Own business in the field of automotive maintenance requires not only the professionalism of mechanics, but also a competently designed room. Construction of a car service center Today, it is increasingly based on the use of prefabricated structures, among which buildings from sandwich panels are leading. This solution allows to reduce the time of commissioning of the facility from several years to 3-4 months, which is critical for the start of commercial activity.
Designing such a building is a complex engineering process that goes beyond simply buying materials. It is necessary to take into account the load on the foundation, fire safety requirements, the specifics of ventilation and the features of the internal climate, which directly affects the quality of repair of cars. Metal frame In conjunction with modern insulation creates a reliable "skeleton" of the future building, able to withstand operational loads for decades.
In this article, we will discuss in detail all the stages of the project, from the selection of the site to the final finish, so that you can avoid typical mistakes when building an industrial facility.
Before purchasing the first batch of rolled metal, it is necessary to conduct a thorough analysis of the land plot and develop a conceptual scheme for the future service. Architectural design It begins with the definition of the dimensions of the building, which depend on the planned number of service posts and storage space. It is important to understand that savings during the design phase often result in multiple increases in costs during construction or operation.
Geodetic surveys allow you to determine the type of soil, which directly affects the choice of foundation. For lightweight structures of sandwich panels, a columnar or shallowly-deep tape base is often enough, but the presence of observation pits requires a special approach to waterproofing and reinforcement. The load-bearing capacity of the soil should be calculated taking into account the weight of the lifting equipment installed, which can create local loads of up to 5 tons per point.
At this stage, the issue of zoning of the territory is also solved: entry and exit groups, parking for customers, the zone of storage of waste materials and fuel must be clearly demarcated. Errors in the logistics of the movement of cars at the sketch stage can make it impossible for the normal operation of the service in the future.
A modern car service project should provide not only repair boxes, but also comfortable conditions for staff and customers, including reception, waiting area and sanitary facilities. Proper space planning allows you to effectively use every square meter of usable area.
The choice of construction technology directly affects the thermal characteristics of the building and its durability. Frame and metal structures (LMK) are the standard for industrial facilities due to the high strength and speed of installation. The sandwich panels used for the fence consist of two sheets of galvanized steel and a layer of insulation between them, which ensures excellent energy efficiency.
There are two main types of filler: mineral wool and polystyrene foam (PIR/PUR). For a car service with strict fire safety standards, mineral-watt They are the preferred choice as they belong to the class of non-combustible materials. Styrofoam is cheaper and lighter, but requires additional fire protection measures and often does not pass approval with fire inspectors for large areas.
An important aspect is the thickness of the panels. For the central regions of Russia, the optimal thickness for walls is 150 mm, and for roofing - 200-250 mm. This allows you to maintain a comfortable temperature inside the boxes even in severe frosts, reducing heating costs.
In addition, it is worth paying attention to the protective coating of the steel sheet. Polyester is the basic option, but for aggressive environments where chemicals or salts are likely to enter, it is better to choose a coating. PVDF or Puralwhich are resistant to corrosion and fading.
⚠️ Attention: When ordering sandwich panels, be sure to require fire safety certificates and test reports. The use of materials without NG marking (non-combustible) for a car service may lead to a refusal to issue an operating permit from the Ministry of Emergency Situations.
The fundamental basis of any building is its underground part, and the project of a car service center is no exception. Despite the light weight of the metal structures, the requirements for the base are high because of the specifics of the equipment. Lookout holes And lift posts require solid reinforced concrete. The depth of the pit is usually about 1.8-2.0 meters, which requires careful calculation of the groundwater level.
If the water level is high, high-quality waterproofing and drainage system are necessary, otherwise the pit will turn into a pool, and the foundation will begin to collapse. In such cases, often use the technology of "kesson" or raise the floor level, sacrificing the height of the ceiling, but maintaining dryness in the room.
For the installation of double-stack and four-story lifts, the floor must withstand dynamic and static loads. Concrete screed is carried out with a thickness of at least 15-20 cm with the mandatory use of rebar mesh or fibre to prevent cracks.
Also at the stage of flooring, it is necessary to provide a system of oil and gas separators. Spilt technical liquids should not get into the ground, so a special slope of the floor to the ladders connected to the treatment plants is designed.
☑️ Checking the readiness of the foundation
Installation of the frame and paneling is the fastest and most spectacular stage of construction. Columns and farms are installed according to the installation scheme, after which the mounting of wall and roof sandwich panels begins. Additional elements, such as alkalis, ebbs and skates, play not only a decorative, but also a protective function, preventing water from flowing into the joints.
Mounting panels is carried out by special screws with EPDM washers, which ensure tightness of the connection. It is important to observe the mounting step specified in the project so that wind loads do not tear the lining. During installation, you can not allow damage to the protective layer of the metal, as this will lead to rapid corrosion.
Particular attention is paid to the gate. For the car service, sectional or swinging industrial gates with a gate are most often chosen. The openings under them should be reinforced by metal structures of the frame, since the weight of the gate group is significant.
After the installation of the box is completed, the building becomes a sealed contour, inside which you can begin laying engineering networks and finishing work without regard to the weather.
⚠️ Attention: All through utilities (ventilation, electricity, water) must be sealed immediately after passing through the panel. The use of poor-quality mounting foam or sealants can lead to the formation of condensation and freezing of the nodes.
Engineering systems are the “nervous system” of the service, providing its functionality. Ventilation is at the top of the list of priorities, as the removal of exhaust gases and chemical vapors is critical to employee health. Flow-out system must ensure the multiplicity of air exchange in accordance with sanitary standards (usually at least 6-10 volumes of room per hour).
Heating in large volumes of hangar type is most effective to organize with the help of gas or diesel heat generators distributed around the perimeter, or using water heating with radiators under the gate. Electric heating for such areas is economically impractical due to high tariffs.
