.. A cross beam sheeting structure of a prestressed concrete beam bridge

摘要

The present invention relates to a cross beam formwork installation structure of a PSC beam bridge, and more particularly, to reduce the cost and construction period in manufacturing the cross beam, because the width and height adjustment is simple and the assembly and disassembly is simple. A cross beam formwork installation structure of a PSC beam bridge can be shortened.;The formwork of the present invention is formed in a structure in which the PSC beam holder is installed and supported perpendicular to both PSC beams, while the PSC beam holder is formed in a square steel structure, and the cross beam external brace is fixed to the PSC beam holder. It is coupled with a bolt, the support base is coupled to the cross beam outer brace in the width direction in the width direction, the cross beam outer brace is coupled to a plurality of horizontal adjusters on the inner side of the cross beam, the cross beam A cross beam inner pedestal is positioned on the upper side of the support stand of the outer brace, and the cross beam tightening adjuster is coupled to the horizontal adjuster of the cross beam outer brace so that the fixing anchor supports the composite member square pipe in close contact with the composite member panel. While firmly supporting the concrete to be poured into the inside of the composite member panel, the one side The composite member square pipe is installed on the side, and the composite member square pipe and the composite member panel are made of fiber reinforced plastic (FRP) material, and the vertical reinforcing bars and horizontal reinforcing bars are placed inside, and concrete is poured to produce cross beams. It provides a cross beam formwork installation structure of the PSC beam bridge.
