Both the upper prefabricated block and the lower prefabricated block are provided with a plurality of through holes, and the edges of the upper prefabricated block and the lower prefabricated block are welded or screwed to the reinforcement cage of the prefabricated column. The beam-column prefabricated components are poured with concrete and steel cages, and the upper and lower prefabricated blocks are poured together with the beam-column prefabricated components, so when pouring, concrete will also be poured into the upper and lower prefabricated blocks In the through hole of the concrete section, the weakening of the concrete section is reduced; the upper prefabricated block and the lower prefabricated block are generally made of steel, and the edges of the upper prefabricated block and the lower prefabricated block can be welded on the steel cage, or the upper precast block The edge of the edge and the edge of the lower prefabricated block are screwed on the steel cage.

This method can ensure the quality of the project, shorten the construction period, save building materials and be environmentally friendly, meet the requirements of building industrialization, and realize the failure mode of strong columns and weak beams in frame structures. In the traditional frame structure, the beam and the floor are integrally poured together. This form increases the stiffness of the beam a lot, making it difficult for the frame structure to achieve the failure mode of strong columns and weak beams. In the present invention, the beam-slab prefabricated components are connected together with the prefabricated beams through connecting components, and the number of connecting components can be determined according to the realization needs. Through the form of connecting components, the connection between the floor slab and the beams is weakened, and a strong The purpose of column weak beam.
