BRIDGE CONSTRUCTION USING LATERIAL GIRDER

摘要

PURPOSE: A bridge construction method using a width girder is provided to remove the use of a shear key which is disadvantageous to the conventional installation and execution by coupling a part of a main girder with the bridge construction directly. CONSTITUTION: A bridge construction method using a width girder comprises followings. The width girder is mounted on a bridge post or an abutment. A mind girder(200) is lifted and placed at one side of the width girder. The both side of a cover plate having a plurality of bolt connecting grooves(410) is place at the side of the main girder and the width girder. Bolts are coupled in some bolt connecting grooves so that the connecting angle of the width girder and the width girder is changed within the preset range. The lifting force applied in the main girder is canceled. The rest of bolt is jointed in the bolt connecting grooves.
