[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor plate supporting device used for a floor structure for constructing floor plates on a floor of an apartment house, an office, or the like at predetermined intervals.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a method of constructing a floor using a floor board supporting device having a structure as described in Japanese Utility Model Publication No. 54-3542 is adopted. This floor board support device is provided with play holes at least at each corner of a rectangular floor support, and bolts are screwed or fitted into the play holes.On the other hand, on a pedestal placed in a proper place on the floor base such as mortar. The lower end of this bolt is screwed and supported in an upright state.

In this way, the floor supports are sequentially attached and spread, and the height of the floor supports is adjusted by inserting a screwdriver from above the play hole and rotating the bolt, and then the floor supports are spread. By placing a desired floor finishing material on the above-mentioned floor support material, the floor is constructed.

[0004]

[Problems to be solved by the device]

 Since the pedestal in the above-mentioned conventional floor board supporting device has a flat bottom surface, the absorbing action for the impact on the floor depends only on the elastic performance of the elastic body of the pedestal itself, and cannot sufficiently absorb the impact.

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

Further, there is a problem in that the pedestal becomes depressed due to a long-term load, and the floor itself is distorted.

[0007]

[Means for Solving the Problems]

 Therefore, an object of the present invention is to provide a novel floor board supporting device capable of solving the above-mentioned drawbacks of the prior art.

That is, according to the present invention, a floor board support in which a pedestal installed on a floor base and a pedestal for directly or indirectly supporting a floor material are connected by a relatively rotatable column so that height intervals can be adjusted. The device is characterized in that a cap-shaped member for preventing deformation of the elastic pedestal in the horizontal direction and the vertical direction is attached to the elastic pedestal.

Preferably, a gap of 0 to 5 mm is arranged between the outer surface of the elastic pedestal and the inner surface of the cap-shaped member.

[0010]

[Action]

 A cap-shaped member attached around the elastic pedestal prevents horizontal and vertical deformation of the pedestal when subjected to a load.

【Example】

 FIG. 1 shows an example of the construction of a floor board supporting device according to the present invention. A pedestal 1 placed on a floor base 15, a column 2 supported by the pedestal 1 in an upright state, a support plate 3, and the support thereof. It is composed of a seat 4 which is fixedly attached to the plate 3 and engages the upper end portion of the column 2.

The pedestal 1 is formed of an elastic body such as a rubber type, a foam rubber type, a synthetic resin type, or a foam synthetic resin type, and cushions and absorbs impact force. The elastic body forming the base 1 has a hardness of 30 to 90 degrees. If the hardness is less than 30 degrees, the subsidence when a load is applied becomes large and the walking feeling deteriorates, and when the load is applied for a long period of time, it becomes depressed and the restorability deteriorates. On the other hand, if the hardness exceeds 90 degrees, the desired shock absorbing effect and soundproofing effect cannot be obtained.

The shape of the pedestal 1 is arbitrary and is not limited to the substantially trapezoidal cross section shown in the figure, and may be, for example, a rectangular shape or a square shape.

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

The pillar 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 in the central portion of the upper surface of the pedestal 1, and a non-circular shape of the pedestal 1 formed above the round bar 6. A brim portion 7 having a diameter sufficiently larger than the diameter of the through hole 5 and a bolt portion 8 extending above the brim portion 7 are integrally formed. A groove 9 is formed at the tip of the bolt portion 8. The support rod 2 is instructed to be rotatable relative to the pedestal 1 by inserting the lower end round bar 6 into the non-through hole 5 of the pedestal 1.

The support plate 3 is made of a material such as plywood (including LVL, LVB, etc.), fiber board, particle board, wood board, synthetic resin board, etc., and has a rectangular shape with a side of 5 to 20 cm and an arbitrary thickness. It is said that If the width is smaller than 5 to 20 cm, the holding area of the floor panel 16 constructed on the support plate 3 becomes insufficient, and if it is larger than this, the weight is increased and it becomes difficult to handle. This is because it will end up.

A through hole 10 is formed in the support plate 3 at a position aligned with the bolt portion 8 of the support column 2 supported by the pedestal 1. The through hole 10 has a diameter sufficiently larger than the bolt diameter.

On the surface of the support plate 3, in order to facilitate the construction of the flooring panel 16, an adhesive layer (not shown) coated with a release paper (not shown) is laminated. You can

The metal-made or synthetic-resin seat 4 has a lower end nut portion 11 on which a female screw for screwing a bolt portion 8 of the support column 2 is engraved, and an enlarged diameter is formed above the nut portion 11. The receiving brim portion 12 and the tubular portion 13 at the upper end, which is above the receiving brim portion 12 and is fitted into the through hole 10 of the support plate 3, are integrally formed. The upper end tubular portion 13 is adhesively fixed to the through hole 10 of the support plate 3 using an adhesive. Alternatively, after the upper end tubular portion 13 is inserted into the through hole 10, the upper end tubular portion 13 may be caulked from the upper portion and the distal end opening may be widened to be fixed. Adhesion and fixing by caulking may be used together.

