DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure for an apartment house such as an apartment.

[0002]

2. Description of the Related Art Conventionally, equipment pipes such as sewage pipes and drain pipes in apartment houses and the like have been penetrated through dwelling units arranged vertically. Therefore, there is a problem in that maintenance and renewal of the piping require construction in a dwelling unit of another resident.

[0003] In recent years, as a long-life apartment house, in order to obtain the freedom of layout and the like according to the generation change of the residents, etc.,
There has been proposed a skeleton-infer separation concept in which a skeleton (skeleton) and a part (infel) that can be changed as desired by a resident are separated. In such an apartment house, a horizontal plumbing is provided under the floor as a double floor structure. However, in such double-floor apartments, the height of the floor is high, and in areas where laws and regulations on the height of the whole building and shade are restricted, not only the number of floors that can be built is reduced, but also costs increase. Become. For example, the place where the floor height is normally about 2750 mm is required, but 3000 mm or more is required.

[0004] Further, it has been proposed to use the space in the floor slab (space generated by the void method or the like) for horizontal drawing pipes and wirings. However, since the diameter of a sewage pipe or a drain pipe is large, such a pipe is used. It is difficult to pass through the space. If you pass such a sewage pipe or drain pipe through the space in the floor slab,
There is a problem that the total thickness of the floor slab becomes too thick, which increases the cost and also increases the floor height.

The present invention solves such a problem, and does not require the construction of another resident in the dwelling unit for the maintenance of the piping, and provides a piping structure of an apartment house which enables piping without increasing the floor height. The purpose is to provide. Another object of the present invention is to provide an apartment house which does not require construction work in a dwelling unit of another resident for maintenance of piping while maintaining a general floor height.

[0006]

According to the piping structure of an apartment house according to the present invention, in a multi-story apartment house, a vertical piping space penetrating through each floor portion along a plurality of dwelling units arranged on the upper and lower floors is provided in a building frame. Provide in the common area. The floor slab of each dwelling unit is provided with a pit forming portion that projects in a beam shape on the lower surface of the floor slab and has a groove-like upper surface as a piping pit, extending from the vicinity of the installation part of the sanitary facility to the vertical piping space.
In the pipe pit, there is provided a horizontal pipe connected to the vertical pipe of the equipment pipe installed in the vertical pipe space and the sanitary equipment, and a cover is provided in the pipe pit. The common area is preferably, for example, a section facing a common hallway. According to this configuration, the vertical piping is installed in the common part, and the horizontal pulling piping of each dwelling unit is provided in the piping pit provided on the floor slab of the dwelling unit, so that the construction in another dwelling unit is unnecessary. . In addition, since the horizontal drawing pipe is arranged in a pipe pit with a grooved lid, maintenance of the horizontal drawing pipe can be easily performed by opening the lid. The pit forming part that formed the piping pit projects on the lower surface of the floor slab,
Since it only projects in the form of a beam, it only projects like a beam shape from the interior of the dwelling unit on the lower floor, and has little effect on the living space of the dwelling unit on the lower floor. Therefore, it is not necessary to increase the floor height.

In the above structure, the pit forming portion is
It may be provided along the boundary wall between adjacent dwelling units. In the case of this configuration, the protruding portion of the pit formation portion to the ceiling surface of the lower floor follows the boundary wall between the adjacent dwelling units, and thus only projects like a beam along the wall. Therefore, the pit forming part of the upper-floor dwelling unit is less likely to obstruct the living space of the lower-floor dwelling unit, and is less noticeable. Further, the pit forming section may be provided along a partition wall of a dwelling unit on a lower floor. Also in this configuration, the pit formation part of the lower floor dwelling unit obstructs the dwelling space of the lower floor dwelling unit because the overhanging part of the pit formation part to the ceiling surface of the lower floor follows the wall. Difficult
It is also hard to notice. Further, the pit forming portion may have a cross-sectional width corresponding to a corridor width. In the case of this configuration, the portion of the pit formation portion that projects to the ceiling surface of the lower floor becomes the ceiling portion of the corridor. In the corridor, even if the ceiling height is slightly lowered, there is little practical obstacle. Therefore, the pit forming part of the dwelling unit on the upper floor is unlikely to hinder the living space of the dwelling unit on the lower floor. Further, since the ceiling surface of the corridor becomes low over the entire width, the pit forming portion is inconspicuous. Further, the pit forming portion in the dwelling unit on each floor may be provided in a storage space where a storage room or storage furniture is installed. Since the storage space is difficult to use because the height near the ceiling is difficult for a human hand to reach directly, even if the ceiling height is slightly lowered, there is little effect. Therefore, by arranging the piping pits in the storage space in this manner, the pit forming portion can be provided with as little influence on the lower floor as possible.

[0008] An apartment house according to the present invention includes the piping structure having any one of the above-described structures according to the present invention, and has a floor height of 2650 to 2850 mm. Floor height is 275
It is most preferably about 0 mm, but there may be a difference of about 100 mm above and below. According to the apartment house of the present invention, the general 2650-2
While maintaining the floor height of 850 mm, it is possible to eliminate the necessity of construction in another dwelling unit for pipe maintenance.
