Energy dissipation and damping connecting structure and assembly method for fabricated concrete coupling beams

Abstract

The invention relates to the field of fabricated concrete structures, in particular to an energy dissipation and damping connecting structure and assembly method for fabricated concrete coupling beams. A split assembling system of a coupling beam structure in a shear wall with coupling beams in a concrete frame shear structure is composed of prefabricated coupling beams, prefabricated walls or prefabricated walls with beams. Pre-embedded connecting steel plates are mounted on the prefabricated coupling beams, the prefabricated walls or the prefabricated walls with the beams. When the coupling beams of the shear wall in the fabricated concrete frame shear structure are long, the connecting positions between the two ends of the coupling beams and the shear wall are split, and the prefabricated coupling beams and the prefabricated walls (two pieces) which are connected with the beam ends of the prefabricated coupling beams are fabricated correspondingly; when the coupling beams of the shear wall in the fabricated concrete frame shear structure are short, the middle span positions of the coupling beams are split, the two pieces of prefabricated walls with the beams are formed after being split, and the connecting method is the same. According to the energy dissipation and damping connecting structure and assembly method for the fabricated concrete coupling beams, components are connected through energy dissipation and damping connecting rings, the effects of energy dissipation and damping can be effectively achieved, the anti-shocking performance of the energy dissipation and damping connecting structure is greatly increased, and construction is simpler.
