Definitions

  • the invention relates to paving, and is particularly concerned with creating a paved area comprising a regular pattern of slabs of identical or similar shape, each slab being formed with a pattern of paviours on its upper surface so that the slabs can be laid together to form an apparently irregular pattern of paviours.
  • the pattern may either be a "random coursed" pattern in which paviours appear to extend in rows, with paviours having different dimensions in the direction along the row, or the pattern may be a "random" pattern with no apparent ranks or files of paviours .
  • the invention also relates to a mould for manufacturing slabs which are to be used to create said paved area, and to a method for producing such a mould.
  • the invention further relates to creating an irregular pattern of paviours in pattern imprinted concrete, and more particularly to a textured mat for performing the imprinting.
  • slabs are available in a variety of shapes and sizes, most are moulded to standard rectangular shapes and are produced in a range of sizes.
  • Slabs typically have one face which is intended to be visible when the slab has been laid, which will be referred to as the upper surface .
  • the upper surface can be coloured using concrete dyes which usually contain a metal oxide, and may be textured to resemble natural stone, tiles, or given other surface effects.
  • Regular and repeating patterns of small paviours such as herringbone and basket weave are common in paved areas .
  • larger concrete slabs can be moulded to have an upper surface which has the appearance of a number of repeats of the regular pattern of paviours .
  • monolithic concrete areas may be preferred. Without decorative treatment however monolithic concrete areas are usually considered to be drab, functional surfaces.
  • the most popular decorative treatment is pattern imprinting, and the resulting monolithic concrete areas are known as pattern imprinted concrete .
  • a specific concrete mix is used for pattern imprinted concrete, wherein the mix comprises small size aggregate and fibre reinforcement.
  • Imprinting is performed using textured mats usually of metal or plastic.
  • the mats are usually modu-lar such that a series of mats is used to generate the pattern of paviours in the concrete.
  • the imprinting surface of the mats is the inverse of the pattern desired on the concrete surface. Mats are carefully laid out and substantially equal pressure is applied to each mat to leave an even pattern resembling a paved area on the surface of the concrete.
  • the desired appearance of a pattern imprinted concrete area is substantially the same as a paved area. Therefore, the same problems regarding creating an irregular pattern of paviours in paved areas also apply to pattern imprinted concrete areas .
  • One objective of this invention is to provide a paving slab which can be used to lay a paved area with an apparently irregular surface pattern.
  • a large area may be paved in a short time, and the complication involved in using individual paviours of different sizes is avoided.
  • a second objective of this invention is to provide a slab' that may be used to produce an apparently irregular pattern of paviours in a large paved area using only a few types, or even only one type, of paving slab.
  • Another objective of this invention is to provide a mould for the production of concrete slabs, and a method for making such a mould.
  • a further objective is to provide a textured mat which can be used to imprint an irregular pattern of paviours in a pattern imprinted concrete area.
  • a yet further objective of this invention is to provide a textured mat that may be used to imprint an apparently irregular pattern of paviours in a large concrete area using only a few types, or even one type, of textured mat.

  • the paving slab has a square central region and each of the lateral extensions is a square.
  • the paving slab has a number of pointing gaps formed in its upper surface to define an irregular pattern of paviours .
  • Each paviour is preferably rectangular in shape, and the paviours are preferably of different sizes and/or aspect ratios.
  • the paving slab has a rectangular central region, and is bounded on its longer sides by rectangular extensions of the same dimensions as the central region, and on its shorter sides by square extensions .
  • the central region may have an aspect ratio (the ratio of the length to the width of the central region) of from 0.5:1 to 2:1.
  • the square extensions may have sides equal in length to the shorter sides of the rectangular central region.
  • the paving slab has a rectangular central region, and is bounded on its longer sides by rectangular extensions of the same dimensions as the central region, and on its shorter sides by rectangular (i.e. non-square) extensions.
  • the upper surface of the paving slab is preferably formed with a pattern of paviours separated by pointing gaps .
  • a pointing gap may extend along the entire length of one or both of the longer sides of the central rectangular region if a "random coursed" pattern of paviors is desired.

However, due to the irregularity in the pattern of paviours across the entirety of the upper surface of the slab 18, the slab 18 has four different rotational orientations.

  • the respective slabs are laid such that a short edge FB of a first slab 23 opposes substantially half of the long edge KL of a second slab 31, and a second short edge BG of the first slab 23 opposes a short edge DK of the second slab 31.
  • pattern repetition may be avoided, or at least reduced, by laying the slabs in a different rotational orientation from each other.
  • Adjacent slabs may be positioned to ensure that a pointing gap 34 of a first slab 23 and a pointing gap 35 of an adjacent slab 33 are not aligned. If pointing gaps 34 and 35 are aligned an apparently continuous longer pointing gap is formed.
  • Adjacent slabs may also be positioned to ensure that a pointing gap 36 running the entire length of a notional boundary AB of a first slab 23 and the respective pointing gap 37 running the entire length of a notional boundary AB of an adjacent slab 32 are not aligned.

Internal walls within the mould, where the resin has penetrated between the paviour cores, are trimmed so that they extend inwardly from the mould cavity surface by approximately 10 mm, in order to form the pointing gaps in a cruciform slab moulded in the mould cavity. Spacing nibs on the sides of the paviour cores form recesses in the side walls of the mould which will then form spacing nibs on the side surfaces of the moulded slab.
  • the mould is supported with its cavity which has a cruciform base and generally vertical sidewalls open upwardly, and after a coating of release agent, preferably vegetable oil-based, has been applied to the mould, concrete is poured in to the mould to fill it .
  • release agent preferably vegetable oil-based
  • the walls extending up from the base of the cavity form pointing gaps in the cruciform face the concrete slab, and the recesses spaced around the sidewalls of the cavity form spacing nibs on the side edges of the concrete slab.
  • pigment may be applied to one or more area delineated by the walls on the base before pouring the concrete, to provide a slab having paviours of different tone or colour.
  • the slab is removed from the mould, and the moulding process optionally repeated to produce further slabs.
  • the mould may be used to manufacture slabs substantially the same as any one of the respective slabs shown in Figures 3 to 7 or 13.
  • Other patterns of paviours may be produced, by arranging paviour cores in different arrangements during the mould- making process.
  • the cores are arranged such that the cruciform slab has at least one paviour extending across at least one of the respective notional boundaries between the central square or rectangular region and the respective lateral extensions .

Abstract

L'invention porte sur une dalle de pavage en béton moulé ayant une face cruciforme et comprenant région centrale (ABCD) et quatre extensions latérales rectangulaires (LAKD, EFAB, BGCH, DCIJ) dont chacune est limitée sur un côté par un côté correspondant de la région carrée centrale, et un motif de pavage (5, 6) délimité sur la face, au moins l'un desdits pavés s'étendant à travers au moins l'une des limites de la région centrale. La région centrale peut être carrée ou bien rectangulaire. Le motif de pavage est irrégulier. Dans un mode de réalisation, chaque extension latérale s'étend sur la longueur entière d'un côté correspondant de la région centrale de la face cruciforme. Chaque extension latérale peut être sensiblement de la même dimension et de la même forme que la région centrale. En variante, chaque extension latérale peut s'étendre sur sensiblement la moitié de la longueur d'un côté correspondant de la région carrée centrale de la face cruciforme. Le motif de pavage peut s'étendre vers les bords de la face cruciforme, les pavés étant séparés par des jours (4) formés par des canaux, et la dalle peut en outre présenter des pions d'espacement (9) sur ses bords respectifs, les pions étant d'une épaisseur sensiblement identique à la largeur desdits jours (4).
