Abstract (en)
[origin: US4280308A] A lintel for supporting arches over doors, windows and other openings in a wall. The lintel is made of relatively thin sheet metal and has at least one load-carrying shank (5;12,13;19,20), so that the lintel in spite of its thin construction can carry great loads during the walling of the arch. The shank or each shank is provided with a longitudinally extending material weakening (6), e.g. a series of slots, perforations, a groove or similar. Said material weakening forms a fracture indication along which the shank can be folded or broken off, when the motar has set and brickwork has become self-supporting.
