Prefabricated sandwich panel constructions: mounting technology

Prefabricated structures from sandwich panels are buildings that are assembled very quickly, but at the same time they are reliable, multifunctional and economical. It is no accident that such designs are very popular with the arrangement of various garages, hangars or warehouses, which are built for a certain period.

What are the features?

Prefabricated structures from sandwich panels have several advantages:

1. Low cost price.
2. Strength and reliability of power structures.
3. The effectiveness of insulation (for this purpose, polyurethane foam is most often used).
4. Speed of assembly.
5. Small weight of structures in comparison with products made of reinforced concrete.
6. Aesthetic and modern appearance.
7. The volume of the working space.

Designs from sandwich panels are delivered to the facility in ready-made form, where they are assembled. Each element is assigned a specific number, so the entire installation process is carried out in accordance with the wiring diagram. To connect components, high-strength bolted connections are used without welding.

What is being built?

Based on prefabricated structures using sandwich panels, it is possible to build:

• Administrative and office buildings;
• Production departments, buildings, factories and factories;
• Logistics and warehouse complexes;
• Sports facilities;
• Agricultural buildings;
• Shopping and entertainment complexes;
• Catering enterprises, laboratories, hospitals;
• Garages and car washes.

Any prefabricated structures from sandwich panels consist of a number of elements, each of which plays a big role. This is a foundation, a metal frame, enclosing structures and architectural units. Let's consider each element in more detail.

Foundation: The Basis of Foundations

The foundation of any building must be reliable and thoughtful. It is for him to load the building. When using prefabricated structures, you can choose a monolithic, pile or slab foundation. The choice must be made on the basis of what are the engineering-geological and hydro-geological conditions of the site of construction, the structural features of the building, the magnitude of the load that will fall on the foundation.

Most often, prefabricated structures from sandwich panels are built on the basis of an easy foundation, especially if the building will serve a limited time. For example, in the construction of single-story buildings, a simple alignment of the territory on which construction will be conducted is sufficient. If the building will serve from 10 years and longer, then you can use a reinforced concrete slab with a thickness of 200 mm. And the most economical foundation is the belt.

Metal frame

The second stage of installation of prefabricated structures is the installation of a metal frame, which is the skeleton of the building. It is he who guarantees reliability and rigidity of the structure. On the metal frame will be installed fencing structures of walls, roofing systems, windows, doors, beams and various auxiliary components. A steel frame is created, and the joining of the elements is carried out using high quality steel bolts. Modern prefabricated sandwich panel constructions are made on the basis of the following types of base: frame, arched or container.

Walling

As the enclosing structures are facing materials, which remove the walls and roofing system, window and door openings. The fastening of these materials is carried out on the metal frame of the building. Thanks to the possibility of finishing, houses made of sandwich panels (they can also be assembled quickly and qualitatively by their own hands) look aesthetically pleasing and attractive. And the choice of materials depends on what requirements are imposed on the building.

Materials for walls and roofing

The walls and roofing system of prefabricated buildings can be built from the following materials:

• Profiled sheet (galvanized or dyed);
• Three-layer sandwich panels, supplemented with insulation material (mineral wool, polyurethane foam, expanded polystyrene);
• Sandwich-profile, which is assembled on separate elements;
• Brick, foam blocks, which are used alone or in combination with ventilated facades.

The choice of materials for the roof should be paid close attention, since it will be the main load. Competent sealing of roofing elements, insulation, organization of drains - all this will protect the structure from moisture, frost.

How to assemble a car wash

Today in the construction industry, prefabricated structures made of sandwich panels are widely used. A car wash or garage based on such systems are built quickly and meet all modern standards and requirements. These autonomous buildings are erected without a foundation, while the first such building appeared in the late 90's. There are several types of such constructions: prefabricated-block, frame-awning and pneumoframe.

The main document, on the basis of which erect prefabricated structures from sandwich panels, is the project. It displays information about what the building will be like, how many materials will be required for its erection, what kind of work will be on the foundation and other important calculations.

