Composite material energy dissipation type shear wall

The utility model relates to a composite material energy dissipation type shear wall which comprises an upper steel plate, a lower steel plate, a middle steel plate, constraint steel plates, visco-elasticity materials, pencil leads and bolt holes. Holes are reserved in the middle steel plate and the constraint steel plates, the visco-elasticity materials are filled into the gaps between the middle steel plate and the constraint steel plates, and after the steel plates and the visco-elasticity materials are vulcanized, lead is poured into the reserved holes to be solidified so that the pencil leads can be formed. The bolt holes are formed in the upper steel plate and the lower steel plate, and the upper steel plate and the lower steel plate are connected with an upper framed girder and a lower framed girder through bolts to be used as the energy dissipation type shear wall. Under the action of vertical loads, wind loads and small seisms, only rigidity can be achieved by the device, and accordingly the vertical loads, small horizontal loads and bending moment can be resisted. Under the action of middle seisms and large seisms, seismic energy can be consumed by the visco-elasticity materials and the pencil leads together, the pencil leads and the visco-elasticity materials can be greatly deformed, so that damping is achieved while the device has rigidity, and thus various seismic responses of the structure are reduced. The numbers and sizes of visco-elasticity material layers and the pencil leads can be designed flexibly according to needs. According to the composite material energy dissipation type shear wall, the anti-seismic conceptual design is clear, the structure is simple, the cost of use materials is low, and construction and replacing are convenient.
