THE PRE-CAMBER OF THE BRIDGE AND THE CURRENT METHOD FOR COMBINING EXTRUSION AND EXTRUSION NOSE WITH NOSE GIRDER INSTALLATION PROCESS

摘要

The present invention relates to an extruded nose for coupling a lower chord of a bridge in a free-camber and a method for installing a girder using the extruded nose, more specifically, to an extruded nose for coupling a lower chord of a bridge in a free-camber and a method for installing a girder using the extruded nose capable of responding to the sagging of the extruded nose generated by extruding the extruded nose connected with the girder by installing a leading camber on the front end part of the extruded nose. The extrude nose for coupling a lower chord of a bridge in a free-camber of the present invention comprises: an extruded nose upper chord which is straightly installed and coupled with a girder upper chord on one side thereof; an extruded nose lower chord which is straightly installed to be horizontal to the extruded nose upper chord, is coupled to the girder lower chord on one side thereof, and is bent in the direction of the extruded nose upper chord on the other side thereof; and a web member which is installed between the extruded nose upper chord and the extruded nose lower chord to connect the extruded nose upper chord with the extruded nose lower chord.
