Definitions

  • the invention relates to roof edges.
  • Roof edges are a very common construction element. They are used, inter alia, to protect walls from rainwater. Some existing roof edges comprise a bottom profiled section and a decorative panel which can be fastened to each other. The bottom profiled section ensures that the decorative panel is attached to the roof and the decorative panel determines the appearance of the roof edge. Such roof edges can be produced in a simple manner. An example of such roof edge is shown in EP 3 467 229 .
  • the bottom profiled section and the decorative panel are not always easily connectable to each other. Also, corners are often difficult to install. There is also a trade-off between the simplicity with which the bottom profiled section and decorative panel can be connected to each other and the strength of the connection between the bottom profiled section and the decorative panel.
  • roof edges in which the bottom profiled section and the decorative panel are easily connectable to each other There is also a need for roof edges whose corners are easily installable. There is also a need for roof edges in which the connection between the bottom profiled section and the decorative panel is very strong. Furthermore, there is a need for roof edges with a pleasing appearance from any angle. There is also a need for a roof edge in which the bottom profiled section and the decorative panel can easily be made in a different colour. There is also a need for roof edges which protect walls efficiently against precipitation. Furthermore, there is a need for roof edges which can be fitted easily, quickly and efficiently. Furthermore, there is a need for roof edges with excellent rectilinearity. Furthermore, there is a need for roof edges with excellent resistance to deformation.

During normal use, the façade lip (116) is situated very close to the wall on which the roof edge (100) rests, so that people are prevented from seeing the inside of the roof edge (100). If there were no protuberance (115), water would thus drip down via the façade lip (116) very close to the wall. As a result thereof, the wall would easily get wet, for example when it is windy. The protuberance (115) is provided in order to prevent this, since it ensures that rainwater trickles down at a suitable distance from the wall. Thus, the façade lip (116) and the protuberance (115) cooperate in order to provide an aesthetically pleasing roof edge (100) which keeps walls dry.
  • the length of the façade lip (116) can be chosen in accordance with the desired aesthetic appearance. In normal use, a relatively long façade lip (116) will cover a larger part of the wall on which the roof edge (100) rests, thus resulting in the roof edge being more prominent. On the other hand, a relatively short façade lip (116) will cover a smaller part of the wall on which the roof edge (100) rests, thus resulting in a less prominent roof edge (100).
  • the distance between the supporting plate (151) and the façade lip (116) is 4.0 cm smaller than the distance between the vertical support surface (125) and the supporting plate (151). By the same token, the distance between the vertical support surface (125) and the façade lip (116) is equally 4.0 cm. In this way, the façade lip (116) can be fitted close to the wall.
  • roof edges may be installed as follows:
  • one or more joint clips are furthermore also fitted in order to seal the cavity between two adjacent decorative panels.
  • the bottom profiled section is pre-punched. This makes fitting easier. In fact, if pre-punched bottom profiled sections are used, a roofer does not have to drill through the bottom profiled section during installation.
  • bottom profiled sections are fitted next to each other on the base surface.
  • a clearance is left between two bottom profiled sections which have been fitted next to each other in order to allow for thermal expansion of the profiled sections.
  • the bottom profiled sections in the present example are 3.0 m long, and a clearance of 5.0 mm is left between adjacent bottom profiled sections.
  • the roof covering is glued onto the bottom profiled section (120) in step d).
  • This has the advantage that a roofer can seal a roof using only a single layer of roof covering.
  • a flashing or an additional sealing strip of bitumen refers to a thin piece of material which is not permeable to water.
  • An example of a suitable flashing is a vulcanised EPDM strip with a width of approximately 0.5 m.
  • Both the bottom profiled section and the decorative panel are painted. These may be painted the same colour or different colours. In this way, it is possible to achieve a desired appearance, for example a colour accent or a uniform appearance.
  • One possibility is for the bottom profiled section and/or the decorative panel to be painted in the colour of the façade to which the roof edge is fitted.
  • Connecting rods (250,350) are used to attach bottom profiled sections (120) of straight parts (101) of the roof edge, on the one hand, to bottom profiled sections (220,320) of external corners (200) and internal corners (300), on the other hand.
  • the connecting rods are attached to the bottom profiled sections of internal corners (300) and external corners (200), and are inserted into openings (123) of the straight parts (101).
  • a reverse configuration is also possible.
