APPARATUS FOR TESTING CAPACITY EXPANSION AND WATERPROOF OF EXPANSION JOINT OF A BRIDGE

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for testing a stretching and waterproofing performance of a bridge expansion joint device, which comprises a plurality of guide rails arranged side by side; A fixed-side specimen mounting unit fixed to one side of the guide rails and detachably coupled to one side of the expansion joint apparatus specimen; A moving-side specimen-attaching unit slidably installed on the other side of the guide rails to detachably connect the other of the specimen to the expansion joint apparatus; A reciprocating drive unit for reciprocating the moving-side specimen-mounting unit; And a load cell for measuring a force acting on the reciprocating drive unit. According to the present invention, the expansion joint performance and the waterproof performance of a telescopic joint installed in a bridge are tested under the same conditions as actual conditions to accurately measure the performance of the expansion joint.
