ELASTICITY JOINT DEVICE OF BRIDGE

摘要

PURPOSE: An elasticity joint device of a bridge is provided to smooth the movement of equipment with elasticity, to improve durability of equipment and to minimize an impact caused by passing a vehicle through a joint. CONSTITUTION: The elasticity joint device of a bridge comprises: a module box(6) installed perpendicularly on a rail(2); a support beam(3) installed in the module box(6) and fixed with the rail(2) to support the load of the rail(2); a sliding bearing(4) and a sliding plate(7) for smoothing the operation of the support beam(3); a compression spring(5) associated with the sliding bearing(4) to absorb shock transferred to the support beam(3); and a control spring(8) installed to the side of the support beam(3) to guide the balanced movement of the rail(2).
