Preferred embodiments of the invention will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in which:
Shown in situ in
In the example shown, the connector 10 is received between an end face 5 of the edge 2 and the component 50; more particularly, it is received between the end face 5 of the panel 1, defined by the edge 5 thereof, and a like end face defined by the edge of the like panel, and secured against those faces to interconnect the panel 1 and component 50. The connector 10 comprises a strip section 11 defining a first face 12 which is arranged so as to be adjacent the end face 5, and a second face 13 which is opposite to the first face 12 and arranged so as to be adjacent the end face of the edge of the other panel 50. The faces 12 and 13 are secured, via the adhesive 20, to the end face 5 of the panel 1 and the end face 5 of the component 50 respectively.
In the present example, as well as each of the other examples, described and illustrated herein, the adhesive is a silyl-modified polyether (“MS polymer”) adhesive, which bonds reliably to the (indirectly) abutting end faces 5, each of those end faces comprising a surface of the substrate, which is relatively rough given the interstices distributed throughout the foam material, and end faces of the skins 4 to either side of that substrate. This adhesive, advantageously, also provides a seal between each connector face and the respective panel/substrate end face which it bonds together. In the present example, it is the surfaces defined by the substrate that are bonded to the connector 10 (though, as indicated above, the material from which the skins 4 are formed is of itself bondable by the adhesive). Other types of adhesive/sealant, such as (for example), silyl-modified polyurethanes (“SPUR polymers”), are possible without departure from the invention, as will be appreciated by a person skilled in the art.
The connector 10 is configured with an enlarged portion, defining an outer edge of the connector 10 and defining also opposed spacer portions 14, each of which (like the portion 11) extends the length of the connector (and indeed also the lengths of the edges 2) and is receivable directly against a lateral extremity of the respective end face 5 (in this particular case the outer lateral extremity), including the end face of the outer/exterior covering 4 thereof the panel 1 and panel 50. Owing to each spacer 14, the connector face adjacent to it (on the side of the connector on which that spacer is arranged) is spaced slightly from the end face 5 adjacent thereto, whereby to each side of the connector 10 there is defined a void 21, between the connector face at that side and the end face 5 adjacent to/facing it. Advantageously, there is thus an ensured evenness of spread of the adhesive between the first and second faces of the connector and the end faces to which they are bonded; in particular, adhesive is not forced out from between the connector and end faces (and thereby rendered useless) as it would tend to be in the absence of the spacers 14 (so that wastage of adhesive is reduced considerably). The protuberances 14 could, without departure from the invention, be intermittent along the length of the connector (e.g. be defined by discrete, spaced apart, projections each having, for example, the cross-sectional configuration as illustrated), though an advantage of their being continuous along that length is that the outer edge of the connector defines a trim, affording the outer edge of the joint a uniform, smooth appearance, contributing to aesthetics.
The outer edge of the connector 10 serves an important further role (which is enhanced by the spacers 14 at that edge being continuous), namely to engage (and more particularly to abut) an end face of a skin 4 of the panel 1 (the exterior skin 4 in this particular example) so as to transfer, to that skin, loading (including through the connector 10) exerted on the substrate 3 of the panel 1 by the panel 50, the skin 4/skin material, braced against distortion/buckling by the substrate 3, being stronger than the substrate 3/substrate material and thus, unlike to the substrate 3/substrate material, being apt to bear that loading—be it compressive, tensile or shear (translation or torsional) loading. The connector 10 also engages (and more particularly to abuts) an end face of a skin 4 of the like panel 50 (the exterior skin 4 in this particular example) so as to transfer, to that skin, loading (including through the connector 10) exerted on the substrate 3 of the panel 50 by the panel 1 (as a result of the latter panel supporting the former panel), the skin 4/skin material of the panel 50 likewise being braced against distortion/buckling by the substrate 3 of the panel 50.
The protuberances 14 additionally facilitate alignment of the connector faces with the respective end faces to which they are bonded.
The portion of the gap 22 between the panel end face 5 and the other component 50, which is not occupied by the connector 10, can, if appropriate, be supplied with a compound which expands to fill that portion of the gap, such as self-expanding foam, e.g. self-expanding polyurethane foam (PU), which the inventors have found, advantageously, bonds well to the faces defined by substrate 3, affording the connection additional strength and/or additional acoustic and/or thermal insulation and/or resistance to liquid/moisture ingress.
