PANELLING
This invention relates generally to panelling and to processes of fabricating panelling. More particularly, the invention relates to panel members and panel structures utilising such members which can be combined to form extended panels for use in such applications as acoustic panelling, fire walls, duct silencers and lay-in ceilings and walls.
Acoustic panels are generally constructed by joining together two separate panel members in spaced apart and opposed face-to-face relation such that the panel members form opposite, outer walls of a hollow panel structure which can be left hollow or filled with an acoustic deadening material as required. Each individual panel is furthermore typically configured to be matingly interconnected with an adjacent panel at an adjoining edge region thereof.
Panels for other applications are typically of similar construction.
The fabrication of acoustic and other panelling usually involves time consuming construction methods, both in respect of forming the individual panel members and also in respect of the assembly of the panel structures from their component parts. Much of the assembly time is involved in methods of securely fastening the two side panels together, which typically involves a combination of extensive pop riveting, spot welding and metal crimping.
The fabrication of the individual panel members is generally carried out by roll forming of sheet metal, although other methods, such as brake pressing are also used. These procedures can be relatively time consuming. Accordingly, it would be desirable to provide a new panel structure and a method of fabricating panel members for use in acoustic and other panelling applications which can provide simplicity, speed and economy in both fabrication and assembly.
According to one aspect of the present invention there is provided a panel member for a panel structure. The panel member may be formed from sheet VAT:WinwordVoletPhilNodelete\Ofiac.doc material, such as sheet metal, and defines an outer panelling surface extending between first and second opposite edge regions of the panel member. The first edge region defines a slot adjacent an inner surface of the panel member, which slot is substantially co-extensive with that first edge region. The slot is adapted to receive a coupling member with which the panel member can be coupled to a second opposite panel or a support. The slot includes retaining means for engagement with complementary fastening means on the coupling member to create a positive connection with the coupling member and retain the coupling member in the slot. The second edge region of the panel member is formed with geometry complementary to the first edge region such that adjoining first and second edge regions of adjacent panel members overlap and nest next to each other so as to minimise interruption between the outer panelling surfaces of the adjacent panel members.
According to another aspect of the invention there is provided a panel structure comprising a pair of first and second panel members as described above arranged spaced apart and in opposed relationship such that the first edge regions of the panel members are located opposite each other and the second edge regions of the panel members are located opposite each other. The panel structure includes a channel member for coupling the panel members together at the opposite first edge regions. The channel member preferably has a generally "square U"-shaped geometry with a pair of projections interconnected by a base. Each of the projections is received within a respective slot formed at the first edge region of each panel member and fastening means provided at each channel member projection engages with each slot fastening means. The interconnected first edge regions of the panel members combine to form a female mating edge of the panel structure. The opposite second edge regions are joined together to form a male mating edge of the panel structure. The male mating edge of the panel structure is thereby able to nest within the female mating edge of an adjacent panel structure to provide smooth transition between panelling surfaces of the adjacent panel structures.
VAT:Winword\Violet\Phil\Nodelete\Ofinac.doc -4- According to a further aspect of the present invention there is provided a panelling system including: a plurality of panel members, each panel member being as described above, with the panel members adapted to be arranged spaced in pairs, spaced apart and in opposed relationship such that the outer panelling surface of each panel member faces away from the other panel member of the pair and such that the first edge regions of the paired panel members are located opposite each other and the second edge regions of the paired panel members are located opposite each other; a channel member for coupling the paired panel members together at their opposite first edge regions, the channel member being of a generally Ushaped configuration having a pair of projections upstanding from a base interconnecting the upstanding projections, each of the projections being adapted to be received within a respective slot at the first edge region of each panel member and having fastening means adapted to engage with the retaining means of each slot; and wherein the interconnected first edge regions of the panel members combine to form a female mating edge of a panel structure and wherein the opposite second edge regions of the panel members can be joined together to form a male mating edge of the panel structure, the male mating edge being configured to nest within the female mating edge of an adjacent panel structure to provide a close fit and a smooth transition between the outer panelling surfaces of the two panel structures.
