Definitions
- the present invention relates generally to a constructional panel and a method of forming a constructional panel .
- the invention relates particularly, though not exclusively, to metal roof panels and their methods of fabrication.
- a constructional panel comprising: at least a pair of substantially parallel and spaced apart rib formations; and a pan disposed between said pair of rib formations, the pan including a plurality of spaced apart microflutes extending transversely relative to said rib formations.
- a method of forming a constructional panel comprising the steps of : forming at least a pair of substantially parallel and spaced apart rib formations in sheet wherein a pan is formed between the pair of rib formations; and forming a plurality of microflutes in at least part of the pan, the microflutes being spaced apart and extending transversely relative to said rib formations.
- the microflutes are in the form of substantially parallel and space apart groove and ridge formations in which the depth from ridge peak to groove root is in the range of 0.05mm to 5mm and the pitch from ridge peak to adjacent ridge peak is in the ranges 10mm to 50mm. More preferably the depth is 0.1mm and the pitch is 10mm.
- the groove and ridge formations are of essentially constant depth and pitch.
- the groove formations are of substantially V- shaped cross-section and the ridge formations are of substantially inverted V-shaped cross-section. More preferably the ridge and groove formations have rounded peaks and nadirs respectively.
- the ratio of the depth to the pitch of each of the microflutes is less than approximately 1:15.
- the constructional panel is a metal constructional panel . More preferably the panel is elongate and the rib formations extend longitudinally of the panel .
- the step of forming the transverse microflutes in the pan involves roll forming the pan intermediate the pair of longitudinal rib formations. More preferably the transverse microflutes are cold roll formed in the pan.
- the plurality of transverse microflutes are each in cross-sectional profile substantially identical to one another and aligned parallel to one another.
- the transverse ribs in cross-section together define a zig-zag profile. More preferably the ribs are in the form of repeating corrugations arranged in a common plane of the pan.
- the pan at its opposing longitudinal edge portions includes a generally flat strip. More preferably the flat strip extends alongside an adjacent of the rib formations and generally at a level of grooves or ridges formed by the transverse microflutes. Generally the pair of flat strips occupy less than about 15% of the pan.
- the pair of rib formations are each in cross- section generally trapezium-shaped. More preferably the constructional panel includes a plurality of the pair of rib formations being arranged parallel and equally spaced from one -another, the pan being one of a plurality of pans each located between a pair of adjacent of said longitudinal rib formations.
- the constructional panel at its opposing longitudinal edge margins includes respective edge rib formations being adapted to interlock with a corresponding edge rib formation of an adjacent constructional panel. More preferably the interlocking longitudinal edge rib formations are together in cross-section shaped substantially identical to the longitudinal rib formations .
- Figure 1 is a perspective view of part of a constructional panel according to an embodiment of the invention
- Figure 2 is and end elevational view of the panel of Figure 1 ;
- Figures 3 and 4 are plan views from below and above, respectively, of the panel of Figure 1;
- Figure 5 is a cross-sectional view taken through line A-A of Figure 4 and depicting the transverse stiffening ribs of the panel of Figure 1 in enlarged and exaggerated detail;
- Figure 6 is a graph load verses deflection for the panel of Figure 1 together with comparative plots for other panels.
- Figure 7 is a schematic illustration of part of the panel of Figure 1 when deflected under pressure.
- FIG. 1 to 4 there is a constructional panel in the form of a metal roof panel 10.
- the roof panel 10 is suitable for cladding a roof although it should be appreciated that it extends to other applications, for- example, wall cladding.
- the metal roof panel 10 is elongate and in this example comprises four longitudinally extending and equally spaced apart rib formations 12/14/16/18. Adjacent pairs of the longitudinal rib formations such as 12 and 14 are interconnected by a pan 20.
- the intermediate longitudinal rib formations 14 and 16 of this embodiment are in cross- section generally trapezium shaped.
- the longitudinal ribs 12 and 18 located at opposing longitudinal edge margins of the roof panel 10 are designed to interlock with a corresponding edge rib of an adjacent roof panel (not shown) .
- the interlocking longitudinal edge ribs are together in cross-section shaped substantially identical to one of the intermediate longitudinal rib formations such as 14.
- the longitudinal rib formations 12/14/16/18 are similar in construction to those of the applicant's roof cladding commercially available in Australia under the trade mark KLIP-LOK.
