The procedure for assembling a summer cottage greenhouse is 2nd. Country greenhouse: tips and recommendations

Conventional arched greenhouses are distinguished by a shape that is very convenient for snow sliding off. But why does it still accumulate on their roofs?

The point here is the properties of cellular polycarbonate. In winter weather, even if the temperature drops to -15°C, inside the building it is up to +5°. The surface heats up, snow melts on it, which freezes when the sun rises. The roof becomes rough, which forms the basis for the accumulation of a solid snow cover, the weight of which sometimes reaches up to 80 kg.

Now let's compare. The “skeleton” of a greenhouse is usually made of metal profiles, which is the most common material. And the load it can withstand is no more than 50 kg/m2. It is absolutely obvious that the structure needs to be strengthened.

The safest covering material is glass, under which a strong base is usually made in a greenhouse. In the case of such a roof, you don’t have to worry about piles of snow. If you choose polycarbonate, it is best to buy its sheets with a thickness of 6 millimeters or more. They will not bend under the weight of the snow cap.

What does strength depend on?

As has already become clear from the above, the roof can collapse due to a weak foundation. Manufacturers often save on the cross-section of galvanized profiles. At the same time, their products become cheaper and more accessible, but their quality drops noticeably. You can solve this problem in the following ways:

• dismantle the building for the winter;
• periodically remove snow from the roof of the finished structure;
• install special supports (although this does not guarantee the integrity of the building);
• buy a model with a reinforced frame;
• strengthen the base yourself by constructing it from wood or profile.

The planned repair of a structure and its strengthening, of course, begins with an inspection of the structure, including all the little things. First of all, carefully polycarbonate is inspected. Particular attention is paid to all its cracks, dents, and swellings. Cloudiness can also be a cause for concern. In addition, the entire building is checked for tilt or distortion. It is best to use a level for this purpose.

If no damage is observed, the walls of the greenhouse can simply be washed inside and out, disinfected and, if necessary, partially replaced with soil. Well, if damage is still found, the greenhouse will need to be strengthened.

How to strengthen a polycarbonate greenhouse

There are several ways to strengthen the structure as reliably as possible and with a minimum of financial costs.

Even if the frame of a garden structure is made of a metal profile or durable timber, it will never be superfluous to carefully inspect it, identifying all violations. Defects can be corrosive growths on metal components, mold and other “weak” spots on wooden ones.

To prevent the “skeleton” from completely collapsing, it is necessary to periodically clean it and coat the surfaces with compounds specially designed for this purpose. Metal profiles and wood are washed well. It is recommended to clean all affected areas with fine sandpaper, then cover the surface with antiseptics, varnish, and anti-corrosion compounds.

Duplicate arcs

Using a pattern or using a profile bending machine, you need bend additional arcs. They should be of a smaller radius in comparison with the supporting structures of the greenhouse. To make them you will need reinforcement, rolled metal or durable pipes, preferably of square section. Fastening is carried out by electric welding on five-centimeter posts made of a similar material.

Arches of the same diameter are often used. But they are not placed below the installed ones, but next to them, as a rule, a meter apart. This way you can strengthen the frame with maximum efficiency: the structure will withstand a snow mass of up to 240 kg/m2.

Attention! When using electric welding, the joints must be cleaned of scale and coated with anti-corrosion paint.

Replacing covering material

Before strengthening the “skeleton”, it is imperative to pay attention to polycarbonate and its thickness.

Inexpensive kit options are most often made from covering material 4 mm thick. But this is not suitable for such a building to stand all year round. As mentioned above, polycarbonate with a thickness of 6 mm is more suitable for walls, and 8 mm for roofing (if the roof is gabled).

Supports

The most common way to reinforce and create a durable polycarbonate greenhouse is installation of supports. They are made of timber, boards and other durable materials.

There are two types of supports for the polycarbonate model. Longitudinal ones are installed along the load-bearing structures: they support the roof ridge. But transverse supports are attached to the transverse arches, respectively. They require more material, and their structure is more complex. However, the design is more reliable and can withstand heavy snow weight.

Often the roof ridge is also strengthened additional vertical element.

Features of strengthening

We must not forget about the time at which to strengthen the building. Supports are installed until the cold weather until the ground completely froze.

