Definitions

  • the following invention relates to a method and apparatus for forming a building panel.
  • the invention also relates to a building panel.
  • Lightweight concrete building panels are known. Such panels are produced in a raw, unfinished condition for installation. After being installed into a building under construction, the panels are rendered or otherwise coated to provide an acceptable surface finish. This process requires the labour of a skilled renderer in applying the rendered finish with a trowel Furthermore, the strength of such known lightweight concrete panels is not high.
  • This apparatus comprises two horizontal mould sections and means for moving the two mould sections together to form a mould cavity.
  • a flowable settable material is laid onto a surface of each mould section and partially set.
  • the mould sections are then brought together and further flowable material is introduced between the first layers of flowable material
  • the sheet material is formed once all the flowable material has fully set.
  • mould sections or baffles horizontally requires a significant amount of area, and thus limits the number of panels producible at any one time
  • re-orientating the mould sections or baffles produces difficulties concerning mould section or baffle construction as well as reliable pre-coating of the mould section or baffle.
  • a method of forming a building panel or panels comprising the steps of:-
  • the baffles can be moved together after filling the space with core material but prior to setting of the core material and coating material.
  • the baffles are moved apart and/or separately removed after setting ofthe core material and coating material so as to release the formed panel(s).
  • the method further provides n+1 baffles in a parallel spaced interrelationship, between which n panels are formed where n equals any integer greater than or equal to 1.
  • the panels are removed in a direction substantially parallel to the plane of the baffles by application of force thereto.
  • the baffles are located within a mould box or supporting frame.
  • the baffles are moved toward one another by means of hydraulic clamping cylinders.
  • an apparatus to form a building panel or panels between baffles including:
  • each baffle is substantially hollow, having a pair of spaced apart side sheets.
  • each baffle has air inlet means by which air can be injected to the space between the sheets so as to outwardly expand the same under pressure to assist in releasing the set panels from the baffles.
  • each baffle is solid.
  • Plywood is a suitable material for a solid baffle.
  • the plywood can be plastics coated.
  • the baffles can be a composite of plywood, nylon, PVC and steel.
  • the baffles have extraction engagement holes to which an extraction device can be anchored for the purpose of applying force to the set panels for removal.
  • the supporting frame is formed upon a mobile structure.
  • the mobile structure has one or more posts to which clamping cylinders are affixed, said clamping cylinders being associated with side walls of the supporting frame.
  • the side walls of the supporting frame act as end baffles.
  • the means for substantially filling the space between the two baffles with a settable core material includes a hopper from which there extends one or more filling tubes, the hopper being mounted upon a frame and being pivotable about a horizontal axis, the hopper being adapted to be raised and lowered such that the filling tubes enter and are withdrawn from a space between adjacent baffles while core material is being delivered thereto by said filling tubes.
  • means are provided to oscillate the hopper horizontally, during vertical withdrawal of the tubes and delivery of the core material.
  • cleaning means are located along said path and operable to clean said baffles as said baffles pass through said cleaning means.
  • a mould box or supporting frame 10 has a pair of side walls 11, a bottom 12 and a pair of solid end doors 13. Walls 11, bottom 12 and end doors 13 define a cavity into which a number of baffles 14 can be inserted.
  • the sides 11, bottom 12 and end doors 13 are preferably fabricated from solid steel or other metal or strong material.
  • the end doors 13 are hinged at the bottom edge thereof to the bottom 12.
  • the doors open outwardly and downwardly as shown in Fig. 1.
  • the baffles 14 fit neatly into the mould box or supporting frame 10 and divide the mould cavity into sections, i.e., individual cavities between respective baffles into which building panels are cast.
  • the internal length of the mould box or supporting frame determines the panel length which is typically 2.6m.
  • the internal height of the mould box or supporting frame determines the panel width which is typically 0.6m.
  • the spacing between the inserted baffles is set by means of spacers 22 which are typically 75mm wide. That is, the space between the baffles is typically 75mm. It should be appreciated however that these dimensions can vary depending on the required panel dimensions.
  • the mould box or supporting frame is situated upon a mobile base 20 has wheels 23.
  • a pair of posts 19 extends upwardly from the mobile base 20.
  • Clamping cylinder 18 cooperates with one of the side walls 11 as shown in Fig. 5.
  • the opposing side wall 11 is affixed to the base 20.
  • a lifting frame 15 as shown in Fig. 2 has a pair of hooks 21 at its lower extremities. These hooks 21 are adapted to cooperate with individual baffles 14 for the purpose of lifting the same out of the mould box or supporting frame.
  • the lifting frame 15 can be raised and lowered by means of an overhead pulley system or crane for example.
  • each baffle 14 has a pair of spaced apart sheets 24 defining a space 25 therebetween.
  • Sheets 24 are preferably steel or other metal such as aluminium.
  • the sheets are intended to be substantially planar, though capable of flexing under the application of internal air pressure to the cavity 25.
