Reinforced type prefabricated steel bar concrete shear wall, structural system and construction method thereof

Abstract

The invention relates to the technical field of structural systems of shear walls, and discloses a reinforced type prefabricated steel bar concrete shear wall, a structural system and a construction method thereof. The reinforced type prefabricated steel bar concrete shear wall is composed of a prefabricated wallboard connected from up to down, and comprises reinforced vertical steel bones, steel bars and poured concrete wall bodies, wherein the reinforced vertical steel bricks and steel bars are located in the edge area of the prefabricated wallboards. The vertical steel bones are arranged discontinuously and are arranged at the connection nodes of the upper and lower ends of the prefabricated wallboards; edge longitudinal bars are fixed by horizontal hooped reinforcements or tie bars and arranged outside the reinforced vertical steel bones in a sleeved mode. The outer sides of the reinforced vertical steel bones are connected with the edge longitudinal bars in a lapped, anchored or welded mode, one end extends out of the concrete walls; the height of the concrete walls is not higher than the height of the edge longitudinal reinforcements and wall body vertical steel bars; the upper and lower adjacent prefabricated wallboards are connected by the corresponding reinforced vertical reinforcements, edge longitudinal reinforcements and walls body vertical steel bars, and connecting gaps are poured at the connection nodes. The reinforced type prefabricated steel bar concrete shear wall, the structural system and the construction method thereof have the advantages of being low in cost and convenient in construction; having excellent shear strength at the connections; being convenient to control the construction quality.

Description

technical field [0001] The invention relates to the technical field of shear wall structural systems, in particular to a reinforced prefabricated reinforced concrete shear wall, a structural system and a construction method thereof. Background technique [0002] The industrialization of construction is the focus of national construction and development. In the "Several Opinions of the Central Committee of the State Council on Further Strengthening the Management of Urban Planning and Construction" issued on February 6, 2016, it is clearly pointed out that "vigorously promote prefabricated buildings" and "encourage construction enterprises to assemble construction, on-site assembly", "building a national-level prefabricated building production base", "increasing policy support, and striving to make prefabricated buildings account for 30% of new buildings in about 10 years". [0003] my country is a country with frequent earthquakes. Earthquake disasters are the natural disast...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved is: the existing prefabricated building adopts the cast-in-place shear wall structure system in the edge component area or node area, the construction volume is large, the construction quality is difficult to control, the construction period is long, the steel consumption is large, and the tensile strength is high. Low strength, poor seismic performance, poor ductility, prone to brittle failure
