Definitions

  • the present invention relates to building materials such as coated products, e.g. masonry products, and particularly though not exclusively to coated masonry products possessing a coating to produce the visual and/or tactile effect of masonry, stone, brick or other building material or masonry material.
  • Masonry-effect products typically comprise a body part coated with a masonry-effect material designed to present the visual appearance of genuine masonry, such as stone or the like. Examples include cladding applied to the external surfaces of houses or other buildings, and the replacement of degraded masonry within a surface of a stone building as part of a renovation work. Such products are desirable when the use of corresponding genuine masonry on the building is not possible or is undesirable. This may be so if the cost of genuine masonry is prohibitive or if the cost or difficulty of applying it to a building (e.g. as cladding) is prohibitive.
  • Existing masonry-effect products may be manufactured by providing a body part of suitably strong yet light material (e.g. plastic) having the desired external shape and profile, then manually applying to a surface of the body part a coating of masonry-effect paint, emulsion or fluid mixture which, when hardened, aims to present the appearance of stone or the like.
  • Other methods of manufacture include moulding the masonry-effect coating material around a surface of the body part using a suitably shaped mould.
  • the present invention aims to provide means and methods which may be employed to address these issues.
  • the invention is to apply a desired external surface profile to a coated product (e.g. masonry-effect) by the scraping action of a correspondingly profiled scraping edge applied to the coating material when fluid.
  • the scraping edge may scrape away excess of the masonry-effect coating thereby to impose the desired profile shape upon the underlying coating revealed by action of the scraping.
  • This permits efficient manufacture and the scraping action has been found, surprisingly, to result in a rough surface texture to the coating material (when hardened) which much better replicated a stone masonry surface both visually and in tactile terms.
  • the invention may provide apparatus for manufacturing a coated product (e.g. masonry product) comprising a body part coated with a coating material (e.g.
  • the apparatus comprising: coating means or apparatus adapted to apply the (e.g. masonry-effect) coating material as a fluid to a surface of the body part; scraper or apparatus defining a scraping edge with a re-entrant profile to engage the coating material to scrape therefrom excess quantities thereof when fluid; drive means or apparatus adapted to impart relative motion between the body part and the scraper apparatus when engaged with the coating material thereby to impose the profile of the scraping edge upon scraped coating material remaining on the body part long the direction of said relative motion.
  • coating means or apparatus adapted to apply the (e.g. masonry-effect) coating material as a fluid to a surface of the body part
  • scraper or apparatus defining a scraping edge with a re-entrant profile to engage the coating material to scrape therefrom excess quantities thereof when fluid

  • the applicator apparatus may comprise an inlet opening in a side of the conduit for receiving said body part into the bore of the conduit.
  • the applicator apparatus may comprise an outlet opening in an opposing side of the conduit having a periphery defining the scraping edge.
  • the outlet opening may be arranged for receiving the body part from the inlet opening according to the imparted relative motion together with the coating material applied thereto within the conduit.
  • the conduit may be a hopper having an open top for receiving coating material in fluid form.
  • the hopper may have a front wall defining the inlet opening and a back wall opposing the front wall, and defining the outlet opening.
  • the side walls of the hopper may be slanted to converge towards the inlet/outlet openings.
  • the applicator apparatus may terminate at a closed terminus defined by a (e.g. flat) terminal surface at the terminal end of the conduit (e.g. the floor of the hopper).
  • the terminal surface may define a periphery or boundary (e.g. the floor) of both the inlet opening and outlet opening in common.
  • the terminal surface may extend from the inlet opening to the outlet opening. It may be adapted to provide a sliding support surface across which the body part may slide during its transit through the bore of the conduit from the inlet opening to the outlet opening.
  • surfaces of the body part other than that against the terminal surface are exposed to fluid coating material within the conduit and exit the outlet opening coated therewith.
  • the surface of the body part shielded from coating material by the terminal surface may remain substantially un-coated.
  • the uncoated surface(s) may be desirable for the purposes of attaching the coated product to a surface in use which may preferably be better left uncoated.
  • the body part may comprise a thermally insulating material which should preferably interface directly with the surface to which the product is to be attached (e.g. a house wall, or structure) which can remain thermally decoupled from the coating surrounding other surfaces of the product.
  • the outlet opening is preferably in register with the inlet opening across the bore of the conduit.
  • the imparted relative motion is substantially linear motion.
  • the inlet opening may be smaller than the outlet opening. Consequently, a given portion of the body part which according to said relative motion is opposed initially by a peripheral edge of the inlet opening and subsequently by the scraping edge of the outlet opening, may be spaced further from the scraping edge when opposed thereby.
  • the profile of a peripheral edge of the inlet opening may substantially match the profile of the scraping edge at a reduced scale.

