Description

The invention relates to a street banquet board according to the preamble of claim 1.

The street banquet is a strip adjacent to a lane of a road. Unpaved street banquettes often break out at the side, which also damages the edge of the road. As a result, repairs of the roadside and the road banquet are often necessary, such repairs increase the maintenance of the infrastructure and cause traffic jams.

To additionally secure the street banquet, street banquet boards are known, which are placed next to the roadway edge on the street banquet in order to additionally support the roadway edge and to protect the road banquet.

A disadvantage of such street banquet boards is that they have to support the roadside and not be displaced by approaching vehicles, a large mass, whereby the installation is much more difficult and the use of cranes and the like is needed. Furthermore, in the curved area, gaps are formed between two adjacent street banquet panels, whereby the restraint capacity of the street banquet panels is reduced and these can be moved more easily.

The object of the invention is therefore to provide a street banquet board of the type mentioned above, with which the mentioned disadvantages can be avoided, with which a good support of the roadway edge in curves is possible and which is easy to install.

This is achieved by the features of claim 1 according to the invention.

This results in the advantage that the road banquet plates together form a composite by the connecting means on the side surfaces, whereby the individual road banquet plates can be formed with low mass but still a strong retention effect of the road banquet plates against displacement is achieved. Because of the possible low Mass the road banquet plates can also be laid by hand, whereby the effort for laying is significantly reduced. By the slope of the side surfaces to each other, wherein the individual connection means can be selectively connected to the same connection device or the other connection means of the adjacent street banquet plate, the road banquet plates can optionally be placed straight or following a curve in both directions, and still remain connected to each other, with gaps between adjacent street banquet plates can be avoided. As a result, the roadway edge can be reliably supported, especially in curves or in the area of roundabouts, where the roadway edges are often exposed to increased loads.

The subclaims relate to further advantageous embodiments of the invention.

It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
