Wall type viscous damper

Abstract

The invention belongs to the technical field of building shock absorption equipment, and relates to a wall type viscous damper. The wall type viscous damper comprises a box body, wherein liquid storage is respectively arranged at two ends of the box body along the width direction, the liquid storage is connected with an inner cavity of the box body, damping viscous liquid is arranged in the box body, a partition plate arranged in the box body divides the box body into two chambers which are connected with each other; two sheared steel plates arranged in parallel are fixedly disposed on the bottom surface of a upper connecting plate, the two sheared steel plates extend into the box body and are spaced by the partition plate, the opposite plate surfaces of the two sheared steel plates are respectively provided with limiting blocks, and the limiting blocks are in abutting contact with the corresponding partition plate. The damper has the advantages of high strength, stable and reliable work; and the arranged liquid storage is capable of reducing bubbles generated when the sheared steel plate moves, thereby making the output of the damper more stable.

Description

Technical field [0001] The invention belongs to the technical field of building damping equipment and relates to a wall-type viscous damper. Background technique [0002] Wall-type viscous dampers have been studied internationally, especially in Japan, and have been widely used. my country has developed relatively late. There are already some wall-type viscous dampers on the market, but most of them still have problems: 1. Currently existing wall-type dampers Most of the viscous dampers are open-type, and most open-type dampers have a small output. If a large tonnage damper is required, the size is often too large and the energy efficiency is relatively poor. 2. Existing wall-type viscous dampers. When the direction of earthquake or wind load is inconsistent with the direction of the inner steel plate, the inner steel plate is prone to transverse bending and deformation. In the light of the case, the energy dissipation capacity of the damping wall is reduced, and the damping wall ...

AI Technical Summary

Problems solved by technology

[0002] The wall-type viscous damper has been studied in depth in the world, especially in Japan, and it is widely used. In my country, it is developed late. There are some wall-type viscous dampers in the market, but most of them still have problems: 1. The existing wall-type Viscous dampers are mostly open-type, and most of the open-type dampers have a small output. If a damper with a large tonnage is required, the size is often too large and the energy efficiency is relatively poor

2. With the existing wall-type viscous damper, when the direction of the earthquake or wind load is inconsistent with the direction of the inner steel plate, the inner steel plate is prone to transverse bending deformation, which may lead to a decrease in the energy dissipation capacity of the damping wall, or lead to complete destruction of the damping wall , lose energy consumption

3. During the loading process of the open-type wall-type viscous damper, the viscous material is squeezed and often produces air bubbles, which makes the output of the damper unstable and affects the magnitude of the damping force
