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. A double floor to which the present invention is applied is shown in FIGS. 1 and 2. In this embodiment, a pillar 2 is erected on the floor base 1, and a plurality of floor panels 5, 5 ... Are supported in a lattice by supporting the back surfaces of the four corners by a panel receiver 3 attached to the upper end of the pillar 2. It is arranged.

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 14 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 15 indicates a hole for adhesive flow.

As shown in detail in FIG. 3 and FIG. 4, the panel receiver 3 has a crimp nut 17 at the center through a reinforcing plate 16.
It is formed by mounting a cover member 19 made of synthetic resin on the upper surface of the panel receiving body 18 to which is fixed. The reinforcing plate 16 is formed with a diameter and thickness sufficient to prevent the panel receiving body 18 from being deformed when a load from the floor panel 5 is applied to the panel receiving 3, and is tightened together when the caulking nut 17 is caulked. It

Further, the cover member 19 is provided with a rectangular bulge portion 8 in the center portion and a hanging wall 20 at the peripheral edge so as to cover the peripheral edge of the panel receiving main body 18, and the downward wall from the hanging wall 20. The hook portion 21 projecting from the panel is elastically locked to the peripheral edge of the panel receiving body 18, and the connecting hook 22 hanging from the ceiling of the bulging portion 8 to the back surface is engaged with the locking hole 23 of the panel receiving body 18. It is installed by stopping it.

As will be described later, the panel receiver 3 includes
The cover member 19 is sub-assembled on the upper surface and is mounted on the column 2. A fixed washer 24 is arranged on the upper surface of the panel receiving main body 18 in order to prevent wobbling or the like during mounting on the column 2. In order to position the fixed washer 24 when the panel receiver 3 is in the sub-assembled state, the panel receiving body 18 is provided with a positioning projection 2
5, the cover member 19 is formed with a pressing piece 26 for pressing the fixed washer 24 from above.
The central portion of the fixed washer 24 is slightly bulged upward in order to prevent interference with the caulking allowance of the caulking nut 17.

The wall surface of the bulging portion 8 is formed as an inclined surface toward the center as it goes upward, and regulates the movement of the positioning chamfer 27 of the floor panel 5 as described later. The bulging portion 8 has an arcuate receiving surface 7 at the hem, and in order to support an arcuate surface 28 of the floor panel 5 described later on the arcuate receiving surface 7, the outside thereof is a lower surface. Was
A guide protrusion 30 is provided so as to project upward from the step portion 29.

A fitting hole 32, which is formed by radially extending four rectangular holes 31, is formed in the ceiling of the bulging portion 8 to receive a panel retainer 6 described later. A cam surface 33 is formed on the periphery of the back surface of the fitting hole 32.

On the other hand, as shown in detail in FIG. 5, the floor panel 5 includes a top panel 34a and a top panel 34a.
And a back panel 34b joined at the peripheral edge of the back panel 34b, and is formed by filling a hollow space between the top panel 34a and the back panel 34b with an inorganic filler 34c.

The back surface bulging portion 35 of the floor panel 5 formed by the back surface panel 34c has positioning chamfers 27 at the four corners. The positioning chamfer 27 has an inclined wall surface that matches the inclined surface formed on the bulge 8 of the panel receiver 3, and the lower end portion thereof has an arcuate surface 28 that matches the arcuate receiving surface 7 of the cover member 19. Is supported by the panel receiver 3 with the arcuate surface 28 slidingly contacting the arcuate receiving surface 7. Further, the floor panel 5 is dented in a quadrant shape at the four corners, and a notch 4 which becomes a circular hole 9 at the time of abutment is concentrically provided at the tip of the dent 36.

Therefore, in this embodiment, first, the floor base 1 with the panel support 3 assembled to the column 2 is assembled.
The pillar 2 is erected on the floor base 1, and then the panel support 3
Is rotated to level the upper surface of the panel receiver 3.
After that, when the floor panel 5 is laid on the panel receiver 3 by fitting the guide holes 37 formed in the floor panel 5 into the guide protrusions 30 of the panel receiver 3, as shown in FIGS. 5, the positioning chamfered portion 27 is dropped and positioned along the inclined surface of the bulging portion 8 on the panel receiving 3 side, and the subsequent lateral movement is restricted. Further, since the panel receiver 3 is placed in a state in which idling is prevented between the floor bracket 5 and the support column 2 by inserting the floor panel 5, a tool is inserted through the circular hole 9 formed in the abutting corner of the floor panel 5. And tighten the nut 38 to fix the panel receiver 3. By tightening the nut 38, the panel receiver 3 is fixed to a predetermined height in a state where the front and back surfaces are sandwiched between the reinforcing plate 16 and the fixed washer 24, and wobbling is completely prevented.

A panel retainer 6 is attached to the abutting portion of the floor panel 5 laid as described above. The panel retainer 6 includes a head portion 39 housed in a recess formed by the recessed portion 36 of each floor panel 5, and a shaft portion 40 protruding from the head portion 39 and inserted into the circular hole 9. Part 4
At the lower end of 0, locking projections 41 that are inserted into the rectangular holes 31 of the panel retainer 6 are radially provided.

After laying the floor panel 5,
When the shaft portion 40 is inserted into the fitting hole 32 of the panel receiver 3 and the head portion 39 is rotated by about 45 ° using a jig or the like, the bulging portion 8 and the vicinity thereof are bent, and the locking projection portion 41 is released. The head surface 39 presses the concave portion by being pulled downward by the cam surface 33, so that the floor panel 5 is prevented from rising or shifting.

The deformation of the panel receiver 3 when the panel retainer 6 is mounted is generated by using the vicinity of the arcuate surface 28 retained by the floor panel 5 as a fulcrum and the back surface of the recess 36 as the point of action. The distance is lengthened and the tightening force is prevented from varying.

[0021]

As is apparent from the above description, according to the present invention, since the bulging portion for positioning the floor panel is provided in the central portion of the panel receiver, the floor panel can be laid in an accurate position. In addition, since the floor panel is guided to the regular position along the inclined surface of the bulging portion, the workability of construction can be improved.

Further, since the floor panel is supported by the arcuate receiving surface formed on the skirt of the bulge of the panel receiver, the load point of the floor panel approaches the center of the column and the arcuate receiving surface Since the tilt of the pillar is absorbed, the step difference between the floor panels due to the tilt of the pillar can be minimized.
