PURPOSE: A prefabricated water tank is provided to obtain rigidity of a water tank and to efficiently implement the rigidity according to water pressure distribution. CONSTITUTION: A first external reinforcing member (110) comprises a first reinforcement unit (111) and a second reinforcement unit (113). A second external reinforcing member (120) reinforces rigidity of the lower part of the first external reinforcing member. A support frame comprises a first support unit (131) and a second support unit (133). A reinforcing frame (150) is fixed to a connection part formed on the lower part of the first external reinforcing member. A part of the first reinforcement unit is installed between flange units of side wall panels (21) in order to be closely fixed, and the rest part is exposed to the outside. The second reinforcement unit is connected to the rest part of the first reinforcement unit and is at right angles with the first reinforcement unit. The first support unit is connected to an edge of a bottom surface and is connected to the flange units of side wall lower panels. The second support unit supports the lower part of the first external reinforcing member and the lower part of the second external reinforcing member. |
