Problems solved by technology

[0002]In the existing laminated plate shear wall, when the upper and lower floors or the left and right wall panels are installed, the stressed steel bars are not connected to each other, and only between the wall panels Connecting steel bars are placed in the middle of the cast-in-place concrete layers between the two. The structural system formed by this connection method, the steel bars of the shear wall cannot participate in the structural stress, the shear resistance is poor, the structural strength is low, the construction is difficult, and the labor cost is high, so it is not suitable for high-rise buildings. Construction, not conducive to the industrial production and application of construction

Embodiment 1

[0016] A laminated slab shear wall with exposed buckled steel bars, which comprises: a precast concrete outer slab 1, a precast concrete inner slab 3, the precast concrete outer slab has a group of outer slab internal steel bars 4 , the prefabricated concrete inner slab has an inner steel bar 5, the precast concrete outer slab and the precast concrete inner slab are connected by a connecting lattice steel bar 2, and the inner steel bar of the outer slab Annular closed stirrups 6 are placed on the internal reinforcement of the inner layer plate, and stressed steel bars 7 are inserted into the four corners of the annular closed stirrups.

Embodiment 2

[0018] According to the laminated plate shear wall with exposed buckled steel bars described in Embodiment 1, the internal steel bars of the outer layer plate protrude to the inside of the shear wall to form a 90-degree bent shape, and the inner layer of the inner layer plate The steel bars protrude to the side of the shear wall and are made into a 90-degree bent shape.

Embodiment 3

[0020] A method for connecting laminated slab shear walls with exposed buckled steel bars described in Embodiment 1 or 2, the prefabricated concrete outer layer slab with the single-layer horizontal and vertical reinforcement mesh of the shear wall as the skeleton, the connecting lattice steel bar, and the The single-layer horizontal and vertical reinforcement mesh of the shear wall is a prefabricated concrete inner layer slab, the outer layer and the inner layer are connected by connecting lattice steel bars, and the size of the outer layer is on one side or two sides or three sides or four sides, etc., which are larger than the corresponding sides of the inner layer plate, the internal steel bars of the outer layer plate protrude to the inside of the shear wall, and are made into a 90-degree bend shape, and the internal steel bars of the inner layer plate extend toward the shear wall The side protrudes and is made into a 90-degree bent shape, and the outer and inner panels ar...

Abstract

The invention relates to a laminated slab type shear wall with exposed buckled steel bars and a connection method. Existing laminated slab shear walls are not connected to each other, and the steel bars of the shear wall cannot participate in the structural stress. The shear resistance is poor, the structural strength is low, the construction is difficult, and the labor cost is high. It is not suitable for high-rise buildings and is not conducive to construction. Industrial production and application. A laminated slab shear wall with exposed fastening steel bars, which consists of: a precast concrete outer slab (1), a precast concrete inner slab (3), and a set of inner steel bars on the precast concrete outer slab (4) The precast concrete inner slab has internal steel bars (5) on the inner slab, and the precast concrete outer slab and the precast concrete inner slab are connected by connecting lattice steel bars (2). Ring-shaped closed stirrups (6) are placed on the steel bars inside the plate, and stressed steel bars (7) are inserted into the four corners of the ring-shaped closed stirrups. The invention is applied to the laminated slab type shear wall with exposed fastening steel bars.

Description

Technical field: [0001] The invention relates to a laminated slab type shear wall with exposed buckled steel bars and a connection method. Background technique: [0002] In existing laminated slab shear walls, when the upper and lower floors or the left and right wall panels are installed, the stressed steel bars are not connected to each other, and only the connecting steel bars are placed in the middle of the cast-in-place concrete layer between the wall panels. In the formed structural system, the shear wall reinforcement cannot participate in the structural force, the shear resistance is poor, the structural strength is low, the construction is difficult, the labor cost is high, it is not suitable for high-rise buildings, and it is not conducive to the industrial production and application of buildings. Invention content: [0003] The object of the present invention is to provide a laminated slab shear wall with exposed buckled steel bars and a connection method. [0...
