PROBLEM TO BE SOLVED: To provide a girder structure, a junction structure of the girder structure and a concrete slab, a concrete slab, a girder bridge and a bridge capable of joining a flange plate and the concrete slab with higher workability than ever before without reducing displacement prevention performance.;SOLUTION: A girder structure 10 comprises: a flange plate 12; a corrugated steel web plate 14 which is arranged in a longitudinal direction of the flange plate 12 and connected to a lower surface of the flange plate 12; and T-steel with external protrusions 16 arranged in the longitudinal direction of the flange plate 12 with a web section 16A thereof connected to an upper surface of the flange plate 12. A flange section 16B of the T-steel with the external protrusions 16 has protrusions 16C and at least a portion of the web section 16A of the T-steel with the external protrusions 16 is positioned directly on the corrugated steel web plate 14.;COPYRIGHT: (C)2013,JPO&INPIT
