NE Lintels must have a minimum end bearing of 150mm on each side of the opening, bedded on mortar. (150mm bearing for openings below 1.8 mtr and 200mm for openings above 1.8 mtr).
The lintel should be in level along its length and across its width. Masonry built must be laid on a mortar bed and all perpendicular joints to be filled with mortar.
Temporary propping beneath a steel lintel is practised to facilitate speed of construction. Care should be taken to avoid shock loading on lintels when doing masonry work above it.
The bracket can be used for bearing of lintel when the wall is not present for bearing purpose. Mark the hole location first then make a drill using 5mm drill bit and then fix bracket by plumbing nails with flat washers.
