Substructure fabricated frame structure and construction method thereof

Abstract

The invention discloses a substructure fabricated frame structure and a construction method thereof. The substructure fabricated frame structure comprises a plurality of prefabricated frame pillar structures, a plurality of prefabricated frame beam structures and a plurality of prefabricated floor substructures; the prefabricated frame pillar structures are spliced longitudinally to form stand columns of a frame structure; in a main frame plane, the prefabricated frame pillar structures are horizontally spliced with the prefabricated frame beam structures through overhanging short beams; in ahorizontal perpendicular main frame plane, the prefabricated frame pillar structures are horizontally spliced with the prefabricated frame beam structures by embedding connecting steel bars at beam column joints; through holes are reserved in prefabricated frame pillar structure centers; and penetrating holes are reserved in two splicing directions of the beam column joints. The substructure fabricated frame structure has the advantages of being flexible and reasonable in prefabricated part types, simple and clear in assembly position internal force, reliable in position and being capable of improving the integral anti-seismic performance.

Description

technical field [0001] The invention relates to the technical field of prefabricated reinforced concrete frame structure house engineering, in particular to a sub-structure assembled prefabricated structure and a construction method thereof. Background technique [0002] At present, most of my country's prefabricated frame structure systems use beams and columns prefabricated in the factory, and then assembled and connected at the joints. The beam-column joints of the frame structure are complex and weak parts, which is not good for earthquake resistance. The steel bars at the beam-column joints are relatively dense. It is difficult to position and assemble precast beams and columns at the joints when the steel bars are staggered, and the traditional construction technology is used. The quality of construction at the seams is difficult to guarantee. In view of the above-mentioned deficiencies in the existing prefabricated reinforced concrete frame structure system and const...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the prefabricated frame structure systems in my country adopt the form of beam and column components prefabricated in the factory, and then assembled and connected at the joints. However, the beam-column joints of the frame structure are complex and weak parts, which are unfavorable for earthquake resistance.

The steel bars at the beam-column joints are relatively dense, and it is difficult to position and assemble precast beams and columns at the joints when the steel bars are staggered, and the traditional construction technology is used. The construction quality of the seams is difficult to guarantee
