Description

The invention relates to a device and a method for producing a wall or ceiling panel with a single or multiple curved wall or ceiling surface. Furthermore, the invention relates to a curtain wall or ceiling panel with a single or multiple curved wall or ceiling surface.

Freely shaped wall or ceiling surfaces indoors or outdoors can be easily displayed with the aid of computer-aided drawing programs, but are difficult to implement on the construction site. This applies in particular to doubly curved envelope surfaces made of a pre-hung plate material. For this purpose, the envelope surfaces are generally subdivided into individual triangular surfaces which determine the blank of the plate material. The more fragmented the individual surfaces are, the less noticeable are the differences in pitch between the individual plates. At the same time, however, increases the cost of the substructure, by means of which the plates are attached to the respective on-site support.

From the utility model DE 20 2008 015 447 U1 is exemplified a room trim arrangement with a substructure and on the substructure room side fixed, a dome-shaped cladding surface forming cladding panels known to be relatively easy to assemble. The cladding panels each have the form of a Surface segment of a sphere or an ellipsoid, that is, a shape adapted to the later shape provided in the final assembled state. In addition, the cladding panels can be made flat because the final shaping is done during assembly of the cladding panels on the substructure. The substructure for attaching the cladding panels to an on-site substrate comprises a plurality of bracing rings of a sheet metal material, which are arranged concentrically and suspended at different heights from the ceiling. The bracing rings thus form the "latitude" of the dome. The "longitudes" are formed by pre-bent hat profiles, which are also made of a sheet metal material and bolted to the bracing rings over bendable struts. The cladding panels can then be attached to the hat profiles, whereby the cladding panels are bent into shape.

From the DE 90 04 887 U1 Furthermore, an apparatus for fastening clothing panels, in particular wallcovering panels, to a substructure is known. The substructure comprises horizontal support profiles are hung in the secured by means of clamping elements holder, which are attached to the back of the clothing elements. The horizontal support profiles are attached to vertical T-profiles, which in turn are mounted by means of brackets on a shell wall.

The WO 2009/029911 A1 In addition, a device for attaching cladding panels to a substructure can be seen, which allows a variable length and / or angle adjustment. For this purpose, the device comprises a first pin, which interacts with a second pin to form a joint.

Based on the above-mentioned prior art, the present invention seeks to further simplify the production of a curtain wall or ceiling panel with a single or multiple curved wall or ceiling surface.

To solve the problem, the device with the features of claim 1 and the method with the features of claim 15 are proposed. Advantageous developments are shown in the respective subclaims. Furthermore, a wall or ceiling cladding with the features of claim 14 is given.

The proposed for producing a curtain wall or ceiling panel with a single or multiple curved wall or ceiling surface device comprises a first component for direct or indirect attachment to an on-site base and at least one connected to the first component or connectable further component to the immediate or indirect admission of a flat wall or ceiling paneling element. In this case, the first component and the further component act together forming a joint, so that the further component is rotatable or pivotable relative to the first component. The rotatability or pivotability of the further component relative to the first component allows a direct or indirect recording of a flat wall or ceiling paneling element in a position which is tilted relative to the on-site background. The tilt angle is freely selectable within an angular range over which the further component is rotatable or pivotable. If the flat wall or ceiling cladding element is guided over a plurality of "further" components twisted or pivoted to different degrees and fastened directly or indirectly thereto, a deformation of the flat wall or ceiling cladding element is achieved which leads to a curved wall or ceiling surface. In this way even wave-shaped wall or ceiling surfaces can be realized. The only requirement is that the flat wall or ceiling cladding elements are already bent or can be bent over the respective radius of curvature. As a surface wall or ceiling trim elements are conventional construction panels. For indoor use, for example, gypsum plasterboard come into question. These can be filled and painted after assembly, creating a seamless surface. In the exterior area, in particular facade panels with a finished surface or plaster base panels, in particular mineral plaster base panels or wood-based panels, can be used as flat wall or ceiling paneling elements. In addition, the use of membranes, films, nonwovens, fabrics and the like as a surface wall or ceiling cladding elements is possible, both indoors and outdoors.

