Is a long flat plate having a length substantially equal to that of the frame 4 and a width substantially equal to one third of the frame 4, and the three flooring materials 5 are attached side by side to attach the frame 4. The entire top surface is covered. That is, this floor panel P is a form in which the face material, which is a plywood in a conventional general floor panel, is transformed into flooring materials 5,5,5.

The flooring material 5 is widely commercially available as a floor finishing material, and has parallel joints 6 formed at equal intervals on the surface thereof, and the flooring material 5 is provided between the flooring materials 5 and 5. A similar joint 6 is formed in the same manner.

Further, a reinforcing plate 7 whose length and width are slightly reduced by the flooring material 5 is integrally attached to the lower surface of the flooring material 5 so that a step is formed at the outer peripheral edge of the lower surface of the flooring material 5. The steps are engaged with the frames 1, 2, 3 so that the steps are positioned with respect to the flooring material 5 frame 4 and attached without lateral displacement.

Around the flooring material 5 thus attached to the upper surface of the frame 4, the vertical frame 1 located on the outer peripheral edge upper surface 4 a of the frame 4, that is, the outer periphery of the frame 4.
In addition, the upper surface of the outer peripheral edge of the side frame 2 is exposed, and the width of the exposed portion is set to one half of the interval between the joints 6 formed on the surface of the flooring material 5. ing.

To construct a floor using the floor panel P, first,
The joints 6 formed on the surface of the flooring material 5 of each floor panel P are parallel to each other so that the side surfaces 4a
That is, the side surfaces of the vertical frame 1 located on the outer periphery of the frame 4 are closely laid and arranged. Thereby, the flooring materials 5,5 of the floor panels P, P laid next to each other
A groove 10 having a width equal to the interval between the joints 6 is formed therebetween, and the outer peripheral edge upper surfaces 4a, 4a, of both frames 4, 4 are formed in the groove 10.
4a is exposed, and the connecting fitting 11 is driven there.
