た。(Conventional technology) When constructing conventional reinforced concrete shear walls,
For the walls, along with the outer columns and beams, reinforcing bars were assembled at the construction site, formwork was erected, and concrete was poured from the upper floor through the beams.
（発明が解決しようとする問題点）
従つて前記従来の施工方法では鉄筋を組立てる

定せず、コンクリートのひび割れの惧れもある。 In addition, in terms of construction accuracy, errors in manufacturing and erection of formwork occur, reinforcing bars tend to come into contact with formwork, and reinforcing bars tend to become disordered. Furthermore, the reinforcing bars become disordered when concrete is poured, and the finish on the concrete pouring surface varies depending on the concrete mixture, pouring method, and curing direction, and there is a risk of cracking of the concrete.
このように前記従来の施工法では、多大の手間

It is built in a structure composed of beams, and after connecting each kotta of the wall slab and the kotsuta reinforcement that protrudes from the kotsuta opposite to the same wall slab of the wall slab and beam, the space between the wall slab and the columns and beams is connected. This relates to a method of constructing a precast reinforced concrete shear wall, which is characterized by pouring bonded concrete into the walls.

The kotta of the wall slab and the kotsuta reinforcements of the wall slab, columns, and beams that protrude from the kotsuta provided on the opposing surfaces of the columns and beams are joined, and joint concrete is poured between the wall slab and the columns and beams. As a result, the wall slabs are rigidly connected to the columns and beams by the cotter reinforcement joints and the joint concrete filled in each cotter, ensuring the transmission of stress between the columns, beams, and wall slabs.

向上される。 Therefore, in the present invention, precast reinforced concrete wall slabs manufactured in a factory are installed inside columns and beams using cranes, etc., without assembling reinforcing bars, erecting formwork, or pouring concrete at the construction site. Construction is significantly simplified by joining the kotsuta reinforcements of the wall slabs, columns, and beams, and placing joint concrete between the wall slabs, which have kotsuta on the opposing surfaces, and the columns and beams. This reduces the number of workers on site, reduces the number of industries, simplifies and shortens processes, makes the workplace more orderly, and improves the working environment.
