【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. A double floor formed by the supporting device according to the present invention is shown in FIGS. In this embodiment, the supporting device has columns 2 standing upright on the floor base 1 and panel receivers 3 mounted on the columns 2, and the panel receivers 3 support the back surfaces of the four corners to form a grid pattern. Panel pressers 11 are attached to the abutting corners of the plurality of laid floor panels 4, 4 to fix the floor panel 4.

As shown in detail in FIG. 3, the column 2 has a fixing member 5 and a screw rod 6 which are adhered and fixed to the floor base 1, and the installation position is provided at the center of each side edge of the fixing member 5. A notch 12 for locating the is cut out. A plurality of adhesive flow holes 13, 13, ... Are drilled in the fixing member 5, and the fixing member 5 is fixed after the floor base 1 or the fixing member 5 is coated with the adhesive. When pressed against the floor base 1, the adhesive overflows from the holes 13 and functions as a wedge. Further, the central portion of the fixing member 5 is slightly bulged upward, and the mounting opening 9 is opened at the center thereof.

On the other hand, the threaded rod 6 is provided with a screw portion 14 and a skirt portion 7 whose diameter gradually expands from the terminal end of the screw portion 14 toward the material end. The diameter of the hem portion 7 at the material end is substantially equal to the outer diameter of the bulge portion 15 of the fixed member 5, and a positioning projection 10 is provided on the rear surface of the center portion of the hem portion 7 while leaving a seat surface 8 at the peripheral portion. To be done.

The positioning protrusion 10 is formed to have a diameter slightly smaller than that of the mounting opening 9 of the fixing member 5, and in a state of being inserted into the mounting opening 9, the standing position of the screw rod 6 on the fixing member 5 is positioned. To be done. In this embodiment, a connecting radius 16 is formed at the boundary between the threaded portion 14 and the hem 7 of the threaded rod 6 to prevent stress concentration at the end of the threaded portion 14.

Thus, the support column 2 is formed by inserting the positioning protrusion 10 into the mounting opening 9 of the fixing member 5 and then welding the periphery thereof. In this state, the end face of the hem portion 7 is wide. Since the area is fixed to the fixing member 5, the bending moment is sufficiently reinforced and the stress concentration on the screw portion 14 is efficiently prevented.

On the other hand, the panel receiver 3 is formed by mounting a cover member 18 made of synthetic resin on the upper surface of the panel receiving body 17 made of a metal material, and the caulking nut 19 fixed to the central portion of the panel receiving body 17.

Therefore, in this embodiment, first, the pillar 2 is erected on the floor base 1 with the panel receiver 3 assembled to the pillar 2. When fixing the columns 2, it is particularly important that the screw rods 6 stand upright on the floor base 1 at equal pitches, but the position of the screw rods 6 with respect to the fixing member 5 is accurately determined. Positioning of the column 2 on the sill 2 is sufficient to align the marking line 20 with the notch 12 of the fixing member 5, as shown in FIG.

After the columns 2 are fixed to the floor base 1 as described above, the panel receiver 3 is rotated around the screw rod 6 to level the upper surface of the panel receiver 3, and then the floor panel 4 is opened. The floor panel 4 is laid on the panel receiver 3 so that the guide hole 21 is fitted into the guide protrusion 22 of the panel receiver 3, and the tool is inserted from the circular hole formed in the abutting portion of the floor panel 4. Then, the nut 23 is tightened to fix the panel receiver 3.

The panel retainer 11 attached to the abutting portion of the floor panel 4 laid as described above has a head 25 for retaining the depressions 24 provided at the four corners of each floor panel 4, It is composed of a shaft portion 27 protruding from the head portion 25 and provided with a locking projection portion 26 at the lower end thereof. After the shaft portion 27 is inserted into a fitting hole 28 provided in the panel receiver 3, the head portion 25 is fixed by a jig. It is locked in the fitting hole 28 by rotating it by about 45 ° using the above.

In the above description, the case where the screw rod 6 is fixed to the plate-shaped fixing member 5 has been shown, but outside this, as shown in FIG. 4, the pipe body 30 is formed by fixing the pipe body 30 to the flat plate 29. It can be fixed to the fixing member 5 and the notch 31 for preventing interference with the joint bead of the pipe body 30 is provided in the hem portion 7 of the screw rod 6 so as to be able to meet such specifications.
