Fully assembled steel pipe concrete frame composite shear wall structure

Abstract

The invention provides a full assembly type steel pipe concrete side frame combined shear wall structure, which comprises a steel pipe concrete post, a prefabricated shear wall and a floor slab, wherein the steel pipe concrete post comprises a steel pipe post and post wall connecting sectional steel welded on the periphery of the steel pipe post; concrete is cast in the steel pipe post; a plurality of screw bolt holes are formed in two sides of the post wall connecting sectional steel, and are used for connecting the prefabricated shear wall; the prefabricated shear wall comprises a reinforced concrete shear wall and embedded sectional steel positioned on the periphery of the reinforced concrete shear wall; a plurality of screw bolt holes are formed in the left side and the right side of the embedded sectional steel, and are used for connecting the post wall connecting sectional steel or the embedded sectional steel of the other prefabricated shear wall; the upper side and the lower side of the embedded sectional steel are provided with end plates; a plurality of screw bolt holes are formed in the end plates and are used for connecting floor slabs. The full assembly type steel pipe concrete side frame combined shear wall structure has the advantages that the joint connection is fast and reliable; the construction is convenient; the construction quality is good; the bearing force is high; the quake-proof performance is good; the construction period is short; components can realize standardized production.

Description

【Technical field】 [0001] The invention belongs to the technical field of prefabricated assembled concrete structures in civil engineering, and in particular relates to a novel fully assembled steel pipe concrete frame combined shear wall structure. 【Background technique】 [0002] The traditional cast-in-place construction method has a low degree of industrialization, poor construction conditions, time-consuming and laborious, common quality problems are difficult to eradicate, and safety accidents occur from time to time, which is not conducive to energy conservation and environmental protection. In prefabricated concrete structures, joint connection technology is the key technology of this type of structure and the key to ensuring structural integrity and seismic performance. The horizontal joints of traditional prefabricated shear wall structures are mostly connected by sleeve grouting or grout-anchor lap joints. The connection is difficult, the construction operation and...

Problems solved by technology

Due to the lack of research and relevant engineering practice experience, the structural system is not perfect. The code mainly stipulates the assembled integral frame structure, assembled integral frame-cast-in-place shear wall structure, assembled integral shear wall structure, etc., which are demonstrated in my country. Most of the engineering and research are still prefabricated integral shear wall structures, and the research and application of prefabricated composite shear wall structures with steel pipe concrete frame is less. This type of fully assembled composite structure system and its connection are even more lack
