A structural member(11) for a water storage tank comprises a rectangular base(12) composed of a base plate(16), and a support leg(13) installed to the rear of the support. The base comprises a rectangular frame, and a rib(17) installed in the frame, wherein the base plate includes plural through holes(16a) to function as a flow passage of water and an exhaust port, and plural engaging projections(18) and engaging grooves(19a) to engage with each other when piling up structural members by coupling the surface of a base with the surface of another base, and the rib includes a notch(17a) to function as a flow passage of water and an exhaust port and to promote the inflow of water to the inside of each support leg and to fill up a storage space with water smoothly. The support leg comprises four corner legs(20) installed to four corners of the base, four middle legs(21) installed to the middle of four sides of the base, and four central legs installed to the center of the base, wherein a rugged engaging portion(23) composed of plural front walls having different heights and a wall connecting the front walls in the shape of a step is formed on the front of the corner leg, and engaging portions are formed on the front of the middle leg and the front of the central leg in the same shape of the engaging portion of the corner leg to engage with each other to pile up plural structural members.</p> |