  • the further scraping edge is aligned in register with the first scraping edge for receiving the coated and scraped body part output from the outlet opening for further scraping as described above.
  • the freshly scraped coating material upon a surface of a coated body part exiting the outlet opening of the coating apparatus often has a tendency to rise slightly as it is relieved of the over-pressure of the overlying coating material within the coating apparatus.
  • This that the thickness of the coating initially achieved by the initial scraping action at the outlet opening may not be the final coating thickness of the coating when hardened.
  • a second scraping action may be applied to the scraped coating on the body part after the scraped coating has had sufficient time to expand to its maximum extent.

  • the result is to thereby impose the profile of the scraping edge upon scraped masonry-effect coating (101 ) remaining on the body part long the direction of the relative motion of the body part past the scraping edge (see Figure 3).

  • the surfaces of the profile of the block intended to be coated are accessible and outwardly presented.
  • One surface of the block which it is not intended to coat is the surface upon which the block rests. This uncoated surface will present, when the coating of the block is otherwise complete, an exposed and accessible polystyrene surface with which to form an interface with elements of the external building surface to which the coated block is to be applied in use.

  • the shaping of the profile (16C) of the exit through-opening matches the shaping of the profile of the entry through-opening (16A) but on a slightly larger scale. This means that while the edges of the through-opening (16A) in the entry wall of the hopper are intimately close to opposing surface parts of the profiled polystyrene block (9) when received therein, the edges of the exit through-opening (16C) are more spaced from the same profile block surfaces (by about 5mm) when the profiled block is received within the exit through-opening.

  • the fluid coating material (100) may then be placed into the hopper to fully immerse the parts of the profiled polystyrene block located within the hopper between the entry and exit through-openings.
  • a subsequent linear movement of the profiled block in a direction along its longitudinal axis as indicated by the bold arrows in Figures 2 and 3, may then be applied to push the profiled block in a direction further out from the exit through-opening (16B) of the hopper.
  • This relative motion is preferably continued at a steady and uniform rate until the desired length of the elongate polystyrene block has passed through the exit through-opening of the hopper and has been coated by the coating material (100) within the hopper to provide a substantially uniform coating (101 ) over the surfaces of the elongate block which were exposed to the coating material within the hopper.
  • a further scraping edge (31 ) is provided by a plate (30) possessing a profiled through-opening substantially identical to the profiled exit through-opening (16C) of the exit wall (4) of the hopper.
  • the plate may be substantially the same as the exit wall (4) of the hopper.

