Description
BUILDING PANEL AND METHOD OF MANUFACTURE Field of the Invention
The present invention relates to building panels, in particular their method of manufacture.
Background to the Invention
Insulated panels are well known in the construction industry. They can be made structural in order to take vertical loads, or can be provided in a relatively flexible form for insertion in wall, ceiling or roof cavities.
Examples of structural insulated panels (SIP’s) generally comprise a layer of insulation which is sandwiched between two layers of orientated strand wooden board (OSB). The panels are manufactured in any size to order. The wood is adhered to the insulation so that it doesn’t separate under vertical loading. The edges of the board are generally sealed using further pieces of wooden board. The edges may also be made with a projection in order that they may be overlapped against a neighbouring SIPs panel and movement inwards and outwards is prevented.
Other forms of insulated panel use plywood, plastic or composite in place of the OSB boarding. This has the advantage of being lighter, and because the composite or plastic is mouldable, then rapid machine construction is possible. In most cases the panels consist of two half shells of plastic surrounding a foam core. The plastic is adhered to the foam core. However there are a number of problems associated with these panels and the methods used to manufacture them.
The plastic or composite used in these sorts of panels requires moulding and because a relatively thin layer (1-3mm thick) is used compared to the OSB equivalent, they are not considered suitable for vertical structural loading. Also, in order to make the plastic fit around the foam, or incorporate a particular shape, it has to be moulded. The costs of making the moulds means that panels of only regular sizes can be manufactured and still make the process commercially viable. Furthermore, when pressure is applied to the two half shells in order to bind the adhesive on the inside between the plastic and the foam, it is common for the edges of the plastic or composite to separate from one another and from the foam around the edges of the foam.
There has now been devised a method of manufacturing building panels which overcomes and/or substantially mitigates the above referenced disadvantages associated with the prior art.
Summary of the Invention
In an aspect of the invention there is provided a method of manufacturing a building panel comprising the steps of: a) forming a board of insulative material, b) forming a first sheet, the first sheet comprising a first set of grooves scored in a first face, the first set of grooves defining fold lines in the first sheet, a second set of grooves scored in the first face, the second set of grooves defining outwardly projecting flanges of the first sheet, c) applying adhesive to the first face except the outwardly projecting flanges, d) laying the first sheet over the board, the first face being in contact with the board and positioned with the edges of the board corresponding with the first set of grooves in the first face, e) repeating steps b)-d) for a second sheet, f) folding the first and second sheets around the board and bonding the projecting flanges of the first and second sheets together, g) pressing the two sheets towards each other around the board; and h) removing the projecting flanges.
The method according to the invention is advantageous primarily in two ways. Firstly by introducing grooves into the sheets to define fold lines, means that the plastic does not have to be pre-moulded to the shape of the board and can be utilised flat. As long as the grooves fall in line with the edges of the board when the sheets are laid on to the board, the edges of the board will form a natural pivot point for the sheets to fold around. Thus the sheets form a tight fitting enclosure around the board without any pre moulding for shape. Secondly, the step of bonding the projecting flanges of the first and second sheets are together means that sheet material on the sides of panel does not separate from the board, when the two sheets are pressed together around the board.
The board according to the invention comprises two opposing faces and sides each having a surface area equal to or less than one of the faces. Thus the board may be cuboidal or have a square cross section, but generally will have a rectangular cross section. The faces may be square, rectangular, triangular or any quadrilateral shape.
In the method of the invention, the first sheet and the second sheet may be laid over the board simultaneously. This speeds up the manufacturing process.
Insulative according to the invention means acoustically insulative or thermally insulative. Therefore the insulative material may be any material which has these properties. Preferably, the insulative material is an expanded foam material. Examples of suitable materials include expanded foam polystyrene, Styrofoam, or Celotex®. Expanded foam materials, otherwise known as rigid foams, have high compressive strength and are able to support weight. As well as strength and durability, rigid foam insulation also provides additional properties such as fire resistance and acoustic insulation to minimise the level of sound travelling through the panel.
The grooves in the first sheet and the second sheet create natural fold lines for the sheets to bend round. The material of the sheets may be elastic in nature, and therefore resist bending. Even if this is the case when force is applied to the sheets to bend them around the edges of the board, the adhesive will then hold the sheets in place. It is recognised though, that by forming grooves on the sheets to create the fold lines, the elastic forces are reduced, and therefore the glue is less likely to fail. All this being said it is preferable that the first sheet and the second sheet are deformable. This has the benefit that when the sheets are bent around the edges of the board they remain substantially in place. It will be recognised that there may be some flexing of the sheets brought about by some elastic components, but in general the sheets will preferably hold their shape when bent.
The first sheet and/or the second sheet may be metal. This has the benefit that the panel can be manufactured to have structural qualities and resist forces applied to the faces or the sides, i.e forming a so called “structural panel”. Thus the panel may be classed as a structurally insulated panel (SIP), and can be used for structural bearing purposes rather than just for filling spaces.
