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 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, and the sufficient impact can be obtained. No absorption could be made.

In order to improve the elastic performance, the pedestal may be made of a material having a high elasticity. In this case, when a load is applied after the construction, the squat becomes large, and the walking feeling becomes poor. It becomes difficult to install furniture and so on stably.

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

Further, according to the prior art, since the impact on the floor is directly transmitted to the pedestal via the floor support, bolts, etc., it is not possible to obtain a sufficient soundproofing performance only by the elasticity of the pedestal. Was.

FIG. 1 shows an example of the construction of a floor panel supporting apparatus according to the present invention. The pedestal 1, a column 2 supported by the pedestal 1 in an upright state, a supporting plate 3, and a fixed member fixed to the supporting plate 3. And a receiving seat 4 which is attached and engages the upper end of the support 2.

The pedestal 1 is made 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 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.

On the upper surface of the pedestal 1, a fiber layer 20 is provided by fiber implantation. The fiber layer 20 can be formed by applying an adhesive to the upper surface of the pedestal 1 and then electrostatically implanting fibers.

Although not shown, a fiber layer formed by fiber implantation can be similarly provided on the bottom surface of the pedestal 1, or may be formed over the entire outer surface of the pedestal 1.

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 pedestal 1. Through hole 5
A flange 7 having a diameter sufficiently larger than the diameter of the flange 7 and a bolt 8 extending above the flange 7 are 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 pedestal 1 by inserting the lower round bar 6 into the non-through hole 5 of the pedestal 1. In addition, as shown in FIG.
The length of the round bar 6 at the lower end of the support 2 is set shorter than the depth of
As a result, when the lower round bar 6 is inserted,
A sealed air chamber is formed at the back end of the through hole 5. This
The air chamber acts as an air spring when impacted
In addition to the elastic deformation caused by the elasticity of the pedestal 1 itself,
Contributes to an even more effective shock absorption function
doing.

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.

The support plate 3 has a support 2 supported on the pedestal 1.
A through-hole 10 is formed at a position aligned with the bolt portion 8 of FIG. 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 16 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.

In the construction example shown in FIG. 1, the opposing ends of the adjoining floor panel 16 are placed and supported on the support plate 3.
It may be constructed so as to be placed and supported on top.

The floor panel support device as shown in the figure
It can be used by being fixed in advance at a plurality of predetermined positions on the back surface of a relatively large base plate having a predetermined size. in this case,
Through holes aligned with the through holes 10 in the support plate 3 are also formed in the base plate.

Further, the support plate 3 may have a large size and may be integrated with the base plate.

[0030]

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 shock absorption effect can be obtained without unnecessarily increasing the elasticity of the material of the pedestal itself, so that the feeling of walking caused by sinking of the floor surface due to the load after the construction and sagging due to the long-term load can be obtained. There is no problem such as the deterioration of the floor and the occurrence of irregularities in the level of the floor itself.

Since the fiber layer having an excellent cushioning effect is provided on the upper surface of the pedestal, the impact force from the floor is transmitted to the pedestal while being buffered, and the lower end of the support is inserted into the non-penetration.
When the sealed air chamber formed at the back end of the hole receives an impact
Since it works as an air spring, it exhibits an excellent soundproofing effect in combination with the elastic performance of the pedestal.
