Roof vent support arrangement

DETAILED DESCRIPTION Turning now to the drawing, attention is directed to FIG.
1 which illustrates a vent support arrangement which is constructed in accordance with the present invention and which is generally designated by the reference numeral 10.
Arrangement 10 is shown assembled in place in a roofing structure generally designated by the reference numeral 12.
The roofing structure includes a roof deck 14 and may include a built-up roof 16 comprised of, for example, roof insulation 16a and a roof membrane for flashing 16b located directly over the deck and/or other components, as is well known.
The overall roof structure including the deck and bult-up roof as shown extends horizontally.
However, it should be understood that this structure could be sloped.
A vent pipe generally designated by the reference numeral 18 extends through the roof structure from the underside of the latter through an opening in the structure, indicated at 20, and terminates well above the top surface of the structure.
Vent support arrangement 10 includes a roof deck connector 22 and a vent connector 24.
As will become more apparent hereinafter, these components cooperate with one another to provide an uncomplicated and economically produced vent support arrangement which can be easily assembled into a new or existing roof structure and which can be readily connected to a new or existing vent extending through the roofing structure, as illustrated in FIG.
1.
It will also become more apparent hereinafter that these components, i.
e.
, the deck connector and vent connector, cooperate in a way which allows the arrangement to be assembled in place regardless of reasonable variation in the thickness of the bulit-up roof, without the necessity of additional components or unreasonable modification to either the arrangement or the vent.
In addition, the vent support arrangement constructed in accordance with the present invention provides for a reliable seal between the vent and the roofing structure taking into account relative movement of the two due, for example, to settling of the building and/or high winds
