PowerBox Steel Lintel Installation

PowerBox Lintel
Installation Instructions

1. Lay wall to required height and opening.
2. Set Lintel on block with 8" of bearing each end, minimum 4" - see GSN #5.
3. Apply bed joint on front and back of block. Apply head joint on end of block.
4. Place Lintel on block level and square. Proceed as needed with the next course of block.
5. Shore Lintel as required to compensate for dead load deflection on non cured masonry and grout.
6. Shore lintel prior to laying block and grouting.
7. It is recommended to shore lintel in the middle of spans greater than 8'-0" and less than
   15'-0". On spans greater than 16'-0" use 2 shores spaced equal distance apart at approximately 5'-4" spacing. On spans greater than 16'-0" place shoring at 8'-0" centers. Make sure shoring is square to Lintel and secure. Make sure shoring supports the entire
   width of the bottom of the Lintel. (see Shoring Detail)
8. Rod grout adequately to ensure consolidation of grout (no air pockets)
9. Place top #5 rebar grade 40 Set 1.5" from top of all Lintel designs and in some cases in the bottom of the Lintel as shown on Load Tables. (see Rebar Detail)
