ABSTRACT:
A corner joint formation for pre-shaped building logs of the type in which the flanks of a notch in the top of one log fit against the sides of a neck formed by a notch in another log forming a corner with the first log, wherein the mating side faces of the neck and notch are tapered so as to fit closely together when the logs are fully engaged. The tapered flank faces of the notch stand proud of an outer shoulder which conforms closely to the outline sectional shape of the mating log and forms an interference fit with a similar shoulder of this mating log. The neck of the joint formation is preferably ridged to inhibit flow of water across the joint, and in addition a weather strip may project from the upper edge of the neck ridge to inhibit flow of air across the joint.
