Definitions
- This invention relates to moulds for casting concrete or other cementitious components.
- the invention is particularly although not exclusively applicable to moulds for casting arcuate concrete tunnel lining segments.
- This invention provides a mould for casting concrete or other cementitious components, the mould having a mould surface and electric heating means embodied in the mould adjacent the surface to heat the surface and thereby a component being cast in the mould to accelerate curing of the component.
- the temperature of the wet concrete can be raised to achieve a more rapid curing of the concrete and thereby similar time for stripping of the cast concrete components from the mould as with the use of steam.
- the advantages over the use of steam are that there is a relatively inexpensive energy consumption, no extra randling arises as the mould remains static. Working conditions remain relatively clean as there is no possibility of steam condensation affecting the working area.
- the cost of wiring and associated control equipment is substantially less than the cost of steam plant and the steam chamber.
- the invention also provides a mould for casting a concrete or other cementitious component having a device acting on the mould for applying vibration to the mould to consolidate the concrete or other cementatious mix in the mould, a chamber enclosing the vibration applying device and engaging the mould around the location where the device acts on the mould and a means for creating a vacuum within the chamber to minimize transmission of noise from the vibrating device.
- Figure 1 is a side elevation view of a mould for creating arcuate concrete tunnel lining segments
- Figure 1 is a plan view of the mould illustrated in Figure 1;
- Figure 3 is a plan view of a production area showing typical mould layout.
- the base 10 of a mould for forming arcuate concrete tunnel lining segements having a mould cavity indicated at 11 formed in its upper surface and extending between ends 12 of the base.
- the cavity has an upwardly facing convexly curved mould surface 13 extending between the ends 12 to define the inner surface of the segment to be cast and the inner sides of the ends 12 are formed with mould surfaces 14 to define the circumferential ends of the segment to be cast.
- An electrical heating element 15 is cast into the body of the base 10 and extends through a number of closely spaced turns in a zig-zag pattern parallel to and just below the mould surface 13 throughout the length of the mould surface. Equally the heating element could follow a zig-zag path across the width of the mould.
- the ends of the heating element 15 terminate in a junction box 16 built into a side wall of the base 10 adjacent the center of the base (or at any other convenient location on the base) and are connected by leads 17 to a control box and power source (not shown).
- a thermostat unit 18 is counted on the junction box 16 to project into the thickness of the base and is connected by leads 19 to a thermostat control for the power source to the leads.
- mould surface 13 can be heated during casting of a concrete segment in the mould to raise the temperature of the segment and thereby accelerate the curing of the segment in the mould.
- Figure 3 illustrates the layout of a production area in which a number of rows of moulds 10 are mounted parallel with one another along the length of the workshop area with four moulds in each row.
- the moulds in each row are connected to a common control box along one side of the production area and the control boxes 20 are all interlinked to a common power supply.
- each cover plate is of hollow construction comprising inner and outer plates 26, 27 spaced by frame members 28 and a port 29 is formed in the outer surface for a connection to a vacuum supply.
- the inner plates 26 of the covers are formed with a multiplicity of apertures through which vacuum can be drawn to assist in extracting air from the surface of the concrete to improve the final surface finish of the segment.
- vacuum boxes 31 are fitted to the mould over the vibrators to engage the mould around the vibrators each box having a conduit 32 leading to a vacuum pump to draw vaccum within the box.
