DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an underfloor support leg of a floor to be used for soundproofing and interior rationalization, and more particularly to a structure of an underfloor support leg having improved impact resistance, sound insulation and stability. Regarding the structure.

[0002]

2. Description of the Related Art In the interior construction of houses and offices, a construction method of laying a floor and then laying a partition in order to improve construction efficiency is performed.

The laying of the floor has advantages such as a soundproofing effect and the possibility of wiring and piping below the floor. Since the room partition can be laid efficiently on the floor, the construction period can be shortened and the cost can be reduced. .

[0004] Like business buildings, universities and research institutes,
When cables such as OA equipment and computers interfere with walking, they can be routed under the floor.

[0005]

In the prior art for laying a floor, a metal adjusting bolt and a screw member are used for a supporting portion for supporting the load applied to the floor and adjusting the height of the floor surface. . However, there is a problem of a squeak sound (floor sound) generated by the metal at a portion where the metal adjustment bolt and the screw member come into contact. In addition, since it is made of metal, sound is easily transmitted, and there is a problem that a high soundproofing effect cannot be obtained even if a sound absorbing material is arranged at the bottom of the pedestal in contact with the floor.

Further, the conventional underfloor support leg supports the plate member with one adjusting bolt. Therefore, in a place where a horizontal load is generated, such as a floor on which a partition is laid, the surface of the partition faces. There was also a problem that the strength in the direction was insufficient.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an underfloor support leg which suppresses floor noise and is excellent in soundproofing, and also in a place where a lateral load is generated, such as a floor with a partition. To provide a stable underfloor support leg.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The underfloor support legs of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially broken perspective view of an underfloor support leg used for placing a floor. FIG. 2 is a sectional view of an underfloor support leg used for placing the floor.

The underfloor support leg 1 used for the floor is a floor 1
It is located at one corner or side and supports the floor 11. Made of particle board (for example, with dimensions of 90 × 90 × 20 mm)
The adhesive 7 is applied or pasted on the upper surface of the plate member 6, and the floor 11 is arranged on the underfloor support leg 1. When laying the floor 11 in a room subjected to severe vibration or when the height of the floor 11 with respect to the floor is high, the floor 11 and the plate member 6 are firmly fixed by nailing from above the floor 11. Then, the flooring 14 for the interior, a carpet, a carpet, and the like are laid on the floor 11.

The plate member 6 serves to prevent the floor 11 placed thereon from warping. Therefore, it is preferable that the plate member 6 is made of resin so that the plate member 6 itself does not warp due to the moisture rising from the concrete floor. However, when it is necessary to nail the plate member 6, the plate member 6 is made of a particle board, and a thin (for example, 6
It is preferable to provide a resin plate 6a (having a size of 0 × 60 × 5 mm), and to integrally form the resin plate 6a when the screw hole member 5 is formed.

The adjustment bolt 4 made of synthetic resin (for example, having a diameter of 8 mm) has a screw head which can be rotated by a tool such as a screwdriver. Acting as a vertical force, the plate member 6 can be raised or lowered to easily adjust the height of the floor 11 (for example, to a height of 70 to 120 mm).

The other end of the adjusting bolt 4 is fixed to the pedestal 2 made of a synthetic resin (for example, the bottom diameter is 40 mm) with the adjusting bolt sound absorbing member 8 interposed therebetween. The screw hole member 5 and the pedestal 2 only need to have a shape capable of transmitting the horizontal force applied to the adjusting bolt 4 to the floor 10, and in addition to the truncated cone as shown in FIG. May be similar in shape.

The screw hole member 5, the adjusting bolt 4, and the pedestal 2
Is made of synthetic resin, transmission of sound from the floor 10 to the floor 11 and from the floor 11 to the floor 10 can be reduced. In addition, a sound absorbing member 3 is fixed to the lower surface of the pedestal 2 to prevent slippage and absorb vibration noise and the like.

It is more preferable to provide a hemispherical projection on the bottom surface of the sound absorbing material 3 to enhance the sound absorbing effect.

FIG. 3 is a perspective view of the underfloor support leg used for the floor joist, and FIG. 4 is a perspective view of the underfloor support leg used for the floor joist.

The solid joist 12 made of synthetic resin is fixed to the wall surface 16 with screws 15 with a floor noise preventing rubber 19 interposed therebetween. By using a synthetic resin as compared to conventional wood, deformation due to moisture and rot hardly occurs and floor noise is prevented.
In addition, the synthetic resin after recycling can be used,
It is even more economical. Also, rubber 19 for floor noise prevention is used.
Thus, it is possible to prevent the vibration of the floor 11 from being transmitted to the wall surface 16. The adhesive 7 is applied or stuck on the upper surface of the joist 12 so that the floor 11 does not slip. Furthermore, if the adhesive 7 is provided also on the side surface which comes into contact with the wall, it is easy to come into contact with the wall.

Underfloor support legs 9 used for wall joists 12
The plate member 6 is adjusted to the width of the joist 12 (for example, 4
It is the same as the underfloor support leg 1 used for the floor 11 except that the plate member 6 is made of synthetic resin and is narrow (to 5 mm). The foot 17 is mainly used to support the stone joists 12, but the underfloor support legs 9 are used to further enhance the soundproofing effect. The underfloor support legs 9 used for the joists need not be nailed, and are made of a less expensive synthetic resin because the material cost can be reduced. Also, if it is made of synthetic resin,
It is hard to be deformed due to moisture and rot generated when wooden, and it prevents floor noise.

FIG. 5 is a partially cutaway perspective view of the double leg and the partition.

A large force is applied to the floor 11 on which the partition 13 is disposed in the direction of the surface of the partition 13. In order to obtain high strength, the elongated plate member 6 (having a size of, for example, 290 × 90 × 20 mm) is shared, and the screw hole member 5, the adjusting bolt 4, the sound absorbing member 8 for the adjusting bolt, the pedestal 2, and the sound absorbing member 3 are provided.
Are attached to the plate member 6 in pairs.

Although there is a column at the junction between the partitions 13, the use of the double legs 20 enhances the load-bearing characteristics and prevents the floor 11 and the flooring 14 from being deformed.

[0025]

The underfloor support leg of the present invention suppresses floor noise by making the screw hole member and the adjustment bolt made of synthetic resin.
Excellent soundproofing effect. Further, by making the plate member of the underfloor support leg used for the floor joists made of synthetic resin, material costs can be reduced. Further, by making the underfloor support legs used for the partition a double leg, the strength is increased even in a lateral load, and the partition and the column are also stable.
