Abstract

PROBLEM TO BE SOLVED: To improve heat insulation and waterproofness by setting a waterproof pan on the tile laying part of an upper story in which a room space exists in a lower story, and sticking tiles through a flexible foaming material on the waterproof pan. SOLUTION: A waterproof pan 24 is set on the tile laying part 2 of an upper story in which a room space exists in a lower story, and tiles 23 are stuck through a flexible foaming material 22 on the waterproof pan 24. A tile unit 20 sticking the tiles 23 through the flexible foaming material 22 on a base material 21 is previously formed in a factory, and may set on the waterproof pan 24. Therefore sounds generated on the tiles by walking are absorbed by the flexible foaming material 22, and do not transmit to the room space of the lower story. In addition, even in the case where water is spilled on the tiles 23 or the tiles 23 are washed by water, water leakage for the lower story is prevented by the waterproof pan 24.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound insulation structure of a building which is suitable for a case where a building has an entrance, a corridor, a veranda or the like on the upper floor of the building and a room space on the lower floor.

[0002]

2. Description of the Related Art Conventionally, the doors on the second floor of a building,
As described in JP-A-7-48917,
There are known a structure in which an integrally formed waterproof pan such as FRP is installed and tiles are attached to the waterproof pan, or a structure in which mortar is laid on a base plate and tiles are attached thereon.

[0003]

However, in the case where the finish is made of tiles as in the above-mentioned conventional door slap, there is a problem that shoe sounds affect the room space on the lower floor. For this reason, in the structure in which the waterproof pan is installed, the waterproof pan is made thicker, the structure is devised, the base material below the waterproof pan is made thicker, or a heavy thing is used. Further, in the structure in which the mortar is laid, the thickness of the mortar is increased, the underlying plate below the mortar is increased, or a heavy mortar is used. For this reason, there was a problem that the structure became complicated, the number of construction steps was increased, and the cost was increased.

Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide an excellent sound insulating property to a room on the lower floor, a low cost, and a low workability. It is to provide a sound insulation structure of a good building.

[0005]

According to a first aspect of the present invention, a tile is attached via a flexible foam material to a tile laying part on an upper floor having a room space on a lower floor. This is the sound insulation structure of a building.

According to a second aspect of the present invention, a sound insulation for a building according to the first aspect is provided in which a tile unit in which a tile is preliminarily attached to a base material via a flexible foam material is installed in the tile laying portion. Structure.

According to a third aspect of the present invention, a waterproof pan is installed on the tile laying portion, and a tile is attached to the waterproof pan via a flexible foam material. 2 is a sound insulation structure of the building described in 2.

In the present invention, the flexible foam material is a flexible foam material such as a synthetic resin foam or a rubber foam. The flexible foam material has an effect of absorbing the impact sound applied to the tile. The thickness of the flexible foam is preferably in the range of 1 mm to 5 mm. 1
When the thickness is less than mm, the effect of absorbing the impact sound is reduced. When the thickness exceeds 5 mm, the effect of absorbing the impact sound is large, but the walking feeling on the tile may be deteriorated. The expansion ratio of this flexible foam is preferably in the range of 5 to 40 times. If the thickness is less than five times, the effect of absorbing the impact sound is reduced. When the thickness is more than 40 times, there is an effect of absorbing the impact sound, but the walking feeling on the tile may be deteriorated.

The tiles used in the present invention include porcelain tiles, ceramic tiles, ceramic tiles, brick tiles, stone tiles, cement tiles, concrete tiles, and the like.
Wood tiles, plastic tiles, and the like are suitable, and the thickness thereof is preferably in the range of 2 mm to 40 mm. If it is too thin, the texture of the tile will decrease, and if it is too thick, it will be expensive.

[0010]

In the sound insulation structure of a building according to the first aspect of the present invention, a tile is attached via a flexible foam material to a tile laying part on an upper floor having a room space on a lower floor, so that the tile is generated by walking or the like. Absorbed sound is absorbed by the flexible foam material to prevent it from being transmitted to the lower room.

In the sound insulation structure for a building according to the second aspect of the present invention, a tile unit in which tiles are pasted on a base material through a flexible foam material in advance is installed in the tile laying portion. There is no need to attach tiles one by one on site, and workability is improved. In addition, since a tile can be attached to a base material via a flexible foam material at a factory equipped with mechanical equipment, the accuracy of tile installation is improved, and therefore, the performance of absorbing sound generated by the tile is also improved.

In the sound insulation structure for a building according to the third aspect, a waterproof pan is installed on the tile laying portion, and the tile is attached to the waterproof pan via a flexible foam material. When spilling or washing tiles,
The waterproof pan prevents water from leaking into the lower floor space.
