Description
- This invention relates generally to the field of construction and more particularly, but not by way of limitation, to apparatus and method of forming a curved structure, such as curved walls or archways, barrel ceilings and round columns.
- straight walls are typically constructed using a runner attached to the floor structure, a runner attached to the ceiling structure (or free floating) and studs positioned between and attached to the runners. The runners and studs form a structural frame to which gypsum board, such as SHEETROCK™, or other wall covering can be attached. The same principles generally apply to construction of other straight structures. The runners and studs are often formed of wood, such as 2x4's and 2x6's (approximate dimensions of boards in inches). Steel runners and studs are also used, especially in commercial construction as well as in some residential construction.
- It is often desirable to construct curved structures, such as curved walls or archways, barrel ceilings and round columns. The principles for constructing curved structures are much the same as those for constructing straight structures except that the runners must form a curved shape.
- Various products and methods have been used to form curved structures. One such product is demonstrated in a brochure entitled "The Flex Track™ System," which is incorporated by reference herein, sold through Flex Trim Group, a subsidiary of Burton Creek Industries, located in Bedford, Texas. This product consists of two flexible L-shaped brackets which together comprise a flexible runner to which studs can be attached. However, due perhaps to the product's design and/or flexibility, the strength of a curved structure formed using the Flex Track™ is inadequate.
- A method of forming a curved wall is also illustrated in U. S . Patent No. 5,291,717 to Turner Turner teaches the use of a tabbed support bracket as a runner. This produces a flimsy curved structure and provides no method to lock or fix the radius of curvature.
- Another method of constructing a curved wall and an apparatus for performing this method, the apparatus comprising all of the features of the preamble of claim 1, are shown in a U.S. Gypsum Company brochure entitled "Interior Remodelling Systems", 1987, XP002912702. The method involves cutting the leg and web sections of a standard steel runner at intervals for the length of the arc. Next, a steel strip is placed inside both runners and attached with fastener. The runners are then secured to the floor and ceiling structure and studs are fastened to the runners. This method provides adequate strength but is labor-intensive and costly, especially in a commercial setting since many cement-piercing nails must be used to secure the runner to a concrete foundation.
- US-A-3,053,358 provides apparatus for forming a curved structure in accordance with the pre-characterising portion of claim 1. It discloses a connector for connecting two straight lengths of cable way at a desired angle.
- US-A-4,894,962 discloses a structure formed form a plurality of members each comprising an elongate beam with a fixture at each end. The fixtures of neighbouring beams maybe pivotally connected together to provide a flexible array of parallel beams, and the structure is tensioned by respective wires passing through the fixtures at each end of the structure.
- There is a need for improved apparatus and methods of forming a curved structure which provide adequate strength, minimal labor requirements, cost efficiency and flexibility in application.
- The present invention provides improved apparatus and methods of forming a curved structure which meet the needs described above.
- According to the present invention there is provided an apparatus for forming curved structures as defined in claim 1.
- The invention also provides a method of forming a curved structure comprising providing the structure above as a first runner and a second runner.
- The present invention provides a strong curved structural support for various applications even when one runner is "floating", i.e., not attached to a structural support such as a ceiling joist. Furthermore, the present invention provides a quick, easy and cost-efficient method of constructing such a curved structure.
- It is therefore a general object of the present invention to provide improved apparatus and methods of forming a curved structure. Other and further objects, features and advantages of the present invention will be readily apparent to those skilled in the art upon a reading of the following disclosure when taken in conjunction with the accompanying drawings.
