We build a greenhouse from a galvanized profile pipe

Types of greenhouses and greenhouses

First of all, it is worth learning that a greenhouse and a greenhouse are, in fact, different designs. A greenhouse is a much simplified option. Usually this is a structure of low height, and you can work in it only by removing the film or polycarbonate that covers the greenhouse. In addition, in this case, soil heating is carried out due to the decomposition of biofuel introduced under the garden bed, as well as sunlight.

The greenhouse always has such a height that an adult can calmly straighten up in it to its full height. This means a larger volume of internal space, which is not so easy to warm up, and therefore even in personal greenhouses built with your own hands (not to mention industrial ones), there is gas, electric or wood heating. Greenhouses can also be classified according to their shape: semicircular (arched), with a gable roof (houses), with a polygonal roof. The choice of form depends on various factors - the material used for the construction, the seasonality of use, the intensity of precipitation and wind in a given area.

Finally, there is a classification according to the type of materials used for construction. The frame can be assembled from wood, metal reinforcement, metal-plastic, galvanized profile. A greenhouse, as a lighter structure, can be assembled on a plastic pipe frame. For shelter, a dense film, polycarbonate, and, extremely rarely, glass are used. Specialized stores and websites offer a wide selection of greenhouse designs, but you can also always assemble it yourself.

Advantages of galvanized profile pipes

We recommend paying attention to galvanized greenhouses, which are easy to assemble with your own hands. The frame of such greenhouses is assembled from a galvanized profile (square or rectangular in cross section) pipe. This approach has several advantages. The galvanized profile is practically non-corrosive, which automatically means a long service life of the greenhouse. Such a pipe can withstand serious weight loads, which means that it will be possible to lay a heavy film on the frame of the greenhouse, but a denser polycarbonate. At the same time, the profile pipe has a small dead weight, which means that the frame from it can be easily and quickly assembled or disassembled with your own hands, transported from place to place, and stored for the winter.

Drawing and calculation of the amount of materials

For example, let's take an ordinary greenhouse-house, measuring 3 by 6 meters. You will need a 40 * 20 profile for horizontal and vertical corner parts of the frame and 20 * 20 for vertical ones. The total number of the profile is 40 * 20—18 (lower perimeter) + 18 (upper perimeter) + 6 (ridge beam) + 6 (with a wall height of 1.5 meters) meters - a total of 48 meters of a shaped pipe. The vertical posts must be fixed at least every meter, that is, 16 cuts of one and a half meters - on the wall frame.For the roof frame, another 14 cuts of two meters will be required, for a total of 52 meters of a 20 * 20 profile. This is the minimum, if desired, the frame can be strengthened with additional diagonal ties and horizontal guides - the amount of material must be calculated additionally.

To fasten the profile, you will need crabs of the corresponding section: 8 angular, 52 T-shaped. Where the pipes are not connected at right angles, bolts will be needed. Other necessary materials: sand, cement and reinforcement for the foundation, polycarbonate for cladding. You can also use plastic wrap with a thickness of at least 1 mm.

Mounting

The construction of the greenhouse is carried out on a flat ground, in a well-lit area, orienting the structure from north to south along its length - this will maximize the use of daylight hours. The first step in building a greenhouse with your own hands is marking the foundation. Along the perimeter of the future greenhouse, you need to dig a narrow trench 20-30 centimeters deep. This volume is filled with concrete. Before pouring concrete, reinforcement is driven into the ground.
After the concrete has frozen, it is necessary to weld to the reinforcement a profile for the base under the frame - a rectangle of 3 by 6 meters. Vertical racks are mounted to it with the help of corner and T-shaped crabs.

The roof frame is assembled partly with crabs and partly with bolts. If a year-round greenhouse is planned, it is better to weld all the joints of the profile pipe. The next important step is polycarbonate sheathing. You can attach polycarbonate sheets to profiles with your own hands using self-tapping screws for metal. Experts recommend using thermal washers as a cushioning element in this case - due to the different degrees of thermal expansion of the self-tapping screw and polycarbonate.

Although the more common and cheaper way is with regular rubber washers. The film can be attached to such a frame using a cord. But, given its fragility, it is more logical to choose polycarbonate. The film will have to be removed for the winter, or even changed every season.

Pediment, door and window

For sheathing the pediment in a greenhouse-house, you will need to cut polycarbonate with a triangle. At home, with your own hands, this can be done with an ordinary knife or jigsaw. It is advisable to mount the greenhouse door in the end wall and the size of the door should be at least 90 by 180 centimeters. It is advisable to fasten the door to the frame using outrigger hinges.For ventilation, you need to provide a window in the roof, through which the hottest air will come out of the greenhouse in hot summer. For fresh air inflow, you can open the door or provide an additional window in the wall during installation.
