ABSTRACT:
An internally threaded mechanical-joint bell fitting for cast iron pipe is adapted to be screwed onto an externally threaded end of a plain pipe section. The fitting has an integral bolting flange circumscribing the mouth of the bell and preferably includes a circumferential water stop flange at the smaller threaded end of the fitting. The fitting also includes mounting pads at the threaded end for attaching a free-standing support structure. The support structure consists of a pair of angle columns bolted at their upper ends to the mounting pads of the bell fitting and bolted at their lower ends to brackets that are adapted in turn to be bolted to studs preset in poured concrete footings for a tank or building wall. The bracket feet are bifurcated so that each bracket can bridge a water stop barrier set into the top surface of the wall fitting. Peripherally spaced recesses, aligned with bolt holes in the bolting flange of the bell fitting, provide clearance for heavy hex nuts threaded onto clamping bolts; so that two bell fittings can be used face-to-face to resist axial tensile forces acting on the joint, thereby eliminating the need for external thrust supports.
