BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor board support device used for a floor-standing structure for constructing floor boards at predetermined intervals on the floor of an apartment house or office.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Publication No. 54-3542
A method of constructing a floor using a floor panel support device having a configuration as described in Japanese Patent Application Laid-Open Publication No. H10-209,878 is employed. This floorboard support device,
A play hole is provided in at least each corner of the square floor support material, and a bolt is screwed or fitted into the play hole.On the other hand, the lower end of the bolt is mounted on a pedestal placed in a proper place on a floor base such as mortar. It is configured to be screwed and supported in an upright state.

[0003] In this way, the floor support members are sequentially attached and spread, and the height of the floor support members is adjusted by inserting a screwdriver from above the play hole and rotating the bolt, and then the floor support members are spread. By placing a desired floor finishing material on the floor support material, the floor is constructed.

[0004]

Since the elastic pedestal in the above-mentioned conventional floor plate supporting device has a flat bottom surface, the absorbing effect on the impact on the floor solely depends on the elastic performance of the elastic body itself of the pedestal. Could not absorb shock.

In order to improve the elastic performance, the pedestal may be made of a material having high elasticity. In this case, when a load is applied after the construction, the squat becomes large and the walking feeling becomes poor. I will.

In addition, there is a problem that the elastic pedestal is set against a long-term load, and the level of the floor itself is deviated.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a novel floor panel supporting apparatus which can solve the above-mentioned disadvantages of the prior art.

That is, according to the present invention, an elastic pedestal installed on a floor base and a receiving seat having at least an upper cylindrical portion and a nut portion for directly or indirectly supporting a floor material are screwed into the nut portion. In a floor plate supporting device which is connected so that a height interval can be adjusted by a support having a bolt portion on the upper side, a bottom surface of the elastic base is formed in an uneven shape, and a non-through hole formed from an upper surface side of the elastic base. The lower end of the support is inserted into the lower end of the support, the dimension of the lower end insertion portion of the support is shorter than the depth of the non-through hole, and a sealed air chamber is formed at the back end of the non-through hole. Since the upper end cylindrical portion is formed to have a larger diameter than the nut portion, a gap is formed between the upper end cylindrical portion of the seat and the bolt portion of the post, and the gap is formed after adjusting the height of the seat. The seat and the bolt part are filled with resin or adhesive and cured. The outer diameter of the upper end cylindrical portion is formed to be equal over the entire length in the height direction, and an adhesive is applied to the outer peripheral surface to fix the support plate, thereby fixing the floor. It is characterized by supporting materials directly or indirectly.

FIG. 1 shows an example of the structure of a floor plate supporting apparatus according to the present invention. An elastic pedestal 1, a supporting column 2 supported by the elastic pedestal 1 in an upright state, a supporting plate 3, and a fixing member fixed to the supporting plate 3. Seat 4 which is fixedly attached and engages the upper end of the column 2
It is composed of

The elastic pedestal 1 is formed of an elastic body such as a rubber, a foamed rubber, a synthetic resin, and a foamed synthetic resin, and absorbs and absorbs an impact force. The shape of the elastic pedestal 1 is arbitrary, and is not limited to the illustrated one having a substantially trapezoidal cross section, and may be, for example, a rectangular shape or a square shape.

The bottom surface of the elastic pedestal 1 has a concave portion 21 and a convex portion 22.
Are formed in an uneven shape. For example, the bottom surface is regularly cut in a grid pattern, a diamond shape or the like to form the concave portion 21,
Alternatively, the concave portions 21 are randomly formed, and the remaining portions are formed as the convex portions 22.
As a concave and convex bottom surface. Since the elastic pedestal 1 has an uneven bottom surface as described above, the convex portion 22 is flattened and compressed when a load is received. Done more effectively.

The column 2 is made of metal, synthetic resin, or the like.

The column 2 has a round bar 6 at the lower end having an outer diameter corresponding to the diameter of the non-through hole 5 formed at the center of the upper surface of the elastic pedestal 1. A collar portion 7 having a diameter sufficiently larger than the diameter of the non-through hole 5;
A bolt portion 8 extending above the flange portion 7 is integrally formed. A concave groove 9 is formed at the tip of the bolt portion 8. The column 2 is rotatably supported relative to the elastic base 1 by inserting the lower round bar 6 into the non-through hole 5 of the base 1. In addition, as shown in FIG.
The length of the round bar 6 at the lower end of the column 2 is shorter than the depth of the through hole 5.
Is set, so that the lower round bar 6 is inserted.
And a sealed air chamber is formed at the back end of the non-through hole 5.
You. This air chamber is equipped with an air spring

More efficient shock absorption in addition to the uneven bottom surface
It contributes to exhibiting a profit function.

