PROBLEM TO BE SOLVED: To provide an erection apparatus for constructing a first block, a method of constructing a movable work vehicle using part of the erection apparatus, and an overhanging constructive method of a bridge.;SOLUTION: The erection apparatus 1 for constructing the overhanging first block is formed of: supports set on a capital; support beams 5 extending from the capital 12 in an overhanging direction; and detachable transverse support beams 26 supported by the support beams 5, used as a transverse beams 25 of the movable work vehicle 34, and extending in a bridge axis orthogonal direction. The erection apparatus thus formed functions to hang and support timbering by the transverse support beams 26. After construction of the overhanging first block by the construction and erection apparatus, the transverse support beams 26 for hanging and supporting the timbering are built in as the transverse beams of the movable work vehicle movably set on the overhanging first block, and the movable work vehicle having the transverse beams built therein functions to construct an overhanging second block and subsequent ones.;COPYRIGHT: (C)2009,JPO&INPIT
