CONSTITUTION: A pipeline 16 with one end connected to a wash stand 14 or the like is led under a plurality of sleepers 5 forming a floor 1, thereby eliminating the need of forming a notch on the sleepers 5 when the pipeline 16 is laid thereon. In addition, the pipeline 16 is supported on the sleepers 5 at a plurality of positions, thereby ensuring the pipeline 16 to be fixed to the floor 1. Furthermore, the sleepers 5 are made of metal, and the strength of the floor 1 becomes high, even when the height of the sleepers 5 is small. As a result, a piping size under the floor 1 can be enlarged. Also, the pipeline 16 is factory mounted on the sleepers 5 and, therefore, a piping work at the construction site can be lessened. In this case, a piping work becomes easy without any need for a worker to stay under the floor 1 by inverting the floor 1 in upper and lower positions and restoring the floor 1 to an original state after piping. According to this construction, piping work efficiency can be improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure of a building unit which constitutes a unit type building.

[0002]

[Background Art] In order to shorten the construction period at the construction site, multiple building units manufactured at the factory are transported by truck to the construction site, and at the construction site, a plurality of building units are combined to construct a unit-type building. There is. In this unit type building, water supply facilities such as a washbasin, a toilet, a washing machine, and a system kitchen are arranged on a floor section that is constructed by attaching floor coverings to multiple wooden joists. . The drainage discharged from each water supply facility is concentrated and discharged to the main pipe through a pipe arranged under the floor of the building unit, or is supplied from the main pipe to the water supply facility through the pipe.

For this reason, it is necessary to carry out piping work for installing the piping under the floor of the building unit, and conventionally, this piping work has been carried out at the construction site. However, in order to shorten the construction period at the construction site, it is desirable to carry out the piping installation work at the factory. In this case, since the pipes are arranged along the lower surface of the flooring material, the notches are formed in the plurality of joists,
It is conceivable to fit a pipe into this notch.

[0004]

In the structure in which the pipe is fitted into the cutouts formed in the lower part of the plurality of joists, the work of forming the cutouts is indispensable during the installation work of the pipes. Since the cutout must be formed at a predetermined position of each joist, the work of forming the cutout becomes complicated and the pipe installation work becomes inefficient.

It is an object of the present invention to provide a piping structure for a building unit in which piping can be installed without forming a cutout in the joist.

[0006]

Therefore, the present invention is intended to achieve the above object by passing a pipe under the joists forming the floor of the building unit. In particular,
The piping structure of the building unit of the present invention is a piping structure of a building unit that constitutes a unit-type building, and a water supply facility is arranged on the floor, and the floor of the building unit includes joists. It is characterized in that a pipe having one end connected to the water supply facility is passed under the joist.

Here, the pipe may be attached to the lower surface of the joist. The joists may be made of metal. Furthermore, the piping may be attached to the joists of the building unit in advance in a factory.

[0008]

In the present invention, a floor unit is manufactured from joists or the like in a factory, and a wife unit and a ceiling unit are attached to the floor unit to manufacture a building unit. A plurality of these building units are manufactured, and a water supply facility is arranged on the floor of a predetermined building unit among them. These building units are transported to the construction site by truck, and at the construction site, a plurality of building units are combined on the foundation to build a unit-type building. Plumbing work will be performed on a predetermined building unit among these building units. That is, by effectively utilizing the underfloor space of the building unit, the pipe is passed under the joist, and the water supply equipment arranged on the floor is connected to the end of the pipe. Since the pipe is passed through the bottom of the joist of the building unit, it is not necessary to form a cutout in the joist when installing the pipe.

Here, if the pipe is attached to the bottom surface of the joist, the pipe is securely fixed to the floor. Further, if the joists are made of metal, the strength of the floor can be increased even if the height of the joists is short, so that a large piping space under the floor can be secured. On the other hand, when the joists are made of wood, the height of the joists becomes large in order to secure the strength of the floor, and there is a case where the piping space under the floor cannot be sufficiently secured. Furthermore, if the piping is attached to the joists of the building unit in advance at the factory, the piping work at the construction site can be shortened.
