Greenhouses with arcs with cover material: Leroy Merlin, greenhouse greenhouses with their own hands, how to fix and make

Hotbeds of arcs with covering materials - light and simple design In much of Russia the cold days, on average, more than warm, but various designs in the form of a greenhouse or a greenhouse allows you to harvest. The greenhouse, unlike the greenhouse, has relatively small dimensions and is used seasonally. To protect the seedlings from unfavorable weather conditions, as well as to increase the vegetation period, a portable greenhouse consisting of arcs with cover material is suitable. We will discuss what constructions are and how to assemble them.

Stainless arc for greenhouse

The design will not be degradable unlike a tree. The greenhouse of the arches has light weight and will be easily transported and folded. Such an arched greenhouse can be made with your own hands of absolutely different length and height.

Hotbeds with arched materials have a number of advantages:

• Economical design;
• Durability;
• Hygiene;
• Practicality.

In many gardening shops are commercially arc piece in the set, the arc constituting the frame, sewn in the form of an accordion, as well as a kit with film for the whole assembly of the greenhouse.

arcs for the greenhouse may be made of different material

arcs for the greenhouse may be made of plastic, metal or PVC.

The cheapest arcs stand on average from 40 rubles( from PVC).In Leroy Merlin( there is a photo and video catalog) plastic arcs for a greenhouse cost from 25 rubles per 1 pc. If you select the arcs with the film, then an average of 500 rubles, but the price range may differ, depending on the region, as well as the size of the structure. To avoid the calculations of all components of the greenhouse, you can use a set consisting of arcs, which consist of metal tubes covered in a polymer shell, connecting elements made of plastic. Such collapsible sets of greenhouses can be from 2 m to 4 m. Before acquiring arcs and covering material, it is necessary to measure the dimensions of the beds. Also, it is necessary to take into account the height of the future framework, depending on the height of the plant.

Mounting options arcs Greenhouse

To start the consolidation arcs, choose a place in the future greenhouse, it should be well lit( the sunny side), windless place. If you choose a naked, windy place, then the hotbed can simply be torn or tipped, then strong wind gusts can damage the seedlings, which will reduce the yield.

It is necessary to consider:

• Arc height;
• The higher the greenhouse, the better it needs to be fixed;
• Burying, as much as possible, strengthens strength.

The fastening of the greenhouse arcs can be done in several ways

How to make arcs for the greenhouse with your own hands

All gardeners and amateur gardeners try to reduce the cost of growing as much as possible, and get more benefits and benefits from their ownVegetables and, probably, flowers. You can avoid buying arcs for the greenhouse and ready-made structures, using your own ideas. Wooden arcs or arcs from tree branches - the selected material must be joined together with nails to resemble an arch.

Tree branches:

• Must look like a billet under the fishing rod;
• Do not remove the bark;
• No need to dry the branch;
• Thin can break off.

You can make the arches for the greenhouse yourself

We put the entire assembled structure as deep as possible into the soil and bind the covering material. If we produce a wooden frame, the resulting greenhouses will be straight-walled. The frame made of polypropylene water pipes, if any, can easily be assembled, connecting all parts with couplings, elbows, tees, and plastic corners.

The covering material is fixed to the pipes using polypropylene pipe fastening or film clips.

Popular and rigid frame( wire), however this design will be only 0.5 m and is suitable only for seedlings in the greenhouse.

Sturdy metal arcs for the greenhouse

Metal arcs are the strongest for large greenhouse dimensions, however, in order to assemble the entire structure, you need a welding equipment, or drilling holes for a bolted connection. For the frame of the greenhouse, galvanized profile pipes can be used, which can last up to 20 years.

Nuances:

1. For cutting a metal profile a Bulgarian is used.
2. After drilling holes for fastening, trimming damages the galvanized profile layer.
3. In drilled areas, it must be treated with cold zinc.
4. Cold zinc will protect the metal profiles from corrosion, which will increase the service life.

Metal arcs are the most robust for greenhouses

The galvanized profile can be welded together. This is the most rational way to connect all the elements of the greenhouse.

Welding is better than using a large number of bolts, rivets, self-tapping screws.

Welding the galvanized coating is damaged, and the joints must be treated with a metal brush and apply cold zinc.

Ways: how to calculate the arc length for a greenhouse

Before building a greenhouse, it is necessary to measure the bed with an electronic or manual meter, and also to determine the height, depending on the height of the seedling. For the greenhouse drawing, you need to define the width, din and height.

