摘要
An improved prestressed concrete tank having a core wall comprising elongated panels of precast concrete having on their outer faces a sheet of sheet metal presenting parallel, longitudinal, undercut channels is shown. The panels include lateral sheet metal flanges which extend parallel to the elongated sides of the panels and laterally outward therefrom. The flanges have a flange lip on the outermost edge of the flange. The lip extends outwardly from the tank in a direction substantially perpendicular to the panel. The panels are assembled in spaced, side-by side- relationsip such that the flange lips of adjacent panels are spaced from one another. A sheet metal splice member having a channel shape is interposed in the space between the flange lips of the adjacent panels. The splice member has upstanding sides which abut the lips of the adjacent flanges. The upstanding side and the flange lip adjacent to it are seamed together in a tight fold, thus locking the adjacent panels together. The advantages of this technique is that it creates a tighter, more waterproof seam between adjacent panels without penetrating the sheet metal diaphragm with sheet metal screws or other fasteners. Furthermore, such a joint eliminates the use of sealants in joining adjacent panels.
