The main part of any greenhouse or greenhouse - frame.
Its strength provides ease of use of the structure and its durability.
It is made of wood and plastic, but metal is the most reliable solution.
Consider the features of the arrangement of the greenhouse of the profile pipe and the technology of its construction with your own hands.
Characteristic design
Building a greenhouse from a profile pipe does not require technical knowledge or the use of a professional tool. Gardener can choose the appropriate form of construction.
For the frame of the greenhouse is used two types of shaped tubes:
40х20 mm - frame frames;
20x20 mm - connecting bridges between frames.
In the case of the construction of an arched greenhouse, the purchase of ready-made elements is recommended.
To bend the profile pipe is used special expensive tool - pipe bender.
But it will never justify its price if it is used once during the construction of the greenhouse. Only gable greenhouses with straight walls are erected with their own hands.
The popularity of structures from the profile pipe due to the fact that to fasten sheets of polycarbonate - the base of the shelter profile greenhouses - many times easierthan round tubes. Yes, and the frame of galvanized pipe profile will last longer than any similar material.
The structure of the greenhouse of the profile pipe includes a frame and covering material. It depends on the frame strength and reliability of the finished structure. The framework in turn consists of three parts:
- lower strapping;
- top strapping;
- arc.
What is grown?
Greenhouse can be stationary or temporary, respectively, with the foundation and without it. Stationary greenhouses are used for growing seedlings and decorative flowerswhereas temporary constructions protect plants from sudden changes in temperature air and late frosts. Profile pipes are more often used for arranging year-round greenhouses.
The stationary greenhouse construction is often used for growing seasonal vegetables and greens. For example, cucumbers, peppers and stunted tomatoes. Experienced gardeners are experimenting with the cultivation of zucchini, pumpkin and eggplant.
Advantages and disadvantages
Greenhouse cultivation has its pros and cons. Among the main merits select:
- The possibility of extending the planting season. Planting is carried out earlier than in open ground, and therefore the stage of ripening comes earlier, leaving gardeners time to repeat the planting cycle.
- Greenhouse construction will protect from bad weather conditions in the form of heavy rain, wind or frost, which can harm plants.
- Save pest control - in a closed "room" there is no access to birds and flying insects.
- Observed saving planting material. In a greenhouse, conditions are created that are as close to ideal as possible for high-quality plant cultivation. This ensures almost 100% germination of all seeds and rooting cuttings.
- Opportunity control the growing process from the beginning to the end due to manually changing the basic parameters of the greenhouse microclimate: humidity and air temperature.
- The construction of the profile tubes stand for longIt is wear resistant. You can forget about repairing a greenhouse or replacing basic elements for a long time.
When there are positive sides, there will definitely be limitations:
- There is a risk of overheating in the greenhouse. Without proper ventilation on a hot summer day, plants receive an excessive amount of light and heat, which negatively affects their condition.
The need to control the amount of moisture inside. Both excess and lack of moisture will negatively affect the condition of the plants. - We will have to spend time and money on proper care and maintenance of the greenhouse. Purchase of materials for construction, regular watering and heating, cleaning, replacing the soil - all this costs money and takes time.
Greenhouse from the profile pipe
Doing a small greenhouse with your own hands is not so difficult. Requires a small knowledge of plumbing and the ability to work with welding.
There are several highlights that need to be considered when building a greenhouse structure from a shaped pipe.
Choosing covering material
There are 4 main types of covering materials on the market:
- Glass - enjoys high popularity due to its high protective properties. A glazed greenhouse will protect the planting from frost, letting the sunlight through and retaining heat. Cons of the material: high cost, installation complexity and low strength.
- Polyethylene - available material, now rarely used because of its low strength and damage under direct sunlight.
- Nonwoven fabric - well passes light and water, providing to landings protection against negative weather factors. Cons: fragility. For example, a spanbond or lutarsil will serve as a greenhouse shelter for no more than 5 years. Their strength is also not too high, the shelter may break during a strong wind or under the weight of a layer of snow.
- Polycarbonate - solid polymer, characterized by high strength with low weight. Provides a greenhouse a number of thermal insulation characteristics due to good dispersion of sunlight. Working with polycarbonate is easy, so it is often used to create greenhouses with your own hands.
How to make the frame strong?
If the profile pipe originally used to create the framework was not protected from aggressive environmental influences, it will be necessary to take care of it during the construction phase.
It is enough to purchase in specialized stores one of the tools that provide the frame protection against corrosion processes. The latter often lead to damage to the entire structure.
Preparation of drawings
This figure shows the greenhouse drawings of the profile pipe with possible sizes.
Before you start building a greenhouse, you need to make a drawing, decide on the type of construction, take measurements, on the basis of which the project will be created.
Instructions for the construction of a greenhouse from the profile pipe
Under the greenhouse of the profile pipe can be laid light foundation, which will protect from the flow of cold air from the outside, or capital (poured concrete). In the second case, pre-made mortgages with the aim of attaching further metal racks.
The profile pipe is cut into pieces with a dimension corresponding to the design.
For arched greenhouse will need arc. If we are talking about shaped pipes, you can bend them in an arc using a concrete ring.
How to bend the pipe in an arc using a homemade pipe bender, you can look at this video:
The profile is cut the required number of vertical racks with a length of 65 centimeters. Arcs will be fixed on them.
IMPORTANT! If you want to install a collapsible greenhouse, then use bolts at the junction of arcs and racks. Otherwise, you need to select welding.
After fixing the arcs in the racks, it is necessary to make the greenhouse doors from the profile according to previously taken dimensions.
Boxes are connected together with the frame using a welding machine or bolts and nuts in case you are going to disassemble your greenhouse for the winter.
As you see having elementary skills of working with a welding machine and grinder, you can build a greenhouse or greenhouse from the profile pipe with your own hands. It will take a lot of time and effort, but all will compensate for good yields grown in comfortable greenhouse conditions.
