[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.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 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. 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.

[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 device, the elastic pedestal is
It has a through hole and a wide base at the bottom.
The pillar has a collar at a distance above the lower end.

FIG. 1 shows an example of the configuration of a floor panel support device according to the present invention. A pedestal 1 placed on a floor base 15 and this pedestal 1 are shown.
A support 2 supported in an upright state by the support plate 3,
The receiving plate 4 is fixedly attached to the support plate 3 and engages with the upper end of the column 2.

The 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 elastic body constituting the pedestal 1 has a hardness of 30 to 90 degrees. If the hardness is less than 30 degrees, the sinking under load is increased and the walking sensation is deteriorated, and the sag occurs under a long-term load and the restoring property is deteriorated. On the other hand, those having a hardness exceeding 90 degrees cannot obtain the desired impact buffering effect and soundproofing effect.

The shape of the pedestal 1 is arbitrary, and is not limited to the one having a substantially trapezoidal cross section as shown in the figure.

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 rotatable relative to the pedestal 1 by inserting the round bar 6 at the lower end thereof into the non-through hole 5 of the pedestal 1.
Supported. In addition, as shown in FIG.
Of the round bar 8 below the brim 7 of the column 2 than the depth of
Is set short, whereby the round bar 8 is inserted into the non-through hole 5.
In the closed state, a sealed air chamber is

As well as a shock absorbing function, and
The function of preventing this is as follows.
You.

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.

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, it may be fixed by caulking from the upper portion and widening the front end opening. Adhesion and fixing by swaging may be used together.

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), fiber board, 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 by attaching a discarded plywood with an adhesive or nail, a desired floor material is bonded with an adhesive or 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.

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 14 can be formed between the upper end cylindrical portion 13 and the bolt portion 8 in the state where the screw portion 1 is screwed.

After the height of the support plate 3 and the floor panel 16 is adjusted, a room temperature-curable resin or adhesive (including a foaming adhesive and a foaming adhesive) is injected into the space 14. . 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.

The formation of the space 14 is optional and not essential to the present invention.

According to the present invention, a cap-like member for preventing horizontal and vertical deformation of the pedestal 1 is attached to the pedestal 1 in the floor panel supporting apparatus having the above-described configuration. In the first embodiment, the cap-shaped member 20 is attached to the outer surface of the pedestal 1 so as to be tightly contacted with no gap. In addition, as is clear from the state shown in the drawing.
In addition, the lower end of the cap-shaped member 20 is above the wide lower portion of the base 1.
Floor base 1 even when receiving a load from above.
5 is not contacted.

By providing the cap-like member 20,
The deformation of the pedestal 1 in the horizontal and vertical directions due to the load is prevented. In particular, even when the pedestal 1 is formed of an elastic body having a low hardness, it is possible to effectively prevent sinking when receiving a load and setting when receiving a long-term load.

The cap-shaped member is generally made of metal or synthetic resin. The material, width and thickness of the cap-shaped member vary depending on the hardness of the pedestal 1 and the assumed load that varies depending on the place where the floor plate supporting device is used. It is arbitrarily selected and determined according to conditions.

FIGS. 2 and 3 show another example of the structure of the pedestal 1 used in the floor panel support device of the present invention, particularly showing a modification of the cap-like member.

In the modification shown in FIG. 2, a cap-like member 21 similar to that shown in FIG. The gap is appropriately determined depending on various conditions such as the hardness of the pedestal 1 and the assumed load, but is preferably in the range of 0 to 5 mm.

For example, when the hardness of the pedestal 1 is low, the initial sinking becomes large. Therefore, to prevent this, the gap is set small, and as the hardness increases, the gap can be increased.

In the modification shown in FIG. 3, a cap-like member 22 having an upright peripheral wall surface is attached to a pedestal 1 having a substantially trapezoidal cross section, and the outer surface of the pedestal 1 has substantially no gap at its lower end. , But the gap increases toward the upper end. This is because the deformation of the pedestal due to the load occurs from the upper part, so if the initial deformation is suppressed at the upper part of the pedestal, the shock buffering effect and the soundproofing effect cannot be maintained for a long time, The upper gap is set large, and the lower gap is set small to suppress sinking.

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, but the central portion of the floor panel 16 is supported by the support plate. 3 and may be constructed so as to be placed and supported on it.

The floor panel supporting device as shown in the figure is
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 be made large in size and integrated with the base plate.

[0038]

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

In particular, even when the pedestal is formed of an elastic body having a small hardness in order to enhance the shock absorbing effect and the soundproofing effect, the pedestal is effectively deformed in the horizontal and vertical directions by the action of the cap-shaped member. Since this is prevented, problems such as sinking of the floor surface due to the load after construction, deterioration of walking feeling due to settling due to long-term load, and occurrence of irregularities in the level of the floor itself do not occur.
