Problems solved by technology
[0006] The present invention provides a prefabricated concrete shear wall body connected by bolt steel plates to solve the problem that the existing concrete shear wall connection method is not suitable for the prefabrication of shear walls with small aspect ratios and cannot withstand large axial compression ratios. Concrete shear walls have complex structural forms, low degree of prefabrication, and it is difficult to meet the requirements of improving seismic performance

The invention relates to the technical field of shear wall assembly and discloses a prefabricated concrete shear wall body connected through bolts and steel plates. The wall body comprises mutually-spliced prefabricated shear walls, channel steel connected with the prefabricated shear walls and the bolts matched with the channel steel. Flanges are arranged on the positions, at least close to the mutually-spliced side edges, of the outer sides of the prefabricated shear walls, the adjacent flanges of the two adjacent prefabricated shear walls are sleeved with the channel steel, and the bolts penetrate through the two opposite side faces of the channel steel and the adjacent flanges, in the channel steel, of the two adjacent prefabricated shear walls, so that the adjacent prefabricated shear walls are fixedly connected. According to the prefabricated concrete shear wall body connected through the bolts and the steel plates, the bolt and steel plate connection mode is utilized to enable the adjacent shear walls to be fixedly connected, and the wall body is simple in structure, convenient to assemble and capable of effectively reinforcing structural ductility, deformability and seismic performance.
Description
technical field [0001] The invention relates to the technical field of shear wall assembly, in particular to a prefabricated concrete shear wall connected by bolted steel plates. Background technique [0002] The joint connection method between prefabricated concrete shear walls has a direct impact on its mechanical performance. If the joint connection at the joint is very strong, it is easy to cause the cracking of the shear wall at the joint. Therefore, many scholars have carried out research on the connection problem of the joint position of the shear wall, and proposed a solution to add bolts to the joint, and members such as mild steel or U-shaped steel sheets to play the role of dampers. [0003] However, most of the precast concrete shear walls studied at home and abroad have an aspect ratio above 2.0, and the axial compression ratio is also relatively small, which is between 0.1 and 0.3. In fact, in many cases, the height of the precast concrete shear wall is simil...
