Strengthening the greenhouse for the winter with your own hands. The secret of the master shares his experience of strengthening the garden greenhouse for the winter. For strengthening with their own hands, improvised material was used. The result is positive, the greenhouse withstood several snowy winters and did not break. The experience was adopted by the affected neighbors, who, at the same time, purchased greenhouses made of metal and plastic collapsed. Two destroyed greenhouses were covered with polycarbonate, and one with foil. The polycarbonate greenhouse collapsed in the middle of winter, and the polycarbonate covered ones collapsed after several spring snowfalls.

How to make a greenhouse strong for the winter with your own hands

A greenhouse made of galvanized metal profile was donated in 2007 close relative. The greenhouse successfully defended the first winter and went into a very snowy winter 2009-2010 covered with film. Having experience in operating home-made greenhouses on a wooden frame, a reinforcing frame was immediately installed in the new greenhouse. Its installation scheme is simple. First, three poles 6 (1) and 5 (2) meters long are attached. A long pole was attached from below to the top bar of the frame. Fastening is easy. The pole is simply tied with a cord to the bar. Two poles are tied to the upper side bars in the same way. To keep the frame from being pushed into the greenhouse, two thin support pillars are installed between the upper pole and the ground. The installation of poles must be taken seriously. The top of the pole must have a recess for the top pole. The post should fit snugly between the ground and the pole. In the upper part, the pole is fastened with screws to the pole. But besides the collapse of the roof, there remains the danger of folding the walls of the greenhouse. The walls were reinforced with two transverse poles. The poles are tightly screwed with twine to longitudinal poles 5 meters long. In the central part, each pole is screwed with a long self-tapping screw to the support and additionally tightly screwed with twine. These actions turned out to be useful, as evidenced by the photo.

Under the weight of the snow, the greenhouse literally rang with tension. But there was no destruction. During rare visits in winter, snow was shaken off the roof by blows on the film from the inside. Do not hope that the snow will slide from the cover of the greenhouse. It was not snow that was shaken off, but an ice crust that froze to the film. This is the main reason for the destruction of greenhouses - the snow does not slide off, but accumulates, and in the winter of 2010, the snow around the greenhouse lay at a height of 2 and there was nowhere for it to slide! In March, the greenhouse was a huge snowdrift, from the neighboring greenhouses remaining under the film of snowdrifts, only the side racks of the frames stuck out.

In the summer, the support poles are dismantled. The greenhouse can be covered with cellular polycarbonate, but the manufacturer guaranteed the stability of the greenhouse only with a sheet thickness of 10 mm, the cost of this coating exceeds the cost of a possible harvest from the greenhouse for several years, which does not economically justify its installation. The destruction of the neighbor's polycarbonate greenhouse, which had serious damage to the frame after a series of spring snowfalls with frosts and sudden heavy rain during the thaw, also stopped. In the last two years, in order not to worry and not to specially go to clean the greenhouse, the film from the greenhouse is folded at the first snow and remains on the ground until spring. The design of the greenhouse allows one person to install the film in one hour.

Of course, the installation of such a frame is not an invention, but a rationalization proposal for sure. We hope that this recommendation will allow you to save your greenhouse. Do it yourself reinforcing frame for the greenhouse!

Types of greenhouses are now producing a significant amount. There is also a wide variety of manufacturers in our country and, in practice, each production is distinguished by its own specifications execution. The choice is a very responsible matter and a rather lengthy process, as they say, in the first place that comes across, only an irresponsible gardener who does not mind throwing money away can afford to buy.

For housekeeping or dacha economy, gardeners use country greenhouses or hotbeds to provide themselves with early vegetables or herbs. The greenhouse is a low, small-sized structure, with a removable light-penetrating top and when using a greenhouse, the cultivation of garden crops is possible only outside. For a removable top, any covering material is used, it can be lutrasil, ordinary PVC film or reinforced film. The latter can last more than one season.

The greenhouse, as a rule, is a high frame stationary structure that allows the gardener to work inside it.

The greenhouse can be heated or simply a heat-saving structure, of normal strength or reinforced. Covering for the greenhouse can be used the same as for the greenhouse, but preferably made of polycarbonate, so as not to have to buy a new one every season.

Greenhouses can be divided into the following types:

• Gable or house, detached;
• Shed, as a rule, is an extension to the capital structure;
• Arched, based on the frame of which is a vault of a given height;
• Greenhouse according to Mitlider, the main difference of which is a two-level roof with a large transom for ventilation;
• Teardrop-shaped with a lancet arch, resembling a drop of water.

The main supporting element of any greenhouse is the frame, which bears the entire load of not only the cover itself, but also the impact force of the wind and the load of the snow cover.

