Abstract
A liquid storage tank made of panels each of which is made typically of glass reinforced plastic material and is generally rectangular and has integral flanges on all four sides. Each corner is relieved. The wall of the panel has at least one stiffening formation integral therewith and typically of dished circular configuration. Auxiliary members are used to complete the tank and occupy positions at the corners of the panels.
Claims10
A liquid storage tank having a floor and walls each made up of rectangular moulded panels of reinforced synthetic plastic material, each said panel comprising a wall the periphery of the panel at the corner of the wall being relieved, the wall having at the periphery thereof a flange integral therewith extending away therefrom and the wall having at least one stiffening formation integral therewith, said panels in each said wall and in said floor being secured together by first securement means engaging adjacent flanges of said panels, said tank further comprising auxiliary members each occupying a space defined by adjacent corners of said panels, each said auxiliary member having formation means restricting relative displacement of respective flanges of adjacent panels transversely of said adjacent panels, at least certain of said auxiliary members each having integral lug means positioned within said tank, said tank further comprising bracing means positioned wholly within said tank secured within said tank by second securement means to said lug means of said certain auxiliary members, and said tank further comprising seal element means held compressed by said first securement means in sealing relationship with said adjacent panels between adjacent flanges thereof and held compressed between said auxiliary members and respective surrounding panels in sealing relationship therewith by said first securement means.
A liquid storage tank having a floor and walls each made up of square moulded panels of glass reinforced synthetic plastic material, each said panel comprising a wall the periphery of the panel at the corner of the wall being relieved, the wall having at the periphery thereof a flange integral therewith extending away therefrom and the wall having a planar part adjacent said flange but having an integral central circular stiffening formation which is curved, said panels in each said wall and in said floor being secured together by first securement means engaging adjacent flanges of said panels, said tank further comprising auxiliary members each occupying a space defined by adjacent corners of said panels, each said auxiliary member having spaced formations between which the respective flanges of adjacent panels are located, at least certain of said auxiliary members each having integral lug means positioned within said tank, said tank further comprising bracing means positioned wholly within said tank secured within said tank by second securement means to said lug means of said certain auxiliary members, and said tank further comprising seal element means held compressed by said first securement means in sealing relationship with said adjacent panels between adjacent flanges thereof and held compressed between said auxiliary members and respective surrounding panels in sealing relationship therewith by said first securement means.
