Prefabricated shear wall, energy-consuming ductile prefabricated shear wall structure system and construction method
The invention discloses a prefabricated shear wall, an energy-consuming ductile prefabricated shear wall structure system and a construction method. The prefabricated shear wall comprises a wall body, a steel reinforcement framework in the wall body is not exposed out of the wall body, assembly holes are formed in the upper side and the lower side of the wall body respectively, and key grooves are formed in the left side and the right side of the wall body respectively. The prefabricated shear wall structure system comprises a plurality of prefabricated shear walls, a plurality of stress ribs, connecting parts formed in vertical seams between the prefabricated shear walls, edge components and horizontal cast-in-place belts. By means of the energy dissipation vertical seams and the horizontal cast-in-place belts, the shear wall has double anti-seismic functions, namely, the structure has large rigidity and bearing capacity under common required use loads (including common earthquakes and wind loads); and under the action of a strong earthquake, due to the cracking of the energy dissipation vertical seams and the horizontal cast-in-place belts, the structural rigidity is reduced, the damage form of the shear wall is changed, the structure has good ductility and energy dissipation capacity, the structure is prevented from collapsing, and therefore the anti-seismic property of the prefabricated concrete shear wall structure is improved.
本发明公开了预制剪力墙、耗能的延性预制剪力墙结构体系及施工方法，其预制剪力墙包括墙体，墙体内的钢筋骨架不外漏于墙体，墙体的上、下边分别设有装配孔，墙体的左、右边分别设有键槽。预制剪力墙结构体系包括若干预制剪力墙、若干受力筋、预制剪力墙之间竖缝中形成的连接部、边缘构件和水平现浇带。本发明通过耗能竖缝和水平现浇带，使剪力墙具有双重功能抗震，即结构在一般要求的使用荷载〔包括常遇地震、风荷载)下，具有较大的刚度和承载力；而在强震作用下，由于耗能竖缝和水平现浇带的开裂使结构刚度降低，改变剪力墙的破坏形态，使结构具有较好的延性和耗能能力，防止结构倒塌，从而提高了预制混凝土剪力墙结构的抗震性能。
