Roofing structures can be constructed using a number of different methods and roofing systems. One system, commonly used for retrofit roofs, is the post and purlin system which includes a plurality of vertical posts connected to the existing roof system. Connected to an upper end of the vertical posts are horizontal purlins that run perpendicular to the vertical posts in the horizontal plane. Various roofing components can be connected to the purlins.
Sub-structural framing assemblies can be used to support the construction of a new roofing system over an existing roofing system. However, existing framing assemblies suffer many disadvantages, such as, for example, 1) an inability to vertically adjust the height of the framing assembly, and/or 2) an inability to freely rotate a portion of the framing assembly to provide a desired pitch and/or slope of the new roofing system.
Non-limiting examples of prior art framing assemblies are present in U.S. Pat. Nos. 5,875,592; 7,918,054; and US 2001/0025458, which are all incorporated herein by reference.
In view of the prior art, there remains a need for an improved framing assembly having a vertically adjustable height, having a free pitch rotation, and which can support exterior building roofing materials over an existing roof.
The present invention is directed to an improved apparatus and method regarding the creating of sub-framing for a roof, more particularly to a framing assembly, particularly to framing assemblies for roofing systems, more particularly to a sub-structural framing assembly capable of providing support for a new or retrofit roofing system over an existing roofing system of a building, even more particularly to a sub-structural framing assembly capable of providing support for a new or retrofit metal roofing system over an existing roofing system of a building, and still even more particularly to a sub-structural framing assembly capable of providing support for a new or retrofit sloped metal roofing system over an existing roofing system of a building. Generally, this improved framing system can be used on new or retrofit roofing projects requiring a stable and flexible sub-framing.
In accordance with a non-limiting embodiment of the present invention, there is provided a framing assembly which can be connected to the existing roof structure of a building, and which can be configured to provide structural support for one or more exterior building roofing materials, wherein the exterior building roofing materials are part of a new roofing system. The sub-structural roof construction component can also or alternatively be configured to allow for standard components designed and manufactured in a factory to be installed at a jobsite. The sub-structural roof construction component can also or alternatively be configured to accommodate variations required in the field. The sub-structural roof construction component can also or alternatively be configured to be adjustable in the field for height and/or can be configured to be rotatable to fit the customer's roof design slope.
In another and/or alternative non-limiting aspect of the present invention, there is provided a framing assembly having a top shaped element, a first vertical web element, a second vertical web element, and a base plate element.

In one non-limiting arrangement, the top shaped element is pivotally connected to the first vertical web element by a rotational connection element (e.g., bolt, rivet, pin or other structure); however, this is not required. The top shaped element can also include a securing element that is spaced from the rotational connection element and is configured to secure the top shaped element in a specific position relative to the first vertical web element so as to inhibit or prevent rotation of the top shaped element relative to the first vertical web element. As such, when the top shaped element is pivoted about the rotational connection element to a desired rotation position relative to the first vertical web element, the securing element can be used to maintain the top shaped element in such position. If the top shaped element needs to be rotatable adjusted, the securing element can optionally be configured to allow the top shaped element to be rotated relative to the first vertical web element and then resecure the top shaped element in the adjusted position.