For reference. Heaving soils can become a problem. If in winter the vagaries of the weather lead to thaws beginning to give way to frosts (this is especially typical for the regions of central Russia), the reinforcing structure may be pushed out by swelling soil. And then you certainly cannot avoid its internal damage.

Strengthening the frame is only one type of strengthening. But you should also think about the basis garden building. It must stand firmly on the ground in order to adequately withstand strong winds. This will prevent her from moving without permission.

It should be noted that a lightweight structure, which also has a large windage, can come off the soil surface very easily. Therefore, it would be a good idea to first install it on strip foundation. If all the rules are followed when installing the greenhouse on the base, there will be no problems.

But a monolithic and bonded foundation can crack for various reasons. And here, too, you need to take immediate action. Most often, it is necessary to excavate the base and accurately identify the location of the crack. After this, the fault is filled with a special solution. The digging should be done carefully so that the crack does not accidentally grow larger.

Frame problems

Most often, gardeners prefer a simple wooden frame. The instructions for installing a greenhouse have minimum requirements for it. But in some models attention is paid to fastening it with L-shaped brackets to the ground surface. The fastening element in this case is reinforcement bars (diameter up to 0.95 cm). Their pressing side usually has a length of 15-20 cm. And the long side, recessed into the ground, is up to 45 cm.

All the troubles described above do not occur immediately. Deterioration of polycarbonate or tilting of the entire building occurs gradually.

But a metal profile that suddenly bends or a board breaks can happen suddenly. And you need to react to this as quickly as possible. The metal is straightened, the board is hammered together (as a rule, a block nailed over it with an overlap is enough).

To prevent the problem from recurring, the weak point must be fixed and strengthened by installing an additional column. But if possible replace broken or damaged part completely, you need to do this. It is just not recommended to do this in frost or rain. Nothing good will come of such an undertaking.

Thermoplastic problems

If clouding or darkening of the polycarbonate occurs, moisture appears in the honeycombs, and the slabs swell or bulge in hot weather, these defects should also be eliminated. The surest way is completely replace thermoplastic.

On a note. Small violations such as small cracks are “blown out” with special sealing solutions.

Conclusion

In conclusion, it should be noted that when detecting greenhouse breakdowns and their subsequent elimination, the most important step is identify the cause of the appearance such. Only in this case will similar malfunctions be avoided in the future.

Have you decided to switch from growing in open ground to greenhouse farming? If so, then pay attention to the “Dachnitsa” greenhouse, which fully meets all the requirements for such structures.

Strictly speaking, “Dachnitsa” is not one greenhouse, but a model range consisting of three types of construction. Each of the buildings has its own differences, but in general terms of construction they are the same. “Dachnitsa” - arched greenhouses with a casing made of sheets and a frame made of galvanized metal profile pipe.

All representatives of the “Dachnitsa” model range have the following advantages.

1. Easy to assemble - all structural elements of the greenhouse are pre-cut, processed and welded. All you have to do is bring them to the site, fasten them together with a pipe-to-pipe connection, secure them with bolts or self-tapping screws and lay the sheathing. This does not require any special skills or complex tools, and with proper skill, assembling the Summer Resident greenhouse will take you no more than 4-6 hours.
2. Durability - all frame elements have an anti-corrosion zinc coating. The welded seams are additionally processed and painted, so they will not become a weak point in your greenhouse. The service life of the “Dachnitsa” is limited only by the durability of cellular polycarbonate, which, with proper installation and subsequent care, can last 10 years or more.
3. Reliability – the frame of the “Dachnitsa” greenhouses is designed to withstand increased snow and wind loads. You can find out the exact numbers by referring to the characteristics of each individual model.

Let's consider each model from the "Summer Resident" series separately.

Greenhouse frame Summer resident

- the first greenhouse in this series. It is made of galvanized metal profile with a section of 20x20 mm. Available in several versions, varying in length. The distance between the arches is 1 m. Withstands snow loads of up to 70 kg/m2 and gusts of wind at speeds of up to 15-20 m/s. Produced since 2011.