The connection between the panels 1, defined by the connector 10 and adhesive 20, is, advantageously, resistant to shear (translation or torsional) in a plane parallel to either of the bonded connector faces, tension in a direction perpendicular to those faces (which faces are parallel to/in alignment with the edge faces) and moment loads about the longitudinal (length) axis of the connector, including in particular loading that would tend to pry open the mitre joint about the outer edge thereof.
The connector 10, particularly advantageously, transfers to the covering 4 to which it extends and with which it is engaged, loads exerted on the substrate 3 of the panel 1 by the component 50, including loads transmitted through the connection/connector itself, which loads would otherwise be born by the substrate 3. In transferring loads to a lateral side of the panel, defined by the skin/covering 4, the connection/connector functions in the nature of a lintel.

In each of the assemblies shown in

The connector 10A is configured in the form of a parallel flange channel, comprising a web portion 11A, opposed portions of which define a first face 12A and second face 13A and a pair of parallel flange portions 15 each extending upwardly from a respective lateral end or edge of the web portion 11A.
The web portion 11A and flange portions 15 define an open-ended cavity into which the panel edge 2 is closely received, whereby one of the flanges 15 extends parallel and adjacent to the outer surface of one of the coverings 4, and the other flange 15 extends parallel and adjacent to the outer face of the other covering 4. Each flange is configured, at a distal end thereof, with a respective protuberance, defining a laterally inwardly projecting spacer 14A and configured at a proximal end thereof, with a respective protuberance defining a laterally inwardly extending spacer 14A′. The spacers 14A and 14A′ abut the outer faces of the respective skins 4 such that laterally inner faces 16 of the flanges 15, which faces are between the spacers 14A and 14A′, are spaced slightly from the respective skin outer surfaces adjacent thereto, such that voids 21A are defined between the adjacent faces. The adhesive 20 is applied so as to occupy each void 21A, whereby it is reliably retained between the opposing faces which it bonds (in this case the flange face 16 and cover outer face between which that void is defined) the voids 21A thus conferring advantages consistent with those conferred by voids 21 as described above.
The spacers 14A, like spacers 14, extend the entire length of the respective flange portions 15, though could instead be intermittent along the length without departure from the invention. Likewise, the spacers 14A′, like spacers 14, extend the entire length of the respective flange portions 15, though could instead be intermittent along the length without departure from the invention.
In the example shown in
In an alternative arrangement embodying the invention, the structural component to which the assembly comprising the panel 1 and connector 10A is tied down can be something other than a slab—for example, a floor frame, which frame may be timber, in which case it may be appropriate that the fasteners 60 take the form of screws or bolts, or which may be metal, in which case it may be appropriate that the fasteners 60 take the form of bolts. In either scenario in which the fasteners 60 comprise bolts, it will often be appropriate that the shank of the bolt in each fastener extend through the frame member and the fastener include a nut, possibly together with a washer at the distal end of the shank to abut the bottom face of the frame member, so that uplift forces and/or other upward forces in the panel 1 are transferred through that face. It is also possible that the tension-resistant engagement can be instead effected, or enhanced, by bonding and/or fusing the lower face of the web portion 11A to the upper surface of the component 50A against which it is received. In one example, in which the component and web portion are made of fusible material, the binding/fusion may be effected by heat and/or chemical fusion and/or welding together of the abutting faces of the web portion 11A and component—either intermittently continuously along the length of the web portion 11A.
In any case, the downward (anchoring) loading exerted by the slab, floor frame or other underlying structure defining the “component” on the lower end of the panel is directed, by the connector 10A/connection, to the skins 4. In this case, the loading so directed does not comprise any loading transferred, as such, from the substrate to the skins, since the connector eliminates any need for tensile loading on the connection, resulting from upward loading on the panel 1, to be borne through the lower end face of the substrate 3.
Shown in
The web portion 11B and flange portions 15B define a downwardly opening cavity into which the substrate 3 at the upper edge/end of the panel 1 is closely received, whereby one of the flanges 15B extends parallel and adjacent to the inner surface of one of the coverings 4, and the other flange 15B extends parallel and adjacent to the inner surface of the other covering 4. More particularly, each flange is received in a respective slot machined (e.g. routed) into a laterally outer portion of the substrate material, whereby laterally inner faces of the flange portions 15B are received against/adjacent to, and in alignment with, respective laterally outward faces of the substrate formed by the machining and defining laterally inner faces of the respective slots, and the laterally outer face of each flange is received adjacent to/against, and extends in alignment with, the laterally inner face of the respective skin 4 which is exposed as a result of the machining and defines a laterally outer face of the respective slot. Adhesive 20 is received in each of the slots 20 to bond the laterally outer face of the flange portion 15B therein to the laterally inner face of that slot defined by the exposed laterally inner face of the skin 4. Adhesive 20 is also applied between the web face 13B and lower face of the structural component 50B arranged atop the panel 1, that component in this particular example being a like panel (1) extending perpendicular to and supported on the panel 1, to bond the lower face of the component 50B to the web portion 11B. In this particular example, the upright panel 1 may be that of an internal wall in a building and the panel 50B a ceiling and/or roof panel of the building, the connector 10B thus defining a top plate.
