A construction method of a rahmen structure to be introduced with a pre-moment and an anchorage device used for the same are provided to support a span sufficiently with a girder having the relatively small cross section by introducing a pre-moment, which enables to offset a bending moment occurring by load, to a rahmen structure in advance. A construction method of a rahmen structure comprises the steps of pin-joining a steel girder to a joint member projected from a column to mount a steel girder(S110), installing one or more cross beams between the steel girder and another steel girder spaced out from the steel girder to make the steel girders support each other horizontally(S120), introducing bending moment to the steel girder to make the steel girder bend to be convex downward(S140), joining at least one connection which is pin-joined while the bending moment is introduced to transfer a moment(S150), and removing the introduced bending moment(S160). |
