Dugi for a greenhouse with their own hands: materials, instructions
In modern markets, fruits and vegetables are offered for sale in a wide range. Despite this, amateur gardeners are not getting smaller. Some of them acquire ready-made greenhouses, while others produce them independently. If you belong to the latter, you probably wondered more than once how to make arcs for a greenhouse.
Variety of options
The basis of such structures usually lie handy materials, namely: plastic bottles, pegs, window frames. Sometimes greenhouses are made of PVC pipes, which are covered with a film. You can do this work yourself, and you don’t have to spend much money. However, you can make arcs from a variety of materials.
Making arcs from plastic is the easiest way
If you want to save time, it is best to choose plastic water pipes, which are inexpensive, and allow you to experiment as much as you like.Along the perimeter of the future greenhouse it is necessary to drive pins that will look out of the ground by 15 cm. Curved strong pipes are put on the pegs. You must calculate their number. Everything will depend on the height of the structure. It is important to consider the distance between the supports, which should not be less than 50 cm. In this case, the film will not sag.
Arches for a greenhouse made of plastic can be very different. However, when working, it is important to consider that the structure must resist the wind well. From above across it will be necessary to lay one more pipe that will link the arcs between them and keep the greenhouse from tilting. The painting grid for plaster will be an excellent assistant in this matter. It must be made of fiberglass. The material is laid over the film and pressed along the edges.
Additional recommendations for the manufacture of PVC arcs
The distance between the arcs should not be more than one meter. In order to bend a pipe made of polyvinyl chloride, you should use a building dryer. It is set to a temperature of 180 ˚C. Fiberglass reinforcement can be used as arcs.It has two main advantages, expressed in lightness and flexibility.
On the wooden frame it is necessary to make holes, the diameter of which will correspond to the diameter of the reinforcement. Between the arcs must be maintained interval of 50 cm. Next, the arc is inserted into the opposite hole. When choosing this material you can be sure that the design will be strong and durable.
Using Combined Arcs
Greenhouse arcs can be made of metal. This option will be more durable and durable, but the work will be somewhat more difficult. Additionally, you should prepare all the same plastic pipes that may even be defective. Metal rods should be such that they can wear plastic tubes. For work fit construction fittings.
The rods should be cut in such a way that to get workpieces of 60 cm. 20 cm of the rod should be hammered into the ground, 40 cm should look over the soil surface. Once the rods are clogged, water pipes can be put on them. Their length is determined in advance. At this stage you can take help.One person will have to hold the elastic wire at the edges of the greenhouse to the ground. The central part of the wire rises at the same time, which will allow you to determine the desired length. The resulting pattern you can attach to the pipes to make them easier to cut.
The strongest material among the others listed is metal. It can form the basis of arcs. Experienced to determine their length. Then you need to take the pipe, the length of which is 2 times more than half an arc. This element is cut into two identical parts. To the horizontal pipe, which will be strengthened from above, it is necessary to weld the tees, and along the length - the crosses. The distance between them will be 0.5 m. The cut parts are welded to the pipe through the crosspiece. At the extreme arc where the door will be installed, you need to solder two tees so that they are facing the third hole down.
Now the elements can be welded to the walls of the greenhouse, but the last ones should not be used yet. The design is aligned with the length and fixed by a transverse tube, where there are two tees for the door racks. Now it remains only to cover the top with a transparent film.
Why choose metal arcs
Greenhouse arches for garden beds can be made of metal. This material has many advantages. First, it is durable. If you protect it from corrosion, then he will be ready to serve for much longer. The metal can be painted with an anti-corrosion compound, or you can purchase finished products protected by galvanization. If you apply reinforcement, then from time to time it can be tinted, because the paint will peel off.
The construction of metal is best done arched, because in this case, it turns out pretty strong. If something falls on top, the roof is unlikely to fail or collapse, but this condition is observed only under the condition that the arcs are well fixed in the soil.
Having installed metal arches for a greenhouse, from time to time you will have to change the cover, then the construction will be ready to serve for several decades. The metal frame is also good because it can be covered with almost any material. Having made metal arches for a greenhouse with your own hands, you should be prepared for the fact that they are durable, but heavy enough. If you install a greenhouse with such a frame, it is important to ensure that the elements are well secured.Otherwise, strong wind gusts can drop a greenhouse, and heavy metal will be damaged. The design can be restored, but the green spaces will be destroyed.
When choosing material for greenhouse arcs, you must bear in mind that the metal is quite difficult to bend. This is one of its main drawbacks. In this regard, metal frames are often purchased in finished form, and not made independently. Otherwise you must have the skills of a welder. The technology thus provides a connection to the arcs of a metal crossbar, which will be on top and is called ridge. Sometimes the connection is made from the bottom, you need to use a pair of metal long parts. In this case, the construction is almost indestructible.
Having considered a photo of arches for a greenhouse, you can stop the choice on metal products. However, they have another disadvantage of high cost. Plastic is cheaper.
Use old hose
Greenhouse arcs can be made from a watering hose. So you give him a second life.The hose is cut into equal parts, and willow rods are inserted into each of the pieces, which must first be ground at one end. The blunt end should be facing inward.
The hose is fixed to the ends of the rods and bent. Now the elements are inserted into the ground around the perimeter where the table will be installed. Then it remains only to stretch the film. The arcs for a small stable structure can be made of 10 mm wire. It can be purchased in the rings, and then cut the grinder.
Use of scrap materials - wood, old hoops, backs from beds and old cots
An excellent material for the manufacture of the frame, and hence the arc, can be wood. The problem can only be expressed in that the scope of work will be quite large. Frame details will be light and stable. The main disadvantage of wood is the fact that it quickly rots in the lower part, where it contacts with the soil. You can eliminate the problem by processing the material with a special tool.
Plastic arches for a greenhouse can also be made from old hoops. They are cut in half, and then using pegs stuck into the ground.From above system can be fastened with a wooden bar. This method of manufacturing greenhouses was popular in the USSR. The pipe for greenhouse arcs can be made of old folding beds and spring beds with steel backs. The latter form the basis of supports, as are the clamshell legs. However, the design will be U-shaped. On such a roof precipitation may accumulate.
How to choose a covering material for each of the presented options of arcs
The most simple, but short-lived variant of covering material is plastic film. It may have a certain density, which indicates the life of up to two seasons. The material transmits about 80% of the light, which is enough to prevent the plants from stretching.
An alternative solution is polyethylene reinforced film, which is ready to serve a little longer - three or four seasons. This option is simple and durable. You can choose cellular polycarbonate. It is modern and of high quality, and allows plants to ensure healthy growth. Using cellular polycarbonate, you will need to use aluminum fasteners.This material has a high service life, which reaches 10 years. Some craftsmen acquire and air bubble film, which perfectly manifests itself in cold latitudes.
The store today presents light-converting polyethylene film, which provides the optimal temperature without overcooling and overheating. Light waves, which are necessary for metabolism and photosynthesis, penetrate through such a film. Such material shortens the growing season, and ready to serve for about four seasons and more.
To buy a ready-made greenhouse today is much more expensive than making it yourself. In the latter case, you can even apply materials at hand, which is especially true for arcs. Today they are made of plastic pipes, garden hoses, wood, and even plastic hoops.