The power supply requires a separate project with the calculation of loads from compressors, welding machines and lifts. It is often necessary to install your own transformer if the city network is not enough. Three-phase voltage 380V It is the standard for any professional equipment.
Lighting also plays an important role: high-quality diagnostics and painting require high levels of suites. It is recommended to use industrial-type LED lamps with protection from dust and vibration, placing them evenly on the ceiling and additionally highlighting the working areas.
Secrets of energy efficiency of the car service
To reduce heating costs in winter, you can install heat curtains over the entrance gates. They create an air barrier that prevents the blowing of warm air when opening the gates for the car. It is also effective to use heat recuperators in a ventilation system, which transfer heat from the air to fresh supply, saving up to 30% of energy.
The interior decoration and specialized equipment turn an empty building into a working service. Walls in the work area are often lined with panels that are resistant to mechanical damage, or simply painted with wear-resistant paints. Floors in the repair areas are covered with topping or special polymer compositions resistant to oil and gasoline.
The waiting area for customers should be separated from production noise and made in a more cozy style to increase customer loyalty. The presence of Wi-Fi, a coffee machine and a transparent window in the remzone is a modern standard of service.
Installation of lifts, machines for collapse-divergence, compressor and washing equipment is made after completion of all construction work. It is important to comply with technological gaps and requirements of equipment manufacturers when placing them.
The final touch is the improvement of the territory: asphltation of access roads, installation of lighting and signage (signage), which make the object noticeable and attractive to customers.
The financial component of the project requires a detailed analysis, since the cost of construction can vary depending on the selected materials and equipment. Below is an approximate cost structure for a typical car service for 4 posts.
| Item of expenditure | Share in the budget (%) | Note |
|---|---|---|
| Design and harmonization | 5-7% | Including geology and expertise |
| Foundation and floors | 20-25% | Depends on the type of soil and pits |
| Metal frame and sandwich panels | 35-40% | Main volume of material |
| Engineering networks | 15-20% | Ventilation, electricity, heating |
| Equipment and finishing | 10-15% | Lifts, tools, furniture |
It is worth noting that the prices of metal and energy carriers are subject to fluctuations, so the estimate must necessarily be laid reserve fund in the amount of 10-15% of the total amount. Investment attractiveness The project depends on optimizing these costs without losing quality.
⚠️ Attention: Don’t skimp on the engineering network design phase. Errors in calculating the diameters of ventilation pipes or cable cross-sections will lead to the impossibility of full-fledged service and expensive alterations.
Order a sandwich panel at once for the entire facility with a small margin (5-7%). Dosing a small batch later can cause the color of the new batch to differ from the main batch due to different release dates, and the facade of the building will look spotty.
The optimal payback period of a car service from sandwich panels with proper management is 2-3 years, which is much faster than that of capital brick or concrete buildings.
Compliance with the rules and regulations is a guarantee that your car service will not be closed by inspection authorities. The main regulatory documents in the Russian Federation include SNiP, SanPiN and fire safety requirements. Fire-fighting distances The next buildings must be strictly observed, usually at least 9 meters for buildings of I-II degree of fire resistance.
Automatic fire extinguishing systems (often splinter) and alarm systems should be installed inside the room. Exits from the room should be easily opened and lead out. Having an evacuation plan and fire extinguishers in each box is a must.
Environmental standards require the existence of a contract for the export and disposal of waste I-IV hazard class (oil, filters, rags). Drilling oils into sewers or soil is strictly prohibited and entails huge fines.
It is also necessary to take into account the accessibility requirements for people with limited mobility if the service involves visiting customers. Rams and wide doorways should be provided in the project.
Nuances of coordination with environmentalists
When designing a sink, be sure to provide a three-section sump and oil separator. The discharge of even treated sewage into storm sewers without permission is prohibited. The ideal option is a contract with the drainage service for the removal of the contents of the settling tanks, which is confirmed by the relevant acts.
Concluding the review, we can say that the project of a car service from sandwich panels is the optimal solution for a modern business, combining speed, efficiency and functionality. The right approach to the selection of materials, the design of foundations and engineering systems will create a facility that will serve for decades.
The main thing is not to try to save on the key elements of safety and quality of materials, as repairing errors in industrial construction costs much more than the initial construction. Investments in a quality project pay off with stable work and no problems with supervisory authorities.
The implementation of such a project requires a team of professionals: from architects to installers, so choosing a contractor with experience in the industrial segment is a critical step.
What is the minimum space for opening a car service for 1 post?
For comfortable work at one post requires an area of at least 40-50 square meters. This includes the area of the car itself, the area of the master, the placement of the tool cabinet and the necessary stock for safe movement. The ceiling height must be at least 3.5-4 meters for the installation of the lift.
Do I need a building permit for a sandwich panel hangar?
Yes, if the building is capital (has a foundation and is connected to communications), a building permit is required. However, for structures weighing up to 800 kg and an area of up to 50 sq.m. (Some interpretations up to 150 sq.m.) As non-capital structures, the procedure may be simplified before notification. The exact status should be clarified with the local town planning authority.
How long does it take to build such a car?
The average construction time is “turnkey” for a building with an area of 300-500 sq.m. It's 2-3 months. Of these, 2-3 weeks are spent on the foundation, 2-3 weeks on the installation of the metal frame and 2-4 weeks on the installation of panels and engineering networks. The time may be extended due to weather conditions or difficulties with electricity connection.
Can we expand the car service from sandwich panels in the future?
This is one of the main advantages of technology. The metal frame allows you to dismantle the end wall and increase the building in length, adding new spans. The main thing is that the foundation was initially designed for possible expansion or allowed its device without disrupting the operation of the existing service.
