Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor plate supporting device used for a floor for constructing floor plates on a floor of an apartment house, an office or the like with a predetermined interval.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a floor board supporting device is generally provided with a collar portion 4a at the bottom of a column 4, and a protrusion 4b formed at the bottom portion of the collar portion is provided with a surface of a base A formed of rubber or the like. The pedestal is connected by being fitted in the concave portion formed on the floor base 11, and is mounted on the floor base 11.

[0003]

Recently, even a floor composed of such a floor board supporting device is required to have soundproofing performance, but the hardness of rubber and the thickness of rubber of the pedestal are changed. Even if it was done, the soundproofing performance obtained was not sufficiently satisfactory, and conversely, there was a problem that the walking feeling when walking on the finished floor became poor.

[0004]

SUMMARY OF THE INVENTION The present invention has been completed as a result of intensive studies in order to provide a floor having excellent soundproofing performance and a good walking feeling in view of the above problems. It is a thing. That is, according to the present invention, a floor board supporting device in which a pedestal placed on a floor base 11 and a pedestal for directly or indirectly supporting a floor base material are connected by a column 4 capable of relative rotation in a height-adjustable manner. In the above, the floor board support device is characterized in that the pedestal connected to the lower part of the support column 4 is a laminated body of the pedestal substrate 1 and the cushioning material 2 laminated on the bottom surface thereof.

In the floor board supporting apparatus of the present invention, the pedestal connected to the lower portion of the support column 4 is composed of a laminated body of a pedestal substrate 1 having a bottom area of 20 cm ² or more and a cushioning material 2 laminated on the bottom surface thereof. Although the impact applied to the surface of the floor plate is transmitted to the pedestal through the struts 4, since the pedestal substrate 1 having a bottom area of 20 cm ² or more is formed on the surface side of the pedestal, the pedestal substrate 1 is evenly distributed over the entire pedestal substrate 1. Then, the shock absorbing effect is absorbed by the entire cushioning material 2 laminated on the back surface of the cushioning material 2 to provide excellent soundproofing performance.

[0006]

1 shows a structural example of a floor board supporting apparatus of the present invention, in which a pedestal composed of a pedestal substrate 1 and a cushioning material 2 laminated on the back surface thereof is placed on a floor base 11. Is
A support column 4 supported in an upright state by a support column 3 fixed to the surface of the pedestal substrate 1, a support plate 6, and a top end of the support column 4 fixedly attached to the support plate 6. It is composed of a seat 5.

The pedestal substrate 1 may be a plywood, a wood fiber plate, a wood slab, a wood plate such as a single laminated plate, a metal plate or a synthetic resin plate. The pedestal substrate may have a circular or square planar shape. , Pentagon and other polygons can be used without particular limitation, and the bottom area is 20c.
Use m ² or more. If the pedestal substrate 1 having a bottom area of less than 20 cm ² is used, the impact applied to the floorboard surface is locally transmitted to the floor base without being diffused, resulting in poor soundproofing performance. Also, the base board 1
It is preferable to use a material having an arbitrary thickness such that the Young's modulus of bending is 5000 Kg / cm ² or more.

The Young's modulus of bending of the base substrate 1 is 5000 Kg
If less than / cm ² is used, when the impact applied to the floor board surface is transmitted to the base substrate 1 through the support columns 4, the base substrate 1 itself is easily bent and deformed, and the entire base substrate 1 is impacted. Since the shock cannot be dispersed and the shock is concentrated and transmitted to a part of the cushioning material 2 on the back surface side, the shock absorbing material 2 cannot absorb the shock and sufficient soundproof performance cannot be obtained.

In the configuration shown in FIG. 1, the column support portion 3
Is made of metal or synthetic resin, and has a through-hole or a non-through-hole for fitting the support column 4 in the center thereof and is fixed to the base substrate 1. In addition, FIG. 2 shows another embodiment, and it is also possible to use one in which the support column 3 is integrally molded with the pedestal substrate 1 with a synthetic resin or the like.

Further, as shown in FIG. 3, a pillar 4a is formed at the lower end of the pillar 4 without forming a pillar supporting portion, and a round bar 4b protruding further downward from the collar 4a is used. The support rod 4 may be supported in an upright state by fitting the round bar 4b into the opening 1b formed in the substantially central portion on the front surface side of the base substrate 1.

As the cushioning material 2, a synthetic resin sheet of polyethylene resin, polypropylene resin, polyurethane resin, polystyrene resin and the like, and a foam sheet thereof, a rubber foam sheet, a cushion sheet such as a non-woven fabric, can be used. Preferably, the static spring constant is 0.1 to 25 Kg / c
Use those in the range of m ² . When using foam,
Even if the foam sheet has the same expansion ratio, the hardness of the foam sheet naturally differs due to the different resin.

The static spring constant of this foamed sheet affects the cushioning function as a cushioning material and the amount of sinking when a load is applied to the floor plate surface. If it is less than 0.1 Kg / cm ² , the cushioning function is obtained. Is excellent, but since it is soft, the amount of sinking is large, which causes problems such as poor walking feeling. On the other hand, if it is more than 25 kg / cm ^2, it is not preferable because it is too hard to perform a sufficient buffering function.

