られる。According to this invention, after the PC beam 3 for installing the curtain wall is erected and fixed to the steel beam 4 of the N+1 floor of the building, and the formwork 5 for concrete construction of the N floor is assembled, the PC beam 3 for installing the curtain wall is assembled. Since the curtain wall 6 of the N+1 floor is attached to the PC beam 3 and then the concrete structure is poured into the formwork 5, it is necessary to install the curtain wall 6 before constructing the building frame. It is possible to omit fall prevention measures such as a fall prevention net around the outer periphery of the building, and by fixing the primary fastener 1 for curtain wall attachment by punching the PCC 10 when manufacturing the PC beam 6 for curtain wall attachment at the factory. , the installation accuracy of the primary fastener 1 can be improved, and since there are no obstacles such as beams above the curtain wall installation part, the installation work of the curtain wall 6 can be easily carried out, and moreover, it can be done at the construction site. There is no need for external scaffolding for reinforcing beams for installing curtain walls or assembling formwork, and the PC beams 3 for installing curtain walls have greater rigidity than steel beams for installing curtain walls.
Effects such as fewer errors when adjusting the curtain wall can be obtained.
