Panel joint

A panel joint for joining a metallic panel member to a non-metallic panel member, comprising:

• an upstanding non-metallic panel member having first and second major opposed surfaces, and a side edge which defines first and second upstanding outside corners at the intersections of said side edge with said first and second major surfaces, respectively,
• an upstanding metallic panel member including a right angle bend having first and second leg portions which define inside and outside corners at their intersection, with said inside corner being nested against the first outside corner of said non-metallic panel member,
• a metallic joining member including a right angle bend having first and second leg portions which define inside and outside corners at their intersection, with said inside corner being nested against the first outside corner of said metallic panel member,
• a plurality of openings and elongated slots in the first leg portions of the metallic panel member and joining member, respectively, with each opening in the metallic panel member being aligned with a slot in the joining member, each of said slots having first and second ends, and a longitudinal axis which extends therebetween,
• and a plurality of spacer members fixed to the first surface of said non-metallic panel member, with each spacer member projecting through an opening and an aligned slot of said metallic panel member and said joining member, respectively,
• said slots in the joining member having their longitudinal axes oriented such that a predetermined vertical movement of said joining member provides a camming action between the slots and spacer members which causes the second leg portion of the metallic panel member to be tightly clamped between the second leg portion of the joining member and the side edge of said non-metallic panel member.
