Problems solved by technology

A disadvantage of these wire networks is that they deform during storage and transport by rolling up, making laying and actual installation more difficult
In this connection, they create a further disadvantage in that due to their construction they cause greater deformation
[0003] In the case of welded grids, the disadvantage is that these are only manufactured in small areas, since they cannot be rolled and are also heavy

Embodiment Construction

[0019] Figures 1 and 2 show an element 1, which has been bent uniformly several times, extending on a longitudinal axis A, for a grid-like mat 10 shown in Figure 4, preferably with a flat cross-section from a metal strip bending. The longer cross-sectional side has a side length b, which is, for example, 10 to 15 mm. In Fig. 2, the thickness of the strip is designated e (for example it is 1 mm). For example, element 1 can use 1000 to 2200N / mm 2 Made of high tensile steel rated for tensile strength. The individual bends of the element 1 shown in the embodiment are substantially U-shaped, while the sides 1a (distance according to FIG. 2 ) connecting the two legs 1b, 1c of the prongs are slightly smaller than at the open end of the prongs. The distance a1 between 1b and 1c.

[0020] The length of the legs 1b, 1c is denoted h in FIG. 2 . Two openings 3 , 4 made in each foot 1 b , 1 c at a somewhat smaller distance d from each other are used for connecting pins or shafts 2 , p...

Abstract

Disclosed is a grid-shaped mat which is used especially for protecting floors or strengthening a floor cover. Said grid-shaped mat comprises a number of strip-shaped elements (1, 1'; 1'') which are bent several times, extend in a longitudinal direction (A), and form the grid structure of the mat (10). The lateral length (b) of the element (1, 1'; 1'') that is longer from a cross-sectional perspective runs perpendicular to the longitudinal direction of the mat. At least two adjacent elements (1, 1') are hingedly connected to each other with the aid of at least one pin (2) that extends in the longitudinal direction (A) of the elements, respectively. Such a mat is easy to produce while the floor cover that is applied to the mat coheres significantly better after drying and hardening than when a conventional wire grill is used.

Description

technical field [0001] The invention relates to a grid-like mat, in particular for soil retention or for the protection of ground cover, and also to the use of the inventive mat according to one of claims 1 to 10 . Background technique [0002] Mats of this type are known in the prior art in the form of a grid of flat wires, welded by wire or intersected as a grid of hexagonal wires. They are used, for example, to reinforce asphalt overlays. Such mats are delivered on roll or as panels to a location where they are laid out on the ground before the asphalt layer is applied. Once the asphalt layer has dried and hardened, they improve its cohesion. A disadvantage of these wire networks is that they deform during storage and transport by rolling up, making laying and actual installation more difficult. With regard to this connection, they create a further disadvantage in that they cause greater deformations due to their construction. [0003] In the case of welded grids, it ...
