Most people have their suburban plots or private homes within the city, and the variety of building materials and their accessibility makes it possible to embody any ideas. It is no secret that any extension near the house gives it a peculiar appearance, and also plays the role of an auxiliary area. A canopy of corrugated board adjacent to the house will become a convenient space that will be protected from the effects of rainfall and save from the scorching sun. In such a place you can arrange a summer kitchen, a living room, make a recreation area, a game room and even equip a place for a car. In some cases, the canopy can be used for household purposes to store lumber or firewood. The advantage of such a building is the simplicity of the design, which allows you to do it yourself and minimize financial investment. In addition, a profile sheet for roofing is the most suitable option, since the standard slope length is 3 meters and the maximum sheet size is 6 meters. The market offers ready-made sheets of different lengths of 1.5, 2, 3, 3.5 meters, which reduces labor costs and allows you to quickly and easily fix corrugated board on the roof battens.
What is a canopy
By its design, the extension has a uniform way of execution - these are single-pitched canopies. But the execution of such a building can be different, it all depends on the purpose of the space under the roof of the house, the material and the imagination of the owner. There are several construction methods depending on the material used. Supports (drains) can be made of metal or wood. The roofing lathing is made in the same ways. The versatility of corrugated board is that there is no need to adjust the overlap for fasteners, because the edges of the sheet are quite close and this is enough to fix the iron sheet. The perimeter finish is also different. The canopy can be open, wired with a board with windows, polycarbonate, in the form of a terrace, etc.
What to consider before construction begins
At all the will of the owner, but it depends on the functionality and desire of the master, what will be the canopy from the corrugated board adjacent to the house. Calculation in this case is one of the main requirements for determining the required amount of material and accurate assembly at the construction site. If construction involves self-installation, then the implementation of this paragraph must be approached responsibly.
Do not forget about the fundamental part of the canopy, because no matter how lightweight single-shelter canopies are, the additional burden is the snow cover, which in winter can harm the canopy, destroying it with its weight. Also, do not forget about groundwater and the movement of the earthen part with a decrease in temperature, which will also affect the entire structure.
General canopy designs
A canopy of corrugated board adjacent to the house can be made in two ways. This applies to the difference in the fastening of the elements, which will ultimately hold the roofing part. Do not forget about the calculations and the load. If you plan to make a visor from corrugated board over the entrance (porch) or to protect firewood near the house, then you can use braids. This is a design when the emphasis is not on the ground, but on the walls of the main structure. Kosoures are triangles, that is, they work on the principle of holding the shelf for books.
The length of the visor is not more than 1.5 meters, and this is enough to ensure that the design of the kosour is reliable. There is no fear of snow or wind exposure, the canopy, subject to the rules for creating a reliable fastening, will serve its purposes for a long time. When the attached canopy should play the role of a full-fledged structure and have an overhang length of more than 2-2.5 meters, it is necessary to put the support beams perpendicular to the ground with the creation of a solid stop. In this case, there are several ways and methods of construction.
Applicable material and foundation device
If you plan to make a canopy from a professional flooring with your own hands using metal racks, then the best option is to concrete them directly into the ground. You can buy round or square metal. Holes are made under the racks to a depth of at least 80 cm. For this, you can use a shovel, a manual drill or a manual gasoline rig for drilling holes. It is desirable to strengthen the bottom with a solid rock of stone, for example, with crushed stone, so that the rack does not go deep from the weight. It is enough to use metal with a diameter of 50-80 mm, and place at a distance of no more than 1.5-2 meters. It is necessary to make a drawing of the canopy from corrugated board in advance, to calculate the load, design features taking into account the casing or the use of a different decoration to give an appearance. After installation, the crate is assembled so that the structure is given rigidity. After the wells are concreted and left to set.
Using lumber for the construction of a canopy
If the canopy from corrugated board adjacent to the house will have wooden racks, then two installation options can be used. The first involves pinching, that is, the end of the beam or logs are fitted under a metal pipe that will enter the ground. Thus, you can save on the construction of the fundamental part. It is important to note that the pipe should stick out from the ground by at least 15 cm, which will allow the wood in contact with the ground to retain its strength longer. The second design option involves the installation of small nickels on which racks will be installed. For this, a layer of vegetation is cut off and a small depression is made in the area of each rack. Next, a filling is arranged, and a small square of folded brick or monolithic pouring is mounted on top of it. In this case, it is worth relying on the availability of material, abilities and skills. The further order, as with the metal version, is the same. The following actions attach the profile sheet to the crate.
Installation of the rafter system
The structural part of the crate can be made of metal or wood in various ways. Metal design requires a welding machine and skills, so not everyone will go this way. But it should be borne in mind that metal is more reliable than wood, which means it will retain its original characteristics longer. Do not forget that the canopy is an essentially open structure, which means that the environmental impact is obvious. Wood will require constant processing, and joints will weaken over time. At the same time, do not resort to fixing the metal parts of the crate with bolts and angles, only welding is a reliable option in this case. Regardless of the material, the connection of the elements of the rafter system is the same, but has some nuances.
Metal crate
It is carried out by welding products together.
It is necessary to adhere to a pre-compiled drawing in order to prevent improper connection and dimensional imbalance. The crate is a honeycomb, the cells of which are not recommended to exceed more than 50x50 cm. The profile pipe 20x40 mm is mainly used, but with a long overhang, the indicators need to be increased. The main rafters are perpendicular to the walls of the house and are laid along the overhang. Short segments connect the long parts to each other. Thus, rigidity of the entire structure is imparted. It will also be useful to treat the metal surface with a corrosion-resistant coating and paint it. It is better to do this before installing the corrugated board, so that it is possible to apply protection to all areas of the crate.
Wood frame
This technology can be implemented in two ways. If the length of the overhang is small and is no more than 2.5 meters, then there is no need to install connecting (short) segments. It is enough to use the main guide, which is mounted on the edge perpendicular to the wall of the house in the direction of the overhang. The board is used in sizes with a width of 45-50 mm, a height of 80-100-20 mm. The indicators are specified regarding the calculation of the load on the canopy, the length of the overhang and the span. If the canopy from corrugated board adjacent to the house exceeds 2.5 meters, then the bridges between the main rails will be mandatory. Their connection can be accomplished through the use of metal corners or by cutting out the seats and joining each other.
Desired result with the least effort
Summing up, it can be noted that the described material is not inaccessible, expensive, which means that any “arm” owner can make a canopy to his house. It is only necessary not to neglect preliminary calculations, where a special technique can be used to establish the load. To do this, you do not need to study SNiP, it is enough to turn to the specialized literature, where tables and approximate calculations for all regions of the country have already been compiled (an example is in the photo below).
If there is any doubt, then the result of the load can be multiplied by 1.5 and be completely sure of its faultlessness.
In addition, the manufactured corrugated board has a wide range of shades, which will not allow the canopy to spoil the overall appearance of the whole house, but, on the contrary, will give the owner the opportunity to give a peculiar appearance to his dwelling. The main thing is not to neglect the general requirements for working with wood and metal products and to observe elementary safety rules.
