Grid construction

The invention relates to a grid construction for a ceiling and/or wall cladding.

A grid construction for wall and ceiling cladding 15

of the type mentioned above is known from DE 40 10 000 Al. It has profiles that are rectangular, polygonal, V-shaped or U-shaped in cross-section and consist of a strip with grooves on its back and along the grooves

folded, plate-shaped material. The 20

folded material is laminated on one side with a film.

A method for folding deformed components is known from DE 30 31 658 A1. With the help of a tool

2 B . .

A V-shaped groove is milled into a sheet coated with a film in such a way that when the V-groove is glued, the elastic two-dimensional deformation (bending) of the V-groove causes the

Surface areas form a three-dimensionally formed 30

A structural element similar to a folded structure is created.

From DE 296 00 213 Ul a beam grid ceiling is known, which consists of upwardly open, elongated profile elements

as well as with node elements for connecting several 35

profile elements in their intersection area. For this purpose, longitudinal profiles are provided which in the area of their two

The front ends have recesses that open downwards for hanging into the wall of a longitudinal profile.

The disadvantage is that this known solution, like the other two, does not provide any information on how to handle and process the individual elements of the grid construction.

From DE 22 36 470 A1 it is known to mill a V-shaped groove into a double strip, the depth of which saves reinforcement. However, this is specified in connection with a method for producing angle semi-finished products from composite panels that have a foam core that is coated on one of the flat sides with a glass fiber fabric that is embedded in a hardened mortar.

Based on a known grid construction of the type mentioned above, the invention is based on the object of improving the handling and processing of the individual elements of the grid construction.

According to the invention, this object is achieved by the features of claim 1.

The advantages achieved with the invention are in particular that the foil plate is left out by making the V-shaped groove in the hardboard plate. If the side walls are now folded up in the area of the V-groove, the varnish covering the foil plate breaks in a straight line over the entire length of the V-shaped groove. This creates a three-dimensional body whose side walls are precisely and easily provided with a veneer foil.

The folding boxes can be made from a first square hardboard board covered with a first foil board, into which two first parallel-running side walls are cut at a distance equal to the future dimensions of the side walls.

^ de V-shaped grooves and two second V-grooves running parallel to each other at right angles to these. By introducing the V-shaped grooves, the folding box is pre-formed in terms of its surface area. By breaking out excess material, a folding box of any configuration can be assembled.

The locking bars can be made from a second rectangular hard cardboard board covered with a second foil board, the longest side length of which corresponds to the length of the respective locking bar and into which a third V-shaped groove is made in the longitudinal direction and at a distance of one width of the future side walls. In this case, the respective locking bar is created only by erecting two

^g side walls against each other and a third side wall between them.

The first foil plate from which the folding boxes are made and the second foil plate from which the locking bars are made can be designed the same or different.

The folding boxes can have first recesses ^which can be introduced at least partially into the four adjacent side walls at a distance from their open side. The locking bars, on the other hand, can have second recesses which at least partially pass through the two adjacent side walls in the area of the two opposite open sides. Through this

go By making the recesses, a concealed connection of a folding box with at least one locking bar is possible.

An installation recess is arranged between the first recesses in the folding boxes. All types of supply lines can be pulled through these recesses.

From the open side of the folding box, a stabilizing cuboid can be arranged at least between two side walls, which can extend from the open side at least partially to the side wall opposite the open side. The stabilizing cuboids can increase the static strength of the folding boxes, because up to four locking bars can be attached to them, which apply forces to the folding box as a node element of the grid construction, which can come at it from different directions.

A tensioned fabric insert can be held on the stabilizing blocks and stretched between four folding boxes. This makes it possible to design the grid construction as a suspended ceiling in such a way that the ceiling above it and parts of the side walls are no longer visually perceptible to the observer.

An embodiment of the invention is shown in the drawing and is described in more detail below. It shows a schematic, perspective view:

grooves and recesses for a grid construction;

Fig. 2b shows a locking bar constructed from a further hard cardboard plate covered with another foil plate;

Fig. 4 a grid construction assembled from folding boxes and locking bars according to Fig. la to '3 as a suspended

Ceiling.

In Fig. la a square hard cardboard plate 4 is shown, which is covered with a film 5. Two parallel and intersecting V-grooves β are milled into the hard cardboard plate 4. The V-groove is made in such a way that its groove depth leaves space for the film plate and its tip rests on it.

As Fig. la shows, the grooves 6 are spaced apart so that they form side walls 11 of the appropriate size. The side walls 11 are arranged in a cross shape on the plate 4, 5. In their outward-facing ends, recesses 13 are cut parallel to one another, which have a V-like cross section and leave a tongue 14 between them. The recesses 13 cut through the hard cardboard plate 4 and the foil plate 5.

In order to be able to produce a folding box 1 from the configuration according to Fig. la, the free areas not used as side walls II are first broken out. Then the side walls provided with recesses 13 are tilted towards the side wall 11 in the center. Before this, the groove surfaces of the V-groove are provided with an adhesive 7. When the side walls 11 are tilted, the paint application of the foil plate 5 breaks through continuously and straight over the entire length. If all the side walls 11 are connected to one another,

A spatial body in the shape of a square is created from the outside, which is evenly covered with a foil on all sides. The foil plate 5 determines the external appearance of the folding box 11.

The manufacture of a locking bar is shown in Fig. 2a and 2b. The locking bar 2, like the folding box, is made from a hard cardboard plate 4' covered by a film plate 5'. Both plates 4', 5' have a length and width such that the length of the locking bar 2 and the widths of the side walls 21 are formed. A V-shaped groove 6' running in the longitudinal direction divides the hard cardboard plate 4' into two side walls 21. The side walls are held together by folding them together and applying adhesive 7' to the groove surfaces. In the area of their opposite open sides 26, recesses 23 are made which at least partially penetrate both side walls 21. The recesses and the recesses 13 are compatible with each other in such a way that a locking bar with its recess 23 can be hung in two opposite recesses 13.

In the folding boxes (see Fig. 3), stabilizing blocks 15 are attached to their corners. They are wide enough to reach from recess 13 to recess 13 and end with the open side 12.

In Fig. 3, two locking bars 2 are suspended in a folding box 1. Each locking bar 2 engages with its continuous recess 23 in the two adjacent recesses 13 and the tongue 14 of the folding box in between. The side walls rest against the recesses 13. Once the recesses 13 have completely taken up the recesses, the upper edges of the side walls 11, 21 are flush with one another in the area of the open side 12, 22. This means that each locking bar is suspended in a folding box 1 in the correct size and position.

Before the individual locking bars 2 are hung, the folding boxes 1 are suspended from a ceiling or the like of a room. For this purpose, a hanging element is located inside the folding box above the side 11 opposite the open side 12. With the help of this hanging element, the individual folding boxes are brought to the desired height relative to a floor surface. Because the individual folding boxes hang freely downwards, locking bars 2 can be easily hung on the folding box, which acts as a node - as shown in Fig. 4. A tensioned fabric insert can then be stretched between the individual folding boxes. This tensioned fabric insert can also be attached in the middle of the folding boxes to the fabric fixing recesses 27 of the stabilizing blocks 25.

The installation recesses allow all types of supply lines to be laid concealed in the grid construction. In addition, it is possible to hang lighting fixtures and other furnishings on the side walls 11, 21 of individual folding boxes 1 or grid beams 2.