With the aid of the device according to the invention, supporting structures can be made for a large number of freely shaped, in particular one or more times curved Create enveloping surfaces. It can be realized with only one component different curvature angle by the component is rotated or pivoted to different degrees. If a plurality of rotatable or pivotable components spaced apart from each other and mounted at different distances to the on-site support, so that the rotation or pivot axes are aligned parallel to each other, arises during clamping of the envelope of the optimal rotation or tilt angle by itself. In this way, the production of freely shaped envelope surfaces is significantly simplified. In addition, burr-free curved surfaces can be formed with the aid of the device according to the invention. This means that particularly high quality single or multiple curved wall or ceiling surfaces can be realized.

The distances of the rotatable or pivotable components to one another and to the on-site substrate are preferably predetermined by a plurality of "first" components of the device according to the invention fastened directly or indirectly to the on-site substrate. The "first" components may be the same or different. In order to realize different distances of the "other" components to the on-site background, only the location of the several identically designed "first" components with respect to the on-site background must be varied.

In a further development of the invention it is proposed that the first and the further component of the device according to the invention are connected via a plug connection or connectable. This means that the components of the device are already connected when they reach the construction site, or delivered individually to the site and connected only on site. The latter has the advantage that the transport and / or storage of the device is simplified or become. The connection on site via a plug connection is also easy to implement, since this tool is not required. Ideally, the connector is produced with one hand, so that in particular the assembly is simplified overhead. Furthermore, the Plug connection of the components easy disassembly of the device, should this be necessary.

According to the invention, the first component is designed as a flat and / or elongated body with at least one edge-side recess, which is executed undercut for the formation of peg-like portions. Due to its shape and function, therefore, the first component can also be referred to as a support rib. The first component or the supporting rib is preferably fastened directly or indirectly in a vertical arrangement via an additional holding device on the on-site substrate, so that the at least one edge-side recess comes to rest on the front edge of the first component or the support rib facing away from the substrate. About the edge-side recess can then be easily connected to another component with the first component or the support rib. Characterized in that the edge-side recess is executed undercut, two pin-like sections are released, which together form a pivot bearing for the further component. The further component is accordingly rotated or pivoted about the two pin-like sections of the first component.

Since the pin-like portions of the first component after completion of the wall or ceiling panel a high load, in particular by tensile forces may be exposed, is proposed to optimize the stress distribution that the pin-like sections - in the plan view of the first component - at least partially arcuate , Preferably, the pin-like portions at least in the region of their base on a curved course, so that rectangular transitions are avoided.

The connected to the first component or connectable further component according to the invention has two mutually parallel legs, in each of which a sleeve-like recess for connection to the first component or to

Receiving the two pin-like portions of the first component is formed. The diameter of the two bush-like recesses is therefore preferably adapted to the maximum width of the two peg-like recesses. As a result, the rotatability of the further component with respect to the first component is ensured around the two pin-like sections.

The two legs of the further component are preferably connected via a web, so that the further component is designed substantially U-shaped. The bridge is used for direct or indirect recording of a flat wall or ceiling paneling element. The wall or ceiling paneling element is this applied directly or indirectly to the web and attached to this with the aid of mechanical fasteners, such as screws. Preferably, at least one recess for receiving a fastening means is already formed in the web. In this way, the mounting of the wall or ceiling trim elements can be further simplified.

Preferably, the distance between the two legs of the other component is greater than the distance between the two pin-like portions of the first component. This ensures that the two pin-like portions of the first component securely engage in the socket-like recesses of the two legs of the other component. The form-fitting also causes a position assurance of the other component with respect to the first component, wherein the rotatability of the further component is maintained relative to the first component.

As a further development measure, it is proposed that the width of the peripheral recess of the first component in the region of the undercut be greater than the distance between the two legs of the further component. This means that only a form fit in a direction perpendicular to the axis of rotation of the other component can be effected via the pin-like sections engaging in the bush-like recesses. In a direction parallel to the axis of rotation remains further component relative to the first component slidably. The displaceability of the further component allows the production of the desired connector. For this purpose, only a pin-like portion of the first component is initially introduced into a bush-like recess of the further component. The further component is thereby completely pushed onto the peg-like section and then pivoted into the edge-side recess of the first component until the further bush-like recess of the further component comes to lie in register with the further peg-like section of the first component. Subsequently, by a displacement of the further component in the opposite direction of the further pin-like portion can be brought into engagement with the further bush-like recess.

