1)を架設して構築するものである。(Conventional technology) The RPC (Ramen e-precast concrete) construction method has been used in the past, especially in high-rise buildings.
As shown in Figure 8, concrete PC (precast self-concrete) column material (50) and PC beam material (51)
At the same time, all PC pillars (50
), and then install PC beams (50) between the PC pillars (50).

の鉄筋量(本数)を増大し、配筋に必要な間隔を確保す
るために部材の断面積を大きくしている。In general, in the case of buildings with rigid frame structures, stress concentration occurs at the joints between beams and columns (arrow A), especially when using the RPC method.
The strength of a building is often determined by the bending strength of the ends of columns and beams. Therefore, when increasing the overall strength, the amount of reinforcing bars at the joints of the PC columns and beams (51) (number) and the cross-sectional area of the members is increased in order to secure the necessary spacing for reinforcement.

えない問題を有していた。Therefore, in the conventional RPC construction method, the cross-sectional area of the member increases due to the fit of the column reinforcement or beam reinforcement at the joint between the PC column material and the PC beam material, which reduces the effective space of the building and increases the Therefore, the jaw structure for supporting the beam had to be considered. In addition, in the conventional RPC construction method described above, the joint between the PC pillar material (50) and the PC beam material (51) is made of concrete cast on site, and the strength after construction is not stable depending on the construction condition. This had the problem that the cross section was larger and it was not necessarily economical compared to conventional construction methods.
本発明は上記問題に鑑みてなされたもので、接合部耐力
