Abstract: A fire-retardant fluid-coupling assembly includes a female-female, fluid-conveying pipe-coupling joint (24) without a flange thereon, a particular mounting system (22) for mounting the fluid-conveying pipe-coupling joint to the bottom wall (26) of a concrete form and an intumescent material wrap (25) wrapped about the fluid-conveying pipe-coupling joint at the form-wall-mounting end thereof. In a method of constructing a fire-retardant fluid-coupling with the assembly, the pipe-coupling joint (24) is mounted by the mounting system (22) to a bottom wall (26) of a concrete form with the intumescent material wrapped about the joint immediately adjacent the form wall and in contact therewith. Concrete (30) is then poured and allowed to harden.

Abstract: A support apparatus and method for attaching fluid-conveying pipe couplings of various lengths to be embedded in concrete barriers (30, 80, 172) of various thicknesses to a metal concrete form (26) involve a dual diameter outer disk (34) attached to an elongated compressing column (32) which extends through a hole (54) in the concrete form to a fastening means (38) in order to compress the fluid conveying pipe couplings (24) in fixed positions between the form and the outer disk. The fastening means can be attached to the compressing column at virtually any longitudinal positions. An inner disk (36) can also be put between the form wall and an inner end of the pipe coupling to provide extra rigidity. The disks act as forms to produce openings in the concrete barriers at opposite ends of the pipe couplings (24). Nothing extends beyond an outer, perimeter, surface of a forming portion of the outer disk.
