Assembling of greenhouses from polypropylene pipes

Each gardener can assemble a greenhouse of polypropylene pipes by himself.

The greenhouse made of polypropylene pipes can be large and small in size, can have an arched and rectangular shape.

Its frame is lined with strong polyethylene film or polycarbonate sheets, which is able to protect the construction in winter from freezing and subsequent cracking.

And in the early spring will create the necessary microclimate for grown plants.

Products used in the construction of greenhouses pvc environmentally safe for plants and humans.

If you have all the necessary materials, the frame structure is built by yourself for a few days, and can last a fairly long time.

If necessary, the greenhouse on the basis of polypropylene pipes can be easily dismantled and transferred to another territory.

Pay attention to the photos of finished greenhouse constructions, the frame of which is built on the basis of PVC pipes.

Materials for assembling the frame of greenhouses made of polypropylene pipes

During the erection processgreenhouses, a skeleton of thick-walled polypropylene pipes are assembled with their own hands due to the use of specially designed plastic frogs for this purpose.

Connecting parts are recommended to purchase high-strength, made of thermosetting plastic.

For the construction of the frame with their own hands it will be necessary to stock up with the following materials:

• pvc pipes, inner diameter - 16.6 mm, external - 25 mm, wall thickness - 4.2 mm;
• reinforcing bars( diameter 10-12 mm, length 75 cm);
• wooden beams 50x50 mm;
• edging board 150x30 mm;
• steel wire or pvt tee;
• trims for cladding;
• polycarbonate sheets or reinforced film;
• fasteners.

Also add the above list with a tool such as a drill, a hammer, a knife and a garden drill or sledge hammer.

Constructing the base for the frame structure

After the greenhouse has been identified, it will be necessary to mark the plot. Frame frame of the edging board should have strict right angles, as shown in the photo.

You can make markup using the "two curves" method or the technology of the Egyptian triangle.

The lower frame of the frame is mounted using self-tapping screws or nails. To eliminate skewing of the frame, reinforcing rods are installed at its corners.

Then they proceed to the arrangement of the main element - the bearing base of the future greenhouse made of polypropylene pipes, and then fix the fixing reinforcing bars.

With the help of the garden borer, the hands on both long sides of the frame in the ground make grooves at least 0.5 m, with a distance of 50 cm from one another.

After installing the reinforcement, it should protrude from the depressions above the ground level by 25 cm.

AlsoYou can install reinforcing bars by hammering them into the ground using a sledgehammer, but you will need to control the absolute verticality of the elements used.

Technology for assembling an arch framework of polypropylene pipes

When the base for the future greenhouse is completely ready, it is necessary to proceed to the installation of the stiffeners of the building.

For this purpose, the ends of polypropylene pipes are placed on reinforcing bars on both sides. The output is a framework of arches, which is strengthened by mounting transverse pvc pipes.

The transverse elements are connected to the arches with steel wire or special plastic fittings. With the second version of the connection, the arched ribs are equipped with tees in advance.

If the greenhouse is planned to be dismantled after a while, then the tees are fixed to the pipes with self-tapping screws, otherwise soldered.

Based on the size of the object, the required number of transverse edges is calculated.

As a rule, this is 2-3 polypropylene tubes between the arches.

The main load is carried by a cross-section ridge pipe, which is an obligatory part of the structure, without it a film coating hangs down after rain.

Features of assembling the ends of the arched framework of the greenhouse

The end elements of the polypropylene construction require special attention. The ends are assembled from a wooden beam, which must be pre-treated with an antiseptic moisture-resistant substance.

Fixing of film material on the beam is performed with the help of self-tapping screws and rails.

The ends, like the whole frame structure, can also be made by hand from polypropylene pipes.

To do this, measure and cut off pipes of the required length, after which they are installed vertically along the aperture of the future door.

At the bottom of the pvc, the ends are attached to the reinforcement embedded in the ground, at the top fixed to the arch using plastic tees.

