Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a support structure for a floor panel in which the floor panel is supported by a plurality of support devices arranged on a reference floor surface.

(Prior Art) Conventionally, in a raised floor in which a floor panel and a support device are separate, a pedestal board is fixed on a reference floor surface, and an acid screw portion integrally formed on the pedestal board is fixed. The male screw part of the support leg is screwed into the support leg, and the panel holder provided on the upper part of the support leg is formed with a vertical protrusion by an integral bending process to guide the floor panel. A support structure for a floor panel is known in which a protruding part of a stand and a hole in the floor panel are engaged (Utility Model Publication No. 63-4
0429).

(Problem to be Solved by the Invention) However, since the upper end of the acid screw portion of the pedestal board described above is set at a constant height in order to support the support legs,
There is a problem that a large amount of bending moment acts on this pedestal board, causing it to fall over.

In addition, since this pedestal board does not have a mechanism to allow the support legs to stand upright in a tiltable manner, if the pedestal board cannot be fixed horizontally due to unevenness of the reference floor surface, the support legs should be moved vertically. It was difficult to install it upright.

Furthermore, since the protrusions of the panel holder that engage with the floor panel are formed in the shape of a vertical plate, they have a narrow tolerance for errors and are not sufficiently effective in guiding the floor panel. The holes in the floor panel are integrally molded using a press, etc., and the dimensional accuracy becomes unstable, which tends to create gaps between the holes and the protruding parts.As a result, the movement of the floor panel cannot be held in a controlled manner. There was a problem that a structure could not be formed.

Therefore, an object of the present invention is to provide a support structure for a floor panel that has excellent seismic performance and workability by forming a rigid frame structure with a floor panel and a support device.

(Means for Solving the Problems) In order to achieve the above object, the floor panel support structure of the present invention supports the floor panel by a plurality of support devices arranged on a reference floor surface. A pedestal board is fixed to the reference floor surface, support legs are swingably erected via adjustment nuts, and a panel pedestal is provided on which a corner of the floor panel is placed on the upper part of the support leg. The guide wall of the panel holder and the side wall of the corner of the floor panel are integrally provided, and the guide wall of the panel holder and the side wall of the corner of the floor panel are engaged in a matching manner, and a resin holder is provided between the engagement protrusion of the panel holder and the floor panel. The structure is characterized in that the floor panel is tightly fitted into an engagement hole formed by embedding, and the floor panel is tightly fixed to the panel holder by a panel presser.

(Function) According to such a floor panel support structure, the support legs are swingably erected on the pedestal board fixed to the reference floor surface,
A floor panel is fixed in close contact between panel holders provided on the upper part of the support legs. That is, the upper end of the support leg is rigidly connected to the floor panel, and the lower end is connected with a pin, thereby reducing the bending moment acting on the pedestal board.

Further, since the support legs can swing in any direction relative to the pedestal board, the support legs can always be vertically erected regardless of the mounting angle of the pedestal board.

Then, the floor panel is placed in a predetermined position with its side wall guided by the guide wall of the panel holder, and the engagement protrusion of the panel holder and the engagement hole formed by the resin of the floor panel are in close contact with each other. The engagement positions the floor panel vertically and accurately with respect to the support leg, and improves its integrity with the support leg.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the floor panel support device 1 includes a pedestal base plate 4 having a threaded portion 3 integrally provided at the center of its upper surface, and an adjustment nut 5 screwed into the threaded portion 3. , is swingably erected on the adjustment nut 5 and has a panel holder 6 on the top.
The support leg 7 and the panel presser holder 8 are integrally provided.
The panel retainer 9 engages with the floor panel 2 to tighten and fix the floor panel 2. .

The pedestal base plate 4 is fixed at a predetermined position on the reference floor surface 10 by means such as an adhesive, and an adjustment nut 5 is screwed into the screw portion 3 thereof.

The adjusting nut 5 has a heightwise position relative to the pedestal base plate 4 set by a rotation operation, and has a 7-lung portion 5a that supports the lower end of the support leg 7, and a tapered cone-shaped upper portion with a reduced diameter. Since the support leg 7 is loosely engaged with the adjustment nut 5, it can be erected upright so as to be able to swing around its lower end with respect to the pedestal base plate 4. become. Note that the support leg 7 is prevented from being removed by a bolt 12 screwed into a nut member 11 attached to the lower part of the support leg 7.

The panel holder 6 is formed into a substantially rectangular shape, and is provided with a support surface 13 on which the ends of four floor panels 2 having a structure described later are placed, and each floor panel 2 is placed on the support surface 13. A guide wall 14 and an engaging protrusion 15 corresponding to the above are formed. As shown in FIG. 5, the guide wall 14 has an angle that almost matches the inclination angle of the side wall 2a of the floor panel 2, and its upper end is bent in the horizontal direction. The function of guiding the floor panel 2 to a predetermined position when it is placed, and the side wall 2 of the placed floor panel 2.
It has a function of positioning by contacting a. Further, the engagement protrusion 15 is formed by burring, and engages with the engagement hole 16 of the floor panel 2 to restrict the horizontal movement of the floor panel 2 and the inclination of the support leg 7.

