Description
Technical field
The present invention relates to construction seismic resistance field, more particularly to a kind of anti-buckling underrelaxation friction-type antidetonation resistance of brace type
Buddhist nun's device.
Background technology
Frcition damper is that a class is dissipated a kind of control device of vibrational energy, its structure using the friction energy-dissipating of rubbing surface
Make simple, easy for installation, power consumption property good, and performance not temperature influence, be a kind of energy-consumption shock-absorption device commonly used in engineering.Absolutely
Most damper is all by the frictional damping layer between damping piece and outer folder, then by drawknot damping piece and outer clip
Part produces the friction damping force of antidetonation.But current existing friction damper has following four：
1st, average compressive stress is larger or Stress non-homogeneity for frictional damping layer, and frictional damping layer can produce larger friction to damage
Consumption；
2nd, the simple loading system using the big rigidity such as high-strength bolt, with loss of the friction material in friction process,
The friction damping force that pressure between frictional damping layer and damping piece is produced can produce larger decline；
3rd, due to damper is used to supporting axially (with frictional force parallel direction) be connected when by stable problem (mainly face
Outer unstability) and face in additional bending moment produce damper inside face in rotational problems constraint, more multi-form friction damper
Cannot be used for supporting axial connection, in the arrangement of damper using being above subject to certain restrictions.
4th, due to damper pretension force loading system more use high-strength steel (such as high-strength bolt), component stress compared with
Height is also corresponding higher to corrosion-resistant requirement.Traditional coating protection poor durability, maintenance cost is high, preferably to above-mentioned loading system
Carry out closed protective.