To the finished pvc ends, the door leaf is mounted, for this purpose, small pieces of polypropylene pipe are soldered onto one vertical pipe, onto which the leaf is pushed.

We recommend to view the video material on the construction of a hothouse arched structure based on polypropylene pipes.

Assembling a greenhouse with straight walls

If an arched greenhouse is undesirable for some reason, it is possible to build a skeleton made of polypropylene pipes, the shape of which is like a house.

For this, it is necessary to work on the following action plan:

1. Site marking is done. With their hands, the lower strapping of edging boards and reinforcing bars is mounted on the same principle as the construction of the arched greenhouse structure;
2. Then the same vertical segments of polypropylene pipes are placed on the fitting;
3. After the rafters of the future roof are constructed. PVC elements are assembled at the expense of the ridge with the help of plastic tees. The use of horizontal transverse parts on top of the structure will provide the roof with the required rigidity;
4. Also vertical cross stiffeners are equipped with vertical stands of the greenhouse, the top of which was pre-equipped with pvc tees.

To supplement the topic and more fully consider the entire order of actions will allow the following video material.

Greenhouse casing with polyethylene

Often the frame of greenhouses made of polypropylene pipes is covered with reinforced polyethylene film, it is possible to consider in detail how this is done in the proposed video material.

The owners, who for the greenhouse tried to use ordinary polyethylene, could be convinced of the inexpediency of its use.

A simple film quickly deteriorates under the influence of sunlight and temperature changes.

For the production of the desired segments, the sheathing is carried out by cutting the material. Do it better in the greenhouse, which will eliminate inaccuracies and save the expense of the product.

The length of the film strips is longer than the length of the stiffeners of the arches, what the frame has, since the film at the end of the skin is tucked under the lower strapping of the hothouse.

It is also possible to fix reinforced polyethylene by means of laths that are attached to polypropylene pipes of arches due to special plastic clips made by one's own hands.

For their manufacture use short lengths of pipes with a large diameter. Pipes are cut along one side, resulting in an elastic clamp.

After a reliable fixation of the polyethylene sheathing, we can consider the construction of a greenhouse on the basis of polypropylene pipes completed.

Sheathing of hothouses from pvc pipes with polycarbonate

The frame of greenhouses made of polypropylene can be covered not only with strong polyethylene, but also with polycarbonate sheets.

In winter, this material will serve as a good protection for the entire structure, as it relates to the heat-insulating type of construction products.

Its high cost, in comparison with the reinforced film, is compensated by a long service life, high technical characteristics and ease of installation.

A special property of polycarbonate is its ability to expand and contract in the event of air temperature changes.

Therefore, fixing the polycarbonate to the support base should not be carried out using rigid fasteners. Otherwise, the cladding is deformed.

Polycarbonate sheets are mounted on a polypropylene frame structure using self-tapping screws for roof and thermowells.

The holes under the fasteners are drilled with a diameter slightly larger than their rod.

In this case, it is necessary to leave a gap of one millimeter between the polycarbonate sheet and the self-tapping head for the rubber seal.

Despite the best characteristics of polycarbonate, it is nevertheless recommended to mount it on a skeleton base of a metal profile.

Care for the construction of PVC

As mentioned above, the frame of pvc structures can be made in a stationary and collapsible version.

It is best if the structure is assembled on self-tapping screws, it can be dismantled and sent for wintering in the hozblok.

If the greenhouse is left on the street, then in winter it will have to take care of it all the time - to sweep off snow deposits.

Otherwise, the polyethylene sheeting will hang and under the influence of a constant load breaks.

With regard to the stability of polycarbonate to such loads, then this material carries much better film. But nevertheless it will be necessary to look after it.

If the surface of the material is covered with ice crust, then it is not recommended to scrape it, as it is easy to scratch polycarbonate, which is not resistant to such kind of mechanical influences.

Complete the above material with detailed information will allow thematic video material in the article.