The adhesive 20 received in the slots may additionally comprise adhesive 20 which bonds the flange inner lateral faces to the outer lateral faces of the substrate.
In this example, the connector 10B/connection directs, to the upright panel skins 4, downward loads, and any temporary upward loads, exerted on the upright panel 1 by the component 50B.
Applied to the lower end of the panel 1 is an end plate P, having a web W an upper face of which is secured to an end face of the substrate 3 at the lower end by adhesive 20, and parallel upwardly extending flanges F which are received in slots, likewise machined into the substrate material, in a manner such that laterally and outwardly projecting end portions of the web W receive thereagainst lower ends of the respective skins 4. The end plate P, advantageously, ensures satisfactory directing, to the skins 4, of upward loading exerted on the panel by the support structure as a result of the lower end of the panel resting against that support structure.
The connector 10B may, without departure from the invention, be configured with protuberances, the kind previously described, at the distal ends of the flanges and on the side(s) thereof which are bonded within the respective slot, and/or at/adjacent lateral edges of the web portion 13B, defining adhesive-holding voids conferring advantages as described above.

The connector 10C is configured in the form of an I-beam comprising a web portion 11C, opposed portions of which define a first face 12C and a second face 13C, and parallel flanges 15C each connected to a respective end of the web 12C and being perpendicular to that web, each flange 15C having opposed flange portions 15C′, the web portion face 12C and the two flange portions 15C′ which project in the direction in which that face faces defining a cavity into which the edge 2 of the panel 1 is closely received. Correspondingly, web portion face 13C and the flange portions 15C′ which project in the direction in which that face faces, define a cavity into which the edge 2 of the panel 50C is closely received. In the particular example shown, the connector 10C/connection is one capable of transferring, to the panel 1, loading in the panel 50C and to direct that loading to the skins 4 of the panel 1. The flange portions 15C′ between which the edge of panel 1 is received are configured at their distal ends with protuberances defining spacer portions 14C which abut the outer faces of the respective skins so that adhesive-retaining voids 21C are defined between adjacent surface portions of the flanges and skins bonded by the adhesive 20. The distal ends of the other flange portions 15C′ are likewise configured with spacers 14C such that corresponding adhesive-retaining voids are defined between those flanges and the skin faces of the panel 50C bonded by that adhesive (though, again, the spacers 14C/voids 21 could be omitted without departure from the invention).
In the particular example shown, the connector 10C/connection transfers loads in the panel 50C to the panel 1 and directs them to the skins 4 of the panel 1, particularly tensile loads in the direction away from and perpendicular to web face 13C (which loads are transmitted from the panel 50C to the flange portions 15C′ between which that panel is received, by the adhesive 20 bonding that panel to those flange portions. The loading also includes compressive loading in the panel 50C in the direction towards and perpendicular to the face 13C, which loading is transferred by compression of the web 12C and the abutment between the face 12C thereof and the end faces/edges of the skins 4 received thereagainst. The tensile/compressive loading may instead be created by moment loading, about an axis extending parallel to the panel edge, in which case the compressive load transfer path just described will be through one end of the web 11C and the tension load transfer path just described will be through the flange 15C at the opposite end of the web. Typically, the bending loading in question will comprise downward loading in the end of the panel 50C, resulting from the weight of the panel 50C, so that the compressive load transfer is effected through the top flange 15C and the tension load transfer is effected by the bottom flange 15C. The loading transferred from the panel 50C to the skins of the panel 1 may additionally comprise shear loading parallel to the web faces 12C and 13C. That shear loading may result from torsion about an axis perpendicular to those faces and/or horizontal/vertical loading.
Advantageously, the upper flange 15C, which extends throughout the lengths of the panel edges forms a cap which conceals the ends of the panels, contributing to aesthetics. Also, the adhesive which bonds that flange to the upper skins 4 of the panels provides a seal against 2 ingress of water into the connection.
