Abstract

630,329. Moulding concrete stairs. WELSCHEN, J. P. Jan. 10, 1947, No. 923. Convention date, Jan. 12, 1946. [Class 87 (ii)] Inner casing elements, each consisting of a step 2 and riser 3, are arranged in a supporting structure 1 in stair-formation between and in spaced relation to correspondingly stepped side plates 4 which project above and beyond the casing elements 2, 3. Transverse reinforcing rods 5 are then secured between the side plates 4 opposite the angles of the stair formation and longitudinal reinforcing wires 10 are stretched each alternately over and under the rods 5 while transverse wires 11 are stretched through holes in the side plates 4. Reinforcing tubes or rods 24 are inserted in the lateral spaces between the plates 4 and inner casing elements 2, 3, and outer casing elements 13, 18 are then secured between the plates 4 in spaced relation to the elements 2, 3 so as to leave an open space in front of each element 18 for reception of the concrete ; after casting of each step by tilting the frame 1 forwards, the open space is closed by an outer casing element 19. On hardening, the casing is dismantled, plates 4 removed and the finished staircase taken off the frame 1.
