STEEL TOWER ASSEMBLY METHOD USING STEEL TOWER ASSEMBLY JIG, AND LIFTING MAST FOR STEEL TOWER ASSEMBLY JIG
PROBLEM TO BE SOLVED: To overcome a safety problem with a steel tower assembly method using a conventional steel tower assembly jig that a boom for the steel tower assembly jig needs to be installed at a high place.SOLUTION: A steel tower assembly method using a steel tower assembly jig of the present invention includes: a first step for fixing the steel tower assembly jig comprising a mast and a boom at an upper part of a steel tower portion assembled to a desired height; a second step for fixing a lifting mast that extends downward on the mast of the steel tower assembly jig, and assembling a steel tower portion of a desired height on the steel tower portion that has already been assembled; a third step for releasing the fixed state between the steel tower assembly jig and the steel tower portion, and lifting the lifting mast using a lifting device to lift the steel tower assembly jig to the desired height; a fourth step for fixing the steel tower assembly jig to the steel tower portion; and a fifth step for assembling the steel tower portion of the desired height using the steel tower assembly jig, on top of the steel tower portion that has already been assembled.SELECTED DRAWING: Figure 5
【課題】従来の鉄塔組立用治具を用いた鉄塔の組立方法は、上記鉄塔組立用治具のブームを高い位置に設置する必要があり、安全性に問題があった。【解決手段】本発明の鉄塔組立用治具を用いた鉄塔の組立方法は、所望の高さまで組み立てられた鉄塔部分の上部に、マストとブームとよりなる鉄塔組立用治具を固定する第一工程と、該鉄塔組立用治具のマストに、下方に延びるせり上げ用マストを固定すると共に、上記鉄塔組立用治具を用いて、上記組み立てられた鉄塔部分の上に、所望の高さの鉄塔部分を組み立てる第二工程と、上記鉄塔組立用治具と上記鉄塔部分との固定を解除すると共に、揚重装置により、上記せり上げ用マストを上昇させて、上記鉄塔組立用治具を所望の高さまで上昇させる第三工程と、上記鉄塔組立用治具を上記鉄塔部分に固定する第四工程と、上記鉄塔組立用治具を用いて、上記組み立てられた鉄塔部分の上に、更に、所望の高さの鉄塔部分を組み立てる第五工程とよりなることを特徴とする。【選択図】 図５
