Abstract

A pipe-supporting device adapted to receive and support an exposed pipe on a building roof has a base with a substantially flat bottom for resting on a roof and an upwardly tapered structure secured on and rising from the base to provide an upwardly divergent, substantially V recess having divergent line contacts for receiving the pipe and supporting it above the base. The structure is configured to distribute the weight of the supported pipe substantially equally over the flat area of the base in contact with the roof, and the single line contacts of the V provide this substantially equal distribution of weight regardless of whether the roof is flat or sloped, or regardless of whether the pipe being supported is parallel to the roof or sloped with respect to the roof. Further, the line contacts provide a minimum of resistance to pipe movement so that pipes can easily slide on the device when they expand and contract.

Dependent claims

A pipe supporting device adapted to receive and support an exposed pipe on a roof, said device comprising a base having a flat bottom for resting on the roof;

and upwardly tapered structure secured on and rising from said base to provide an upwardly divergent, substantially V recess having divergent line contacts for receiving the pipe and supporting it above said base, said line contacts minimizing contact area and friction between the pipe and said device, and said structure being made up of wall means, parts of which divergently recede from the respective line contacts at opposite arms of the V to provide mutually opposite, upwardly tapered towers, other parts of which slope upwardly from said base toward and meeting with the lower ends of said receding wall parts between said line contacts, and still other parts of which join the receding wall parts of the respective towers, said other wall parts and said still other wall parts having lower ends forming a symmetrical periphery at said base which substantially evenly distributes the pipe load on the base and on the roof.
