DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 and 2 show a double floor installed by the support device according to the present invention. In this embodiment, the supporting device comprises a support 2 fixed to the floor base 1.
And a panel holder 5 mounted on the upper end of the support column 2 and supporting the back surfaces of the four corners of the floor panel 4, a panel presser 6 mounted on the abutting portion of the floor panel 4, and locking the panel presser 6. And a panel press receiver 12 for use.

The support column 2 includes a fixed plate 16 adhered and fixed to the floor base 1 and a screw rod 17 erected at the center of the fixed plate 16.
The notch 18 for positioning the installation position is cut out at the center of each side edge of the fixing plate 16. In FIG. 2, reference numeral 19 denotes a hole for adhesive flow.

As shown in detail in FIGS. 3 and 4, the panel receiver 5 is formed of a metal plate, and is mounted so as to be adjustable in height by screwing a caulking nut 20 joined to a central portion into a screw 17. . Note that a reinforcing washer 21 is interposed between the caulking nut 20 and the panel receiver 5 to reinforce the central portion of the panel receiver 5.

The panel retainer 12 is a member made of a synthetic resin having a rectangular bulge 22 at the center and a hanging wall 23 at the periphery so as to cover the periphery of the panel receiver 5. The hook portion 24 projecting downward from the wall 23 is elastically locked to the peripheral edge of the panel receiver 5, and the locking hook 15 hanging down from the ceiling portion of the bulging portion 22 to the rear surface is locked to the locking hole of the panel receiver 5. 14 and attached.

As will be described later, the panel receiver 5 and the panel holding receiver 12 are mounted on the column 2 in a sub-assembly state. A fixed washer 25 is disposed on the upper surface of the panel receiver 5. In order to position the fixed washer 25 in the sub-assembly state, the panel receiver 5 includes
A pressing piece 27 is provided on the panel holding receiver 12 for the positioning protrusion 26 to hold the fixed washer 25 from above.

The wall surface of the bulging portion 22 is inclined toward the center as it goes upward, and restricts the movement of a positioning chamfering portion 28 of the floor panel 4 described later.
Further, an engagement hole 11 having a rectangular hole 29 on the side is opened in the ceiling of the bulging portion 22 to receive the panel presser 6. Note that a cam surface 13 is formed on the periphery of the back surface of the engagement hole 11.

Accordingly, in this embodiment, first, the fixed washer 25 is mounted on the center of the panel receiver 5, and then the panel presser receiver 12 is resiliently mounted. In this state,
The upper surface portion of the panel receiver 5, that is, the contact portion with the floor panel 4 is entirely covered with the panel holding receiver 12 made of synthetic resin, thereby preventing the metal contact of the floor panel 4 and the panel receiver 5. Is covered with the hanging wall 23 to prevent rust from being generated from the cut end face of the panel receiver 5 and to prevent the cable from being damaged by the cut end face. Thereafter, the subassembly of the panel receiver 5 and the panel holder 12 is connected to the screw 17 of the column 2.
After that, the support 2 is fixed to the floor base 1, and further,
After adjusting the installation height, the nut is loosely tightened from above the panel receiver 5 and held at a predetermined height on the floor base 1.

On the other hand, as shown in detail in FIG. 5, the floor panel 4 comprises an upper panel 30a and a back panel 30b joined at the periphery of the upper panel 30a.
It is formed by filling a hollow portion between the upper panel 30a and the rear panel 30b with an inorganic filler 30c.

The floor panel 4 has positioning chamfers 28 at four corners. This positioning chamfer 28
Has an inclined wall surface that matches the inclined portion formed in the bulging portion 22 of the panel receiver 5, and further, the four corners of the floor panel 4 are depressed in a quadrant shape. Is provided with a notch 3 which becomes a circular hole in the abutting state.

Therefore, in this embodiment, the guide holes 32 formed in the floor panel 4 are
Floor panel 4 so as to fit into
Is laid on the panel receiver 5, each floor panel 4
The positioning chamfered portion 28 is dropped and positioned along the inclined surface of the bulging portion 22 on the panel receiver 5 side, and the subsequent lateral movement is regulated. Furthermore, floor panel 4
The panel receiver 5 is placed in a state where idling is prevented between the column 2 and the support column 2. Therefore, a tool is inserted from the circular hole formed by the notch 3 to tighten the nut 34, and the panel receiver 5 is fixed. I do.

Next, the panel retainer 6 is attached to each floor panel 4.
Head 7 for pressing depression 31 from above,
And a shaft portion 9 inserted through the engagement hole 11 of the panel press receiver 12, and a locking projection 10 inserted through a rectangular hole 29 of the panel press receiver 12 at the lower end of the shaft portion 9 in a radial manner. It is protruding.

Thus, after laying the floor panel 4,
The shaft portion 9 is inserted into the engagement hole 11 of the panel holding receiver 12,
When the head 7 is rotated by approximately 45 ° using a jig or the like, the locking projection 10 is pulled downward by the cam surface 13 while the bulging portion 22 bends, and the head 7 is moved to the concave portion 3 of each floor panel 4.
By pressing 1, the floor panel 4 is prevented from rising or slipping.

At this time, as shown in FIG. 1, the deformation of the panel retainer 12 is performed by setting the contact portion with the floor panel 4 to the fulcrum 3.
5 and a contact portion with the back surface of the recessed portion 31 of the floor panel 4 is formed as an action point 36, so that the bending distance becomes longer,
Variations in the clamping force are prevented.

[0022]

As is apparent from the above description, according to the present invention, the reaction force of the panel press is obtained by elastically bending the panel press receiver formed of a synthetic resin material. The floor panel can be stably fixed by the panel retainer for a long period of time.

Further, in the case where the locking hook hanging down from the peripheral edge of the engaging hole of the panel pressing receiver is configured to be locked to the panel receiving, the panel pressing receiving is near the point of application of the deformation load, and Since the panel holder is locked to the panel receiver in the direction in which the load acts, it is possible to prevent the panel holder from floating unnecessarily from the panel receiver.

Further, when the panel retainer is formed of a synthetic resin material, the operability can be improved because the contact portion with the panel retainer slides well.