Developed taking into account operating experience of the “Standard” model. Some changes have been made to significantly increase the strength and durability of the frame while maintaining ease of assembly and low cost. A galvanized profile pipe of 30x20 mm is used for the frame, while the distance between the arches of the greenhouse is reduced from 1 m to 0.65 m. As a result, “Dachnitsa-Usilennaya” can withstand up to 80 kg/m2 of snow load. The reinforced design also increased resistance to powerful gusts of wind.

Important! For reliable wind protection, secure the greenhouse to the ground using reinforcement pins or profile pipes, or, alternatively, to the foundation using anchor bolts or long self-tapping screws.

"Dachnitsa-Lux"

"Dachnitsa-Lux"- one of the most durable models in its class. The arches between the gables are double arches made of galvanized profile 20x20 mm. For reliable fastening, special connectors for profiled pipes are used.

Table. Standard sizes of greenhouses of the “Dachnitsa” model range.

Important! If you are just a beginner summer resident, we advise you to first purchase a small-area greenhouse and gain the necessary experience and skills in growing plants indoors. Subsequently, increasing the area of ​​the “Dachnitsa” greenhouse is very simple - you can purchase an additional 2 m long insert, which is attached to the main greenhouse.

Choosing a location and preparing the foundation

Before you order the “Dachnitsa” greenhouse kit and start assembling, you need to decide where it will be located. Proper selection of a location for a greenhouse significantly affects the yield of agricultural crops.

First, determine the cardinal directions. The greenhouse should be located in such a way that on the south side it is not shaded by a building or trees - the plants in the “Dachnitsa” should receive a sufficient amount of sunlight from morning until evening. From the north, on the contrary, it is advisable to have some kind of “cover” in the form of a residential building, a fence or a hedge - this way the cold wind will not blow across the greenhouse.

Important! The greenhouse cannot be located in the gap between two buildings or at some distance from it - in such places, due to the “wind tunnel” effect, strong and constant drafts are formed, which will depress the plants and worsen the yield.

The greenhouse should be oriented as follows: if there are ventilation windows along its long wall, then they should face south; the wall without transoms should “look” to the north, the gables of the greenhouse should “look” to the east and west, respectively. It is not necessary to orient the building strictly to the cardinal points, but it is desirable to maintain at least approximately such an arrangement.

If your personal plot is located on a hillside, then first build a terrace, slightly larger in area, length and width than that of the greenhouse. Strengthen its slopes with logs, timber, stone or brick so that the soil does not slide down over time.

In most cases, a foundation is not built when installing a “Dachnitsa” greenhouse - it is enough to secure it, drill holes every 1-1.5 m in the base of the greenhouse and drive pins at least 70 cm long into the ground through them. Then the ends are bent in the shape of the letter “L” or connected to the base by welding.

A simple foundation for a greenhouse “Dachnitsa”

And for those who believe that even such a light greenhouse needs a foundation, instructions are provided for arranging a simple, inexpensive and fairly reliable structure made of timber.

Step 1. Take measurements and mark the area. Use a tape measure, pegs and ropes stretched between them. Thus, you should be able to mark the future trench for the foundation.

Step 2. Dig a trench around the perimeter of the future greenhouse. The width and depth must be equal to the cross-section of the beam (usually 150x150 or 100x100 mm).

Step 3. Compact the bottom of the trench and fill it with a 10 cm thick layer of sand or gravel.

Step 4. Cut the timber - two sections along the length of the greenhouse, two along the width.

Step 5. Make cuts for a half-tree connection.

Step 6. Treat all sections of timber with an antiseptic.

Important! Some instructions for arranging a timber foundation require laying a layer of roofing material or other waterproofing material on the bottom and walls of the trench. It is undesirable to do this, since during heavy rains the roofing material will create a kind of “bathtub” for the timber, in which it will constantly come into contact with the liquid and be destroyed. Place any waterproofing on top, directly on the timber.

Step 7 Lay the timber in the trench, connect it together, without fasteners yet.

Step 8 Use a level to check how evenly the wood is laid.

Step 9 Use a tape measure to measure the diagonals. If they are equal (or have minor differences), everything is done correctly.

Step 10 Connect the beams together using dowels or long screws.

Important! If desired, you can dig “supports” made of brick or concrete blocks under the beam.

Assembling the greenhouse “Dachnitsa-Strengthened”

Now that you have your area cleared and ready to build your greenhouse, check that all framing members and fasteners are in place. To do this, use either the list of parts included with the Summer Resident greenhouse kit, or the table below.

