ABSTRACT:
A spline for joining wood boards or panels with a groove extending throughout their longitudinal sections. The spline has a body with an upper surface and a lower surface, and central concave ridges on the at least one of upper and lower surfaces for draining water. The ridge extends throughout the length of the spline so that when two adjacent boards or panels are joined by the spline, the space between the boards or panels or equal to the width of the ridge. The spline has been designed to provided efficient drainage of water, thus preventing and substantially limiting swelling, if any, of the boards. The spline of the present invention provides a joint with mechanical and resistance properties comparable to conventional tongue and groove boards.
