[Detailed description of the invention]

[0001]

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. 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, the present invention provides a floor plate support in which an elastic pedestal installed on a floor base and a seat for directly or indirectly supporting a floor material are connected by a rotatable support column so that the height interval can be adjusted. In the apparatus, a contour wall is provided on a bottom surface of the elastic base.
And a concave portion surrounded by the contour wall.
A bottom surface, wherein the concave portion is filled with an elastic body having higher elasticity than the elastic pedestal.

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 material 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.

A concave portion 22 surrounded by a contour wall 21 is formed on the bottom surface of the elastic pedestal 1. In the illustrated embodiment, the recess 22 is formed in a ring shape. Further, the concave portion 22 has a rubber type,
An elastic body 23, which is an elastic body such as a foamed rubber, a synthetic resin, or a foamed synthetic resin, having higher elasticity than the elastic body forming the elastic base 1 is filled. With this configuration, the load
When receiving the weight, the protrusion on the bottom surface of the elastic pedestal 1
Elastic body 23 filled in the translucent wall 21 and the concave portion 22
Are contracted and deformed, and the cushioning of the impact force is more effectively performed in combination with the elasticity of the elastic base 1 itself.

[0013]

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

The support 2 has a lower round bar 6 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, and a lower round bar 6 formed above the round bar 6. 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.

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 a rectangular shape having 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 has a nut 11 at the lower end on which 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 is bonded and fixed to the through hole 10 of the support plate 3 using an adhesive. Alternatively, after the upper end cylindrical portion 13 is inserted into the through hole 10, the upper end cylindrical portion 13 may be fixed by caulking from the upper portion and widening the front end opening. Adhesion and fixing by swaging may be used in combination.

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.

As the floor panel 16 mounted on the support plate 3, a material such as a plywood (including LVL, LVB, etc.), a fiber board, a particle board, a wooden board, and a synthetic resin board is used. 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 affixing a discarded plywood with an adhesive, nails, or the like, and then bonding a desired floor material with an adhesive, nails, 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.

The floor can also be constructed by applying a floor coating material to the surface of the discarded plywood.

The upper end cylindrical portion 13 of the seat 4 is formed to have a larger diameter than the nut portion 11, and the bolt portion 8 of the support 2 is
A gap can be formed between the upper end cylindrical portion 13 and the bolt portion 8 in a state in which the upper end cylindrical portion 13 is screwed.

After the height of the support plate 3 and the floor panel 20 is adjusted, 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.

[0027]

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.

The desired impact absorbing effect can be obtained without unnecessarily increasing the elasticity of the material of the elastic pedestal itself. Therefore, walking caused by sinking of the floor surface due to the load after the construction or sagging by 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 contact area with the floor base, so that the propagation of the impact force to the floor base is reduced.
