Installation of sandwich panels. The cost and technology of mounting sandwich panels

Today in the field of construction of prefabricated structuresa very popular sandwich panel. They are used in the construction of frame houses, offices, industrial buildings, sports facilities. The method of use depends on the type of material.

Design Features

Sandwich panels are large three-layeredThe structures, consisting of two sheets of rigid material and the insulation between them. To keep all these components together, they are pressed hot or cold. For the insulation layer, polyurethane foam, mineral wool, expanded polystyrene is used. The outer shell can be made of PVC, fiberboard, metal, ceramics, gypsum board. The metal lining is covered with such polymers as: pural, polyester, plastisol. Coatings have a variety of colors. The technology of mounting sandwich panels allows them to be applied in any areas.

Varieties

There are several types of sandwich panels. They are distinguished by several criteria.

By appointment:

• walled;
• roofing.

By profiling the surface of the panel:

• small-profile;
• smooth-profile;
• trapezoidal;
• grooved.

Regardless of exactly which sandwich panel assembly is being performed, its price depends on the amount of work. The bigger it is, the less the cost of 1 m².

Fastening of sandwich panels

The panel fastening elements are selected independing on the thickness and type of the structure being erected. Usually, self-tapping screws are used for this purpose. To determine the required length, you need to calculate - to the thickness of the panel add a self-tapping drill, the thickness of the frame and the washer.

To protect against damage to the surface of the plate, andalso ensuring the integrity of the structure, fasteners with a rubber gasket are used. Mounting should be carried out carefully, not allowing deformation of the washer. The fastening element itself must be at right angles to the panel.

Installation of wall panels

In order to properly mount the sandwich panels,first of all, it is necessary to study the design and installation documentation. It should contain information on the types of products and options for their layout. Installation of wall and roof slabs is different. Each has its own nuances of attachment. The cost of installing sandwich panels depends on the amount of work and the thickness of the structure.

Wall plates can be installed horizontallyand vertical way. The method and location of the installation depends on the method. Combining methods is not recommended. Installation of sandwich panels is carried out in accordance with the technology.

With the vertical method, the installation is made from the corner by the panel, resting end to end, and the horizontal method involves laying the first row from the base.

To prevent the product from contacting the supportsconstruction, it is necessary to lay a layer of insulation between them. According to the technology, if the length of the panels is more than 4 m, the seam should be 1 cm wide. For smaller dimensions, the joint width is 1.5 cm. The joints of the panel slabs must be tightly connected (especially with vertical mounting).

That the product does not lose its properties, between themlay a layer of insulation. With the horizontal method, this is done simply, thanks to their own weight. To ensure tightness, silicone sealants are used. Docking seams are protected by overlapping of the races. Installation is completed by the additional panel.

How much does it cost to install sandwich panels? Price for 1m²:

• with the scope of work up to 1000 m² - from 280 to 380 rubles, depending on the thickness of the structure.
• from 1000 m² up to 2000 m² - 260-370 rub.

The order of installation of the roof panel

Installation of roofing sandwich panels is carried out inthree main stages. The first is the installation of the first plate and its fixing. The lifting of products is carried out using a special vacuum mechanism. In places of pothaking it is necessary to remove the polyethylene film. Fastening of the first panel is carried out to the rafters or run, which are located near the ridge, and then it is attached to all remaining runs. If the roof slope is more than 12 m, the installation is made from the overhang to the ridge. After laying, check the correctness of the position.

The second stage is the cross-connecting of the product. The lower end of the next panel is cut, attaching it to the run. In doing so, remove some of the unnecessary insulation. After the stripping has been carried out, both panels are connected at the transverse joint. Then a longitudinal lock is performed. Before installing in the lock slot, it is necessary to apply a silicone sealant, and then connect the panels.

The cost of installing sandwich panels decreases with the increase in the amount of work.

When installing roof panels, you should follow these rules:

• Before laying the product, remove the protective film from the underside. Between the panels and the elements of the connection, the angle of inclination should be 5%.
• To avoid deformation of the locks and skewing of the plate, two grippers must be used for joining.
• When assembling the sandwich panels, the sealing tape must be attached outside the beams or girders.
• The type of fastening element, their number and place of fastening of one panel are indicated in the design documentation.

Skate installation

After all the roofingsandwich-slabs, you can lay the inner ridge bar. Free space is filled with foam. If the heater is a mineral wool in the product, the slots are laid with the same material. You can use a special seal for this. Then, profile polyurethane gaskets are installed, to which a sidewall strip is attached from both slopes of the roof. Then again, the polyurethane gasket with the adhesive backing is laid. After that, the skate strap is installed.

On how correctly and correctly it is observedtechnology of mounting sandwich panels, will depend on the strength of the structure. Therefore, during the installation work, attention should be paid to the tool, the quality of the product, the fastening elements and to strictly adhere to the technology of their installation. It is best to entrust the installation of sandwich panels to qualified specialists.