As the support plate 3, plywood (LVL, LVB)
Etc.), a fiber board, a particle board, a wood board, a synthetic resin board, or the like, and has a rectangular shape with one side of 5 to 20 cm and an arbitrary thickness. When the side is 5 to 20 cm, if it is smaller than this, the holding area of the floor panel 16 to be constructed on the support plate 3 becomes insufficient, and if it is larger than this, the weight increases and it becomes difficult to handle. That's why.

A through hole 10 is formed in the support plate 3 at a position aligned with the bolt 8 of the column 2 supported by the elastic pedestal 1. This through hole 10 has a diameter sufficiently larger than the bolt diameter.

An adhesive layer (not shown) coated on a release paper (not shown) is formed on the surface of the support plate 3 to facilitate the installation of the floor panel 16. Can be.

The metal or synthetic resin seat 4 is provided with a nut 11 at the lower end where a female screw for screwing the bolt 8 of the column 2 is formed, and an enlarged diameter formed above the nut 11. And a cylindrical portion 1 at an upper end above the receiving flange 12 and fitted into the through hole 10 of the support plate 3.
3 are integrally formed. The upper end cylindrical portion 13 has the same outer diameter over the entire length in the height direction, and is fixed to the through hole 10 of the support plate 3 by using an adhesive.

A female screw for screwing the bolt 8 of the column 2 is formed in the nut 11 at least at the lower end, and a hole 14 opening to the upper surface of the flooring support device is formed in the upper cylindrical portion 13. Provided.

The floor panel 16 mounted on the support plate 3 is made of a material such as plywood (including LVL and LVB), fiberboard, particle board, wood board, and synthetic resin board. The size of the floor panel is preferably small in order to make it easy to carry and improve the workability. However, if the size is too small, the number of sheets required for the work increases and the work is rather troublesome. Further, if the length is too large relative to the width, bending in the longitudinal direction is likely to occur when a load is applied.
For these reasons, the floor panel has a width of 30 to 75 c.
mx 90 to 300 cm in length, preferably 45 to 75 cm in width x 180 to 240 cm in length
And

After laying the floor panel 16 over the entire room, directly or on a discarded plywood with an adhesive or a nail or the like, a desired floor material is bonded with an adhesive or a nail or the like. By fixing, a floor-standing structure is obtained.

Examples of the floor material include a wooden floor, a wooden floor having a cushioning material adhered to the back surface, a rug such as a carpet, a floor tile, a tatami mat and the like.

Further, a floor can be formed by applying a floor coating material to the surface of the discarded plywood.

The upper end cylindrical portion 13 of the seat 4 is
And the bolt 8 of the column 2 is
The upper end cylindrical portion 13 is screwed into the
A gap 23 is formed between the bolt and the bolt portion 8.

After adjusting the heights of the support plate 3 and the floor panel 20, a room temperature-curable resin or an adhesive (including a foaming adhesive and a foaming adhesive) is injected into the space. The injected resin is filled into the voids, and part of the resin penetrates into the nut portion 11. As the injected resin hardens, the bolt portion 8 is completely fixed to the receiving seat 4, and an additional effect that the support plate 3 is fixedly held at a predetermined height position is obtained.

[0025]

According to the present invention, it is possible to provide a floor panel supporting apparatus which is excellent in a shock absorbing and absorbing effect against an impact force from a floor surface in a floor placing structure.

Since the desired impact absorbing effect can be obtained without unnecessarily increasing the elasticity of the material of the elastic pedestal, the walking caused by the sinking of the floor surface due to the load after construction and the settling due to the long-term load can be obtained. There is no problem such as deterioration of feeling and occurrence of irregularities in the level of the floor itself.

The formation of the concave portion on the bottom surface of the elastic pedestal reduces the installation area with the floor base, so that the propagation of the impact force to the floor base is reduced. In addition, the upper cylindrical part of the
The resin or adhesive injected into the gap between the
The seat is completely fixed to the bolt
Thus, the support plate is fixedly held at a predetermined height position.
