Abstract
The prefabricated composite block is used as a permanent former in the construction of reinforced concrete beams and slab floors. The blocks fill the voids between beams and realise a finished plane soffit. Each unit has a parallelpiped block (P) of foamed plaster or expanded polystyrene which is bonded onto a rigid plaster base slab (S'). The base slab projects (T) on both sides, and the projections form the half soffit of the floor beams. A trapezoidal channel (R) may be formed in the re-entrant between the projections and the slab side wall and keys the unit to the concrete floor structure. The moving bands of individual conveyor belts form each mould face. Two in line moulds may be incorporated. The first forms the base slab with top striations (Q'). The second adds the web of foamed plaster or preformed expanded polystyrene.
