Footbridge and road bridge construction method using pier girder with upward reinforcement rib

摘要

The present invention can reduce the effect of wind load by using a girder for a pier having an upward reinforcement rib, and can facilitate the installation of a deck panel applied to a footbridge by using a deck panel fix fixture, thereby shortening the construction period, and increasing the reinforcement rib By supporting the formwork, pouring concrete for the floor slab can be carried out, so the construction period of the bridge can be shortened. A method of constructing a footbridge and a driveway bridge is provided. A method of constructing a footbridge using a girder for a pier having upward reinforcing ribs according to an appropriate embodiment of the present invention is a girder deck, a girder holding block protruding upward with a certain width at both ends of the girder deck, and mutually in the girder deck. A plurality of upward reinforcing ribs formed to protrude upward in parallel with a certain interval, rib valleys recessed to one side by the upward reinforcing ribs, and a plurality of horizontally buried in the upward reinforcing ribs in the longitudinal direction in the girder mounting block a girder body made of precast concrete with joint shear reinforcing bars protruding by a predetermined amount; For the installation of the deck panel to be used in the footbridge, it is disposed on the upper surface of each of the upward reinforcing ribs and is fixed to the girder body through a plurality of anchors installed on the lower surface of the deck panel fix fixture; manufacturing a girder for a pier consisting of; mounting the girder for the pier to the coping part installed on the top of the pile; Putting the deck panel on the upper surface of the girder for the pier, and fixing the deck panel to the deck panel fix holder through a fix; characterized in that it is constructed including.