When the first sheet or the second sheet is metal, preferably the metal is aluminium. This is because aluminium is easy to form into sheets, light, deformable, thin and strong, easy to score and does not rust.
The first sheet and/or the second sheet may a plastics material. Plastics materials provide the right deformability characteristics, are insulative in themselves, commercially viable and available, and lightweight. Other types of material may be used for the sheets, such as fibre board, composite, or cardboard.
Preferably the plastics material is PVC (polyvinylchloride). The PVC may be unplasticised. Other examples of suitable materials include nylon, rubber, polystyrene, polyethylene terephthalate, polyethylene, or polypropylene.
The grooves in the first sheet and the second sheet are preferably routed into the respective sheets. Both the first and second set of grooves define fold lines in the respective sheet, however necessarily the first set is inward from the second set which defines the projecting flanges of the first sheet. In this invention, inward from the first set means towards the centre of the face of the sheet. The first set of grooves defining fold lines in the first sheet are such that when overlaid the board correspond with the edges of the board. Thus the first set of grooves may be continuous around the face of the sheet. In order for the sheets to cover the sides of the board evenly when bent around the board, there may be necessarily gaps cut within the corners of the sheets so that when the sheets are bent over the edges the material at the corners contacts each other. Due to these gaps, the second set of grooves are therefore not continuous around the sheet, and extend only in the portions where the sheet would extend around the sides.
The first set of grooves and/or the second set of grooves may be in single lines scored into the respective sheets. Alternatively, the first set of grooves and/or the second set of grooves may be in multiple lines scored into the respective sheets. Preferably, the first set of grooves are scored as single lines and the second set of grooves are scored as double lines running parallel with one another. This provides greater flexibility to the second set of grooves than the first set, and means that the outwardly projecting flanges can be bent away from the first face more easily (ie projecting outwards from the panel).
The adhesive may be any adhesive suitable for bonding metal or plastics to insulative board. Preferably the adhesive is a contact adhesive. The adhesive may be sprayable. Examples of suitable adhesive are epoxy based and poly-chloroprene based. This provides the correct flowability. Furthermore, the time to cure can be altered so that it can either work instantaneously or with a delayed curing to allow for positional rearrangement of the sheets.
The outwardly projecting flanges project outwards from the side of the panel. The outwardly projecting flanges of the first sheet and the second sheet may be bonded together by riveting, welding, or clamping. Preferably the outwardly projecting flanges of the first sheet and the second sheet are bonded together by crimping. Non limiting examples of suitable welding include spot type welding, heat welding, or ultrasonic welding.
Preferably the second set of grooves define frangible portions for removal of the projecting flanges. In use, by twisting the flanges with respect to the panel, they will separate at the frangible portion from the remainder of the panel. This action of breaking off the flanges, leaves a clean side to the board. The parts of the sheet at the side of the panel still adhere to the board because by now the pressing step has caused good bonding of the adhesive applied to the inside of the sheets to the board. Once the flanges are removed there is no further manufacturing pressure applied, and so the sides of the panel remain clean and attached.
Preferably, the step of pressing the two sheets toward each other around the board is performed in a membrane press. This provides even pressure around the whole surface area of the panel. As the flanges are bonded together the sides of the panel do not bulge outwards during this process. A normal lateral press (ie applying force just to the faces of the panel). This has a similar effect to a membrane press but no force is applied to the sides.
The method according to the invention may further comprise the step of forming a plurality of openings in at least one side of a first panel and a plurality of tongues mutually engageable with the openings in at least one side of a second panel. The tongues and openings are designed so that neighbouring panels may be coupled together. Thus, there may be a plurality of building panels coupled by engaging the tongues of the second panel with the openings of the first panel. It will be appreciated that a plurality of panels could be coupled in the same manner and as part of the present invention if the first panel just had openings and a second and third panel on either side, just had tongues. And this pattern was repeated along the wall. This feature of the invention is advantageous because it allows the user to form a wall structure, rather than an infill structure for a ceiling or the like. The wall can be made to any dimensions, as panels can be added on laterally and longitudinally.

