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.
