Description

[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]

 Such a floor board supporting device generally has an elastic pedestal such as rubber attached to the lower end of a rod-shaped leg portion, as disclosed in Japanese Patent Laid-Open No. 2-269254. A non-through hole is provided on the upper surface of the elastic pedestal, and the lower end of the bar-shaped leg is inserted into the non-through hole to support the bar-shaped leg.

The floor board support device having such a structure absorbs shocks by the elasticity of the pedestal to improve vibration and soundproofing.

[0004]

[Problems to be solved by the device]

 Floor impact sounds include the sound of falling light objects such as a spoon (light hard impact source) and the sound of falling heavy objects such as children's jumps (heavy soft impact source). The above-mentioned conventional floor board supporting device exerts an effective cushioning action against a light and high impact source, but the support device jumps against a heavy and soft impact source, and the rod-shaped legs are pedestal-shaped. Sometimes jumped out of the non-penetrating holes on the top surface of the. The fall of the rod-shaped legs causes the floor to sink and becomes a very serious problem.

In the case of the floor board supporting device having the above-mentioned configuration, the absorbing action for the impact on the floor depends on the elastic performance of the elastic body itself of the pedestal, and it is difficult to sufficiently absorb the impact. In order to improve the elastic performance, the pedestal may be made of a material with high elasticity, but in this case, the subsidence becomes large when the load is applied after construction, and the walking feeling deteriorates, and the furniture It will be difficult to install such as stable. In addition, there is a problem that the pedestal becomes depressed due to a long-term load and the level of the floor itself is distorted.

[0006]

[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 that directly or indirectly supports a floor material are connected to each other by columns that can rotate relative to each other so that height intervals can be adjusted. The apparatus is characterized in that a diameter-increased portion is provided at a lower portion of the column and the diameter-increased portion is embedded in an elastic pedestal.

[0008] Preferably, an insertion hole into which the lower portion of the column is inserted is formed in the elastic pedestal, and a concave groove into which the expanded diameter portion is fitted is provided in the insertion hole.

Further, a ring-shaped member for preventing horizontal deformation of the elastic base can be attached to the elastic base. A gap of 0 to 5 mm is preferably arranged between the outer surface of the elastic pedestal and the inner surface of the ring-shaped member.

[0010]

[Action]

 The expanded diameter part provided at the lower part of the column is embedded in the elastic pedestal to prevent the column from falling off the elastic pedestal even when a heavy soft impact source acts on the floor.

The ring-shaped member attached around the elastic pedestal prevents deformation of the pedestal in the horizontal direction when a load is applied.

[0012]

【Example】

 FIG. 1 shows a structural example of a floor board supporting device 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, a support plate 3, and The receiving plate 4 is fixedly attached to the support plate 3 and engages the upper end of the support column 2.

The elastic pedestal 1 is formed of an elastic body such as a rubber type, a foamed rubber type, a synthetic resin type, or a foamed synthetic resin type, and cushions and absorbs impact force. The elastic body forming the elastic pedestal 1 has a hardness of 30 to 90 degrees. When the hardness is less than 30 degrees, the subsidence when a load is applied becomes large and the walking feeling deteriorates, and when a long-term load is applied, the tiredness occurs 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.

At the center of the upper surface of the elastic pedestal 1, there is formed a non-through hole 5 for inserting a lower end round bar 6 (described later) of the support 2 to support the support 2 in an upright state. The diameter of the non-through hole 5 is substantially the same as the outer diameter of the round bar 6, but a part of it is cut out to a larger diameter to form an annular groove 18. The concave groove 18 is for fitting and receiving the expanded diameter portion 17 (described later) provided in the lower portion of the supporting column, and therefore their shapes are complementary to each other, and is different from the brim portion 7 (described later) of the supporting column 2. The interval between the expanded diameter portion 17 and the upper surface of the elastic pedestal 1 and the groove 18 is substantially the same. 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.

The pillar 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 on the upper surface of the elastic pedestal 1, and a non-through hole of the elastic pedestal 1 formed above the round bar 6. A brim portion 7 having a diameter sufficiently larger than the bore of No. 5 and a bolt portion 8 extending above the brim portion 7 and having a groove 9 formed at its tip are integrally formed. The expanded diameter portion 17 is provided at the tip of the round bar 6 as described above. The expanded diameter portion 17 does not necessarily have to be provided at the lowermost end portion of the round bar 6 and may be formed in the middle portion of the round bar 6 (see FIG. 5).

