BOLT-TYPE SLIP PREVENTING METHOD USED FOR COMPOSITE STRUCTURIZATION OF EXISTING STEEL RAILWAY BRIDGE AND CONCRETE FLOOR SLAB

摘要

PROBLEM TO BE SOLVED: To provide a bolt-type slip preventing method used for composite structurization of an existing steel railway bridge and a concrete floor slab obtaining a strong floor slab joint part without weakening the strength of an existing steel bridge.;SOLUTION: The bolt-type slip preventing method used for composite structurization of the existing steel railway bridge and the concrete floor slab comprises removing existing sleepers to arrange new sleepers 3 at predetermined spaces on the upper faces of steel girders 1, laying rails 6 on the new sleepers 3, inserting bolt groups 2 at predetermined spaces between the new sleepers 3, arranging axial iron bars 4 penetrating the new sleepers 3, and axial reinforcements 5 welded to the axial iron bars 4, and placing floor slab concrete between the new sleepers 3 to construct the concrete floor slab 8.;COPYRIGHT: (C)2011,JPO&INPIT
