Abstract

The plasterboard (1) with preferably two outer layers cardboard or paper layers (12, 13) bounding a plaster layer (14) is provided with a groove (3), as well as with connecting and reinforcing elements (3, 5) allowing the sections (10, 11) of the plasterboard to be folded on one another. An Independent claim is also included for a method for producing the proposed plasterboard.

Description

The invention relates to a plate from a plasterboard and a method for producing a plate element made of plasterboard.

For Interior fittings in buildings in drywall construction, it is known to have panels made of individual, mostly rectangular To install plasterboard on site. Gypsum plasterboard exist from two outer layers made of cardboard or a thicker paper and one of the two outer layers connecting plaster layer. During assembly, the plasterboard assembled at a distance from one another and fastened to support structures, mostly screwed. The between the individual plates on the abutting surfaces or Intermediate joints formed on the narrow sides are filled with a joint filler locked.

This is done in a known embodiment the intermediate joints after installing the panels and fastening the support structure with Filled plaster and then sanded if necessary. You get therefore practically invisible due to the same materials for panels and joints Joint or a de facto seamless appearance of the ceiling. Also done the closing or fill the intermediate joints after the assembly of the panel assembly and at assembly does not have to take the joint material into account.

In an alternative known embodiment will be placed on the narrow side of one of the two butt Panels, usually on the already assembled panel, an adhesive is applied and pressed the other plate with the narrow side against the adhesive and at the same time on the support structure attached. This well-known method, in which the two plates glued together is efficient and allows a stable Grouting the intermediate joints. However, when installing the Plates a special accuracy and the right speed be adhered to so that even before the installation of the other Plate applied glue does not dry too soon and the plates come to rest in the correct position.

In both known methods of closing the intermediate joints must have a liquid or viscous joint material (Plaster or glue) are processed, the soiled by it surfaces is difficult to remove, and so it always has to be in drywall still work with a wet material.

Around steps or angular wall or to realize ceiling sections with plasterboard, two Plasterboard is mitred at an angle to each other become.

Out DE 198 09 606 A1 is now known for this purpose angled, cardboard-clad gypsum board element, which is made from a gypsum board by creating a V-shaped groove that cuts through the gypsum board, but not the bottom cardboard layer, applying a double-sided adhesive tape to the groove and folding the two plate parts separated by the groove is produced by gluing the two adhesive sides of the adhesive tape.

In this known plasterboard element is not a liquid Joint material required more. No plattform will be made produced separate plasterboard, but the two angle plate parts hang over the bottom cardboard layer always together, that as a hinge when folded of the two plate areas separated by the V-groove acts and so also causes an automatic adjustment when folding.

A certain disadvantage with this known angle plate element according to DE 198 09 606 A1 consists in the fact that the hinge formed by the outer layer of cardboard is quite weak and can be damaged or torn apart if it is folded back and forth several times or due to external influences.

The object of the invention is now based, at least the problems mentioned in the prior art to partially avoid or at least alleviate.

This object is achieved according to the invention solved by a plate made of plasterboard with the features of the claim 1 and by a method having the features of claim 20.

• e) two areas of the plate separated by the groove are folded or folded towards one another around the groove base and / or the reinforcing element and are connected to one another by the connecting element.

The invention is based on the consideration the connection between the two plate areas separated by the groove to be reinforced at the bottom of the groove by at least one reinforcing element and thus also the hinge for to make the folding movement of the two plate parts more stable. This makes it possible in particular the outer location (s) from thinner or lighter paper or cardboard.

Advantageous configurations and Developments of the plate or the method according to the invention result from the claims dependent on claim 1 and claim 20, respectively.

The reinforcing element is preferably as Hose, rod, strip, ribbon or thread formed.

There is also the reinforcing element generally from a more tearproof one Material as the cardboard or paper of the outer layer (s). This will make the reinforcement of the groove base and the folding hinge increased.

In particular, there is the reinforcing element even at least approximately as easy as the plaster layer separable material, so with one Separate the plate along the groove cross section also the reinforcing element can be easily cut with.

As the preferred material for the reinforcing element a plastic or metal is selected, for example one as well easy to separate like the plaster material. But it can also a softer metal can be provided, for example aluminum or Copper.

The groove base and / or the reinforcing element and / or the connecting element is or is preferably a hinge or some kind of hinge for the folding movement of the two areas of the plate is formed. The regions of the plate separated by the groove are therefore preferred rotating around a substantially through the groove bottom, the reinforcing element and / or the axis of rotation extending on one another too foldable or folded.