List of components for the greenhouse “Dachnitsa-Strengthened” 6x3 m

Important! Side windows, partitions, spacers, stakes and inserts are not supplied in the basic kit and must be purchased separately.

For convenience, all structural elements of the frame are indicated by numbers from the table above. Fastening is carried out using bolts and nuts with washers; all holes for them are made in advance. For secure fixation, use a wrench or a special screwdriver attachment. The assembly process begins with the pediment of the “Dachnitsa-Usilennaya” greenhouse and the adjacent arches.

Step 1. Attach four horizontal posts 4 to door 1. Secure with bolts.

Step 2. Attach the upper part of the arch 3 to the door from above.

Step 3. Attach the vertical supports of the arches 2, left and right, to the ends of the upper part of the arch 3 and the horizontal posts 4.

Step 4. Attach the lower and middle longitudinal elements 5 and 6 to the resulting pediment structure, on the left and right sides.

Step 5. Between the longitudinal elements 5 and 6, secure the vertical posts of the intermediate arches 2.

Step 6. Attach the upper longitudinal element 7 to the top of the pediment.

Step 7 Between the longitudinal elements 6 and 7, connect the upper elements of the arches 3 on both sides of the greenhouse.

Step 8 Strengthen the connections, check the correct assembly and reliability of the fasteners.

Repeat all these steps with the opposite gable. Now you need to assemble the intermediate part of the greenhouse frame and connect everything to each other.

Step 1. Attach vertical posts 2 to the lower longitudinal elements 5.

Step 2. Attach the middle longitudinal elements 6 to the resulting structure.

Scheme of fastening longitudinal elements (6)

Step 3. Connect everything using the upper parts of the arches 3 and screw the upper longitudinal profile 7 onto the screws with a countersunk nut.

Step 4. Assemble all the intermediate frame parts together. Check the reliability of fasteners and completeness.

Step 5. Connect the two gables and the intermediate part of the “Dachnitsa” greenhouse together. At this stage, pay great attention to the reliability of the fasteners.

The final part of constructing the frame for the Summer Resident greenhouse is leveling and fixing it to the ground.

Step 1. In places where pins are installed or secured to a timber foundation, drill holes of the appropriate diameter in the base of the frame.

Step 2. Install the greenhouse in the designated area. Use a level to check how level it is.

Step 3. If a slope is detected in one direction, compensate for it using supports and soil.

Step 4. Insert the pins into the holes drilled in step 1 and drive them into the ground. If it is attached to a beam, insert long screws and tighten.

Step 5. Bend the ends of the pins protruding from the ground into the shape of the letter “L” and turn them so that they (the ends) do not interfere with your future use of the greenhouse.

After this, you can start installing door handles, hooks and wraps. If, in addition to the basic set of the “Dachnitsa” greenhouse, you purchased vents or spacers, then install them as well. Check how strong all connections are, repeat several opening and closing cycles for each door, window and transom.

Covering the greenhouse "Dachnitsa"

Now all that remains is to mount sheets of cellular polycarbonate on the frame of the “Dachnitsa-Usilennaya” greenhouse. Use a screwdriver as a tool, and for fastening, use roofing screws and rubber gaskets. Start lining the greenhouse from its gables.

Step 1. Cut one of the polycarbonate sheets into two equal parts.

Step 2. Remove the protective film from them.

Step 3. Place half of the sheet against the gable, with the side with the stabilizing coating facing out.

Step 4. Screw in self-tapping screws with thermal washers throughout the arch.

"Dachnaya - 2D". Size 3x2x5.4m.
The area of ​​the covered soil is 16.3 m2.

Large greenhouses for film “Dachnaya” and “Dachnaya-2D”: 3 m wide, 2 m high and 6.2 and 5.4 meters long.
The “Dachnaya” greenhouse has one doorway and vents at opposite ends. The back wall has the shape of a cone. The “Dachnaya 2D” greenhouse has doors and vents at both ends. The film fastening is also very well thought out. The film is attached with special clamps from below along the entire length of the greenhouse, on the door and window. And also with arc clamps at both ends. To fully tension the film, the kit includes threads with hooks. The increased coverage area allows you not to limit yourself to one or two crops, planting various types of vegetables, berries and herbs.

