About this detail

Concrete tilt-up wall jambs and lintels require specific reinforcing layouts with vertical and horizontal bars distributed across single or double curtain configurations. Vertical jamb reinforcing extends from the bottom of the panel to the top, with half placed on each face for double curtain layers, and ties spaced at 8 inches on center above and below openings. Lintel reinforcing extends forty bar diameters minimum past the opening edge and terminates with 90-degree hooks where necessary. Single scheduled stirrups or hairpins with 180-degree returns are used at top and bottom horizontal lintels when only one bar is required. Additional hairpins and ties are installed at alternating directions and specified spacings based on wall leg widths and pier dimensions.

1. JAMB REINFORCING, INCLUDING TIES, SHALL EXTEND FROM THE BOTTOM OF THE PANEL TO THE TOP OF THE PANEL EXCEPT FOR OPENINGS LESS THAN 3'-1" WHICH SHALL BE REINFORCED PIER DETAIL . SPACE TIES AT 8"oc. FROM 2'-0" ABOVE THE OPENING TO THE TOP OF THE PANEL, AND FROM 2'-0" BELOW THE OPENING TO THE BOTTOM OF PANEL, TYPICAL. 3. HALF OF THE VERTICAL JAMB REINFORCING IS TO BE PLACED ON EA FACE OF THE PANEL WHEN DOUBLE LAYER JAMB REINFORCING IS USED. 4. 3.EXTEND LINTEL REINFORCING BEYOND EDGE OF THE OPENING 40 BAR DIAMETERS MINIMUM. WHERE NOT POSSIBLE, EXTEND TO THE EDGE OF TILT-UP WALL AND TERMINATE WITH 90° HOOK. 6. REINFORCE JAMBS AND LINTELS PER PLACEMENT DIAGRAMS, SEE CONCRETE TILT-UP PANEL ELEVATION TYPES FOR TYPICAL PANEL REINFORCING. 7. IF THE LEG OF THE CONCRETE TILT-UP PANEL IS NO MORE THAN 6" WIDER THAN THE SCHEDULED JAMB WIDTH, THEN REVISE THE WIDTH OF THE SCHEDULED JAMB WIDTH TO FIT WITHIN THE LEG OF 8. AT PANELS WITH KNOCKOUT PANELS, REINFORCE AROUND THE KNOCKOUT PANEL AS PER TYPICAL ELEVATIONS. HORIZ LINTEL REINF.