At essentially parallel to each other directed groove side walls or joint side walls the groove has largely disappeared when the plate is folded and / or at least partially, preferably completely, by filled out the connecting element. The plate or the two plate parts now form or form one angular Element with the two plate areas previously separated by the groove as legs or angle flanges. This angle plate element can be especially for corresponding angle or step areas in ceilings and walls or wall connections and cornices and pre-wall systems can be used in drywall.

Generally the outer layer forms or the second of the two outer layers at least partially the bottom of the groove.

Additionally or alternatively but also the connecting element or, as already stated, the reinforcing element at least partially form the bottom of the groove. This is especially in Combination with an embodiment the case in which the groove in the plate is continuous or as open Slit is formed, so there is no longer a groove bottom of the plate and the two plate areas as individual plates from each other are separated. The formerly a slab now forms a slab assembly from two individual plate parts. The bottom of the groove is now replaced by the reinforcing element and / or the connecting element, which or the two plate regions hold together and / or form the hinge for the folding movement or forms.

The reinforcing element can also be parallel to the actual groove base outside of the bottom of the groove.

The at least one connecting element is attached to at least one or both of the groove side walls, especially glued. In a special embodiment is a coherent connecting element arranged on both groove side walls.

The reinforcing element and the connecting element are preferably connected or connectable to one another. In particular, the reinforcing element is integrated in the connecting element bears, in particular at least partially enclosed by this, for example overmoulded or encapsulated.

The reinforcing element can also be used the connecting element in one piece or be formed as a molded part, in particular as a material reinforcement or Bead in the connecting element.

The reinforcing element can also the plate, in particular the groove side walls and / or an outer surface of the Plate.

The groove side walls can initially have a wide range freely selectable Have shape, for example a convex or concave shape or a hybrid of them. In an advantageous embodiment are the two groove side walls, however essentially flat. This allows a simple flat concern of the connecting element and the groove side walls together in the folded Condition of the plate.

The two prefer to meet groove sidewalls essentially on or in the groove base in a cutting line. This Cutting line runs then in a gypsum board preferably through the not of the groove separated outer layer. With flat groove side walls the groove generally has a V-shaped cross section with a essentially linear Groove on.

However, it is also possible that the groove side walls only outside cut the plate or groove base in their geometric extensions or meet each other and / or at the bottom of the groove still spaced apart are. The groove then has in particular a trapezoidal cross section with a flat or flat Groove base. This embodiment represents for the reinforcing element An additional Space when merging of the plate areas or plates available. It also creates folded angle plate element through a rounded edge that is outward suppressive Reinforcing element. For example, this has the advantage that the color on the rounded Edge adheres better. This also improves stability.

Generally, they close two groove side walls in parallel, separated by the groove Areas of the plate a predetermined angle to each other, the is less than 180 °, especially between 60 ° and 120 ° and preferably at least approximately Is 90 °. About this Opening angle between the two groove side walls is the later final angular position of the two plate areas with the folding movement and connection completed Are defined. In general, the two angles are approximately the same because the connection at approximately parallel groove side walls and the plate areas with the groove side walls to each other by this opening angle have to be folded. For example, with flat groove side walls and an angle between the groove side walls of 90 ° also a right angle (90 °) between the two plate areas when folded realized.

The connecting element comprises in an embodiment at least one Velcro, which in the Nut is attached, in particular is glued. In particular is then at least one first Velcro element on one of the two groove side walls with Velcro and on the opposite Groove side wall at least one corresponding second Velcro element with Velcro eyelets provided, the Velcro hooks with the Velcro loops when folded towards each other Interlock areas of the plate. In particular is as a Velcro at least one Velcro tape known per se is provided.

In an alternative or additional Configuration has at least one connecting element at least a double-sided adhesive tape, which with an adhesive Side is glued to the plate, especially the groove side walls or will or can be stuck on. The other adhesive side of the tape can be covered with a peelable protective layer, the front the folding of the two plate areas is subtracted.

Alternatively, it is also possible to use the other adhesive side of the tape during a predetermined, sufficient time to assemble the panels (or: processing time) to keep non-sticky and only then the adhesive To make a connection, for example by using two different components of a two-component adhesive or one under the air slowly hardening Glue or a substance that only sets when it comes into contact with the plaster or a cold vulcanization.

For stabilization and better adhesion the connecting element on the plate, the connecting element also be continued from the groove and on the adjacent outer surface of the Plate in addition be attached.

