Description
Technical field
The invention belongs to technical field of building construction, limit energy-consuming device more particularly, to a kind of bridge rubber pad.
Background technique
With the development of economy, the construction business in China has also obtained unprecedented development, especially in terms of traffic,
China is vast in territory, and the construction of highway bridge is even more the most important thing.
Currently, Bridges in Our Country Aseismic Design is mainly to emphasize the intensity of pier body, pier body how to be made not fall in earthquake
It collapses.Mainly on pier body beam falling prevention stopping block is fixedly installed in used anti-fall beam construction, by the length travel amount of beam body and
Lateral displacement amount controls in a certain range.But contacted due to lacking between beam body and pier body, beam body and beam body, when strong
Higher earthquake is spent come when attacking, the impact acutely shaken by beam body, beam falling prevention stopping block easily occurs failure by shear and fails, and generation is fallen
Beam destroys.In " 5. 12 " Wenchuan earthquake, earthquake region majority bridge all receives destruction, and such as " all sorts of flowers bridge " this pier
Body is substantially intact, causes the example of bridge collapse too numerous to enumerate due to falling beam, it has also become the principal element that earthquake Bridge destroys,
Cause the common concern of bridge circle.With the rapid development of China's transport development cause, bridge is as the hinge in traffic lines
Engineering, no matter quantitatively or on development length all in rapid growth.And China is an earthquake-prone countries, bridge is once
Beam destruction is fallen in earthquake will make entire transportation network paralyse.
Currently, most widely used is exactly rubber pad, but still there are many insufficient for rubber pad in most mature anti-seismic technology
Place.The energy that rubber pad can only transmit longitudinal wave consumes, and avoids bridge floor and bridge pier that hard breakdown occurs, but shear wave passes
When coming, the coefficient of friction of rubber pad is smaller, will increase the relative displacement of bridge floor and bridge pier, and the probability that bridge floor falls off is very big.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of bridge rubber pads to limit energy-consuming device, should
Device is due to being provided with rubber pad, and when earthquake arrives, shear wave energy is transmitted to bridge pier, and energy is passed to rubber pad, rubber by bridge pier
Pulvilliform becomes consumption energy, and shear wave energy transmits bridge pier, bridge floor, and bridge pier and bridge floor generate relative displacement, the connection steel in rubber pad
Pipe generates mutual pulling force, and connected ball and annulus steel disc generate extruding, and energy dissipation spring generates deformation and consumes energy, avoids bridge floor and bridge
Pier generates hard breakdown, prevents bridge floor from generating obscission.
The technical solution adopted by the present invention is as follows：
Bridge rubber pad limits energy-consuming device, is arranged between bridge floor and bridge pier, symmetrically sets on the direction of bridge lateral
Two rubber pads are set, the rubber pad is arranged between bridge floor and bridge pier, and bridge floor is close in rubber pad top surface, and rubber pad bottom surface abuts
Bridge pier, horizontal pipeline communicate through rubber pad along the center of rubber pad side wall, are respectively arranged at rubber pad two side walls center
One protective cap, protective cap are the hollow cylinder with cavity, and cavity is connected to the horizontal pipeline in rubber pad, each protection
Cap respectively connects a joint steel pipe, and one end of two joint steel pipes is placed in horizontal pipeline, one of joint steel pipe it is another
One end is connected with bridge floor, and the other end of another joint steel pipe is connected with bridge pier, and two joint steel pipes are placed in horizontal pipeline
A connected ball is respectively placed at nozzle, two connected balls respectively connect an energy dissipation spring and are connected by energy dissipation spring.
Further, the protective cap is aluminum alloy material.
Further, the horizontal pipeline wall wall thickness 0.5-0.8cm, material are hard ester plastics.
Further, the L shape thickness of steel pipe 1-1.2cm in the joint steel pipe.
Further, the joint steel pipe is made of attachment base and L shape steel pipe.
Further, L shape steel pipe vertical direction the length 12-15cm, cross-directional length 20-25cm.
Further, length 15-20cm under the energy dissipation spring off working state.
Further, the connected ball is hollow steel ball.
Further, the connection bulb diameter is 1.4-1.6cm.
Further, the attachment base on the joint steel pipe is connected with bridge floor or bridge pier respectively by connecting bolt,
