Definitions
- This invention relates to roofing systems, and in particular to roofing systems comprising at least a first roofing element and a second roofing element, each roofing element having a first longitudinal edge and a second longitudinal edge opposite the first longitudinal edge, the first longitudinal edge having first coupling means configured to engage with a fixed structure so as to fasten the first longitudinal edge to the fixed structure, and the second longitudinal edge having second coupling means configured to engage with the first coupling means of the first longitudinal edge of a like roofing element so as to fasten the second longitudinal edge to the first longitudinal edge.
- Typical roof constructions have three main structural components: 1) wall plates, 2) rafters and 3) battens where a pair of parallel, horizontally extending load-bearing beam-like wall plates supporting a plurality of elongate rafters extending transversally to the wall plates and thus defining the fundamental shape of the roof which can be flat, sloping, curved, A-shaped or other.
- the rafters support a plurality of roofing battens or laths which provide fixing points for roofing materials such as shingles or tiles.
- the roofing systems FASTLOCK ® and FASTLOCK UNI ® produced and sold by the applicant use such roof construction and is disclosed in Danish design application MA 1999 00615 and Danish design registration MR 2000 00189 .
- the invention provides a roofing system comprising a plurality of elongate supporting rafters, each supporting element having a top surface and two opposed side surfaces, and a plurality of elongate top roofing elements, each top roofing element having a first longitudinal edge portion with first engagement means capable of directly or indirectly engaging the two opposed side surfaces of one of the supporting rafters, and a second longitudinal edge portion with second engagement means capable of engaging the first longitudinal edge of another one of the top roofing elements.
- Such roofing system is suitable for use with FASTLOCK ® and FASTLOCK UNI ® top roofing elements and have only two main structural components and thus offering a simpler construction which is less labour consuming to mount. In addition, the final result has a light and attractive appearance.
- the invention also provides a tool for use when assembling a plurality of two or more top roofing elements.
- FIG. 1-3 is shown a roofing system with an elongate rafter 10 preferably with a rectangular cross section and having a top surface and two opposed side surfaces with an optional longitudinal groove 11 in each side surface.
- FIGS 1-3 also show two identical FASTLOCK ® or FASTLOCK UNI ® elongate top roofing elements, a first roofing element 20a and a second roofing element 20b, preferably made of a weatherproof and elastic material e.g. by extrusion.
- Each top roofing element 20a, 20b has a first longitudinal curved edge portion 21 forming a longitudinally extending bead with a neck portion where the concave side of the curved edge portion 21 defines a downwardly open longitudinal channel with a pair of inwardly protruding ridges 22.
- the first longitudinal curved edge portion 21 is mounted over the top surface of the elongate rafter 10 so that the elongate rafter 10 is received in the channel defined by the first curved edge portion 21, and each of the ridges 22 engages directly with one of the opposed side surfaces of the elongate rafter 10 and possibly with the grooves 11.
- the first top roofing element 20a is retained in place on the rafter 10 by friction due to the dimensions and elastic properties of the top roofing element 20, and possibly also by positive engagement of the ridges 22 and the optional grooves 11.
- Each top roofing element 20a, 20b also has a second longitudinal curved edge portion 23 forming a longitudinally extending bead opposite the first longitudinal edge portion 21 where the concave side of the curved edge portion 23 defines a downwardly open longitudinal channel
- figures 1-3 show that the second longitudinal curved edge portion 23 of one top roofing element 20 is mounted over the first longitudinal curved edge portion 21 of another top roofing element 20 where the first longitudinal curved edge portion 21 is received in the channel defined by the second curved edge portion 23, and the second longitudinal curved edge portion 23 snaps behind the first longitudinal curved edge portion 21 into engagement with the neck portion of the first longitudinal edge portion 21, whereby the second roofing element 20b is retained by positive engagement.
- the dimensions and elastic properties of the second longitudinal edge portion 21 further add to retaining the first top roofing element 20a in place on the rafter 10 so that both top roofing elements 20a and 20b are secured against being torn off e.g. by strong winds.
- FIGS 4-7 is shown a roofing system with an elongate rafter 12 preferably with a rectangular cross section and having a top surface and two opposed side surfaces.
- the elongate has a width (the shorter of the two dimensions shown) which is smaller than the width of the rafter 10 in figures 1-3 .
- Figures 4 and 5-7 also show the same first and second FASTLOCK ® or FASTLOCK UNI ® elongate top roofing elements 20a and 20b as in figures 1-3 . Since the rafter 12 is narrower than the rafter 10 in figures 1-3 then the first longitudinal curved edge portion 21 of the top roofing element 20a cannot engage directly with the rafter 12 with sufficient retention.
- Figure 5 shows an intermediate engagement element 30 to be placed on the rafter 12 and to be received together with the rafter 12 in the longitudinal channel defined by the first longitudinal curved edge portion 21 of the top roofing element 20a.
- the intermediate engagement element 30 has an inverted U-shape making it suitable for being placed on top of a rafter 12 as best shown in figure 7 .
- the intermediate engagement element 30 is preferably made of stainless spring steel or the like, and it has inwardly pointing tips 31 which will engage with the opposed side surfaces of the rafter 12 and retain the intermediate engagement element 30. On both of its sides the intermediate engagement element 30 has outwardly pointing tips 32 which will engage with the ridges 22 on the sides of the longitudinal channel defined by the first curved edge portion 21, which is thereby in indirect engagement with the rafter 12.
- the second roofing element 20b is mounted and retained as explained above in connection with figures 1-3 . Depending on the retention strength required the number of intermediate engagement elements 30 per unit length can be varied accordingly.
- first and second longitudinal curved edge portions 21 and 23 of two elongate top roofing elements 20a and 20b is done manually whereby the second curved edge portion 23 is pressed by hand or using a suitable impact tool such as a rubber hammer. This has to be done along the full length of the top roofing elements.
- FIGS 8 and 9 is shown a tool 40 for use in this task.
- the tool 40 has a substantially C-shaped cross section and a longitudinal channel 41 dimensioned to accommodate the second longitudinal bead 23, and a longitudinal extending lateral opening 42 dimensioned to accommodate the longitudinal neck and with a width narrower than the second longitudinal bead 23.
- the operation can be as follows. First, an end portion of the second curved edge portion 23 is pressed e.g. by hand to snap over an end portion of the first curved edge portion 21. Next, the tool 40 is brought in a position where the thus assembled end portions 21 and 23 are received in the longitudinal channel 41 as shown in figures 10 and 11 , and the tool 40 is pushed e.g. by hand in a sliding movement in the direction of the arrow along the length of the top roofing elements 20a and 20b whereby the top roofing elements are assembled.
