ABSTRACT:
A prestressed concrete tank having a core wall comprising elongated panels of precast concrete having on their outer face a sheet of sheet metal presenting parallel, longitudinal, undercut channels, is shown. The precast panels are assembled and spaced, in side-by-side relationship. Two, laterally extending metal flanges which run parallel with the elongated sides of the panels are provided. The flanges on adjacent panels overlap one another and are fastened by means of sheet metal screws. The joint formed is sealed with an elastomeric material. The advantages of the tank configuration are that expensive cover plates as have heretofore been used are avoided and the joinery is reduced by approximately one half thereby reducing the cost of sealant material and the labor required to apply it, as well as substantially reducing the likelihood of leakage from the tank.
