Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a floor structure of a building.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Publication No.
There is one described in Japanese Patent No. 6376. What is described in this publication is a floor structure of a dwelling unit, which is arranged over the entire surface between floor beams and floor beams that form the floor surface, and supports the floor members through joists. The floor base plate (under floor plate in the above publication) is located at the bottom of the floor beam in the equipment room where the toilet, bathtub, etc. are arranged, and water is placed between the floor surface material and the floor base plate. An underfloor piping space in which surrounding piping can be arranged is provided.

[0003]

By the way, in the floor structure of the building described in the above publication, the floor base plates of the equipment room portion and the living room portion have the same thickness, and no consideration is given to the floor impact sound of the living room portion. Therefore, there is a problem that the floor impact sound is easily transmitted to the adjacent living part, particularly the lower floor part.

Further, in order to provide an underfloor piping space between the floor surface material and the floor base plate, the floor base plate of the equipment room portion is located at the bottom of the floor beam, and it is not necessary to provide an underfloor piping space in the living room portion. Since the floor base plate is located in the middle of the floor beam,
The structural problem that a torsional stress that is unfavorable to the floor beam is generated, and in the equipment room part, a receiving member with an L-shaped cross section is welded to the open side of the floor beam formed by the U-shaped channel material by welding or the like. Fix it and, in the living room, cross section T on the open side of the floor beam.
Since the V-shaped receiving member is fixed by welding or the like, there arises a problem that many constituent members are required to form the floor structure.

The present invention has been made in view of the above problems, and an object of the present invention is to reduce the floor impact sound of a living room portion without causing any disadvantageous stress to the floor beam.
It is to provide a floor structure of a building in which the number of constituent members can be reduced.

[0006]

[Means for Solving the Problems] To achieve the above object,

Immediately below each of the equipment room and the equipment room, the living room and the equipment room of the lower-floor dwelling unit, which have substantially the same plan, are arranged.

(Function) According to the floor structure of the building according to the first aspect of the present invention, the floor base plate of the living room is thicker than the floor base plate of the equipment room in which equipment around water is installed.
The floor impact sound generated on the floor surface material of the living room is blocked by the thickened floor base plate, and the floor impact sound of the living room can be reduced.

According to another aspect of the floor structure of the building of the present invention, the floor surface material of the equipment room portion is provided on the floor base plate of the equipment room portion via the floor support, and the floor surface of the equipment room portion is provided. Since the underfloor piping space capable of arranging the piping of the equipment is formed between the material and the floor base plate, it is not necessary to provide a receiving member on the floor beam as in the above-mentioned conventional technique, and the floor structure can be improved. Can be simplified.

According to the floor structure of the building of claim 3, the floor base plate of the living room portion and the floor base plate of the equipment room portion are supported on the upper surface of the floor beam. There is no generation of torsional stress, which is disadvantageous for floor beams. Further, since the floor surface material of the living room part and the floor surface material of the equipment room part are provided on substantially the same horizontal plane, there is no step between the living room part and the equipment room part, and the movement is easy. is there.

According to a fourth aspect of the floor structure of the building, the living room and the equipment room of the lower floor dwelling unit having substantially the same plane plan are provided directly under the living room and the equipment room of the upper floor dwelling unit, respectively. Since the parts are arranged, the impact sound generated in the living room portion of the upper-floor dwelling unit is blocked by the thick floor base plate, and the influence on the living room portion of the lower-floor dwelling unit immediately below can be reduced.
