[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 Such a floor plate supporting apparatus is generally disclosed in
As shown in JP-A-269254, an elastic pedestal such as rubber is attached to a lower end of a rod-shaped leg. A non-through hole is provided on the upper surface of the elastic base, and the lower end of the rod-shaped leg is inserted into the non-through hole to support the rod-shaped leg.

[0003] The floor panel support device having such a configuration absorbs and absorbs shocks by the elasticity of the pedestal, thereby improving vibration proofing and sound proofing.

[0004]

[Problems to be Solved by the Invention] The floor impact noise includes the sound of falling of a light object such as a spoon (lightweight hard impact source) and the sound of the falling of heavy objects such as children's jumping splash (weight soft impact source). There is. The above-mentioned conventional floor plate supporting device exhibits an effective buffering effect for a light and high impact source, but the supporting device jumps against a heavy and soft impact source, and the bar-shaped leg portion of the base plate is There was a case where it jumped out of the upper non-through hole. The falling off of the rod-shaped legs causes the floor surface to collapse, which is a very serious problem.

[0005] In the case of the floor plate supporting device having the above-described structure,
The effect of absorbing the impact on the floor mainly depends on the elastic performance of the elastic body itself of the pedestal, and it has been difficult to sufficiently absorb the impact. To improve the elastic performance, the pedestal may be made of a material with high elasticity, but in this case, the sinking becomes large when a load is applied after construction, the walking feeling becomes poor, and the furniture etc. Stable installation becomes difficult. Also,
There is a problem that the pedestal is set to a long-term load, and the level of the floor itself is deviated.

[0006]

[0009]

FIG. 1 shows an example of the construction of a floor panel supporting apparatus according to the present invention. An elastic pedestal 1 placed on a floor base 15, a column 2 supported by the elastic pedestal 1 in an upright state, and a support plate 3 and a support 2 fixedly attached to the support plate 3.
And a receiving seat 4 for engaging the upper end of the seat.

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. 30 to 30 for the elastic body forming the elastic base 1
A material having a hardness of 90 degrees is used. 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.

A non-through hole 5 is formed in the center of the upper surface of the elastic base 1. The overall shape of the elastic pedestal 1 is arbitrary,
The shape 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 column 2 is made of metal, synthetic resin, or the like. The column 2 has a lower round bar 6 having an outer diameter corresponding to the diameter of the non-through hole 5 formed in the upper surface of the elastic pedestal 1, and a non-through hole of the elastic pedestal 1 formed above the round bar 6. Collar 7 having a diameter sufficiently larger than the diameter of 5
And a bolt portion 8 extending above the collar portion 7 and having a concave groove 9 formed at the tip thereof are integrally formed. Prop 2
The lower end round bar 6 is rotatably supported relative to the elastic pedestal 1 by being inserted into the non-through hole 5 of the elastic pedestal 1.

The support plate 3 has a buffer sheet 17 interposed between base materials such as plywood (including LVL and LVB), fiberboard, particle board, wood board, and synthetic resin board. In the illustrated embodiment, one buffer sheet 17 is used.
Multiple layers may be interposed. As the buffer sheet 17,
Sheets such as synthetic resins, natural rubbers, synthetic rubbers, their foams, bituminous materials, and nonwoven fabrics can be used. Also,
When the buffer sheet is mixed with heavy metal powder, the sound insulation is improved.

The support plate 3 has a rectangular shape with a 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 portion 11 at the lower end where a female screw for screwing the bolt portion 8 of the column 2 is formed, and an enlarged diameter formed above the nut portion 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.

As the floor panel 16 mounted on the support plate 3, a material such as plywood (including LVL and LVB), fiber board, particle board, wood board, and 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 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. In addition, 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 formed to have a larger diameter than the nut portion 11, and the bolt portion 8 of the column 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 an 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 gap 14 is optional and not essential to the present invention.

In the illustrated embodiment, a ring-shaped member 20 is attached to the elastic pedestal 1. By providing the ring-shaped member 20, excessive horizontal deformation of the elastic pedestal 1 due to a load is prevented or suppressed. In particular, even when the elastic pedestal 1 is formed of an elastic body having a low hardness, it is possible to effectively prevent sinking when receiving a load or setting when receiving a long-term load.

The ring-shaped member is generally made of metal or synthetic resin, and its material, width and thickness dimensions are as follows.
It is arbitrarily selected and determined according to various conditions such as the hardness of the elastic pedestal 1 and the assumed load that varies depending on the place where the floor panel support device is used. Further, the ring-shaped member may be closely attached to the outer peripheral surface of the elastic pedestal 1 as in the illustrated embodiment, or may be provided with a slight gap between the elastic pedestal 1 and the elastic pedestal 1. The gap is
It is appropriately determined according to various conditions such as the hardness of the elastic pedestal 1 and the assumed load, but is preferably in the range of 0 to 5 mm.
For example, when the hardness of the elastic pedestal 1 is low, the initial sinking becomes large, so that the gap can be set small to prevent this, and the gap can be increased as the hardness increases.

Further, an upright cylindrical ring-shaped member may be attached to the elastic pedestal 1 having a substantially trapezoidal cross section. In this case, the lower end portion is in close contact with the outer surface of the elastic pedestal 1 with substantially no gap, but the gap increases toward the upper end portion. This is because deformation of the elastic pedestal due to load occurs from the upper part, so if the initial deformation is suppressed at the upper part of the elastic pedestal, it is impossible to maintain the shock buffering effect and the soundproofing effect for a long time. The upper gap is set to be large, and the lower gap is set to be small in order to suppress sinking.

A plurality of ring members may be provided. For example, a plurality of relatively narrow ring members can be attached to the elastic base 1 at intervals.

In the illustrated construction example, the opposite ends of the adjoining floor panel 16 are placed and supported on the support plate 3, but the center of the floor panel 16 is placed on the support plate 3. It may be constructed so as to be supported.

The floor panel supporting 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 be made large and integrated with the base plate.

[0031]

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, children jump on the floor
When subjected to the resulting soft / soft impact source,
A support plate with a thinner cushioning sheet interposed
The first stage of shock absorption is performed, after which the elastic pedestal
Because the second stage of shock absorption by elastic deformation is performed,
An effective buffering effect and soundproofing effect can be obtained.
