Creagh Concrete Prestressed Wall Panels are delivered flat on the lorry bed/trailer separated by stacking timbers. The spacing of these timbers is designed for maximum protection of the panels and to minimise the effects of the camber.
1. Using certified wire rope/chain lifting shackles and straps, the panels are lifted from their stack by the holes cast near the upper side.
2. The units are placed and centred against the columns then secured using the steel fixing clips - FSA expanding bolts. Alternatively the panels may be fixed within the columns against either flange and held in place with a retaining angle.
3. The panels can rest on the floor slab as no special foundation is required or can be seated on suitable landing cleats.
4. A soft pacing should be used between cleat and panel where the bay length exceeds 4.5m or the height 3m.
5. Adjoining panels are erected similarly leaving a 10-20mm gap between units at the centre of the column. Panels are lowered male joint uppermost on to the panel below.
6. The panels are sealed after they have been installed . Where a water tight seal between the bottom panels and floor is required. the panel can, in some circumstances, be concreted into the floor with a top seal between the outside of the panel and the concrete ensuring a waterproof joint.
7. Alternatively a kerb can be cast to the back of the panel having a compressible packing topped with sealant between the two allowing the panels to deflect under load. The advice of Creagh Concrete should be sought in each case.