In yet another aspect of the invention there is provided a method of fabricating each of the components of the panel structure. In a preferred form of the invention the panel members and the channel section will be roll formed from a suitable sheet metal such as galvanised steel, stainless steel or aluminium, although other sheet materials are also suitable. The thickness of the sheet VAT:WinwordViolet\Phi\Nodelete\Ofirc.doo
I
material will depend upon the material used. Galvanised steel of between 0.6 and 1.2 mm gauge is preferred.
In a preferred embodiment of the invention, the first and second panel members will be substantially identical and each formed from a single piece of sheet material. The first edge region of the panel member is preferably formed in a succession of roll forming stages wherein an edge portion of the sheet is progressively folded back through approximately 180 degrees thereby forming a slot adjacent an inner surface of the panel member extending along the first edge region.
The folded portion of the first edge region preferably includes a raised portion in the form of a ridge or similar extending along its length and defining a recess within the slot. Preferably this will be located toward the open end of the slot.
This recess is configured and situated to receive an appropriately located and dimensioned bead in a projection of the channel member as described further below. Such inter-engaging beads and recesses are examples of the complementary retaining/fastening means referred to previously.
The edge of the folded portion at the open end of the slot is preferably angled inward away from the slot at an angle preferably greater than 45 degrees and more preferably about 80 degrees. This angled edge provides an added degree of stiffness to the edge region and also facilitates the insertion of the channel member into the slot. The first edge region of the second panel member is typically a mirror image of the first edge region of the first panel member.
The channel member is preferably of the same material as the panel members.
It is generally of a "square U"-shaped configuration with the base and the two projections of the member each being substantially planar. Preferably the two projections of the channel member will be at 90 degrees to the base.
Preferably the channel member will include along each projection a raised VAT:Winwordiolet\PhiNodelete\Ofinac.doc portion or bead which protrudes such that in use it locates into the respective recess extending along the slot.
The dimensions of the channel member will vary depending upon the dimensions of the panel members and the desired width of the overall panel structure. By varying the width of the channel member base, the width of the overall panel structure will also vary. The length of the channel member projections will be such that they extend well into the slots and preferably beyond the recess formed for engagement with the channel members.
When assembled, the combination of the first and second panel members and connecting channel member combine to form at one edge of the panel structure, a large channel being the female mating edge formed from the base of the channel member and the respective folded portions of the panel members. This channel opening is designed to receive the male mating edge of another panel structure. Further panel structures can be added, edge to edge to create the desired width of panel.
Accordingly, the male mating edge of the panel structure is configured to provide a close fit with the female mating edge formed in the first edge region.
Preferably the second edge region of each of the two panel members will have a generally stepped configuration wherein there are two steps parallel to the outer panelling surface thereby giving a three level structure consisting of the outer panelling surface, an intermediate level and an inner level. In a more preferred form, the sheet material of the inner level is formed with an indentation such that when a pair of panel members are combined to assemble the panel structure the respective indentations can be aligned to locate the panel members in the proper position with respect to each other.
The respective second edge regions of the two panel members are dimensioned such that when the two panel members are joined together, the external width of the panel at the intermediate level is such that it is receivable VAT:WinworViolet\Phit\Nodelete\Ofinac.doc into the female mating edge of the panel structure. Preferably, the external width at the intermediate level step is only slightly less than the internal width of the channel of the female mating edge such that a friction fit is obtained. The closeness of the fit between the male and female mating edges of the panel structures ensures good thermal and acoustic integrity between adjoining panel structures.
The width of the panel structure at the male mating edge can be increased either by altering either or both of the step heights between the inner and intermediate levels or by inserting a spacer of appropriate width between the respective inner levels. This spacer may be of "square U" shaped channel.
