Reinforced multi-cavity steel pipe and concrete shear wall and system and construction method

Abstract

The invention relates to a reinforced multi-cavity steel pipe and concrete shear wall and a system and a construction method. The reinforced multi-cavity steel pipe and concrete shear wall comprises amulti-cavity steel pipe and wall concrete, wherein the multi-cavity steel pipe is enclosed by a group of multi-cavity steel pipe monomers and end plates, and the adjacent multi-cavity steel pipe monomers are in butt welding; the horizontal section of each multi-cavity steel pipe monomer is in an I shape, and the multi-cavity steel pipe monomer comprises two multi-cavity steel pipe monomer units;the horizontal section of each multi-cavity steel pipe monomer unit is in a T shape, and the multi-cavity steel pipe monomer unit is cut by I-shaped beams or H-shaped steel or I-shaped steel; groovesare formed in the ends of webs of the multi-cavity steel pipe monomer units; the webs of the two multi-cavity steel pipe monomer units are in butt welding so as to form a vertical partition; and the grooves in the two multi-cavity steel pipe monomer units are correspondingly spliced so as to form a concrete flowing hole. According to the reinforced multi-cavity steel pipe and concrete shear wall,the technical problems of large difficulty in control over the construction quality, long construction cycle, poor fireproof performance, low construction speed, low tensile strength and poor seismicperformance of a traditional shear wall structure and poor ductility and easiness in brittle failure under the action of an earthquake are solved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a reinforced multi-cavity steel pipe concrete shear wall and its system and construction method. Background technique [0002] Building industrialization is the focus of construction development. At present, the mainstream structure of building industrialization is the prefabrication of some components, and the marginal area (node ​​area) adopts the system of cast-in-place shear wall structure; although this system has good construction integrity and low cost, It is economical and practical, and has good durability and fire resistance, but the construction quality control of this system is difficult, the construction period is long, the tensile strength is low, the seismic performance is poor, and the ductility is poor under earthquake action, and brittle failure is prone to occur . my country is a country with many earthquakes, and earthquake disast...
