STORAGE TANK STRUCTURE AND STRUCTURE FOR PREVENTING STAIN ON STORAGE TANK WALL SURFACE

PROBLEM TO BE SOLVED: To achieve a storage tank structure which can drastically improve economic efficiency while drastically improving safety of work in building a storage tank body and work efficiency, and a structure for preventing stains on a storage tank wall surface.SOLUTION: A storage tank structure includes: a storage tank wall made of reinforced concrete; a metallic roofing material connected to an inner top end of the storage tank wall through a receiving tool; a structure for preventing stains on storage tank wall surfaces which is a structure body for preventing stains on storage tank wall surfaces raised on a top end of the storage tank wall and has a top end in a position higher than a height at which the metallic roofing material is connected to the receiving tool; and a drain pipe provided in a lower part of the structure body for preventing stains on storage tank wall surfaces in a manner to penetrate through the structure body for preventing stains on storage tank wall surfaces from the metallic roofing material to an outer wall side of the storage tank wall.SELECTED DRAWING: Figure 3 【課題】 貯槽体の構築における作業の安全性と作業効率を格段に向上させつつ、経済効率も格段に向上させることの可能な貯槽構造及び貯槽壁壁面汚損防止構造を実現すること。【解決手段】 鉄筋コンクリートからなる貯槽壁と、前記貯槽壁の内側天端に受け具介して接続される金属製屋根材と、前記貯槽壁の天端上に立設される貯槽壁壁面汚損防止構造体であって前記金属製屋根材が前記受け具に接続される高さよりも高い位置にその天端を持つ貯槽壁壁面汚損防止構造と、前記貯槽壁壁面汚損防止構造体を前記金属製屋根材から前記貯槽壁の外壁側に貫通するように該貯槽壁壁面汚損防止構造体の下方に設けられる排水パイプとを具備する。【選択図】図３
