INVERTED T CONCRETE GIRDER, RAHMEN BRIDGE USING INVERTED T CONCRETE GIRDERS AND CONSTRUCTING METHOD FOR RAHMEN BRIDGE

摘要

PURPOSE: An inverted T-girder, a rahmen bridge using the girder and a constructing method for the rahmen bridge are provided to prevent interference between protruding horizontal reinforcing bars and the deformation of the protruding horizontal reinforcing bars. CONSTITUTION: An inverted T-girder(1) having an inverted T-shaped cross section comprises a bottom flange(10) and a web(11). A coupling reinforcing bar(14) is installed in the edge between the web and the bottom flange, with both ends buried in the bottom flange and the web. The coupling reinforcing bar is positioned within the width of the bottom flange in the direction perpendicular to the bridge.
