Modern motorists face the need not just to store the vehicle, but to provide it with reliable protection from aggressive environmental factors. Carport with garage It is an ideal combined solution combining the advantages of covered parking and full-fledged closed boxing. This design allows you to effectively use the land, placing one car inside a warm or cold room, and the second under light shelter.
The construction of the combined structure requires careful planning, since the loads on the foundation and supporting elements are distributed unevenly. Unlike a stand-alone frame-carry Or a simple awning, the combined version creates a single architectural form, which dictates special requirements for design and engineering calculations. Properly designed complex will not only be a reliable storage for equipment, but also an aesthetic addition to the landscape of your site.
In this article, we will discuss in detail all the stages of creating such an object: from the selection of materials to the final finish. You will know what nuances you need to take into account in order to The combined design withstands wind loads and snow cover weight without deformation. Competent approach to construction will save the budget and avoid expensive reworks in the future.
Advantages of Combined Design for Auto
The main advantage of combining the garage and the canopy is functional flexibility. Universality The use of space allows you to place overall equipment, such as minibuses or off-predoronics with a trunk on the roof, under an open visor, while a passenger car can stand inside. This is especially true for families where the number of vehicles exceeds the number of cars in the existing structure.
The economic aspect also plays an important role. The construction of a full-fledged second garage costs much more than the construction of a light extension. Polycarbonate Or metal sheds require less materials and labor. In addition, the combined approach solves the problem of ventilation: while the humidity can accumulate in the closed box, the open part provides excellent air circulation, preventing corrosion of the body.
From the point of view of aesthetics, a single architectural ensemble looks more presentable than disparate buildings. Harmonious design allows you to fit outbuildings into the overall style of the house, using the same roofing materials and color solutions of supports. This increases the total value of the property and improves the visual perception of the site.
- 🏗️ Possibility of placing cars of different sizes in one zone.
- 💰 Significant budget savings compared to the construction of two separate garages.
- 🌬️ Natural ventilation under the open part prevents the formation of condensation.
- 🎨 A single architectural style improves the appearance of the house territory.
Selection of materials: metal, wood or polycarbonate
It is necessary to determine the material at the design stage, since the type of foundation and the complexity of installation depend on this. Metal profile It is the most popular choice due to its durability and durability. The structures of the profile pipe do not rot, are resistant to temperature changes and require minimal maintenance if they are covered with high-quality anti-corrosion paint.
Wood is often chosen to create a cozy atmosphere, especially if the house itself is made of timber or logs. However, glued-bar or larch require regular treatment with antiseptics and flame retardants. Wooden canopies look noble, but their service life in the conditions of the Russian winter is still inferior to metal without proper care.
Polycarbonate as a roofing material has established itself as a market leader. It transmits light, which is important for the illumination of the space during the day, but at the same time reliably protects against ultraviolet light and precipitation. It is important to choose a cellular polycarbonate with a thickness of at least 8-10 mm for regions with snowy winters, as it has a high level of carbon dioxide. impact-resistance and thermal insulation properties.
When choosing polycarbonate, pay attention to the presence of a UV protective layer. Without it, the material will turn yellow and become fragile after 2-3 years of operation under the sun.
The combination of materials allows you to achieve an optimal balance of price and quality. For example, a metal frame with a wooden crate and a roof made of profnat flooring is a classic solution that is easy to assemble with your own hands. Each material has its own installation features that must be taken into account when purchasing components.
Design and calculation of loads
Designing a combined system requires taking into account the difference in loads between the capital part of the garage and the light part of the canopy. Snow load It is a critical parameter for Russian latitudes. If for a garage with a steep roof, snow may not be so terrible, then snowdrifts can form on a canopy or flat roof, creating pressures of up to 200 kg per square meter.
The wind load should be taken into account when calculating, especially if the canopy has a large sailing capacity. Aerodynamic properties designs depend on the angle of slope and the shape of the roof. Errors in calculations can lead to the fact that the light part of the canopy will simply be torn by a gust of wind, damaging the main wall of the garage.
Formula for calculating snow load
For a simplified calculation, multiply the normative value of snow weight for your region (can be found in the SNIP) by the coefficient depending on the slope of the roof. For flat roofs, the coefficient is 1.
