CONSTRUCTING METHOD OF RAILING ONE BODY TYPE BRIDGE

摘要

PURPOSE: A handrail integrated bridge construction method is provided to minimize a weight of a bridge since a separate handrail is not needed, to install a format height of the bridge to be low, and to shorten a construction period by installing a trussed structure on a handrail after being assembled in advance. CONSTITUTION: A handrail integrated bridge construction method comprises steps of: installing a girder(120) including a first longitudinal beam(121) that is installed in a longitudinal direction of a bridge, a second longitudinal beam(123) that is located at an upper part of the first longitudinal beam, and a vertical support beam(125) that is bound between two ends of the first longitudinal beam and the second longitudinal beam that are positioned at top and bottom of the bridge; and installing a driving way(110) comprising a horizontal pedestal(112) and a slab(114). The horizontal pedestal is combined across between a pair of upper parts of the first longitudinal beam of a girder in a horizontal direction, and the slab is located at the upper part of the horizontal pedestal. A truss(130) is installed to be assembled between the first longitudinal beam and the second longitudinal beam of the girder.
