A glass supporting system for a greenhouse comprises a horizontally oriented beam (2) and an insulated glass panel (6) which has an outer side (7), an opposite inner side (8) and a circumferential rim (9) extending between the outer side (7) and the inner side (8). An edge portion of the insulated glass panel (6) is supported by a first support (10) of the beam (2) which contacts the rim (9) and a second support (11) of the beam (2) which contacts the inner side (8). The second support (11) is located at a base (12) of the beam (2) that extends below the first support (10). The insulated glass panel (6) is inclined upwardly in a direction away from the beam (2). The glass supporting system comprises an opening between a lower side of the first support (10) and the base (12) for allowing water to flow in a direction away from the second support (12) and pass the lower side of the first support (10).
A method of applying a foil on an inclined roof structure having a ridge beam, a gutter, a plurality of parallel roof bars interconnecting the beam and the gutter and a ventilation opening frame which surrounds an opening that is located between the beam, the gutter and two neighboring bars, comprises: supplying a window frame that fits inside the ventilation opening frame, introducing the window frame within and holding the window frame at a fixed position with respect to the ventilation opening frame, laying a foil onto the roof structure such that it extends at least from the beam to the gutter and covers at least the neighboring roof bars, fixing the foil to the window frame and the ventilation opening frame along respective circumferential edges thereof, cutting the foil between the window frame and the ventilation opening frame, hence forming the window frame including the foil.
A greenhouse (1) includes an inclined roof (2) which is provided with a closable window (6), which has a frame (7) including a transparent cover (13). The frame (7) comprises a lower profile (8), an upper profile (9), a first side profile (10) and a second side profile (11) which are fixed to each other such that the first and second side profiles (10, 11) extend between the upper and lower profiles (8, 9). In a closed condition of the window (6) the frame (7) rests on a circumferential edge of the roof (2) and the lower profile (8) is located at a lower height level than the upper profile (9). At least one of the lower profile (8) and the first side profile (10) has a gutter (18, 22, 25, 26, 28, 33, 35) extending in its longitudinal direction for transporting water such as condensate from the interior of the greenhouse (1). At least the lower profile (8) and the first side profile (9) are mounted to each other through a corner connector (14), which has a first portion (16) which is fixed to the lower profile (8) and a second portion (17a, 17b) which is fixed to the first side profile (10). The corner connector (14) has a core (15) which is located between the first and second portions (16, 17a, 17b) and between the lower profile (8) and the first side profile (10) and which is provided with a drain opening (29) that communicates with the gutter (18, 22, 25, 26, 28, 33, 35) and is located below the gutter (18, 21, 22, 25, 26, 28, 33, 35) in the closed condition of the window (6) so as to drain water from the gutter (18, 22, 25 25, 26, 28, 33, 35).
A method of applying a foil (10) on an inclined roof structure (1), wherein the inclined roof structure (1) comprises a ridge beam (2), a gutter (3) extending parallel to the ridge beam (2), a plurality of parallel roof bars (4) interconnecting the ridge beam (2) and the gutter (3) and a ventilation opening frame (7) which surrounds a ventilation opening (8) that is located between the ridge beam (2), the gutter (3) and two neighbouring roof bars (4), comprises the steps of: supplying a window frame (9) which is complementary to the ventilation opening frame (7) and fits inside the ventilation opening frame (7), introducing the window frame (9) within the ventilation opening frame (7) and holding the window frame (9) at a fixed position with respect to the ventilation opening frame (7), laying a foil (10) onto the inclined roof structure (1) such that it extends at least from the ridge beam (2) to the gutter (3) and covers at least the neighbouring roof bars (4), fixing the foil (10) to the window frame (9) and the ventilation opening frame (7) along respective circumferential edges thereof, cutting the foil (10) between the window frame (9) and the ventilation opening frame (7), hence forming the window frame (9) including the foil (10).
A greenhouse has a roof including a plurality of substantially parallel crossbeams, at least two longitudinal sections which are mounted to the crossbeams and extend at a distance from each other in transverse direction of the crossbeams, a transparent foil which is mounted to the longitudinal sections at respective foil attachment locations thereof so as to form a cover between the longitudinal sections. The roof also includes a displacement mechanism for displacing one of the longitudinal sections with respect to the other between a non-foil-stretching position and a foil-stretching position. The distance between the respective foil attachment locations is larger in the foil-stretching position than in the non-foil-stretching position. The displacement mechanism can be operated and is lockable at an upper side of the roof.
A greenhouse (1) has a roof (2) including a plurality of substantially parallel crossbeams (3, 3'), at least two longitudinal sections (4, 5, 24, 5') which are mounted to the crossbeams (3) and extend at a distance from each other in transverse direction of the crossbeams (3), a transparent foil (6) which is mounted to the longitudinal sections (4, 5, 24, 5') at respective foil attachment locations (7) thereof so as to form a cover between the longitudinal sections (4, 5, 24, 5'). The roof (2) also includes a displacement mechanism (8, 8') for displacing one of the longitudinal sections (5, 5') with respect to the other (4, 24) between a non-foil-stretching position and a foil-stretching position. The distance between the respective foil attachment locations (7) is larger in the foil-stretching position than in the non-foil-stretching position. The displacement mechanism (8, 8') can be operated and is lockable at an upper side of the roof (2).