  • the floor surface is in the form of a table or bench surface mounted upon legs to a convenient height.
  • An elongate rectangular through-opening (24) Figure 1 C is formed in the table surface and extends along a direction parallel to the intended movement of the polystyrene block and in register with both the entry and exit through-openings of the hopper.
  • a toothed belt-drive assembly (17) is mounted underneath the table surface, fixed to the table by suitable beams and struts, such that the toothed belt (18) of the belt-drive is, in part, presented through the through-opening (24) within the table surface.
  • the belt-drive comprises a three-phase electrical motor (20) adapted to power a drive wheel (21 ), and two separate belt wheels (22,23) around and upon which the toothed belt (18) of the belt-drive is mounted.
  • the motor (20) of the belt-drive (21 ) is adapted to drive the belt to travel around and over the two belt wheels (22,23) and the engaging drive wheel of the drive motor concurrently so as to move those parts of the belt exposed through the through-opening (24) of the table in a direction towards the hopper.
  • the speed at which the belt is so movable may be controlled by control of the speed of the drive motor (20).
  • Drive motor control apparatus such as would be readily apparent to the skilled person may be employed to this end.
  • the two separate belt wheels comprise a rear belt wheel (23) located adjacent to the rearmost end of the elongate through-opening (24) in the table top of the apparatus, and a fore-wheel located adjacent to the opposite end of the elongate through-opening nearest to the hopper.
  • the positioning of the two belt wheels (22,23) is such as to cause the teeth of those parts of the toothed belt (18) passing between the two belt wheels, to project beyond the upper periphery of the through-opening (24) at the surface level of the table of the apparatus so as to be able to engage with the opposing surface of the polystyrene block (19) presented to those teeth when the apparatus is in use and the polystyrene block lays over the through-opening.
  • the teeth of the toothed drive belt each comprise a blade which is elongate in a direction transverse to the length of the belt (and the through-opening in the table surface) so as to provide an extended blade edge with which to engage the underside of the polystyrene profiled block (9) as desired.
  • Each blade is shaped to taper to an apex in its mid region, thereby defining a substantially pointed blade which, preferably, has a rounded apex and otherwise straight blade edges either side of the apex.
  • the separation between successive blade edges is about 1 cm, or thereabouts.
  • Successive teeth are preferably arrayed in a regular array with a regular such spacing between them.
  • each blade is preferably between 2mm and 4mm, most preferably about 3mm in thickness (thickness prior to the thinner blade edge at the top of the blade element). This thickness has been found to provide the requisite tooth strength when employed as follows.
  • Operation of the belt drive to turn the toothed belt in the direction indicated by the bold arrows in Figure 1 B causes the array of teeth upon the belt to move towards the hopper and to push the polystyrene block in the same direction by action of the belt teeth engaging (i.e. "biting") the exposed polystyrene underside of the polystyrene block.
  • a pair of adjustable guide roller units (15) are suspended above the table surface of the apparatus in line with and over the through-opening (24) formed in the table surface.
  • Each roller guide unit comprises a plurality of rollers (15) adapted to touch the uppermost surface of the polystyrene block when located underneath them, so as to restrain any vertical movement of the polystyrene block such as might otherwise be produced by an upward pushing thereupon from the teeth of the toothed belt drive (18) underneath the polystyrene block.
  • each of the roller units (15) provide a back-stop to generate a reactive force against the polystyrene block when pushed from the opposite side by teeth of the belt drive wishing to engage the underside of the polystyrene block. This assists in the teeth engaging with that underside surface.
  • the vertical position of each of the roller units (15) may be adjusted to accommodate polystyrene blocks of different thicknesses and profiles by using dedicated height-adjusters (13, 14) via which the roller units are suspended over the table top surface.
  • Each guide roller unit is suspended from a transverse suspension frame mounted to and passing over the table surface in a direction transverse to the longitudinal axis of the through-opening (24) formed in the table surface.
  • a given roller unit (15) is suspended from a suspension frame via height adjusters (13,14) thereof.
  • a height adjuster preferably comprises a threaded screw element (14) mounted upon the suspension frame which concurrently engages a reciprocally threaded element (13) mounted upon the respective roller unit (15). Consequently, the turning of the screw element causes the reciprocally threaded element (13) and roller unit (15) to move axially along the threaded element (14).
  • the threaded element depends vertically from a transverse suspension frame.
  • a pair of opposed parallel guide walls (10) flank either side of the elongate through-opening (24) in order to restrain lateral movement of the polystyrene block (19) as it is driven therealong towards the hopper by action of the turning of the toothed belt drive (18) underneath it.
  • An adjustable guide platform (23A) is located between the rear belt wheel (23) and the fore belt wheel (22) of the belt drive in line therewith and is adapted to engage the (toothless) underside of the toothed belt (18) so as to support and maintain the vertical position of the toothed belt engaged with it.
  • the guide platform is adapted such that the belt is able to slide over the uppermost surface of the guide platform without being impeded.
  • the position of the guide platform is adjustable relative to the table surface (8) so as to adjust its spacing from the through-opening (24) formed in the table top of the apparatus. In this way, the guide platform may be used to adjust the extent to which teeth (19) of the tooth belt drive project or extend beyond the uppermost surface of the table through its through-opening in use.
  • the guide platform (23A) is also adjustable in inclination such that the inclination of those parts of the belt (18) passing over it may also be adjusted. It has been found that a slight inclination which causes the toothed belt to fall slightly in a direction away towards the hopper assists in providing a desirable degree of engagement between the teeth of the belt and the exposed polystyrene underside of the polystyrene block. It also enables a disengagement of teeth from the polystyrene of the block which causes far less damage to the polystyrene than at other inclinations.
  • Figure 4 shows a view of the apparatus illustrated in Figures 1 A to 1 D in which additional table units (25,26) are arranged either side of the hopper in order to support polystyrene blocks which are of considerable elongate length.

