Abstract

PURPOSE:To facilitate connection between a drive story and a final main setting pillar so as to shorten a construction period and improve quality by fitting a girder supporting member to the outside face of a hollow sheath pipe elevating along a main setting pillar, and supporting a girder on the over position of the sheath pipe with this member. CONSTITUTION:A drive story 1 is elevated along a main setting pillar 2 at a pillar/ girder joint part. Building of each story is promoted. Hence a final main setting pillar 6 with a final girder bracket 7 fitted thereto is finally erected on the real fixing position of the girder 5. Next the girder 5 is elevated along the outer circumference of the main setting pillar 6 up to the upper end. At this time the girder 5 is supported on the over position of a sheath pipe 3, and the end part of the girder 5 and the end part of the bracket 7 are fixed so as to confront to each other, without contacting the girder 5 and a girder supporting member 4 with the final girder bracket 7. Hereby, connection of the drive story 1 with the final main setting pillar 6 can be easily performed, so as to largely contribute to labor saving, shortening of the construction period, and improvement of the quality.
