Abstract
A tank of relatively thin wall construction, and which is provided with a plurality of exterior reinforcing vertical and horizontal rib members, and in which the tank itself is of a generally rectangular shape in cross section, having a flat bottom, an upwardly arched roof, and inwardly arched side walls, the ribs extending completely around the tank at spaced intervals along its length, and being arranged in such a manner that the hydrostatic pressures developed in the tank will be resisted by bending stresses in the vertical ribs, and tensile stresses in the horizontal ribs, and in which provision is made for lengthwise expansion and contraction of the tank.
Claims12
A tank for flowable material such as fluids, liquid, semi-liquid materials and the like creating substantial hydro-static pressures therein, said tank comprising;
- a bottom wall, opposite side walls extending upwardly therefrom and a top wall and two end walls defining an elongated enclosed chamber;
- means supporting said bottom wall at spaced intervals and extending from side to side thereof;
- side support braces extending upwardly along the exterior of said side walls and having upper and lower ends;
- top support braces extending across the exterior of said top wall from side to side thereof;
- lower corners joining the lower ends of said side support braces with at least some of said bottom wall supporting means;
- upper corners joining the upper ends of said side support braces with respective ends of said top support braces;
- said side walls being characterized by a shape which is inwardly curved along the length of said tank, and said side support braces being shaped to follow the inwardly curved shape thereof, and wherein a straight line passing through a said side support brace and a straight line passing through its respective top support brace intersect one another at right angles at a point lying within the respective said upper corner joining said side brace and top brace, and wherein no such straight lines intersect said side walls or said top wall of said tank.
