ABSTRACT:
Apparatus for joining a sheet to a structural member angled therefrom which includes forming an indented portion in the sheet as well as a slot such that a clip having a tail section, a body section and a head section may be inserted such that the tail section extends through the slot and the head section extends beyond the end of the sheet such that the head section and the tail section are on one side of the sheet and the body section is on the same side of the sheet as the indented portion. The clip head has a screw opening such that a screw may be inserted through the member to which the sheet is to be joined into the clip head. Upon tightening the screw a support surface on the clip tail engages the sheet at the slot and the screw threads engage the interior surface of the indented portion of the sheet thereby securing the sheet to the screw and consequently the member through which the screw extends. The clip head may also have contact surfaces such that the clip body may be deformed against the indented portion of the sheet and held in a deformed stressed position by the contact surfaces thereby securing the clip to the sheet prior to the insertion of the screw. This joint has particular application for aluminum tube sheets used with aluminum heat exchangers when the tube sheets are mounted to a bracket perpendicular to the ends thereof.
