STEEL-REINFORCED-CONCRETE JOIST STRUCTURE OF RAILROAD BRIDGE

摘要

Steel-reinforced-concrete joist structure of railway bridge consists of metal beams and reinforced-concrete plates with openings filled with hermetic material to which flexible connection stops are installed, those with one side are rigidly fixed to the upper plane of the upper horizontal sheet of metal beam. At one end of the flexible connection stops installed to openings in reinforced-concrete plate threading is provided, at the upper plane of the plate the stops are fixed by means of washers and nut, axis of placement of the flexible cylindrical stops for plate fixation coincides with axis of vertical metal sheet of cross section of metal beam, and joints between reinforced-concrete plates are grouted.
