Want to have on your table natural fresh and fragrant vegetables, the amount of pesticides and herbicides that would not exceed the norm, and even all year round? Then you just need to build a greenhouse on the dacha. Do not have a large amount to buy it? Not scary. In this article we will look at how to make a greenhouse out of glass with your own hands, give drawings, photos and video instructions.
The advantages of glass greenhouses
Below are just a few Advantages of glass greenhouses:
Of course, a greenhouse made of glass also has negative sides that must be considered when constructing it. For example, the fact that glass is a rather heavy material (1 m² of glass with a thickness of 4 mm weighs 10 kg, and 6 mm - 15 kg) should affect the presence of a solid foundation, as well as the construction of a sturdy construction - a frame. But unlike greenhouses covered with other materials, experienced amateur gardeners close their eyes to the shortcomings of glass-covered greenhouses, because, in their opinion, not only do green plants grow glass and bear fruit, but also get sick less.
Properly select the location of the building
There are small tricks regarding the choice of location under the greenhouse. The following factors are taken into account:
Project selection and drawing up drawings
To to facilitate the construction process, it is necessary to choose a project, that is, a plan for the construction of a glass greenhouse developed before us, and to correct the drawings.
What should be foreseen at this stage? Much will depend on the architectural shape of the greenhouse. Since you will cover it with glass, and this material does not bend, the choice is narrowed. It is better to stay on a rectangular or multifaceted greenhouse under a single or gable roof. However, if you wish, the roof can be given a pyramid shape with four or more edges.
If you have a greenhouse of round shape sunk into the soul, then you need to take into account the bad the air exchange characteristic of this type of building can be improved by installing several additional side vents in the roof.
The wall shape of the greenhouse will help you save space on the summer cottage. In addition, you put less effort on its heating.
It should be mentioned that combined greenhouses under glass are the most popular. In this design for the frame take a bar 50 * 50 mm, and often glazed with old window frames, which will save you money. Someone puts the windows in the PVC profile. At the same time, the upper tips are qualitatively strengthened and an arched roof with metal trusses is installed.Cover the roof with polycarbonate or plexiglass.
Having decided on the shape of the future structure, you need to go to the drawings. Someone who will do the classic way - using a pencil and paper, and someone who has a basic basic knowledge of the PC, can make them in 3D, for example, using the program Google Sketch Up.
Greenhouse glass scheme
The drawings are a very important step in building a greenhouse, as they will help you calculate the necessary the amount of consumables and determine how much money you need to make it.
For example, let's take the draft of a gable glazed greenhouse made of wood and see what needs to be reflected when drawing up a drawing. If you take the standard format of glass 1600 * 2200 mm, 4 mm thick, and a bar of 100 * 100 mm, then we get the ideal distance between the vertical posts, which will be equal to 800 mm. It is noteworthy that it will be half the width of the sheet.
Since the building will be used in winter, the base should be raised above the ground (if 1/2 of the glass height is 1100 mm, then the base should be raised by 900-1200 mm).
The maximum slope of the roof covered with glass will be 15 o . Roof rafter system is preferable to build from a bar 50 * 50 mm.
So, you have chosen a suitable place for the construction of the greenhouse and calculated its dimensions with the help of drawings. Now with the help of pegs and rope, you can make the layout of the site under construction.
Trench for the foundation
Go to the crucial moment - laying the foundation of the greenhouse. It should be noted that with properly flooded foundation, you can save up to 10% of heat in winter.
Experts recommend the use of strip footing, which provides the strength of the structure. In this case, the concrete is poured to the depth of soil freezing (from 55 to 80 cm).
How to fill the foundation for a greenhouse from glass?
Erect a plinth 10 cm high above the foundation, while building up the formwork. Using a level, level the top of the formwork and refill the concrete layer to the edges. To create a waterproofing, lay a narrow strip of roofing material or bitumen mastic on frozen concrete. Now, to a height of 1/2 brick at the base of the strapping, make a brickwork. You can slightly change the process of pouring the foundation, however, the principle remains the same - the use of mortgage reinforcement and waterproofing material.
The foundation should be additionally insulated from all sides with polystyrene foam plates.
Now it's time to make the frame. Recall that greenhouses made of glass especially need a strong and durable frame, which can be built from both metal and wood. The first is characterized by its durability, the second - environmental friendliness.
For the erection of a metal frame, pipes or angles of steel are used, and for a wooden frame, bars of 100 mm are used, which are ideally made of autoclaved wood and guarantee the long service life of the structure.
If the wood does not have the proper impregnation, then it should first be prepared by treating it with an antiseptic, then with a stain, and finally paint it. Most of them use old window frames for glazing greenhouses, and the framework for such a building is made of 100 * 100 mm bars.
The manufacturing process for a greenhouse is as follows:
Now you need to make a roof truss system. For central risers, screeds, as well as intermediate racks, a timber of 10 * 5 cm is used. The roof lathing and door frame can be made using 10 * 3 cm bars. Note that the frame with strut fastening is fastened with a cutting point and subsequent twisting with screws.
Farms gather on the land. Then they are raised on the frame and to avoid deformation of the roof, fixed on the slide. Finally connect the trusses with a ridge bar.
Now you can glaze the finished structure. The glasses are fastened with the help of carnations and silicone sealant, and outside they are upholstered with a rubber or wood bead. The roof is covered with glass from the bottom up, laying it on a layer of putty.
In such a simple way, you can independently build a greenhouse from glass. If you wish to supplement the information in the article with valuable tips, write your comments.
