GROUND PC TANK
To provide a ground PC tank capable of suppressing the occurrence of harmful cracks on concrete between PC steel materials even when an interval between the PC steel materials fixed at the same height is set smaller than a prescribed value.SOLUTION: The ground PC tank has: a base slab 2; a side wall 3 that is provided on the base slab 2; and a plurality of PC steel rods (PC steel materials) 8 that vertically extend over the base slab 2 and the side wall 3 and that are arrayed along the side wall 3 to introduce pre-stress therein. Spiral reinforcements (reinforcing members) 9 through which the plurality of PC steel rods 8 are inserted and which are buried in the concrete of the side wall 3 so as to be able to reinforce the concrete of the side wall 3 between the PC steel rods 8, 8 are provided, and the plurality of PC steel rods 8 are fixed to the side wall 3 at the same height.SELECTED DRAWING: Figure 2
【課題】同一高さにおいて定着されるＰＣ鋼材の間隔を規定値よりも小さくしても、ＰＣ鋼材間のコンクリートに有害なひび割れが生じることを抑制できる地上ＰＣタンクを提供する。【解決手段】基礎版２と、基礎版２の上に設けられた側壁３と、上下方向に延びて基礎版２と側壁３とにわたるとともに側壁３に沿って配列されてプレストレスが導入された複数のＰＣ鋼棒（ＰＣ鋼材）８と、を有する地上ＰＣタンクにおいて、複数のＰＣ鋼棒８それぞれが挿通し、側壁３のコンクリートに埋設されＰＣ鋼棒８，８間における側壁３のコンクリートを補強可能なスパイラル筋（補強部材）９を有し、複数のＰＣ鋼棒８は、それぞれ同一高さにおいて側壁３に定着されている。【選択図】図２