For the manufacture of the frame, the following materials are used:

• Round or square metal pipe with a section of 20x20 or 25x25mm;
• Metal profile, simply a corner with a section of 25x25 and a metal thickness of 0.5 to 1.2 mm;
• wooden bar.

For reinforced greenhouse right choice must be made in relation to a strong framework. For this, a metal galvanized or powder-coated and made of steel pipe with a section of 25x25 is better suited. If a profile is chosen, then it must be more than 1.2 mm thick, also galvanized or coated with a special coloring powder, preferably with polymer components. Of the coatings for greenhouses, polycarbonate will probably be the most popular. Polycarbonate is made from copolymers, both primary processing and secondary.

It is subdivided into:

• Monolithic, made in the form of sheets with a thickness of 2 to 16 mm, can be translucent or colored;
• Cellular, representing flexible sheets with a length of 6 m to 12 m, the cut shows that it has partitions that divide it into cells that are filled with air.

And the properties of these types of polycarbonate are very different. Monolithic polycarbonate is in no way suitable for covering a greenhouse. Cellular polycarbonate, on the other hand, has great strength, saves heat best of all materials, and is easy to use, because easy to cut, bend, glue, drill, etc. It is he who is used as an external coating for greenhouses. But for these purposes, we choose polycarbonate with a thickness of at least 4 mm from primary processing, and not from recycled materials.

Durable polycarbonate greenhouses: reinforced construction

Climatic conditions in different regions of Russia are very different, and manufacturers are trying to take them into account in the manufacture of greenhouses. Greenhouses with a reinforced frame and a polycarbonate coating with a thickness of 4 mm to 6 mm are produced almost everywhere. Be sure to check when choosing specifications, especially the density of polycarbonate, it should not have a coefficient less than 0.7.

It is advisable to choose a reinforced frame for a solid polycarbonate greenhouse, let it be a galvanized metal pipe with a section of 25x25 mm and a metal thickness of at least 0.8 mm, and if this is a profile, then the metal thickness should be more than 1.2 mm and the section more than 25x25 mm. To strengthen the frame, a step between arches or a crate is used, somewhere around 0.65 m, and elements such as a "farm". Success will be achieved if polycarbonate is attached to the frame with bolts with a rubber gasket, plastic strip tape or special plastic bolts.

When choosing a durable polycarbonate greenhouse, consider:

• frame strength;
• Quality and thickness of polycarbonate;
• Appropriate fastenings of polycarbonate to the frame and connections of the frame itself.

If the technical characteristics are taken into account, then the choice will be made correctly.

Reinforced polycarbonate greenhouses from the manufacturer

In Russia, reinforced polycarbonate greenhouses should practically be used everywhere. To avoid any fakes or replacement of parts, it would be more correct to purchase a greenhouse not from a reseller (dealer), but directly from the manufacturer.

Such greenhouses have a number of advantages, namely:

• Polycarbonate is covered with a protective layer against ultraviolet radiation and transmits light over 80%;
• The frame is made of a galvanized profile pipe with a section of 25x25 mm with all-welded ends;
• Vents and doors are ideally located for ventilation;
• They do not need special strengthening and care in winter.

These greenhouses are lightweight, easy to assemble and there is no overpayment to intermediaries. Additional reinforcement is not required.

How to strengthen a polycarbonate greenhouse for the winter

Depending on which greenhouse is purchased, some actions are taken in winter to strengthen it.

To strengthen a polycarbonate greenhouse in winter, you can perform a number of the following steps:

• Duplicate the frame arcs with a profile, having previously bent it;
• Prepare supports from any durable material, for example, in the form of the letter T;
• Secure the bottom of the greenhouse with additional reinforcing bars.

It is impossible to install props on heaving lands, so that when the temperature drops in winter, the props are not pushed out and the polycarbonate is not damaged. In the fall, it is necessary to check all fasteners, tighten or tighten all loose parts. There are many offers on the greenhouse market, but when choosing, one should not be guided only by cheapness, otherwise, having spent money, you can end up with nothing. Study the offers of local manufacturers, be sure to pay attention to the delivery time, as a rule, handicraft manufacturers have the longest delivery time.

When choosing which greenhouse is the most suitable for you, consider the number of elements in the delivery, if there are too many of them, then it is unlikely that you will be able to assemble such a greenhouse on your own. Also pay attention to the services offered, if it is proposed to contact the installation team yourself, then consider whether this option is suitable. Heavy-duty durable construction is profitable and safe.

