How to make a frame for a greenhouse from polypropylene. Drawings and design features. Base for the frame of a greenhouse structure made of polypropylene pipes

One of the inexpensive ones, but effective ways provide yourself with early vegetables, berries, herbs from early spring to late autumn - a greenhouse made of polypropylene pipes, you can build a structure with your own hands in 1-2 days. The product is light, strong, mobile, durable, does not require significant costs and skills in construction, and can be easily dismantled if necessary.

Secrets of building greenhouses from PVC pipes

Greenhouses made from PVC profiles can be built in any shape:

• arched;
• rectangular under a single- or gable roof;
• combined from several sections;
• rectangular buildings with an arched roof.

The design depends on the preferences of the owners and the chosen project. It is important to remember that the more mates, the more connecting elements will be required, which leads to additional costs. It is advisable to arrange structures of small and medium size, 2-2.4 m high, about 3 m wide, 4-12 m long.

Suitable for the construction of greenhouses water pipes pvc, standard diameter 16-110 mm, pipe length is usually 5 m, you can buy the product in cuts: 2,3,4 m. PVC pipes with a reinforced layer of thin aluminum or a mixture of fiberglass and polypropylene are also on sale. They are more durable, but the price is higher; the use of such products for the construction of greenhouses is not economically justified, but the owner is a gentleman.

The optimal polyethylene pipe for a greenhouse has a diameter of 25-32 mm for arched products, 50 or more mm for vertical supports in rectangular structures.

Useful characteristics of PVC pipes

A greenhouse made of polypropylene pipes is durable, does not require additional costs for special care during operation, and is not afraid of an aggressive atmospheric environment, due to the characteristics of the material:

• the service life of PVC pipes is 10 years or more, wear-resistant;
• moisture resistant, do not rot;
• are not afraid of chemical and biological influences;
• do not burn;
• do not emit harmful substances;
• withstand significant mechanical loads and do not deform;
• The material is flexible, which allows you to bend an arc of different radii independently, without additional equipment.

Drawings and design features

For construction, you will need drawings of a greenhouse made of polypropylene pipes; it is not difficult to make a sketch with your own hands: it is enough to think over the shape of the frame, indicating the dimensions and valuable components of the structure. Can be found finished project on the Internet, adapt it to individual conditions. What should be considered if you are drawing a greenhouse yourself:

• what will be the base (foundation);
• construction, materials for gables;
• shape, placement of main components, distance between load-bearing elements;
• docking, fastening of parts.

Plastic pipes can be glued together, mounted on self-tapping screws, soldered with a special device; in the video we offer a practical and simple way on how to connect PVC pipes yourself at home.

The easiest way is to build an arched frame for a greenhouse from polypropylene pipes and cover it with film. Rectangular buildings are more difficult to self-construction, additional calculations will be required, more stiffeners will have to be provided. It should also be taken into account that numerous docking points weaken the structure.

A greenhouse made of polypropylene pipes can be installed with your own hands by one or two people in a few hours. You should choose an open, sunny, flat area.

Preparing the site

It’s better to pour it under the greenhouse strip foundation, or lay out a site around the perimeter of bricks, blocks, rubble stone. The simplest, fastest option for constructing a foundation is a foundation made of a board 50*100-150 mm or timber with ribs 100-150*100-150 mm.

We mark the site according to the drawing, hammer in pegs, and stretch a rope around the perimeter. It is recommended to remove the top fertile soil layer from the pit, 300-500 mm deep. You can dig a trench around the perimeter, 300-400 mm wide, 300-700 mm deep. We level the bottom, fill it with crushed stone - 100-200 mm, sandstone - 100-200 mm, compact it. We cover 1-2 layers of roofing felt. We treat the timber with fireproof, antiseptic impregnations, coat it with liquid bitumen and machine oil. We place the parts in the trench, check the geometry, the diagonals must be equal. We attach it to galvanized corners and long self-tapping screws.

Assembling a greenhouse frame from PVC pipes

We cut the pipes to size according to the drawing with a hacksaw or grinder, and clean the ends with a file.

The first stage is the production of pediments. It is better to assemble them on the ground, and then install them on a prepared foundation.

Scheme for assembling greenhouse doors from PVC pipes

Assembling the doors, you will need: 2 vertical parts, 2-2.1 m high, 3 transverse ones - 700-900 mm wide, connecting elements - 4 corners, 2 tees. The opening is made of 2 vertical posts, 1 diameter, as in the diagram above. The height and width of the opening should be 5-10 mm larger than the door itself. We attach hinges to one of the posts.

