Abstract

620,750. Moulds for concrete beams. CONCRETE PILING, Ltd., MALCOMSON, J. C., and WALSH, J. M. Oct. 17, 1945, No. 27283. [Class 87 (ii)] [Also in Group X] Beams for concrete floors &c. (see Group X), are moulded in apparatus containing a number of moulds each of which consists of a base 16, spaced from its fellows and supported on cross beams ; side walls 18 shaped to give the required profile; and end walls 19 which fit into slots in the side walls. The side walls for the whole assemblage of moulds are secured by double wedges 20'between an angle member 21 on a supporting cross beam and a spacer block 22. A hollow core, e.g. a galvanised iron tube 23, is located in each mould in circular holes in the end walls, and the cores are coupled by their handles .24, adjustable hooks 25 and a bar 27 to a winch 30. The moulds and cores and lower reinforcing rods in the mould space having been assembled, concrete preferably of a relatively dry mix is placed nearly to the top of the cores and the moulds are vibrated. A strip of strong paper may then be placed along the wres, the top reinforcing rods positioned by cross wires and the moulds then completely filled and vibrated. It is stated that the cores may then be immediately withdrawn. Where the beams are required to have solid ends, the core length within the mould is reduced and the core end closed by a plug supported by the end wall.
