Flattened building element

The invention relates to a plate-shaped component consisting essentially of plaster of paris, preferably plaster of paris for the formation of single-leaf walls, especially partition walls, of buildings,

There are also known as Vandbauplatten construction elements made of plaster of paris, for example in the DIN 18163 are described. These known components have the shape of a body delimited by rectangles pers each with flat surfaces, the abutment surfaces preferably generally with a groove or a tongue are provided in order to be able to connect two panels with a tongue and groove connection.

The known plate-shaped components consist of plaster of paris to which water is added during manufacture. In addition, certain chemicals can be added, which Lather the plaster of paris into forum plaster. The bulk density of the known plasterboard is 0.6 to 0.9 kg / dm *. To achieve a sufficient strength of the well-known platteaför = Migen components are given in the above-mentioned DIN 18 163 guidelines.

These known gypsum blocks have proven themselves well for partitions in buildings because they are relatively inexpensive to manufacture and after their installation result in smooth walls in dry construction, so that plastering in the usual sense is not necessary *

However, it has been shown that the known wall construction panels made of plaster of paris meet the high requirements with regard to sound insulation, as they are nowadays in particular, for example in hospitals, research institutes? ”Office buildings öte. but are also placed in residential buildings, not yet, correspond in a desirable way. Because with the known wall construction panels there is only an average sound reduction index of 32 dB or at most 35 dB to achieve.

The invention is based on the object of improving the known component of the type described at the outset while avoiding the above disadvantages in such a way that considerably better sound insulation is achieved while maintaining the other properties, as prescribed or recommended, for example, in DIN 18163, taking these on as cheap as possible Way should be made possible.

As a solution to this task, it is provided according to the invention that at least one protruding from the interior of the component

an abutment surface from inwardly extending recess is present, which is filled with a fine-grained filler material is filled out.

In a preferred embodiment, the invention provides that sand is used as filler material, preferably with a sand grain size of 0 to 3 mm is provided. Because this filling material is on the one hand relatively cheap and on the other hand meets the requirements set to a surprisingly high degree.

It is also preferably provided that several such recesses are present in a plate-shaped component are, the recesses expediently each extending to the opposite band of the component. According to one embodiment of the invention, the recesses have a round cross section. You can but of course in principle, also change cross-

In the case of several recesses, these are expediently arranged parallel to one another, the mutual spacing two adjacent recesses can each be essentially the same size.

It has been shown that a medium airborne sound insulation of 38 dB with a flattening thickness of 80 * mm and 40 dB A flattening thickness of 100 mm, that is to say a considerably high Vex'te, can be achieved if the external volume filled with sand is so large that there is an average bulk density of the component of 0.75 kg / dm *, with such Design otherwise the properties, in particular the required strength properties, are maintained, as required or recommended, for example, in DIN 18163.

Although the component according to the invention can of course be used with the most varied of thickness dimensions has been found to be particularly suitable for panel thicknesses between 6 and 12 cm, in particular 8 and 10 cm.

In order to achieve the preferred bulk density given above with such a structural element and the per se usual dimensions of a length of 666 mm and a height of 500 mm, and yet to maintain the other essential properties of full gypsum boards as desired , a board thickness of 10 cm, the recess diameter is 4 cm and the mutual distance between two recesses is 5 cm.

: The invention is based on an exemplary embodiment below

< line I-I in Figure 2; and

FIG. 2 shows a cross section through the component according to FIG. 1 in the direction of the section line II-II in FIG. 1.

The drawing shows a plate-shaped structural element 2 consisting essentially of porous gypsum 1 for forming single-shell partition walls of buildings.

A plurality of recesses 3 are provided in the interior of the component 2, each of which extends from the one abutment surface 4 of the component 2 to the opposite abutment surface 6. The recesses 3 each have a circular cross section and have a diameter d of 4 cm (3. Fig. 2). De? mutual distance t between

see two recesses 5 is 5 cm each. The length L of component 2 is 666 mm, while its height H is 500 mm and its thickness T is 100 mm.

The openings 3 of the component 2 are made of sand 7 with a grain size of 0 to 3 n ™, which is filled in after filling is shaken on a vibrating table and is therefore in a correspondingly dense pack. Instead of a filler material Another fine-grained filler material, such as meal, could also be used, however this would not lead to as inexpensive a design as this is sought.

Due to the dimensions given above, i.e. in particular due to the formation of the recesses arranged parallel to one another with a constant mutual spacing or their sand filling j results in an average Density of component 2 of 0.75 kg / dm * and this Density the astonishingly high sound reduction index of 40 dB

The particular advantage of the Bauelement® according to the invention is therefore in particular its extraordinarily high level Sound insulation, which while maintaining the other positive properties of known generic plasterboard, so in particular the strength, fire resistance, etc. is achieved, with the individual components in the The preferred dimensions given above have a weight of only about 25 kg and are therefore also very good are to be handled.

The spring attachments provided on the abutment surfaces 4 and 8 are denoted by 11, while the groove-shaped recesses are designated by 12 on the abutment surfaces 6 and 9.
