ERECTION METHOD OF T-GIRDER

摘要

PROBLEM TO BE SOLVED: To provide an erection method of a T-girder that eliminates a concern over falling of an embedded mold during concrete casting, falling of the embedded mold with time due to corrosion or other reasons, and peeling off of gap closing concrete, the erection method also mitigating work burden and reducing construction costs.SOLUTION: An erection method of a T-girder is for installing a plurality of T-girders 1 by spanning the T-girder between each span of a substructure A of a bridge including a bridge pier and a bridge abutment, the T-girder having a T-shaped vertical cross-section orthogonal to an axial direction. The erection method includes a mold frame installation step in which a resin embedded mold 5 is installed in a gap closing part 4 between the adjacent T-girders 1 in a bridge width direction (Y-direction) from a top surface of the T-girder 1 without using a scaffold, the resin embedded mold having a rectangular bottom plate 50, a pair of side plates 51 rising from both edge parts in a shorter-side direction of the bottom plate 50 and inclined to widen a distance therebetween, and a connecting rib 52 connecting the pair of side plates 51 to each other.SELECTED DRAWING: Figure 10
