Rapid construction method for fabricated square beam-column joint

The invention discloses a quick construction method for a fabricated square beam-column joint. The quick construction method comprises the following construction steps: mounting a frame column, mounting a column cap, mounting a precast beam, binding beam-column joint steel bars, erecting a mold, pouring, removing the mold, and erecting the mold by adopting an air bag mold assembly. When the fabricated square beam-column joint is constructed, the air bag mold assembly is adopted for supporting the mold and the corresponding mold removal procedure, and therefore the mold is easy to manufacture and disassemble and can be conveniently and repeatedly used; especially, the air bag mold assembly has the following characteristics that the structural shape of a node is not changed, the whole body is resistant to deformation after being inflated, and the outer side can be reinforced through ribs; compared with the prior art, the formwork is simple in structure, light in weight, shaped and convenient to disassemble and