Simple scheme on which a greenhouse is assembled from PVC pipes with your own hands

Along the long sidewall, from the outside of the foundation, we drive reinforcement, corrugated rods, 8-12 mm thick, into the ground to a depth of 300-700 mm, depending on the softness of the soil. The length of the rod is calculated individually, taking into account the fact that it should stick out 500-800 mm. The distance between the reinforcement is 600-900 mm, but not more than a meter.

We put a PVC pipe, cut to size, on one end of the rod, bend it, and insert the other end on the opposite side of the foundation. Using this algorithm we install the remaining arches.

Thanks to the elasticity of PVC pipes, the arcs for the greenhouse are the same in shape

To installed greenhouse made of plastic pipes with our own hands was strong, we fasten the arcs to the foundation with galvanized brackets, which can be replaced with wide polymer clamps.

In the same way we install the previously prepared gables of the greenhouse. It remains to connect the frame with transverse elements. We cut the PVC pipes along the length of the greenhouse, and fix them on the frame with plastic clamps, as in the photo below. One transverse element in the center of the greenhouse, at the highest point of the arc; in large buildings, it is advisable to add one more on each side.

Other methods of constructing greenhouses from PVC pipes

A do-it-yourself arched greenhouse made of plastic pipes can be built entirely on connecting elements, but such structures will require large financial costs. Thanks to frequent sections, greenhouses made of PVC pipes with connectors are more durable.

How to attach film to frame

To attach the film to a frame made of PVC pipes, you can cut pieces of 50-100 mm, cut a quarter along the length, you get staples. After the film is stretched over the greenhouse, the resulting latches secure it to the vertical and longitudinal posts.

More ways to attach film to a greenhouse made of PVC pipes:

• mesh throughout the frame;
• ropes;
• on double-sided tape glued to the frame;
• Using strips cut from linoleum, fasten with ordinary self-tapping screws.

How to attach polycarbonate to a greenhouse frame made of PVC pipes

For a polycarbonate covering, it is recommended to make the greenhouse frame from PVC pipes with a diameter of 32 mm. Cellular sheets with a thickness of 4-6 mm are suitable.

The polycarbonate is fastened using self-tapping screws with a 3.2x25 mm press washer. The excess is cut off along an arc with a sharp knife. The second sheet is attached to overlap the first by 100 mm. You can also attach a special detachable docking profile to a frame made of PVC pipes with self-tapping screws, insert sheets into it, and close the joint with a plug.

Look at the reviews of the master who made a greenhouse from PVC pipes with polycarbonate with his own hands; in the video he explains the main stages of installation and mistakes that should be taken into account when constructing the structure.

Lately, in the countryside summer cottages very often you can see such a design as a compact and convenient prefabricated greenhouse made of polypropylene pipes. The enormous popularity of such structures among amateur gardeners is explained primarily by ease of use, reliability and low price. It will cost this lightweight design no more than 2 thousand rubles, but it will last quite a long time. For comparison: the cheapest ready-made prefabricated factory greenhouse costs at least 15,000 rubles from dealers.

How to build a greenhouse from polypropylene pipes: preparation of materials

You can assemble a classic arched PVC greenhouse with your own hands in just a couple of days. The following materials will be needed for its manufacture:

• PVC pipes intended for hot water supply are thick-walled (at least 4.2 mm). It is better to take a thicker option (with an internal diameter of at least 16.6 mm).
• Reinforcing rods are 75 cm long and 10-12 mm in diameter.
• Edged board 150*30 mm.
• Thin slats for attaching the film to the timber.
• Film for greenhouses reinforced or cellular polycarbonate.
• Beam 50*50 mm.
• Nails and screws.

You will also need to buy a couple of pipes of a larger diameter than the pipes prepared for the frame. They will be needed to make plastic latches for the film and door hinges.

A greenhouse is assembled from polypropylene pipes using the following tools:

• Hammer and drill.
• Garden auger or sledgehammer.
• A sharp painting knife.

Choosing a site for a greenhouse

Of course, this structure should be installed on sunny place, fairly well ventilated. You should not install a greenhouse where too much snow accumulates in winter. If the load is too great, the film may not withstand and tear. It is not necessary to comply with this condition only when the structure is planned to be dismantled for the winter. The area for the greenhouse should be as level as possible. The soil on it should be compacted a little.

Base assembly

So, let's start figuring out how to assemble a greenhouse from a polypropylene pipe with your own hands. Before installing its frame, you should carefully mark the selected area. The corners of the wooden frame made from boards must be absolutely straight. You can mark out the soil, for example, using the Egyptian triangle or “two curves” method.

The lower wooden frame is assembled using self-tapping screws or nails. After installation, a reinforcing rod should be inserted into each of its corners from the inside. This will avoid distortions during the frame assembly process.

