There is a demand for increasing the rigidity and strength of the floor panel support without increasing the height of the floor structure including the floor panel and the floor panel support. In this case, increasing the thickness of the floor panel receiver is disadvantageous because the cost of the floor panel receiver material increases. Therefore, it is conceivable that the reinforcing member is welded to the floor plate receiver, but in the connection structure of FIG. 11A, there is almost no space between the frame members 103 and 104 at the floor plate joint, so that the connection structure is somewhat large. The reinforcing member cannot be arranged. This is the same in the connection structure of FIG.

Moreover, since the frame members 103 and 104 of the floorboard are not symmetrical, there is no symmetry of the floorboard with respect to an intermediate line between the joint ends of the floorboard, and the material management of the frame material and the floorboard This is disadvantageous in terms of parts management and also in terms of material cost of the frame material. Also, the frame material 1 is placed on the projecting piece 104b of the frame material 104.
Since the protruding pieces 103b of No. 03 are assembled in an overlapping manner, it is not possible to assemble or remove the individual floorboards alone when assembling or repairing the floorboards, which is disadvantageous in terms of assembly and repair. An object of the present invention is to make it possible to arrange a reinforcing member for reinforcing a floorboard support without increasing the height of the floor structure in a connection structure between a floorboard and a floorboard support at a floorboard joint, To ensure the symmetry of the floorboards,
And so on.
