In the “M-K” No. 8 for 1984, we talked about the greenhouse arch designs made by students of the Bauman district of Moscow. Its main load-bearing elements — the half-arches — been made of gymnastic hoops. This circumstance is strictly determined size of the greenhouse. But it is tempting to build on the same principle a more spacious and convenient in maintenance construction of a greenhouse. But here’s the problem: the material for poludov frame to find easy.
But Muscovite Mikhail Nikolayevich Simakova managed to find a solution to this problem. In the proposed scheme it is possible to build a greenhouse, not having virtually no metal parts! I hope that this design, it is available for self-repetition, will interest our readers.
The idea to make this greenhouse was inspired by two things at first glance do not have anything in common: industrial arched warehouses-storage and, oddly enough… fishing. The first prompted the idea of the arched structure, the second to use as a carrier poludov flexible vine or shoots of trees (birch, walnut, cherry, etc.) — a whip, often used by fishermen as fishing rods. The result is a cheap and simple construction, it does not have any need of scarce materials or a specially equipped workshop. Hatchet, hammer, saw, auger or drill, a knife, scissors, pliers, and even a soldering iron and a file — that’s all the tools for the job.
The amount of materials needed depends on the chosen size. So, at the height of the greenhouse, 1 m and length 3 m, you will need 15 m2 of polyethylene film, three logs or thick enough pole length 3.5 m, four peg-backup length 1.5 m, one Board on the horse with a length of 3.2 m, four metal bracket or gusset plate, some nails, scraps millimeter of soft wire, four poles along the length of the greenhouse and, finally, twelve flexible rods for bearing poludov length of 1.5 m. If you up the greenhouse in the human height (1.8 m) in length 2 m, you will need three logs Ø 150-200 mm and a length of 2.2 m for the longitudinal connection, three logs of the same diameter with a length of 2.5 m for stake-jacks, ten rods on the half-arches Ø 25-30 mm and a length of 2.9 m. If the sectional construction of the greenhouse, you can continue as far as the size of the site and availability of materials.
