Assembled roof element particularly intended for a skylight barrel vault

Description

[0001] The present invention relates to a roof comprising an assembled roof element comprising at least one first profiled plate which is manufactured from a composite material and which serves as element supporting the assembled roof element.

[0002] In this paragraph a number of examples of known roof elements for skylight barrel vaults are described. A roof element which is common in Belgium is constructed from one or more profiled plates which are manufactured from a polyester resin reinforced with glass fibres. These are referred to as PRV (polyester renforcé de fibres de verre) skylight barrel vaults. In such skylight barrel vaults the U-value is relatively high. The U-value, or coefficient of heat transmission (W/m²K), indicates how much heat is lost per second through 1 m². Therefore, the lower the U-value, the better the roof element insulates.

[0003] BE 883519 discloses a roof according to the preamble of claim 1.

[0004] Another known skylight barrel vault is constructed from a combination of aluminium curved profiles for supporting multi-walled polycarbonate plates. Such a construction has the drawback that expensive aluminium profiles are necessary.

[0005] The present invention has for its object to propose a roof comprising an assembled roof element for which the desired U-value and rigidity can be obtained in simple manner with an inexpensive construction in which expensive aluminium supporting profiles are not necessary.

[0006] The invention is distinguished for this purpose in that the roof element comprises the features of the characterising part of claim 1.

[0007] The first plate of a composite material functions here as the supporting element, while the U-value can be brought to the desired value by a suitable choice of a multi-walled plate. The second plate is a flexible multi-walled plate.

[0008] The composite material is a resin from the group of: polyester resin or other thermoset resins. Glass fibres can optionally be added to further strengthen the material.

[0009] The plastic material of the second plate is a material from the group of: polycarbonate, acrylate, PET or other thermoplasts. These materials have the advantage that light-transmitting, flexible and light multi-walled plates can be manufactured, for instance by extrusion. The top side of the second plate must here preferably be given a UV-resistant form.

[0010] For an improved strength of the first profiled plate of composite resin, this plate can have a ribbed profile in longitudinal section. The profiled supporting plate preferably describes an arcuate form in transverse direction.

[0011] The multi-walled plates are preferably provided on two transverse sides with a connecting profile, whereby the transverse sides of two adjacent second plates can be connected to each other. This can for instance be a protruding transverse part on a first transverse side and a transverse recess on the other transverse side, which can be mutually engaging.

[0012] According to a possible embodiment the multi-walled plate is bent close to the longitudinal side for mounting these longitudinal sides on an upstand. This can typically take place by means of a simple bending process.

[0013] According to another possible embodiment the first and second plate can be mounted on an upstand by means of a mounting profile, optionally with additional clamping profile.

[0014] The invention will be further elucidated on the basis of a number of non-limitative exemplary embodiments of the assembled roof element according to the invention, with reference to the accompanying figures, wherein:

figure 1 is a schematic cross-section of a roof according to the invention comprising an assembled roof element arranged on upstands;

figures 2 (A), (B), (C), (D) show four possible variants for mounting of the roof element on the upstand;

figures 3 (A), (B), (C) show three possible longitudinal sections of the ends of a multi-walled plate of an assembled roof element ;

figures 4 (A), (B) show two possible longitudinal sections of the first plate of composite resin of an assembled roof element.

[0015] The same components are designated in the figures with the same reference numerals.

[0016] The assembled roof element shown in cross-section in figure 1 comprises one first curved plate 1 manufactured from a composite resin and one second multi-walled plate 2 of a plastic material. The second multi-walled flexible plate is supported by the first rigid plate 1. This embodiment is typically used in so-called skylight barrel vaults, wherein a number of such assembled roof elements can be arranged adjacently of each other in longitudinal direction on upstands 3.

[0017] Figure 2(A) shows a first method of mounting the roof element on upstand 3. The supporting first plate 1 is pushed into a profile 4. Second plate 2 is fixed by means of a clamping profile 5. In the shown embodiment this clamping profile 5 engages behind a protruding rib 17 of profile 4 and in a recess 18 which is provided on the top side of plate 2, close to the longitudinal side thereof.

[0018] Figure 2(B) illustrates a second method of connecting the roof element to the upstand. First and second plates 1, 2 are herein mounted on upstand 3 by means of a mounting profile 4 fixed to the upstand and having two longitudinal channels for the respective longitudinal sides of plates 1, 2.

[0019] Figure 2(C) shows a third variant in which the second plate is bent along a longitudinal seam 5 and connected to the upstand by means of a screw 6.

[0020] Figure 2(D) shows a fourth variant in which plate 1 is connected by means of a screw 8 to an upstand with an oblique top side and plate 2 is connected by means of a screw 7 to the first plate.

[0021] Note that these are only a number of examples and that any method known in the art suitable for the roof element can be employed.

[0022] Figures 3(A)-(C) show three examples of a second plate in longitudinal section.

[0023] According to a first variant, which is shown in figure 3(A), two adjacent second plates are mutually connected in longitudinal direction by an overlapping and snapping connection. In the shown embodiment a first transverse side of a second plate is provided for this purpose with a substantially gutter-like part 20 with a downward directed opening, and the other transverse side is provided with two flexible, upward directed ribs 21, 22. This gutter-like part 20 and ribs 21, 22 co-acting therewith are formed such that the ribs can be snapped into the gutter-like part. This gutter-like part 20 and ribs 21, 22 can be manufactured integrally with second plate 2.

[0024] A second variant, shown in figure 3(B), has a protruding transverse part 10 on a first transverse side thereof, and a transverse recess 9 on a second transverse side. In this manner adjacent second plates can be mutually connected in simple manner. According to a second variant, shown in figure 3(C), a transverse side is provided with a vertical flange 12, which can be arranged in a transverse gutter 11 on the other transverse side of an adjacent plate 2. Once again it is possible to envisage many other variants which are known to the skilled person.

[0025] Finally, figure 4 shows two examples of a first plate 1 in longitudinal section. According to a possible embodiment, strengthening ribs 13 are provided in transverse direction, wherein one transverse rib 13 overlaps in each case with a transverse rib 13' of an adjacent plate. According to another possibility shown in figure 4(B), the first curved plate is plane and a gutter-flange 15, 14 connection is used to mutually connect adjacent plates.

[0026] The invention is not limited to the above illustrated examples, and the scope of protection is defined solely by the appended claims.
