To provide an aboveground tank capable of easily generating compression stress by effectively introducing tension with circumferential tensile materials to a side wall and a bottom slab.SOLUTION: An LNG tank has a tank body including a bottom slab 5 and an oil protective barrier 2. The bottom slab 5 is constituted of an upper bottom slab 5a and a lower bottom slab 5b independently from each other, and the oil protective barrier 2 is firmly connected to the upper bottom slab 5a. Tensioning force in a tank peripheral direction is introduced to the oil protective barrier 2. In an external periphery of the lower bottom slab 5b, a step 53 the upper face of which is lowered in a step shape, and in the external periphery of the upper bottom slab 5a, a thick portion 52 a thickness of which increases downward to be thicker than that of a central portion 50. The thick portion 52 is disposed in the step 53.SELECTED DRAWING: Figure 2
【課題】周方向の緊張材による緊張力を側壁および底版に効果的に導入でき、圧縮応力を発生させることが容易な地上タンクを提供する。【解決手段】LNGタンクは底版５と防液堤２を含むタンク躯体を有し、底版５は、上層底版５ａ及び下層底版５ｂに分けて構成され、防液堤２は上層底版５ａに剛結される。防液堤２にはタンク周方向の緊張力が導入される。また下層底版５ｂの外周部に、上面の位置が段状に低下した段部５３が設けられ、上層底版５ａの外周部に、中央部５０よりも下方に増厚した増厚部５２が形成され、段部５３に増厚部５２が配置される。【選択図】図２
