Description
SYSTEM FOR INTERCONNECTING AND SECURING METAL SHEETS
This invention concerns a system for interconnecting first and second metal sheets and for securing them to an underlying structure, without the use of fasteners penetrating the sheets. In particular, the invention concerns a system for interconnecting first and second metal sheets in the form of roofing sheets for a building and for securing them to a roofing structure of a building.
It is known to provide systems for interconnecting metal roofing sheets and securing them to an underlying structure of a building. Such systems are often referred to as standing seam systems. In one known arrangement, such as described in GB-A-2 167 101, a number of spaced- apart retaining members or halters are arranged to support the edges of runs of metal roofing sheets. The edge of one sheet extends upwardly and curves around the top of the halter, while an overlapping edge of an adjoining sheet has a corresponding upstanding edge and a curved portion which fits over the curved portion of the first edge and can be mechanically deformed by a specially designed machine, by a process known as "zipping-up", to lock both overlapping edges to the top of the halter. This arrangement has several advantages in that it resists uplift of the resulting roof due to wind and can be manufactured in almost unlimited lengths.
However, it is rather expensive because of the cost of the halters.
In another arrangement, described in EP-A-0 342 044, no such retaining halters are provided. One edge of a metal roofing sheet is secured at intervals along its length to an underlying roof support structure, such as purlins, and an edge of the next sheet clips over the edge of the first sheet and rolls down into the required position.
This has the advantage of simplicity, but has a number of disadvantages. These include the need to secure the edges with bolts or other fasteners through elongate holes provided in the longitudinal direction of the roofing sheet in order to allow for expansion and contraction, and to provide covers over the elongate holes and beneath the heads of the fasteners to allow relative movement. There are also minor problems with uplift in strong winds. Furthermore, the sheets cannot be readily curved along their length and they have to be formed off-site, which restricts the lengths available.
It is an object of the present invention to overcome or minimise one or more of the above problems.
According to the present invention there is provided a system for interconnecting first and second metal sheets and for providing securement thereof to an underlying structure, the system comprising: the first metal sheet having an elongate edge thereof profiled to provide first, second and third integral portions, the first portion extending in upstanding manner from the first metal sheet to the second portion, the second portion being of substantially tubular form, the third portion being adapted to extend from the second portion towards the underlying structure and being adapted to be secured by clip means to the underlying structure; the second metal sheet having an elongate edge thereof profiled to provide first and second integral regions, the first region extending in upstanding manner from the second metal sheet to the second region, the second region being of open arcuate form adapted to be engaged in an overlying lacking manner with the substantially tubular second portion of the profiled elongate edge of the first metal sheet.
The engaged first and second metal sheets may be substantially coplanar.
The second region of the profiled elongate edge of the second metal sheet may be adapted to be engaged in an overlying locking manner with the substantially tubular second portion of the profiled elongate edge of the first metal sheet by means of snap-fit engagement therebetween and optional subsequent mechanical forming of the open arcuate-formed second region of the profiled elongate edge of the second metal sheet whereby it is conformed around the substantially tubular second portion of the profiled elongate edge of the first metal sheet.
The third portion of the profiled elongate edge of the first metal sheet may have a lower edge arranged substantially coplanar with the first metal sheet. Such lower edge may be profiled to provide one or more attachment regions for engagement by the clip means.
The one or more attachment regions may be of substantially U-shaped crosssection.
The one or more attachment regions of substantially U- shaped cross-section may be provided by a channel extending along at least part of the lower edge of the third portion of the profiled elongate edge of the first metal sheet.
The clip means may comprise one or more clips, such as of metal, having a first region adapted to be secured to the underlying structure and a second region adapted to engage, such as in complementary manner, the one or more attachment regions provided by the profiled lower edge of the third portion of the profiled elongate edge of the first metal sheet. The second region of the or each clip may be of substantially inverted Ushaped cross-section.
The first region of the or each clip may be provided with one or more apertures therethrough for receiving one or more fixing means, such as one or more threaded fasteners, nails or bolts, for securing the or each clip to the underlying structure.
A plurality of clips may be provided, spaced apart along the profiled lower edge of the third portion of the profiled elongate edge of the first metal sheet.
The clip means may be formed from one or more appropriately profiled metal strips.
The first portion extending in upstanding manner from the first metal sheet and/or the first region extending in upstanding manner from the second metal sheet may comprise a sloping part and a substantially vertical part. Such sloping part may be such as to provide clearance for the clip means.
The first metal sheet may have an opposite elongate edge profiled substantially corresponding to the profiled elongate edge of the second metal sheet.
The second metal sheet may have an opposite elongate edge profiled substantially corresponding to the profiled elongate edge of the first metal sheet.
The first and/or second metal sheet(s) may be provided with one or more elongate ribs or corrugations to improve mechanical rigidity thereof.
The first and/or second metal sheet(s) may be provided with a plurality of elongate micro-ridges, such as for providing resistance to mechanical damage and/or to assist curving of the sheet or sheets when required.
The first and/or second metal sheet(s) may comprise aluminium or steel.
The first and second metal sheets may comprise roofing sheets for a building. The underlying structure may comprise a roof supporting structure of a building, such as comprising purlins.
For a better understanding of the present invention and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which: Figure 1 shows first and second metal sheets to be interconnected and secured to an underlying structure; Figure 2 is a cross-sectional view of an embodiment of a system according to the present invention for interconnecting the first and second metal sheets of Figure 1 and for providing securement thereof to the underlying structure; Figure 3 is a cross-sectional view of the first and second metal sheets of Figure 1 after interconnection and securement to the underlying structure by the system of Figure 2; and Figure 4 shows clip means securing the interconnected first and second metal sheets to the underlying structure in the system of Figures 2 and 3.
Referring to Figures 1, 2 and 3, a system is provided for interconnecting a first metal sheet 2 and a second metal sheet 4 and securing them to an underlying structure 6.
The first 2 and second 4 metal sheets suitably comprise roofing sheets for a building, in which case the underlying structure 6 comprises a roof supporting structure of the building and may comprise purlins. The first and second metal sheets 2, 4 suitably comprise aluminium or steel.
The first metal sheet 2 has an elongate edge 8 thereof profiled to provide a first portion 10, a second portion 12 and a third portion 14, the portions 10, 12 and 14 being integral with one another and with the first metal sheet 2 and formed by appropriate mechanical bending and profiling of the elongate edge 8 of the first metal sheet 2. The first portion 10 extends in upstanding manner from the first metal sheet 2 to the second portion 12 and comprises a sloping part 16 and a substantially vertical part 18. The second portion 12 is of substantially tubular form. The third portion 14 is adapted to extend from the second portion 12 downwardly towards the underlying structure 6 and is adapted to be secured by a plurality of clips 20 to the underlying structure 6.
The second metal sheet 4 has an elongate edge 22 thereof profiled to provide a first region 24 and a second region 26. The regions 24 and 26 are integral with each other - 10 - and with the second metal sheet 4 and are formed by appropriate mechanical bending and profiling of the elongate edge 22 of the second metal sheet 4. The first region 24 extends in upstanding manner from the second metal sheet 4 and comprises a sloping part 28 and a substantially vertical part 30.