"Dachnaya - 2DU"
Size 3x2x6m.
Covered soil area – 18 m2

A reinforced version of the “Dachnaya-2DU” greenhouse under film for open summer cottages or regions with strong winds.

Be careful when choosing a greenhouse! Under no circumstances should film greenhouses be covered with polycarbonate, because... If there is heavy snowfall, the frame will deform and the greenhouse will collapse.

Greenhouses under cellular polycarbonate

"Dachnaya-2DUM"
Size:
Width – 3m;
Height – 2m;
Length – variable from 4 meters, increasing by inserts of 2 meters.
Covered soil area – from 12 m2

The greenhouse “Dachnaya 2DUM” has doors and vents at both ends, has special reinforcements for the frame arc, and the spans do not exceed 50 cm, which is necessary for cellular polycarbonate with a thickness of 4 mm. It is important that solid 6-meter polycarbonate sheets are used to cover the top. In this way, the greatest thermal insulation is achieved. To maintain heat in a greenhouse, it is initially important correct installation not only the frame, but also cellular polycarbonate. Cells and joints of polycarbonate must be sealed with tape or filled with transparent sealant. Complete insulation of gaps around doors and vents is not necessary when using a greenhouse in the spring and summer. But if you want to use the greenhouse all year round, it is of course better to avoid gaps as much as possible, and also, you need to buy a thicker one cellular polycarbonate, 6-8 mm depending on the region.
Measurements in the Dachnaya-2DUM greenhouse covered cellular polycarbonate, showed: on a sunny January day, when it was minus 30 degrees outside, the surface of the soil inside the greenhouse was 0 degrees. At night, when the sun is not heating, the temperature inside, of course, gradually drops, but a 1 kW heater, with this frost outside, increases the internal temperature by 10 degrees.
The design can easily withstand snow loads, icing, hail, and sudden temperature changes. The polycarbonate coating does not burn, but melts when exposed to prolonged temperatures. This should be taken into account and the greenhouse should not be fouled.

Greenhouse frames are compact and fit into the trunk of a car. Cellular polycarbonate is rolled (all sheets) into one roll with a diameter of 1.2 m and a length of 2.10 m. To transport a greenhouse with polycarbonate, you need a car with a roof rack (for short distances), a trailer or a gazelle (for long distances).
You can also use our delivery services.

The greenhouse frame is supplied in four packages with a total weight:

• 4 m long - no more than 65 kg;
• 6 m long - no more than 80 kg;
• 8 m long - no more than 100 kg.

The weight of one polycarbonate sheet is about 10 kg.
1st package - straight parts and instructions: (1250x100x50 mm.).

The frame is assembled using threaded connections without welding. The largest dimension of the frame parts is 3 meters.

Comparative characteristics and prices

The greenhouse under the film Dachnaya-2DU is designed for installation in open areas with strong winds. The design of the greenhouse has two doorways at opposite ends; each doorway has a door with a window for ventilation.

The “Dachnaya-2DU” greenhouse has a larger number of arcs and transverse parts compared to the “Dachnaya-2D” greenhouse for film: 9 longitudinal elements instead of 5, 11 arcs instead of 7.

Greenhouse frame “Dachnaya-2DU” made of galvanized metal profile 0.8 mm thick. Profile shape - Distance between arcs 60cm. The frame is assembled using nuts and screws.

The greenhouse package includes: frame parts, clamps for the covering, the entire necessary set of fasteners, door hinges, screws for assembly and detailed instructions for assembling the greenhouse with illustrations.

A foundation is not required to install the greenhouse; the greenhouse is installed in the ground by burying the T-shaped ends of the arcs. To fasten the upper part of the film, a thread stretched along an arc is used, secured in the holes of the arc with hooks. Along the extreme arcs and at the ends of the greenhouse, the film is secured using clamping strips. To increase the durability of the film, it is recommended to make gaskets between the frame and the film from pieces of old film or from non-woven material; this prevents wear of the film from friction against the frame in the wind.

The film covering is not included in the main kit; at the buyer’s request, the greenhouse is equipped with a special greenhouse film 150 microns thick, six meters wide.

Dimensions of the greenhouse "Dachnaya-2DU" assembled:
