[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 elastic 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 solely on the elastic performance of the elastic body itself of the pedestal, and cannot sufficiently absorb the impact. It was

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. Will end up.

Further, there is a problem in that the elastic pedestal becomes depressed due to a long-term load and the level of 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, the present invention is a floor plate in which an elastic pedestal installed on a floor base and a pedestal that directly or indirectly supports a floor material are connected by a relatively rotatable strut so that height intervals can be adjusted. In the supporting device, a concave portion surrounded by a contour wall is provided on the bottom surface of the elastic pedestal.

The recessed portion on the bottom surface of the elastic pedestal can be filled with an elastic body having elasticity higher than that of the elastic pedestal.

【Example】

 FIG. 1 shows an example of the construction of a floor board supporting device according to the present invention, which includes an elastic base 1, columns 2 supported by the elastic base 1 in an upright state, a support plate 3, and fixedly attached to the support plate 3. And a receiving seat 4 to which the upper end of the column 2 is attached.

The elastic pedestal 1 is formed of a rubber-based, foamed rubber-based, synthetic resin-based, foamed synthetic resin-based elastic body or the like, and absorbs shock force. The shape of the elastic 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.

A recess 22 surrounded by a contour wall 21 is formed on the bottom surface of the elastic pedestal 1. In the illustrated embodiment, the ring-shaped recess 22 is used, but it may be spiral, checkerboard-shaped, diamond-shaped, or the like. Since the recess 22 surrounded by the contour wall 21 is formed on the bottom surface of the elastic pedestal 1 as described above, when installed on the floor base 15, the void formed between the base 22 and the floor base 15 serves as a buffer layer. Since it functions, the cushioning of the impact force is more effectively performed in combination with the elasticity of the elastic pedestal 1 itself.

The recess 22 is filled with an elastic body such as a rubber-based, foamed rubber-based, synthetic resin-based, or foamed synthetic resin-based elastic body having a higher elasticity than the elastic body forming the elastic pedestal 1. You can

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 elastic pedestal 1, and the pedestal 1 formed on the upper part of the round bar 6. A brim portion 7 having a diameter sufficiently larger than the diameter of the non-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 supported rotatably relative to the elastic 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.

Through holes 10 are formed in the support plate 3 at positions aligned with the bolt portions 8 of the columns 2 supported by the elastic 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 facilitate portability and good workability, but on the other hand, if it is too small, the number of sheets required for construction will increase and the construction will be 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 discarding plywood with adhesive or nails, the desired flooring is used with adhesives or nails. A fixed floor structure can be obtained by sticking together.

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, 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 can be formed between the part 8 and.

After adjusting the heights of the support plate 3 and the floor placement panel 20, a room temperature curable resin or adhesive (including a foaming adhesive and a foaming adhesive) is injected into the void. The injected resin fills the void and partly penetrates into the nut portion 11. By hardening the injected resin, the bolt portion 8 is completely fixed to the receiving seat 4, and the additional effect that the support plate 3 is fixedly held at a predetermined height position is obtained.

[0027]

[Effect of device]

 According to the present invention, it is possible to provide a floor board support device having an excellent cushioning and absorbing effect against the impact force from the floor in the floor structure and a soundproof effect.

Since the desired shock absorbing effect can be obtained without increasing the elasticity of the material of the elastic pedestal more than necessary, the floor surface will sink due to the load after construction, or walking due to fatigue due to long-term load There will be no problems such as deterioration of feeling and occurrence of level deviation of the floor itself.

Since the recessed portion is formed on the bottom surface of the elastic pedestal, the ground contact area with the floor base is reduced, so that the propagation of impact force to the floor base is reduced.
