Self-resetting energy dissipation device and mounting method

Abstract

The invention discloses a self-resetting energy dissipation device. The self-resetting energy dissipation device comprises an upper box type steel plate component, a middle box type steel plate component, a lower box type steel plate component, end box type steel plate components, disc spring elastic resetting assemblies, pull rods and steel plate energy dissipation components; the end box type steel plate components are arranged at two ends above the lower box type steel plate component respectively, the top of each end box type steel plate component is open, multiple partition boards are arranged on the inner wall of each end box type steel plate component, and grooves penetrating through the partition boards are formed in the middles of the partition boards; each steel plate energy dissipation component is located between the middle box type steel plate component and the corresponding end box type steel plate component; each disc spring elastic resetting assembly comprises disc springs, rigid base plates and nuts, the rigid base plates are arranged at two ends of the disc springs, outer sides of the rigid base plates are fastened by the nuts, and the rigid base plates at the twoends of the disc springs are connected between the two adjacent partition boards in a propped manner. The energy dissipation device is convenient to construct, simple in structure and high in stability and has energy-dissipation and self-setting functions.

Description

technical field [0001] The invention relates to the technical field of effective shock absorption, and more specifically relates to a self-resetting energy dissipator and an installation method. Background technique [0002] Energy dissipation and shock absorption technology refers to the installation of energy dissipation devices at designated parts of the structure, through which the installed energy dissipation devices produce friction, bending, shearing and other elastic-plastic hysteretic deformations to dissipate energy or absorb the energy input into the structure by earthquakes or other vibrations , thereby reducing the vibration response of the main structure, avoiding damage to the structure itself, and protecting the safety of the structure itself. The traditional energy dissipation and shock absorption technology is to install energy dissipators in the structure to consume energy, but the residual deformation of the structure after the earthquake is too large, an...

AI Technical Summary

Problems solved by technology

The traditional energy dissipation and shock absorption technology is to install energy dissipators in the structure to consume energy, but the residual deformation of the structure after the earthquake is too large, and it is often impossible to return to the original position

However, the existing self-resetting device is generally equipped with prestressed tendons, memory alloy and other materials to provide restoring force, but it has the disadvantages of difficult construction, large loss of pre-pressure, and high cost.
