Shock-absorbing device of shockproof joint

Abstract

The invention provides a shock-absorbing device of a shockproof joint, and the shock-absorbing device comprises a left shock-absorbing unit and a right shock-absorbing unit which are symmetrically arranged on concrete structures at two sides of the shockproof joint, wherein the left shock-absorbing unit and the right shock-absorbing unit comprise steel barrels with inner sides which are embedded into the concrete structures; each steel barrel is internally provided with a piston with a piston rod, and a spherical steel cover plate is arranged at the outer end of each piston rod; a spring is arranged between each spherical steel cover plate and each concrete structure; the outer edge of each steel barrel is level with each concrete structure and is fixedly arranged through arranging an annular steel barrel cover plate; a spring is arranged between each spherical steel cover plate and each annular steel barrel cover plate; and the outer end of each piston rod is at least provided with two layers of spherical steel cover plates. According to the invention, the collision effect on buildings under an earthquake action is reduced, the buildings are prevented from being damaged, the construction is simple and the construction cost is low.

Description

technical field [0001] The invention relates to a shock-absorbing device for a shock-proof seam. Background technique [0002] Seismic joints widely exist in industrial and civil buildings; such as super-long structures, expansion joints are often required; structures with obvious height differences and irregularities need to be equipped with seismic joints, or building structures with settlement difference requirements need to be provided with settlement joints; building seismic codes It is stipulated that when expansion joints and settlement joints are set, their width should meet the requirements of seismic joints. [0003] Usually, after the seismic joints are set up, the building construction only adopts simple covering treatment measures, and no further protection requirements are imposed on the buildings on both sides of the seismic joints. As a result, under the action of an earthquake, the buildings on both sides are easily collided and damaged, and it is difficult ...

Problems solved by technology

[0003] Usually, after the seismic joints are set up, the building construction only adopts simple covering treatment measures, and no further protection requirements are imposed on the buildings on both sides of the seismic joints. As a result, under the action of an earthquake, the buildings on both sides are easily collided and damaged, and it is difficult to repair after the earthquake. Affects the beauty of the building and affects the safety of the structure
