Stable flooring membrane.

The innovation relates to a stable flooring sheet with a compressible underlayer, which is made up of a large number of threads crossing one another and welded to one another at the crossing points with a diameter of 0.4 to 2.5 mm of existing mat web is formed, and a moisture-impermeable top layer, wherein of the two sides of the lower layer, at least the upper side facing the upper layer has a waffle-like structure is.

Such a stable floor covering sheet is known from German utility model no. 77 01 427. The compressible lower layer has a particularly high proportion of voids and such an open and large-pored structure, that on the one hand no moisture, e.g. in the form of capillary moisture, can pull up in it, on the other hand - For example, after damage to the top layer, moisture that has penetrated from above as a result of good ventilation

The structure is quickly removed. The moisture-proof The layer can be a soft PVC layer a few millimeters thick, in which the lower layer, for example, a 10 to 40 mm thick mat sheet, about 1 to 5 mm deep is embedded. The usable area, i.e. the upper side, the upper layer, can be profiled to increase the slip resistance or by applying a textile fabric, for example a fleece made of synthetic threads or fibers, has a better grip and made softer. The threads of the mat web forming the lower layer are preferably made of synthetic fibers Polymers, in particular made of polycaprolactam, however, are also the other common thread-forming polymers suitable.

This well-known .Stallbodenbelagsbahn has due to the the following application-related advantages have been tried and tested in practice:

- Wear resistance and slip resistance are enhanced by the usable surface (e.g. fleece, knitted fabric, conventional Carpeting) secured; Reinforcement inserts are possible.

- Thermal insulation and softness are brought about by the special compressible underlayer. The one in the Mattenbahn The air space located there ensures good insulation, which determines the deformation properties of the mat sheet the softness.

- As a result of the moisture impermeability of the top layer is a good cleaning option (hosing down

ensured with water), without penetrating moisture into the interior of the underlayer, and thus reduces the thermal insulation of this layer.

The well-known stable flooring sheet is usually delivered as roll goods, the roll width being the depth of the Stable boxes and cut to size on site. The convenience of sending the mat material on a roll, prevents the backsheet from being made as thick as it is for optimizing the compressibility properties would actually be desirable; because the thicker this layer, the stiffer and the stiffer the barn flooring it is worse to roll up.

Furthermore, it has proven to be advantageous if the edge areas of the stable flooring membrane (i.e. the circumferential Cut edges) are made impervious to moisture. This could be achieved with the known mat by that the cut can be made on all edges by at least a sheet thickness greater than normal and in the edge areas the lower layer removed so that the upper layer protrudes on all sides over the edge of the lower layer. To After laying the stable flooring membrane, the top layer could then be folded down and glued. Such an approach would be extremely complicated because the lower layer is partly embedded in the upper layer and the coarse-denominated ones Threads are very difficult to cut.

The innovation is based on the task, the possibility to open a thicker stable flooring membrane without having to hit the

Advantage of having to do without delivery by roll. In addition, the innovation should be a simple way to Create edge sealing by overlapping the top layer on all sides.

In solving this problem, the basic idea is to separate the lower and upper classes from one another manufacture, deliver by roll and cut to size, whereby the dimensions of the top layer are the same much larger than that of the lower layer can be chosen so that an overlap of the upper layer is possible on all sides. the The underside of the top layer has recesses that correspond to the elevations of the waffle-like structured top of the Corresponding to the lower layer in terms of spatial arrangement and shape. After the top and bottom layers have been put together and folding down the overlapping edges of the top layer creates a technical-functional unit on all sides Closed barn flooring that can be glued to the barn floor or mechanically attached to it.

The generic stable floor covering sheet is accordingly characterized according to the innovation in that the top layer has recesses on its underside facing the lower layer which, with regard to their spatial distribution and shaping the spatial distribution and shaping of the elevations of the wafer-like structured top are adapted to the underlayer, and that it is drawn down beyond the edges of the underlayer in such a way that that their underside lies in the protruding edge area in the plane of the underside of the lower layer.

"Structured like a weapon" is understood to mean surfaces which more or less regularly distributed elevations, for example in the form of domes, cones, truncated cones, Have pyramids or truncated pyramids. In the case of the lower layer used according to the invention, at least that of the upper layer should facing top be structured in such a way. The underside of the lower layer, preferably recesses (thread-free areas) corresponding to the elevations on the upper side. It is possible the bottom to stabilize the lower layer with a smooth sole made of a thread fleece, as described in the DE-OS 27 20 403 is known in principle.

The underside of the top layer has recesses which, in terms of spatial arrangement and shape, correspond to the elevations are adapted to the waffle-like structured top of the lower layer. This means once that everyone's elevation the lower layer is assigned a recess of the upper layer (same number per unit area and the same spatial distribution in the area of the recesses as in the case of the elevations), and on the other hand, that the shape of the recesses the upper layer is chosen so that the elevations of the lower layer can easily "snap into place". For frustoconical or dome-shaped elevations are, for example, recesses with a circular cross-section, recesses are used for truncated pyramidal elevations with a square cross-section preferred. Cross-sectional and depth dimensions of the recesses should be chosen as possible be that the surface lines of the recesses can rest on the surface of the elevations.

In order not to adversely affect the stability of the top layer, the depth of the recesses should preferably be less than 30%, preferably only 25 to 5% of the thickness of the Correspond to the upper class.

On the one hand to obtain a good form-fitting connection between the top and bottom layers, on the other hand To keep the insulating air space of the lower layer as large as possible, the depth of the recesses should preferably between 10 and 30% of the height of the surveys.

Depending on the type of barn (e.g. lying area) and the livestock to be housed in it (e.g. cattle), the form-fitting one is sufficient Connection of the upper layer with the lower layer via the recesses and elevations, or it is expedient to that the top layer with the bottom layer in the area of the recesses and elevations by gluing or the like. fixed connected is. It can be sufficient, this bonding or the like. to be carried out only in isolated places.

The innovation is explained with reference to the accompanying drawing, which (for a better understanding not to scale) a represents ready-to-lay stable floor mat, which consists of a lower layer 1 and an upper layer 2, the Top 1.1 of the lower layer 1 hump-shaped elevations 1.2, which engage in recesses 2.2 on the underside of the top layer 2. The upper layer 2 extends over the edges 1.3 of the lower layer 1 addition and is drawn down such that its underside 2.1 in the plane of the The bottom 1.4 of the lower layer 1 is located.

The top layer 2 can for example consist of PVC and be provided with a fabric reinforcement 2.3. The lower class 1 can be provided with a smooth sole made of a thread fleece or the like on its underside 1.4.
