When assembling a prefabricated house, first, the wall box 6 is fitted and fixed in the accommodating recess 5 of the rectangular body 1, and then the required pipeline 10 is piped so that it can be connected to the unit bath 2 through the through hole 8. However, after this piping is completed, the troublesome construction procedure of arranging the unit bath 2 adjacent to the rectangular body 1 has to be taken, and there is a disadvantage that it takes a long time to assemble a prefabricated house. .

Further, in a prefabricated house manufacturing factory, the rectangular body 1 into which the wall box 6 is fitted and fixed and the unit bath 2 are integrally incorporated, and the pipe connection between the water heater 4 and the unit bath 2 is connected to the site of prefab assembly later. In the case of the above, it is necessary to bend the pipe line 10 extending horizontally from the bathtub 3 in the standing direction and project it to the accommodation recess 5 side through the through hole 8, and this piping work is performed by the unit bath 2 and the rectangular body 1. The gap 12 between and is very narrow, and it is almost impossible to work from the inside. Therefore, in the installation structure of the conventional water heater 4, the unit bath 2 and the rectangular parallelepiped 1 in which the wall box 6 is fitted are prefabricated. Considering the difficulty of the piping work in the field, it is almost impossible to integrate it at the manufacturing factory of the house,
As described above, the wall box 6 is fitted into the accommodation recess 5 of the rectangular body 1, and then the pipeline 10 is incorporated through the through hole 8 for piping, and then the unit bath 2 is attached locally. Not only that, there was a problem not only in the production efficiency of the prefabricated house, but also in the local assembly work, which was a drawback.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to enable prefabricated manufacturing by making it possible to integrally construct a rectangular body incorporating a wall box and a unit bath in a prefabricated house manufacturing factory. In addition to improving efficiency, it also facilitates on-site piping work in the post-process of the unit bath and water heater, and provides a water heater installation structure in prefabricated houses that can significantly reduce the construction period for prefabricated house assembly. To do.

The present invention is configured as follows to achieve the above object. That is, in the installation structure of the water heater in the prefab house of the present invention, the rectangular body adjacent to the unit bath is projected to the unit bath side, and the accommodation recess for accommodating the water heater is extended to the lower position of the unit bath. The water heater is accommodated on the upper side of the accommodating recess, and the through hole communicating with the unit bath is formed on the lower side of the accommodating recess, and the conduit connected to the unit bath through the through hole is rectangular. Is horizontally piped from the outside of the unit bath into the unit bath, and the pipe line on the outside of the rectangular body is almost vertically raised in the accommodating recess exiting the through hole from the unit bath and connected to the water heater. It is characterized by being present.

[Action]

In the present invention, since the accommodating recess of the water heater formed in a rectangular shape is extended to the lower position of the unit bath, a hole for passing a pipeline is formed in the side wall of the accommodating recess at the lower position of the unit bath. By utilizing this, the conduit on the unit bath side is brought out to the outside accommodation recess, and by bending the conduit from the lower position of this accommodation recess in the standing direction, the connection with the water heater can be easily performed outside the rectangular body. It will be possible.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
In the description of the present embodiment, the same members as those in the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 1 is a sectional view showing an embodiment of a water heater installation structure in a prefabricated house according to the present invention, and FIG. 2 is a front view of the water heater installation structure. There is. The present embodiment is different from the above-mentioned conventional example in that the accommodation recess 5 provided in the rectangular body 1 is sufficiently extended to the lower position of the unit bath 2 and is vertically provided. In this embodiment, the rectangular body 1 and the unit bath 2 are provided on the floor surface 11 of the prefabricated house.
And are integrally manufactured in a prefabricated house manufacturing plant. A through hole 8 is formed in the side wall of the rectangular body 1 and the wall box 6 located on the lower end side of the accommodating recess 5, and a required pipeline 10 is horizontally passed through the through hole 8. One end of the pipe 10 is bent upward from the lower end of the accommodating recess 5 at a substantially right angle and connected to the water heater 4, and the other end of the pipe 10 is guided to an appropriate position.
It is connected to the unit bus at a predetermined position.

As described above, according to the present embodiment, since the accommodating recess 5 is extended to the lower position of the unit bath 2, the pipe line 10 is horizontally oriented by utilizing the through hole 8 provided at the lower end position of the accommodating recess 5. The wall box 6 can be fitted and fixed because the rising bent portion for connecting the water heater 4 can be formed outside the rectangular body 1, that is, at the lower end position inside the accommodation recess 5. Even when the rectangular body 1 and the unit bath 2 are unitized into an integrated structure, the pipe 10 can be easily inserted by inserting the pipe line 10 from the outside through the through hole 8 into the pipe, and the pipe with the unit bath 2 can be easily connected.

Since it is configured to be piped horizontally, when piping between the inside of the unit bath and the outside of the rectangular parallelepiped, the pipeline should be from outside the rectangular parallelepiped into the unit bath or from inside the unit bath outside the rectangular parallelepiped. Since it suffices that the through hole be made horizontal, the piping work becomes extremely easy. Further, since the pipe and the water heater can be connected to each other by raising the pipe almost vertically in the accommodating recess and guiding it to the water heater, this connecting work can be performed outside the rectangular body. It will be very easy. In this way, both the pipe connection between the inside of the unit bath and the outside of the rectangular body and the pipe connection to the water heater can be facilitated, so that it is possible to greatly reduce the construction period of the prefabricated house. Of course, after-sales service work such as replacement of these piping lines can be easily performed.

Even when the rectangular body having the wall box built into the accommodation recess and the unit bath are integrated into a unit structure, the pipe connection work of the water heater and the unit bath at the site, that is, the inside of the unit bath and the rectangular bath is performed. Piping work between the outside of the body and piping work between the pipeline and the water heater become very easy. In this way, even with the unit configuration, there is no difficulty in on-site piping work in the conventional example, so it is possible to proceed with unitization without worrying about the difficulty of piping work. Since the rectangular box with this wall box and the integrated unit of the rectangular box and the unit bath can be installed in the prefabricated house manufacturing factory, the manufacturing efficiency of the prefabricated house is dramatically improved and the prefabricated house is improved. It is possible to further improve the shortening of the assembly period.
