Grid-shaped mat

Grid-shaped mat description/claims

The invention relates to a latticed mat, especially for soil conservation or to protect a ground covering, and also the use of the inventive mat according to one of claims 1 to 10.

Mats of this type in the form of flat wire lattices, made of wires welded together or interwoven into a hexagonal wire mesh, are known in the art. They are used, for example, to reinforce asphalted ground coverings. Such mats are delivered to the site in rolls or as panels, where they are spread out on the ground before application of the layer of asphalt. Once the asphalt layer has dried and hardened, they improve its cohesion. One disadvantage of these wire lattices is that they are deformed by being rolled up during storage and transport, rendering laying and actual installation more difficult. A further disadvantage to which they are subject in this connection is greater deformation due to their structure.

In the case of welded lattices, it is disadvantageous that these can only be produced as small areas, since they cannot be rolled and are also heavy. Due to the approximately two-dimensional design of these lattices, only a very limited wedging or bonding between them and the material surrounding them occurs.

The present invention is based on the problem of creating a latticed mat of the first-mentioned type, which enables simple handling with respect to storage and installation, and with which the reinforcement of a ground covering, or the protection of the ground, of the slope or similar is improved, with which the thicknesses of the layer is reduced or an increase of the lifetime of same is effected.

This problem is solved according to the invention by a latticed mat with the features of claim 1.

Further preferred embodiments of the inventive latticed mat and their use form the subject matter of the subclaims.

The inventive latticed mat is simple and economical to manufacture. It can be used for a wide variety of purposes. Its use is especially advantageous in the reinforcement (armouring) of asphalted ground coverings. The mat has a number of strap-shaped elements, curved in several places and extending longitudinally, which form the lattice structure of the mat. The depth of the interstices corresponds to the side of these elements which is longer, seen in cross-section, which can for example be 10 to 15 mm.

The layer of asphalt applied to the inventive mat coheres substantially better after drying out and hardening than when an ordinary wire lattice is used.

This means that the asphalt layer consolidated according to the invention better withstands both stresses and weathering (frost, high temperatures etc.), i.e. in particular, cracking and deformations of the ground covering, which lead to expensive maintenance works, are largely prevented. Vehicles may also be driven over the inventive mat before or during asphalting, without it being damaged or displaced as a result.

A further advantage of the inventive mat lies in the fact that it can easily be rolled up into a roll or folded like a concertina and spread out again, without the risk of the mat becoming deformed or entangled in itself by being rolled up and thereafter being difficult to spread out.

The invention will next be explained in more detail with the aid of the drawings, which show:
