A viscous shear damper with replaceable steel inserts

Abstract

The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and discloses a viscous shear damper with a replaceable steel plate, including an upper end plate, a lower end plate, several steel plates and several pins; The first middle vertical board is arranged on the side; the left vertical board, the right vertical board and the movable middle board are arranged on the lower end board, and the second middle board and the third middle board are arranged on the middle board at intervals. A front baffle and a rear baffle are set between the board and the right vertical plate, two middle baffles are set on the inner surface of the left vertical plate and the right vertical plate, and two middle baffles are set between the two middle baffles and the middle laminate. viscometer; several lead blocks are set on the first middle vertical plate; several shock absorbers are arranged between the first middle vertical plate and the front baffle and between the first middle vertical plate and the rear baffle, and each steel insert Run through each vertical board and connect with several bolts respectively. The deformation is borne by multiple energy-dissipating components, with excellent shock absorption and energy-dissipating performance, good hysteresis curve, and easy replacement.

Description

Technical field [0001] The invention belongs to the seismic and shock absorbing area of ​​civil engineering, involving a viscous shear damper with replaceable steel sheet. Background technique [0002] Metal damper, especially a soft steel damper, is a shock absorbing component of the elastoplastic deformation energy consumption when the metal is yield, since the metal has good hysteresis characteristics after entering the plasticity, and during the elastic deformation process A large amount of energy is absorbed, thus being used to create different types and consumption shock absorbers. From the stress form, it can be divided into axial yield type, shear flexaded, bending yield type and torsion kettle-free damper, existing energy consumption damper has the following types: torsion beam energy console, bending beam consumption A can, U-shaped steel plate energy console, steel rod console, ring energy consumption, double circular ring energy consumption, plus circular ring consump...

Problems solved by technology

[0005] The object of the present invention is to overcome the above-mentioned prior art, the existing conventional damper has poor energy dissipation effect in an earthquake, is easily damaged, the maintenance and replacement cost is relatively expensive, and the anti-seismic performance is reduced after maintenance.