In a further development of the invention is also proposed that the two legs of the other component are rounded end and rotatably guided in guide grooves of the first component. About the guide grooves a positive connection in a direction parallel to the axis of rotation of the other component can be achieved, so that after the production of the desired connector between the further component and the first component a position assurance of the other component is effected. The guide grooves in the first component are for this purpose guided parallel to the two legs of the further component, wherein the distance between the two guide grooves substantially corresponds to the distance between the two legs and / or wherein the groove width of the guide grooves of the material thickness of the legs is adjusted.

The end-side rounding of a leg of the further component preferably has a diameter which corresponds to the width of the leg. The rounding therefore forms a semicircle, which is preferably arranged concentrically to the bush-like recess of the leg. This ensures that the guided in the guide further component at least over an angular range of 180 ° relative to the first component is rotatable or pivotable.

Furthermore, it is proposed that the two legs of the further component in each case have a slot which extends radially with respect to its bush-like recess and which is open to receive the first component towards the outside. The angular position of the slots determines the angular position of the other component in the production of the connector with the first component. For when slipping or pushing the other component on the pin-like portions of the first component, the slots must be aligned so that they lie in a plane with the first component, so that the first component can be brought into engagement with the slots. Preferably, the angular position of the slots with respect to the bush-like recess is selected such that they run parallel to the web of the further component. To attach or postpone on the first component therefore further component must be placed in an angular position, which corresponds to an extreme position and is therefore suitable only for assembly purposes. If subsequently the slots are brought into coincidence with the guide grooves of the first component, the further component can be brought into an angular position by turning or pivoting, which is realistic for producing a single or multiple curved wall or ceiling surface and in which the further component is positively connected via the pin-like sections and / or the guide grooves with the first component.

Preferably, the two legs of the further component each have a sleeve-like recess widening radially extending slot. The slot increases in a certain angular position of the other component with respect to the first component, the game between the two components, so that a balance of manufacturing tolerances is possible, which facilitates the production of the connector. Preferably, the slot widening the bushing-like recess is arranged on a common longitudinal axis with the slot open to the outside for receiving the first component during the attachment or pushing on of the further component. In this way, in particular the plugging or postponement of the further component on the first component before the complete pivoting into the edge-side recess of the first component.

According to a further preferred embodiment of the invention, the first component - in plan view - on a first and a second longitudinal edge, at least in sections, not parallel to each other. This means that the width of the first component or the support rib varies. About the varying width of the first component or the support rib, the distances of the other components connected to the component or the support rib can be varied to the on-site background. In this way, a curvature can be introduced into the wall or ceiling surface, which extends transversely to a first curvature which is effected via differently twisted or swiveled further components, which are each spaced from each other and arranged at different distances from the on-site substrate.

Alternatively or additionally, it is proposed that the first component-in plan view-has at least one longitudinal edge which, at least in sections, has a substantially arcuate course. "Essentially arcuate" in this context means that the arcuate course can also be formed by a plurality of straight lines which together form a polygonal course. If only one longitudinal edge has an arcuate course, the first component or the support rib is to be oriented in such a way that the arcuately extending longitudinal edge points away from the on-site background. The arcuate longitudinal edge has in this case, the edge-side recesses for receiving the other components. The other components received in the recesses come to rest in this way at different distances to the on-site background, so that a curvature is effected in a further spatial direction.

Advantageously, the first component and / or the second component is or are made of metal, in particular of aluminum, galvanized steel or stainless steel. Metallic materials are particularly strong and thus loadable, especially in the pulling direction, so that they are ideal for the intended use. Furthermore, the aforementioned materials are insensitive to moisture, so that they can be used outdoors to produce a curtain facade with a single or multiple curved facade surface. Aluminum is preferably used, since in this way a comparatively lightweight support structure is created.

It is also proposed that at least the further component of the device according to the invention is a stamped / bent part. The execution as a punched / bent part lowers the production costs.

Particularly preferred is or are the first component and / or the further component made of a sheet metal material with a sheet thickness of 1-10 mm. The sheet thickness is chosen according to the static requirements. For example, the sheet thickness can be 4 mm.

