Beautiful and practical canopies and visors from cellular polycarbonate: characteristics of the material, the method of roofing roofing, production and installation of the carrier frame
On the country site, with time, the need for additional economic buildings often occurs. Moreover, in many cases, it is quite possible to do without a wall-one roof. Vnashy days beautiful and practical canopies make a cellular polycarbonate.
No bad weather ...
Polycarbonate is a type of organic glass, in many respects (including light-consisting ability and strength) superior other popular transparent plastic polymethyl methacrylate. The most common cellular polycarbonate panels consisting of thin layers bonded with each other remote jumpers, or ribbing ribs (such a solution saves an expensive polymer and makes material several times cheaper). Cellular polycarbonate today is available to everyone and everywhere, its rolls (gears with 2.1 m and lengths up to 12m) can be found in almost all building supermarkets and in many business markets. These are products "Safaplast" (Russia), Lexan (Austria), Marlon (United Kingdom), Plastilux (China), Polygal (Israel) IDR.
A little about sailing sports
Scope roofing from polycarbonate on a relatively light frame capable "work" as the most real sail. Entered the weather pressure on it is very large, and two threats arise. Due to the aircraft strength, the wind can disrupt coverage from the crate. That this does not happen, it is necessary to have a fastener, clearly following the tips of the manufacturer (with a step of 350-500mm), and cannot be reduced the diameter of the retaining washers. Much worse if the whole belonging to the ground. How to avoid a similar catastrophe? For this, the frame racks are not just injected into the ground, and be surely concreted either fasten with anchors to the concrete castings in advance. The depth of the embezzlement of such a foundation should be at least 700mm with a diameter of 150mm columns.
Vmassa polycarbonate is painted in tens of tones. In addition to the transparent, the most common blue, bronze and having various shades of brown. Transparent polycarbonate passes up to 80% of light, in colored sheets this indicator is about 2 times lower.

1.2. The roofs with open metal frame, made according to the "spider" schemes (1) or consisting of arched farms (2), look easily and elegantly and can decorate the facade. 3. A canopy for entry alley will protect the garage gate and road surface from precipitation. The deadline for execution of the order to a similar structure is about 1mes. 4. Constructive solutions of automotive canopies are quite varied. Flat, duplex and multi-leveling roofs are possible (it should be borne in mind that the snow comes from the roofs of a complex shape). However, the most common rounded (arched) rods. They are best confrontation with snow loads, but in design errors may have a very large sailboat
A very valuable property of polycarbonate is the ability to filter the short-wave UV radiation, harmful not only for a person, but also for a wide range of enamels and paints. The trouble is only that the material itself, despite the presence of a film that protects against ultra-screw rays is subject to degradation under the influence of ultraviolet and high temperatures. After 10-12 years of operation, microcracks arise in its structure, the strength decreases, bright colors dump, and white acquire a yellowish tint.
For canopies, sheets of 8-10mm thick are suitable (thicker multilayer panels do not make sense - they are used in "warm" structures). The cost of cellular polycarbonate depends mainly on the thickness (350 rub. For 1m2 with a thickness of 8 mm, from 390 rubles. - 10 mm) and coloring (the difference in price between 1m2 transparent and color material is 15-5 rubles.).
The coefficient of linear thermal expansion / polycarbonate compression is noticeably lower than many other plastics (thousandth percent shares with an increase in temperature by 1 s). WHAT The same when installing holes for fasteners are made by 3-5mm more than the diameter of applied screws or bolts. To ensure the waterproof of the design, use special plastic washers with a seal and a cover for a screw screw (like many modern roofing nails and self-tapping screws).
The visor from the transparent polycarbonate will perfectly fit into almost any architectural composition of Policarbonate so that the internal ribs of stiffness are perpendicular to the eaves. Those who chose the arched or vaulted roof should take into account that the bending radius of the 8mm thick sheets cannot be less than 1400 mm, and with a thickness of 10mm- 1750mm. In order to inside the cells, dust fell and insects were filled, ends of the panels necessarily be seized with a special ribbon or put on them P-shaped profiles-plugs. Experts recommend hermetically close the ends, located in the skate of the pitched roof, and for eaves to apply a tape with microporphoration, this is necessary for the flow of condensate. Racing roofs with a perforated ribbon are covered by both ends. Sheets are joined by profiles from the same material. There is a special profile and for the device adjoining to capital walls. Places of "landing" of the docking profiles are pre-sealant (polybutylene mastic is suitable for polycarbonate, and the usual sour silicone is not suitable).