Any variation in the dimensions of the male mating edge must be matched by corresponding variation in the channel member connecting the respective first edge regions of the two panel members.
In a preferred configuration the length of the intermediate level is slightly less than the distance between the opening of the female mating edge and the ridge which extends along folded portion of the respective first edge regions.
A preferred method of fabricating the panel members is by roll formation in a continuous process. As the person skilled will appreciate roll forming apparatus is normally custom designed to produce the particular section required. The preferred method of fabrication produces the desired profile in a series of 9 steps in which the two ends of the sheet are simultaneously and progressively rolled into the desired profile. By this simple one step procedure, the panel member according to the invention, is able to be produced at a rate of approximately 10 seconds/per metre.
As the person skilled in the art will appreciate, the roll forming process involves a flat coil being fed into the roll forming machine whereby it passes through the various stages of roll forming. The number of stages ensure that the desired shape and stability in the material flow is obtained. After the material has VAT:WinwordVWiolet\PhilNodelete\Ofinac.doc passed through the roll forming stage the machine is set to cut the material to the required predetermined length.
The panel members can be produced in any length required. Typically, this will be in the order of up to about 5.5 metres, however, longer lengths can be produced if necessary. The panels may also be formed by other means such as brake pressing and may be fabricated in other than a single sheet.
In one preferred application, the panel structures of the invention are used to provide sound proofing. In such an application, the hollow panel structure will preferably include a sound absorbent material such as wool or other material as is known in the art. To assist its acoustic properties, the wall section may be perforated. Preferably the perforations will be made in the sheet material prior to it being roll formed. In that case the perforations will be restricted to the panelling surface intermediate the two edge regions of the sheet.
Acoustic panelling is but one of many useful applications of the panels of the invention. Other applications utilising the composite panel structure include fire walls where the cavity between the panel member is filled with a suitable fireproof material. The cavity may also be filled with other materials, such as concrete, depending on the application.
In a further alternative application, the panel members can also be usefully utilised singly where it is not necessary to have a hollow two sided structure.
For example, the wall members can be used to form "lay-in" ceiling or wall panels. In such an application, channel members as described above may be attached to a roof rafter or cross beam or similar support member by conventional means. This provides a channel member which extends down below or out from the support member. All panel members can then be fitted to the channel member in an analogous manner to that described above in relation to the composite structure. In such an application, the first edge region of a panel member is fitted over the lower (in a ceiling application) projection of VAT:WInword\Violet\PhiNNodelete\Ofinacdoc
I
the channel member. The second edge region of another panel is then fitted or nested inside the first edge region of the first panel member and the first edge region of the second panel member fitted around a suitably positioned second channel.
In a further analogous application, the panel members can be used in combination with appropriately configured channel sections as duct silencers.
For a better understanding of the present invention, a preferred embodiment of the invention is hereafter described by way of illustrative example with reference to the accompanying drawings in which like reference characters designate like features and in which: Figure 1 is a sectional end view of a panel member according to an embodiment of the present invention; Figure 2 is a sectional end view of a panel structure according to an embodiment of the present invention; Figure 3(a) to 3(i) is a series of sectional end views showing the progressive formation of a panel member according to the present invention.
Referring firstly to Fig. 1 of the drawings, the invention provides a panel member (10) for use in a panelling system. The panel member (10).is formed.
to any desired length and width from a substantially rigid sheet of metal such as galvanised steel having a thickness in the range of about 0.6 mm to about 1.2 mm. The panel member (10) has an outer panelling surface (11) extending between a first edge region (12) and an opposite second edge region The first edge region includes a folded portion (14) which is folded back approximately 1800 onto an inner side of the panel member (10) to define a slot The slot includes an indentation or recess (16) located towards the open end of the slot The recess (16) may extend along the length of the panel member Furthermore, the free edge of the folded portion (14) is angled inwardly away from the slot to form a flange (17).