In addition to the two components already described, namely the first component or the support rib and the further component, which is referred to below as a connector, the device according to the invention may further comprise at least one plank-like component which is pre-bent and / or flexible. Because the plank-like component serves as an intermediary between the surface-mounted wall or ceiling paneling element to be attached and the support structure attached to the on-site support. Preferably, a plurality of plank-like components are provided, which are mounted transversely to the support ribs of the support structure. In this way, a spatial grid structure is created, which is one or more curved after clamping an envelope surface of flat wall or ceiling paneling elements.

In order to serve as an intermediary, the plank-like components are attached to the connectors, which in turn are rotatably or pivotally connected to the support ribs. The connectors thus form the nodes of the spatial grid structure. However, the plank-like components can be mounted not only at a distance, but also adjacent to each other, so that no grid structure is formed, since the plank-like components form a closed surface on the support ribs.

With regard to the preferred application of the device according to the invention, a curtain wall or ceiling cladding with a device according to the invention for producing a single or multiple curved wall or ceiling surface is also proposed. The wall or ceiling cladding is formed from flat wall or ceiling cladding elements, which are attached by means of the device directly or indirectly to an on-site support. Under "flat wall or Deckenbekleidungselementen" are understood to be conventional construction panels, panels and flexible surface elements, such as membranes, films, nonwovens, fabrics and the like. Prerequisite for use as a flat wall or ceiling paneling element in a wall or ceiling panel according to the invention is merely that the flat wall or ceiling paneling element can bend, unless it is already - bent according to a predetermined radius of curvature. The curtain wall or ceiling cladding can be used both indoors for interior design, as well as in the exterior of the facade design. Due to the use of the device according to the invention in the production of wall or ceiling paneling one or more curved wall or ceiling surfaces can be realized. The device according to the invention forms - alone or in combination with a holding device for the indirect Attachment to an on-site substrate - a support structure, to which the flat wall or ceiling paneling elements are attached.

To solve the problem mentioned above, a method for producing a curtain wall or ceiling panel with a single or multi-curved wall or ceiling surface is further proposed using a device according to the invention. In the method, at least one first component or a support rib of the device is attached directly or indirectly, for example via a holding device, to an on-site substrate. Furthermore, at least one further component or a connector of the device is connected to the first component or the support rib, so that it is arranged externally and with respect to the first component rotatable or pivotable. By rotating or pivoting of the further component or connector can therefore be tilted a support surface for direct or indirect recording of the flat wall or ceiling paneling element with respect to the on-site background. In this way, different degrees of curvature of the wall or ceiling surface can be realized.

According to a preferred embodiment of the invention, a plurality of first components or supporting ribs are fastened in a parallel arrangement directly or indirectly on the on-site substrate and connected several further components or connectors, each with a first component or a support rib, so that the other components or connectors common axes are arranged, which are preferably parallel and transverse to the first components or supporting ribs. In this case, the distances of the individual nodes to the on-site background vary, so that an area spanned over the nodes is curved one or more times. The varying distances can be realized via the shape of the support ribs and / or over their distance to the on-site background.

Advantageously, the other components or connectors are connected prior to assembly of the flat wall or ceiling cladding elements with plank-like components, so that a lattice structure is formed on the plank-like components in connection with the first components or the support ribs. The other components or connectors form the nodes of the grid structure.

To further simplify the method, it is proposed that a further component or a connector is connected by means of a plug connection with a first component or a support rib. The device according to the invention, which forms the support structure or at least a part of the support structure of the wall or ceiling panel to be produced, can be mounted without tools in this case.

The representation of the Fig. 1 show elements of a curtain wall construction, which comprise surface pre-bent wall cladding elements 5 and a device 1 for fastening the wall cladding elements 5 to an on-site substrate 20. The on-site substrate 20 is formed in this case by a masonry wall. The device 1 not only serves to fasten the wall cladding elements 5 to the on-site substrate 20, but also to produce a doubly curved wall surface 2. For this purpose, the device 1 comprises a first component 3, which forms a support rib, and a further component 4, hereinafter as a connector referred to as. The connector 4 forms a joint 6 together with the support rib 3 (see FIG Fig. 2 ), so that after the assembly of the device 1, the connector 4 with respect to the supporting rib 3 remains rotatable or pivotable. To form the joint 6, the support rib 3 has an edge-side recess 7, which is executed undercut, so that two pin-like portions 8 are released (see Fig. 4 ). On these two pin-like portions 8 of the connector 4 is attached, which for this purpose has two parallel legs 9, each with a sleeve-like recess 10 (see Fig. 7 ).