5. Polycarbonate is painted in different colors. The most common shades of blue, green and brown, as well as transparent sheets. 6-8. Mounting kit: 6-end plugs; 7- self-controlling screw; 8-skewers
If the listed rules are followed, this unusual roofing material is faithful and the truth will last at least 10 years. However, we will not forget that the basis of the construction (and the most expensive part of it) is the carrier frame.
Okay crown, firmly sewn
If you need a "Spartan" canopy for the car, the simplest solution will be a frame from varietal metal-rolled pipes of a square or rectangular cross section. In general, it resembles a classic roof construction on racks. The rafting farms are welded from pipes with a cross section of 4020-5030mm. It will be possible without additional backups to block the span with a length of 6m and more. The curvilinear details of the arched roofs are manufactured, flexing pipes along a given radius using a roller machine. The function of the crates is performed by pipes with a cross section of 2020mm, located horizontally in a step of 600-800mm (depending on the thickness of the cellular polycarbonate sheets).
Preparing a place for a snowdrift
The roofs of polycarbonate are always designed in such a way that the snow does not accumulate on them. In the event there will have to increase the number of carrier frames of the frame, and the design will be too expensive. Kschastina, the snow almost does not delay on the smooth surface of the plastic, and so that it rolls, it is enough to give the roof of the slope of only 20-30. That's just where? It is better to arrange a shed so that the drifts are not formed on the tracks leading to the house before entering the site, near the porch or right at the building wall. And the neighbor is unlikely to say you thanks for avalanche, regularly converging on its territory.
Finished design elements are covered with a protective and decorative composition. It is best to carry out the street conditions of powder paints applied in the factory conditions. Ordinary enamels are significantly less than the rack, but this coating costs cheaper and can be updated independently.
Steel frame (racks, farms and "crate") are collected in place using bolts, screws, corners, as well as special fasteners. The step of farms should not exceed 1500mm, otherwise the details of the "crates" can progress under the weight of snow. Applying when assembling, welding is extremely undesirable, because in the seams of the seams the factory protective coating burns out and the metal here quite quickly corrodes.
Today, some manufacturers of metal structures ("empire", "Commander", "MetallmanthService" IDR., All- Russia) The manufacture of autonavissas has become a separate direction of activity. The price of serial products is 52.51.8m, from 19 thousand rubles. (including installation). Natih firms can be ordered by any "non-standard", and the level of service fully meets modern requirements: it will not have to pay for the visits of the measurer, and the project will cost only 2-3 thousand rubles. A number of companies offer to make an aluminum framework - this material is much better than steel, suitable for operation on the street, as it is almost not subject to corrosion. However, the product is almost 2.5 times more expensive than steel. From the finished metal, the strict ventilated farms are well obtained ("A la Waterloo Station"), but decorative openwork elements and sculptural details are harder.

9. Often the garage is located in the basement of the building. At the same time, there is a need to take the flow of rain and melting water from the garage gate. If the groundwater level is low, the roof over the entrance avenue allows you to simplify the drainage system and refuse to install expensive pumps. 10. A quick-spinning gazebo coated from a colored polycarbonate will protect and from the rain, and from the scorching summer sun. Complete delivery includes tables and benches. Price - 6800 rub. 11.12. The carriage of the visor over the porch, as a rule, is performed in one style with railings. At the same time, there are more strict and elegant products made of steel or aluminum profile pipes (11) for emphasized modern buildings (11), while the classical tradition and imitation of antiquity will require an openwork ornament from forged and cast elements (12)
If you want to purchase a canopy or a visor stylized under ancient, it is worth contacting the company offering wrought iron products. It is important that the design provides for the attachment for polycarbonate; This question should be discussed with the designer and the master in advance. Welding or subsequently welded mounting plates will spoil the appearance of the roof.
For the frame you can use both wood, but only glued. Ordinary massive bars and boards will certainly behave. Because of this, polycarbonate sheets will be deformed and crack, and there will be wide gaps and cracks between them.
Flow- in Rodlo
As a rule, sheds from cellular polycarbonate are sold without a drainage system. However, it will not be able to do without it: during the rain, water is spoiled from the eaves along their entire length, and it is soon at the bottom that wins will appear. Vitoga tracks, lawn and flower beds will be spoiled. Therefore, it is better not to save, but mount the gutter and the pipes. PVC products are almost 1.5 times cheaper than metal and no less durable. But for their installation using standard fasteners, special carnisic plates are needed, the presence of which should be specified with the frame manufacturer. The hooks and clamps of the metal drainage system can be attached with the help of bolts directly to the rafter farms.
