Abstract

The system has a V-shaped cross section. Gypsum perforated tiles (21, 21') are provided with visible surfaces (24, 24'), rear surfaces (23, 23') and edge surfaces (25, 25'), respectively, and are shifted to a distance opposite to a wall or cover surface by sub-construction. Each rear surface is assigned to the wall or cover surface, and each visual surface is assigned to an inner side of a space. The system is designed in such a manner that a distance (c) of the adjacent tiles in a plane of the visual surface is larger than a distance (b) of the adjacent tiles in a plane of the rear surface.

Description

The invention relates to a joint system for perforated plates. Perforated plates, in particular plaster-perforated plates, have a visible surface, a back surface and four edge surfaces. They are usually laid in a composite against a wall or ceiling surface. Usually, a substructure is used to lay the perforated plates at a distance from the wall or ceiling surface. The perforated plates are usually used to improve the acoustics in rooms, to which the back surface usually still has a specially trained layer to dampen the sound waves. The layer on the back side can also be designed so that an adhesion to the substructure is possible. The transition region from one to another adjacent perforated plate after its attachment to the wall or ceiling or to the substructure provided for this purpose forms a joint system. So the joint system includes the edge surfaces adjacent laid perforated plates.

Conventionally, the edge surfaces of two adjacently laid apertured plates are aligned parallel with respect to each of two imaginary coordinate axes defining the plane of the edge surface of a perforated plate. The vertical distance between the edge surfaces is about 2 mm, if a so-called gluing technique is used for the connection along the joint of the adjacent laid perforated plates. However, if a spatula technique is used to connect along the joint of the adjacent laid perforated plates, then the vertical distance between the edge surfaces is about 4 mm.

It was recognized that both in the adhesive technique and in the spatula technique no complete or uniform filling of the joint is possible, which also at least partially lost the favoring acoustic properties attributed to the perforated plate or its composite. Furthermore, usually adhesive material or putty material is present in an uneven manner over the plane of the visible surface of the perforated plate, which requires a difficult post-processing.

The object of the invention is therefore to make a joint system described above more suitable.

The solution to this problem is that the joint system is formed so that substantially a distance between adjacent perforated plates in the plane of the visible surface of the perforated plates is substantially greater than substantially a distance of adjacent perforated plates in the plane of the back surface of adjacent perforated plates.

Such a joint system according to the invention allows, in particular when using the spatula technique, a uniform introduction of the filler into the space which exists between the edge surfaces of the adjacent perforated plates. The construction worker can, so to speak positively motivated follow, as the putty introduced by him in the space between the edge surfaces actually remains in the desired manner. It may also be desired that a small projection of the filler is formed opposite to the surface of the visible side of the perforated plate, so that after solidification of the filler, z. B by dehydration and a possible loss, the level the level of the visible surface of the perforated plate is by no means undershot and smaller protrusions of the solidified filler can be easily abraded, so that the optical requirements for the visible side of the perforated plate or the relevant perforated plate composite can be fully met. Due to the complete filling of the space between the edge surfaces of adjacent laid perforated plates with solidified filling material, the properties intended for the perforated plate composite, such as, in particular, the desired acoustics, come into their own.

Although, of course, the distance to a mean distance between adjacent perforated plates in the plane of the visible surfaces of the perforated plates may vary, for. Example, if a particular geometry of the surfaces of the edge surfaces should be selected, but a preferred uniform spacing of adjacent perforated plates in the plane of the visible surfaces of the perforated plates along the entire length or width of the respective adjacent perforated plate is preferred because this is associated with manufacturing advantages for the respective perforated plate ,

It has been found that the advantages of the invention are particularly favorable when the distance between adjacent perforated plates in the plane of the visible surfaces of the perforated plates in the range of 3.6 mm to 4.5 mm at a thickness of the respective perforated plate of about 12.5 mm is located. Further, it has been found to be advantageous if the distance between adjacent perforated plates in the plane of the back surfaces of the perforated plates is about 0.2 mm at, as already mentioned strength of the respective perforated plate of about 12.5 mm.

The surfaces of the edges of the perforated plates can be increased by various measures, such as grooves, bulges to achieve higher adhesion forces for receiving the adhesive or filler, which is within the scope of the invention, but it is preferred, the surface of an edge of a To execute the respective perforated plate level, resulting in a simplified production of the joint system according to the invention belonging perforated plate. In such a case, the cross section of the joint system according to the invention is also fairly exactly V-shaped. Of the V-shape slightly or slightly larger extent deviating cross-sectional shapes, however, also belong to the invention.