Prefabricated car wash

This construction consists of a prefabricated or welded metal frame, as well as lining materials, which are sandwich panels. The peculiarity of this composite material is in the presence of a double-faced liner and a filler made of heat-insulating material. Such a car wash is being built in several stages:

1. A frame is created, the supports of which are partially buried in the ground or fixed to the surface by anchor bolts. Vertical beams contracted by transverse, after which the formation of the framework of walls, internal partitions is performed.
2. Sheathing is in progress. Fastening of panels is made by bolted connections.
3. Gates, windows, doors are installed. It is best to use lightweight structures, for example, based on plastic or aluminum frames. The gates are sectional or sliding.
4. Internal premises are prepared. Finish should be carried out using moisture-resistant materials that will withstand the effects of moisture.
5. Mounted water and electricity supply systems, sewerage, connects equipment.

Carcass-tent car wash

The peculiarity of such systems is in the possibility of assembly and disassembly. Therefore even prefabricated structures made of sandwich panels b. Y. Will be fully usable. To build a carcass-tent car wash will require a frame of metal beams, guides from fiberglass, which will be attached to the fabric. The peculiarity of the fabric is that it is made of PVC and insulated with extruded polystyrene plates. The assembly is carried out in 4 stages:

1. Is going to the frame. Walls are placed on the leveled ground. First, the installation of spatially-resistant sections is carried out, then internal partitions are put.
2. The canvas is installed. On the beams are fastened the elements of fiberglass with bolts, and the fabric is already stretched on the bottom. The guides are made of elastic and bend-resistant materials, so the designs are robust and able to withstand heavy loads.
3. Insulation is in progress. The most commonly used extruded polystyrene.
4. Internal premises are prepared: finishing is performed, networks are laid, sanitary systems are installed, equipment is connected.

Pneumatic car wash

These prefabricated structures of sandwich panels (the photos presented in the review, confirms the simplicity of the construction process) are built on the basis of a lightweight frame based on metal arcs. Between them are inflated balloons of an arcuate shape. They are created from PVC, resistant to the occurrence of air, and for protection from rainfall are additionally covered with a special PVC linen. This car wash is also built in several stages:

1. The frame is prepared: on the leveled surface, the metal arcs connected from below are mounted. Between the adjacent elements, cylinders are laid, after which the structure is covered with a cloth, and its edges are fastened with slings and eyelets to the frame.
2. Cylinders are inflated. Industrial pumps are used for this. On top of the structure is closed with a warm cloth based on PVC, then the sectional door is hung.
3. The equipment of the resulting room is being equipped.

What are good prefabricated car wash?

First, such buildings can be transported from place to place, if necessary. Since they are built without a foundation, the process of their dismantling and re-installation is simple and easy. Secondly, this procedure is performed quickly. As a rule, a maximum of 3-4 days passes from construction to commissioning. One more day the equipment is being adjusted. Thirdly, the construction of prefabricated buildings is inexpensive: the savings are provided by the lack of a foundation and the need for renting equipment, inviting specialists. Fourthly, garages, car washes, warehouses and other premises can be made in a wide dimension row.

Prefabricated sandwich panel constructions: cost calculation

In order to calculate how much the construction of a fast-erecting garage, car wash, agricultural premise or hangar will cost, several factors need to be considered:

1. Length of the building.
2. The width of the span.
3. Height.
4. The thickness of the walls, the roof.
5. Area of glazing.
6. The area of the openings.

Despite the fact that such buildings are erected quickly and easily, a project can not be dispensed with. Design begins with the fact that the technical task is being formed. Then the primary calculations of the framework are made, to which graphic elements and architectural design are applied. The last stage is the author's supervision. In the architectural part, such elements of the future building as design, dimensions and forms of the facade, general appearance of the structure, structural elements and features are developed.

If a logistics complex is being built, then a logistical scheme is being worked out. It is needed to optimize traffic flow inside the warehouse, and the size of the building, the location of the gate will be calculated by the number and type of goods, the location of cargo corridors. In addition to a typical project, companies offer individual development, which will take into account the wishes of a particular customer to the type of a particular building.