Once the harness is ready, you can begin installing the important element base - reinforcing fastening rods. The easiest way to make holes for them is with a garden drill, since they must be deep enough (at least half a meter). You can also try hammering the rods with a regular sledgehammer or hammer. However, in this case it is more difficult to achieve absolute verticality.

The rods should protrude about 25 cm above the soil surface. They should be placed on both long sides of the future greenhouse in increments of 50 cm.

Frame assembly

After the base is ready, begin installing the “ribs” of the greenhouse. To do this, the pipes are simply put on the rods on both sides. The result is quite strong arches. At the next stage, polypropylene pipes should be reinforced with transverse stiffeners. They are also made from PVC pipes. The crossbars can be fixed either with wire or with plastic tees. In the latter case, the fittings are put on the arched ribs in advance. They can be soldered to the pipes, but it is better to use self-tapping screws for fastening. In this case, the greenhouse will be collapsible.

The number of transverse stiffeners depends on the size of the structure. However, even for a volumetric greenhouse, more than two or three are rarely used on each side. The only mandatory element of such a PVC design is the upper central transverse plastic “ridge”. Without this element, the film will sag after the first rain.

What does a greenhouse made of polypropylene pipes look like? Drawings and photos of such structures can be seen in the article.

Ends

These elements are assembled from timber, previously carefully treated with antiseptic anti-rot compounds. The film is attached to the timber using self-tapping screws through slats. If desired, the wood can be replaced with the same PVC pipes. In this case, sections of the required length are simply installed on the ends vertically along the edges of the future door. They can also be attached to the first arch with tees. At the bottom, fixation is carried out on reinforcing bars.

To the resulting plastic “jambs” you will need to attach a door assembled from segments. To do this, short sections of PVC pipe of larger diameter are soldered onto one of the vertical posts at the top and bottom. The door is placed on them.

Covering with film

A homemade greenhouse is sheathed from polypropylene pipes, usually with reinforced polyethylene. You should not use regular film for this purpose. Such cladding will not last especially long. It doesn't cost much more, but will last much longer.

It is best to cut the sheathing directly into the greenhouse. In this way, inaccuracies can be avoided. The length of the stripes should be slightly longer than the length of the ribs of the “arches”. The fact is that at the final stage the film is usually tucked under the harness. You can also attach it to the tree through slats. It is fixed to the arched “ribs” with special plastic clips. The latter are made from short sections of larger diameter pipe. These tubes are simply cut, split lengthwise on one side into a narrow strip. The result is a comfortable elastic clamp.

Once the film is securely fastened, the assembly of the PVC greenhouse can be considered complete.

Other designs

Of course, greenhouses made of polypropylene pipes can have not only the classic arched shape. It is very easy to build, for example, a house structure from this material. Its assembly procedure consists of the following steps:

• The board strapping and fastening rods are mounted in exactly the same way as in the first case.
• Next, vertical pipe racks are installed on the reinforcement.
• Then plastic “rafters” are installed from identical sections.
• Connect them with ridge element through tees of the appropriate shape. The “rafters” are connected to the racks with fittings. At the top, each form should be reinforced with a horizontal cross member from a section of turbo.
• At the next stage, transverse stiffeners are mounted (also on tees pre-installed on the vertical posts).

Use of polycarbonate

Greenhouses made of polypropylene pipes are sheathed not only with film. It is quite acceptable to replace it with a material that is also quite flexible and lightweight. It will last longer than film, but will also cost more. It should be attached to the pipes using roofing screws with thermal washers. Unlike reinforced film, polycarbonate can expand and contract when air temperature changes. Therefore, when using rigid fastenings, such cladding will quickly become unusable. The diameter of the holes for ordinary self-tapping screws in sheets should be slightly larger than their rods. In this case, a gap of approximately 1 mm should be left between the fastener head and the sheathing sheet.

Polycarbonate is, of course, a very reliable and durable material. However, more often they are used to sheathe greenhouses on a frame made of a profile or corner. For plastic, budget film is usually still used.

How to care for a PVC greenhouse

As already mentioned, plastic construction It’s better to make it collapsible - with self-tapping screws. In this case, in the fall, after harvesting, it can simply be put away in the garage or outbuilding. If the greenhouse remains in the garden over the winter, snow will have to be periodically swept away from it. Otherwise, the film may not hold up and tear. Polycarbonate can withstand much greater loads. But you still have to remove a layer of snow from it. Otherwise, during the thaw, the casing will be covered with a thin crust of ice. Polycarbonate is absolutely scratch-resistant.

In the spring, the walls of the greenhouse with any type of cladding will need to be thoroughly washed with a soapy solution using a soft cloth.

As you can see, creating a greenhouse from pipes with your own hands is a very simple procedure. Assembly of such a structure takes little time. This light construction costs pennies. So, anyone can easily build a neat PVC greenhouse in their garden.