It is also important to provide a water disposal system. Rainwater from the roof of the garage and the canopy should not flow chaoticly, blurring the ground at the foundation. Storm sewerage Or organized trough with a pipe - mandatory elements of the project. The table below shows a comparison of the main parameters for different types of structures.
| Parameter | Metal frame | Wooden timber | Combined |
|---|---|---|---|
| Term of service | 50+ years | 20 to 30 years | 40 years. |
| Cost | Medium | High (quality wood) | Low/Mediocre |
| Difficulty of installation | Requires welding | Requires carpentry skills | Medium |
| Gone. | Anticorus (every 5-10 years) | Impregnation (every year) | Combined |
Foundation and preparation of the foundation
Since the garage and the canopy have different weights, the foundation for them should be calculated individually for each part, but at the same time work as a single system. For the main part of the garage is most often used ribbon or a monolithic plate that can withstand the weight of walls and ceilings. Under the light supports of the canopy, a columnar foundation or drill-filled piles are enough.
The critical point is to prevent uneven shrinkage. If the heavy part of the garage sits less than the light part of the canopy, dangerous stresses will occur at the place of their connection, which can destroy the structure. Deformation seam or competent reinforcement of binder elements help to compensate for these soil movements.
☑️ Preparation for the foundation pouring
Preparing the base under the canopy itself is also important. Just pouring a concrete pad ("heel") under the wheels would be the right solution to avoid dirt and puddles. Use of the geotextiles Under the layer of rubble will prevent the germination of grass and mixing of rubble with the soil, ensuring the stability of the coating for many years.
Step-by-step instructions for assembling the frame
Assembly of the metal frame begins with the installation of support pillars. They must be strictly set to the level and temporarily fixed with slanting before final concrete or welding to the embedded parts. Verticality of the pillars - the guarantee that the roof will lie flat and the loads will be distributed correctly.
After the pillars are installed, the trusses or beams of the ceiling are mounted. If the span is large, the use of triangular-shaped farms will save metal and increase the rigidity of the structure. Welds should be cleaned and treated with primer to prevent corrosion in places of thermal exposure.
Welding of metal structures is better carried out in dry weather at a temperature not lower than -10 ° C, to avoid the formation of microcracks in the seams due to a sharp cooling of the metal.
Next is the stage of installing the crate under the roofing material. The step of the crate depends on the type of roof chosen: for the flooring it can be less frequent, for soft shingles, a solid flooring from OSB plates is required. All the elements must be securely fixed, because vibration The wind can weaken the fasteners over time.
Roofing and water flow organization
Installation of the roof is the final stage of construction, which determines the tightness of the entire structure. When working with flooring or metal roofing, it is important to use special screws with EPDM seals that do not rust and fit tightly to the surface. They must be twisted strictly perpendicular to the plane of the sheet.
Particular attention should be paid to the node adjoining the canopy to the garage. This is the most vulnerable place where leaks occur most often. Use of quality sealant and metal slats adjoining will avoid water entering the junction between the new and old roof.
The organization of the drain is mandatory for the preservation of the foundation. Even if water drains to the ground, it should be diverted through a drainage groove or tray, so as not to wash the base of the pillars. In winter, icicles can form on the roof overhangs, so the installation of the snow-cutter Or de-icing systems would be a reasonable investment.
⚠️ Attention: When installing a polycarbonate roof, be sure to close the ends of the sheets with special profiles and vapor permeable tape. If you leave the honeycombs open, condensate will accumulate inside, which will lead to the appearance of mold and loss of transparency of the material.
Frequently Asked Questions (FAQ)
Do I need to legalize the canopy attached to the garage?
Yes, if the garage is a capital structure and the extension changes its architectural appearance or building area. In most cases, light canopies without a foundation (on screw piles) are not required, but it is better to clarify this point with the local administration or BTI, as laws may change.
What is the minimum roof slope required for a canopy?
For profnatsil minimum angle is 8-12 degrees, for metal roofing - from 14 degrees. Polycarbonate can be laid on stingrays from 5 degrees, but for effective self-cleaning from snow and dirt, it is better to do a slope of at least 10-15 degrees.
Can I use the carport as a place to store things?
The open part of the canopy is not intended for long-term storage of things sensitive to moisture and temperature changes. However, it is possible to store garden equipment, boats or building materials seasonally, as long as they are protected from direct rainfall.
How to protect metal from rust in the welding site?
After welding, the seams must be cleaned with a Bulgarian petal circle to a metallic shine, degrease and cover with a primer on rust. Only after drying the soil is applied the finishing layer of paint. This is a standard technology that ensures durability.
⚠️ Note: Do not skimp on the fasteners. Cheap screws without a rubber washer will quickly rust and start to leak, leading to corrosion of the metal underneath and the collapse of the roofing sheet in one season.
