Its perimeter is formed by four I-beams connected end to end to form a rectangular frame. The inner flanges of the I-beams are used to fix the horizontal and vertical distributed reinforcing bars of the precast wall panel. The web of the I-beams is equipped with double-sided stiffening ribs, and the outer flanges of the I-beams have bolt holes. On the construction site, the precast wall panels are spliced ​​together in pairs using high-strength bolts. After the precast wall panels are spliced, formwork is erected on the I-beam section and concrete is poured. This utility model has a clear concept, good overall performance, convenient splicing, and reliable performance, which is conducive to large-scale promotion and application.