The frame of a polycarbonate greenhouse is constantly exposed to significant loads under adverse effects environment. In the absence of additional supports for reinforcement, strong gusts of wind and heavy snow can lead to partial or complete destruction of the structure. A critical factor is the large accumulation of snow on the sloping roof surface. Each gardener should take care of strengthening the greenhouse structure before the start of the winter period.

Strengthening the arched greenhouse from snow before winter:

What can damage the base of a greenhouse in winter?

The arched shape of the greenhouses is convenient, since the snow easily slides off the roof. The reasons for its accumulation are due to the characteristics of cellular polycarbonate:

• In winter, even at temperatures below -15 ºС, inside the building temperature regime reaches +5 ºС;
• The surface heats up, and the snow begins to thaw, and freezes with the sunrise;
• The coating becomes rough and is the basis for a heap of snow mass, which sometimes reaches up to 80 kg.

ATTENTION: The material for the frame is a metal profile. It can withstand a load of no more than 50 kg / m 2, so the structure needs to be strengthened. A safe covering material is glass; a strong frame is built for it, which is not afraid of a large snow cover. If polycarbonate is chosen for the coating so that it does not sag under the snow mass, the thickness of the sheets should be from 6 or more millimeters.

Polycarbonate greenhouses: what determines the strength?

A weak base is the cause of the destruction of the roof. Manufacturers often save on the cross section of a galvanized profile. Products are cheap and affordable, but their quality suffers. You can fix the problem using the following methods:

• Dismantle the structure for the winter period;
• As necessary, dump snow cover from the roof of the greenhouse;
• Installation of special props;
• Acquisition of a model with a reinforced frame;
• Strengthen the frame yourself using a tree or a profile.

Preparing for winter. Reinforced polycarbonate greenhouse:

Before the start of the planned repair of the greenhouse and its strengthening, the building is checked, paying attention to the little things. Polycarbonate is inspected for cracks, dents, swelling, cloudiness. Also, with the help of a level, they check whether there is a roll or distortions. If there is no damage, the walls of the structure are washed out from the inside and outside, disinfected, and if necessary, replace the soil. If there is damage, the greenhouse needs to be strengthened.

How can I strengthen the frame of a polycarbonate greenhouse?

There are several ways to strengthen the structure with maximum reliability and with a minimum financial costs. First, a careful inspection of the frame is carried out: a metal profile for signs of corrosion, a wooden beam for mold. Periodic cleaning and surface coating with special agents will help prevent final destruction. The frame is thoroughly washed. The affected areas are cleaned with a fine “sandpaper”, after the surface they are covered with antiseptics, varnish, anti-corrosion compounds.

Duplicate arcs

Description:

• With the help of a template or a profile bending machine, additional arcs are bent. They should have a smaller radius compared to the supporting structure of the greenhouse. They are made from fittings, rolled metal or durable pipes with a square section;
• They are fixed using electric welding on 5 cm posts of the same material. Arcs of the same diameter are often used, however, they are fixed not from the bottom of the installed ones, but nearby, with an interval of a meter;
• After strengthening the frame, the greenhouse is able to withstand snow weight up to 240 kg / m 2.

IMPORTANT: Using electric welding, the connection areas must be cleaned of scale and coated with anti-corrosion paint.

Replacement of covering material

Before strengthening the frame, it is necessary to examine the thickness of the polycarbonate. For cheap structures, a covering material 4 mm thick is used, but it is not suitable for year-round construction. For reliability, the walls are made of polycarbonate 6 mm thick, the roof (gable roof) - 8 mm.

props

You can strengthen and create a durable polycarbonate greenhouse by installing props. For their manufacture, timber, boards and other durable material are used. There are two types of props. Along the supporting structures, longitudinal ones are fixed to support the roof ridge. Cross supports are attached to the transverse arcs. Despite the need for a large amount of material and the complexity of the structure, the design is reliable and able to withstand a large mass of snow. Often, with the help of an additional vertical element, the roof ridge is strengthened.

Features of strengthening the frame

Strengthening the frame refers to only one type of strengthening. It is necessary to take care of the foundation of the structure. Installing a strip foundation will allow the greenhouse to stand firmly on the ground and withstand strong gusts of wind. However, even in a monolithic and strapping foundation, various reasons can cause cracks to appear. Action must be taken immediately. Often, the base is carefully dug up, in order to avoid an increase in the crack, and the area of ​​\u200b\u200bthe crack is identified. Then it is filled with a special solution.

The installation of supports is carried out before the onset of cold weather, without waiting for the final freezing of the earth.

Possible frame problems

Most gardeners prefer a simple wooden frame. The installation instructions contain minimum requirements. However, in some models, attention is paid to its fastening with L-shaped brackets to the ground. Rebars with a diameter of up to 0.95 cm act as a fastener. The side pressing them is from 15 to 20 cm long. And the long one, which is recessed into the soil, is up to 45 cm.