In particular embodiments of the invention comprising connection of panel edges via a connector, it is not necessary that the connector engage both skins of the panel 1, as is the case with the example shown in
The arrangement shown in
The connector 10D1 comprises a web 11D1 and opposed flange portions 15D which project divergently from a proximal end/edge of web 11D1 so as to extend parallel to, and be received against, respective ones of the upper/exterior skins 4 of the panel 1 and panel 50D. Each flange is configured, at a distal end/edge thereof, with a spacer 14 of the kind previously described, whereby a respective void 21 is defined between a face of the flange and adjacent face of the skin 4 of the respective skin to which it is to be bonded, adhesive 20 being applied within the void.
The connector 10D1 not only directs, to the upper skin 4 of panel 1, loads exerted by the panel 50D (particularly loads through an outer lateral side portion of the panel 50D, but also, advantageously, defines a ridge cap, the adhesive 20 bonding the flanges of that ridge cap to the outer skins 4 providing a seal against ingress into the upper connection. A compressive load exerted on the web 11D1 by the upper lateral portion of panel 50D will be directed by the web 11D1 both to the end face of the upper skin 4 of panel 1 abutting that web and to outer side face of that skin via the flange portion 15D1 and the adhesive bonding it. Tension forces exerted by that portion will be transmitted to the upper portion skin 4 of panel 1 by the interconnection between that skin and the flange 15D1 bonded to it by the adhesive 20. The included angle, A1, between the flange portions 15D1 is on the side of the flanges from which the web 11D1 projects.
The connector 10D2 comprises a web 11D2 and flange portions 15D2 which diverge from a proximal end of the web 11D2, so as to extend parallel to respective ones of the lower/interior skins 4 of the panels 1 and 50D. The included angle, A2, between the flange portions 15D2 is on a side of those flanges which is opposite to that from which the web 11D2 projects.
The flanges 15D2 are also configured at their distal ends/edges with spacers 14 arranged to abut the external surfaces of the lower skins 4, whereby there are defined between a face of that flange and the respective skin surface adjacent to it respective voids 21 which retain adhesive 20 applied therein and bonding the flange and skin. Compressive loading exerted through a lower/inner lateral side portion of the panel 50D will be taken through the side face of the web 11D2 abutting that portion and directed by that web to the lower skin 4 of the panel 1 and transferred into that lower skin by abutment of the web between the end face of that skin as well as by the bond between the outer surface of that skin and the flange received against that skin. Other loads through that lower portion will be transferred to the panel 1 and directed to the lower skin thereof in the same manner as the loads in the upper lateral portion of the panel 50D are transferred to the upper skin of the panel 1 by the upper connection.

The laterally inner flange 15E is configured in the same form as the right-hand flange 15 in the arrangement shown in
Advantageously, owing to the receipt of the laterally outer flange 15E into the slot, it is concealed by the external skin 4 and the junction between that flange and the outer skin 4 faces downwardly so that water/moisture ingress into that junction may be avoided.

The diagonal panel 1 (to the outer end of which the connector 10I is secured) is a roof panel a portion of which cantilevers (as illustrated) to define an eave. The connector 10I comprises a web 11I a laterally inner face of which is received against the end face of the inclined panel 1 at the edge 2, and opposed upper and lower flange portions 15I projecting from upper and lower ends, respectively of the web 11I to be received against upper and lower skins 4 of the inclined panel 1. The flange portions 15I are angled with respect to the (upright) web 11I to the same extent that the outer surfaces of the skins 4 are angled with respect to the (upright) end face 5 of the panel 1. The flange portions 15I′ are configured at distal ends thereof with spacers 14, resulting in a void 21 to receive the adhesive 20 bonding the flange portions 15I to the upper and lower skins 4.
The connector 10I comprises, in addition to web portion 11I, an additional web portion 11I′ the web portions 11I and 11I′ being defined by a single web of the connector 10I. The web portion 11I′ projects downwardly from the lower end of the web portion 11I and defines a drip or drainage line/bridge along which water running down the laterally outer face of the connector, defined by the web, is precluded from ingressing into the connection.
