DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. 1 and 2 show a double floor installed by the supporting device according to the present invention. In this embodiment, the support device comprises a column 2 fixed to a floor base 1.
A panel holder 3 that is mounted on the upper ends of the columns 2 and supports the back surfaces of the four corners of the floor panel 4, a panel retainer 5 that is attached to the abutting portion of the floor panel 4, and the panel retainer 5 is locked. And a panel retainer 6 for holding.

The column 2 has a fixing plate 12 and a screw rod 13 which are adhered and fixed to the floor base 1, and a notch 12a for positioning the installation position is formed at the center of each side edge of the fixing plate 12. Missing. In FIG. 2, reference numeral 12b indicates a hole for adhesive flow.

The panel receiver 3 is formed of a metal plate material, and as shown in detail in FIGS. 3 and 4, the caulking nut 14 joined to the center is screwed into the screw rod 13 so that the height can be adjusted. .. A reinforcing washer 15 is interposed between the crimp nut 14 and the panel receiver 3. The reinforcing washer 15 is formed with a diameter and a thickness sufficient to prevent the panel receiver 3 from being deformed when a load from the floor panel 4 is applied to the panel receiver 3, and is tightened together when the caulking nut 14 is crimped. To be done.

The panel retainer 6 is a synthetic resin member having a rectangular bulge 7 in the center and a hanging wall 9 on the periphery so as to cover the periphery of the panel receiver 3. Hook portion 16 protruding downward from the wall 9
Is elastically locked to the peripheral edge of the panel receiver 3, and the locking claws 8 hanging from the ceiling of the bulging portion 7 to the back surface are locked in the locking holes 17 of the panel receiver 3.
A fitting hole 7a having a back surface as a cam surface 7b is formed in the ceiling portion of the bulging portion 7 to receive the panel retainer 5.

As will be described later, the panel support 3 has the support 2 with the panel retainer 6 sub-assembled on the upper surface thereof.
A fixed washer 18 is arranged on the upper surface of the panel receiver 3 in order to prevent wobbling and the like when it is mounted on the column 2. In order to position the fixed washer 18 in the sub-assembled state of the panel receiver 3, a projection 19 for positioning is formed on the panel receiver 3, and the panel presser retainer 6 presses the fixed washer 18 from above. 20 is formed. The central portion of the fixed washer 18 is bulged slightly upward in order to prevent interference with the caulking allowance of the caulking nut 14.

The wall surface of the bulging portion 7 is an inclined surface 21 that is directed toward the center as it goes upward and has a skirt with an arcuate surface. The chamfered portion for positioning the floor panel 4, which will be described later, is provided. 22 movement is regulated.

Therefore, in this embodiment, first, the fixed washer 18 is attached to the central portion of the panel receiver 3, and then the panel retainer 6 is elastically attached. In this state, the upper surface portion of the panel receiver 3, that is, the contact portion with the floor panel 4 is entirely covered with the panel retainer 6 made of synthetic resin, which prevents metal contact of the floor panel 4 and The peripheral edge of the panel receiver 3 is covered with the hanging wall 9 to prevent rust from being generated from the cut end surface of the panel receiver 3, and to prevent the cable from being damaged by the cut end surface. After this, after subassemblies of the panel receiver 3 and the panel retainer 6 are screwed into the screw rods 13 of the support columns 2, the support columns 2 are fixed to the floor base 1, and after the installation height is adjusted, The nut 23 is loosely tightened from above the panel receiver 3 and held at a predetermined height above the floor base 1.

On the other hand, as shown in FIG. 5, the floor panel 4 comprises a top panel 24 and a back panel 25 joined at the peripheral edge of the top panel 24.
4 and the back panel 25, the inorganic filler 26
Are formed by filling.

The floor panel 4 is provided with positioning chamfers 22 on the four corner side walls. This positioning chamfer 22
Has an inclined wall surface that matches the inclined surface 21 formed on the bulging portion 7 of the panel receiver 3, and the lower end portion thereof has an arcuate surface that matches the arcuate surface of the bulging portion 7. Further, the floor panel 4 is dented in a quadrant shape at the four corners,
A concentric notch 28 is formed at the tip of the recess 27.

Therefore, in this embodiment, when the floor panel 4 is laid on the panel receiver 3 so that the guide hole 4a of the floor panel 4 is fitted into the guide projection 5a of the panel pressing receiver 6, each floor panel 4 is positioned for positioning. The chamfered portion 22 is dropped along the inclined surface 21 of the bulging portion 7 on the side of the panel receiver 3 and positioned, and the subsequent movement in the lateral direction is restricted (see FIG. 6). Furthermore, since the panel receiver 3 is placed in a state in which idling is prevented between the panel receiver 3 and the support column 2 by mounting the floor panel 4, the cutout 28 of the floor panel 4 is formed.
Insert the tool through the circular hole formed by
Tighten 3 and fix the panel receiver 3. Nut 23
By tightening the
5 and the fixed washer 18 are fixed to a predetermined height in a state where the front and back surfaces are sandwiched, and wobble and the like are completely prevented.

Next, as shown in FIGS. 1 and 2, the panel retainer 5 has a head 29 housed in a recess formed by the recess 27 of each floor panel 4, and a protrusion from the head 29. And a shaft portion 30 which is inserted into a hole formed by the notch 28 of the floor panel 4, and a locking projection 31 is radially provided at a lower end of the shaft portion 30.

After laying the floor panel 4,
When the shaft portion 30 is inserted into the fitting hole 7a of the panel receiver 3 and the head portion 29 is rotated by about 45 ° using a jig or the like, the bulging portion 7 bends and the locking projection portion 31 is moved by the cam surface 7b. The head portion 29 is pulled downward, and the head portion 29 has a recess 27 in each floor panel 4.
Is pressed to prevent the floor panel 4 from floating or shifting.

The deformation of the panel retainer 6 when the panel retainer 5 is mounted is caused by the fulcrum 32 in the vicinity of the arcuate surface pressed by the floor panel 4 and the depression 27 as the point of action. d becomes longer, and variation in tightening force is prevented (see FIG. 1).

[0022]

As is apparent from the above description, according to the present invention, the panel retainer made of synthetic resin is mounted on the upper surface of the panel retainer, and the floor panel is positioned at the central portion of the panel retainer. Since the bulging part is provided, the floor panel can be laid at an accurate position, and the floor panel can be slanted by simply inserting the guide hole into the guide protrusion of the panel retainer and dropping it. Since it is guided to the regular position along the surface, the workability of construction can be improved.

Further, when the peripheral edge of the panel receiver is completely covered with the panel retainer, metal contact between the floor panel and the panel receiver is prevented, so that rattling noise and the like can be prevented.

Further, since the cut edge of the panel receiver is covered with the panel retainer, it is possible to prevent corrosion from the edge and to reduce the manufacturing cost by eliminating the need for plating the panel receiver. In addition, the cable disposed under the floor is not damaged.

In addition, when the panel retainer is provided with a locking claw that is hung from the back surface of the bulge and the locking claw is elastically locked to the panel retainer, the panel retainer receives the deformation load. Since the panel retainer is locked near the point of action and in the direction of action of the load, it is possible to prevent the panel retainer from inadvertently rising from the panel retainer.
