Definitions
- the invention relates to a greenhouse with a hanging foil roof according to the preamble of claim 1, as is known, for example, from EP 1 250 835 B1 or DE 202018 102937.
- a greenhouse is usually an artificially heated glass house to attract and raise plants such as flowers, ornamental plants, tomatoes or other vegetables regardless of the climatic conditions. Greenhouses are usually equipped with ventilation and occasionally with additional lighting and irrigation systems.
- the film greenhouse known from EP 1 250 835 B1 has a roof that can be easily opened and closed and, if necessary, brought into various intermediate positions. This is done first by the fact that the foil forming the roof remains in every position below a light but stable structure on which it is suspended. When several greenhouses are arranged next to one another in blocks, good ventilation via the side walls, as the prior art in FIG. 1 shows, is not guaranteed, since sufficient draft cannot be produced over the entire width of all greenhouses. In summer, when the outside temperature is high, this leads to major problems for plant growth, which is inhibited or even harmful, especially with tomatoes above around 24 ° C.
- the invention is therefore based on the object of designing a greenhouse suitable for a row arrangement in such a way that it ensures, on the one hand, a good air flow for ventilation and, on the other hand, for the ventilation even under extreme weather conditions such as high outside temperatures due to strong sunlight, storms, heavy rain or snow Provides plants with the necessary protection.
- claim 1 with alternating upward and downward gables results in the possibility specified in claim 4 of forming an air passage opening in each case between the horizontal longitudinal edges of successive roof gables. This significantly improves the air circulation, especially in the area under the foil roof, so that the air flow is increased.
- the air passage opening created with this measure can be closed by a shutter-like barrier film in order to thereby adapt the temperature conditions to the respective requirements.
- the gable roof consists of tubular, double-layer fields with an upper side reflecting IR rays and a lower side with diffuse radiation.
- this becomes too strong thanks to the IR Ab radiation Solar radiation reflects, while the diffuse film on the underside of the film field retains the heat inside the greenhouse.
- the tubular fields of the foil roof can be clamped in holders with a C-shaped cross-section by means of clamping elements.
- heating lines are integrated into the tubular, double-layered fields, so that the tubular fields can be heated even at low outside temperatures.
- Figure 1 is a schematic view of a known line-up of three greenhouses here in stand construction according to the prior art
- FIG. 2 is a view of two interconnected greenhouses according to the invention
- Figure 3 is a longitudinal section of the greenhouse of Figure 2
- FIG. 4 shows an enlarged side view of one of the two greenhouses of FIG. 3
- FIG. 5 shows a schematic sectional illustration of a gable field of FIG. 4
- FIG. 6 a variant of FIG. 5
- FIG. 7 shows a tandem arrangement of two tubular gable panels with their clamping elements
- FIG. 8 a variant of FIG. 7.
- the row greenhouse 10 ‘according to the prior art shown in FIG. 1 consists of a series of three greenhouses 10 in post construction with frame-shaped supports 12 of a supporting structure 14 on which horizontal lattice girders 16, not shown in FIGS. 3 and 4, are attached.
- FIG. 3 shows a tandem arrangement of two greenhouses 10 according to the invention, the foil roof 20 hanging on the lattice girder 16 in each greenhouse 10 consisting of two triangular gables 28, the ridge lines 22 of which are directed alternately upwards and downwards.
- a roof structure is created in which in each greenhouse 10 a conventional roof with a triangular gable 28 with a ridge line 22 (A-shape) at the top with a V-shaped gable 28 'with a downwardly hanging "Firsf" (center line 22 ') alternates.
- an air passage opening 32 is formed between the horizontal longitudinal edges 30 of successive roof fields 28, which also enables an air exchange indicated by arrows directly below the lattice girder 16 located above.
- each air passage opening 32 can be opened and closed by a shutter-like closure film 34.
- FIGS. 3 and 4 it is indicated that due to the tandem arrangement of two greenhouses 10 between each one in the lower one Area closed support 12 is formed, above which a closable air passage opening 32 is located.
- the two outer supports 12 can, as indicated in FIGS. 3 and 4, be designed as closed walls 54 which have air inflow openings 32 in the lower and / or upper area.
- tensioning elements 36 are attached in the area of the ridge lines 22 and center lines 22, which can be designed as springs or hydraulic cylinders (not shown) that are controlled by the temperatures involved.
- the foil roofs 20 in the A-arrangement and in the V-arrangement consist of tubular fields 24, for which the FIGS. 5 to 8 show exemplary embodiments.
- a field 24 which consists of a double-layer tubular film 48, the longitudinal edges of which are welded to one another.
- the upper side 40 and the lower side 42 are formed from strips of different foils, the upper side 40 being made of a material that reflects IR rays, while the lower side 42 causes diffuse radiation so that the heat is retained within the greenhouse 10 .
- the double-layer tubular shape of the field 24 is clamped between two opposing holders 44 with a C-shaped cross section, for which purpose cylindrical (FIG. 5) or approximately semicircular cross-section clamping elements 46 (FIGS. 6 to 8) are used.
- FIGS. 7 and 8 show the cross section through a field 24 with two tubular double foils 48, which each enclose an air cushion 50 and form a further air cushion 50 ‘between them.
- heating lines 52 which consist of a ribbed hose, can be integrated in the tubular, double-layered fields 24 through which hot water flows.
- a shading cover is arranged over the foldable foil roof 20, which consists of a light-absorbing foil or such a fabric and advantageously consists of a hail-proof material that rests on the lattice girders 16 of the supporting structure 14.
