The invention relates to a shock absorption structure of a bridge and a manufacturing method thereof. The structure comprises a fixed steel plate, a protective steel plate and a middle shock absorption body, wherein the fixed steel plate and the protective steel plate are mutually parallel, the middle shock absorption body is fixed between the fixed steel plate and the protective steel plate, anchoring holes which are convenient for anchoring to a bridge structure are formed in the fixed steel plate, and the middle shock absorption body is a honeycombed rubber body which is formed in a way that a group of hollow rubber posts of which the cross sections are orthohexagonal are bonded in parallel. The manufacturing method comprises the following steps: manufacturing the middle shock absorption body; manufacturing the fixed steel plate, and reserving the anchoring holes; manufacturing the protective steel plate, and reserving exhaust holes and exhaust grooves; fixedly installing the buffer structure. According to the shock absorption structure, the mass of the whole structure is greatly reduced by adopting hollow rubber buffers, the occupied space is less, and the shock absorption structure is convenient to use in various extra-large, large and small bridges and fully performs shock absorption and insulation effects.
Description
technical field [0001] The invention belongs to the field of bridge damping design, in particular to a structure for buffering collision between main girders, between main girders and abutments or between main girders and stop blocks and a manufacturing method thereof. Background technique [0002] In recent years, earthquakes have occurred frequently all over the world, and the direct and indirect economic losses caused by each earthquake damage to bridge structures are very huge. Therefore, people's requirements for the seismic performance of bridges are also getting higher and higher. Improving the anti-stretch performance of bridges by introducing shock-absorbing and isolating structures is becoming a research and application hotspot. [0003] An effective measure to improve the seismic performance of bridges is to install buffer structures at the positions where collisions may occur under earthquakes to absorb the kinetic energy generated by earthquakes, thereby slowing...
