CONSTRUCTION METHOD OF INNER TANK OF FLAT-BOTTOMED CYLINDRICAL TANK
PROBLEM TO BE SOLVED: To curtail a construction period of a flat-bottomed cylindrical tank.SOLUTION: A construction method according to an embodiment of the present invention includes the following steps for: installing a plurality of frames on a bottom plate; forming an annular plate below the frame; forming a first tier of a side plate on the annular plate, under the frame; forming a second tier and onwards of the side plate sequentially above the frame; and removing the frame and welding the first tier of the side plate and the second tier and onwards of the side plate. A step for sequentially forming the second tier and onwards of the side plate is performed simultaneously with either or both of the step for forming the annular plate and the step for forming the first tier of the side plate on the annular plate.SELECTED DRAWING: Figure 2
【課題】平底円筒型タンクの工期を短縮する。【解決手段】本発明の一態様に係る施工方法は、複数の架台を底板上に配置する工程と、架台の下でアニュラプレートを形成する工程と、架台の下でアニュラプレートの上に側板の１段目を形成する工程と、架台の上で側板の２段目以降を順に形成してゆく工程と、架台を撤去し、側板の１段目と側板の２段目以降を溶接する工程と、を含み、アニュラプレートを形成する工程及びアニュラプレートの上に側板の１段目を形成する工程のうちの一方又は両方に並行して、側板の２段目以降を順に形成してゆく工程を行う。【選択図】図２
