EARTHQUAKE-RESISTANT EXPANSION JOINT

摘要

An earthquake-resistant expansion joint capable of making its installation and dismantlement easier and dealing with three-axial behavior is provided. The earthquake-resistant expansion joint includes a hinge shaft support member mounted on one end of one deck slab of deck slabs con¬ stituting a bridge or an elevated road, a hinge finger plate member pivotally coupled to the hinge shaft support member and hinged to the hinge shaft support member at its one end to be slid in a lateral direction of the bridge or the elevated road along a pivot center shaft thereof, a finger plate member engaged with the other end of the hinge finger plate member at its one end to compensate a gap between the deck slabs depending on variation of the gap, and a finger plate support member fixed to the other deck slab in contact with the one deck slab to slidably support the finger plate member such that the finger plate member is slid in a lateral direction of the bridge or the elevated road.