Detailed Description of the Illustrated Embodiment
An example of the method of manufacturing a building panel according to the invention is provided below. a) forming a board of insulative material,
In this step the board 30 is formed as shown in Figure 1. The board 30 is a styrofoam board, having a rectangular cross section. The board has opposing faces 32a, 32b, edges 34 (12 number in total), and sides 36 (4 number in total). The board 30 is manufactured using conventional techniques for forming Styrofoam. The foam board used in the present example is Styrofoam block foam LBH-X, manufactured by Dow chemicals, Ltd.. b) forming a first sheet, the first sheet comprising a first set of grooves in a first face, the first set of grooves defining fold lines in the first sheet, a second set of grooves in the first face, the second set of grooves defining outwardly projecting flanges of the first sheet,
In this step the first sheet 10 (see figure 1) is a generally planar sheet of PVCu approximately 1.5 mm thick. The sheet 10 is scored on its under surface (the face of the sheet facing the board) using a router to create a first set of grooves 12 and a second set of grooves 14. The first set of grooves 12 are positioned so that they align with the edges 34 of the board 30. The first set of grooves are the innermost set from the edges of the sheet. The face of the first sheet 10 is of greater surface area than the surface area of one face of the board. In this way the first sheet over hands the edges of the board. The overhanging portions 16 extend half the width of each side. In order that the overhanging portions 16 can extend completely and neatly around the side of the board there are gaps 17 cut into the sheet 10. In the example shown these are right angle gaps, so that when the overhanging portions 16 are folded around the edges 34, they meet up. At the outward edge of each overhanging portion 16 is an outwardly projecting flange 18, which is defined by the second set of grooves 14. In the example shown the flange 18 is bent at right angles to the overhanging portion, so that when the overhanging portion is in contact with the sides of the board, it projects out parallel with the face of the sheet and/or the board. c) applying adhesive to the first face except the outwardly projecting flanges,
In this step, a moisture cure contact adhesive is sprayed onto the first face (inside face) of the first sheet 10. All areas of the face of the first sheet 10 are covered except the flanges 18. The adhesive used is a high grade polychlo-roprene based sprayable adhesive which combines excellent resistance to creep at high temperatures with good flexibility at very low temperatures. d) laying the first sheet over the board, the first face being in contact with the board and positioned with the edges of the board corresponding with the first set of grooves in the first face,
In this step the first sheet 10 is laid over the board 30, adhesive side down (ie in contact with the board). The position of the sheet 10 is such that the edges of the board 34 mate with the first set of grooves e) repeating steps b)-d) for a second sheet,
In this step the steps b)-d) above are repeated for a second sheet 20 (see figure 1). The second sheet is substantially the same as described above for the first sheet. The second sheet 20 thus has a first set of grooves 22, a second set of grooves 24, overhanging portions 26, outwardly projecting flanges 28 and gaps 27. The grooves are applied as above using a router. Adhesive is also applied as described above. The sheet 20 is laid on the board 30 on the remaining half of the board not covered by the first sheet 10. As the dimensions of the second sheet are the same as the first sheet, the laying over of the two sheets results in the whole surface area of the board being covered. f) folding the first and second sheets around the board and bonding the projecting flanges of the first and second sheets together,
In this step, the two sheets 10, 20 are bent around the edges 34of the board. The first set of grooves 12, 22 in each sheet form natural pivot/fold lines. As the overhanging portions 16, 26come down onto the board 30 the gaps 17 close and because the dimensions of the second sheet are the same as the first sheet, the laying over of the two sheets results in the whole surface area of the board being covered. The adhesive on the inside of the two sheets begins to adhere the sheets to the board. The projecting flanges 18, 28 align parallel and overlapping with each other and are spot crimped together at intervals around the perimeter of the panel. The area of the crimp is indicated as 40 in figure 2 in both sides of the cross section. g) pressing the two sheets towards each other around the board;
In this step the whole panel is placed in a membrane press and a vacuum pressure applied across the whole surface area of the board. Because the flanges are bonded together, the overhanging portions of the sheets do no disassociate from the sides of the board. After the pressing process the panel has a cross section as shown in figure 2. h) removing the projecting flanges.
This is the final step in the method and involves twisting the projecting flanges back and forth until they break away from panel. The second set of grooves provide frangible fold lines in order to facilitate this process. After the flanges have been removed the panel is ready for use, and has a cross section as shown in figure 3.
In a further example of the method of the invention, the second sheet 20 is an aluminium sheet and the first sheet 10 a PVC sheet. A plurality of panels are coupled together to form a wall. The coupling is achieved by adding openings 60 into one side of each panel, and tongues 62 in the other opposing side of each panel. The tongues 62 and openings 60 are staggered slightly as in figure 4. The tongues 62 are designed to engage with the openings 60 in a sliding action. When engaged, further lateral and longitudinal movement is prevented. A wall is created by coupling consecutive panels together. The wall can be made to any dimensions by adding on panels laterally and/or longitudinally.
In a further example of the method of the invention, the second sheet is an aluminium sheet and the first sheet a PVC sheet, and a plurality of panels are coupled together to form a wall as substantially described above. The coupling is achieved by adding openings (as described above) into both sides of one set of panels, and tongues (as described above) into both sides of a second set of panels. The tongues are designed to engage with the openings in a sliding action. When engaged, further lateral and longitudinal movement is prevented. A wall is created by coupling panels from the first set with panels from the second set and so on.
