Grid-like insert for traffic areas, Floors, walls or the like.

The innovation relates to a grid-like insert made of flexible material, especially plastic, For traffic areas, floors, walls or the like., Consisting of at least two intersecting groups of profile strips with one open at the bottom to accommodate heating wires serving profile, especially U-profile.

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.

The innovation is characterized by tube-shaped, protruding downward from the intersection of the profile strips and / or in sight of the profile strips at least partially laterally outwardly protruding connection nozzles.

The connection pieces according to the innovation have the task of on the one hand to include the electrical connection lines, via which the power supply to the grid arranged heating wires takes place and on the other hand also serve to accommodate wire loops of the heating wires itself, which in view of the sometimes considerable expansions of the heating wires as a result of the action of heat or shortening is important at low temperatures. These expansions and shortenings of the heating wires then only have an effect affect the wire loops in the connection piece but not the position and internal tensions of the heating wires installed in the heating grid.

The innovation is based on the drawing through an exemplary embodiment explained in more detail, without being limited thereto.

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

Fig. 2 shows a plan view of a section of the grid element according to Fig. 1 with a laterally protruding Then do it.

FIG. 3 is a section along III-III of FIG. 3.

FIG. 4 is a section along IV-IY of FIG. 3.

Fig. 5 shows a crossing point of the grid element with a connecting piece protruding downwards.

Fig. 6 shows the connection piece according to FIG. 5 in the removed State.

The lattice-like insert to which the "subject of the fire" refers is expediently made composed of several grid elements. An execution example such a grid element is shown in Fig. Verans chauli cht.

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

es / profile strips on. In practice, however, it is cheaper to use larger grid elements with a larger number of profile strips, e.g. twelve per share. In the Heating wires are laid in the hollow spaces of the profile strips that are open at the bottom.

Tubular connection pieces 2, 3 are detachably arranged on the grid element, the connection piece 2 in Sighting one of the profile strips 1 runs and protrudes laterally over the hand of the grid element to the outside, while the connection piece 3 protrudes from a point of intersection of the profile strips 1 downwards.

The connection piece 2 has over part of its length a longitudinal slot and transverse slots for the Passage of the profile strips crossing the connecting piece 2 on (Fig. 2 Ms 4).

The connecting piece 3 has frontal notches 4, which are used to attach the connecting piece 3 to the underside of the profile strips 1 in the area of an intersection of the same (Fig. 5,6).

The connecting pieces 2, 3 are used to accommodate the electrical connection lines for the power supply the heating wires laid in the grid and / or to accommodate wire loops of the heating wires of the grid, these Wire loops are intended to remove any stretching or shortening of the heating wires laid in the grid to compensate for temperature fluctuations.

So that as a result of the wire loops mentioned, at least in the vicinity of a connection piece, a bit loose Heating wires lying in the inner cavities of the profile strips 1 are better guided, the profile strips have inwardly directed retaining lugs 5 for the heating wires on (Fig. 4).

Claims (4)

PA 831813 * 23.1 * 63 - 5 - Protection claims: 1. Grid-like insert made of flexible material, especially plastic, for traffic areas, floors, walls, Or the like., "Consists of at least two intersecting Flocks of profile strips with a downwardly open profile serving to accommodate heating wires, in particular U-profile, characterized by tubular, from the intersection of the profile strips downwards Connection stub protruding and / or in the seal of the profile strips, at least partially laterally outwardly protruding. 2. Honeycomb-like grid according to claim 1, characterized in that the cross sections of the profile strips downwardly protruding connection piece on the face side notches for attaching the connection piece to the Have underside of the profile strips in the area of a crossing point. 3. Honeycomb-like grid according to claim 1, characterized in that the laterally in the direction of the profile strips outwardly protruding connection piece extending over at least part of its length Longitudinal seat and transverse slots for the inlet or passage of the profile strips crossing the connecting pieces of the grid. 4. honeycomb-like lattice according to one of claims 1 Ms 3> characterized in that the profile strips have inwardly directed retaining lugs for the heating wires.
