Description
Technical field
The invention belongs to technical field of civil engineering, it is related to a kind of energy-consuming shock absorber, provides and put especially by gear
The frcition damper of big displacement.
Background technology
Energy-dissipating and shock-absorbing technology is the damper in parallel in the lateral resistant member of structure, and most earthquake is consumed by damper
Energy, is a kind of active and effective antidetonation strategy so as to ensure the safety of agent structure.Displacement during existing damper work is led to
It is often equal with the relative displacement of tie point, therefore damper is preferably arranged on the larger position of structure relative deformation, such as structure is relative to be become
Shape is small, and damper can not effectively play its power consumption function because displacement is small.Therefore, scholars have developed new technology so that damper
Displacement be more than tie point relative displacement, such as：Band displacement equations dress is disclosed in Publication No. CN 104314192A patent
The damper put, i.e., increase the displacement of damper, but lever transmission is less efficient using lever principle, and only damper size is very
Larger displacement could be obtained when big, the inconvenience of installation is thus caused, also have impact on the use function of building.