The plate and the one made from it Plate element are preferably used as a ceiling or wall construction used in the interior of buildings.

The invention is explained below of embodiments explained further. Reference is made to the drawing in which

1 a plasterboard with a cross-sectionally V-shaped groove and a connecting element and a reinforcing element on the groove base,

2 a plasterboard with a trapezoidal groove in cross section and a connecting element with a molded reinforcing bead and

3 one from the plasterboard according to 2 angular plate element produced by folding are each shown schematically. Corresponding parts and sizes are in the 1 to 3 provided with the same reference numerals.

The plate 1 according to 1 to 3 has two outer layers 12 and 13 made of paper or cardboard and an inner layer of plaster as an intermediate layer 14 between the two outer layers 12 and 13 on. The outer locations 12 and 13 and the liner 14 are in the 1 and 2 parallel to each other and in all 1 to 3 flat or flat.

Through the first outside location 12 and the liner 14 is in the embodiment according to 1 one to the second outer layer 13 reaching V-shaped groove 4 generated, for example by cutting or milling. The groove 4 has two flat groove side walls 40 and 41 on the bottom of the groove 42 meet in a line and enclose an angle α, which in the example shown is 90 °. The groove 4 So opens to the open side or the distance of the groove side walls 40 and 41 takes towards the bottom of the groove 42 away to.

In or on the outside location 13 is therefore at the bottom of the groove 42 a hinge 43 formed around which the two through the groove 4 separate areas 10 and 11 the plate 1 are mutually pivotable or foldable.

In the groove 4 is now a connecting element 3 arranged that on the in 1 left groove side wall 40 a first sub-element 30 , for example a Velcro tape with Velcro loops or an adhesive tape, and on the in 1 right groove side wall 41 a second sub-element 31 , for example a second Velcro tape with Velcro or a second adhesive tape. The two sub-elements 30 and 31 are on the groove side walls 40 and 41 attached, especially glued. The connecting element 3 connects the two groove side walls 40 and 41 with each other when the two areas 10 and 11 the plate 1 around the hinge 43 to be folded towards each other until the sub-elements 30 and 31 to connect.

At the bottom of the groove 42 is in the groove 4 according to 1 is now to reinforce the hinge 43 and avoid tearing the outer layer 13 a rod-shaped reinforcing element 5 arranged that with the groove side walls 40 and 41 and with the two sub-elements 30 and 31 of the connecting element 3 is connected, for example glued again.

The reinforcing element 5 consists of 1 in particular from a plastic or metal, for example a material that is as easy to separate as the plaster material. However, a softer metal can also be provided, for example aluminum or copper.

Also protrudes in 1 the connecting element 3 also from the groove 4 out and in the sequel is not just on the two groove side walls 40 and 41 but also on both sides with protrusions 32 on the outside location 12 attached, in particular glued, for additional stabilization and to achieve a larger adhesive surface for the connecting element 3 ,

In the embodiment according to 2 is the bottom of the groove 42 is flat and the two groove side walls 40 and 41 are at the bottom of the groove 42 still spaced apart and only meet in their geometric extension outside the plate 1 ,

The two sub-elements 30 and 31 hang according to 2 at the bottom of the groove 42 together, the connecting element 3 is thus continuous or coherent, for example by using a continuous Velcro or adhesive tape.

In the area of the groove base 42 has the connecting element 3 now a thickening or a reinforcing bead 50 as an integrated reinforcement element to reinforce the hinge 43 on. The connecting element 3 with the reinforcing element 50 can be produced as a molded part, for example as an injection molded part made of PVC.

The reinforcing element 5 or 50 or the connecting element 3 is generally used when mounting on the ends of the groove 4 separated.

3 now shows the plate 1 according to 2 after swiveling or folding the two areas 10 and 11 towards each other by the angle α and then rotating the entire plate 1 by 90 °. The two groove side walls 40 and 41 and the two sub-elements on it 30 and 31 of the connecting element 3 are now parallel to each other and the connection, in particular the Velcro connection or adhesive connection, between the sub-elements 30 and 31 is made.

In in 3 shown folded state of the plate 1 is the groove 4 practically no longer visible and completely through the connecting element 3 with the reinforcing element 50 filled. The plate 1 now forms an angular plate element with the two previously according to 2 through the groove 4 separate areas 10 and 11 as legs or angle flanges, which enclose the angle α with one another, that is, in the example shown, are directed orthogonally to one another.
