Joint for sheet elements
Abstract
Abstract A structure formed of at least two sheet elements, each having a joining section, with the joining section of the first element superposed over the joining section of the second element. The joining section of the first element has an open substantially complete and uniformly cross-sectioned longitudinally extending channel whose inner maximum width is greater than the opening of the channel insert and the joining section of the second element has a channel insert at least partially received in the channel of the first element to form an assembly of the elements. A clamping plate is positioned in the channel of the assembled elements to provide transverse clamping pressure between the wall of the channel insert and the walls of the channel of the first element. The clamping plate is a generally oblong body formed with two diagonally opposed rounded off corners, the greatest width of the plate not exceeding the width of the opening of the channel and the length of the plate being greater than the maximum inner width of the channel of the assembly before the plate is positioned in the channel, the plate providing the transverse clamping pressure when the length of the plate extends transversely of the channel of the assembly.
