Description

The utility model relates to the field of agriculture and is intended for growing early crops indoors.

A known collapsible greenhouse containing a support frame with a translucent coating fixed to it, made with tubular arches successively placed one after the other and connected to them by means of fastening nodes of connecting elements (see RF Utility Model Patent No. 91800, IPC A01G 9 / 14, publication 03/10/2010).

Known greenhouse containing the frame and mounted on the frame translucent film coating. The upper run consists of two symmetrically mounted ridge bars of a rectangular profile, fastened by a side surface to each other with the possibility of their connection. The arched element is made of two arcuate bars symmetrically located relative to the longitudinal plane of symmetry of the greenhouse (see RF Patent No. 2194383, IPC A01G 9/14, E04H 15/36, publication December 20, 2002).

The closest analogue of the claimed utility model is a greenhouse containing a film coating, a frame made in the form of a polyhedron, end walls having frames glazed or coated with a film are presented as polygons inscribed in a circle or oval. The end walls are interconnected by girders, which, depending on the length of the greenhouse or the stiffness of the angular profile, are reinforced from deflection by intermediate arches. On the front end wall there is a door frame, on the back there is an opening for ventilation, girder mounting brackets are welded to the vertices of the polygon corners on the inside of the greenhouse, brackets for fastening film panels are fixed on the two lower girders (see RF Patent for Invention No. 2204238, IPC A01G 9 / 14, publication 05/20/2003), taken as a prototype.

The main disadvantage of analogues and prototype is the lack of rigidity of the structures of the frames, a complex and unreliable system for attaching a translucent coating to the frame.

The task to which the claimed utility model is directed is to improve the quality and simplify the assembly and installation of the greenhouse frame and fasten the translucent coating.

The technical result achieved during the implementation of the claimed utility model consists in increasing the strength of the greenhouse and the reliability of fastening the translucent coating, using convex shapes periodically repeating along its length due to the use of curved elements, arched parts of trusses and arched structures during installation of the frame.

The specified technical result is achieved by the fact that in the film greenhouse, containing a translucent coating, a metal frame, including end walls with doors and intermediate arches connected by girders, according to a utility model, the metal frame is made of sections that are three-dimensional through arches, consisting of flat arcuate trusses with curvature of variable radius, interconnected by runs in the form of curved arches and frame trusses, consisting of curved upper belts and lower rectilinear belts, and to The back sections of the flat arc-shaped trusses in the lower supporting parts are interconnected by flat frame structures in the form of rectangles, and the flat arc-shaped trusses with their ends are supported and fixed on the anchor anchors anchored into the ground, while the metal frame assembly forms a structure in the form of a tent with periodically repeating along the length of the body, the bulges in the roof at the places where the translucent coating fits to the curved elements of the metal frame and hollows in the form of gutters in the spaces m Between the bulges at the joints between adjacent sections, which serve as lodges for laying cables holding the translucent coating on the metal frame and, at the same time, with gutters for collecting and draining precipitation.

Figure 1 shows a film greenhouse, for the assembly of which parts and assemblies are used made of cold-rolled galvanized sheet steel with a rectangular section.

The greenhouse film contains a metal prefabricated frame 1 and a translucent coating 2 of a plastic film or Lutrasil.

The metal frame 1 is assembled from sections - extreme 3 and intermediate 4, which are volume through arches, consisting of flat arc-shaped trusses 5 with curvature of variable radius, interconnected sequentially at regular intervals by runs in the form of curved arcs 6 and frame trusses 7 with a curved upper belt 8, and the end sections of flat arcuate trusses 5 in the lower supporting parts are interconnected by flat rectangular frame structures 9, giving additional longitudinal rigidity to sections 3, 4 and This greenhouse film as a whole.

The end walls of the outer sections 3 of the metal frame 1 are equipped with an entrance gate 10 and doors 11. Flat arcuate trusses 5 rest with their ends on anchor-anchors 12 embedded in the ground and are fixed to them by means of flange connection 13 by fixing means 14.

The utility model is as follows.

The film greenhouse is assembled from the assembly of the metal frame 1, starting from the front extreme section 3. The anchor-anchors 11, which serve as the bases on which the flat arcuate trusses 5 of the metal frame 1 are mounted and are fastened with flange connections 13, are aligned under the level and ground up; (Fig.6).

Between the flat arc-shaped trusses 5 in the lower supporting part they are installed frame structures 9 and are fixed to them by fastening means 13 (Fig.6 and Fig.7). At certain intervals between the flat arc-shaped trusses 5, alternately curved arcs 6, frame trusses 7 are installed and fixed by fixing means 14 (Fig. 8 and Fig. 9).

To the front end section 3 assembled in the form of a volumetric through arch, intermediate sections 4 are attached in the same order, and then the rear end section 3, thus adjusting the length of the metal frame to the required dimensions. In addition, it is possible to increase the size of the metal frame 1 in width.

To do this, flat arc-shaped trusses 5 in the upper part have connectors on bolted connections (not shown in the drawing), with the help of which, flat arc-shaped trusses 5 can be divided into two parts, extend them up to five meters wide, and mount a special insert in the gap formed (not shown), bringing the total width of the flat arc-shaped trusses 5 and, accordingly, the width of the metal prefabricated frame 1.0 to 12.6 meters.

Complete the assembly of the metal frame 1 by installing on the extreme sections of the entrance gate 10 and doors 11. From above and from the ends, the metal prefabricated frame 1 is covered with a plastic film or Lutrasil, forming a translucent coating 2 in the form of a tent having a periodically repeating convexity of the shape of the roofing in the places where the translucent coating fits 2 to the curved arcs 6 and the curved upper belts 8 of the frame trusses 7, and the flat shape of the wall part from the ends and in the places where the translucent coating 2 fits to the elements of flat straight lines coal frame structures 9.

At the same time, the film depressions formed across the greenhouse in the translucent coating 2 in the intervals between the bulges at the joints between sections 3 and 4 serve as a lodgement for laying a cable (not shown in the drawing) that holds a plastic film or Lutrasil on the metal frame of the panel and at the same time a drain trough precipitation.

Weights suspended at both ends of the cables (not shown in the drawing) ensure their uniform tension. The free edges of the panels of a plastic film or Lutrasil hanging from the top of the greenhouse roof to the ground on either side are dug up with soil or pressed with sleeves filled with sand (not shown in the drawing).

This form of translucent coating 2 and the method of attachment allows you to securely hold it on a metal frame 1 and, very importantly, prevents the "clapping" of the plastic film panels in strong winds in bad weather.

If necessary, an additional heat-insulating translucent or shading layer (not shown) is used to fix the plastic film or Lutrasil lower belts of flat arc-shaped trusses 5 and lower rectilinear belts of trusses 7 on the inner side of the metal frame 1.

Using the proposed film greenhouse will improve the quality and simplification of the assembly and installation of metal frames. Because of this, the operational capabilities of using a film greenhouse are expanding, increasing the rigidity, strength and lightness of the design of the metal frame of the greenhouse, improving the reliability of fastening the translucent coating.

The proposed utility model can find application in the cultivation of vegetables and other crops, for example, in private horticultural plots, as well as in large-scale farms.
