Abstract

The invention relates to the technical field of construction engineering, in particular to a superimposed shear wall with shear-resistant key grooves and a construction and manufacture method thereof. The superimposed shear wall comprises an inner layer precast concrete slab, an outer layer precast concrete slab and a middle cast-in-place concrete layer. The inner layer precast concrete slab and the outer layer precast concrete slab are connected through a steel bar truss. The shear-resistant key grooves are formed in the bottom of the inner layer precast concrete slab and the bottom of the outer layer precast concrete slab. Horizontal steel ribs and vertical steel ribs are arranged in the inner layer precast concrete slab and the outer layer precast concrete slab. Hooks used for hoisting are arranged on the top end face of the inner layer precast concrete slab and the top end face of the outer layer precast concrete slab. Embedded parts used for installation are arranged on the inner layer precast concrete slab. The superimposed shear wall is of an assembled integrated concrete structure and has the advantages of being good in anti-seismic performance, convenient to construct and install, capable of shortening the construction period and the like.
