DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry soundproof double floor structure provided at a predetermined height from a floor base such as a concrete slab, and more particularly to a wall portion of the dry soundproof double floor structure. Related to the structure.

[0002]

2. Description of the Related Art An edge joist structure is used near a wall of a dry double floor. FIG. 8 is a longitudinal sectional view of an architectural structure using such a joist structure.

[0003] As shown in FIG. 8, a building structure 51 includes a dry double floor 52 and walls 53. The dry double floor 52 includes a floor base 54 such as a concrete slab, a support leg 55 on the floor base 54, a particle board 56 supported by the support leg 55, and a surface floor material 57 on the particle board 56. The surface flooring 57 includes a plywood 57a and a finishing material 57b.

The joist structure 60 supports the dry double floor 52 on the wall 53 side adjusted to a predetermined height from the floor base 54 with the bundle 58 and the joist material 59.

[0005] The bundle 58 is in close contact with the floor base 54 and the wall 53, and a joist 59 is placed on the bundle 58. The joists 59 are fixed to the wall 53 with nails 61. A baseboard 62 is provided above the dry double floor 52 on the side of the wall 53.

[0006]

In such a case, the joist structure 60 is used.
Is very effective to prevent the dry double floor 52 from sinking around the wall 53 that partitions the floor base 54 as shown in FIG.

However, in this case, in the joist structure 60, the impact applied to the surface floor material 57 is transmitted directly to the wall 53 and the floor base 54 through the joist material 59 and the bundle 58, and the dry double floor 52
Significantly lowers the sound insulation downstairs.

[0008] For this reason, the necessity of employing a joist structure in such a case is a very serious problem in terms of measures against noise.

The inventor of the present invention has clarified that the reason that the floor can be prevented from sinking unless the joist structure is adopted is caused by the warpage of the particle board supported by the support legs.

In addition, the inventor of the present invention has proposed that in the construction of the joist structure, the bundle 10 and the joist material 11 besides the dry soundproof double floor.
Has to be constructed, which is costly and time consuming.

According to the present invention, without using a joist structure,
It is an object of the present invention to obtain a dry soundproof double floor structure capable of preventing the floor from sinking. Another object of the present invention is to provide a building that can improve the sound insulation performance downstairs.

[0012]

SUMMARY OF THE INVENTION The present invention provides a dry soundproofing system comprising a floor base, support legs on the floor base, particle hods supported by the support legs, and a surface floor material on the particle board. In a double floor structure, at the periphery of the dry soundproof double floor structure, an elongated straightening member is fixed to the lower surface of the outer end of the particle board,
The dry soundproof double floor structure, wherein the straightening member corrects a warp of an outer end portion of the particle board, and a space is formed between the straightening member and the floor base. This is a construction method for a dry soundproof double floor structure.

[0013] The present invention also relates to a building comprising the dry soundproof double floor structure and a wall on the floor base, between the correction member and the wall and an outer end of the particle hoard. And a cushioning material is provided on at least one of the wall and the wall.

The present inventor made various prototype structures and examined various types of building structures in order to avoid the use of the joist structure and to improve the sound insulation performance at the wall portion of the dry soundproof double floor.

Of the building structures prototyped by the inventor, the building structure 31 as shown in FIGS. 4 and 5 was the most excellent. FIG. 4 is a vertical cross-sectional view of a wall of the architectural structure of the prototype. FIG. 5 is a rear view in which a part of the building structure of FIG. 4 is cut away.

The building structure 31 includes a prototype floor structure 32 and a wall 33.
And The prototype floor structure 32 includes a floor base 34 and a floor base 3.
4 comprises a supporting leg 35, a particle board 36 supported by the supporting leg 35, and a surface flooring 37. Surface flooring 37
Consists of a plywood 37a, a finishing material 37b, and the like.

In this building structure 31, reinforcing support legs 38 are attached at several places on the wall 33 side of the particle board 36, as shown in FIG.
The particle board 36 was supported. A baseboard 39 is provided above the wall 33 of the prototype floor structure 32.

The present inventors have studied such a building structure in more detail. As a result, the present inventor has found that a gap 40 is generated between the baseboard 39 and the finishing material 37b in the building structure as shown in FIGS. 4 and 5, as shown in FIG. . FIG. 6 is a side view of the building structure of FIGS. 4 and 5 as viewed from the B direction.

As shown in FIG. 6, in such a prototype floor structure, there is always a gap 40 between the baseboard 39 and the finishing material 37b.
Then, the support leg 38 itself floats above the floor base 34 to create a space 41.

In this prototype floor structure 31, it has been found that the floor surface near the wall sinks even under a low load, and a horizontal stable floor surface cannot be obtained.

Further, it can be seen that, when a part of the floor sinks, the walking feeling is impaired, and the gap between the baseboard 39 and the finishing material 37b is further widened, and the appearance is significantly impaired. Was.

