Title: PREFABRICATED CAVITY-TYPE PERPEND FORMING CONCRETE SHEAR WALL
Abstract:
A prefabricated cavity-type perpend forming concrete shear wall, comprising a reinforced concrete shear wall cavity segment (1) and an ordinary reinforced concrete shear wall segment (5). A reserved cavity (2) is provided inside the reinforced concrete shear wall cavity segment (1); cavity walls (3) are provided at two sides of the thickness direction of the reserved cavity (2); cavity end posts (4) are provided at two sides of the length direction of the reserved cavity (2); the ordinary reinforced concrete shear wall segment (5) and the reinforced concrete shear wall cavity segment (1), or the reinforced concrete shear wall cavity segments (1) are separated by reserving a vertical straight joint (6) or reserving a vertical concealed joint (7). By presetting a cavity in a shear wall, the weight and rigidity of a structure can be reduced, and perpends can greatly improve the ductility of the shear wall, and thus, the whole anti-seismic performance of the structure is improved.
