Abstract
The utility model relates to a rubber shock absorption stop dog which belongs to the technique of a fall resisting beam of the upper structure of a bridge during earthquakes. Because the top of one side of the utility model facing a beam body is in the shape of an outward concave nail or an inward concave bowl, the top of one side of the utility model backs on the beam body and is in the shape of a plane. When the horizontal vibrations of a frusta cap caused by earthquakes impact the beam body, the contact area between the rubber shock absorption stop dog and the beam body is reduced, the deformation capacity of the rubber shock absorption stop dog is increased, partial energy is absorbed and dissipated during a deformation process, the impact force between the beam body and the frusta cap is reduced, which is favorable for increasing the shock resistance of the whole bridge structure. The rubber shock absorption stop dog has the advantages of simple production, convenient installation, cheap cost and obvious effect, and is suitable for bridge projects to widely use and popularize.
Description
The rubber shock-absorbing block relates to the anti-seismic technology of bridge engineering structure, the anti-fall beam technology of bridge superstructure when further relating to earthquake.
Be used at present to limit because of earthquake causes the common practice of the relative lateral displacement between bridge superstructure and the pier cap and be: with the additional concrete limited block of the corresponding pier cap of beam body position cast.This concrete limited block produces hard hit when hitting being subjected to action of horizontal seismic to bridge top beam body, and this impact produces bigger power in bridge superstructure and substructure, make the bridge breaking-up easily.
The purpose of this utility model is that design a kind ofly avoids the steel concrete block hard hit on beam body and the pier cap to hit, and the certain deformation amount will be arranged with the dissipates vibration energy when bump, thus the shock resistance of raising bridge construction.
To achieve the above object, the utility model is to realize by such scheme: be stained with rubber shock-absorbing block of the present utility model on former steel concrete block, this rubber shock-absorbing block towards a side roof part of beam body be cambered outwards spike or concave bowl-shape, the bottom of beam body one side is plane dorsad, this structure decrease the contact area of rubber shock-absorbing block and beam body, increased deformability, seimic pier cap horizontal vibration becomes soft bump to beam body impact, and by block intussusception and dissipating, impact has significantly reduced.
The utility model has the advantages that:
(1) because the shape at the top of rubber shock-absorbing block has adopted nail type or bowl type, make the vibration bump become soft bump, and block absorbs when being impacted and consume energy effectively, improved the shock resistance of bed rearrangement bridge.
(2) the utility model is made simply, and is easy for installation, with low cost, very easily applies.
Accompanying drawing is embodiment of the present utility model; Wherein
Fig. 1. installation site of the present utility model schematic diagram
Fig. 2. structural representation of the present utility model
The utility model will be further described in conjunction with the accompanying drawings.
The rubber shock-absorbing block by towards the top (1) of beam body (3) one sides for cambered outwards spike or concave bowl-shape, a side bottom (2) of beam body (3) be plane block rubber composition dorsad.
Steel concrete block (5) on former pier cap is reserved and the corresponding hole (4) of shape size of the present utility model in the face of a side of beam body (3) earlier, then the utility model is embedded in steel concrete block (5) preformed hole (4) of pier cap (6), stick with glue agent and cement.Horizontal vibration that earthquake produced and horizontal movement become soft bump to the effect of impact of beam body (3) on rubber block, and because the elasticity and the viscid characteristic of rubber itself, thereby the intussusception and the impact that dissipated, the danger of beam has prevented to fall, bridge security when having guaranteed earthquake is worthy of popularization.
Claims (1)
1. rubber shock-absorbing block is characterized in that: towards the top (1) of beam body (3) one sides for cambered outwards spike or concave bowl-shape, the bottom (2) of beam body (3) one sides is the plane dorsad.