Based on such knowledge, the present inventors have made intensive studies on the cause of the floating of the support leg at the wall. As a result, the present inventor has found that the floating of the support legs is caused by the warpage of the particle board itself.

FIG. 7 is a perspective view of the particle board. As shown in FIG. 7, in the particle board 42, at least a pair of opposed ends 42a and 42b are warped upward or downward.

When the particle board is used as a floor material, one or two or more surface floor materials such as a plywood or a finishing material are applied to the upper surface thereof. For this reason, the warpage of the particle board is reduced, and the height of the particle board can be maintained at a predetermined interval by supporting the warped portion of the particle board with the support legs at the four corners.

However, the reduction in warpage of the particleboard depends on the weight and strength of the surface flooring thereon.

Therefore, the warpage of the particle board used in the center of the room increases the binding force due to the strength of the surface flooring material, and is easily reduced by the weight, and becomes a surface load. Only the part is displaced as a surface without lowering. Therefore, the particle board can be sufficiently supported by the support legs having a predetermined height.

However, the warp of the particle board used near the wall of the room has a weak binding force of the surface floor material, and it is difficult to sufficiently reduce it. For this reason, as shown in FIG. 6, a gap 40 is generated between the baseboard 39 at the wall and the finishing material 37b.

In order to reduce the warpage of the particle board, there is naturally a limit in increasing the weight of the surface flooring material. In the vicinity of the wall of the prototype floor structure, there is a gap between the baseboard 39 and the finishing material 37b. Always produces a gap 40.

Further, in the prototype floor structure, a supporting leg 38 for reinforcement as shown in FIG. 5 is used instead of the joist structure.
Accordingly, as shown in FIG. 6, when the warpage of the particle board 36 is reduced, the supporting legs 38 for reinforcement can be used.
It floats.

Based on such knowledge, the present inventors have studied the floor structure in more detail in order to eliminate the warpage of the particle board at the wall and to obtain a dry soundproof double floor structure capable of preventing sinking of the floor. did.

As a result, the present inventor provided an elongated straightening member on the periphery of the dry soundproof double floor structure, and caused the straightening member to correct the warp of the outer end portion of the particle board, thereby forming the joist structure. Without using it, the inventors found out that the wall portion of the dry soundproof double floor structure was supported by the supporting legs having a predetermined height, and arrived at the present invention.

In the present invention, since the warp of the outer edge of the particle board at the peripheral portion of the dry soundproof double floor structure is corrected in advance, the outer side of the particle board is placed on the support legs provided on the floor base. Even if the end portion is placed and the surface floor material is placed on the particle board, the particle board does not deform and the support legs do not float.

Further, according to the present invention, since the warp of the outer edge of the particle board at the peripheral portion of the dry soundproof double floor structure is corrected in advance, even if the surface floor material is placed on the particle board, There is no gap between the baseboard and the surface flooring.

According to the dry soundproof double floor structure of the present invention, the outer end portion of the particle board is securely supported at a predetermined height by the support legs without using the joist structure, so that it is greatly improved. It is possible to provide a smooth floor surface in which the sink can be improved and a partial displacement due to the load does not occur.

According to the dry soundproof double floor structure of the present invention, since no edge joist structure is used, extremely excellent soundproofness is exhibited.

In addition, the inventor of the present invention has proposed that when such a dry soundproof double floor structure is provided adjacent to a wall on the floor base, the particle board itself is laid down at the time of construction. And the floor material on the surface thereof are easily moved, come into contact with the wall, become a noise generating source, or have poor durability.

Based on such knowledge, various types of buildings including a dry soundproof double floor structure and walls were constructed and examined in detail. By providing cushioning material between the outer end of the hood and the wall, we ascertained that the wobbling of the particle board and the direct contact of the particle board with the wall were effectively and reliably prevented, and completed the present invention I let it.

According to the building of the present invention, the cushioning material is provided at least between the straightening member of the particle board and the wall and between the outer end of the particle board and the wall, so that the dry soundproofing is achieved. The generation of noise due to the contact between the double floor structure and the wall can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view of a building using a dry soundproof double floor structure according to an example of the present invention, near a wall of a building. FIG.
FIG. 2 is a plan view of the building of FIG. 1 with a part cut away. FIG. 3 is a side view of the building of FIGS. 1 and 2 viewed from the direction A.

As shown in FIGS. 1 and 2, the dry soundproof double floor structure 1 of the present invention comprises a floor base 2, a support leg 3 on the floor base 2, and a particle board 4 supported by the support leg 3. And a surface flooring material 5 on the particle board 4, and is provided adjacent to the wall 6. The surface flooring 5 includes a plywood 5a or the like, a finishing material 5b, and the like.

In the dry soundproof double floor structure 1,
An elongated correction member 7 is provided at the peripheral portion. The straightening member 7 is fixed to the lower surface of the outer end 4a of the particle board 4, and corrects the warp of the outer end 4a of the particle board 4.

