| 摘要 |
The present invention relates to a prefabricated water tank, enabling an outer diameter of a hemispherical reinforcement unit of a unit panel to be expanded to a curved unit of a flange (a bent unit between a plane unit and a flange unit) in order to distribute tensile stress of the unit panel generated by hydraulic pressure to the flange unit and the plane unit in order to improve strength of the water tank. Furthermore, the present invention provides a specific configuration where the water tank is efficiently assembled and installed by the improved unit panels. The prefabricated water tank as suggested by the present invention, can reduce a thickness of the unit panel based on the water tank having the same size since strength of the unit panel forming the prefabricated water tank is increased. |
