[0028]

As described above, according to the present invention,
The partition wall for the storage unit is made of pre-cast factory-produced self-sustainable pre-cast, and it is installed in a predetermined place, and the formwork is placed on the ceiling part of it. It is possible to easily construct a small common vertical pipe storage unit in a narrow space with the easy work of placing concrete for ceiling slabs and corridors.

Thus, as in the conventional case, a large number of small and large molds are manufactured and processed, and the molds are arranged in a narrow space for bar arrangement, and the mold is removed after the concrete is poured. This frees you from the troublesome and time-consuming work and, in the end, shortens the construction period and reduces the construction cost.

In this case, if not only the partition wall but also the ceiling part is integrally made of precast, the construction period can be further shortened. Since the position is designed according to the scale of the building, etc., if this is also made of precast, the number of designing and manufacturing steps will be doubled and the manufacturing cost will be high. Only the partition walls are made of precast, and the ceiling part is used as a formwork, thereby further reducing the cost.

That is, in the present invention, with emphasis on reduction of construction cost, the ceiling portion of the common vertical pipe insertion portion, which has a different thickness and arrangement position for each building, is made to correspond to the thickness and arrangement position of the common vertical pipe. Taking the construction means by the formwork provided with the cylinder,
Only the partition walls of at least two wall surfaces that form the shared vertical pipe storage section are made of three-dimensional self-supporting precast, and these are integrated with the building by concrete.
