L1/E lintels are designed to provide support over openings at eaves level. To achieve the loading figures indicated on the opposite page, the lintel must be built in with the blockwork as shown, and a continuous wall plate must be provided over the opening and reveals. The loading figures are achieved by using composite action of the inner leaf blockwork. Providing the maximum cavity width for the appropriate lintel is maintained the outer flange will have a brickwork bearing of 13mm. The lintels must be ‘built in’ with the blockwork positioned against the upstand of the lintel together with a continuous wall plate as shown.
