ABSTRACT:
This structural member is an elongated extruded part having a cross-sectional contour including a stitching leg adapted to be deformed together with the margin of an adjacent panel, so as to connect the member and the panel. The structural member disclosed is channel-shaped and has two stitching legs, one on either side of the channel. Each stitching leg cooperates with a wall of the channel to define a slot for receiving the margin of a panel. After the panel margin is inserted in the slot, the stitching leg and the panel are deformed together to connect the panel and the member. Two extruded structural members may be connected with two panels to form a box beam of hollow rectangular cross-section. Other polygonal cross-sections may be formed by connecting alternate extruded members and panels, with appropriate angles at their interconnections.
