<p>A four corner joint between wall panels of the type comprising outer and inner skins connected by an insulating core, and having marginal connecting means formed along the opposite longitudinal edges of the outer skin. The outer and inner skins and the core co-terminate at the upper ends of the lower wall panels. The outer skins of the upper wall panels have lapping ends which extend downwardly beyond the lower ends of the upper wall panels and which overlap the wall panels. The marginal connecting means are substantially entirely removed along the length of the lapping ends of the upper panels to preclude interfering with the interconnection of corresponding marginal connecting means in the lower wall panels.</p> |