The above troubles happen gradually. Polycarbonate deteriorates or the building does not lean immediately. Suddenly, a metal profile can bend or a board breaks. It is necessary to react to breakdowns quickly: align the profile, put together the board.

REFERENCE: You can avoid a repetition of the problem by fixing and strengthening the weak spot with an additional column. If possible, replace broken or damaged parts. However, do not repair in frost or rain.

Potential Thermoplastic Problems

If the polycarbonate has darkened or clouded, moisture has appeared in the honeycombs, and the plates are swollen or protrude during hot weather, it is urgent to address the defects. The best option will be a complete replacement of the thermoplastic.

REFERENCE: Small small cracks are “blown out” using special hermetic solutions.

If the owner of the greenhouse structure has discovered a breakdown, he first needs to determine the cause of the trouble, and only then start fixing the problem. Only with such a sequence can you avoid possible troubles in the future.

Finishing the gardening season and completing the preparation of the site for a long winter, special attention should be paid to the greenhouse. Not everyone knows how to prepare a greenhouse for winter correctly. But she must successfully survive the cold, snowfalls and in early spring be ready to receive the first seedlings.

There are several important, key points that gardeners should pay attention to. These are: strengthening the frame, cleaning and disinfecting the greenhouse itself and preparing the soil. Following our recommendations and having carried out all the necessary autumn work in the greenhouse, you can be sure of its safety in the winter, and you can start the first spring plantings without wasting precious time on repairing and arranging the greenhouse.

Strengthening the frame

The main enemy of any greenhouse in winter is heavy snowfalls. Not every design can withstand a heavy snow cap. Therefore, it is recommended to thoroughly strengthen the frame.

How can I do that:

• Place metal or wooden supports around the perimeter of the greenhouse. They are especially needed where a thick layer of snow forms on the roof (usually this happens if the greenhouse is located near the fence or wall of the house on the leeward side). Under the props, you need to put something solid: a brick, a sheet of iron, wooden blocks, etc., so that they do not go into the ground under the weight.
• Usually, additional arcs are included with the greenhouse to strengthen it - these are the ones that need to be installed for the winter, evenly distributed over the entire area.
• And the most effective way is in winter after heavy snowfalls and in early spring, when the snow begins to thaw and becomes heavy, you need to clean the roof of the greenhouse from it.

Cleaning and disinfection of the cover and frame

If you use a greenhouse with a film coating on your site, then the film for the winter must be removed, washed, dried and put away in a warm, dry room until spring. Otherwise, over the winter, the film will become completely unusable and you will have to purchase a new one.

If the film has not torn over the summer, and you plan to use it on next year, then it must be disinfected with a solution of copper sulfate.

Glass-lined or polycarbonate greenhouses also need to be washed and disinfected. For disinfection, you can use a solution of potassium permanganate. Pay special attention to places where a lot of dirt has accumulated (and, therefore, harmful bacteria and pathogens of various unpleasant vegetable diseases): they can be washed with a strong pressure of water from a hose and must also be disinfected.

Broken, cracked glass should be replaced with new ones in the fall (you simply won’t have time for this in the spring). Throw more snow into the greenhouse, it will not allow the soil to freeze deeply and retain moisture.

The frame of the greenhouse also needs to be disinfected: treat the metal structure with boiling water, and the wooden one with a solution of copper sulphate.

It is also necessary to carry out the procedure for fumigating the greenhouse with the help of sulfur checkers or lump sulfur. This procedure kills many fungi, mold, infections, mites, pathogens.

tillage

Once every 5 years, all the soil in the greenhouse must be changed. To do this, remove the top layer of the earth and fill it with a new one. This must be done in the fall.

If the frame is not capital, then you can simply rearrange it to another place.

After harvesting, it is important to remove all debris, tops, and weeds from the greenhouse. Do not put tomato tops in compost, there are too many different pathogens in it. It is better to burn it or take it to a landfill.

Then you can steam the soil. This is done in this way: the soil is covered with a film, under which hot steam is either injected through a hose, or several buckets of boiling water are poured.

Then, the already clean soil must be fertilized with beneficial microorganisms, using the preparations "Fitocide", "Azotofit" and the like for this.

If you do not want to use chemistry, sow mustard in the greenhouse.

With acidic soil, add dolomite flour or lime to it in the fall. Also useful mineral fertilizers: superphosphate or potash fertilizers.

To protect the future crop from scab, rot, late blight, powdery mildew, it is recommended to disinfect the soil with Bordeaux liquid.