The connector 10I further comprises additional flange portions 15I′ which project laterally inwardly from, and perpendicular to, the web, the additional flange portions 15I′ being arranged below the lower flange portion 15I. The flange portion 15I′ and that portion of the web from which they project define a laterally inwardly opening cavity which receives a laterally outer end of the soffit connection bracket 50I. The faces of the cavity defined by the flange portions 15I′ can, if appropriate, be bonded to upper and lower faces of the bracket 50I. Loading exerted horizontally against the web 11I by the soffit connection bracket 50I (whether laterally outward or laterally inward) will be transferred by the connector 10I to the inclined panel 1 and directed to the skins thereof via the web and flange portions 15I.
The connector 10I, advantageously, defines a cap received over the panel edge and concealing the end face 5, contributing to aesthetics.

Uplift loading exerted (via the ceiling panel 1) by the roof on the wall panel 1 is directed to the flanges 15J and thence to the skins 4 of the upright panel 1 through the bonds between those flanges and skins.

In this embodiment, the connector 10O defines a side mount frame, or a side member of a mount frame, for the pane. The connector 10O has a web portion 11O, which is received between the opposed end faces of the edges of the window pane 50O and panel 1, and may be secured to either or each of those faces via adhesive 20 in a respective gap G between it and that face. The connector 10O includes a flange portion 15O projecting from an inner upright edge of the web 10O and perpendicular to that web, the flange portion 15O being configured at its distal end/edge with a spacer 14 received against the inner upright face of the pane 50O, whereby defined between that face and a face of the flange portion 15O opposing it is a void 21 containing adhesive 20 bonding the two faces together (the material from which the window pane is made being bondable by the adhesive 20). The connector 10O further comprises a further flange portion 15O′ projecting from inner upright end/edge of web 10O and perpendicular to that web, in a direction opposite to the flange portion 15O, the flange portion 15O′ being configured at its distal end/edge with a spacer 14 received against the outer face of the inner skin 4 of the panel 1, whereby defined between the two faces is a void 21 containing adhesive 20 bonding the two faces together.

The connector 10P defines a bottom mount frame, or a bottom member of a mount frame, for the pane; in the latter case, both that connector and the connector 10O may be interconnected so as to define side and bottom members, respectively of a single said mount frame. The connector 10P is identical in cross-section to connector 10O with the exception that it further includes an additional flange portion 15O″ projecting from a distal end portion of web 11O and perpendicular to that web portion, to be received over an upper portion of the outer skin 4 of panel 1, and which may be secured to that portion via adhesive 20 between it and that portion. The web portion 11O of the connector 10P is received between the opposed horizontal end faces of the edges of the window pane and panel, and may be secured to either or each of those face via adhesive 20 in a respective gap G between it and that face. The spacer 14 with which the distal end/edge of flange portion 15O of the connector 10P is configured is received against a lower portion of the inner upright face of the pane 50O, whereby defined between that face and the face of the flange portion 15O opposing it is a void 21 containing adhesive 20 bonding the two faces together. The spacer 14 with which the distal end/edge of flange portion 15O′ of the connector 10P is configured is received against an upper portion of the face of inside skin 4 of panel 1, whereby defined between that face and the face of the flange portion 15O′ opposing it is a void 21 containing adhesive 20 bonding the two faces together.

The connector/connection in each preferred embodiment of the invention described herein with reference to the accompanying drawings, advantageously, engages a/each skin of the panel to which it is applied so as to direct, to that skin, loading exerted on the panel by the said component connected to the panel via the connector/connection (the loading including or consisting of loads through the connector itself), the skin 4 being braced against distortion/buckling by the substrate 3 and being made of a material which is stronger than the substrate material and thus, unlike the substrate/substrate material, being apt to bear that loading—be it compressive, tensile or shear (translation or torsional) loading. In transferring loads to at least one lateral side of the panel, the connection/connector may function in the nature of a lintel.
The/each skin 4 in each composite panel described herein with reference to the drawings can be satisfactorily braced against buckling under compressive loading on that panel in any of the various applications to which it is suited. The substrate 3 in each panel affords the panel overall sufficient thickness such that the panel itself will not to buckle under compressive loading on it in applications to which it is suited.
Moreover, the substrate 3 confers to the panel a thickness sufficient to afford the panel a high section modulus and/or second moment of area and corresponding high load-bearing capacity whilst, given its low density as compared with a substrate of the same material if continuous/solid throughout, conferring relatively little weight to the panel. Furthermore, the strong skins defining the outer sides of the panel afford the panel a sufficiently high plastic and/or elastic section modulus for any of the various applications to which the panel is suited. The strength of the skins and thickness of the panel together confer to the panel a relatively high racking load bearing capacity.
