Definitions

  • the present invention relates generally to wall cladding and roofing systems for use in building construction.
  • the invention finds application in the construction of domestic dwellings as well as buildings for commercial and industrial uses.
  • the walls and roof of the structure are commonly formed by first erecting a structural timber frame.
  • the wall frame is subsequently lined internally with a sheet material such as plasterboard, and externally with weatherboards or for instance brick veneer.
  • This provides a structure that is relatively solid and weather proof.
  • the laying of bricks is labour intensive and the bricks themselves are relatively expensive.
  • Timber is also becoming increasingly costly and the fasteners used to fix the timber or substitutes therefore to the structural frame either remain exposed to environmental conditions and so are prone to corrosion, or need to be painted for protection against corrosion.
  • roofs of building structures to be formed from tiles or galvanised sheets. Tiled roofs are expensive and the laying of the tiles is again labour intensive and time consuming. In addition, the tiles themselves are heavy. The same applies to roofs formed from galvanised iron sheets which need to be secured to the underlying roof frame by relatively closely spaced fasteners to achieve adequate securing of the sheets in position.
  • a system of cladding involving the use of panels that terminate along opposite side regions thereof in downwardly directed hooks for insertion into spaced apart grooves of an underlying mount to secure the panels in position.
  • a first panel is secured to the mount by pressing the hooks of the panel into the appropriate grooves of the mount.
  • the leading hook of a second panel is then overlayed above the trailing hook of the first panel prior to being pressed into the mount so that the two hook formations are nested one within the other.
  • the trailing hook formation of the second panel is also pressed into a further groove of the underlying mount.
  • the cladding is achieved by repeating the process to progressively lay further panels along the mount.
  • the resultant cladding is potentially prone to seepage of water between the downwardly directed hooks of consecutive panels increasing the risk of corrosion of the panels over time.
  • a cladding system in described that involves the partial overlapping of panels, the panels having a pair of spaced apart flanges extending along opposite side regions of each panel respectively.
  • Each panel further incorporates a hook shaped depression in the intervening region of the panel between the flanges of the panel, the hook being pressed into a groove of a mount to secure the panel to the mount.
  • the mount is adapted to be secured a frame of a building structure.
  • the formation of the cladding is achieved by arranging the panels in a side by side relationship such that one of the flanges of one sheet rests on the other flange of a consecutive sheet.
  • a cladding sheet comprising an elongate, generally planar panel section having longitudinal edge flanges along opposed side edges, and a longitudinally extending hook formation for engagement with cladding mounting means to secure the sheet thereto, the hook formation being formed on one flange which depends away from a generally lower or inner surface of the panel section, and the flange being formed to overlie and thereby secure an opposed edge of a similar adjacent sheet.
  • a wall or roofing cladding sheet comprising a generally planar elongated panel section the longitudinal side edges of which are formed to engage and interlock with corresponding side edges of similar adjacent sheets; a first of said side edges being formed with a first upstanding flange having a reversely turned edge section defining a channel, and a downwardly extending second flange having a hook formation for engagement with cladding mounting means to secure the sheet thereto, a second of said side edges being formed with a third flange upstanding from the panel section and adapted to engage within the channel of a similar, adjacent sheet.
  • the downwardly extending, second flange having the hook formation will be integrally formed with the first flange and will extend down from the channel spaced inwardly from the reversely turned edge section, which forms an outer wall of the channel.
  • the hook formation extends inwardly from the second flange, in the direction of the panel section.
  • the third flange is also formed with a downwardly extending second hook formation which extends inwardly and is adapted to engage with the cladding mounting means.
  • both side edges of the panel section are positively connected with the cladding mounting means.
  • the mounting means comprises a batten or purlin formed with a plurality of longitudinally spaced, laterally extending slots or grooves.
  • the slots or grooves are undercut so that the hook formations engage beneath the undercut to securely lock the cladding sheet to the batten or purlin.
  • the batten or purlin is formed of metal, such as galvanised steel or the like, and is adapted to be secured by the use of nails, screws or the like to a building framework onto which the cladding is to be mounted.
  • the cladding sheet of the invention may be used as a roofing panel, for use in forming a flat or pitched roof, or as a wall cladding panel.
