Description
Technical field
This utility model is related to bridge construction technical field, and in particular to a kind of to connect upper bracket plate component and limited block
Connect, be fixed into an entirety effectively to reduce destruction of the earthquake to bridge.
Background technology
Friction pendulum system is a kind of dry friction sliding and shock isolation body that the Dr.VictorZayas in the U.S. in 1985 is proposed first
System, cardinal principle is to isolate bridge or grid structure thing itself with ground, using the design cycle of rubbing surface come extending structure
The vibration period of thing, seismic power augmentation effect is reduced, by the coefficient of friction for adjusting rubbing surface, effectively consume ground
Shake energy.
Traditional friction pendulum support is generally divided into fixed pattern, multi-orientation type and one-way type（Laterally or longitudinally）Three types,
When usually, fixed pattern and one-way type（Laterally or longitudinally）Bearing is limited by stopping means bi-directionally or uni-directionally（Laterally or longitudinally）
Mobile, under design seismic force effects, protection device is cut off, and releases spacing, and bearing plays shock insulation power consumption effect.

Stress is closed, stress is complex, product design check and performance analysis is all acquired a certain degree of difficulty, further, since adopting
With separate structure, monolithic stopping means just need to consider whole Bearing Seat Force that left and right isolating construction is added up in design ＆ check
Safety plug needs double setting, and on the one hand product cost is caused to increase, and is on the other hand also the waste to resource.
In addition, according to existing national standard, bridge pad is both needed to arrange reliable friction pair protection device, and traditional rubs
Pendulum support friction pair protection device is wiped, is remained using monoblock ethylene propylene diene rubber or thermoplastic transparent polyurethane rubber, utilized
Screw, hangs on product surface.The type friction pair protection device, only provides anti-when propping up a dwell of sley, acting on without dust storm, water wave
Dirt function, but can not fix due to hanging coaming plate lower open, in water wave, wind and rain, eolian action or product has displacement movement
During relative slip, slip secondary surface（Mirror face stainless steel plate surface or SF-1B wear ribs）Easily expose, dust, rainwater, water wave, bird
The thing such as class feces and the grains of sand is fallen within so as to cause to damage to friction pair on friction pair, even if without above-mentioned weather condition, because not being
Hermetically sealed, bird excrement and the grains of sand also fragile surface of friction pair affects product frictional behaviour, so affect product performance and
Durability.