- the pans such as 20 each include a plurality of transversely extending and spaced, apart microflutes such as 22.
- the microflutes 22 of this example are in the form of substantially parallel and spaced apart groove and ridge formations such as 23 and 25, respectively.
- the depth from ridge peak to groove root is about 0.5mm and the pitch from ridge peak to adjacent ridge peak is around 10mm.
- the groove and ridge formations are of a substantially V-shaped ° and inverted V-shaped- _- cross-section, respectively.
- the groove and ridge formations 23 and 25 have rounded peaks and nadirs, respectively.
- the microflutes such as 22 of this embodiment provide stiffening to the otherwise unstable pan such as 20. This is an advantage where for example the roof panel 10 is fabricated from relatively thin gauge strip steel, for example 0.42, 0.48 or 0.60 mm gauge strip steel. Thus, the width of the pan 20 or distance between longitudinal rib formations such as 12 and 14 can be increased whilst the rigidity of the pan 20 is maintained.
- the transverse microflutes such as 22 should be of a reduced height to width ratio in order to minimise the retention of water, soil or foliage.
- the microflutes 22 are also designed for aesthetic reasons to provide an attractive and "natural" appearance .
- Figure 6 is a graph of load versus deflection for the metal roof panel 10 of the preceding embodiments.
- the load is in Newtons and intended to be representative of typical uplift loads on roof cladding panels as a result of wind forces.
- the deflection is in millimetres and is the maximum deflection of the pan such as 20 from a flat plain under the various uplifting forces.
- the various plots of Figure 6 include load/deflection tests for:
- plot (c) relates to the described embodiment of the present invention whereas plots (a) , (b) and (d) relate to conventional or comparative constructional panels.
- the preferred embodiment including the transverse microflutes provides increased loadings for the same deflection as the conventional or comparative examples.
- the icrofluted panel requires 70 Newtons (N) to deflect 40mm whereas the conventional panels of plots (a) and (b) required about 60 N. This represents an increase in stiffness of around 15%.
- FIG 7 is a schematic and exaggerated illustration of a constructional panel such as the metal roofing panel 10 of the preceding embodiment when mounted to a roof structure or like via concealed fixing clips such as 26 and 28.
- the solid line of the pan 20 of the panel 10 is in its unloaded condition whereas the broken line represents the pan 20 when deflected under wind pressure. It will be apparent that the deflected pan 20 in this condition has dislodged from the concealed clips 26 and 28.
- the load required to dislodge a constructional panel including the transverse microflutes of the present invention is significantly higher than that of -.conventional or comparative roof panels as illustrated and " explained in- the context of the graph of Figure 6. Therefore, the metal roof panel such as 10 including the transverse microflutes is less susceptible to dislodgment from the concealed clips or other mounting means.
- the pan such as 20 of the roof panel 10 shown in Figure 1 includes a generally flat strip such as 24 formed at each of its opposing longitudinal edge portions.
- the flat strip such as 24 extends alongside the adjacent longitudinal strengthening rib formation 12 and is generally at a level of the grooves formed by the transverse microflutes 22.
- the flat strips such as 24 provide run-off for any water or other matter which may have collected in the grooves or troughs of the transverse ribs 22.
- the flat strips such as 24 occupy about 10% of the pan 20.
- the dimensions of the constructional panel and for example the height of the longitudinal rib formations relative to the width of the pan may vary but still remain within the scope of the present invention.
- the ratio of the height of the rib formations such as 12 and 14 to the width of the intermediate pan 20 is about 1:4. This corresponds to a longitudinal rib height of about 43 mm and a pan width of about 175 mm.
- transversely extending microflutes are roll formed in a pan defined between adjacent pairs of rib formations in the roof panel.
- the longitudinal rib formations and microflutes such as 12 and 22, respectively will generally be cold roll formed in " strip steel.
- the longitudinal rib formations such as 14 and transverse microflutes 22 are formed sequentially.
- the strip steel is generally provided with a corrosion resistant coating.
- the constructional panel may include longitudinal rib formations at its opposing edge margins only.
- the transverse microflutes may vary in cross- sectional profile and unlike the described embodiment extend the full width of the pan.
- the constructional panel may be partly or entirely constructed of a plastics material . All such variations and modifications are to be considered within the scope of the present invention the nature of which is to be determined from the foregoing description.
