Construction of greenhouses

The greenhouse, like a greenhouse, has a frame and a transparent “casing”, however, the similarity ends. Unlike greenhouses, greenhouses allow you to take care of plants all year round, supporting the conditions necessary for them. They are often equipped with very complex ventilation, watering and lighting systems, therefore they require a certain design period in which they proceed from the environment and requirements for the cultivation of plant species that will be grown in it.

The constructive part of the greenhouse

The greenhouse can be both stationary and figurative, collected as a designer as needed. As a rule, these are frame -type frame structures with polyethylene coated or more durable plastic: acrylic, plexiglass, polycarbonate. Such a greenhouse can have a complex engineering structure, taking into account all the requirements for ventilation and even heating, but at the same time it is easy to understand and be transferred to a new place.

The internal space of the greenhouse is organized either according to the rack or soil type. In other words, plants can be grown “on a shelf” or as usual on the ground. The first type allows you to increase the volume of manufactured products on the same area. Shelves can be removable and go into several rows. The main thing is to provide proper watering and ventilation of such beds.

Materials for frame greenhouses can be both steel and plastic, or wood. Metal frames are certainly reliable, but the high thermal conductivity of the metal makes you take care of the additional thermal insulation of this design. The transparent “dome” is made from the “double -glazed window” at the basis of which lies both simple thick glass and modern plastics. In the case of natural glass, it is necessary to calculate the strength of the structure, t. To. its weight does not allow the use of lightweight options. Organ -glass and polycarbonate are more democratic in weight and less fragile, but they are less transparent, which means they miss less light, which is not suitable for all plants. In each case, a compromise is needed.

The construction of the greenhouse

Choose a place for your greenhouse. It should be near water sources, and groundwater level should not increase humidity in the room. Try not to put it in blown and “cold” areas. Take into account shading by surrounding buildings and plants.

If you plan to put a temporary version of the greenhouse, then place it from north to south. This will allow you to warm and ventilate the room more efficiently. The stationary structure is better to place from east to west. Then you can avoid overheating in the summer.

For a light frame structure, a wooden beam with a cross section of 50×50, a rail, a wire material, often just a film and a brick for the arrangement of the “foundation” are required.

At the site of future construction, a design plan is drawn. Install corner and intermediate supports, digging them into the ground to a depth of 50-60 cm. To protect the tree before lifting it, you can wrap it with a piece of roofing material or previously bury a piece of steel pipe of the desired diameter, and the beam is scored into it.

Before arranging the lower strapping, a series of brick is laid around the perimeter. This will avoid drafts in the room. The upper strapping is installed with simultaneous puffs for the flat “roof”. For the formation of a slope, standard rafter farms with legs tights are collected.

Film laying is carried out from the back wall to the entrance. It is advisable to use whole pieces of polyethylene. Reiki and small nails are used to fix it.
