It is possible to increase the supply amount to each floor X (X1 to X6) by increasing the number of pipes 30 piped to X (X1 to X6).

As described above, the piping wall units 10A and 10B forming the wall 5 of the building 1 are vertically stacked so that each floor X (X1 to X6) of the building 1 is
Since the sheath pipe assemblies 14 that are vertically connected to each other can be arranged with the same floor such as the uppermost 6th floor X6 as a reference position, each sheath pipe assembly 14 can be used as a guide for each floor X.
The pipe 30 can be provided at (X1 to X6). Therefore, since the pipe 30 can be piped as a vertical pipe in the wall 5 of the building 1, it can be piped into each room in a form branched from the pipe 30 in each floor X (X1 to X6), and piped in the building 1. Therefore, the floor area of the building 1 does not require the area for providing the pipe shaft as in the conventional case. Therefore, in a building such as the building 1, it is possible to pipe without reducing the effective floor area that can be used for the original purpose of forming a living room, an office, and the like. That is, since the pipe 30 can be installed as a vertical pipe in the wall 5 of the building 1, the pipe wall unit 10
Can be provided in any way as long as it forms the wall 5 of the building 1, so that the degree of freedom in the position where piping can be made in the building 1 is higher than in the past, and the floor plan of each floor X of the building 1 The degree of freedom of Furthermore, by making it possible to connect the pipe 30 that becomes a vertical pipe to each floor X of the building 1,
Even if it is necessary to replace the pipe piped in the building 1 with a new pipe due to a problem such as breakage, it is only necessary to replace the defective pipe with a new pipe and renew it. It is easier than updating the main pipe or the like that is the main pipe shared by each floor X. Further, by installing the pipe wall unit 10, the wall 5 of the building 1 is formed, and by preparing to be able to pipe the pipe 30 that serves as a vertical pipe to each floor X of the building 1, the work process is shortened. In addition to the actual piping work by the plumber,
It is only necessary to concentrate after the formation of the building, and it is not necessary to perform the piping work in the form of being cut between the building construction as in the past, so piping work can be performed efficiently and economically in a short period of time. You can

As another example of the in-wall piping structure, by setting the diameter of the pipe 30 to the maximum diameter that can be piped in the wall space 11b of the piping wall units 10A and 10B, In the case where the required number of pipes 30 cannot be installed in the wall space 11b, for example, 9 shown in FIG.
