Description

Elongated member for roofing panel mounting, roofing panel system and comprising the same
Field of the invention
The invention relates generally to roofing panel mounting systems, in particular for seam metal roofs. This invention relates also to an elongated member for roofing panel mounting, and to a roof comprising the elongated member according to the invention.
Background
Sheet metal roofing systems are generally formed of a series of elongated sheet metal roofing panels mounted on a roof substrate in side-by-side relation, and joined together at their adjacent longitudinal side edges by a so called standing seam type water-tight joint. The roofing panels are typically made of either low carbon steel or stainless steel sheet metal, and are generally channel-shaped form, each comprising a flat base portion provided along its opposite longitudinal side edges with upstanding wall portions, one of which is formed at its top with an inturned horizontal top flange portion, and the other one of which is formed at its top with an outturned horizontal top flange portion terminating in a downturned edge flange.
A typical roofing panel 100 is shown in figure 1 . It is in the form of an elongated, channel- shaped sheet metal pan, and comprises of a base portion 101 , side wall portions 102 and 103 of approximately equal height. The side wall portions 102, 103 are provided along their top edges with respective horizontally extending lateral flanges 104 and 105 of approximately equal width. Horizontal is the z-direction of the coordinate system 199. The flange 105 is inturned while flange 104 is outturned in respect to the base portion 101 . The flange 104 is provided along its outer edge with a seam flange 106 extending downwardly alongside the outer edge of the inturned side edge lateral flange, and spaced from the wall portion 102 a distance slightly greater than the width of the inturned flange 105 so as to receive therebetween the inturned flange 105 of an adjacent panel during the fabrication of the roof assembly.
The roofing panels are typically installed down in place onto a roof substrate by using plurality of roofing panel mounting clips. An exemplary roofing panel mounting clip 210 is shown in figure 2. The clip comprises a tab 21 1 and a base flange 212. The tab 21 1 comprises a web 213 substantially perpendicular to the base flange, a lateral flange 214 extending substantially in x-direction of the coordinate system 299, and a substantially downwardly extending seam flange 215. Downward direction is the - y-direction of the coordinate system 299. The base flange is adapted to be secured to a roof substrate by nails or other suitable fasteners, whereas the tab is adapted to be engaged with a longitudinal flange of one of two contiguous roofing panels, which are subsequently joined by seaming inter engaged longitudinal flanges together to form a so-called standing seam in which the tab member is interleaved. The horizontal base flange has preferably a hole 216 for fastening means. The size and shape of the clip can be chosen based on the roofing panels used in the installation.
The use of roof panel mounting clip of figure 2 has few disadvantages. Typically, up to 10 clips are needed for m2 of roofing. Thus the assembler has to carry numerous clips in his/her pockets. Handing of the clips especially when using installation cloves is cumbersome and thus the clips are often dropped. Falling clips may be a serious problem especially when installing steep roofs for high apartment houses and the like.
The clips have to be installed one by one, since they are prone to slide on the roofing panels. Thus the assembler has to hold the clip on place when using an installation instrument such as a nail gun. This in turn is time consuming, and may also be dangerous especially when working close to the roof edges. The above mentioned problems have been solved in EP 2772595 and US 2003145548 by using elongated members for roofing panel mounting. An exemplary state of art elongated member 310 is shown in figure 3. It comprises tabs 31 1 a,b adapted to be engaged with a roofing panel, and a base flange 312 adapted to be anchored to a roof substrate via fastening means. A further problem related to roofing panel installation is that the roofing panels and the elongated members are prone to slide on the roof substrate. The steeper is the roof substrate, the more serious is the problem. Accordingly, very often one assembler has to keep the roofing panel and the elongated member in place and another assembler fastens the panel and the elongated member to the roof substrate. Alternatively, the panel has to be kept in place by using tools such as clamps. Accordingly, there is need for an improved roof panel mounting system. Summary

