Abstract

PURPOSE:To absorb vibration positively by floor material and heighten sound insulating performance. CONSTITUTION:Backing plywood 2 is placed on joists 1, and a vibration-proof panel 3 formed by interposing vibration-proof material 3b between a pair of opposed thin plywood 3a is placed on the backing plywood 2. Plywood 4 is then placed on the vibration-proof panel 3, and cushioning material 5 is placed on the plywood 4. The respective members are mutually bonded in the laminated state using adhesive. The backing plywood 2 is fixed to the joists by nails 7, and the plywood 4 is fixed to the vibration-proof panel 3 by nails 8. A nail 9 is driven into the thin plywood 3a, disposed on the upper part of the vibration- proof panel 3, from the upper face of floor finishing material 6 so as to fix the floor finishing material 6, cushioning material 5, plywood 4 and vibration- proof panel 3 by the nail 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof floor capable of improving the soundproofness of a floor in a room.

[0002]

2. Description of the Related Art Conventionally, there is a floor shown in FIG. 2 in consideration of soundproofing. This product is constructed by sequentially laminating a base plywood 2, a cushioning material 5 composed of a rubber mat or a urethane mat, and a floor finishing material 6 on a joist 1 and laminating and bonding each panel with an adhesive. At the same time, nails 9 that have been driven in from the surface of the floor finishing material 6 are driven into the joists 1 to fix each panel, thus forming a soundproof floor.

[0003]

However, in the conventional example as described above, the nail 9 is used as the base plywood 2 when the soundproof floor is constructed.
The vibration on the floor finishing material 6 propagates through the nails 9 to reach the base plywood 2 and the joists 1 in order to pass through the joists 1 through to the joists 1, and even if the cushioning material 5 is provided, the soundproof performance is low. There was a problem that it would end up.

The present invention is intended to solve the above problems, and vibrations can be reliably absorbed by a floor material.
The purpose of the present invention is to provide a soundproof floor with high soundproof performance that does not propagate to plywood or joists.

[0005]

According to the present invention, in order to achieve the above object, a base plywood 2 is placed on a joist 1 and a vibration damping material 3b is interposed between a pair of thin plywoods 3a facing each other. The constructed anti-vibration panel 3 is placed on the base plywood 2, the plywood 4 is placed on the anti-vibration panel 3, the cushioning material 5 is placed on the plywood 4, and the flooring material is placed on the cushioning material 5. 6 is placed, each member is laminated and adhered to each other with an adhesive, the base plywood 2 is fixed to the joist 1 with nails 7, the plywood 4 is fixed to the vibration-proof panel 3 with nails 8, and the floor finishing material 6 The nail 9 is driven into the thin plywood 3a arranged on the upper side of the vibration isolating panel 3 from the upper surface of the above, and the floor finishing material 6, the cushioning material 5, the plywood 4, and the vibration isolating panel 3 are fixed by the nail 9.

[0006]

The vibration on the floor finishing material 6 is received by each panel, the cushioning material 5, and the vibration isolating panel 3, so that the vibration does not reach under the floor. Then, the vibration on the floor finishing material 1 is applied by the nail 9 and the nail 8 to the vibration-proof panel 3
However, the vibration is absorbed by the vibration-proof material 3b that constitutes the vibration-proof panel 3, and the vibration does not reach the base plywood 2 and joists 1.

[0007]

The present invention will be described below in detail based on the illustrated embodiments. The soundproof floor is constructed by sequentially laminating a base plywood 2, a vibration-proof panel 3, a plywood 4, a cushioning material 5, and a floor finishing material 6 on a joist 1 and each panel body is bonded and fixed to each other with an adhesive. There is. The vibration-proof panel 3 is constructed by sandwiching a vibration-proof material 3b such as compressed urethane between a pair of thin plywood 3a, and a sound-insulating sheet is interposed between the thin plywood 3a and the vibration-proof material 3b.

The cushioning material 5 arranged between the plywood 4 and the floor finishing material 6 is made of rubber mat, urethane mat or the like. The floor finishing material 6 laid on the cushioning material 5 is arranged so as to be adjacent to each other by connecting the male seeds 10 and the male seeds 11 provided at the ends of the plurality of panel bodies 6a. 1
Nail 9 is driven into the vibration isolating panel 3 from the connecting portion of 0 and the male 11, and the floor finish 6, plywood 4, and vibration isolating panel 3 are fixed by the nail 9.

The base plywood 2 placed on the joist 1 is connected and fixed to the joist 1 by nails 7. The plywood 4 and the vibration-proof panel 3 are connected and fixed by nails 8. Here, the anti-vibration panel 3 and the base plywood 2 are fixed to each other only with an adhesive, but the lower thin plywood 3a and the base plywood 2 that make up the anti-vibration panel 3 have a large contact area. Therefore, even if it is adhered by an adhesive, it can be sufficiently fixed.

However, the vibration on the floor finishing material 6 is not absorbed by the cushioning material 5 and the vibration isolating panel 3 and does not reach under the floor. The structure ensures that the vibration can be absorbed. Here, although the vibration on the floor finishing material 6 reaches the anti-vibration panel 3 by the nail 9, the anti-vibration panel 3 and the base plywood 2 are fixed by an adhesive and not fixed by the nail. Therefore, the vibration is surely absorbed by the vibration-proof material 3b that constitutes the vibration-proof panel 3, so that the vibration does not propagate from the vibration-proof panel 3 to the base plywood 2 and the joists 1 and the sound-proof performance is high. It has become a thing.

[0011]

As described above, according to the present invention, the base plywood is placed on the joist, and the anti-vibration panel constituted by interposing the vibration isolator between the pair of thin plywoods facing each other is mounted on the base plywood. Place the plywood on the anti-vibration panel, place the cushioning material on the plywood, place the floor finishing material on the cushioning material, and laminate and bond each member to each other with an adhesive The plywood is fixed to the joist with nails, the plywood is fixed to the anti-vibration panel with nails, and the thin plywood arranged on the upper part of the anti-vibration panel is driven from the upper surface of the floor finishing material with the fixing tool, and the floor finishing material,
Since the cushioning material, plywood and anti-vibration panel are fixed by nails, the vibration on the floor finishing material will be received by each panel and the cushioning material and anti-vibration panel, so that the vibration does not reach under the floor. Yes, that is, vibration on the floor finishing material reaches the anti-vibration panel by nails, but the vibration is damped by the anti-vibration material that composes the anti-vibration panel. Since it does not propagate, it is possible to reliably prevent the vibration from reaching the base plywood and joists and to enhance the soundproofing performance.
