Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel support leg for a double floor.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional example in which a double floor is constructed by a plurality of floor panels 3, 3. In this conventional example, the panel support leg 4 supporting the floor panel 3
Is provided with a support rod 7 standing on the floor base 1, and a support arm 10 attached to the upper end of the support rod 7. The support arm 10 has a screw hole 11 at a free end thereof, and the floor panel 3 having four corners mounted on the arm portion 10 a is fixed by a screw 12 screwed into the screw hole 11.

[0003]

However, in the above-described conventional example, the structure is such that the load on the floor panel 3 is received by the arm portion 10a of the support arm 10 which cantilevers from the panel support leg 4. In addition, when installing a heavy load device or the like on the double floor, it is necessary to make the arm portion 10a strong. Therefore, the support arm 1
0 is required to have a cross-sectional shape with a large cross-section coefficient or to use a high-strength material so as to have sufficient strength against the bending moment and shearing force generated, and the supporting rod 7 In addition, since a bending moment is generated, the supporting arm 10 and the supporting rod portion 7 have a drawback that they become a factor of cost increase in consideration of material cost or molding workability.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a panel support leg for a double floor which is inexpensive and has sufficient holding strength.

[0005]

According to the present invention, the above object is achieved by a panel supporting surface 2 which is erected on a floor base 1 and is formed at the upper end, as shown in FIG. 1 corresponding to an embodiment. A panel support leg in a double floor that supports an abutting corner portion of a panel 3, wherein the panel support surface 2 is formed in a shape that is substantially congruent with the cross-sectional shape of the general portion, and the panel support surface 2 has Positioning holes 5 provided in the floor panel 3
It is achieved by providing a panel support leg in a double floor provided with a protrusion 6 for preventing the floor panel 3 from being detached from the panel support surface 2.

[0006]

In the present invention, the floor panel 3 is installed with the abutting four corners supported by the panel supporting surface 2 formed at the upper end of the panel supporting leg 4, and the load on the double floor is determined by the floor panel 3. The load is applied to the panel support surface 2 of the panel support leg 4 through.

FIGS. 6 (a) and 6 (b) show a state in which a load is applied to the panel support leg 4 according to the present invention and the panel support leg 4'according to the conventional example. In the conventional example, the support arm is shown. Since the structure 10 projects laterally from the support rod 7, the base end of the support arm 10 and the support rod 7
A bending moment M is generated at the base end of the support rod 7, and a compressive load P is applied to the support rod 7.

On the other hand, in the present invention, the panel support surface 2 has substantially the same shape as the general sectional shape of the panel support leg 4, and the load on the floor panel 3 is applied to the upper end of the panel support leg 4. It acts only as the applied stigma load P, and no bending moment is generated on the support rod 7.

In the rod-shaped structure, the strength compensation for the bending moment is a larger factor than the buckling deformation due to the compressive load, but it is possible to reduce the occurrence of the bending moment as much as possible. In the panel support leg of the invention, it is possible to perform strength design considering only buckling deformation, and it is possible to reduce material selection, usage amount, and the like.

The projections 6 prevent the floor panel 3 from being easily detached from the panel support surface 2 because the bearing surface of the floor panel 3 is reduced. Further, in the invention according to claim 2, the projections 6 are arranged with their centers centered on the peripheral edge of the panel support surface 2.
By increasing the effective area of the above as much as possible and reinforcing the protrusions 6 with the bulging portions 9, sufficient shear strength is exhibited even when a lateral load is applied to the floor surface.

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. Panel support leg 4 according to the present invention
1 and 2 show a state in which the floor panel 3 is supported by using. The panel support legs 4 are erected at a predetermined pitch by adhering the base plate 13 fixed to the lower ends to the floor base 1, and the four corners are supported by the panel support surface 2 formed at the upper ends of the panel support legs 4. Floor panels 3, 3
・ Will be installed. Further, in order to prevent the floor panel 3 from falling off from the panel support surface 2 when a lateral load is applied to the double floor surface, the panel support surface 2 has a protrusion that fits into the positioning hole 5 of the floor panel 3. 6 is provided.

The panel support leg 4 in this embodiment is fixed on the base plate 13 and is mounted on the support rod 7 having a screw rod 14 protruding from the upper end thereof, and the screw rod 14 of the support rod 7, and the upper end thereof is mounted on the panel. The panel receiving member 8 serving as the support surface 2 is provided, and an adjusting nut 15 for adjusting the installation height of the panel receiving member 8 is screwed into the screw rod 14.
In FIG. 3, 16 is a bolt for preventing the adjustment nut 15 from being displaced and loosened, and 22 is a packing for preventing an interference sound with the floor panel 3.

The panel receiving member 8 is a cylindrical member made of aluminum die casting, and is mounted in a state in which the screw rod 14 is capped and the lower end edge thereof is placed on the adjusting nut 15. A bolt 17 is screwed into the cylindrical portion 8a of the panel receiving member 8 to prevent the screw rod 14 from rotating.

Further, a screw hole 18 is formed in the central portion of the panel supporting surface 2, and as shown in FIG. 4, a stopper for attaching a cap 19 to the abutting corner of the floor panel 3. It offers 20 trays. In this way, the corner notch 21 formed in the floor panel 3'of the specification in which the cap 19 is attached to the abutting corner is fitted into the molding die of the floor panel 3 of the specification shown in FIG. The floor panels 3 and 3'are manufactured by detaching the nests.

On the other hand, four protrusions 6 are formed at equal intervals centered on the peripheral edge of the panel support surface 2,
Consideration is made so that the panel support surface 2 is as wide as possible.
The projection 6 is provided to prevent the floor panel 3 from falling off the panel support surface 2 and to guide the mounting position of the floor panel 3, but when a lateral load is applied to the floor surface. In order to prevent breakage of the protrusion, the protruding portion of the protrusion 6 from the panel supporting surface 2 to the outside and the tubular portion 8a are
Joined by the bulge 9.

[0016]

As is apparent from the above description, according to the panel support leg in the double floor of the present invention, the bending moment is not applied by the load on the floor surface, so that the strength condition can be relaxed. For this reason, the manufacturing method or the selection criteria of the used material is loosened, and the manufacturing cost can be reduced.

Further, since the panel supporting surface 2 becomes small,
As shown in FIGS. 6C and 6D, the panel support leg 4,
Even when the entire 4'is bent, the difference in height between both end edges of the panel support surface 2 is reduced, and the step d between the floor panels 3 can be reduced. It should be noted that FIG. 6C shows the panel support leg in the present invention, and FIG. 6D shows the panel support leg in the conventional example.
