Embodiment Construction

[0011] The plates 1-6 are for example rectangular, identical and parallel to each other.

[0012] Figure 1 shows the storage state of the structure, and Figure 2 shows the use state spread out on the ground.

[0013] The panels 1-6 are connected by a flexible band B which is fixed successively to half the surface of each panel and preferably covers its entire length.

[0014] Between two successive panels, the strip B defines a hinged connection area L forming a hinge and connecting the edge of one panel to the middle of the next panel.

[0015] Figures 3-5 show the unrolling of the panels 1-6 of Figure 1 in order to achieve the double cover layer shown in Figure 2, the panels being stacked in a staggered fashion and all aligned in the same direction, which is the same as when fully unrolled When the transverse axes of the strips B are parallel, the strips B are sandwiched between two plies, and more particularly are contiguous.

[0016] Figures 6 and 7 show another variant ...

Abstract

The invention concerns a fast unfolding two-layer temporary flooring structure consisting of preferably rigid plates (1 to 6), made of a suitable material. The invention is characterized in that said plates (1 to 6) are arranged mutually parallel and cascade-linked by an articulated linking element (B) so that between two consecutive plates, said element (B) is linked to an edge of the other plates, and also preferably in a central zone of the other plate, said elements defining hinge lines between parallel planes with longitudinal or transverse axis of the plates.

Description

technical field [0001] The present invention relates to a temporary double-layer rapidly spreading ground covering structure. Background technique [0002] From WO 97 / 21870 is known a mat consisting of worn motor vehicle tires for reinforcing or supporting the rails of a transverse road, wherein the tire sides of circular rings are arranged in an array, the tire sides overlapping or connected to each other together. [0003] DE 26 36 983 discloses a driveway slab for leveling roads in poorly shaped areas. The board includes upper and lower metal sheets, and the space between the upper and lower metal sheets is filled with expanded polystyrene. However, these temporary ground cover structures are not satisfactory. Contents of the invention [0004] The object of the present invention is to propose a structure formed of panels, for example rectangular panels of rigid monolithic panels made of plastic or composite material, which can be rolled out easily and quickly to for...
