Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a floor sound insulation structure for a building.

[0002]

2. Description of the Related Art In a building such as an apartment house, a floor material vibrates due to an impact on a floor material caused by movements such as walking upstairs, opening and closing doors, moving furniture, etc. It is a problem to make them.

This floor impact noise is reduced by increasing the thickness of the floor material and increasing the density of the floor material, but the thickness and the density of the floor material are limited, and sufficient countermeasures cannot be taken. For this reason, conventionally, as described in JP-A-4-238935, a plurality of ceiling hanging trees are arranged in parallel between the floor beams supporting the floor material on the floor, and the ceiling hanging trees are attached to these ceiling hanging trees. The ceiling material is hung and supported through the field edge, and a weight is attached to a ceiling hanging tree located in a portion of the floor structure where the vibration is great, or as described in Japanese Utility Model Publication No. 62-8265. The ceiling slab installed on the floor was hung and supported via a ceiling vibration-proof elastic member consisting of a vibration-proof rubber and a pair of support plates to provide sound insulation measures.

[0004]

However, in the former floor sound insulation structure, although the vibration of the ceiling material can be suppressed by the weight, when the span between the floor beams increases, the length of the ceiling hanging tree also increases. As a result, the vibration of the ceiling material also increases, so there was a problem that a sufficient sound insulation effect could not be expected with the weight alone.

Further, in the latter floor sound insulation structure, when a shock is applied to the floor, the vibration of the ceiling material can be suppressed by elastic deformation of the ceiling vibration-proof elastic member. Although the span does not increase the vibration of the ceiling material, in order to improve the sound insulation effect, it is necessary to increase the vibration damping rubber of the ceiling vibration damping elastic member, so the space between the floor material and the ceiling material is narrow. There was a problem that it was not suitable for buildings like.

In view of the above problems, it is an object of the present invention to provide a floor sound insulation structure that exhibits a high sound insulation effect even in a building where the space between the floor material and the ceiling material is narrow.

[0007]

In order to achieve the above object, in the floor sound insulation structure according to the first aspect of the present invention, the ceiling material is composed of a plurality of ceiling panels, and each of the ceiling panels is located above the floor. The floor structure that supports the floor material installed in the above is suspended and supported via the ceiling vibration isolation elastic member, and the inter-panel vibration isolation elastic member is interposed between each ceiling panel. Further, in the floor sound insulation structure according to claim 2, the ceiling vibration-damping elastic member is composed of a pair of support plates arranged in parallel and a vibration-damping rubber interposed between the support plates. One of the support plates is fixed to the floor structure in a substantially vertical state, and the other of the support plates is fixed to the ceiling panel in a substantially vertical state.

[0008]

In the floor sound insulation structure according to the first aspect of the present invention, when an impact is applied to the floor material, not only the vibration of the ceiling material is suppressed by elastic deformation of the ceiling vibration-proof elastic member but also the inter-panel insulation is prevented. Vibration of the ceiling material is also suppressed by elastically deforming the vibrating elastic member. Moreover, since the inter-panel anti-vibration elastic member is provided between the ceiling panels constituting the ceiling material, it can be installed regardless of whether the space between the floor material and the ceiling material is wide or narrow.

Further, in the floor sound insulation structure according to the second aspect of the present invention, when the floor material is impacted, the vibration damping rubber of the ceiling vibration damping elastic member is elastically deformed in the shearing direction. In other words, the vibration-proof rubber is deformed more than when the vibration-proof rubber having the same hardness and the same size is compressed and stretched.
Vibration of the ceiling material is reliably suppressed.

The elastic caulking material 6 is mounted in the gap between the ceiling panels 41, 41 after the ceiling panel 41 is attached and installed with a predetermined gap.

Since the floor sound insulation structure of the first embodiment is constructed as described above, when the floor material 1 is impacted, the vibration-proof rubber 53 of the ceiling vibration-proof elastic member 5 is elastic in the shearing direction. Not only the vibration of the ceiling material 4 is suppressed by the deformation, but also the vibration of the ceiling material 4 is suppressed by the elastic deformation of the elastic caulking material 6 as the inter-panel vibration-proof elastic member. The vibration-proof rubber 53 of the ceiling vibration-proof elastic member 5 is elastically deformed in the shearing direction and is deformed more than when the vibration-proof rubber having the same hardness and the same size is compressed and stretched.