How further the Fig. 1 can be seen, the two legs 9 of the connector 4 are connected via a web 11, which serves to receive and attach a plank-like member 18. The attachment takes place with the aid of fastening means 19, which are in the present case designed as screws. To accommodate the fastener 19 4 recesses 12 are provided in the web 11 of the connector (see also Figures 2 . 7 and 9 ).

The plank-like component 18 is oriented perpendicular to the supporting rib 3. The wall cladding elements 5 are then fastened to the plank-like component 18, in which case fastening means 19 can again be used. The plank-like component 18 is not absolutely necessary and therefore represents only an optional component of the device 1 according to the invention. Because depending on the specific design of the flat wall or ceiling cladding elements 5, these can also be attached directly to the connector 4.

Another optional component is the holding device 21. It serves for the indirect attachment of the supporting rib 3 on the on-site substrate 20, for example, to realize large distances between the wall covering and the on-site substrate 20, the - if necessary - sufficient space for the arrangement of an insulating layer and an air layer for ventilation of the Create wall cladding (not shown). The holding device 21 is presently designed as a bracket.

How can be realized with the aid of the inventive device 1 curved wall or ceiling surfaces 2, in particular the Fig. 11 be removed. This shows a lattice structure which is formed of a plurality of parallel and spaced a support ribs 3 and a plurality of parallel and arranged at a distance b plank-like components 18, wherein the plank-like components 18 extend perpendicular to the support ribs 3. In the intersections, the fastening of the plank-like components 18 to the support ribs 3 takes place via a connector 4 (not shown). The support ribs 3 have straight longitudinal edges 16, 17 (rear support rib 3) or arcuate longitudinal edges 16, 17 (the rear support rib 3 upstream support ribs 3), wherein the radius of the arch shape is smaller towards the image foreground. The arch shape of the support ribs 3 has the consequence that the distances c of the support ribs 3 and thus also the connected to the support ribs 3 connector 4 to the on-site substrate 20 vary. As a result, the plank-like components 18 fastened to the connectors 4 are forced into an arcuate shape which causes a curvature of the enveloping surface which runs perpendicular to the curvature or arc shape of the support ribs 3. If sheet-like wall cladding elements 5 are fastened to the plank-like components 18, a wall surface is created which is doubly curved (not shown).

The Fig. 12 are design variants refer to, which can also be realized by means of the device 1 according to the invention. Fig. 12a ) shows, for example, a lattice structure raised from the device 1 according to the invention, which leads to the formation of a flat wall surface 2, when planar wall cladding elements 5 are attached thereto. The Fig. 12b ) shows a lattice structure that is doubly curved and thus the lattice structure of Fig. 11 equivalent. A lattice structure for making a simply curved

Wall surface shows Fig. 12c ), the curvature being comparatively strong. The Fig. 12d ) is a grid structure for a strongly curved in two directions wall surface 2 can be seen. In addition, a variety of other configurations of curved wall or ceiling surfaces 2 can be realized by means of the device 1 according to the invention, but not all of which can be represented in connection with the description of the invention.

The following are based on the FIGS. 2 to 8 the essential components 3, 4 of the device 1 according to the invention are described. The optionally usable plank-like component 18 is then based on the FIGS. 9 to 10 explained in more detail.

The Fig. 2 shows the section of a support rib 3 in the region of a peripheral recess 7, in which a connector 4 is inserted in such a way that it is rotatable relative to the support rib 3. By turning the connector 4 relative to the support rib 3, the web 11 of the connector 4 is brought into a tilted position relative to the on-site substrate 20. An active twisting of the connector 4 is not necessary because it aligns itself when a plank-like component 18 and / or a flat wall or ceiling covering element 5 is attached thereto or are. For receiving fasteners 19 11 recesses 12 are provided in the web.

By fastening a plank-like component 18 and / or a flat wall cladding element 5 on the connector 4 act - yes after the radius of curvature of the plank-like member 18 and the wall or ceiling cladding element 5 - high tensile forces on the connector 4, which in turn to high voltages in the pin-like sections 8 of the support rib 3 can lead. In order to achieve an optimal stress distribution, the peg-like sections 8 are slightly curved in the area of their base (see Fig. 4 ). The arch shape is outboard by an oblique achieved straight line, which is easier to manufacture. Inside the arch shape is created by a polygonzugartigen edge course.

