Abstract
ABSTRACT OF THE DISCLOSURE
A decking panel engageable edge to edge with an identical panel. The panel comprises a panel portion flanked along its side edges with upstanding channels, one of which is a male channel, the other a female channel. The cross-sectional shape of the male channel along one side has an upwardly extending portion and a return flange located over the panel portion. The cross-sectional shape of the female channel along the other side also has an upwardly extending portion and a return flange, but said female return flange is beyond the panel portion. The panel is so constructed and arranged that when the male channel flange of one panel is within the female channel of a second panel of similar cross-sectional configuration in a decking, the two inter-engaged channels have a common mouth directed towards the upper surface of the first said panel. This avoids the downwardly directed, narrow, deep channels of previous decking panels. These narrow, deep channels can form havens for insects.

Description
:~ o~ 5 This invent.ion relates to a decking panel which is useful for decking a structure wherein it is de~ired to span considerable distances.
5. It is already known to produce decking panels capable o~ spanning considerable distances, and for example the decking panel described in the Australian Patent of Handford 261,896 is one such decking panel. Deflection of such a decking panel over a span is restrained, inter alia, by 10. interengagement of an upstanding rib which extends along one edge of one decking panel within a channel extending along the other edge of a similar adjacent deckiny panel, the Handford specification describing one of a number of d.ifferent types of decking panels which u~ilise this broad 15. general featuxe.
One of the features of previously proposed decking panels however is the existence of a narrow but deep channel having a downwardly directed mouth formed between adjacent decking panel members, and these channels are known to -~
20. constitu'e havens for certain types of insects.
One object of this invention is to improve previously proposed configurations in a decking panel, such that it is possible to avoid having a channel direct~d downwardly.
. " . . . . .
25. Briefly in this inventlon two similar decking panels are interlocked by a return flange of a male channel engaging within a female channel formed by a second return flange exten~
ding along the opposite edge of a similar panel, in uch a '',. ~.

~S~325 way that when so assembled the two channels have a common mouth which is directed towards the upper surface of the first panel, whereby the need for a downwardly directed channel facing into a building is avoided.
More specifically in one aspect of this invention, a decking panel which is engageable edge to edge with an id~ntical panel, comprises a panel portion flanked along its side edges with upstanding channels, one of which is a male channel, the other a female channel, the cross-sectional shape of the male channel wall along one side having an upwardly extending portion which slopes upwardly and out-wardly away from said panel portion and merges into a downwardly and inwardly sloping return flange which is located over the panel portion, such that the male channel wall defines substantially a 'V' formation, the cross-sectional shape of the female channel wall along the other ` ~ -side also having an upwardly extending portion, a return ...
horizontal portion, an upwardly extending channel web, an outwardly extending channel web, a return flange, and an `
inturned tongue, said female return flange being beyond said panel portion, so constructed and arranged that when said ;-~
male channel flange of one panel is within the female channel of a second panel of similar cross-section~con- ~ ~;
figuration in a decking, the two interengaged channels have -a common mouth directed towards the upper surface of the first said panel, said upwardly extending portion of the male channel wall, where it merges into said downwardly and inwardly sloping return flange, bearing against the inner surface of said upwardly extending channel web of the female ~ ~ ~
30 channel wall, and said return flange of the male channel web ~ ; `
bearing against the inner surface of said inturned tongue. ~ -~ -3-~L~35~325 In this invention the upwardly extending flanges of two similar decking panels are contiguous, when the return flange of the male channel of one panel is within the female channel of a second panel, so that there is no mouth S directed downwardly into a building.

An embodiment of the invention is described hereunder in some detail with reference to and is illustrated in the accompanying drawings, in which Fig. 1 is a perspective section of portion of a roof Eormed from interengaging decking panels which are in accordance with this invention, E'ig. 2 is an enlarged section illustrating one method of assembly of two adjacent panels, Fig. 3 is an enlarged section showing the return flange of one panel with a second channel of a second panel of similar cross-sectional configuration, and Fig. 4 is a view similar to Fig. 2 but showing a second assembly method.
- In a preferred embodiment of a decking panel 10 is arranged to interlock with an adjacent decking panel of similar cross-sectional configuration. Each decking panel 10 is provided with a substantially 1at hand portion 11 which, when used as a roof/ceiling combination, is the lowermost portion. The central part of the flat portion is provided with an upwardly formed V crimp 12 in order to impart stiffness to the otherwise flat panel portion. A
first side edge of the flat panel portion 11 terminates in an upwardly extending portion 13 and a return flange 14 which is located over the panel portion 11, while the second side also terminates in an upwardly extending portion designated 15 and a return flange 16, but in contrast to the return flange 14 of the first side edge, the return flange 16 is out beyond the panel portion 11. In each instance the flat panel portion 11 terminates in a first crease line 19 which delineates an upwardly sloping portion 20, again terminating ~L054;~2S
in a second crease line 21 which delineates from the upwardly :~
sloping portion a short substantially vertical portion 22 the outer surfaces of which constitute abutment means for abutting one panel alongside another as shown in Fig. 1.
In the upwardly extending portion 15, the vertical portion 22 merges into a return horizontal portion 24 which in ~urn merges into a further upstanding vertical channel web 25, the vertical channel web 25 termina-ting along its upper edge in a horizontal channel web 26 which terminates in a depending vertical portion which is the return flange 16 and which has its lower edge inturned to function as an inturned tongue 28, the configuration thereby being a ~. -.
rectilinear channel, herein termed a "female" channel. The inturned tongue 28 is positioned away from the crease line lS between the vertical portion 22 and the return horizontal .. ~
portion 24 in such a way as to form a mouth designated 29, ~ .
which is inclined downwardly and outwardly.
The other side of the flat portion 11 extends as said with an upwardly extending portion 13 which includes an outwardly sloping portion 31 above the narrow vertical ~
portion 22, but the sloping portion 31 merges through a .
radius into the return flange 14 which is an inwardly and ~-downwardly sloping leg of an inverted V section channel 2 (herein termed a "male" channel), and which terminates at such a position above the flat panel portion that when the V-section male channel is forced or snap-fitted into the ~ ;
mouth of the female rectilinear channel of a similar section panel (or alternatively the female channel pressed downwardly .
over the male channel), firstly the free leg of the V is deflected inwardly and then it springs outwardly to engage -5- ~:

l~S~325 the lnturned tongue and the inner surface of the depending vertical portion of the rectilinear channel, as illustrated by the arrow in Figs. 2 and 3, or alternatively, is rotated into the rectilinear channel as illustrated by the arrow in Fig. 4.
It is Eound that this firm interengagement causes the assembly of the V-section male channel within the rectilinear female channel to become a relatively rigid assembly which ~ `
adds greatly to the stiffness of the decking panel as a whole, and reduces the need for closely spaced purlins for ; example. Furthermore, with this interengagement, the likeli-hood of a panel becoming disengaged under the weight of a `
person walking thereover is greatly reduced, this being a distinct advantage over previously known arrangements as for example, that described in the said Patent 261,846.
The V-section channel is the only channel having its mouth directed downwardly, but this is directed downwardly and outwardly towards the upper outer surface of the roof of which the panel forms part. Although spiders and other ~
insects may exist between the V-shaped panel and the inner `
walls of the rectilinear channel, their existence is o~ less consequence than in previously proposed configurations, ~`~
since it is not easy for them to enter a roof protected by panelling according to this invention, and the close abut-ment of the contiguous vertical portions limits possible ingress of insects into a building. The underside appearance is aesthetically pleasing, and in many instances a separate ceiling is not required.
