Description

[Detailed Description of the Invention] The present invention relates to a flooring support structure for supporting flooring by being attached to the foundation of a building such as an apartment complex.

Conventional flooring support structures include a structure in which the flooring is installed on the concrete slab that is the foundation of the building, and then the flooring is laid on top of the joists; A structure is used in which the flooring is placed on top of the joists and the flooring is installed on top of the joists.

However, in such a conventional flooring support structure, since the supporting materials such as joists are made of wood, shocks and vibrations applied to the flooring material are transmitted to the downstairs floor via these supporting structures. This results in poor floor impact sound isolation performance. In addition, wooden floor joists and bundles shrink as they dry, leaving gaps in their contact surfaces, which can easily cause floor squeaks.

In consideration of the above facts, the present invention aims to provide a floor material support structure that has excellent floor impact sound insulation performance and can eliminate floor squeak noise.

The flooring support structure according to the present invention reduces impact noise by attaching long rod-shaped flooring supports to the horizontal plate portions of fasteners installed at appropriate intervals on the building foundation through elastic bodies and receivers. The material is absorbed by the human body, gives appropriate elasticity to the flooring material, and the upper part of the elastic body placed between the rod-shaped long flooring support and the building foundation is placed between the flooring material and the building foundation to absorb horizontal force. It is designed to absorb and prevent sideways movement.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a first embodiment of the present invention, in which a wall material 12 that constitutes a building foundation together with a concrete slab 10 is provided with fasteners 14 at appropriate intervals in the horizontal direction. . The side surface of this stopper 14 is approximately T-shaped as shown in FIG. The foot portion of this stopper 14 is a horizontal plate portion 14A arranged horizontally,
The head 14B intersects this horizontal plate 14A perpendicularly. This head 14B is concrete nail 1
It is fixed to the wall material 12 at 6. Instead of the concrete nails 16, suitable fixing means such as screws can be used.

The horizontal plate portion 14A of the stopper 14 and the head portion 14B protruding above the horizontal plate portion 14A include a horizontal portion 18A and a vertical portion 18.
An L-shaped elastic body 18 having a B is placed. This elastic body 18 can be made of rubber or the like, and at least the horizontal portion 18A is fixed to the horizontal plate portion 14A of the stopper 14 with adhesive or the like.

Further, an L-shaped bracket 20 is placed on the horizontal portion 18A of the elastic body 18, and has a horizontal portion 20A and a vertical portion 20B like the elastic body 18, but at least the horizontal portion 20A is coated with adhesive. etc., and is fixed to the horizontal portion 18A. This receiving metal fitting 20
A bolt 22 stands vertically from the horizontal portion 20A, and has a male thread formed at its upper end.

In this way, as shown in FIG. 1, a plurality of the fasteners 14, the elastic bodies 18, and the receivers 20 are installed at the same height at appropriate intervals in the lateral direction of the wall material 12. A wooden rod-shaped elongated flooring support 24 is placed on the portion 20A. This floor material receiver 24 has stepped through holes 2 corresponding to the bolts 22.
6 is drilled, and the washer 28 is attached to the bolt 22.
The flooring receiver 24 is fastened to the horizontal portion 20A by screwing the nut 30 onto the bolt 22 after the screw is fitted.

A floor material 32 is laid on this floor material receiver 24. An end surface 32A of this floor material 32 on the wall material 12 side corresponds to an upper end portion 18C of the vertical portion 18B of the elastic body 18.

The vertical portion 18B of the elastic body 18 has an upper end portion 18C.
Its height is set so that it is placed between the end surface 32A of the flooring material 32 and the wall material 12, and the horizontal force of the flooring material 32 is absorbed when the flooring material 32 moves in the direction of the wall material 12. The flooring material 32 was used at the time of construction.
The end face 32A of the wall material 12 is arranged so as not to come into direct contact with the wall material 12.

In this embodiment configured in this way, the flooring material 32
The shock and vibration applied to the
Since the shock and vibration are mainly absorbed by the horizontal portion 18A of the elastic body 18, almost no impact or vibration is transmitted to the downstairs through the wall material 12. Further, since the long flooring support 24 is placed on the elastic body 18 via the receiving metal fitting 20, friction may occur between the flooring material support 24 and the receiving metal fitting 20 or between the receiving metal fitting 20 and the elastic body 18. No squeaks will occur. In addition, the elastic body 18 imparts elastic force to the flooring material 32, making it ideal for floor structures for competitions such as gymnasiums that require a certain level of elasticity, and for residential floor structures that require insulation against floor impact noise. becomes.

In addition, since the elastic body 18 is interposed between the end surface 32A of the flooring material 32 and the wall material 12, the end surface 32A of the flooring material 32 does not come into contact with the wall material 12 during construction, and there is no gap between the two during construction. Does not generate squeaks. Furthermore, even if a horizontal force is applied to the flooring during an earthquake or the like, this horizontal force is absorbed by the elastic body 18, thereby preventing lateral shaking.

Next, FIG. 3 shows a second embodiment of the present invention, in which the elastic body 18 has a horizontal portion 18A and a vertical portion 18B.
A configuration in which the two are separated is shown, and a gap 34 is formed between the two.

However, in this embodiment as well, the other parts have the same shape as in the previous embodiment, and the same effects can be obtained.

Next, FIG. 4 shows a third embodiment of the present invention, in which the stopper 14 is L-shaped with the head 14B above the horizontal plate part 14A omitted, and the receiver 20 is also The vertical portion 20B in the first embodiment is omitted, and the other structure is the same as that in the first embodiment. In this embodiment, there is a slight gap between the vertical part 18B of the elastic body 18 and the wall material 12, but the vertical part 18B of the elastic body 18 is in contact with the side surface of the rod-shaped long floor material receiver 24. There is.

In this embodiment as well, the elastic body 18 absorbs shocks and vibrations applied to the floor material 32 and
4 and the receiving metal fitting 20, and between this receiving metal fitting 20 and the elastic body 18, no squeak is generated, and the vertical portion 18B of the elastic body 18 prevents the end surface 32A of the flooring material from coming into contact with the wall material 12. At the same time, it also absorbs horizontal forces.

Next, FIG. 5 shows a fourth embodiment of the present invention, in which the vertical portion 18B of the elastic body 18 is
8C terminates below the floor material 32. Further, the vertical portion 20B of the receiving metal fitting 20 has its upper end rising up to about the middle of the wall thickness of the floor material 32 and terminating therein.

Therefore, this vertical portion 20B receives the horizontal force of the floor material 32, and this horizontal force is absorbed by the elastic body 18.

The other configurations are the same as those of the first embodiment, and similar effects can be obtained.

As explained above, the floor material support structure according to the present invention receives the long floor material on which the floor material is placed, and is placed on the horizontal plate part of the stopper via the metal fitting and the elastic body, so that it is not added to the floor material. It absorbs shocks and vibrations and has excellent insulation against floor impact noise from downstairs, prevents floor noise, provides appropriate elasticity to the flooring material, and the vertical part of the elastic body is placed between the flooring material and the building foundation. Therefore, it has the effect of absorbing horizontal forces such as those caused by earthquakes and preventing lateral shaking.