Moreover, the floor panel 2 is formed into a substantially square shape, and an upper surface panel 17 and a lower surface panel 18 are overlapped and integrated in a hollow shape, and an inorganic filler 19 such as mortar is sealed in the hollow portion. .

A step portion 2c with which the panel presser 9 is engaged is formed in the corner portion 2b.

Now, as shown in FIGS. 5 to 7, at the end of the floor panel 2, the upper panel 17 and the lower panel 1
A through hole 20 is formed across 8, and a holder 21 is embedded in this through hole 20 to form an engagement hole 16. The holder 21 is provided with a rib 22 and a pull-out stopper 23 on the outer peripheral surface, and a flange portion 25 at the periphery of the opening 24 at the lower end, while the opening side of the inner peripheral surface is formed in a tapered shape. has been done. In addition, the holder 21
Its dimensional accuracy is improved by resin injection molding. This holder 21 is attached to the through hole 20 before the filler is enclosed during floor panel molding, and the filler 19 that is later enclosed is firmly attached by fitting into the rib 22 and removal stopper 23 of the holder 21. ,
Burrings 26 and 27 formed at the peripheral edges of the upper panel 17 and lower panel 18 of the through hole 20 hold the upper and lower ends thereof and prevent deformation.

The engagement hole 16 having such a structure guides the engagement protrusion 15 of the panel holder 6 with its tapered portion when the floor panel 2 is placed, thereby facilitating the fitting operation. Note that by tightly fitting the engagement hole 16 and the engagement protrusion 15, horizontal movement and wobbling of the floor panel 2 are prevented. The interposition prevents metal-to-metal contact.

As shown in FIGS. 2 to 4, the above-described floor panels 2 are assembled and placed on the panel holder 6 in four pieces, and then the panel presser 9 is engaged with the panel presser holder 8. The stepped portion 2c of the corner portion 2b is tightened with one touch.

The panel retainer 8 is constructed by slidably inserting the retaining member 28 into the mounting bolt 30 via the collar 29, and further interposing a spring washer 31 between the head 30a of the mounting port 30 and the retaining member 28, so that the panel It is arranged at the center of the upper surface of the cradle 6.

That is, due to the spring force of the spring washer 31 that is compressed as the panel holder 9 is tightened, the floor panel 2 is pressed against the panel holder 9 with the part 25 of the flange 8 of the holder 21 on the bottom side in close contact with the support surface 13. It is firmly fixed between the panel holders 6.

At this time, the flange portion 25 of the holder 21 acts as a gasket.

Note that a slide ring 3 is provided between the panel presser 9 and the stepped portion 2c of the floor panel 2 in order to improve the slidability of the panel presser 9 and to absorb the difference in level between the stepped portions 2c of each floor panel.
2 is interposed therebetween, and a cap 33 is attached to the upper part of the panel retainer 9 for a finishing effect. In the figure, 34 indicates a carpet laid on the floor panel.

In this way, by placing and fixing the floor panel 2 on the panel holder 6, the floor panel 2 and the support legs 7 are brought into rigid contact to form an L-shaped rigid-frame structure, and this rigid-frame structure has a center of swing. It is supported on the pedestal board 4 via the cradle. When a horizontal load is applied to this structure due to an earthquake or the like, the center of swing will be at the contact point between the flange 5a of the adjustment nut 5 and the lower end of the support leg 7, which is extremely close to the pedestal base plate 4 (reference floor surface 10). Therefore, while a large bending moment acts on the upper end of the support leg 7, only a small bending moment acts on the pedestal board 4. That is, the pedestal substrate 4 does not need to be firmly fixed to the reference floor surface 10, and sufficient seismic performance can be obtained without increasing the adhesive strength.

(Effects of the Invention) As described above, according to the floor panel support structure of the present invention, a rigid frame structure is formed by the floor panel and the support legs, and the center of swing is the pedestal substrate (standard Because it is located close to the floor (floor surface), only a small bending moment acts on the pedestal board, the force that causes the pedestal board to separate from the reference floor surface is reduced, and it can have good seismic performance. .

Further, since the support leg is swingable with respect to the pedestal board using its lower end as a fulcrum, it is always vertically erected regardless of the levelness of the pedestal board.

Regarding the engagement between the floor panel and the support leg, first, during construction, the side wall of the floor panel is guided by the inclined guide wall formed on the panel holder at the top of the support leg, and
The tapered engagement hole of the floor panel allows the engagement protrusion of the panel holder to be inserted into the floor panel.
It can be easily placed in the correct position on the panel holder. In addition, the engagement hole in the floor panel that fits into the engagement protrusion of the panel holder is formed by embedding a resin holder and has high dimensional accuracy, which prevents horizontal movement of the floor panel and backlash. This can be prevented from occurring and can always be held in place.
