ASSEMBLING APPARATUS OF FLOOR PANEL FOR CONSTRUCTION

The present invention relates to an apparatus of assembling floor panels for construction that installs the floor panels on a support means installed to a floor structure of a building to form a lower space for an electric wiring or other facility, or cooling and heating pipes. In particular, a floor panel (20) having a stepped hole (21) for assembly, and a guide bushing (25) having a bolt insertion hole (26) is inserted into the stepped hole from the top. An upper support plate (11) of a support member (10) is formed with a flange (15) by burring, and a screw hole (16) is formed in the flange. A bolt (40) is screwed to the bolt insertion hole (26) of the floor panel (20) to fix the floor panel. Therefore, the configuration is simple to reduce the production costs and the construction costs and improve the construction workability. The engaging rigidity of the floor panels is improved, and there is no portion protruding toward the lower portion of the floor panel, so that a barrier structure (frame structure) blocking the flow of the cooling and heating air-condition is avoided, thereby improving the cooling and heating air-conditioning efficiency.
