Contained load transfer device for wood sheathing products and roof construction method therewith

Abstract

The utilization of a specific load transfer device for the purpose of allowing for reliable connection and adhesion of composite wood boards during edifice manufacture therewith is provided. Such a device is configured for containment within slots cut into the peripheral edges of such wood boards and cut into a shape therein that is complementary to that of the device itself. In such a manner, the device, when introduced within the properly shaped slot, permits separation of adjacent wood boards that are sequentially applied to the frame of the target edifice, as well as, ultimately, sufficient load bearing strength for the overall construction (such as a roof) within which such connected wood boards are utilized. The separation of wood boards thus permits proper sealing therebetween (with tape, sealant, or other like material) as well as proper distance for shrinking or swelling (due to moisture / temperature variations) to be taken into account during the lifetime of the edification (thereby permitting expansion as needed). The ability to impart increased load bearing strength thus allows for an increase in construction materials (in number and in weight) to be carried and kept on such a structure during construction as well. The method of manufacture of an edifice utilizing such load transfer devices between wood boards is also encompassed within this invention.

AI Technical Summary

Benefits of technology

The invention is a load transfer device that allows for reliable connection and adhesion of composite wood boards during roof construction. The device is designed to be inserted into slots cut into the peripheral edges of adjacent boards and does not contact the top or bottom of the boards. This allows for proper sealing and compensation for changes in moisture content during the lifetime of the roof. The device also allows for the application of materials via adhesion to adjacent boards without losing the effectiveness of the adhesive material. The invention provides a simple and effective way to connect building roof component wood boards together during construction.

Problems solved by technology

Such clips, known in the industry as H-clips, exhibit disadvantages, however, that render them highly undesirable for such a purpose.

For instance, such H-clips make it difficult to apply adhesive tape (for, among other purposes, sealing seams to prevent water penetration therein and air leaks) along the spaces between boards conjoined by such clips, particularly since such clips are applied to the exterior of such boards.

The adhesive tape applied to such boards must thus be in contact with such clips as well as such boards, thereby exhibiting a certain reduction in potential adherence thereto and compromising the effectiveness of such tape (or like adhesive material).

Also, it has been problematic to apply certain load forces to roof structures including such H-clips, particularly during manufacturing steps thereof, as such clips exhibit a propensity for disengaging upon application of excessive weight on certain portions of component boards.

To date, the wood board roofing component industry has not been accorded such an improvement.
