Abstract
Description
- 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 dips 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. Usually 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. When the sheets are interlocked the first formation of one sheet hooks on to the hook receiving part of an adjoining sheet and covers the valley and its fasteners. 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".
- In general, 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.
- We have found that there are conflicting factors between, on the one hand, increasing the strength and stiffness of the sheet and, on the other hand. ensuring adequate looking against suction forces under high wind conditions.
- USA 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. This sheeting system however is arranged so that the hook formation hooks under the hook receiving formation which results in a connection between sheets which is awkward to fit, requires the engaging sheet to be lifted at a large angle making it subject to excessive windage and when connected performs badly against suction forces under high wind conditions. This latter problem requires clamping bars to be provided.
- US-A 4 266 385 also shows a metal sheeting system in which a metal sheet is formed with a hook formation and a hook receiving formation as set out in the pre-characterising part of claim 1. This sheeting system does not have any latching provision.
- It is therefore an object of the present invention to provide an improved interlocking metal sheet which has good strength characteristics and improved interlocking formations.
- Accordingly the present invention is characterised in that 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 and further rotation is required before the formations can be unhooked.
- The rotation preferably occurs without significant distortion of the material of either sheet.
- Preferably, the further rotation is through at least 10°.
- The above and other aspects of the present invention will now be described with reference to the accompanying drawing in which:-
- Fig. 1 is a transverse section through a metal sheet,
- Fig. 2 is a view similar to Fig. 1 showing part of two sheets distorted by suction forces, and
- Fig. 3 is a similar section, to a larger scale, of an interconnection between two metal sheets.
- Referring to Fig. 1 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. Theformations 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 asloping part 10, a wall 11 approximately at right angles to the web 8, a flat 12 and downwardly and inwardly projectingparts curved part 15. As shown the outer end of thepart 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 apart 17 which, together with the wall 16b defines a hook receiving formation as will be described later. The lower end of the foldedpart 17 is formed as ahollow bead 18 and the rolled material of the sheet is then formed as aplatform 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 alip 23 at the same angle to the web 8 as thesloping part 10. Thelip 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. In Fig. 3 the same reference numerals have been used except that for the "adjoining" sheet suffixes "a" have been added to each reference numeral. - It will be assumed that 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 itshook 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 slopingpart 10 engages with the lip 23a and the wall 11, the flat 12, thepart 13 and thecurved part 15 respectively embrace the upper part of the side wall 21a, the platform 19a, the part 17a and thecurved part 15a. Sealing material (not shown) may be disposed in the recess 20a. The dimensions of theformations 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. - As mentioned above we have found that conflicting requirements exist in increasing the strength of the sheets without at the same time increasing the risk that suction forces under high wind conditions will tear off one of the sheets. When the sheets are mounted on spaced-apart purlins this reduces the number of edge fastenings that can be used.
- Although innately higher strength aluminum alloys than are usually employed can be used this does not, of itself, increase the strength of the sheets sufficiently. Increasing the height of the "raised seams" constituted by the
formations 3 and 6 does significantly increase the strength of the sheets and enables them to be unsupported across suitably spaced purlins. However such a change significantly alters the pattern of distortion of the "other" sheet 1a raised by suction forces on the web 8a resulting from wind flow across the outer surfaces 4 and 4a of the sheets. This change tends to make easier the lateral separation of the formations. - As shown in Fig. 2, 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 theformations 3 and 6. - With the present invention 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. As shown in Fig. 3 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. During the movement A to approximately C the wall 11 rides up the side wall 21a and retains its latching action. At the approximate position C the corner between the
sloping part 10 and the wall 11 rides over the corner between the side wall 21a and the platform 19a. As a result of the "latching fit" referred to above this transition occurs suddenly. In positions D and E the hook still remains engaged since the outer end of thepart 14 remains in engagement with a part of the bead 18a which extends parallel with the upper end of thesloping part 16. Once a sheet has been distorted to the extent represented in position E the strains to which it is subjected are extremely complex and not readily predictable. However it would be expected that position E represents the point at which the edge of the sheet 1 will move laterally and the formations will disengage. - In position C the
chain line 25 represents the angle between the edge of the web 8 and the line of the web 8a. The angle defined is G. - In position E 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:-
Height of theformations 3 and 6 a minimum of 10% (preferably 12.5%) of the total sheet width. This is to achieve a basic stiffness to the whole profile so as to allow it to support the imposed loads. - Length of the vertical wall 11 between 20% to 30% (preferably 24%) of the height of the
rib formation 3 and 6. - Centre of radius of tip of the hook receiving formation in the
range 10 to 20% (preferably 14%) below the top of the rib formation 6. - Distance of centre of radius of tip of hook receiving formation to vertical wall 11 when assembled in the range 3.75% to 6.25% (preferably 5%) of the total formation width.
- 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°). - By using a high strength aluminium alloy such as 3105 or 3004 in standard roofing sheet thicknesses and tempers and by increasing the height of the raised seams 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. By utilising 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.
- It will be understood that with the interlocking formations described above then should the sheet 1 be rotated through an angle significantly greater than the angle F (position E) the sheets will again interlock as the
part 14 extends upwardly behind the foldedpart 17. Depending upon the dimensions of these parts this re-engagement is likely to occur with an angle F of about 75°.