  • a cladding system comprising an assembly of cladding sheets as previously described and mounting means locking the sheets to a structure, said mounting means comprising a plurality of generally parallel battens or purlins each having a plurality of transversely extending, longitudinally spaced receptors receiving and interlocking with the hook formations of the assembled sheets.
  • the battens or purlins are roll-formed from sheet metal, such as aluminium or sheet steel, and the receptors comprise slots or grooves formed in the battens or purlins in such a way that the downwardly extending hook formations of the individual cladding sheets engage within and are interlocked by the slots or grooves.
  • the slots or grooves have a shape in the form of an inverted T or a keyhole shape whereby the hook formation is resiliently deformed during movement of the hook formation into a slot with recovery of the resilient deformation occurring when the hook formation is at the lower, enlarged end of the slot to thereby lock the hook formation and its associated flange to the batten or purlin.
  • cladding of the invention therefore provides the basis for a rapid and convenient building system for forming the roof or exterior wall surface of a house, shed or other building structure. More particularly, a wall or roof can be rapidly constructed by firstly securing mounting means such as battens or purlins to the frame of the building structure prior to fixing an initial cladding sheet of the invention to the mounting means and progressively laying subsequent cladding sheets, one after the other. As such, the time involved in the construction of the wall or roof can be significantly minimised.
  • mounting means such as battens or purlins
  • the channel formed by the reversely turned first upstanding flange may have a substantial depth commensurate with the height of the third flange which is adapted to engage within a channel of a similar, adjacent sheet, the likelihood of water entering a roof cavity by flowing around the third flange within the channel is greatly reduced thereby ensuring that the roof or wall cladding is weatherproof.
  • the hook formation is located on the second flange which extends downwardly from the channel, the only exposed edge of the sheet being the channel defining outer wall of the first flange, that exposed edge is securely locked by the hook formation to the mounting means thereby reducing the possibility that a cladding sheet can be peeled from a roof structure by wind or the like.
  • metal battens or purlins are formed with a plurality of spaced tangs adapted to receive and support wire mesh extending between the battens and used to support insulating material which may be required under the cladding sheets.
  • Such tangs enable a supporting mesh to be quickly and readily located in position without the use of additional fasteners or other insulation supports.

  • Fig 2 is an end view of a mounting batten for use with the cladding sheet of Fig l
  • Fig 3 is an end view of two cladding sheets of Fig 1 interengaged with a mounting batten of Fig 2;

  • Figs 12 and 13 are perspective views of purlins in accordance with the invention.
  • the cladding sheet 10 shown in Fig 1 comprises a pair of spaced flanges 12 and 14 extending along opposite side edges of the cladding sheet 10 and being spaced apart by an intermediate panel section 16.
  • the flange 12 extends upwardly from the panel section 16 and has a reversely turned portion 20 which defines a channel 24 having its mouth opening downwardly.
  • a further flange 18 extends downwardly from the first flange 12 and is provided with a hook formation 26 along its lower edge.
  • the second, downwardly extending flange 18 defines an inner wall 22 of the channel 24 which is substantially parallel with the outer wall of the channel 24 formed by the first flange 12.
  • the channel 24 is thus defined by a double wall providing substantial strength to the edge formation of the cladding sheet 10.
  • the hook formation 26 extends inwardly towards the inner face 28 of the cladding sheet 10.
  • the third flange 14 extends upwardly from the opposite side edge of the cladding sheet 10 to an apex 32 where the flange 14 is folded back on itself to define an outer wall 34.
  • Fig 2 shows a mounting batten 36 in accordance with one embodiment of the invention.
  • the batten 36 includes a pair of generally parallel, longitudinally extending flanges 38 having downwardly extending legs 54 which are slightly splayed and which terminate in an outwardly directed foot 56 by which the batten 36 is secured to an underlying building frame structure (not shown).
  • the battens 36 will be secured by nails, screws or the like to a timber or metal sub-frame structure.
  • the batten 36 is provided with a plurality of transversely extending, longitudinally spaced slots 40 in each of the flanges 38.
  • the slots 40 in opposed flanges 38 are aligned to receive the downwardly extending flange 18 of the cladding sheet 10.
