あった。<< Prior Art >> Conventionally, a floor on which a computer system or OA equipment is installed is often a double floor for wiring electric wiring equipment. Such a double floor structure is a floor of a building body. In general, metal columns are erected on a slab, and multiple floor panels of a certain size are aligned vertically and horizontally while supporting the joints of each floor panel on the columns. In such a conventional double floor structure, although each floor panel is fixed to the columns, the floor panels are not fixed to each other, so if the earthquake or the vibration generated from the equipment is large, the floor panel is fixed. There was a fear that the adjacent part of the floor would rise and that the floor panel might fall off.
