Abstract

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.

Claims

1. A four corner joint between upper wall panels having lower ends secured to a structural member and lower wall panels having upper ends secured to the same structural member;

each of said wall panels comprising outer and inner sheet metal skins connected by an insulating core and having marginal connecting means formed along the opposite longitudinal edges of the outer sheet metal skins;

the outer and inner sheet metal skins and the core coterminate at said upper ends of said lower wall panels, the inner sheet metal skin and the core coterminate at said lower ends of said upper wall panels and confront said upper ends of said lower wall panels, the outer sheet metal skins of said upper wall panels having lapping ends extending beyond said lower ends of said upper wall panels and overlapping said lower wall panels, and said marginal connecting means being substantially entirely removed along the length of said lapping ends to preclude interfering with the interconnection of the corresponding marginal connecting means of said lower wall panels.

2. The joint as defined in claim 1 wherein said marginal connecting means comprise a tongue and a channel defining a complementary groove, and wherein along the length of said lapping ends, a longitudinal edge strip of said tongue is removed and said channel is removed in its entirety.

3. The joint as defined in claim 1 including a bead of sealant material compressed between the confronting end faces of the insulating cores of the upper and lower wall panels to provide a weathertight seal.

4. The joint as defined in claim 3 wherein said bead of sealant material contacts the inner faces of said lapping ends.
