Grid-like use for "traffic areas, floors, walls or the like.

The innovation relates to a grid-like insert made of flexible material, especially plastic, consisting of at least two intersecting groups of profile strips with one open at the bottom, preferably Profile, especially U-profile, used to hold heating wires.

Such grid-like inserts are on any surface, e.g. made of concrete, asphalt or the like. upset and the gaps in the grid are filled with suitable building materials.

The task of these grid-like inserts is, among other things, to create a system of channels for reception of heating wires, which enables electrical heating of the surface covering. Furthermore it is

one task of the grid-like inserts is to create a surface covering that is applied to a substrate is arrested with this shovel safe.

The inherently rigid building material cells in the interstices are compressible due to the special design of the profile strips of the lattice-like insert Partitions, namely by the profile strips of the grid, separated, whereby the surface covering in its The whole is given a flexibility that allows adaptation to unevenness of the ground and Prevents cracking and loosening of the surface covering from its subsurface.

According to the innovation, there is an expedient embodiment of the lattice-like inserts described in that the honeycomb-like grid consists of several rectangular or is composed of square grid elements, with a simple one for connecting the individual grid elements Plug connection, preferably in the manner of a push button connection, is provided.

This makes it possible, from individual smaller grid elements to one of the given dimensions of the covering surface corresponding grid-like insert quickly and reliably put together.

The innovation is based on the drawing by an

management example explained in more detail, without being limited to it.

Fig. 1 shows diagrammatically a square grid element a grid-like insert according to the innovation.

"ig. 2! Ü is a _rough f _s j_cht on the grating eggs ent according to Fig. 1, wherein also a part is shown of an adjacent grating element.

Fig. 3 is a section along the line IH-III of Fig. ■ 2 and

The grid element according to the embodiment consists of two intersecting sets of profile strips 1 with a U-profile open at the bottom. From representational For reasons, the grid element has only five per group Profile strips on. In practice, however, it is more beneficial to use larger grid elements with a larger number of profile strips, e.g. twelve per coulter to be used.

In the area of the crossing points of the profile strips 1 protrude from the lower hand of the profile strips parallel to a large area "Projections 2 lying to the grating surface" like a rosette into the interstices between the grating. These protrusions 2 serve to ensure that the grid after it has been laid on the base and the grid spaces with a suitable Building material have been filled in, can no longer climb. The building material filled into the gaps between the lattice

rather, it connects with the underground, namely a burden on the projections 2 and thus prevents the grille from lifting off the ground.

In contrast, the lattice-like insert or its profile strips should be able to deform deformations in the lattice plane to record. Such deformations are caused by movements of the building material cells in the spaces between the grids, caused by movements of the subsurface and by loads on the surface. In her lower Area, the profile strips of the grid are easily deformable due to the freely ending side walls there. However, in order to ensure the necessary deformability in the upper area of the profile strips, the upper Cover strips of the profile strips between each two crossing points Buckles 3 formed, which act like a fold.

The "connection of the grid elements to one another takes place in such a way that the edge profile strips of adjacent grid elements overlap. Each of them covering edge profile strips have downward facing jibs 4-, which in openings 5 of the covered End profile strips engage, creating a simple

Plug connection between the individual grid elements is achieved .. The cams 4- point expediently a circular cross-section, while the openings are elongated to avoid any compensating movements

Claims (3)

PA 831812 * 23.12.6 to allow between the individual grid elements. The diameter of the head of the cams 4- is advantageously slightly larger than the (smaller) width of the openings 5, which results in a type of connection that is similar to a push-button connection. Protection claims: 1. Grid-like insert made of flexible material, in particular plastic, consisting of at least two crossing flocks of profile strips with a downwardly open, preferably for receiving heating wires serving profile, in particular U-profile, characterized in that the honeycomb-like grid consists of several Rectangular or square lattice elements are composed, for the "connection of each." Grid elements a simple plug-in connection, preferably in the manner of a push-button connection, is provided is. 2. Lattice-like insert according to claim 1, characterized in that the on the edge profile strips of the lattice elements trained connecting organs consist of crouching and openings. 3. Lattice-like insert according to claim 2, characterized in that the cams have a circular cross-section have, but the openings are elongated. 4, lattice-like insert according to claim 2 or 3 »thereby characterized in that the diameter of the head of the cam is slightly larger than the diameter or the width of the openings. 181263
