The third aspect stipulates an example of a method of incorporating the piping equipment unit of the present invention into the building frame at the stage where the open corridor is formed. In this case, it is necessary to form vertical through holes corresponding to the sectional shape of the piping equipment unit in the open corridor on each floor. The connected body of the piping unit is
After being lifted high, the through holes are inserted from top to bottom.

Whichever construction method is adopted, it is not necessary for a worker to enter a narrow pipe space and perform a complicated piping work as in the conventional method, which greatly reduces the construction period of a building. Contribute.

Further, the pipe facility unit of the present invention is arranged in the open corridor with the outer wall of the dwelling unit as the back when it is attached to the building frame. Therefore, the back surface of the housing can be left open, and the open back surface can be closed by the outer wall of the dwelling unit. Then,
The number of members for the housing is small, the volume and weight of the unit can be reduced, which is further advantageous in terms of both member cost and transportation cost.

Further, the housing is generally formed by combining refractory lightweight concrete boards. Therefore,
After this plumbing unit is assembled to the building frame,
The same treatment as the outer wall treatment of the building frame can be continuously performed by extending the outer wall of the housing of the unit. Therefore, when the building is completed, the piping equipment unit looks as if it is an integral part of the building skeleton, and compared to adopting a method such as covering the piping space with a sheet metal cover, for example. The appearance of the building itself can be improved, giving it a luxurious feel.
