Abstract

The invention discloses a shearing-resisting reinforcement structure for a junction domain where the connecting beam and the wall beam of a concrete shear wall are connected. The junction domain wherethe connecting beam and the wall beam of the concrete shear wall are connected is reinforced by a rectangular steel plate, wherein the rectangular steel plate the concrete shear wall are anchored through the opposite penetration of high-strength bolts; the side surface of the connecting beam is laterally evenly divided into a plurality of same square unit modules; the top of each square unit module is provided with L-shaped angle iron and a rectangular steel belt; a square steel plate is inlaid in the center of each square unit module through a drilling way, and each square steel plate and the connecting beam are in opposite penetration connection through a high-strength bolt; and each square steel plate is connected with the vertex of each square unit module in a welding way through an inclined shearing-resisting steel plate, wherein the connection way can improve the integral shearing-resisting bearing capacity of the connecting beam and perform a certain protection function for a sub-structure formed by the shear wall and the connecting beam. The shearing reinforcement structure has the characteristics of being reasonable in stress, clear in force transfer, simple in construction and high in shearing-resisting bearing force and anti-seismic properties.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a concrete shear wall connecting beam and a wall-beam connecting node domain shear reinforcement structure. Background technique [0002] Concrete shear wall, as a kind of form of lateral force-resisting components in high-rise buildings, plays a role in resisting horizontal loads. The shear wall structure is widely used at home and abroad, and it is also a kind of structural form with frequent accidents in engineering. According to the needs of building functions, door and window openings are often set up in the shear wall structure to meet functions such as traffic, ventilation, and lighting, and the maintenance between walls is connected by connecting beams. Previous earthquake damages have shown that the failure of shear wall structures mostly occurs in coupling beams and the joint domains where coupling beams and shear walls are connected, and cou...
