も利用できる。When the joining is completed, another steel pipe column is added to the steel pipe column 2 and a PC beam is bridged between these steel pipe columns, and the joint end is connected to the steel pipe column in the same manner as described above. (Not shown), and this is sequentially repeated to construct a building. As described above, since the steel pipe column 2 is lightweight at the time of building, there is no restriction on the lifting capacity of the hoisting machine, and after the concrete is built, the concrete 4 is cast into the steel pipe column 2 to increase the strength. It can also be used for building high-rise buildings to increase the number.
