Seismic Isolation Temporary Bridge

Abstract

The invention discloses an earthquake-isolated temporary bridge, which comprises a bridge frame, a bridge deck and two connecting bases, the bridge deck is laid on the bridge frame, and the two connecting bases are respectively fixed on the two ends of the bridge frame, and carry the bridge frame Fixed to the external ground, the connection base includes an upper connection plate, a lower connection plate and a shock-isolation layer, the upper connection plate is fixed on the lower side of the bridge end, and the shock-isolation layer is fixed on the upper connection plate and the lower connection plate Between the connecting plates, anti-slip lines are provided on the lower side of the lower connecting plate. The earthquake-isolation temporary bridge of the present invention can realize the shock-isolation effect between the vibration on the bridge surface and the lower connecting plate through the setting of the shock-isolation layer, so that the position of the lower connecting plate caused by the vibration of the vehicle can be effectively avoided There is an offset problem.

Description

technical field [0001] The invention relates to a bridge, more specifically to a temporary seismic isolation bridge. Background technique [0002] In the process of field building construction, the road conditions faced by transport vehicles are generally not flat road conditions, some even have gaps, so in the actual construction process, it is generally chosen to erect a temporary bridge on the gap for transportation Vehicles pass. [0003] The existing temporary bridge structure includes a bridge frame and a bridge deck. The bridge deck is fixed on the bridge frame for vehicles to pass through. Preliminary fixation completes the construction of the temporary bridge, and when the transport vehicles drive across the bridge deck, some vibrations will be generated, and this vibration will be transmitted to both ends of the bridge frame, so that after a period of use, It is easy to have the problem of loosening of the fixed structure between the two ends of the bridge frame ...

[0003] The existing temporary bridge structure includes a bridge frame and a bridge deck. The bridge deck is fixed on the bridge frame for vehicles to pass through. Preliminary fixation completes the construction of the temporary bridge, and when the transport vehicles drive across the bridge deck, some vibrations will be generated, and this vibration will be transmitted to both ends of the bridge frame, so that after a period of use, It is easy to have the problem of loosening of the fixed structure between the two ends of the bridge frame and the ground, so that the position of the bridge frame may be shifted during use, which will lead to the problem that the bridge cannot span the gap well