  • Each baffle 14 has an extraction engagement hole 16, the purpose of which shall be described below.
  • building panels can be fabricated as follows.
  • the lifting frame 15 can be raised so as to raise an individual baffle 14 from the mould box or supporting frame 10.
  • the baffle 14 can then have applied thereto a coating.
  • the coating as applied to the surfaces of the baffles 14 is typically 3mm thick. However, this dimension can vary depending on particular applications.
  • the coating is applied by a spraying technique, typically using apparatus of a type, though smaller than, spray guns used for concrete pool finishing and in the mining industry and sold under the trade mark "Shot-crete".
  • the coating material typically has a blend of sand, cement, water and a cross-linking polymer emulsion.
  • the coating material can also include supplementary cementitious materials.
  • the cross-linking polymer emulsion is sourced from National Starch and Chemicals Pty Ltd. However, there are many other polymers available and suitable for use in the present process.
  • the emulsion is typically used as a concrete additive for repair and patching of concrete.
  • the emulsion is used as a partial replacement for water to give flexibility and added tensile strength to the coating applied to the opposed planar surfaces of the baffles 14.
  • the cross linking polymer emulsion is used as a partial replacement for water to give flexibility and added tensile strength to the spray mortar skin.
  • Optional additives to the coating material include fibres, typically polypropylene fibres as used in concrete crack control, coloured oxides, silica fume and flyash. The coating material can be modified to suit any local materials or finished panel requirements.
  • the coating material in general should display good adhesion to the core material, good tensile strength, flexibility, water resistance and provide a durable surface to the finished panel.
  • the baffle 14 With the end doors 13 in the closed position, the baffle 14 is inserted into the mould box or supporting frame 10.
  • the baffles can be placed first, then the doors closed to assist in aligning the baffles into precise position.
  • lifting rods are also inserted into the end doors for the purpose of assisting with removal of the panels after hardening.
  • the spacers 22 are then positioned alongside the baffle. The coating and inserting steps are repeated for the desired number of baffles.
  • the clamping cylinders 18 are then activated to force one of the side walls 11 toward the other until such time as the spaces between the respective baffles is limited by their engagement with the respective spacers 22.
  • the core mix Whilst the sprayed coating is still fresh, the core mix is added to the cavities between the baffles.
  • the mixture used for the core material typically has sand, cement, water, an air entraining agent and a lightweight aggregate, typically coated polystyrene beads, possibly of the type known as BST.
  • the core material can also contain supplementary cementitious materials and/or chemical admixtures.
  • the air entraining agent can be a commercially available admixture.
  • the BST material has expanded polystyrene, chemically coated beads.
  • the wall panels Whilst maintained in position, the wall panels are allowed to cure, typically over an 18 hour period.
  • the coating material thus fuses with the core material to provide a strong integral wall panel.
  • the clamping cylinders 18 are released so as to remove lateral pressure from the walls 11 and baffles 14.
  • air can be applied under pressure to the space 26 between the respective opposed sheets 24 of the baffles 14. As a result the sheets 24 will flex outwardly, detaching the panels 17 therefrom.
  • a hand held pneumatic cylinder has a pair of hooks is then used to push the individual panels 14 out of the mould box or supporting frame. To this end, the hooks on the pneumatic cylinder can be engaged with the extraction engagement holes 16 at the ends of each baffle 14.
  • a pushing element or foot of the cylinder is then engaged with the end surface of the panel 17 to push the same out through the opposed opened door region of the mould box or supporting frame. That is, the reaction force associated with this pushing action is transferred to the baffles 14 by interengagement of the hand held tool with the baffles 14.
  • the extraction cylinder is held like a rifle by an operator. With both doors 13 open, and upon activation of a trigger, the pushing foot pushes the concrete panel out through one of the open doors 13 to be received by a pallet for dispatch.
  • the baffles 14 might have an internal frame structure to prevent the opposed sheets 24 from closing towards one another during the application of force by clamping cylinders 18.
  • the extraction engagement hole 16 might also serve as a means of applying the required internal pressure to the baffle cavity 25 to release the formed panels 17.
  • the extraction cylinder might have two triggers or a two-pull trigger action, one activation of the trigger, or one of the triggers, serving to activate engagement hooks, and the other acting to activate the pushing foot to extract the formed panel.
  • the pushing foot pushes the formed panels through a distance of about 300mm for the purpose of allowing access for manual lifting to the pallet.
  • steel or other reinforcing mesh or other reinforcing means can be positioned between the baffles to be surrounded by the core material.
  • a further feature can be the fitting of a profiler which can trim the edge of the panel as cast and provide a detail such as a tongue and groove to the edge.
  • FIGs. 7 to 13 of the accompanying drawings there is schematically depicted the plant layout and other detail associated with a modified method and apparatus for forming building panels.
  • Figs. 11A, 12B, 13A and 13B show further modified apparatus.
  • This plant layout is designed for higher production throughput than is the case as discussed above with reference to Figs. 1 to 6A.