At least the nut portion 11 at the lower end is internally engraved with a female screw into which the bolt portion 8 of the support column 2 is screwed, and the upper end tubular portion 13 has a hole 14 that opens to the upper surface of the floor material support device. Is provided.

As the floor placement panel 16 placed and installed on the support plate 3, materials such as plywood (including LVL, LV B, etc.), fiber board, particle board, wood board, synthetic resin board and the like are used. The size of this floor panel is preferably small in order to make it easy to carry and to improve the workability, but on the other hand, if it is too small, the number of sheets required for construction increases and the construction becomes rather troublesome. If the length dimension is too large with respect to the width dimension, bending in the longitudinal direction tends to occur when a load is applied. For these reasons, the flooring panel preferably has a width of 30 to 75 cm and a length of 90 to 300 cm, more preferably a width of 45 to 75 cm and a length of 180 to 240 cm.

After laying the flooring panel 16 in the whole room, directly or after fixing the throwing plywood with the adhesive or the nail, the desired flooring material is used with the adhesive or the nail. A fixed floor structure can be obtained by sticking together.

Examples of the floor material include a wooden floor, a wooden floor having a cushioning material attached to the back surface, a rug such as a carpet, a floor tile, a tatami mat, and the like.

Further, the floor can be constructed by applying a floor coating material on the surface of the discarded laminated board.

When the upper end tubular 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 screwed into the nut portion 11, the upper end tubular portion 13 and the bolt An air gap 14 can be formed between the portion 8 and.

After adjusting the heights of the support plate 3 and the floor placement panel 16, a room temperature curable resin or adhesive (including a foaming adhesive and a foaming adhesive) is injected into the void 14. . The injected resin fills the voids and partly penetrates into the nut portion 11. By hardening the injected resin, the bolt portion 8 is completely fixed to the seat 4, and the additional effect that the support plate 3 is fixedly held at a predetermined height position is obtained.

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

According to the present invention, in the floor board supporting device having the above-mentioned structure, the pedestal 1 is covered with a cap-shaped member for preventing its horizontal and vertical deformation. In the embodiment of FIG. 1, it is shown as a cap-shaped member 20 that is adhered to the outer surface of the pedestal 1 without any gap.

By providing the cap-shaped member 20, the pedestal 1 is prevented from being deformed in the horizontal direction and the upper and lower directions by the load. In particular, even when the pedestal 1 is formed of an elastic body having a low hardness, it is possible to effectively prevent the sinking when a load is applied and the settling when a long-term load is applied.

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

FIG. 2 and FIG. 3 show another example of the structure of the pedestal 1 used in the floor board supporting device of the present invention, particularly a modification of the cap-shaped member.

In the modified example of FIG. 2, a cap-shaped member 21 similar to that of FIG. 1 is provided with a slight gap between it and the pedestal 1. The gap is appropriately determined according to various conditions such as the hardness of the pedestal 1 and the assumed load, but it is preferably in the range of 0 to 5 mm.

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

In the modified example shown in FIG. 3, a cap-shaped member 22 having an upright peripheral wall surface is attached to a pedestal 1 having a substantially trapezoidal cross-section, and the pedestal 1 has substantially no gap at the lower end. It is in close contact with the outer surface, but the gap becomes larger toward the upper end. This is because deformation of the pedestal due to load occurs from the upper part, so if the initial deformation at the upper part of the pedestal is suppressed, it will not be possible to sustain the shock absorbing effect and soundproofing effect for a long time. The upper gap is set large, and the lower gap is set small to suppress the sinking.

In the construction example shown in FIG. 1, the opposing end portions of the adjacent floor placement panels 16 are placed and supported on the support plate 3, but the central portion of the floor placement panel 16 is supported. You may construct so that it may be mounted and supported on the board 3.

Further, the floor board supporting device as shown in the figure can be used by being fixed in advance to a plurality of predetermined positions on the back surface of a base plate having a relatively large predetermined size. In this case, a through hole aligned with the through hole 10 in the support plate 3 is also formed in the base plate.

Further, the support plate 3 may be increased in size to be integrated with the base plate.

[0038]

EFFECTS OF THE INVENTION According to the present invention, it is possible to provide a floor board supporting device having excellent cushioning and absorbing effect against impact force from the floor surface and soundproofing effect in the floor placing structure.

Particularly, 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 direction and the vertical direction by the action of the cap-shaped member. As a result, problems such as the sinking of the floor surface due to the load after construction, the deterioration of walking sensation due to fatigue due to long-term load, and the level deviation of the floor itself do not occur.
