Description

A roof mounting device
The present invention relates, according to a first aspect, to a roof mounting device including a base configured to be rigidly fastened onto a roofing struc- ture,
The roof mounting device may, according to preferred embodiments, include an, integrated or not, roofing membrane such as a bituminous roofing membrane.
Background
The present invention generally relates to roof mounting devices of the type configured for retaining or supporting various structures on a building's roof.
Relatively light structures require, due to wind forces, a firm connection to the roof supporting the structure. The connections have to be able to withstand not only gravity-forces resulting from the weight of the structure, but also upwards and sideways forces induced on the structure, typically by the wind.
Today, such connections are obtained e.g. by securing a mounting device inter alia comprising a base plate, a sheet of a bituminous roof covering such as a bituminous roofing membrane, and means for receiving the object to be fastened, onto the roof. Typically, the means for receiving the object to be fastened onto the roof protrudes through the sheet of bituminous roof covering, such that, upon the base being secured to the roof and the sheet of bituminous roof covering being unified with the underlying roof membrane, the base is embedded in the roofs covering material.
In order to obtain roof mounting devices capable of resisting substantial upwards and sideways forces induced on the structure, today's practice is to design the mounting devices incl. base plate with material thicknesses allowing for sufficient strength such that the components of the device will not deform or fail under load. The result of increasing material thickness is increased weight as well as increased cost of manufacture and transport.
Brief description of the invention
The present invention seeks to significantly reduce material consumption as well as to reduce weight and cost of today's roof mounting devices. Further, the present invention seeks to set forth a roof mounting device having increased strength properties over today's roof mounting devices.
According to the invention, there is provided a roof mounting device as per the introductory part of this specification, and in particular, upon configuring the device such that the base includes two partially spaced apart and partially parallel sheets of structural material interconnected in selected portions or zones such that high stiffness and/or strength characteristics of the base are obtained, an improved roof mounting device resolving the abovementioned drawbacks are provided.
By spacing two relatively thin sheets of structural material apart, and interconnecting the sheets in selected portions or zones, a lightweight product having high strength or resistance characteristics is obtained. As an example, a compilation of two sheets of stainless steel each having a thickness of 0,5 mm, and spaced apart under partial interconnection such that the overall thickness of the compilation is about 5 mm, will have strength characteristics equivalent to that of an about 4 mm thick solid plate made from identical material. Such strength is obtainable by interconnecting the thin sheets of material in relatively few, preferably coherent, zones. As an example, a 390 mm square base plate, or flange, made up from two 0,5 mm sheets of stainless steel which is spaced apart such that the overall thickness of the compilation is about 5 mm, need to be interconnected, possibly by welding, in three annular and coherent zones only in order to reach a strength equivalent to that of a 4 mm solid stainless steel plate. According to one embodiment, the base may constitute two or more interconnected and spaced apart parallel sheets of structural material. The structural material may constitute stainless steel or steel, and the sheets may be coated by PVC or equivalent. Further, it will be possible to provide a base made from relatively high strength non-steel products such as glass fibre or equivalent. Such non-weld able materials may be interconnected by means of glue, screws or rivets etc. Alternatively, the base may be made as an integral part or unit by a process suitable for providing holtow-bodied items. Such process could constitute blow moulding or equivalent. According to one embodiment, the structural material may be stainless steel or equivalent.
According to one embodiment, the spaced apart sheets of structural material each may have a thickness of in-between 0,1 mm and 2 mm, alternatively 0,25 mm and 1 , or possibly at thickness of 0,5 mm.
According to one embodiment, the spaced apart sheets of structural material may be spaced apart such that the base has a thickness of in-between 2,5 mm and 10 mm, alternatively 4 mm and 6 mm.
According to one embodiment, the spaced apart sheets of structural material may be interconnected by at least one welding.
According to one embodiment, the welding may constitute at least one co- herent welding applied along a periphery of the base. According to one embodiment, the sheets of structural material may be interconnected by means of welding in at least two welding zones, where each welding zone is provided with a coherent welding obtained by friction welding. Alternatively, the welding may be obtained by means of spot welding, soldering, clinching or equivalent.
According to one embodiment, the sheets of structural material of the device may be interconnected by means of welding in at least three encircling welding zones, where each welding zone is provided with a coherent welding.
