Mobile structure for adapting surfaces

A mobile structure for forming a surface comprising:

• a grid assembly, arranged on telescopic columns supporting the grid assembly, one end of each of the telescopic columns forming a grid node, the telescopic columns individually extendable in order to place each grip node of the grid assembly at different heights;
• telescoping ties interconnect each grid node;
• grid gaps formed between the ties and delimited by the ties;
• telescoping cross pieces, one of each of the cross pieces extends between and connected to two adjacent ties in each of the grid gaps;
• plates closing grid gaps arranged in the grid assembly for supporting a covering determining the surface to be formed, each of the plates secured in a hinged manner at an edge to one of the ties in one of the grid gaps, the one of the ties opposite the one of the cross pieces in each of the grid gaps, and each of the plates arranged freely sliding on the one of the cross pieces, allowing the dimensional variation of the grid assembly in the adaptation to the shapes of the surfaces.