VAT:Winward\Vioet\PhiNodelete\Otlnacd The second, opposite edge region (13) of the panel member (10) is formed in a stepped configuration and includes two steps substantially parallel with the outer panelling surface namely an intermediate step (18) and an inner step The geometry of the intermediate step (18) is complementary to the configuration of the first edge region (12) to the extent that at least a part of the first edge region (12) of an adjacent panel member (10) is adapted to neatly overlap and nest with the second edge region (13) at the intermediate step (18) so that the outer panelling surfaces (11) of the adjacent panel members are substantially co-planar with minimal interruption or discontinuity therebetween.
The intermediate level step (18) is connected with the outer panelling surface (11) by a first face portion (21) which is disposed at an angle of about 600 to the outer surface. The intermediate level step (18) is connected to the inner level step by a second face portion (22) which is angled at approximately 800 to the intermediate level step. Furthermore, the inner level step (19) includes a Vshaped notch (23) approximately at a mid-point therealong.
Referring now to Fig. 2 of the drawings, there is illustrated a panel structure (100) according to the present invention. The panel structure (100) includes a first panel member (10) as illustrated in Fig. 1 paired with a second panel member The second panel member is a mirror image of the first panel member (10) except in respect of its notch The V-shaped notch in the second panel member points inwardly whereas the notch (23) in the first panel member (10) points outwardly. The notches (23, 23') are therefore able to interengage in the manner shown in Fig. 2.
The panel structure (100) includes a channel member (30) interconnecting the first edge region (12,12') of the two panel members (10,10') which are arranged spaced apart and opposite one another. The channel member (30) has a generally "square" U-shaped cross-section and includes two projections (31) upstanding from a base (32) of the channel member. The base (32) is flat and the projections (31) extend substantially at right angles from the base and have VAT:WinwordWiolet\Phil NodeletelOfinac.do -11 a length which is slightly less than the depth of each slot Each of the projections (31) includes a raised section or bead (33) which is adapted to be received in the recess (16) formed in the folded portions (14, 14') of the first edge regions The flanges (17,17') assist in the insertion of the projections (31) of the channel member (30) into the respective slots (15,15').
The recess retaining means (16,16') and the channel member beads (33) provide a positive snap fit between the channel member (30) and the panel members This snap fit provides a sufficiently positive connection to render unnecessary other extensive and time consuming securing methods such as pop riveting, spot welding and the like which would otherwise be required.
After the interconnection of the panel members (10,10') with the channel member (30) at the first edge regions the panel members are placed in proper alignment by interengagement of the two V-shaped notches (23,23').
Then, in order to permanently secure the panel members and the channel member together, the first edge region of each panel member (10,10') is clinched across the slot (15,15') at either end of the channel member to prevent the channel member from sliding longitudinally in the slots. Furthermore, the top and bottom regions of the interengaged inner level steps (19,19') are also clinched.
As can be clearly seen in Fig. 2 of the drawings, once assembled the panel structure (100) has a relatively large channel forming a female mating edge between the folded portions (14,14') of the first edge regions and a protruding nose forming a male mating edge (60) having parallel side wall portions formed by the intermediate level steps The external width of the male mating edge (60) is marginally less than the internal width of the opening in the female mating edge Accordingly, a plurality of panel structures (100) can be combined in a planar array with the male mating edges nesting within the female mating edges (50) of adjacent panel structures to VAT:Winword\Violet\PhilNodelete\Ofinac.do -12provide a substantially continuous outer panelling surface (11,11') across the panelling array.
Finally, Figs 3a to 3i illustrate the various stages of deformation of a sheet of metal during a nine stage 'cold' roll forming operation in which both of the opposite first and second edge regions (12,13) are continuously roll formed to provide a panel member (10) as shown in Fig. 1 at the end of the ninth and final roll forming stage.
It is to be understood that various modifications, alterations and/or additions may be introduced into the construction and arrangement of the parts specifically described and illustrated herein without departing from the spirit or ambit of the present invention.
