SUPERSTRUCTURE OF BRIDGE, METHOD OF CONSTRUCTING SUPERSTRUCTURE OF BRIDGE, AND METHOD OF INCREASING WIDTH OF SUPERSTRUCTURE OF BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a superstructure of a bridge in which the arrangement of girder parts around receiving members is hard to be complicated. SOLUTION: This superstructure A of a bridge comprises the girder parts 11, extension floor boards 13, 20 extending from the girder parts 11 sideways, the receiving members 30 secured to the lower parts of the girder parts 11, respectively, and struts 40 diagonally rising from the receiving members 30. The extension floor boards 13, 20 are supported by the struts 40. An engagement projection is formed on the rear surface of the receiving member 30. An engagement recess is formed in the lower outer surface of the girder part 11 at a depth equal to or smaller than the covering depth of reinforcements. With the engagement projection engaged with the engagement recess, the receiving member 30 is secured to the girder part 11. COPYRIGHT: (C)2009,JPO&INPIT