  • the overall method is similar to that described above with reference to Figs. 1 to 6A.
  • the baffles no longer include a pair of spaced metal sheets, but instead are formed as a single sheet of material or laminated solid layers of material. Typically, a single sheet of plastics coated plywood forms each baffle 14.
  • the plant layout of Figs. 7 and 8 can be described as follows. The individual baffles are placed in a mould box or supporting frame 70 and carried by a fork lift to a chain drive conveyor 71. The individual baffles are then picked up by a baffle unloading hoist 72 and conveyed in the direction indicated by arrow A along a suspended pipe conveyor 73.
  • the pipe conveyor conveys individual baffles to a cleaning and oiling station 74 where the baffles are cleaned and coated with oil which acts as a mould release agent.
  • the individual baffles are then conveyed to spraying station 75 where the individual baffles are coated on both sides with a coating material.
  • the panels are then conveyed by the pipe conveyor to the core filling station 76.
  • the empty mould box or supporting frame 70 is conveyed by a chain drive or other conveyor apparatus to a rotation station 77 where the mould box or supporting frame 70 is rotated through 180° and then further conveyed by the conveyor belt or chain drive conveyor the core filling station 76.

  • the baffles 14 are suspended from a monorail 73 that is used to transport the individual baffles through the process stations 400, 75 and 410. Individual baffles are cleaned, oiled and generally prepared such that they can receive the settable coating material and can be separated from the moulded panel after it has cured.
  • Demoulding and mould disassembly which occurs at station 420 takes place as follows. Once the panels are sufficiently cured and hardened, the still full moulds are disassembled to remove the panels. The baffles and panels are progressively stripped from the mould frame. The device and operators first take off the outermost baffle and replace it on the monorail as at the beginning of the process. The device and operators then separate the outermost panel from the mould frame and deliver it to the edge detailing and palletising station (Fig. 14 and Fig. 14A). The process is repeated until all of the full mould has been disassembled and the formed panels removed and delivered to the detailing station.
  • the edge detailing and palletising station is shown in Figs. 14 and 14A.
  • the formed panels are delivered to the edge detailing and palletising station to be completed.
  • the edge detailing station uses a grinding wheel to create a groove 500 in one long edge of the panel to match the tongue 510 that is formed in the opposite long edge of the panel during the casting process.
  • the panels are indicated by reference 520 in Fig. 14 and Fig. 14A.
  • the finished panels have a surface finish thereon determined by the surface texture of the baffles.
  • the settable core material melds to some degree with the skin material and provides a hard wearing and durable surface in the finished panel which does not require subsequent rendering or in situ cosmetic treatment.
  • FIG. 10A there is schematically depicted an individual baffle 100 which includes a plywood panel 105 surrounded by a steel frame 101. At the upper part of the steel frame 101, there extends a pair of projections 102 which are engaged by hooks suspended from the pipe conveyor. At the bottom of each baffle 100 there projects a pair of mould box or supporting frame alignment lugs 104 which serve to engage with a locating track 135 in the bottom of the mould box or supporting frame, which locating track includes recesses 136 which are spaced by a set distance defining the thickness of a panel to be moulded between the baffles.
  • Fig. 11 there is shown the detail of a method of simultaneously spraying both sides of a solid baffle 14.
  • the spray assembly includes a plurality of spray guns 110 positioned at both sides of the baffle 14.
  • the baffle 14 is drawn by the pipe conveyor 73 inbetween the spray guns 110 during spraying so as to achieve a uniform coating on each side.
  • a carriage 112 is associated with the pipe conveyor 73 in somewhat the same manner as a curtain ring is associated with a curtain rod.
  • the carriage is pulled along the pipe conveyor by a cable or chain.
  • a cable 113 suspended from the carriage 112 includes hooks 103 (Fig. 10A) which engage with the projections 102 of each baffle to suspend and convey the baffle 14.

  • the means for providing the oscillation in the direction of arrow B can be camshafts, solenoids, pneumatic rams, hydraulic rams or other oscillation mechanisms.
  • the aim is to fill the space between the baffles with core material at a controlled rate. That is, the rate of delivery of the core material is adjusted such that the core is filled at the same rate as the rate at which the nozzles are vertically withdrawn from the mould box or supporting frame. This controlled rate of filling prevents the core material from shearing a coating material from the baffle surfaces during the filling process.

  • baffles of the process of Figs. 7 to 13 to that of Figs. 1 to 6A it is no longer necessary to apply air to release panels from the baffles. This is due to the fact that the baffles are solid. Also, there is no need to apply lateral force to each baffle to position the same as described with reference to Figs. 1 to 6.
  • a hand-held pneumatic cylinder is not used in the plant of Figs. 7 to 13 to remove the panels from the mould box or supporting frame. Rather, each baffle is sequentially moved sideways and lifted from the mould box or supporting frame using a lifting system as described earlier.
