Horizontal connection structure of site-construction L-shaped shear wall with steel concrete combined pipes prefabricated in factory

Abstract

The invention provides a horizontal connection structure of a site-construction L-shaped shear wall with steel concrete combined pipes prefabricated in a factory. The horizontal connection structure comprises a first steel concrete combined pipe with the linear horizontal section and a second steel concrete combined pipe with the linear horizontal section. Multiple pouring penetrating holes are uniformly formed in the rear end face of a first rectangular barrel-shaped steel pipe and the front side face of the left end of a second rectangular barrel-shaped steel pipe from top to bottom. At least two penetrating reinforced holes corresponding to each pouring penetrating hole in a front and rear mode are formed in the rear side of the second rectangular barrel-shaped steel pipe. Site horizontal anchor ribs penetrate through the inside of the penetrating reinforced holes. The front ends of the site horizontal anchor ribs penetrate forward through the pouring penetrating holes and stretch into the first rectangular barrel-shaped steel pipe. The ductility and compressive strength of concrete are greatly improved, the plasticity and toughness properties of the whole steel concrete overlapped shear wall structure are greatly improved, and the non-deformability and compressive strength of the shear wall are greatly improved; meanwhile, the rectangular barrel-shaped steel pipes are package in the concrete so that the problems of fireproofing and corrosion protection of steel structure buildings are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a horizontal connection structure of an L-shaped shear wall constructed on site of a factory prefabricated steel-concrete composite pipe. Background technique [0002] The components of the prefabricated building can be industrialized in the factory. The components are equivalent to standard products, and they can be installed directly on site. field, has its incomparable superiority; components are produced standardizedly in the factory, the quality is more guaranteed than on-site production, and can be effectively controlled. The high-standard mechanization of components reduces the number of on-site personnel. Both labor cost and safety production are helpful. [0003] The components of existing prefabricated buildings have the following technical problems: 1. Poor fire protection performance; 2. Poor corrosion resistance; 3. Poor durability of the ...
