Abstract

1391008 Extruding concrete slabs SPIROLL CORP Ltd 7 June 1972 [7 June 1971] 26574/72 B5A A concrete slab having bores and longitudinally extending reinforcement rods 19, is extuded on to a pallet from the rectangular downstream opening 8 of a chamber 7 mounted to a wheeled carriage 3 which is propelled along the pallet by the thrust of the concrete being extruded from the opening 8 by a plurality of augers 9. At their upstream ends the augers 9 are partly surrounded by interconnected shields 17 between which the reinforcements 19 are manually fed, through the upstream end wall 11 of the chamber to which they are each guided at an upward inclination along an upwardly inclined tube 18, or a series of spaced apart tubes or rings. The extruded slab is cut intermediate successive reinforcement lengths. The augers have cylindrical ends 15 to define the bores in the concrete, are driven by chain transmission 12 from an electric motor 13 via a gear-box 14, and have hollow interiors containing vibrators driven by motors 16 in alignment with the auger drive shafts 10.
