A high pressure resistant and water tight panel assembled tank consisting of unit panels, each unit panel is formed with a protrusion portion in the form of a pyramid or truncated pyramid progressively increasing its height toward a center of the square wall surface of the panel and has securing flanges at the peripheries of the panel. The unit panels consist of (a) bottom wall panels of which securing flanges are folded in a direction opposite to the extending direction of the protrusion portion and (b) side wall panels of which securing flanges are folded in a direction the same as that of the protrusion portion and having partially thicker portions, and the securing flanges of the wall panels embracing sealing seats therebetween are clamped together outside of the tank to form the assembled tank. Assembled tie rods and panels for mounting supply and drain pipings are incorporated in the tank to improve the pressure resistance of the tank and to facilitate assembling, settling, piping and cleaning of the tank.
A panel assembled tank comprising square wall surface unit panels connected together, each unit panel formed with a pyramidal protrusion portion progressively increasing in height toward the panel center and having integral folded securing flanges at the peripheral edges thereof, said protrusion portion including corner section portions radially arranged at the unit panel corners and forming therebetween edges of the pyramidal protrusion portion, said wall surface unit panels comprising bottom wall panels, at least some of said bottom panels having securing flanges folded in a direction opposite to the extending direction of said protrusion portion thereof, said panels further comprising side wall panels, each side wall panel having securing flanges folded in the same direction as the protrusion portion of the side wall panel, said side wall panels being formed peripherally along the bottoms of said flanges with flat portions, and means for securing the flanges of said bottom and side wall panels together and facing outwardly to form said tank.
