Wembley Stadium designers have achieved a world first by fi xing precast landings into the slipformed concrete cores. A hybrid of Halfen's 38/23 highload toothed channel was factory-supplied suspended from Kwikastrip units housing T16 bars at 100mm centres. A shelf angle was subsequently secured back to the channels using a toothed T-head bolt, and the Kwikastrip bars were then bent out and the precast landing bedded into position on the angle. The structural topping poured onto the landings also filled the wall rebate created by the Kwikastrip case, to complete the joint.
