接合部分の連続性に難点がある。In general, when a building is made of RC construction, many economic advantages can be expected compared to SRC construction, but there is a problem that the cross sections of columns and beams become larger, especially in high-rise buildings. For this reason, the increase in cross section can be suppressed by using high-strength reinforcing bars and concrete, but the economic benefits are reduced and quality control such as concrete mixing must be carried out adequately. In addition, with the PC method,
PC columns and PC beams need to be unified to a certain cross section from the point of view of mass production efficiency, and it is difficult to increase the types according to the cross section required by the building at the site.
Since c-beams are heavy, erection efficiency is lower than that of steel frame erection. Furthermore, in the PC construction method, there is a problem in the continuity of the joints and joints.

。Two layers of column PC members 2 are erected, and then column main reinforcements 5 and stirrups 6 are arranged on the outside of the PC members. Then, lift the PC member 8 of the beam, and
The PC member 8 is erected between the members 2 and 2, and both ends of the PC member 8 are supported on the PC member 2°2 using joint members, and the erecting is completed. In addition, the main beam reinforcement 11 and stirrup 1 of the PC member 8
2 is pre-assembled in advance at the factory or on-site. Of course, PC
After constructing the member 8, reinforcing bars 11 and 12 may be placed.