Furthermore, it proves to be advantageous if the predetermined distance of the adjacent perforated plates in the plane of the back surfaces of the perforated plates can be ensured by integrated into the perforated plate spacers, since then the assembly of the perforated plates, for. B. can be done with respect to the substructure without the aid of a measuring tool. The spacer elements are then arranged offset with respect to opposite longitudinal sides or broad sides of a perforated plate so that an unwanted addition of the predetermined distance can be excluded or only one longitudinal side or only one width side of a perforated plate is equipped with such spacers. If the integrated spacer elements are provided on all edges of the spacer elements, edge protection can also be achieved hereby.

The FIGS. 1a to 1c are aligned with the state of the art, as it exists in the spatula technique. Perforated plates 1 and 1 'are laid in a composite. They each have a back surface 3 or 3 'a visible surface 4 or 4' and edge surfaces 5 and 5 'on. In the transition from a perforated plate 1 to an adjacent perforated plate 1 '- both relative to a longitudinal side and with respect to a broadside - there is a distance a1, which is the same in the conventional spatula technique, ie the distance a1 is in the plane of the Visible surface 4, 4 'with respect to the region of the plane of the back surface 3, 3' completely the same. This distance is usually about 4 mm. In a joint region 2, which has the distance a1 between the edge surfaces 5 and 5 ', the filler is pressed by means of a suitable tool, such as spatula. It was recognized that usually no uniform filling of the joint 2 with the filler is possible.

The FIGS. 2a to 2c are aligned with the state of the art, as it exists in the adhesive technology. Corresponding reference numerals are increased by the amount 10 compared to the spatula technique. Again, the corresponding distance a11 in the region of the plane of the visible surface 14, 14 'with respect to the region of the plane of the back surface 13, 13' completely the same. This distance a11 is usually about 2 mm. It is observed that the paste-like adhesive to be introduced into the joint area 12 is not able to distribute itself uniformly in the joint area.

The FIGS. 3a to 3c give the joint system of the invention again. Perforated plates 21 and 21 'are laid in a composite. They each have a back surface 23 or 23 'a visible surface 24 or 24' and edge surfaces 25 and 25 'on. In the transition from a perforated plate 21 to an adjacent perforated plate 21 '- both With respect to a longitudinal side as well as with respect to a broadside - are now distances b and c before, which are different. The distance c in the region of the plane of the visible surface 4, 4 'is considerably greater than the distance b in the region of the plane of the back surface 3, 3'. This distance c, which was found out, should be best in the range of 3, 6 to 4.5 mm at a thickness h of the respective perforated plate of 12.5 mm. The distance b should best have a dimension of about 0.2 mm at a thickness h of the respective perforated plate of 12.5 mm. The edge surfaces 25 and 25 'are usually performed perfectly flat. However, the surfaces of the edges of the perforated plates can also be increased by various measures, such as grooves, bulges tend to achieve higher adhesion forces for receiving the adhesive or filler. If the surfaces of the edges are made completely flat, a characteristic V-shaped structure of the joint system is produced in cross-section. Although the distance b provided with 0.2 mm is already small with respect to conventional dimensions of a perforated plate and in the assembly of the plates, for example, on a substructure, hard to miss, it may prove advantageous, this distance through in the perforated plate in Ensure area of the rear panel integrated spacers.

The adjacent laid perforated plates, in particular gypsum perforated plates, form in the embodiment according to the invention a joint system with the characteristic V-shaped cross-section.

A putty with recommended by the manufacturer of the perforated plate or plasterboard composition is pressed by means of a suitable tool, such as spatula in the defined by the edge surfaces 25 - 25 'joint system. In this case, the construction worker can follow, so to speak positively motivated, how the filler introduced by him in the space between the edge surfaces 25 - 25 'actually remains in the desired manner. It can then also be provided that a small projection of the filler is formed opposite to the surface of the visible side of the perforated plate, so that after solidification of the filler, z. B. by dehydration and a possible shrinkage, the level of the plane of the visible surface of the perforated plate is not fallen below and smaller protrusions of the solidified filler can be easily sanded. The visual requirements for the visible sides 24 - 24 'of the perforated plate including the machined area in the region of the joint system according to the invention in the entire relevant perforated plate composite can then be fully met. As far as the perforated plates are used for the achievement of a particular room acoustics, the full filling of the space between the edge surfaces adjacent laid perforated plates with solidified filling material for the individual perforated plate present properties even in the perforated plate composite to full advantage.
