Assembly type cylinder friction energy dissipation shock absorber

Abstract

The invention relates to the technical field of building shock reducing and isolating, in particular to an assembly type cylinder friction energy dissipation shock absorber. The shock absorber comprises an outer cylinder body, and a friction component sliding along the inner straight line of the outer cylinder body. The friction component comprises a friction steel pipe fixedly connected to a right connecting plate. The outer cylinder body comprises a plurality of semi-circular friction compressing pieces fixed to the friction steel pipe by bolts, a constraining casing pipe arranged outside the semi-circular friction compressing pieces in a sleeving mode, and a left connecting plate fixedly connected with the constraining casing pipe. The friction steel pipe linearly slides along the semi-circular friction compressing pieces. Friction layers used for improving friction force are arranged on the inner sides of the semi-circular friction compressing pieces. The invention provides the assembly type cylinder friction energy dissipation shock absorber with reliable performance to solve the problems that the middle friction steel plate of an existing rubber-type friction energy dissipator deflects and is unstable and leads to excessive pressure on the steel plates on both sides and therefore warping is liable to occur, and friction force can not be adjusted.

Description

technical field [0001] The patent of the present invention relates to the technical field of building shock absorption and isolation, in particular to an assembled cylindrical frictional energy dissipation shock absorber. Background technique [0002] Usually in high-intensity earthquake-prone areas, after the building height reaches or exceeds the specified structure, designers often use cabinet frames, shear walls, cabinet shears and other structural forms to design. In this way, the size of beams and columns must be increased to meet the structural strength and Rigidity requirements will inevitably increase the amount of reinforced concrete and increase the cost. With the continuous improvement of the social and economic level and the continuous development of the technical level, people realize that the shock absorption and isolation technology of buildings can also meet the requirements of "not damaged by small earthquakes, repairable by moderate earthquakes, and not co...
