The invention relates to agriculture and can be used in greenhouses and other structures protected ground.

Known combined fence greenhouses made of glass and film in the form of a two-layer film of the fence with an air gap located above the glazed roof ("Greenhouses and greenhouses. The Handbook." Edited Him. Ed. "The harvest", Kiev, 1993, s).

A disadvantage of the known barriers is the high complexity of the installation, film fences, and that to ensure the melting of snow during snowfall on the outer surface of the double-layer fencing needs to maintain a higher temperature in the upper zone of the greenhouse or strengthen the building structure.

The aim of the invention is the provision of reducing the complexity of mounting a film coating on the roof of the greenhouse, as well as the possibility of regulating thermal performance of roof depending upon weather conditions by transforming an additional film of the fence.

This objective is achieved in that the fence greenhouses containing multilayer film guard is made of panels with an air gap placed above the glazed roof according to the invention, between the layers of film panels installed fenestration of polim the turning cylinders for air.

In a preferred embodiment, the fence edge film panels fixed in a removable semi-rigid composite cords and secured in the sockets on the roof of the greenhouses, and the fixing film panels in a semi-rigid composite cords carried out by pushing the elastic retaining cord together with the edge of the cloth in the side reversibly-deformable groove shaped main cord.

Preferably the Central groove of the main cord is pressed reversibly-deformable shell retainer cord, into which is inserted an elastic core retainer cord.

Guard tanks are fitted with air ducts, compressor and trap.

The use of the claimed invention allows to obtain the following technical result.

The design of the panels allows by continuous poddawanie cylinders to vary the degree of tension of the film and to adjust thermal characteristics of the combined coating, to ensure rapid snow melting from the roof of the greenhouse during periods of snowfall, reduce heat loss by 50 to 80%.

Fixing the edges of the film sheets in a removable semi-rigid composite cords with fixation in multiple fixing points in the fixture sockets on the roof of the greenhouses will allow to rise velocity, the quality and reduce the complexity of mounting a film coating on the roof of the greenhouse.

The film Assembly of panels of several film layers, between which are invested translucent polymer cylinders for air, allows you to maintain a film of the cloth taut and will allow us to modify thermal characteristics of roofing.

Delcianna reversibly-deformable shell retainer cord into the Central groove of the main cord and installation in the shell elastic core cord enhances the fixation of the retaining cord.

The proposed fence greenhouse differs from the known, taken as a prototype, the fact that between the layers of film panels installed translucent polymer cylinders for air.

Thus, the proposed solution meets the criteria of the invention of "novelty."

In the patent and scientific literature and other sources not described fence greenhouse between layers of film panels cover installed translucent polymer cylinders for air. Thus, the proposed solution meets the criteria of the invention "inventive step".

The proposed fence greenhouses can be used in agriculture in replicastore, allows to reduce the complexity of the redecoration of the MS film fences on the roof of the greenhouse and the ability to control thermal characteristics of the roof.

Thus, the proposed fence greenhouse satisfies the criteria of the invention "industrial applicability".

The invention is illustrated by drawings, where figure 1 shows a multilayer film guard Assembly;

figure 2 shows the combined polymer cord Assembly with two film panels;

figure 3 shows a variant of the attachment of the combined cord on the roof of the greenhouse and the location of the elements of film panels in position.

The fence greenhouse film contains a panel consisting of the upper film layer 1, the bottom film layer 2 and a few or, for example, one of the first film layer 3. Between every two layers of the film along the edges of the panels are translucent synthetic cylinders 4. To prevent slippage inside the cloth, the cylinder 4 is fixed at the edges of the strips of film 5. Along the very edges of the film panels before installation pave elastic retaining cord 6, which together with the edge of the film fences 7 is inserted in a reversibly-deformable sidewall of the main groove profiled cord 8. In the Central groove of the main cord 8 is a combined retainer cord 9, 10.

A glass enclosure of the greenhouse shown in position 11. Semi-rigid composite cords 12 is fixed to the attachment points 13. Position 4 shows one option of the mount - figure ledge of the window.

The fence greenhouse is assembled as follows.

Originally made combined film panel, consisting, for example, three layers 1, 2, 3. Between layers of a film stack of translucent polymer cylinders 4 fastening strips of film 5.

Made film panel required length deploy at the mounting site, located next to the block of greenhouses. Next stretch semi-rigid composite cords 12 of the same length.

Fixing the edges of the film sheets in a semi-rigid composite cords 12 by snap (indentation) elastic retaining cord 6 together with the edge of the film sheets 7 in reversibly-deformable sidewall of the main groove profiled cord 8.

To enhance fixation of the retaining cord 6 in the Central groove of the main cord 8 wilkepedia combined retainer cord 9, 10.

Fixing the cord is made of a composite. Originally wilkepedia reversibly-deformable sheath of the cord 9, which is then inserted elastic core 10.

Several stacked film panels manually or using a rope stretched between two moving lifts, to which hung a combination of cords 12 are fixed in their film, and move at ladywood along the entire length of the greenhouse migration, on the roof of the greenhouse on top of the glass enclosures 11. Semi-rigid composite cords 12 is stretched and fixed on the roof a few attachment points 13. One of the options of the mount - opening from below the window with shaped protrusion 14, upon closing of the clamping and locking profile in the shape protrusion of the mount 13. Translucent synthetic 4 cylinders attached to the duct system and cheat, pulling the upper film layer and creating an air gap between the other film layers. The air in the duct system is continuously pumped by the compressor to compensate for the pressure reduction through minor injuries polymer cylinders and defects jumpers. Excess air from the system continuously discharged through a water seal. Regulation of the water level in the water seal allows you to adjust the air pressure inside the cylinders and, consequently, the degree of tension of the film coating. When snowfall pressure drop of the snow cover exceeds the air pressure in the system and presses the upper film layer to the glass enclosure 11 of the roof of the greenhouse, the heat-shielding air layer disappear and the conditions for rapid melting of snow. After melting snow of the air gap between the film layers 1, 2, 3 under the pressure of the charge air restore the flow, restoring high heat-shielding properties of the coating.
