This invention is directed to the field of architecture design for residential and commercial properties; and, in particular, to a structural bracket assembly to support cellular polyvinylchloride or similar material used in pergolas, trellises and the like structures.
Pergolas and trellises are commonly used to enhance the architectural design of a building or property. Typically constructed from wood, such structures can be free standing or wall mounted. Unfortunately, wood is susceptible to decay. Commonly the decay is dry rot. Dry rot is caused by certain fungi which grow when sufficient moisture is present, allowing the fungi to digest the wood. Besides the maintenance required for wood to keep its appeal, weakened wood is especially problematic should the structure be exposed to high wind conditions, such as tropical storms or hurricanes. Aside from such severe weather as mentioned above, routine thunderstorms and frontal systems can create localized wind gusts exceeding 100 miles per hour.
Plastics have been recognized as a substitute for wood architectural trim structures. Plastic has weather resistant qualities, can be treated to resist ultraviolet radiation, and has a surface porosity that accepts painting. However, simply substituting plastic for a wood structure is not as desirable since plastic possesses poor structural capabilities.
What is lacking in the industry is a device for support rafter tails when used with trellises and the like structures that require reinforcement.
Applicant's invention provides a structural bracket assembly for a residential or commercial trellis wherein the rafter component conceals the structural bracket. The structural bracket assembly comprises a mounting plate securable to a vertical cinder or concrete wall having a support member extending outwardly therefrom at an angle between 55° and 75° relative to the vertical wall and terminating with an end plate. The support member is between 31 13/16 inches and 44 11/16 inches long. Plywood is fastened to the top and the bottom of the support member. Roofing material is then fastened to the upper piece of plywood. A frieze board is secured to the vertical wall beneath the lower piece of plywood, and fascia is fastened to the end plate. A soffit panel is positioned between the frieze board and the fascia. The soffit panel is secured to the lower piece of plywood. A rafter tail is positioned beneath the soffit panel. In one embodiment, the rafter tail includes a wall and soffit mounted clamp for securement. In another embodiment, the rafter tail is spaced apart from a decorative support bracket by a decorative cross beam.
Modern buildings made of cinder block or cement block provide an alternative to conventional rafter tails. Conventional rafter tails are a major component of the soffit system in timber frame construction. Rafter tails can be used to emulate traditional timber frame construction. Some of these vernaculars or styles are Coastal, British West Indies, Dutch Indies, Cape Cod, New England, Key West, Charleston, Spanish Mediterranean, Colonial, Low Country, and Craftsmen style homes, which all prominently use wood rafter tails, wood corbels, and wood bracket detailing.
A method of manufacturing architectural components such as rafter tails may be found in Applicant's Patent Registration U.S. Pat. No. 9,388,587, the contents of which are incorporated herein by reference. Said rafter tails are constructed of free foam Cellular PVC which can be formed into a limitless a number of shapes and sizes. PVC rafter tails have many different characteristics that improve the life, looks, and longevity of an exterior rafter. PVC rafter tails are impervious to moisture, mildew, rot, cracking, warping, and insects or pests.
An objective of the invention is to provide a wall mounted trellis capable of structural support, as well as withstanding high winds and storm conditions by use of a concealed aluminum wall support member.
Another objective of the invention is to provide architectural trim components that can be manufactured using materials and techniques that create a structural support that will not rot, crack or warp, and is otherwise weather resistant.
Yet still another objective of the invention is to provide an architectural trim that is hollow, making it lighter and easier to install versus wood or solid plastic trim.
Another objective of the invention is to provide an architectural trim product that looks the same as traditional architectural trim made from wood yet eliminates all the problems associated with wood.
Still another objective of the invention is to provide a process that allows manufacturing of cellular PVC components to create an unlimited combination of shapes and sizes from sheet goods of varying thicknesses.
Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of this specification, include exemplary embodiments of the present invention, and illustrate various objects and features thereof.
Although the invention will be described in terms of a specific embodiment, it will be readily apparent to those skilled in this art that various modifications, rearrangements, and substitutions can be made without departing from the spirit of the invention. The scope of the invention is defined by the claims appended hereto.
