Definitions

  • This invention relates to metal sheeting.
  • Metal profiled sheets are frequently used as roof panels and for other building cladding purposes. It is well known to provide a metal sheet which is pre-formed with integral ribbing so that it may readily be interlocked at adjoining edges with a similar sheet and which may be fastened to a support without the fastening means being exposed to the environment or being on the visible side of the sheet. These products may include separate fixing clips and involve on site roll forming to close the interlocking seams. All such products are usually referred to as "raised seam cladding". Many examples of such profiled sheets are known and they are frequently roll-formed from an aluminium alloy as well as other metallic materials.
  • each sheet has a first upstanding hook formation along one edge and a second upstanding formation along an opposite edge of the sheet with a hook receiving part and a valley in the plane of the sheet through which fasteners can be passed.
  • first formation of one sheet hooks on to the hook receiving part of an adjoining sheet and covers the valley and its fasteners.
  • the sheets From their outer surfaces the sheets then present a generally flat appearance having spaced apart upstanding ribs with no fasteners visible. These ribs are usually referred to as "raised seam”.
  • the sheets when used as roof panels, the sheets need to be fully supported on a pre-prepared flat surface and are not strong enough to span any worthwhile distance between supporting purlins. It is however clearly desirable to provide sheets that can be supported at intervals, as between spaced apart purlins, and it is further desirable that the sheet should be wider so that the spacing between the raised seams is increased. In addition the sheets should be strong enough to support snow loads, wind loads both in pressure and suction and so that, for example, operatives can walk on them.
  • US-A 4,423,581 shows a metal sheeting system in which a metal sheet is formed with a central web extending laterally towards lateral edges having an outer surface facing in an outer direction, a hook formation along one said lateral edge projecting in the outer direction and facing away from the central web, a hook receiving formation along an opposed said lateral edge projecting in the outer direction and facing toward the central web, the hook receiving formation having a valley portion extending laterally toward the opposed lateral edge away from a hook receiving portion of the receiving formation, the arrangement being such that the sheet can be fastened directly to a support without the interposition of separate clips.
  • the present invention is characterised in that the hook formation of one sheet can hook over the upstanding hook receiving formation of an adjoining sheet and cover its valley wherein latching means act between the formations to latch them together subsequent to their being hooked together and wherein after such latching said one sheet can be rotated about the hook receiving formation of the other sheet through at least 25° to unlatch the sheet and before the formations can be unhooked.
  • the rotation preferably occurs without significant distortion of the material of either sheet.
  • the latching action ceases to function, and further rotation through at least 10° is required before the formations can be disengaged.
  • a roll-formed aluminium alloy sheet 1 has along one side edge 2 a first, hook, formation indicated generally at 3 which is upstanding from the outer surface 4 of the sheet. At its other side edge 5 the sheet has a second, hook receiving, formation indicated generally at 6 and a valley 7. The formations 3 and 6 are separated by a web 8 which is coplanar with the floor 9 of the valley 7. A number of stiffening ribs 8b may be formed in the sheet.
  • the hook formation 3 comprises a sloping part 10, a wall 11 approximately at right angles to the web 8, a flat 12 and downwardly and inwardly projecting parts 13 and 14 constituting a hook having a curved part 15. As shown the outer end of the part 14 is curved to be approximately parallel with the wall 11 and to allow run-out on the edge of the sheet material on roll forming.
  • the hook receiving formation 6 comprises a sloping part 16 the upper end 16b of which is approximately at right angles to the web 8 and is then folded at a part 17 which, together with the wall 16b defines a hook receiving formation as will be described later.
  • the lower end of the folded part 17 is formed as a hollow bead 18 and the rolled material of the sheet is then formed as a platform 19 with a recess 20, a side wall 21 approximately at right angles to the web 8 leading to the valley 7, the floor 9 of which has an upwardly turned part 22 and a lip 23 at the same angle to the web 8 as the sloping part 10.
  • the lip 23 allows run out of the edge of the sheet material on roll forming.
  • Fig. 3 shows how the hook formation 3 engages over the hook receiving part 6 of an adjoining sheet.
  • the same reference numerals have been used except that for the "adjoining" sheet suffixes "a" have been added to each reference numeral.
  • the sheet 1a is already mounted on suitably spaced-apart purlins (not shown) and secured thereto through the valley floor 9a.
  • the fixings used can be conventional and may be arranged to accommodate longitudinal expansion of the sheet 1a.
  • the sheet 1 is then held with its web 8 approximately vertically and its hook formation 3 engaged around the bead 18a.
  • the sheet 1 is then pivoted to the position shown in cross-hatched lines in Fig. 3 and secured to the purlins. In this position the sloping part 10 engages with the lip 23a and the wall 11, the flat 12, the part 13 and the curved part 15 respectively embrace the upper part of the side wall 21a, the platform 19a, the part 17a and the curved part 15a. Sealing material (not shown) may be disposed in the recess 20a.
  • the dimensions of the formations 3 and 6 are such that the upper part of the formation 2 is a "latching fit" over the upper part of the formation 6.
  • wind flow across the outer surfaces 4 and 4a can cause high suction forces to be applied to the webs of the sheets and lift these webs so that their formations 3 and 6 distort and move laterally to disengage the formations 3 and 6.
  • the close, "latching fit” engagement between the upper parts of the formations ensures that the wall 11 constitutes latching means for the hook by its close fit against the upper part of the side wall 21a.
  • the edge of the sheet 1 can rotate about the bead 18a through successive positions indicated at A, B, C and D before reaching the position E shown as a solid line.
  • the wall 11 rides up the side wall 21 a and retains its latching action.
  • the corner between the sloping part 10 and the wall 11 rides over the corner between the side wall 21 a and the platform 19a.
  • the chain line 24 represents the angle between the edge of the web 8 and the line of the web 8a.
  • the angle defined is F.
  • the precise angle F reached for position E is determined by the detailed dimensions of the upper parts of the formations 3 and 6, the width of the web 8 and the thickness of the sheet. We have found the following criteria achieve good results:-
  • Length of the vertical wall 11 between 20% to 30% (preferably 24%) of the height of the rib formation 3 and 6.
  • Sheet thickness lies in the range of 0.15% to 0.25% of total formation width.
  • the angle G is in the range 25° to 30° (preferably 28°).
  • the angle F is in the range 10° to 35° greater than angle G (preferably 30°).
  • the basic strength of sheets 500 mm wide can be increased sufficiently to enable the sheets to span purlins with spacings in excess of 2.0 m and still readily support snow and wind loads both in pressure and suction and carry the weight of an operative between the purlins.
  • the latching feature of the present invention the disadvantages of increasing the height of the seams can be obviated and increased protection given against suction induced by wind force.
