Assembled connection structure and method of shear wall coupling beam of prefabricated concrete frame-shear structure

Abstract

The invention relates to the field of assembly concrete structures, in particular to an assembly connection structure and method of coupling beams of shear walls of an assembly concrete frame shear structure. Grouting seams and equivalent bars are arranged between prefabricated coupling beams and prefabricated shear walls or between the coupling beams of the shear walls with half-span coupling beams for beam-wall or beam-beam connection. Holes are reserved in the prefabricated coupling beams and the coupling beams of the prefabricated shear walls or the shear walls with half-span coupling beams, spiral stirrups are arranged surrounding the holes in advance, the equivalent bars penetrate through the preserved holes, the reserved horizontal holes and the grouting seams between the beams and walls or between the beams are filled by grouting minimum inflation mortar, therefore the prefabricated coupling beams, the prefabricated shear walls and the equivalent bars, or the coupling beams of the shear walls with half-span coupling beams and the equivalent bars can be firmly integrated, and connection of the prefabricated coupling beams and the coupling beams of the prefabricated shear walls or the shear walls with half-span coupling beams can be achieved. The assembly connection structure and method greatly reduce the project construction cost and reduce site concreting wet construction.
