RU359U1 - Frame greenhouse - Google Patents

Abstract

1. A greenhouse is a film frame, including a metal frame and a film coating, characterized in that the arches are made with a constant radius of curvature and the center of curvature is located above the base of the greenhouse, which ensures uniform distribution of the stress loads of the film coatings and reliable fixing of the film parts of the end part of the greenhouse. 2. A greenhouse according to claim 1, characterized in that the film coating details of the surface of the greenhouse, equipped with tension cords, are superimposed sequentially on two adjacent arches, starting from the first and second, and stretched by cords from the outer sides of the arches. 3. A greenhouse according to claim 1, characterized in that the useful area of the greenhouse can change (increase, decrease) by changing the number of arches, longitudinal ties and details of the film coating without changing the design as a whole.

Description

Utility Model Description

Greenhouse film, frame refers to a device for

growing vegetables in the spring and summer in individual garden plots

Known film frame greenhouses A.C./i 1672987 AI, A.S. No. 1625428 AI.

The disadvantages of these greenhouses are the complexity of the manufacture, installation and fastening of film coatings. Their designs are acceptable for large greenhouse complexes

The task of developing the proposed utility model is to create a greenhouse for individual garden users, which is simply mounted, the film coating is easily and evenly stretched, firmly fixed.

This problem is solved by the design of the frame of the greenhouse and the film coating. The frame of the greenhouse (Fig, 1, Fig, 2) is made of pipes or of bent profiles and consists of arches I, fastened together longitudinally1 and by ties 2, doors and ventilation windows. Arches have a constant radius of curvature with a center Bjier than the base of the greenhouse, forming a barrel-shaped surface. For ease of transportation, arches are made in three-piece prefabricated. The lower parts of the arches have support plates with which the arches are attached to the base, they also have loops for tension cords 4,

The details of the film coating 3 are made with tension cords 4, with which they are stretched and fixed on the frame.

Arches I are installed on wooden blocks or a light foundation with embedded wooden inserts, the base plates are fastened with nails, the arches are interlinked with each other by means of ties 2, the latter ensure the accuracy of the installation step. Doors and vents are installed in the end arches

The tension of the film coating begins with the end arches) Fig, 2) A film part is superimposed on the arch of the arch and the near pillar of the doorway with tensioned VI cords 5, the edges are bent around the frame pipes into the inside of the greenhouse, the cords are evenly stretched and connected. The curvature of the arches does not allow the film coating to move from the installation site. The surface of the greenhouse is covered with parts 3, which are made

from a single film sleeve (stocking). Stretch cords 4 are missing on both edges of the part.

The film part 3 is superimposed sequentially on two adjacent arches, starting with the first and second and bends around them from ground to ground. The edges of the film part extend beyond the outer sides of the arches, the free ends of the cords 4 are led into the corresponding loops on the supporting plates of the arches. After that, the cords are evenly stretched and fixed. Since the radius of curvature of the arches is constant, when the cords are tensioned, radial forces are formed that uniformly stretch the film over the entire surface. Subsequent parts are laid and stretched in the same way, with one edge of the film coating 3 of Fig. 3 being applied to the film coating of the previous pair of arches and the tension of the cord pulls up its residual slack.

The film parts of doors and vents also have tension cords, are superimposed respectively on the frames and are pulled inward by cords.

It can be seen from the foregoing that the utility model consists of standardized parts that are easy to manufacture, easy to assemble and assemble. This allows you to highlight another design property: by changing the number of arches I, respectively, longitudinal ties 2 and film parts 3, you can change (increase, decrease) the useful area of the greenhouse. Those. the consumer can order (produce) a greenhouse of the required usable area, and if necessary, upgrade the existing one.