The width must be greater than the width of the bed by 30 cm.

Depending on the size of the greenhouse, sections on the facade are identified, that is, the number of arcs. The arc length is calculated using the Huygens formula:

p ≈ 2l + 1/3( 2l-L)

The required number of arcs for the greenhouse can be calculated using the formula

Where:

• p - arc length;
• l is the chord from the point of connection of the greenhouse with the soil to the top point on the "roof" of the greenhouse in the middle;
• L is the length from the point of connection of the greenhouse with the soil to the point of connection of the greenhouse with the soil lying in parallel.

Calculations on the dimensions of the greenhouse can be made using an online calculator, entering data. If the greenhouse is installed inside the greenhouse and has small dimensions, then you can use a simple meter, and avoid a complicated calculation.

Clamps for the arcs of the greenhouse

The selected covering material is clamped, they can be double or normal, to the arches, depending on its diameter. Before you buy clips for arcs, you need to decide on the cover material.

Greenhouse covering materials can be:

• Polyethylene film on roll;
• Polyethylene film perforated black;
• Polyethylene packed film;
• Polyethylene green reinforced film;
• Cover material Spunbond;
• Grid from birds;
• PVC film;
• Cover for roses and shrubs.

Before you buy the clamps for arcs, you need to determine the cover material

For the best possible fastening of the covering material to the greenhouse, special pegs are used, they are attached to the frame of the hotbed. A high greenhouse called "Rainbow" consists of galvanized pipes and polycarbonate sheets, and has positive feedback from gardeners and gardeners of amateurs.

Polycarbonate cover material is used for a more robust construction for the greenhouse.

Since the polycarbonate weighs much more than the film, the frame must be as stiff as possible and stronger, for this we choose a galvanized profile or from a profile pipe.

Optimal distance between arcs of a greenhouse made of polycarbonate

A frame made of a closed rectangular profile can withstand snow, rain and wind, but its cross-section must be 25x25 mm or 30x30 mm. For structural stability, it is necessary to pay attention to the wall thickness of the profile, it should be 1.5 mm or more. The metal profile itself should be made cold-rolled, as it will be resistant to corrosion. The greenhouse is a special place where high humidity, if you use iron profiles without galvanized coating and made in a hot-rolled way, then just a couple of weeks will be covered with rust. In order to avoid these problems, for lack of a high-quality profile, the usual iron profile must be covered with paintwork material. In the field, a powder-polymer paint is good, it is resistant to damage, such as scratches, chips.

Special attention must be paid to the distance between the arcs of the greenhouse. To distribute the load to the entire structure with polycarbonate cover material, the arcs are located at a distance of not more than 1 meter from each other. You can also take into account that the more often you place arcs, the stronger the frame for the greenhouse. Also, the arcs must be integral, do not understand, if they are understood, this reduces the strength of the structure. If there is a large number of horizontal bridges in the greenhouse frame( additional steel connecting elements), this also reduces the strength of the structure due to stress concentration, such a design is not reinforced.

Arcs for greenhouse should be located at a distance of not more than 1 meter from each other.

Polycarbonate covering material should be 4 mm thick with a density of at least 700 g / m2.

Polycarbonate density is very important, because the higher the density, the greater the load polycarbonate can withstand, and most importantly, the higher its thermal insulation characteristics. Also, polycarbonate should have a fire certificate, UV protection.

UV protection is required for polycarbonate because it:

• Vulnerable to sunlight;
• Its structure is changing;
• Properties are lost;
• Further it becomes fragile;
• May burst from simple rain or hail.

When assembling a greenhouse, it is necessary to take into account its ventilation, or partial dismantling. If you make airing in the greenhouse, then the windows are made at the top or on its roof, this helps ensure that clean and cool air is mixed, and compared with the temperature in the greenhouse. If the pane is installed at the bottom of the hotbed, the warm air will remain above, and the cold will not mix, but freeze the seedlings. However, the greenhouse is needed in the most seasonal way, during the spring, when only the snow has fallen, and as a rule make structures that can be disassembled, and allow the plant to grow in the open ground.

Before building a greenhouse, consider its orientation in the villa area. The most optimal option, where to install a greenhouse, is the orientation of the greenhouses from south to north, this will catch the seedlings morning and evening rays of the sun. The height of the greenhouse is calculated, depending on the type of plant grown. Collect your greenhouse and set it on beds, and this year will be harvest. Examples
