Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in fig. 1, an assembled composite energy dissipation shear wall includes two shear wall members, a plurality of seismic isolation supports are uniformly arranged between the two shear wall members, one end of each seismic isolation support is connected with one shear wall member, the other end of each seismic isolation support is connected with the other shear wall member, at least one shape memory alloy rod is arranged between every two adjacent seismic isolation supports, one end of each shape memory alloy rod is connected with one shear wall member through a rod connecting member, the other end of each shape memory alloy rod is connected with the other shear wall member through a rod connecting member, and the shape memory alloy rods between the two shear wall members are distributed in a corrugated shape.
As shown in fig. 1, in the present embodiment, three seismic isolation supports are uniformly arranged between two shear wall members, and two shape memory alloy rods are arranged between two adjacent seismic isolation supports. When two shear force wall components take place relative displacement about the time, can make shape memory alloy member reciprocal to be drawn or the pressurized, the shock insulation support also can take place horizontal reciprocating displacement simultaneously, through the horizontal shear deformation of shock insulation support, can dissipate the energy of earthquake input, play the effect of power consumption shock attenuation.
As shown in fig. 1 and 2, the vibration isolation support comprises a vibration isolation rubber pad and end connecting plates connected to two ends of the vibration isolation rubber pad, the end connecting plate at one end of the vibration isolation support is connected with one shear wall component through a bolt, and the end connecting plate at the other end of the vibration isolation support is connected with the other shear wall component through a bolt. In the embodiment, a plurality of screws are embedded in each of the two shear wall members, and the screws in the two shear wall members respectively penetrate through the end connecting plates at the two ends of the seismic isolation support and are fixed with the end connecting plates at the two ends of the seismic isolation support through nuts.

The rod connecting piece is embedded in the shear wall member in advance, so that the shear wall member can keep the integral stability when the shape memory alloy rod is deformed, the capacity of the shape memory alloy rod for bearing horizontal shear force and limiting the horizontal displacement of the shear wall member through deformation is fully exerted, the seismic isolation support can still keep stable in the deformation process of horizontal shear, and the energy consumption capacity cannot be lost due to overlarge deformation.
As shown in fig. 3, a pin is provided at one end of the rod member connecting member embedded in the shear wall member. The arrangement of the pins can strengthen the connection between the rod piece connecting piece and the shear wall member, and the connection stability between the rod piece connecting piece and the shear wall member is improved.

The included angle between the shape memory alloy rod and the horizontal plane is 16 degrees.
The working principle of the invention is as follows:
the invention is applied to high-rise assembled buildings, and when an earthquake occurs, two shear wall members of a building structure can generate horizontal relative displacement. Because the two ends of the shape memory alloy rod piece are respectively connected with the two shear wall members through the rod piece connecting pieces, and the end connecting plates at the two ends of the shock insulation support are respectively connected with the two shear wall members through the bolts, when the two shear wall members generate relative horizontal displacement, the shock insulation support firstly generates small-amplitude horizontal displacement, meanwhile, the shape memory alloy rod piece can slow down the horizontal displacement of the shock insulation support and limit the maximum horizontal displacement of the shock insulation support, and the shape memory alloy rod piece can be pulled or pressed in a reciprocating manner while slowing down the reciprocating horizontal displacement of the shock insulation support.

The energy consumption capacity of the shape memory alloy rod piece can be enlarged by reasonably setting the diameter of the shape memory alloy rod piece, the size of a nut adopted by the connecting screw rod, the thickness of a friction gasket and the like; the larger the diameter of the shape memory alloy rod piece is, the larger the force resisting the lateral shearing is, and the capability of limiting the displacement of the shear wall component is also improved; by applying a certain pretightening force to the shape memory alloy rod piece, the shock absorption effect of the large damper can be generated, and the manufacturing cost is saved.
In summary, the seismic isolation support and the shape memory alloy rod piece are arranged between the two shear wall components, so that the vertical load of the structure can be effectively transmitted, the assembled shear wall system can have certain lateral resistance, and the laterally input energy can be effectively dissipated through the cooperative work of the seismic isolation support and the shape memory alloy rod piece; and on the premise of ensuring that the integral structure has certain bearing capacity, the overall ductility and energy consumption capability of the assembled shear wall structure are improved, and meanwhile, the self-resetting characteristic of the shape memory alloy rod piece is utilized to reset the shear wall member and the energy consumption device after energy consumption. The invention has simple structure, convenient assembly, short construction time consumption and convenient and simple daily maintenance, can not fail due to improper daily maintenance, can reduce the size of the required shear wall member, improves the space utilization rate of the building to a certain extent and creates better social benefits.
