Claims12
A wall panel system, comprising:
- a first wall panel having a first core with skin adhered to outer surfaces of the first core and having a first end;
- a second wall panel having a second core with skin adhered to outer surfaces of the second core and having a rabbet joint at an end for receiving at least a portion of the first end of the first wall panel;
- an interior corner flange having three portions forming a T shape, a first and a second of the three portions each having an interior corner exterior surface and panel skin surface, a third of the three portions having a transverse length equal to or less than either or both of the first and second portions;
- such that the skin surface of the first portion of the interior corner flange contacts the first panel skin and the skin surface of second portion of the interior corner flange contacts the second panel skin;
- and
- wherein the third portion of the interior corner flange extends into the rabbet joint and is sandwiched between a portion of the first panel and a groove of the rabbet joint.

A sandwich panel corner joint, comprising:
- a first and second sandwich panels each comprising a core having two wall surfaces, two ends, and a rigid skin structurally coupled to each of the two wall surfaces;
- a rabbet joint formed in the first panel along an end comprising two end portions and a flange portion, the two end portions each defining a groove surface formed a first axial distance from the first panel edge and a first depth from a skin surface, and the flange portion defining a flange groove surface formed at a second, longer axial distance from the first panel edge;
- an interior corner flange having an axial length less than or equal to a length of the first panel end surface, and having three portions forming a T-shaped cross section;
- the first and second portions of the interior flange each having an exposed corner surface and a skin surface opposite the exposed corner surface, the skin surfaces each comprising at least one channel along the axial length;
- the third portion of the interior corner flange having a thickness T, a rabbet groove surface, and a skin surface, the third portion having a transverse depth that is equal to or less than a depth of the flange groove surface;
- wherein when the first panel, second panel, and interior corner flange are assembled in operative manner, the third portion of the interior corner flange extends into the flange portion of the rabbet joint.
