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. Once the form has been removed, the intumescent material is exposed to atmosphere at the bottom of a concrete floor constructed by the form so that a fire in the story below immediately heats the wrap of intumescent material, causing it to expand and close off the fluid-conveying pipe-coupling.