  • the coated product comprises the polystyrene block (9) illustrated in Figures 1A, 2 and 3.
  • a first coating comprises a base coating formed from a composition including a natural hydraulic lime, such as Prependuit (100A) into which is embedded a flexible glass-fibre mesh (102).
  • a second coating, applied over the first coating comprises Thermocromex (100B).
  • the thickness of the first coating is substantially 5mm and so is the thickness of the second coating.
  • the second coating is applied after the first coating has hardened.
  • Different scraping profiles are employed when applying the second coating as compared to the first coating. The profiles in question are of the same re-entrant shape, whereas the scale of the second scraping profile is slightly larger than that of the first scraping profile so as to permit the second coating material to be applied.
  • the speed of motion of the profiled block (9) relative to the hopper containing the material for coating the block is related to the circumference of the profile being coated.
  • a "coated profile parameter" may be defined as the value of the length of that portion of the circumference of the profile, viewed in cross-section across the longitudinal axis of the profiled block to be coated, excluding those portions of the circumference which are not intended to be coated.
  • the greater the value of the coated profile parameter the slower should be the relative motion of the profiled block as it is moved through the hopper.
  • the greater the viscosity of the coating material then the lower should be the rate of motion of the profiled block through the hopper.
  • Figure 6 schematically illustrates the method of calculating the coated profile parameter with reference to the cross-sectional profile (103 to 108) of the profiled block (9).
  • the circumference of the profile in question comprises contiguous lengths 103, 104, 105, 106, 107 and 108 of portions of the profile which collectively define the entire circumference of the profile.
  • all but the back profile portion (103) of the profiled block are intended to be coated. That is to say, the portions of the profile comprising the top (104), shoulder (105, 106), side (107) and base (108) of the profiled block are intended to be coated in this illustrative example with the result that the coated profile parameter would be calculated as the sum of the lengths of those profile portions.
  • the length of the top profiled portion (104) is 50mm.
  • the depth of the step (105) portion of the profile is 15mm.
  • the subsequent sloping shoulder (106) of the profile has a length of 131 mm which leads to a side profile portion (107) having a length of 85mm.
  • the base portion of the profile (108) has a length of 175mm. The sum of these lengths defines the value of the coated profile parameter, which is 456mm.
  • a profile having this profile parameter should preferably be coated with a Prependuit composition at a rate of motion corresponding to 30 seconds per metre of uniform linear motion of the profile through the hopper. Furthermore, experiments have shown that a profile having this coated profile parameter when coated with a Thermocromex composition should be subject to a relative movement corresponding to 95 seconds per metre of uniform linear movement of the profile through the hopper. It is to be noted that profiles of a widely varying variety of shapes may each result in the same or similar coated profile parameter (e.g. within a range) to which the same relative motions should be applied, for a given coating material, for optimal results. Furthermore, if different (e.g. fewer, more or other) profile portions of the profile (9) illustrated in Figure 6 are intended to be coated, this may also result in a different coated profile parameter and, therefore, a different optimal relative motion to be imposed during the coating process, depending on the coating material in question.
