Description

Technical Field

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. When connecting and fixing precast beams and columns in precast concrete buildings, prefabricated concrete beam-column joint connection structures are required.

[0003] The prior art discloses a precast assembled building concrete beam-column steel composite connection node structure with publication number CN213926777U, including precast columns, precast beams, and connecting components. The precast columns have internal fixing ribs, one end of which extends beyond the column. A steel plate is welded to the side of the precast column. The precast beams have through-type steel sections, one end of which extends beyond the beam. A protrusion is located below the protruding end of the steel section. The connecting components include a cast-in-place upper part and a precast lower part. The cast-in-place upper part is a hollow pre-reserved groove, and the precast lower part has a groove matching the protrusion on the side away from the precast column. When the groove and protrusion are completely closed, a buffer gap is formed. This utility model improves the assembly speed and reduces construction costs while ensuring safety and stability during the assembly process. It also improves seismic performance. The overall design is simple, has good seismic performance, is convenient to construct, and has high assembly efficiency, making it of practical significance.

This results in irregular shapes for the precast columns and beams, affecting their transportation and consequently impacting the construction efficiency of precast buildings. Furthermore, the beam-column joint connection structure requires workers to tighten multiple toothed bolts and fix angle steel during installation, making the construction process relatively complex and its practicality somewhat limited.
