Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for installing drainage facilities such as a sink, a sink, a bathtub, and a toilet in a multi-story apartment house.

[0002]

2. Description of the Related Art Conventionally, drainage facilities such as a sink, a wash basin, a bathtub, and a toilet in this type of apartment house have been installed at appropriate locations in a house, and especially in a part of the house. Did not. For this reason, the drainage pipes of these drainage-required facilities have been connected to drainage vertical pipes that penetrate each level through horizontal branch pipes.

In recent years, there has been an apartment house in which the entire area of each floor has an inverted beam floor structure for the purpose of storing plumbing pipes, wiring, and the like under the floor. In such an apartment house, there is an advantage that piping of drainage pipes of the respective drainage required facilities is very easy. However, when the entire area of each story has an inverted beam floor structure, each story height is a normal beam. It had to be about 60 cm higher than the floor structure. The drainage pipes of these drainage-required facilities were also connected to the drainage vertical pipes that penetrated each level through horizontal branch pipes, because the drainage-required facilities were not installed especially in a part of the house. .

[0004]

However, in the above-mentioned conventional apartment house, when it is desired to change the arrangement of each drainage equipment when the house is renovated or when the drainage equipment becomes obsolete and needs to be replaced, it is necessary to change the drainage equipment. It was necessary to redeploy the horizontal branch pipe connected to the drainage pipe of the drainage facility, which was troublesome and had a problem that the construction cost was high.

[0005] Furthermore, in the above-mentioned conventional apartment house in which the entire area of each story is an inverted beam floor structure, each floor height needs to be about 60 cm higher than a normal beam floor structure. However, there was a problem that it was disadvantageous and construction cost was high.

Accordingly, the present invention is to solve the above-mentioned conventional problems, and when it is desired to change the arrangement of each drainage required when the house is renovated, or when the drainage required is deteriorated and replaced, etc. An object of the present invention is to provide a structure for installing drainage-required equipment in an apartment house that can be easily performed without any trouble and that does not require high construction costs.

[0007]

Therefore, the installation structure of the drainage equipment required in the apartment house according to the present invention is such that the various drainage equipment U is integrated into a part of the house in each level of the apartment house 1, and these drainage equipments are installed. A drainage header 3 in which a drainage facility consolidation portion is constructed by projecting below each floor as a concave beam floor structure F, and a drainage pipe 2 of each of the drainage facilities U is connected to each underfloor space S formed by the concave beam floor structure F. And the drainage headers 3 are connected by drainage vertical pipes 4 penetrating each level.

Further, in the installation structure of the drainage required equipment in the apartment house according to the present invention, the drainage header 3 can be installed in each underfloor space S so as to be pivotable.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described.
This will be described in detail with reference to the drawings.

The figure shows a four-story apartment house,
At each level of the apartment house 1, various drainage facilities U
Are integrated in a part of the house (approximately in the center of the house in the figure), and these drainage-required facilities are formed as concave beam-floor structures F protruding down each floor. And
A drain header 3 to which the drain pipe 2 of each drainage equipment U is connected is installed in the underfloor space S below each floor formed by the concave beam floor structure F. Further, the drainage headers 3 below each floor are connected by vertical drainage pipes 4 penetrating through each level. In addition, it is preferable that the said drainage header 3 shall be installed in the underfloor space S of each floor so that it can swivel.

As the drainage required equipment U, for example, a sink U1
, Wash basin U2, bathtub U3, toilet U4, and the like. Normally, the sink U1, the washstand U2, and the toilet U4 are installed on the floor f of the concave beam floor structure F. However, in the bathtub U3, they are installed on the floor f of the concave beam floor structure F. A part thereof may be buried and installed under the floor surface f of the concave beam floor structure F.
By doing so, the height from the bathroom floor to the upper edge of the bathtub can be reduced, and the elderly and children can safely and easily take a bath.

The concave beam floor structure F is constructed by projecting a part of a normal beam floor 5 to each floor below, and a reinforcing portion is provided at a corner of the underfloor space S formed by the concave beam floor structure F. 6 are preferably provided. This reinforcement 6
As shown in FIG. 3, a metal bending form 7 is used, and a reinforcing brace 8 is buried inside the reinforcing portion 6 to have a strong structure. .

The drainage headers 3 are provided around the large-diameter body 9 around the connection ports 2a, 2b, 2
c ... and connection ports 4a, 4b of the drainage vertical pipe 4 at the upper and lower ends. The lower portion of the drainage header 3 is loosely fitted into the through hole 10 of the concave beam floor structure F, so that the drainage header 3 is installed so as to be pivotable in the underfloor space S.

In the present invention constructed as described above, since the concave beam floor structure F is constructed by projecting a part of the ordinary beam floor 5 below each floor, each floor height is the same as that of the normal beam floor structure. Can be height. In the present invention,
Although the ceiling height is low in the concave beam floor structure F, even if the drainage equipment U is concentrated in these parts, the drainage equipment consolidation part has a relatively small ceiling height because there are few people to move. In addition, there is no problem even when each drainage equipment U is used.

Further, in the installation structure of the present invention, when it is desired to change the arrangement of the drainage equipment U when the house is renovated, or when the drainage equipment is deteriorated and replaced, etc., each connection port of the drainage header 3 is required. 2a, 2b, 2c, etc., the drainage pipe 2 from each drainage required equipment U may be removed, and a horizontal branch pipe is not piped unlike a drainage pipe of a conventional drainage required equipment. You do not need to remove it. Then, the drainage pipe 2 of each drainage equipment U whose arrangement has been changed or replaced is again connected to each connection port 2a, 2b, 2c of the drainage header 3.
Just reconnect to ... When the drainage header 3 is installed in the underfloor space S so as to be swivelable, the drainage header 3 can be swung. The pipe 2 can be located at a position where it can be easily reconnected to the connection ports 2a, 2b, 2c... Of the drain header 3.

[0016]

According to the present invention, the installation structure of drainage equipment in an apartment house is constructed as described above, and each floor can have the same height as a normal beam floor structure. Buildings can be built without disadvantage even in areas where height restrictions are severe, and construction costs will not be expensive.

Further, the installation structure of the drainage equipment in the apartment house according to the present invention is troublesome when the arrangement of the drainage equipment is required to be changed at the time of renovation of a house or when the drainage equipment is deteriorated and replaced. However, it can be easily performed without cost, and the construction cost is not expensive.
