It may interfere with the fixing of the composite floor panel to the beam and the fitting with the outer wall panel.

For this reason, a means for avoiding collision with the outer wall panel by mounting the ALC composite floor panel on an appropriate supporting metal fitting arranged on the indoor side of the beam is also proposed. Since the ALC composite floor panel cannot be fixed directly, the mounting strength tends to be poor, and a new support metal piece must be separately prepared and mounted, which lowers cost performance and workability.

According to the present invention, one side of the floor panel is formed with a projecting portion at which one end of the base panel projects from the concrete board.
In addition, by inserting this projecting portion into the space between the lower end surface of the outer wall panel and the support surface provided on the upper surface of the beam, and placing the base panel on the support surface, the end surface of the concrete board becomes the inner surface of the outer wall panel. Basically, the floor panel should be placed on the indoor side rather than using a new support fixture for fixing the floor panel, and the floor panel should be placed directly and firmly on the beam without any interference with the outer wall panel. It is intended to provide a floor panel mounting structure that can be fixed by fixing.
