A prefabricated damping staircase with built-in two-way damping particles

Abstract

The invention discloses an assembled vibration-damping stair with built-in bidirectional damping particles. The assembled vibration-damping stair with the built-in bidirectional damping particles canmeet the requirement of building functions in a normal working state, provides the resistant-lateral rigidity for a major structure under the action of wind vibration and an earthquake, at the same time, has enough dissipation capacity, can effectively reduce the damage of the stair and the major structure, and is easy to replace after vibration or damage. The invention belongs to the technical field of a vibration-damping control and assembled structure of a structural project. The assembled vibration-damping stair with the built-in bidirectional damping particles comprises energy dissipationsteps, rectangular holes, upper-layer cavity bodies, lower-layer cavity bodies, rectangular grooves, the damping particles, springs, rebound plates, load-carrying ribs, distribution ribs, vertical plates, embedded steel bars, floorboards, rest platform plates and reserved holes. The assembled type vibration-damping stair can be prefabricated and processed and rapidly assembled on the scene, the bidirectional vibration damping of a frame structure body is realized, and the vibration damping efficiency is improved.

Description

technical field [0001] The invention relates to a prefabricated vibration-damping staircase with built-in two-way damping particles. The fabricated vibration-damping staircase can be prefabricated and quickly assembled on site. Under the action of vibration and earthquake, it provides lateral stiffness for the main structure and has sufficient energy dissipation and vibration reduction performance, which can effectively reduce the damage of itself and the main body of the structure, and is easy to replace after the earthquake or damage. It belongs to the vibration reduction control of structural engineering. And the field of assembled structure technology. Background technique [0002] With the development of society and the frequent occurrence of earthquakes in recent years, people pay more and more attention to the anti-seismic performance of buildings, but the anti-seismic design of buildings in most parts of our country is not perfect. Previous earthquake disasters have...
