Further, the floor panel 2 is formed in a substantially square shape, and the upper panel 17 and the lower panel 18 are overlapped and integrated in a hollow shape, and an inorganic filler 19 such as mortar is sealed in the hollow portion. . The corner 2b has a step 2c with which the panel holder 9 is engaged.

Now, as shown in FIG. 5 to FIG. 7, at the end of the floor panel 2, the upper panel 17 and the lower panel 18 are provided.
, A through hole 20 is formed, and a holder 21 is buried in the through hole 20 to form an engaging hole 16.
The holder 21 is provided with a rib 22 and a retaining portion 23 on the outer peripheral surface and a flange portion 25 on the peripheral edge of the opening 24 at the lower end, while the opening side of the inner peripheral surface is formed in a tapered shape. ing. The dimensional accuracy of the holder 21 is enhanced by injection molding of a resin. This holder 21 has a through hole 20 before filling the filler when molding the floor panel.
The filling material 19 that is attached to the
The upper and lower ends thereof are held firmly by fitting into the ribs 22 and the retaining portions 23 of the through holes 20, and burrings 26 and 27 formed on the peripheral portions of the upper panel 17 and the lower panel 18 of the through hole 20. Deformation is prevented. The engaging hole 16 having such a structure facilitates the fitting operation by guiding the engaging projection 15 of the panel receiving base 6 with a tapered portion when the floor panel 2 is mounted, and facilitates the fitting operation. The engagement protrusion 15 is fitted in a tight contact state to prevent the floor panel 2 from moving in the horizontal direction and rattling.

As shown in FIGS. 2 to 4, the above-mentioned floor panel 2 is formed by assembling four sheets on the panel receiver 6 and then engaging the panel holder 9 with the panel holder 8. Thereby, the step 2c of the corner 2b is fastened with one touch.

As shown in detail in FIGS. 8 and 9, the panel holding receiver 8 slidably inserts a holding member 28 through a collar 29 into a mounting bolt 30 and further holds the mounting bolt 30 with a head 30a. With a spring washer 31 interposed between the members 28,
It is arranged at the center of the upper surface of the panel support 6. Here, the panel holding member 9 is engaged with the panel holding receiver 8 and is rotated by a predetermined angle (about 90 degrees), so that a holding member is formed.
