Abstract
The utility model discloses a shock-absorbing elastic-plastic damper for a bridge, which has the advantages of simple structure and better shock-absorbing effect. The shock-absorbing elastic-plastic damper for the bridge consists of an upper anchoring plate (10) and a lower anchoring plate (20), wherein the upper anchoring plate (10) is provided with an upright post (11) while the lower anchoring plate (20) is provided with an upright post (21); two groups of transverse bridge direction C-shaped crank arm beams (31) and two groups of longitudinal bridge direction C-shaped crank arm beams (32) are symmetrically arranged between the upper anchoring plate (10) and the lower anchoring plate (20); and the two ends of the transverse bridge direction C-shaped crank arm beams (31) and the longitudinal bridge direction C-shaped crank arm beams (32) are in pin connection with the upright post (11) of the upper anchoring plate (10) and the upright post (21) of the lower anchoring plate (20). The benefitss of the utility model are better mechanical property and shock-absorbing effect; and with simplified structure, the utility model helps reducing the bridge cost.
Description
Technical field
The utility model relates to bridge damping elastoplasticity damper.
Background technology
The elastoplasticity damper utilizes the theoretical development of energy-dissipating and shock-absorbing; It possesses good antidetonation shock attenuation function, has avoided the damage of bridge when earthquake; The elastoplasticity damping supporting seat combines ball shaped steel bearing and damper, the effect of usual performance ball shaped steel bearing, the effect of performance elastoplasticity damper can effectively consume seismic forces during earthquake, has improved the reliability and the durability of bridge greatly with minimum engineering input.The elastoplasticity damper is a kind of of passive energy dissipation device in the structure Passive Control, have stable hysteretic characteristic, good low-Cycle Fatigue Characteristics, be not subjected to the advantages such as influence of environment temperature, when earthquake or wind shake, energy by the distortion of steel generation plastic yielding hysteresis in the dissipation input structure, thereby reach the purpose of vibration damping, make it very wide in actual application in engineering prospect.There is baroque deficiency in existing elastoplasticity damper.
The utility model content
Technical problem to be solved in the utility model provides a kind of bridge damping elastoplasticity damper, designs simplification and make it to have good damping effect.
The technical scheme that its technical problem that solves the utility model adopts is: bridge damping elastoplasticity damper of the present utility model, comprise last anchor plate with column and following anchor plate with column, it is characterized in that: described go up anchor plate, down be symmetrically arranged with between the anchor plate two groups of direction across bridge C shapes crank arm beam and two groups along bridge to the C shape beam of cranking arm, direction across bridge C shape crank arm beam, along bridge to C shape crank arm beam two ends respectively with last anchor plate column and following anchor plate column pin joint.
The beneficial effects of the utility model are to have good mechanical performance and damping effect; Designs simplification helps reducing the bridge cost.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model bridge damping elastoplasticity damper.
Fig. 2 is the lateral view of the utility model bridge damping elastoplasticity damper.
Component names shown in the figure and pairing mark: go up anchor plate 10, column 11, down anchor plate 20, column 21, direction across bridge C shape crank arm beam 31, along bridge to the C shape beam 32 of cranking arm.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, bridge damping elastoplasticity damper of the present utility model comprises last anchor plate 10 with column 11 and the following anchor plate 20 with column 21.Described go up anchor plate 10, down be symmetrically arranged with between the anchor plate 20 two groups of direction across bridge C shapes crank arm beam 31 and two groups along bridge to the C shape beam 32 of cranking arm, direction across bridge C shape crank arm beam 31, along bridge to C shape crank arm beam 32 two ends respectively with last anchor plate 10 columns 11 and following anchor plate 20 columns 21 pin joints.Last anchor plate 10, following anchor plate 20 are fixedlyed connected with beam, pier respectively, and the elastoplasticity damping action of beam because each C shape is cranked arm is to the displacement movement generation retardation of bridge with respect to bridge pier.
