As you know, Central Russia — a zone of risky agriculture. The late spring frosts, the “acid” summer rains, early autumn cold… in short, without a greenhouse on the plot is not enough. Otherwise they will not ripen there no cucumbers, no tomatoes. Of course, if we are talking about the same bed under the film is a small problem. Now in stores you can buy a set of parts of a light metal frame, assemble it, cover with film and the greenhouse is ready! Another thing, if you want to make the greenhouse more — it will require the construction of a strong metal or wooden structures, and eventually the construction will cost the farmer a pretty penny.
However, to make the greenhouse, it is not necessary to use traditional construction methods. We offer you to apply for this experience in the production of tent structures. Such structures are extremely economical: in the simplest case with a single rack and a dozen stretch marks can cover hundreds of square meters.
Before you two greenhouse type tent. First — with one Central and four peripheral columns. They can be made of any suitable material — the wooden stakes or poles, steel or asbestos cement pipe. Under each of the stands will need to build a simple Foundation. To do this, just choose to manually drill the hole with a diameter of 0.35 m and a depth of 0.7—0.8 m, lay in her rolled steel roofing and fill this makeshift formwork concrete mixture. Until the concrete has hardened, it lay the reinforcing rod so that the surface was about 100 mm — it will lock when installing the racks.
The same base line anchors are laid in places where they will be fixed backstay of the tent greenhouses. The only difference is that instead of the reinforcing rod laid in the concrete loop of steel wire with a diameter of about 6 mm.
On the upper parts of racks is necessary to provide eyelets for attaching braces on the uprights of steel tubes to weld the brackets of the reinforcing rod with a diameter of 8 mm and easier to drill a few holes. For wood or cement stands will have to make yoke from a steel strip welded thereto brackets of the reinforcing rod.
