CONSTRUCTION METHOD FOR REVERSELY DRIVEN COLUMN, AND ERECTION METHOD FOR REVERSELY DRIVEN COLUMN
PROBLEM TO BE SOLVED: To provide a construction method or an erection method for a reversely driven column that may be applied to a reversely driven column of any length and weight, at the same time enhancing workability and curtailing a construction period.SOLUTION: In a method for constructing a reversely driven column 10, a plurality of crossed H-steels 10A, 10B, 10C, 10D, and 10E carried into a site where reverse driving is performed are connected by welding. A part of the reversely driven column 10 of a predetermined length shorter than a whole length is constructed by welding the plurality of crossed H-steels 10A, 10B, and 10C laid on a ground. A hole 2 is formed by excavating a ground at the site. The part of the reversely driven column 10 of the predetermined length is lifted using a crane 22 and inserted into the hole 2, and the crossed H-steel 10D is connected by welding on top of the reversely driven column 10Z.SELECTED DRAWING: Figure 6
【課題】逆打ち支柱の長さ及び重量にかかわらず採用できると共に、施工性を向上でき、工期を短縮できる逆打ち支柱の構築方法又は建て込み方法を提供する。【解決手段】逆打ち工法を実施する現場に搬入された複数のクロスＨ型鋼１０Ａ、１０Ｂ、１０Ｃ、１０Ｄ、１０Ｅを溶接により接合することによって逆打ち支柱１０を構築する方法である。当該構築方法では、まず、逆打ち支柱１０の全長未満の所定長さの部分を、複数のクロスＨ型鋼１０Ａ、１０Ｂ、１０Ｃを横に倒した状態で溶接により接合することによって構築する。また、現場の地盤を削孔することにより孔２を形成する。そして、逆打ち支柱１０の上記所定長さの部分をクレーン２２で建て起こして孔２の中に挿入し、該逆打ち支柱１０Ｚの上にクロスＨ型鋼１０Ｄを溶接により接合する。【選択図】図６