Further, in the dry soundproof double floor structure 1, a space 8 is formed between the correction member 7 and the floor base 2.

In the dry soundproof double floor structure of the present invention, a correction member capable of correcting the warpage of the particle board is fixed to the lower surface of the outer end of the particle board disposed at the peripheral edge.

In such a dry soundproof double floor structure, since there is no warpage of the particle board, the particle board is adjusted to a predetermined height by the support legs, so that the support legs themselves are prevented from floating from the floor base, and a low load is applied. The sink of the floor is prevented.

In the dry soundproof double floor structure of the present invention,
Instead of using a joist structure, fixing the correction member to the particle board with a space provided between the floor base and the floor can prevent sinking of the floor surface. The propagation of directly transmitted sound is also greatly reduced, and the sound insulation of downstairs can be kept even higher.

The correction member according to the present invention corrects the warpage of the particle board, and various types of particles can be used as long as the particle board is reliably supported at a predetermined height by the support legs and the surface floor material does not sink. Can be used.

As the correction member, a single-ply laminated material can be used. By using the veneer laminate, the deflection of the particle board can be significantly reduced, and the sink of the floor itself can be significantly reduced.

The single-layer laminated material can be integrated and fixed to the lower surface of the peripheral edge of the particle board with screws or the like.

Such a veneer laminate must be used vertically, ie vertically. In the case of horizontal or flat use, warpage occurs on the upper and lower surfaces, and in horizontal shear strength,
This is because flat use is inferior in strength.

The single-ply laminated material suppresses the warpage of the particle board, thereby preventing the gap between the baseboard and the finishing material, preventing the floor from partially sinking under a low load, and furthermore, The deflection of the particle board can be significantly reduced.

Regarding the position for attaching the single-layer laminated material to the particle board, the dry-sound-proof double floor structure near the wall is preferable from the viewpoint of workability. Good.

The length of the veneer laminate is preferably the same as the panel size of the particle board. However, it is sufficient that the length is equal to or larger than the distance between the support legs.

The construction method of the dry soundproof double floor structure of the present invention will be described. In the present invention, first, an elongated correcting member 7 is fixed to the lower surface of the outer end 4a of the particle board 4 disposed on the peripheral portion of the dry soundproof double floor structure as shown in FIGS. This corrects the warpage of the outer end 4a of the particle board 4.

Next, the corrected particle board 4 is placed on the support leg 3 as shown in FIGS. 1 and 2, and the surface flooring 5 is placed on the particle board 4.

In such a dry soundproof double floor construction method, the warpage of the particle board is corrected in advance by the correction member, and the warp of the particle board is not corrected depending on the binding force and weight of the surface floor material. The height of the supporting legs can reliably support the particle board.

Further, in the construction method of the dry type soundproof double floor structure, since the warp of the particle board is not corrected again by the surface floor material, the support legs do not float.

Further, the method for constructing such a dry soundproof double floor structure does not require the use of a joist structure, is inexpensive, has excellent workability, and can form a space between the straightening member and the floor base. Therefore, a dry soundproof double floor structure with excellent sound insulation can be obtained.

According to the present invention, as shown in FIG. 3, the warp of the particle board 4 supported by the support leg 3 is corrected by the correction member 7 before the surface flooring 5 is applied. Since it does not deform after the flooring 5 is installed, even if the reinforcing support legs 9 are provided, the reinforcing support legs 9 do not float from the floor base 2 and the particle board is supported at a predetermined height.

The building of the present invention is obtained by using such a dry soundproof double floor structure. As shown in FIG. 1, a building 11 according to an example of the present invention includes a dry soundproof double floor structure 1 and a wall 12 on a floor base 2.

Such a cushioning material can prevent the sound generated by the vibration of the dry soundproof double floor structure from propagating to the wall.

In the building according to the present invention, the cushioning material is provided between the wall and the correction member or the particle hod which is laid down at the time of construction. Can be prevented.

Further, in the building according to the present invention, even if the laid-down particle board or the correction member moves during the construction, the contact between these and the wall is suppressed by the cushioning material, and the particle board and the correction member Vibration of the members does not reduce the durability of the building or cause noise.

Further, in the building of the present invention, as shown in FIG.
Is corrected by the correction member 7 and the baseboard 13
There is no gap between the floor material and the floor material 5.

As the cushioning material according to the present invention, a material made of one or more materials of general-purpose foams such as polyethylene, polypropylene and polyurethane, or fiber yarns or rubber elastic materials such as polyester and nylon can be used. .

The cushioning material is provided between the straightening member or the particle board and the wall to insulate the dry soundproof double floor structure from the wall and to prevent the propagation of vibration of the floor structure. It is only necessary that the laminated material and the particle board do not directly contact the wall.

In addition, such a cushioning material can be provided on the entire periphery or a part of the periphery of the correction member or the particle board. It is preferable to partially provide such a cushioning material in consideration of labor and cost.
