RESILIENT BRIDGE SUPPORT HAVING A PIEZOELECTRIC DEVICE

摘要

The present invention relates to a resilient bridge support having a piezoelectric device, wherein a plurality of piezoelectric devices are mounted on a resilient support for a bridge, intended for absorbing shocks generated by loads on the bridge deck panels and by deformation, and installed between the deck panels and piers of the bridge to measure vehicle loads applied to the deck panels of the bridge and generate electric energy using the vibration energy generated by vehicles traveling over the bridge. For this purpose, a resilient support for a bridge of the present invention comprises: an upper plate (50) fixedly installed on the undersurface of the bridge deck panel; a base plate (10) fixedly installed on the top surface of the pier; an upper fixed panel (40) and a lower fixed panel (20) fastened and fixed by fastening bolts (22, 42) to the upper plate (50) and to the base plate (10), respectively; and a rubber pad (30), the top and bottom surfaces of which are thermally bonded and fixed to the upper and lower fixed panels (20, 40), respectively, and including a plurality of steel panels (31) in a multi-stack configuration filled therein, wherein the resilient support is configured with a plurality of piezoelectric devices (1) for converting vibrations transmitted from the bridge deck panels into electric energy, and the piezoelectric devices (1) are stacked between each of the steel panels (31) within the rubber pad (30).