According to one embodiment, the base may be chamfered along its periphery such that the spaced apart parallel sheets are not spaced apart along the periphery of the base. Such chamfering may result in a smooth transition between the roof covering of the device and the roof whereon the device is in- stalled.
According to one embodiment, the device may further comprise an operative part configured to protrude through a roof covering material. According to one embodiment, the operative part configured to protrude through a roof covering material may constitute a roof anchor or bracket for receiving a structure to be mounted on or above a roof covering.
According to one embodiment, the device may further comprise a sheet of bituminous roof covering connected, by means of a sealed connection, to the operative part and/or the base. The roof covering may extend beyond the base such that the sheet of bituminous roof covering may be welded onto an underlying roof covering when the device is mounted on a roof.
According to one embodiment, the device comprising a sheet of bituminous roof covering may be configured to be mounted on a roof covered with a bi- tuminous roofing membrane whereby the device will, upon installation, form an integrated part with the roof.
According to one embodiment, the device may further comprise a sheet of foil or film connected, by means of a sealed connection, to the operative part and/or the base. The foil or film may extend beyond the base such that the sheet of foil or film may connect onto an underlying roof covering.
According to one embodiment, the base may be provided with holes or aper- tures configured for receiving fastening means such as screws or bolts.
According to one embodiment, the holes or apertures may be configured such that an access hole or aperture may be provided in an upper sheet of the structural material, and a fixing or retaining hole or aperture may be pro- vided in the lower sheet of structural material such that fastening or connecting means may, after installation, be embedded in the base, whereby a smooth installation may be obtained.
According to one embodiment, the portion of one or both of the spaced apart sheets of structural material may provided with raised zones inter alia defining welding zones and a thickness of the base.
According to one embodiment, the raised zones may be provided by means of deep drawing.
According to one embodiment, the device may constitute a solar panel roof mounting device.
According to one embodiment, the device may constitute a solar panel roof mounting device. Brief description of the drawings

Detailed description of the invention with reference to the figures
As can be seen in figure 1 , the device according to the present invention may take the form of a substantially square flange with round off corners. The present invention is not in any way limited to this particular shape, and it is alleged that the present invention will be equally beneficial under embodi- ments wherein the base or flange 10, 20 is provided e.g. as a not shown circular or rectangular flange.
Referring to the cross-sectional views according to figures 2 and 3, where figure 3 is an enlarged view of the encircled portion 50 of figure 2, it is clear that the base according to the illustrated embodiment constitute a base made up from an upper sheet of structural material 10 and a lower sheet of struc- tural material 20, The upper and lower sheets of structural material, or plates, are interconnected by welding 5 in the areas 6. Although not shown in the figures, the base may be manufactured by interconnecting a plurality of parallel sheets of structural material or plates, and also, depending of the overall dimensions of the base incl. the forces intended to be obtained by the base, the sheets of structural material, or plates, may be interconnected in more than the shown three welding zones.
The lower sheet of structural material or plate 20 is in the shown embodiment deep drawn in two coherent encirclements closest to the centre of the base to form welding zones 6 as well as define the thickness t2 of the base.
The upper sheet of structural material or plate 10 is in the shown embodiment also deep drawn, however here to define a peripheral welding zone 6 and also to define the thickness t2 of the base.
Although not shown in the figures, the present invention may also be embodied with one of the upper or lower sheets of structural material or plate 10, 20 provided as a flat member, where the other may be provided with bucklings or swells in order to set the sheets of structural material or plates apart and define the interconnecting and reinforcing welding zones.
The significant strength of the compilation of the sheets of structural members, or plates, is obtained partially by the bucklings or swells applied to the structural members and partially by the interconnection of the upper and lower structural members. Consequently, one or both of the upper or lower structural members may be provided with additional bucklings or swells, interconnecting the other structural member or not, and thereby increase the strength of the device. Figure 4 is a perspective view of a device according to the present invention incl. a bracket and a sheet of bituminous roof covering. The cut-out in the illustration clearly show the chamfered periphery of the base. Further, it is clear from figure 4 that the bituminous membrane 30 extends beyond the footprint of the base.
Figure 5 is a sectional view through the device according to figure 4,
The invention is not intended to be limited to the embodiments presented as examples above. The invention is however intended to be applied widely and inter alia within the scope of the inventive idea as defined in the appended claims.
The term "comprises/comprising/comprised of when used in this specifica- tion incl. appended claims is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
