These patents are hereby incorporated by reference.
A representative number of these patents will be reviewed in the following discussion:
U.S. Pat. No. 3,760,544 issued to Hawes et al. on Sep. 25, 1973, discloses a SEALING GASKET WITH ELONGATED INTERNAL STIFFENER. This specification is directed towards an extruded plastic gasket which is constructed with a full length of strip or insert of a different material in the gasket. This inner material is utilized to strengthen the portion of the gasket in which it is located and reduce any creeping or other movement of the gasket after it has been installed.
U.S. Pat. No. 3,952,461 issued to Kinsey on Apr. 27, 1976, discloses MULTI-LAYER WALLS FOR FRAMELESS BUILDINGS FORMED FROM EXTRUDED ALUMINUM OR PLASTIC INTERLOCKING WALL ELEMENTS.
FIG. 20
of this application describes the use of a sub-comb having upwardly facing, angularly disposed surfaces for engaging and supporting the upper ends of the metallic roof rafters. As noted by the remainder of the specification, the specification is directed towards a multi-layer wall structure which utilizes so extruded wall elements to interlock and form a frameless multi-story building complex.
U.S. Pat. No. 4,601,139 issued to Esposito on Jul. 22, 1986, discloses a METHOD AND FRAMEWORK FOR A GREENHOUSE OR THE LIKE INCLUDING A REVERSIBLE GABLE ADAPTER. As noted in
FIG. 8
of the drawings, wedge-shaped adapters is utilized to join vertical bars with sloped bars. This adapter is inserted into a chamber using the prong of the adapter.
U.S. Pat. No. 5,046,791 issued to Kooiman on Sep. 10, 1991, discloses an Extrusion Frame and Components Therefor. This specification is directed towards the framing of cabinetry and the like which utilizes a connecting element for joining extrusion frame components.
U.S. Pat. No. 5,325,647 issued to Forry et al. on Jul. 5, 1994, discloses a Composite Ceiling Grid. This specification is directed towards ceiling grid runners and the associated method of assembly which utilizes metal reinforced thermal plastic compounds. This system utilizes the metal in strategically positioned areas to maximize the strength ratio of the plastic.
U.S. Pat. No. 5,555,681 issued to Cawthon on Sep. 17, 1996, discloses a Modular Building System. This specification is directed towards the construction of various light structures. An octagonal cap is described which may be separated to serve as an Apex for a quarter-end structure for a shed like addition. As shown in
FIG. 13
of the drawings, a roof ridge member may be used to form the roof ridge or crest of a gabled structure.
U.S. Pat. No. 5,792,529 issued to May on Aug. 11, 1998, discloses a Reinforced Plastic Extrusion. This specification describes the use of three different extrusions in order to form a single configuration with increased components strength and stiffness. Thus, the desired profile is extruded which allows for the strategic placement within a profile to obtain optimum strength and stiffness.
Prior art aluminum roofing systems for additions or sunrooms are well known. These sunrooms pose certain problems during their life. Aluminum works as an excellent heat conductor as evidenced by its use in a variety of heat dissipation applications. However, this high thermal conductivity causes several problems in roofing systems. Aluminum roofing systems transfer cold from the outside of a structure to the interior environment. This heat transfer can lead to condensation on the interior roof of the structure, and the transfer of interior heat to the outside environment results in thermal inefficiencies. In addition, aluminum structures are rigid and may dent, scratch, or be punctured due to contact with normal everyday items such as lawn mower, foot traffic, or wind blown debris. Thus, the present art of aluminum roof construction has several disadvantages. can lead to condensation on the interior roof of the structure, and the transfer of interior heat to the outside environment results in thermal inefficiencies. In addition, aluminum structures are rigid and may dent, scratch, or be punctured due to contact with normal everyday items such as lawn mower, foot traffic, or wind blown debris. Thus, the present art of aluminum roof construction has several disadvantages.
Thus, the prior art patents teach limited structures which pose problems for temperature variations, normal wear and tear associated with buildings, and long term stability. What is needed, then, is an improved method and apparatus for constructing buildings with increased efficiency.
SUMMARY OF THE INVENTION
The present invention is directed towards a vinyl roofing system utilizing beams to inter-connect roof panels with a roof cap for providing a roof structure. The system may utilize a connecting spider for forming rounded roofing systems, and an upper and lower roof cap for connecting the roofing system together. The system may utilize channel beams with top and bottom plates with a plurality of vertical members to form a center aperture. This center aperture may be utilized with a beam filler, and may also be utilized as a raceway for electrical, water,
