Background
In high-intensity earthquake areas, beam falling is the most common and serious damage form of bridges, causes traffic interruption, has great influence on emergency rescue and disaster relief, has high post-disaster repair difficulty, and needs to be prevented by adopting proper measures. The anti-seismic stop block is a common anti-beam-falling measure, and the longitudinal and transverse anti-seismic stop blocks are generally arranged at the positions of bridge supporting points in the anti-seismic design of the bridge, so that the main beam is limited to generate large displacement under the action of an earthquake, and the longitudinal and transverse beam falling is prevented. Bridge pier stud is mostly circular, and conventional antidetonation dog is the rectangle with the pier contact surface, only is better to the limiting displacement of girder in perpendicular to dog medial surface direction, and when girder and pier stud took place great relative displacement, the antidetonation dog could play limiting displacement in all the other directions, and the girder was close to the emergence and is fallen the roof beam state this moment, and the reliability is lower. And the earthquake action direction has great contingency, sets up conventional antidetonation dog in a plurality of directions, and the structure is too complicated, and receives the space restriction and is difficult to implement. Therefore, an anti-seismic stop block with a simple structure is required to be found at present so as to adapt to the contingency of the earthquake action direction, well limit the displacement of the main beam in any direction and ensure that the fulcrum of the circular pier does not fall down to damage under the action of strong earthquake.

In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model provides an arc antidetonation dog structure suitable for circular pier, includes inboard arc steel sheet, outside rectangle steel sheet, the steel sheet of putting more energy into and rubber gasket, is located upper and lower, three outside rectangle steel sheets and connects as an organic whole constitution frame-type arc antidetonation dog, and this frame-type arc antidetonation dog's inside sets up the steel sheet of putting more energy into, and inboard arc steel sheet is connected with the outside rectangle steel sheet that is located upper and lower, the rubber gasket sets up in the surface of inboard arc steel sheet.
Furthermore, the inner arc-shaped steel plate, the outer rectangular steel plate and the stiffening steel plate are all connected by welding.
Furthermore, arc antidetonation dog is arranged around circular pier along bridge is indulged, the crossbeam to keep fixed interval, ensure to restrict the girder displacement in arbitrary direction homoenergetic betterly, prevent to take place to fall the roof beam and destroy.
Furthermore, the cross section line of the arc-shaped steel plate on the inner side of the arc-shaped anti-seismic stop block is an arc.
Furthermore, the arc-shaped anti-seismic stop block is connected with the concrete girder in an anchoring manner or welded with the steel girder.