The holding means is preferably an additional flange in the first end of the base flange. The holding means is out turned in respect with the base flange and extends substantially sideward, i.e. towards x-direction in respect of the coordination system, 499. The shape, size, and the bending angle γ can be varied as needed . An exemplary holding means is a two-folded piece of material of the elongated member. If the thickness of the material of elongated member is 0.6 mm, then the thickness of the holding means according to this exemplary embodiment is 1 .2 mm. According to a particular embodiment, the holding means is an extension of the flange 417a. An exemplary length of extension is 10 mm.
According to a preferable embodiment, the base flange includes plurality of holes 416 for the fastening means, such as nails, bolts or screws. The holes are for assisting the assembly. According to a particular embodiment, there are as many holes in the base flange as there are tabs, and each hole is in proximity of each tab.
The elongated member can be manufactured on any suitable material used for roofing. Exemplary materials are Zn-tin, low carbon steel or stainless steel . An exemplary thickness of the material is 0.6 mm. Figure 5 shows a front view of an exemplary roofing panel system 520. It comprises a roofing panel 500 and an elongated member 510 engaged to the roofing panel. The elongated member comprises a base flange 512, and a tab 51 1 comprising a web 513 extending from a first side 512a of the base flange. The web is preferably substantially perpendicular to the base flange. The tab comprises also a lateral flange 514 extending from the web. The lateral flange is preferably substantially parallel to the base flange, and is out turned in respect with the base flange. In addition, the tab comprises a seam flange 515, extending from the lateral flange. The holding means 518, positioned in the first end 512A of the base flange, is omitted from figure 5 for clarity. Profile of the roofing panel and the elongated member is such that they can me joined together tight enough so that the junction between the elongated member and the roofing panel parts allows transportation and/or installation of the roofing panel system to a roof substrate. According to a particular embodiment shown in the figure, the junction is tightened by bending the seam flange 515 so that the tab 51 1 encloses a lateral flange 504 of the roofing panel.
Another exemplary roofing panel system is shown in figure 6. The figure shows a top view of a roofing panel system 620. The system is as that shown in figure 5, but it further shows the holding means 618 bent around a side wall 602 of the roofing panel and plurality of holes 616 for the fastening means.

According to one embodiment, the method includes mounting of roofing panels to a roof substrate with an elongated member according to any of claims 1 -6. According to another embodiment the method includes providing roofing panel systems according to any of claims 7-9, and mounting the roofing panels to a roof substrate.
When assembling roofing panels, the elongated member comprising a holding means is assembled so that the holding means is preferably towards the roof eaves. During assembly, the holding means is bent around the seam of the accompanied roofing panel so that the elongated member is locked in its position. When locked, the angle γ is close to 0°.
Roof installation includes typically fastening of roofing panels and elongated members to the roof substrate by using fastening means such as nails. Accordingly, if the fastening means puncture holes e.g. in the under-cladding, and potential leaking sites are formed. Formation of the holes can be avoided by using an elongated member comprising isolating means 419, 519 adapted to be positioned between the base flange and the roof substrate. A particular isolating means comprises bitumen. Exemplary isolating materials are preferably bitumen felt and bitumen gum.
The holding means gains advantages. It allows installation of a row of roofing panels prior to seaming, which makes the assembly faster and safer. In addition, the use of clamps or other tools to hold the roofing panels in place during assembly can be avoided.
According to another embodiment the present invention concern a roofing panel system comprising a roofing panel and an elongated member according to the present invention. An exemplary roofing panel 100 that can be engaged with an elongated member of the present invention is shown in figure 1 . Roofing panel systems 520, 620 according to an exemplary non-limiting embodiment of the present inventions are shown in figures 5 and 6.
According to still another embodiment the present invention concerns a roof comprising an elongated member according to the present invention. Exemplary elongated member 410 is shown in figure 4. According to still another embodiment the present invention concerns use of an elongated member such as 410 shown in figure 4 for roof installation.
According to still another embodiment the present invention concerns use of the roofing panel system such as 520, 620 shown in figures 4 and 5, respectively, for roof installation.
The specific examples provided in the description given above should not be construed as limiting the scope and/or the applicability of the appended claims.