The microstructure of the substrate material in the preferred embodiments described and illustrated herein, given its porosity/the distribution of interstices therethroughout, contributes to the thermal insulation properties of the panel, rendering the panel especially suitable to applications in hot or cold climates, particularly such applications in which it forms a barrier between a building interior and exterior, and/or contributes to sound attenuation properties of the panel.
In the method of manufacturing the panel 1 in accordance with a preferred embodiment of the invention, each of opposite sides of a substrate is bonded to a respective sheet section, whereby the panel 1 comprises opposed skins 4, each comprising a respective one of the sheets, and the core 3, comprising the substrate.
More specifically, one of the sheet sections is laid down on a vacuum press and bonding agent (preferably adhesive/glue but possibly, for example, resin) is applied to the exposed surface thereof. The substrate 3 is then laid over that surface. Adhesive is applied to the exposed side of the substrate 3 and/or the other sheet section, and the other sheet section is laid over the substrate 3.
The press is thereafter operated to clamp the sheet sections against the respective sides of the substrate/core 3. Either or each side of the substrate 3 and/or a side of the respective sheet section which received is against that side is configured with grooves (not shown), each of which may have a width and depth both of which are 3 mm, such that excess bonding agent flows into and along at least one of the grooves and, should it be present in a sufficient volume, escapes from between the sheet sections, through at least one of the groove ends.
The substrate/core 3 of the panel according to each of the embodiments described and illustrated herein is extruded polystyrene foam, such as that which is supplied under the name XPS40 by Lavender CE Pty Ltd in Wacol, Queensland, Australia, details of which are as follows:
The skins/coverings 4 in the panels according to each of the embodiments described and illustrated herein comprises glass-fibre-reinforced plastic, such as that which is supplied under the name LAMILUXplan by the LAMILUX Heinrich Strunz Group in Germany.
Where a given skin 4 is to be exterior and visibly exposed in the building/assembly—e.g., the panel 1 of which it forms a part defines or forms part of an exterior wall of the building/assembly, or defines or forms part of a roof of the building/assembly, or defines or forms part of a floor of the building/assembly—the skin which is visibly exposed and exterior preferably has product details as follows:
Advantageously, the exposed surface of such skin material is grainy or sandpaper-like, providing (on the/each side of the panel at which this skin material is provided) a (cement) “rendered” appearance and/or, in the case of the skin defining the surface of the floor, affording the floor surface anti-slip characteristics.
Where a given skin 4 is to be interior and visibly exposed in the building/assembly—e.g., the panel 1 of which it forms a part defines or forms part of a wall (interior or exterior) of the building/assembly which bounds (at either or each side thereof) an occupiable interior space or living area, or defines or forms part of a ceiling of the building/assembly—the skin which is exposed and interior preferably has product details as follows:
Advantageously, the exposed surface of such skin material is matt and relatively smooth, providing (on the/each side of the panel at which this skin material is provided) a “plastered” appearance.
Where a given skin 4 is to be concealed/not visibly exposed in the building/assembly—e.g., the panel 1 of which it forms a part defines or forms part of a roof of the building/assembly, or defines or forms part of a floor of the building/assembly or defines or forms part of a ceiling of the building/assembly—the skin which is concealed/not exposed and (the lower skin in the case of said roof or said floor, and the upper skin in the case of said ceiling), the skin which is concealed/not exposed may have product details as follows:
The exposed surface of such skin material is adequate, without affording the panel any particular aesthetic characteristic, such being unnecessary given the skin (on the/each side of the panel at which this skin material is provided) is not seen in the building/assembly.
The adhesive used to secure the skins 4 to the core/substrate 3 is a polyurethane-based adhesive, such as that which is supplied under the name MACROPLAST UK 8101/MACROPLAST UK 5400 by Henkel AG & Co. KGaA in Germany. It will be appreciated the adhesive can vary, and be readily selected by a person according to the materials used for the skin(s) and core/substrate.
Advantageously, the panel can be produced in large sizes. A single such panel may, for example, be sized such that a length thereof is up to 23 m and a width/height thereof is up to 3 m, whereby the panel can be transportable, in a laid-down orientation, by a flatbed truck. Either or each of the length and width/height dimensions may exceed these values particularly where such transportation is not required.
It will be clear from the foregoing that preferred embodiments of the invention provide structural insulated panels (SIPs) and sandwich panels, including finished such panels, and means of manufacturing and interconnecting same.
Throughout this specification, including the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments.
