Description

Ear fork type viscous damper

Technical Field

The utility model relates to the technical field of structural engineering, in particular to an earfork type viscous damper.

Background

The viscous damper is a speed-dependent energy consumption damper, and the basic principle is that the viscous damper is generated by means of the flow of internal viscous medium, so that part of seismic energy is consumed, and the safety of a main structure is protected. The viscous damper only provides additional damping to the structure, does not add static stiffness, and does not change the natural vibration period of the structure. The viscous damper product and the application are mature, and the viscous damper is a main stream product for building shock absorption.

Urban updating refers to the activity of modifying historical urban areas, old communities, old industrial areas, villages in cities and other areas in an urban built-up area in a comprehensive treatment, function adjustment, dismantling reconstruction and other modes, and is an important component which cannot be ignored in building engineering construction. The existing building tends to have low earthquake fortification level, and the existing building can not meet the current earthquake fortification level after long-term service. When the earthquake-resistant reinforcement is carried out by adopting the earthquake-resistant technology, the earthquake-resistant support and the connecting piece thereof, the energy absorber and the connecting piece thereof can be manufactured in advance, the site installation is convenient, the construction period is shortened, and the change of the original building appearance is reduced. Therefore, the seismic isolation technology can be preferentially selected for seismic reinforcement for certain historical buildings or public buildings.

In the damping and reinforcing implementation process, when the outer wall of a building cannot be damaged and only one side of the site is provided with a construction working surface, the traditional viscous damper is difficult to install, so that the use of the viscous damper is limited; in the newly-built project, when the double-wall arrangement form is adopted, and when the construction process is improper and the partition wall is constructed before the viscous damper, the traditional viscous damper cannot be normally installed, the built partition wall is required to be removed, and the partition wall is built by reworking after the viscous damper is installed in place, so that additional labor, materials and other costs are required to be spent.
