Greenhouses for country garden areas today are not a curiosity. On the contrary, if the variants of greenhouse constructions were previously intended for farming or industrial growing of vegetables, today it is possible to pick up a small greenhouse facility for any placement on the site. How to choose a greenhouse in the form of a finished construction or to build it?
Content
The frame structure of the greenhouses and special fastening points simplify the creation of the shell from the covering material, giving the light a large area of dispersion.
Criteria for choosing greenhouses
The criteria for choosing greenhouses are the types of structural skeletons and shell material, as well as the availability of operational capabilities for dismantling the structure for the winter.
format and types of greenhouse structures
Greenhouses in the format are divided into country, farm and industrial buildings. The criteria for evaluating the format are: the size of the greenhouse and the area of the shell, as well as the material of the coating.
For dacha and homestead greenhouses, the dimensions are:
• length from 4,0 to 5,5 m
• width from 2,8 to 3,2 m
• height from 2.2 to 2.4 m
• shell area from 33 to 47 sq.m.
In addition to the dimensions, it is necessary to take into account the type of frame construction on screw connections made of painted or galvanized pipe.
characteristics of greenhouse frameworks
There are the following types of greenhouse frame: country - arched, one- (Vegetarius) or gable, mitlajdera, pristennaya and pros- Farmer and industrial.
The system of fixing the covering material to film structures is simpler, the polycarbonate frames are fastened using spiders and bolted joints, providing for the installation of automatic window openers.
In addition, useful advice on how to choose a greenhouse has not harmed anyone yet.
arched frames
The arched frame consists of an M-shaped profile of a square or round tube with a cross section of 20x20 mm, a thickness of 1.4 mm forming characteristic arcs with a distance between them of 0.6-1.0 m.
As a coating, a multi-season film or polycarbonate with a thickness of 4-10 mm is used.
The number of doors can be 1-2 with a total of 2-6 ventilations at the ends of the frame.
Helpful Tips
For arched greenhouses are characteristic roofs in the form of an arc, thanks to which the sediments do not stay on the surface. Light diffusion occurs over the entire surface area, allowing penetration into the required amount. In the arch structure of polycarbonate, there is a dependence of the dimensions of height and width, due to the length of the standard sheet (2100 mm). It is more practical to choose the dimensions of the frame, multiples of the width of the sheet, eliminating the waste during installation.
skeletons
Pitched greenhouse frames can be equipped with one slope (Vegetarius) or be gable. When constructing a frame for a greenhouse, a hot-dip galvanized square pipe of 30x30 mm cross section is used, forming rectangular arcs in steps of 0.5 to 2 m. Ramp frames are characterized by wide doors (1 or 2) and 2-4 pylons, located on slopes and ends .
Helpful Tips
The structure of pitched greenhouses is distinguished by a good useful area for growing plants. Even plants planted near the side walls grow up unhindered. However, it does not hurt to remember that the one-run greenhouse has the lowest degree of illumination. It is recommended not to build a greenhouse of a polycarbonate polycarbonate, because a high side with a significant wind load causes sail, leading to deformation of the structure.
wireframe
Mitlajder's greenhouse frame is equipped with a hot-dip galvanized pipe with a square section of 30x30 mm, which form arcs of rectangular shape with a distance of 1-2 m. Polycarbonate sheet thickness of 4-10 mm is preferred as a cover, which is used simultaneously for door and window leaves. The number of windows on the frame can be up to 8 pieces.
Helpful Tips
The traditional design of the mitlajdera gable roof consists of vertical walls. However, the most popular option is based on an arched framework covered with a film. Such a greenhouse made of a film can be built with its own hand, providing for the width of the passage for one person and the creation of two beds with a distance between them up to 700 mm.
greenhouse film
The greenhouse film is made from high-pressure polyethylene, using ultraviolet stabilizers, antifogs, infrared absorbents and light-scattering additives. Therefore, we choose the film correctly, providing for its multi-season operation and individual needs.
Let us say that detailed information on the parameters of antifogs, preventing condensate formation and fogging, as well as absorbents that enhance the greenhouse effect, is included in the commodity certificate.
wall frame
The wall frame of the greenhouse is assembled from a hot-dip galvanized profile section 30x30 mm, which is intended for fixing a standard sheet of polycarbonate. The wall greenhouse is equipped with 1 door with a maximum number of windows. The area of illumination at the wall frames of the greenhouses is the lowest.
farm and industrial frameworks
For the skeletons of professional greenhouses for farming (large and small) and for industrial use, use a square pipe section of 30x30 mm or a round pipe section 52-60 mm coated with anticorrosive enamel.
If necessary, the frames are reinforced and made double.
For the shell used a lot of seasonal film in 2-3 layers or polycarbonate sheet.
In practice, the most popular are considered arched greenhouses in the section of polycarbonate in size for a standard sheet.
polycarbonate sheet
Polycarbonate for sheltering greenhouses has proved itself well. Recall that the performance characteristics of the material is different:
• light transmission up to 85%
• UV protection
• resistance to herbicides and pesticides
• good load-bearing capacity and impact resistance
• operating temperature range from minus 50 to plus 120 °
• service life 10-15 years.
All these factors allow you to choose and buy polycarbonate.
How to choose a greenhouse made of polycarbonate is shown in this video.
We will suggest that before choosing the type of frame of the greenhouse, it is necessary to determine the place of its placement and installation, which will justify the dimensions of the frame.
