We tell about the features of the design, forms, types of supports, manufacture of frame and mounted polycarbonate sheets.
In the country house, the porch is usually small and represents a small platform with steps. From the rain and snow, the construction is covered by a canopy. Let's talk about how to make a visor over the porch with your hands from polycarbonate.

Design features
Trump protects the entrance door, steps and railing from rain moisture and dew, prevents formation of land and reduces the amount of snow on the porch. It is impossible to do without this element, and the sooner it will be installed, the better. It is easiest to buy a finished design - such products are sold in building markets, and in profile hypermarkets.
Its base is two cantilever bracket from wrought iron or stamped steel, frost-resistant polypropylene, rarely from aluminum, and a sheet of transparent, semi-arctic or bronze cellular polycarbonate with a thickness of 6-10 mm serves as a coating. Make a visor over the porch with your own hands is easy, it is sold assembly or in the form of a set of details, collecting which in the attached instruction is not more difficult than a table from IKEA. But such models are usually very small (no more than 2.2 m2), and their design is rather modest.
More complex and designs can be ordered in a plumbing workshop or forge or make it yourself. This requires a drawing. When working on it, first of all, it should be decided on the architectural appearance and the principle of fastening.
Select form
The usual canopy over the porch usually makes the scope (with one, two or three straight skates). However, the specificity of the cellular polycarbonate is that it acquires rigidity, being curved perpendicular to the ribs of rigidity. This material is best opposed to loads in arched and vaulted structures. And the straight (flat) rods will require a frequent roaring device, which can spoil the appearance of a visor and in any case will reduce its light transmission. The concept of a canopy of polycarbonate itself implies lightness, openness and smooth bending. If you still need to arrange straight rates, it is better to choose a monolithic polycarbonate with a thickness of 6 mm (we note that the monolithic sheet is better with the loads in the extension).
A simple welded visor will cost 6-8,000 rubles.
Brackets are made of frost-resistant plastic in combination with metal.
Trump with bent elements, price - 6,800 rubles.
Selecting the direction of the skate
With a smooth polycarbonate, snow is perfectly rolled. If you send the scat on the threshold of the porch, in the winter you will often have a shovel to work much. It is also important and the question of security, because the construction of polycarbonate usually do not equip with snowstores (in principle, they can be mounted, but aesthetics will suffer). These are the two main arguments in favor of arranging the skate (skates) away from the steps. So less risk once get a good portion of snow for a temonice, and it will be much easier to clean the input zone.

Opports
The visor can rely only on the wall or additionally on the poles - it all depends on its area and snow loads in a particular area, as well as on the configuration of the main roof.Console
In this case, the product relies only on the wall. Well, if there were logs, beams or other protrusions during the construction of the house box. But usually they forget about them and then carrier farms are attached to the wall with studs, coarse screws, a variety of anchors (we will return to the fastening methods). The console design is not designed for heavy loads, its maximum area is 3 m2, the removal for the wall plane is -1.5 m. Do not mount it if the snow is possible on the vision from the main roof: the risk that fastenings or farms is great: Will not stand the blow of a snowy avalanche.
Console with oblique backups
The general principle here is the same, but the distant corners are not suspended in the air, and also relieve walls through the drives. Such a product in practice can be up to 6 m2 and play the wall plane by more than 2 m.
Support on poles
With this form of fastening on the supports, it is possible not to be afraid of snow, unless the design of the STOPILE and DREAMS is unreared. The design can cover not only a large porch, but also part of the yard. But there is another threat - it is possible to rise in the pillars by frosty powder, which will inevitably lead to distortion of the rafter design and its damage. That this does not happen, pillars should be pushed below the depth of the freezing or use as the base of multi screw piles (intricate clogging pins do not fit, as they can dive into the ground under load). If the porch is attached to the wooden house, not yet given shrinkage, the pillars must be equipped with screw compensators. In a wooden house, the poles are equipped with shrink shrinkage compensators that need to be adjusted in the first years after the construction.
What and how to make a frame visor over the porch
The frame of the simplest nudo-oblique visor like "wing" consists only of farms (brackets), to which a sheet of polycarbonate is fixed on top. Farm pitch should not exceed 600 mm. In more complex structures there are horizontal jumpers - Tsargi. Typically, the frame is collected from steel parts. The modern welding machine and the chameleon mask allow you to make it yourself. At the same time, the main problem is related to the need to bend pipes or corners. There are several ways to do it. The first is bending on the Poppel with a heating gas burner. The second is a device of slots that allow you to give the profile the desired shape according to the template (then the slots are breeding) and, finally, the easiest - bending the arch directly when assembling the carrier farm.Principle of bending arches when assembling farm
First fix one end of the rafted.
Then manually bent it on racks.
And weld the second end.
The tightening should be powerful enough to resist the pressure of the racks.
Fastening to the wall
The optimal method of fastening farms - studs or bolts through the wall. But he is not always simple. For example, if inside the wall is covered with plasterboard or other material, the finish will have to be dismantled. To the wooden (brusade or log) walls, the console model can be mounted with coarse screws from 70 mm long. To walls from monolithic blocks and bricks - bolts with steel anchor-dowels, to foam blocks - special dowels with a length of 100 mm (although in the case of foam blocks, it is still preferably a through fastening). For hollow blocks (ceramzite concrete, paved ceramic, as well as slotted bricks) optimal injectable chemical anchors. Well, in the case of a frame wall, it is necessary to be attached to the frame racks, which are looking for focusing on the outlook (also help climbing the wall and trial drilling).
Selection and installation of the coating for the visor
For a visor, it is better to purchase a cellular polycarbonate with a thickness of 10 mm or a monolithic thickness of 4 mm. If it is possible to drop snow and icicles from the roof of the main building, it is better to increase the thickness of the material, respectively, to 14-16 and 6 mm. Matte and bronze sheets will provide easy shading, transparent skipping light is almost as good as silicate glass.Installation
Polycarbonate expands when heated and narrows when cooled, so the holes for fasteners should be larger than the diameter of the screws at least 3 mm. They are sealed with a transparent or color thermoshab. The optimal step of screws is 25-30 cm; With a larger distance, the canopy may not withstand the storm wind.
