ABSTRACT:
A method and apparatus for constructing an above ground concrete encased storage tank. The apparatus has a support assembly that extends from the baseplate of a concrete form, that supports, elevates, and secures an inner storage tank from the form baseplate, so that the tank may be completely surrounded by concrete. The form has removable walls that may be pivotally attached to the baseplate and initially in a horizontal position. The support assembly has anchor bolts that extend through holes in the baseplate. The anchor bolts are screwed into anchor nuts that are attached to a pair of brackets. The anchor nuts and brackets are spaced from the baseplate by sleeves that fit over the threaded portions of the anchor bolts. The brackets are constructed to support the storage tank, which is placed in the form on top of the support assembly. The tank is then fastened to the support assembly. After the tank is secured, the walls of the form are placed into a vertical position to create an enclosure with an opening at the top. Concrete is then poured into the form until the tank is completely surrounded by concrete. The concrete is allowed to set and the anchor bolts, sleeves and form are removed from the concrete. The holes created therein are patched with concrete, wherein there is constructed an above ground storage vault.
