Abstract

1,221,973. Moulding staircase units. CONCRETE Ltd. 26 April, 1968, No. 20069/68. Heading B5A. [Also in Division E1] A staircase unit 10, Fig. 2, comprises first and second stair flights 11, 12, a landing portion 13 between the top of one flight and the foot of the other, and a spine wall 14, interconnecting the two flights. The unit is cast in concrete in the multi-part mould 16 shown in Fig. 4 and including stair forming cavities 20, 38, offset landing cavities 30, 40 and spine forming cavity formed by a base 18, 28 and formwork 27, 35, 36, 37. The plate 28 and the shutter 25 form a unit which is pivoted at 73, Fig. 11, and movable by a ram 78. The shutters 36, 37 are L-shaped and are carried by pivoted brackets connected to piston-rods of rams actuation of which effects movement of the shutters between operative and inoperative positions.
