Abstract
Abstract A rigid wooden composite assembly such as a beam, post or the like, includes a plurality of elongated wooden boards of varying lengths disposed in face-to-face relationship and forming a plurality of layers. At least one of the layers includes a plurality of boards, the inner ends of which abut to form a joint therebetween. A connector device has a base plate with openings therein. Prongs extend outwardly from the plate and initially generally normal thereto. The prongs of adjacent openings extend in opposite directions from the plate. The connector device is disposed between the layers so that the base plate bridges the inner portion of the joint and the oppositely extending prongs penetrate the opposing board faces. When the assembly is compressed together, the prongs deform and clinchingly engage the wood surrounding the joint. The abutting boards are spliced together, and the facing boards are held tightly together.
