How to make a greenhouse with your own hands from rebar: requirements for materials and structures

Wanting to speed up the start of the harvest process, summer residents are taken for arrangement greenhouses in their area. Greenhouse facilities can be made of various materials, while having different sizes and shapes.

One of the most common options - greenhouse of the armature. This is a simple construction.does not require large material investments. How to make a greenhouse from the fittings with your own hands, consider below.

Types and design features

Reinforced greenhouse facilities can be divided into two types:

• steel greenhouse;
• plastic greenhouse (composite reinforcement).

Both of these designs have almost the same pros and cons. Benefits include following indicators:

• simple and quick installation of the frame;
• the ability to quickly disassemble the structure if necessary;
• acceptable cost of materials.

Design flaws:

• long fittings are inconvenient to store;
• plastic fittings are more suitable for the construction of small structures;
• metal fittings tend to rust, and therefore need to be periodically treated with a primer.

Coating Materials

To cover reinforcing cage using film, polymer, cellular plastic. Relatively recently, polycarbonate honeycomb appeared on sale, which summer residents began to use as a substitute for glass.

Advantages of polycarbonate:

• high ability to transmit sunlight;
• resistance to mechanical damage;
• polycarbonate greenhouse life is about 20 years;
• resistance to moisture and water.

disadvantages:

• polycarbonate is combustible and melts when exposed to open flame;
• It has a high cost, unlike other materials.

There are several types of film used for the construction of the greenhouse:

1. Unstabilized film. Capable of transmitting up to 80% of sunlight. The disadvantage of this coating is a small margin of safety, as a result of which the film must be changed from season to season.
2. Transparent hydrophilic membrane. Differs in the increased durability, crash-worthiness and elasticity, and also vapor permeability. The main advantage of this material is that condensate drops do not fall from above, but flow down the coating, which favors plant growth. The material retains well the heat accumulated during the day.
3. Heat-retaining polyethylene. Increases the temperature inside the building by 1-3 degrees, keeping it. The service life of the material is about 9 months. The yield with such a coating is 20-30% more than with other types of film. The lack of heat-retaining polyethylene is relatively low strength.



4. Reinforced polyethylene. This material is practically not torn, which allows it to be used for two seasons. The downside is the low conductivity of light.
5. Polyvinyl chloride film - the most resistant to climate change and external damage. Service life is up to 6 years.

Note: since the greenhouse is made of steel reinforcement is a more stable and robust design, attention will be paid to this very structure equipped with a film coating.

The foundation for the greenhouse

Greenhouse frame of steel reinforcement requires the construction of the foundation. Such the design differs in big weighttherefore, the reinforcement loose in the concrete will gradually “sink into the soil”.

For the reinforcement of the foundation use rods with a diameter of 12 mmthe frame itself can be made of thinner reinforcement - with a cross section of 8 mm.

For heavy-weight reinforcement cage, it is necessary to build a strip footing. Optimum design dimensions:

• depth 0.5-0.8 m;
• width - at least 20 cm.

In the northern regions, the foundation is laid to the depth of soil freezing. Besides he needs warming through trench fragments of foam.

Approximate option of the base:

The process of building the foundation for the greenhouse of the valves with their own hands:

1. Trench is being dug required depth and width. When marking the perimeter, you should align it diagonally, then install the stakes in the corners.
2. Formwork is being constructedwhose height should be from 10 to 15 cm. For its manufacture, you can use boards with a thickness of 25 mm, chipboard, plywood. Top formwork must be leveled with a level.
3. The reinforcement mesh of reinforcement is being prepared.
4. Fitted reinforcing mesh.
5. In the trench are installed in advance prepared frame sections.
6. Concrete is poured in several layers (thickness of each layer is 15-20 cm). Each layer must be compacted to avoid the formation of voids. Do not lay stones in the trench or crushed brick - this will adversely affect the strength of the foundation.

Manufacturing frame

For robust and durable construction bars of reinforcement is better to weld with each other, but it is also possible to use knitting wire. So that the assembly does not cause unnecessary difficulties, the framework is constructed outside the trench.

He is construction in the form of arches of reinforcementinstalled at a certain distance from each other and fastened together by horizontal rods.
The number of rods due to the depth of the foundation, as the bottom construction needs a high-quality reinforcement.

First of all, arches are made of reinforcing bars, taking into account the height of the future structure and the depth of the foundation. Next, the finished parts are installed in a trench and welded to each other by means of horizontal crossbars. The distance between the arches is 0.4-0.5 m.

Possible frame option:

Note: it is necessary that the arches are located in the middle of the width of the foundation tape.

Fixing the film to the metal frame

For fastening steel frame films are basically use two ways.

1. Method using clips. Many options of greenhouses, commercially available, are equipped with special clamps. When building a greenhouse on its own, you can make these parts yourself.Clips are made of bent sheet steel.

   When fixing mounts rubber pads must be used, thanks to which the film will last longer. Gaskets will protect the coating from contact with metal clips.

Ready clamps as sample:





2. For fixing film coating can also use a large mesh mesh, which is stretched outside and inside the greenhouse structure. Thus, the material will be tightly fixed between the two mesh layers.

Steel reinforcement structures with film coating - odin of the most reliable and effective methods greenhouses. In addition, the strength and durability of the iron frame will not make you regret the choice made by fans of agriculture.
