Abstract
PURPOSE: To manufacture a metallic panel with no use of the welding, by inserting a joint metal between two side edges previously formed through bending three sides of two side plates made of a thin steel sheet, by engaging a folded edge of the side edge with an engaging edge of the joint metal, and by pressing the joint metal to flat.
CONSTITUTION: A crease 2 is made in each of three sides except the lower side of a thin metallic sheet 1 as a side plate; an outside part of the crease 2 is obliquely bent as the side edge 3; further, the outer edge of the side edge 3 is inward bent to form a folding edge 4. Both side edges of a metallic strip is upward bent from a crease 6 in order to prepare a joint metal 5 provided with an obliquely inward looking engaging edge 7 on both sides. A circumferential frame 8 of a channel-shaped section provided with a projecting edge 9 on both sides is prepared; the circumferential frame 8 is interposed between said two side plates 1 so as to make the side edges 3 face to each other; at the same time, the joint metal 5 is inserted between two side edges 3 in order to butt the folded edge 4 of both side edges 3 with the engaging edge 7. Finally, the joint metal 5 is pressed to flat, and a lower frame is attached to finish a metallic panel.
