Abstract

A roof structure for a greenhouse or warehouse comprising mutually parallel gutters (1) extending in a longitudinal direction and a raised cover (2) extending between the gutters. The cover comprises a support structure (3, 5) supported on the gutters, an outermost translucent cover layer (15) as well as an innermost translucent cover layer (7) which together delimit a cavity (8) and which are supported by the load-bearing structure (3, 5). The roof structure is provided with a ventilation duct (12) that extends along the cavity (8) and that is connected by at least one opening (11) to the interior of the cavity, wherein the ventilation duct is adapted for exchanging a gas as ventilation medium between the ventilation duct and the cavity through at least one opening, for ventilating the internal space of the cavity. At least one of the gutters (1) comprises a tubular shape which defines the ventilation duct (12).

2. The roof structure according to claim 1, wherein at least one of the cover layers comprises a film (7).
3. The roof structure according to claim 2, wherein a fastening section (6) with undercut chamber is located on opposite sides of the cavity (8), wherein the film (7) has a respective longitudinal member (9) on opposite edges, and wherein each longitudinal member extends into the undercut chamber of the respective fastening section.
4. The roof structure according to any one of claims 1-3, wherein the ventilation duct (12) is connected to the interior of the cavity (8) by a series of openings extending in the longitudinal direction or a groove, and wherein the ventilation duct is adapted to supply or discharge the ventilation medium via that ventilation duct and the opening(s) or the groove to or from the cavity.
5. The roof structure according to any one of claims 1-4, wherein the tubular shape that defines the ventilation duct (12) is also adapted for discharging condensation water from the inside of at least one of the cover layers (7, 15). 16
6. The roof structure according to claim 5, wherein the gutter (1) is provided with a condensate receiving ledge (10) beneath at least one of the cover layers (7, 15), wherein the openings (11) or groove is/are located at the level of the condensate receiving ledge.
7. The roof structure according to any one of claims 1-6, wherein the cavity (8) is compartmentalised in the transverse direction.
8. The roof structure according to claim 7, wherein a compartmentalisation wall extends inside the cavity in the transverse direction thereof, which is connected to the outermost and innermost translucent cover layers (15, 7).
9. The roof structure according to claim 7, as far as dependent from claim 2, wherein the film (7) between both longitudinal edges thereof is fastened to the other cover layer via a fastening structure which extends in the transverse direction.
10. The roof structure according to any one of claims 1-9, wherein the cavity (8) is delimited by a seal (4) with at least one closable opening (14), preferably a series of closable openings extending in the longitudinal direction of the seal or a closable groove, which opens into the internal space of the cavity.
11. The roof structure according to any one of claims 1-10, comprising an active fan (13) for exchanging ventilation medium with the internal space of the cavity (8).
12. The roof structure according to claim 11, as far as dependent from claim 4 or 6, wherein the active fan (13) is connected to the ventilation duct (12) inside the tubular gutter (1).
13. The roof structure according to any one of claims 1-12, comprising at least one further opening (14) for supplying and/or discharging the ventilation medium to/from the interior of the cavity (8), wherein the at least one opening (1 1) and the at least one further opening (14) are located at different heights. 17
14. The roof structure according to claim 10 or 13, comprising at least one valve (17) for opening or closing the at least one opening (11) and/or the at least one closable opening (14).
15. The roof structure according to any one of claims 1-14, comprising a ridge located between the gutters but at a higher level, rods running on opposite sides of the ridge and inclined downwards towards an associated gutter, an outermost cover layer made of translucent panels between mutually parallel rods and a gutter, wherein the innermost translucent cover layer extends under a series of rods and panels on one side of the ridge.
16. The roof structure according to claim 15, wherein the cavity (8) is delimited by the ridge (5).
17. The roof structure according to claim 15, wherein the cavity (8) is delimited by a longitudinal beam (4) lying between the gutter and the ridge.
18. The roof structure according to claim 17, wherein a ventilation window is provided, which is hingedly connected on one edge to the ridge or the longitudinal beam, and which on the opposite edge cooperates with the longitudinal beam or the ridge.
19. The roof structure according to any one of claims 1-18, wherein the cavity (8) has a uniform thickness.
20. A method for operating a roof structure for a greenhouse or warehouse, which roof structure comprises mutually parallel gutters (1) and a raised cover (2) extending between the gutters, wherein the cover is provided with a support structure (3, 5) supported on the gutters, an outermost translucent cover layer (15) as well as an innermost translucent cover layer (7), which jointly delimit a cavity (8) and which are supported by the support structure (3, 5), wherein the roof structure is provided with a ventilation duct (12) that extends along the cavity (8) and that is connected via at least one opening (1 1) to the interior of the cavity, wherein at least one of the gutters (1) 18 comprises a tubular shape which defines the ventilation duct (12), wherein the method comprises:
keeping the air in the cavity (8) stationary during a first time period to provide an insulating effect of the cover, and
- during a second time period outside the first time period, supplying air in a first region of the cavity and discharging air from another region of the cavity at a distance from the first region to create a heating effect, a cooling effect and/or a drying effect in the cavity.
21. The method according to claim 20, for operating a roof structure provided with an active fan (13) for supplying or discharging a ventilation medium to or from the internal space of the cavity (8), wherein the method comprises:
keeping the active fan inoperative during the first time period,
activating the fan during the second time period.
22. The method according to claim 20 or 21, for operating a roof structure provided with a closable opening (14) for supplying and/or discharging a ventilation medium to/from the interior of the cavity (8) and providing at least one valve (17) for opening or closing the at least one closable opening (14), wherein the method comprises:
- keeping the at least one valve closed during the first time period,
- keeping the at least one valve open during the second time period.
23. The method according to any one of claims 20-22, wherein the supply and discharge of air during the second time period comprises:
- discharging air from the cavity (8) via the at least one opening (11) through the ventilation duct (12) and supplying air from an inner part of the greenhouse or the warehouse into the cavity (8) to create the heating effect, the cooling effect and/or the drying effect inside the cavity.
