DIAGNOSTIC APPARATUS FOR HANG DOWN STEEL-BEAM IN UPPER CANTILEVER SECTION OF BRIDGE

摘要

An apparatus for diagnosing sagging of a steel beam in an upper cantilever section of a bridge is provided to secure safety of the bridge by informing a manager computer of deformation of a fixing bracket and a bridge bearing so as to promptly cope with the situation. An apparatus for diagnosing sagging of a steel beam in an upper cantilever section of a bridge includes an elastic support bar(10), a lift operation tube(20), and a diagnosing tube(30). The elastic support bar is installed at a fixing bracket and is lifted down when a cantilever is sagged. The lift operation tube is coupled with the elastic support bar and has an inner corrugated tube lifted down when the elastic support bar is lifted down. The diagnosing tube displays introduction of an antifreezing solution on a transparent window(31) when the corrugated tube is lifted down and informs a manager computer of the excessive introduction of the antifreezing solution.
