Definitions

  • the present invention relates to a process for manufacturing concrete roof tiles.
  • a process for manufacturing concrete roof tiles without the use of curing moulds comprising the steps of metering concrete mix into a tile mould, applying pressure to the mix in the mould both to form an uncured tile having a thin, non-planar shape which nevertheless permits packing of the tiles to form a substantially solid block of tiles, and also to dewater and deaerate the mix and give an uncured tile containing the water required for hydraulic curing, removing the uncured tile from the mould, and loading the tile into a support frame; the steps being repeated, and the loading being carried out with the repitition of the steps, so as to form a virtually solid block of uncured tiles on the support frame; and curing the tiles, or allowing the tiles to cure, while in the form of the solid block.
  • This invention is particularly directed to improvement upon the processes, already in existence, for manufacturing thin concrete roof tiles. It can totally eliminate the need for curing pallets in the curing or hardening processes.
  • the tiles usually have exactly complementary upper and lower surfaces, thus permitting their being stacked face-to- face whilst still fresh, optionally separated by a fine film of paper or other products, to form a solid block of concrete without gaps, which, once enclosed in a support-case or frame of the same shape as the outside part of the concrete blocks, permit that this can withstand the following transportation and curing processes without the tiles within suffering any damage.
  • the tiles Once the protecting support-case has been removed, the tiles remain in a block during all the following stages of stacking in the yard and transportation to the building site.
  • the principle objective of this invention is the improvement in the existing systems of mass-production of concrete tiles.
  • Figure 1 is a diagram of a conventional tile making process.
  • the proposed invention seeks essentially to reduce radically these costs, basing itself on the substitution for the above described stages of the previous manufacturing process, of a system of solid block formation and continuous curing chamber; the only auxiliary equipment being the support-cases, as illustrated in Figure 2.
  • Figure 2 is a diagram of tile making process of the invention.
  • Figure 3 is an example of the process of the invention.
  • Figure 4 is an example of a press employed in the present invention.
  • Figure 4 can be seen a rotating press of 5 stages, in which four tiles are produced in parallel simultaneously.
  • FIGS 5 to 8 illustrate solid blocks formed during the process of the invention.
  • This invention offers very important advantages over the conventional systems of concrete roof tile production already in existence. These are listed below.
  • the present invention is further illustrated by the following non-limiting example.
  • Figures 9 to 12 show a tile made by the process of the invention
  • Figure 12 illustrates the steps in the process of the invention.
  • a wet concrete mix was prepared using 1 part by weight of cement, 2 parts by weight of sand (mesh size:on 2 mm, pass 3 mm) and sufficient water to give a plastic consistency.
  • the mix was then metered into 4 lower moulds arranged in side-by-side relationship across a conveyor belt.
  • the 4 moulds formed part of a continuous array of moulds extending the length of the belt. This metering and the subsequent stages are shown illustratively in Figure 12, with each part of Figure 12 showing a stage through which each mould passes on the belt.
  • the 4 moulds under consideration left the metering station and reached a pre-forming station, where an upper forming mould was applied to each lower mould to shape the wet concrete mix to give a.preformed tile having the shape shown in Figures 9 to 11.
  • the preformed tile was slightly undersize.
  • the moulds were then advanced to a surface treatment station, where a pigmented coating of a semi-dry concrete mix containing fine sand, cement and other additives was applied to the tiles through an overhead sieving device. Thereafter with advancement to a pressing and dewatering station a high pressure of between 50 and 120 kg/cm 2 , usually 80 kg/cm 2 , was applied to the preformed tiles in the moulds. In this manner air and excess water was expressed from the tiles, and drained off through filter openings provided for this purpose.
  • the belt was then advanced to a demoulding station, where a vacuum-assisted lifting head with a shape complementary to the top of the tile served to remove the tiles from the four moulds and transfer them to a support frame.
  • the support frame comprised a base and a rear wall at right angles, with the base being supported such that the top of the rear wall was inclined rearwardly at an angle of about 10° to the vertical.
  • the support frame When the support frame was full, it was transferred to a curing chamber and the tiles cured for 2 to 6 h, say 4 h, at about 50 0 C and at about saturation lumidity. Thereafter the tiles were unloaded from the support frame, moved to the factory yard, left about a month for curing to complete and were then ready for transportation as the block, Each cured tile was about 42 cm long, about 33 cm in breadth, and about 1. 2 cm in depth.