  • Each slot 40 has a narrow entry 42 opening into an enlarged lower slot portion 44 defining an undercut shoulder 46.
  • the upstanding flange 14 of a first cladding sheet 10 is engaged within the channel 24 of a second cladding sheet 10 and the downwardly extending flange 18 of the second cladding sheet 10 engages within the slot 40 of the batten 36.
  • the hook formation 26 is resiliently deformed to pass through the narrow slot opening 42 until it reaches the enlarged slot portion 44 where the hook formation 26 engages behind the undercut shoulder 46 to thereby lock the flange 18 into the slot 40 thereby securing the second covering sheet 10 to the batten 36 which, in turn, locks the third flange 14 of the first covering sheet 10 to the batten 36.
  • an essentially continuous cladding cover may be provided for a roof, wall structure or the like.
  • a cladding sheet 10 of a second embodiment is illustrated in which the outer wall 34 of the third flange 14 is provided with an inwardly directed hook formation 35.
  • the outer wall 34 is extended into a downwardly extending flange of a length which enables the hook formation 35 to engage within a slot 40.
  • the slot 40 of a batten 36 is formed in the shape of an inverted T or in a keyhole shape thereby defining two undercut shoulders against which can be engaged the hook formations 26 and 35 of the downwardly extending flanges 18 and 34.
  • the panel section 16 of the cladding sheet 10 is formed with upwardly diverging panel regions 48a and 48b immediately adjacent the upwardly extending flanges 12 and 14.
  • the panel regions 48a and 48b generate an upwardly biasing force when the flanges 18 and 34 are pressed downwardly into the appropriate slots 40 to thereby ensure that the hook formations 26 and 35 are positively engaged against the undercut shoulders 46 in the slots 40.
  • the natural resilience of the cladding sheet 10 provides the necessary biasing force.
  • the downwardly extending flanges 18 and 34 shown in Figs 5 and 6 are formed so that a first, upper flange part is slightly angled away from the panel section 16 and a lower flange part is slightly angled back towards the panel section 16.
  • the bend in the downwardly extending flanges 18 and 34 ensures that the flanges interengage, in a resilient manner, as shown particularly in Fig 6, when the hook formations 26 and 35 are engaged within the slot 40 of the batten 36.
  • This arrangement ensures that the hook formations 26 and 35 are biased into positive engagement with the undercut shoulders 46.
  • Fig 7 illustrates a modified hook formation 35 in which the end of the hook is turned back on itself to form a shoulder, the upper surface of which closely engages the undercut shoulder 46 of the slot 40. This provides a larger engagement surface reducing the likelihood of deformation of the hook portion 35 under load.
  • a roof assembly 52 formed with the use a modified form of cladding of sheet 10 is illustrated in Fig 8. Although only a single batten 36 is shown, it will be appreciated that, in practice, a number of spaced battens 36 extending substantially parallel with respect to one another will be utilised such that the cladding sheets 10 lay transversely across and are secured thereto.
  • the cladding sheet 10 has a centrally located, longitudinally extending upstanding channel 58.
  • the channel 58 is formed with an inwardly turned ledge 66 defining an internal shoulder.
  • a fixing strip 60 having a structure similar to the downwardly extending flange 34, is engaged within slots 40 of battens 36 and has an upper hook 64 which engages behind the ledge 66 within the channel 58.

  • cladding sheets 10 may be made of any suitable width with upstanding channels 58 spaced across the width of the cladding sheets 10 a distance equal to the distance between slots 40 along battens 36, or multiplies thereof.
  • Fig 8 also illustrates an end fixing strip 50 which has a shape similar to that of an upstanding flange 12, include a channel ' 24, and which is adapted to engage over and lock the upstanding flange 14 of an end panel 16 on a roof structure 52.
  • Fig 9 illustrates in a partially exploded view a roof assembly having end covers 68a and 68b which are adapted to be engaged with the battens 36 to prevent wind and water entering under the roof structure and into a roof cavity of a building on which the roof is assembled.
  • the end cover 68a is provided with an upstanding flange 12a similar in construction to the flange 12 of a cladding sheet 10.
