Abstract

The invention discloses a hollow shear wall structure for a cross diagonal reinforcing bar. The hollow shear wall structure for the cross diagonal reinforcing bar comprises a shear wall body, wherein the inside of the shear wall body is provided with the horizontal-direction reinforcing bars of a wall body, the vertical-direction reinforcing bars of the wall body and wall body tie bars, wherein two groups of cross diagonal reinforcing bar cages are respectively arranged along the plane diagonal direction of the shear wall body; the cross diagonal reinforcing bar cages are bond and connected with the horizontal-direction reinforcing bars of the wall body and the vertical-direction reinforcing bars of the wall body; each group of cross diagonal reinforcing bar cage at least comprises four cross diagonal reinforcing bars and cross diagonal stirrups processed into a closed rectangle; the cross diagonal reinforcing bars and the cross diagonal stirrups are bond to form a rectangular strip-shaped cross diagonal reinforcing bar cage; and the inside of each space surrounded by the horizontal-direction reinforcing bars of a wall body, the vertical-direction reinforcing bars of the wall body, the wall body tie bars and the cross diagonal reinforcing bar cages is respectively embedded with a light internal die of a blocky foam plastic. The construction method for the hollow shear wall structure for the cross diagonal reinforcing bar comprises the following steps of: erecting a shear wall template; binding wall body reinforcing bar meshes; laying and binding the cross diagonal reinforcing bar cages; embedding the light internal die of the blocky foam plastic; and pouring and curing the shear wall concrete. According to the invention, materials are saved, the structural self weight is lightened, and the resistance to shock is good.

Description

technical field

[0001] The invention relates to a hollow shear wall structure with intersecting oblique reinforcement and a construction method thereof. Background technique

[0002] Shear wall is an important component in the concrete structure of high-rise buildings. It is widely used in high-rise building shear wall structures, frame-shear wall structures, plate-column-shear wall structures and various cylinder structures. The stress state and mechanical properties of important components bearing vertical and horizontal loads in building concrete structures directly determine the bearing capacity and structural safety of high-rise buildings. According to the current shear wall design and construction specifications, the wall material of the shear wall is solid reinforced concrete, and the interior is only equipped with horizontal and vertical reinforcement that meet the requirements of a certain spacing and reinforcement ratio, and there is no crossing diagonal reinforcem...