The pillar 4 is made of metal or synthetic resin. When the column 4 is supported by the column support 3 as shown in FIGS. 1 and 2, the column 4 has a lower end round bar 4d having an outer diameter corresponding to the diameter of the opening of the column support 3, Accordingly, a female screw is formed on the inner surface of the opening of the support column 3,
It is also possible to use one in which a bolt portion that can be screwed into this female screw is formed on the pillar lower end round bar 4d. In this way, screws are respectively formed on the inner surface of the opening of the column support 3 and the column lower end rod 4d of the column, and by being screwed together, the pedestal substrate 1 is supported rotatably.

By rotating the support, the height from the support support to the support plate 6 can be adjusted. Further, as shown in FIG. 3, an opening is provided in the substantially central portion of the surface of the pedestal substrate 1, and when the pillar 4 is inserted into this opening,
A round bar 4b having an outer diameter corresponding to the diameter of the opening, and a collar portion 4a formed on the upper part of the round bar 4b and having a diameter sufficiently larger than the diameter of the opening provided in the base substrate 1.
Is used.

By using such a pillar 4, the lower end round bar 1b of the pillar 4 is inserted into the opening of the pedestal surface, and the flange portion 4a is in contact with the surface of the pedestal substrate 1, with respect to the pedestal substrate 1. It is supported for relative rotation. Further, a bolt portion 4c is formed continuously from the lower end of the support to the upper end, or from an arbitrary position to the upper end, and a groove is formed on the tip surface of the upper end.

As the support plate 6, plywood (LVL, LVB)
Etc.), fiber board, particle board, wood board, synthetic resin board, and the like, and each side has a square shape of 5 to 20 cm and an arbitrary thickness. If one side is set to 5 to 20 cm, if it is smaller than this, the holding area of the flooring panel 7 constructed on the support plate 3 becomes insufficient, and if it is larger than this, it causes an increase in weight and becomes difficult to handle. This is because.

Through holes 10 are formed in the support plate 6 at positions aligned with the bolt portions 4c of the support columns 4 supported by the pedestal. The through hole 10 has a diameter sufficiently larger than the bolt diameter. On the surface of the support plate 3, an adhesive layer (not shown) surface-coated with a release paper (not shown) can be laminated and formed in order to facilitate the construction of the floor placement panel 7.

The receiving seat 5 made of metal or synthetic resin is formed with a nut portion 5a at the lower end on which a female screw for screwing the bolt portion of the column 4 is engraved, and an enlarged diameter above the nut portion 5a. Through the through hole 1 of the support plate 6 above the receiving collar 5b.
It is formed integrally with the cylindrical portion 5c at the upper end that is fitted into the inside of 0. The upper end tubular portion 5c is adhesively fixed to the through hole 10 of the support plate 6 using an adhesive. Alternatively, after the upper end tubular portion 5c is inserted into the through hole 10, the upper end tubular portion 5c may be caulked from the upper portion and the tip end opening may be widened to fix the same.

At least the nut portion 5a at the lower end is internally provided with a female screw for screwing the bolt portion of the column 4.
The upper end tubular portion 5c has a hole 5 opened on the upper surface of the floor material support device.
d is formed. The upper end tubular portion 5d of the seat 5 is attached to the nut portion 5
It is possible to form a gap between the upper end tubular portion 5d and the bolt portion 4c when the bolt portion 4c of the support column 4 is screwed into the nut portion 5a by forming the bolt portion 4c with a diameter larger than a. The height of the receiving seat 5 from the pedestal can be adjusted by rotating the concave groove formed on the front end surface of the column in the gap with a driver.

At this time, by forming a screw that can be screwed into the inner surface of the opening of the supporting column 4d and the round bar 4d at the lower end of the supporting column, the amount of change in height caused by rotating the supporting column 4 with a driver can be reduced. It can be doubled.

Materials such as plywood (including LVL, LVB, etc.), fiber board, particle board, wood board, synthetic resin board and the like are used for the floor placement panel 7 to be placed on the support board 6. The size of the flooring panel 7 is preferably small for easy carrying and good workability. However, if it is too small, the number of sheets required for construction will increase and the construction will be troublesome.

If the length dimension is too large with respect to the width dimension, when the load is applied, the bending in the longitudinal direction easily occurs. For these reasons, flooring panels are 30-75 cm wide and 90-300 cm long.
The width is preferably 45 cm to 7
5 cm × length 180 to 240 cm.

After laying the flooring panel 7 in the whole room,
A floor-laying structure is obtained by directly or after discarding a plywood laminated with an adhesive, nails or the like, and then fixing a desired floor material with the adhesive, nails or the like. Examples of the floor material include a wooden floor, a wooden floor with a cushioning material attached to the back surface, a rug such as a carpet, a floor tile, and a tatami mat. The floor can also be constructed by applying a floor coating material to the surface of the throw-up plywood.

[0024]

According to the floor board supporting device of the present invention, the pedestal connected to the lower portion of the column 4 is composed of a laminated body of the pedestal substrate 1 having a bottom area of 20 cm ² or more and the cushioning material 2 laminated on the bottom surface thereof. It is possible to provide a floor board supporting device having excellent soundproofing performance without deteriorating the feeling of walking. Furthermore, compared to the conventional rubber pedestal, the center of gravity becomes lower and problems such as the floor support device falling over during construction are less likely to occur,
The workability is also good.