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 elastic pedestal 1. By inserting the lower end round bar 6 of the column 2 into the non-through hole 5 of the elastic pedestal 1 and pressing it downward, the peripheral portion of the non-through hole 5 of the elastic pedestal 1 is elastically deformed by the expanded diameter portion 17. The diameter is expanded, and finally the expanded diameter portion 17 is fitted into the concave groove 18. At this time, the elastic pedestal 1 is restored to the state shown in the figure, so that the column 2 is prevented from falling off the elastic pedestal 1 upward.

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 square shape with one 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 placement panel 16 installed 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, an adhesive layer (not shown) surface-coated with a release paper (not shown) should be laminated to facilitate the construction of the floor placement panel 16. You can

The metal or synthetic resin seat 4 has a lower end nut portion 11 on which a female screw for screwing the 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 flooring support device. Is provided.

Materials such as plywood (including LVL, LV B, etc.), fiber board, particle board, wood board, synthetic resin board, etc. are used for the floor placement panel 16 placed and installed on the support board 3. 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 entire room, directly or after fixing the throwing plywood with adhesive or nails, the desired flooring material 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. The floor can also be constructed by applying a floor coating material to 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 are 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.

In the illustrated embodiment, the elastic pedestal 1 is covered with a ring-shaped member for preventing excessive elastic deformation in the horizontal direction. The ring-shaped member is shown in FIG. 1 as a ring-shaped member 20 which is attached to the outer surface of the elastic pedestal 1 so as to be in close contact with it without a gap.

By providing the ring-shaped member 20, horizontal deformation of the elastic pedestal 1 due to a load is prevented. In particular, even when the elastic 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 ring-shaped member is generally made of metal or synthetic resin. The material, width and thickness of the ring-shaped member vary depending on the hardness of the elastic pedestal 1 and the assumed load that varies depending on the place of use of the floor board supporting device. It is arbitrarily selected and determined according to various conditions.

2 to 5 show another structural example of the elastic pedestal 1 used in the floor plate supporting apparatus of the present invention, and particularly show a modified example of the ring-shaped member.

In the modification of FIG. 2, a ring-shaped member 21 similar to that of FIG. 1 is provided with a slight gap between it and the elastic pedestal 1. The clearance 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 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 modification shown in FIG. 3, an elastic pedestal 1 having a substantially trapezoidal cross section is covered with an upright cylindrical ring-shaped member 22, and the lower end of the elastic pedestal 1 has substantially no gap. It is in close contact with the outer surface, but the gap becomes larger toward the upper end. This is because the elastic pedestal is deformed by the load from the upper part, so if the initial deformation is suppressed at the upper part of the elastic pedestal, the shock absorbing effect and soundproofing effect cannot be maintained for a long time. In consideration of this, the upper gap is set large, and the lower gap is set small in order to suppress sinking.

A plurality of ring-shaped members may be provided. For example, as shown in FIG. 4, ring-shaped members 23 having a relatively small width may be attached to the elastic pedestal 1 as shown in FIG. In the construction example, the opposite 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 placed and supported on the support plate 3. It may be installed.

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.

FIG. 5 shows another embodiment of the floor board supporting device according to the present invention, and particularly shows a modification of the elastic pedestal 31. The bottom surface of this elastic pedestal 31 is formed in an uneven shape to further improve the cushioning action. The uneven bottom surface can be obtained, for example, by engraving grooves in a stripe pattern or a grid pattern.

Further, the annular recess 38 provided in the non-through hole 35 of the elastic pedestal 31 is formed so as to fit the enlarged diameter portion 37 provided in the middle portion of the round bar 6 of the support column 2.

Since the configuration other than the above is the same as that of the embodiment shown in FIG. 1, its explanation is omitted. A ring-shaped member may be adhered to the elastic pedestal 31 in close contact with or with a gap therebetween to prevent or suppress elastic deformation in the horizontal direction.

[0041]

[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.

In particular, even when a heavy soft impact source generated by the jumping of a child on the floor or the like is received, the column is prevented from falling off the elastic pedestal, and the floor board is not hindered. .

Further, even when the elastic pedestal is formed of an elastic body having a small hardness in order to enhance the shock absorbing effect and the soundproofing effect, the deformation of the elastic pedestal in the horizontal direction is effectively prevented by the action of the ring-shaped member. As a result, there will be no 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 occurrence of level deviation of the floor itself.
