Self-resetting fabricated shear wall structure connecting device

Abstract

The invention provides a self-resetting fabricated shear wall structure connecting device. The connecting device comprises a prefabricated shear wall and a foundation shear wall, and the prefabricatedshear wall is internally provided with a steel reinforcement cage and a plurality of longitudinal bars. The connecting device is characterized in that the prefabricated shear wall comprises an end confined region, a middle confined region and a distributing reinforcement region, wherein the middle confined region is located in the middle of a wall body of the prefabricated shear wall, the end confined region is located at both ends of the wall body of the prefabricated shear wall, and the distributing reinforcement region is located between the end confined region and the middle confined region; the purpose is to apply energy-dissipation earthquake-reduction to the fabricated structure, according to the connecting mode, the energy dissipation capacity of the shear wall structure is improved, the shear wall has self-resetting capacity under lateral loads, the seismic demand of the whole structure can be reduced, and the seismic performance of the main structure is improved; and at thesame time, the connecting device has the characteristic of easy industrial production and is more efficient and quicker, and the problems of inconvenience and pollution of energy consumption caused byon-site wet working are avoided.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a self-resetting assembled shear wall structure connecting device. Background technique [0002] The prefabricated shear wall structure refers to the standardized production of various components of the structure, including prefabricated shear walls, prefabricated beams, prefabricated floors, etc., in the factory, and then the prefabricated components are connected by bolts, welds or post-cast concrete at the construction site. connected structure. The prefabricated shear wall structure has light weight, low rigidity and good ductility. The prefabricated components are industrially produced, and the manufacturing process can be more refined than ordinary cast-in-place components. It has the advantages of labor saving, fast construction progress, and is conducive to realizing building energy saving and facilitating industrial production. And mechanized construction ...
