Connection process for bolt-type partially-clad concrete composite shear wall

Abstract

The invention relates to the field of buildings, in particular to a connection process for a bolt-type partially-clad concrete composite shear wall. In a factory, webs and wing plates are sequentiallywelded to form an I-shaped steel skeleton, first connection steel plates need to be welded on the wing plates according to design requirements, transverse shear wall limbs with the first connection steel plates are formed through pouring, second connection steel plates are welded to the portions, at side area grids, of the webs, longitudinal shear wall limbs with the second connection steel plates are formed through pouring, a plurality of connection holes are formed in the first connection steel plates and the second connection steel plates, the corresponding positions of the connection holes of the first connection steel plates and the second connection steel plates are calibrated multiple times during production, after transportation to a construction site, lifting and splicing are carried out to correspondingly arrange the first connection steel plates of the transverse shear wall limbs and the second connection steel plates of the longitudinal shear wall limbs, bolts oppositely penetrate through the connection holes for fastening, independent grids are formed, and cast-in-place construction is carried out. After the scheme is adopted, the key difficulties in production are solved, and the production and transportation cost is reduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a connection process of a bolt-type partially clad concrete composite shear wall. Background technique [0002] my country is vigorously promoting the transformation of traditional buildings to industrialized buildings. In traditional buildings, most of the work needs to be completed on the construction site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction personnel have become barriers to the progress of the construction industry. The partially clad concrete composite shear wall (PEC shear wall) is produced by an industrial production line. The concrete is directly poured into the semi-open cavity surrounded by the steel flange and the steel web. high speed. The out-of-plane stability of the in-line shear wall is weak, so the shear walls used in actual engineering are mostly L-shaped and T-shaped, so t...

AI Technical Summary

Problems solved by technology

The out-of-plane stability of the in-line shear wall is weak, so the shear walls used in actual engineering are mostly L-shaped and T-shaped, so that the wall limbs provide mutual out-of-plane constraints to ensure stability. This kind of special-shaped PEC If the integral prefabrication process of each wall pier is welded first and then poured at the splicing part of the combined shear wall, it will bring great difficulties to the pouring
