 16 are formed in the surface, they have no or at least no significant influence on the statics, so that the high load capacity of the holding device 1 is maintained.

In the Fig. 8 the base parts 3 of the holding device are also underlaid with insulation strips 20, which serve to form a thermal separation. The insulation strips 20 can be used optionally and are otherwise optionally used in each holding device according to the invention. This means that the laying of insulation strips not only in the embodiment according to the Fig. 8 is possible.

By underlaying insulation strip 20, a thermal separation is effected, which significantly reduces the heat transfer between the base part 3 of the holding device and a substrate to which the base part 3 is attached. In this way, the formation of a thermal bridge can be counteracted.

The Fig. 9 are side views and plan views of the two main components of a holding device 1 according to the invention, wherein the left side shows a base part 3 for forming a fixed bearing and the right side a base part 3 for forming a sliding bearing. From top to bottom, the two first representations relate respectively to the boom part 4, the three following representations respectively show the base part 3. The bottom view again shows a view of the boom part 4. The boom part 4 of Fig. 9 has a comparatively large projection a ₁ . The 10 to 12 Boom parts 4 can be seen, with the the same base parts 3 can be combined, the projection a ₂ , a ₃ , a ₄ is lower. In this way, different distances of the plate-shaped wall or ceiling clothing elements can be realized to the ground. It must be used only the appropriate boom part 4. Since the projection a _{4 of} the jib part 4 of Fig. 12 is very small, this can also be used with base parts 3, the legs 6 are shortened. Since the shortened legs 6 come to lie on the side of the jib part 4, which is shown in the second view from above, they can not collide with a retaining section 2 attached to the jib part 4, since this is applied to the flat side of the jib part 4 , which is shown in the lowest representation (see also Fig. 6 ).

The basic parts 3 of the embodiments of Fig. 9 to 12 have in common that the base plate 5 has no upstand 9, but up to the legs 6 is executed. An upstand 9 is not mandatory. Further, the base plate 5 may be made of a thicker sheet metal material, so that a higher rigidity is achieved over this.

The invention is not limited to the illustrated embodiments. The invention also includes, for example, holding devices 1 whose base part 3 has only one leg 6. To minimize the heat transfer, however, two spaced-apart legs 6 are preferred. In addition, other modifications are possible, which are not shown.