Again Fig. 2 it can also be seen, the support rib 3 and the connector 4 form a hinge 6 in the manner of a hinge. The connector 4 is held in a direction perpendicular to the axis of rotation via the positive connection with the pin-like portions 8 of the supporting rib 3. In a direction parallel to the axis of rotation cause in the supporting rib 3 formed guide grooves 13, which extend the edge-side recess 7, a positive connection (see also Fig. 4 ). In order to obtain the rotational mobility of the connector 4 relative to the support rib 3, the recorded in the guide grooves 13 ends of the legs 9 are rounded. The rounding forms in each case a semicircle, which is arranged concentrically to the respective bush-like recess 10.

The components 3, 4, ie the support rib 3 and the connector 4 of the device 1 according to the invention, are preferably connected on site to the site in order to simplify the transport or storage. This means that the joint 6 is only formed on site at the construction site. Ideally, the connector 4 is simply attached to the supporting rib 3 for this purpose. To make this possible, the two legs 9 of the connector 4 each have a first slot 14, which extends parallel to the web 11 and is open to the outside (see also FIGS. 5 to 7 ). Further, in each case a further slot 15 is provided in the legs 9, which also extends parallel to the web 1, but is open to the bush-like recess 10 (see also FIGS. 5 to 7 ). For attaching the connector 4 on the support rib 3, a first pin-like portion 8 of the support rib 3 is first threaded into a socket-like recess 10 of the connector 4. For this purpose, the connector 4 is held obliquely and oriented with respect to its angular position such that the support rib 3 engages in the slot 14 (see FIG FIGS. 8a) and 8b )). The slot 15 provides the necessary clearance to push the connector 4 in an inclined position on the pin-like portion 8. Subsequently, the connector 4 is in the edge side Recess 7 of the support rib 3 swung until the other female recess 10 of the connector 4 is brought into coincidence with the other peg-like portion 8 of the support rib 3 (see Fig. 8c )). In this position, the connector 4 can now be pushed onto the further pin-like portion 8, so that both pin-like portions 8 of the supporting rib 3 are in engagement with the bush-like recesses 10 of the connector 4. The angular position of the connector 4 initially remains unchanged until the slots 15 come to rest at the level of the guide grooves 13 (see Fig. 8d )). When this position is reached, the connector 4 can be rotated so that the rounded ends of the legs 9 are in engagement with the guide grooves 13 (see Fig. 8e )). The angular position of the slots 14, 15 of the connector 4 is selected such that the web 11 of the connector 4 is aligned parallel to the support rib 3 when plugging onto the support rib 3. This corresponds to an angular position of the connector 4, which lies outside a practically relevant angle range for producing a curved wall or ceiling surface 2.

The essential components 3, 4 of the device 1 according to the invention can in particular be made of a metallic material, for example of aluminum. The base material may be a metal sheet which is punched and possibly bent to produce the components 3, 4. There - as in the Fig. 3 shown - the component 3 is executed flat, forming by bending can be omitted. The plurality of peripheral recesses 7 for receiving the components 4 can be produced by punching or cutting, in particular by laser cutting. In the longitudinal direction, two metal sheets can be pushed overlapping to extend the support rib 3 and connected to one another in the overlapping region 23, for example screwed, riveted, welded and / or adhesively bonded. The component 4 is preferably a stamped / bent part, since such a cost can be produced from a metal sheet. Like in the Fig. 6 shown, first flat punched parts are prepared and then bent along the lines 22, so that in the Fig. 7 receives shown connector.

The optionally usable plank-like component 18 may also be made of a metal sheet or of another material. The only prerequisite is that the plank-like component 18 is flexible or is already bent according to its final shape. In order to increase the flexibility of the plank-like component 18, this may have regions 24 in which the cross-section of the component 18 is reduced (see Fig. 10 ). In addition, the plank-like member 18 may have recesses 12 for receiving fasteners 19 to facilitate on-site assembly on site (see Fig. 9 ). In particular screws can serve as a fastening means 19, with which the plank-like component 18 is fastened to a connector 4 and / or a wall or ceiling covering element 5 is connected to the plank-like component 18 (see Fig. 10 ).
