<p>The present invention is configured from a floor panel and a support leg. The support leg is provided with an upright support column at a base plate, and a seat is penetrated by the support column and is attached in a manner such that the vertical position can be adjusted. The floor panel is configured from a primary plate and a reinforcing steel plate. The primary plate is a compression molded calcium silicate board, the four peripheral lateral surfaces are provided with a perpendicular surface and, underneath same, a tapered surface that is inclined in the in-plane direction, and has a scooped concavity at the four corners at the bottom surface side that receive the apex of the support column. The four corners of the reinforcing steel plate are folded upwards in a rib shape along the tapered surface of the primary plate, and are notched at the four corners, exposing the scooped concavity.</p> |
