DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure for a unit building constructed by connecting a plurality of building units.

[0002]

2. Description of the Related Art When connecting a plurality of building units to form a piping structure of one unit building, it is sometimes necessary to use a facility building unit in which a water tubing facility such as a bathtub, a washbasin, a toilet, and a sink is previously installed. Much has been done.
By the way, such piping from the hot or cold water source to the plumbing system was generally performed after the building unit was installed at the construction site, but the piping work must be performed in a narrow underfloor space. And the work efficiency is poor. Therefore, in recent years, a method has been proposed in which a header is attached to the floor of a building unit in a factory, and piping between the header and the plumbing system is also performed in advance (Japanese Patent Laid-Open No. 2-61264). Gazette).

[0003]

However, even in such a conventional unit building piping structure, one end of the piping of the plumbing system cannot be connected to the header attached to the floor of the building unit at the factory. There are cases. In other words, there is a case where there is another equipment unit provided with a water supply facility in addition to the equipment building unit to which the header is attached. In this case, piping of equipment building units without headers must be performed across building units after the building units are installed at the building site, which takes the same labor as before. was there. Therefore, the present invention is aimed at improving the plumbing workability in a unit building, focusing on the above problems.

[0004]

In order to achieve the above object, according to the present invention, in a unit building having a plurality of plumbing units each having plumbing facilities therein, A piping structure between a water tap and a water source of a plumbing system, wherein an outer header connected to a water source is provided under the floor of the building unit, and a pipe connected to the faucets of the plurality of plumbing units. Is connected to the outer header.
In the invention described, an inner header is provided in the building unit, and a pipe connected to each faucet of the plurality of plumbing units is configured to be connected to the outer header via the inner header. . Here, the header may be a pipe branching means having a plurality of branch ends.

In the invention according to claim 3, a hot water supply branch connected to a water source via a water heater and a water supply branch connected to a water source without the water heater are provided. A pipe connected to a faucet of a plumbing facility that uses both hot water and water is connected to a pair of hot water supply pipes and a water supply pipe via a valve, and the hot water supply pipe is connected to the hot water supply branch. Along with this, the water supply pipe is connected to the water supply branch, and valve switching control means for switching the valve between a water supply side and a hot water supply side is provided, and the valve switching control means can be operated from a faucet operation area. Wherein the faucet is a single faucet.
A pipe connected to a faucet of a plumbing system that uses both hot water and cold water is connected to a water heater via a hot water supply branch, and a water temperature setting means for setting a temperature of hot water supplied from the water heater is provided. The water temperature setting means is operable from a faucet operation area, and the faucet is a single faucet.

[0006]

According to the first aspect of the present invention, the pipes are connected to the water taps of the plumbing facilities of all the equipment building units in the factory, one end of the pipes is guided under the floor, and the building units are fixed at the construction site. Then, by connecting one end of the pipe to an outer header provided under the floor of the building unit, the pipe from the water source to the plumbing system can be completed.

According to the second aspect of the present invention, an inner header is previously installed in a building unit in a factory, one end of a pipe is connected to the inner header, and after the building unit is installed on a building site, By connecting the inner header to the outer header, the piping from the water source to the plumbing equipment can be completed.
