Use in the frame construction of sandwich panels significantly reduces the list of traditionally held activities - hydro, thermal insulation - which are mandatory for the erection of any structure. This significantly increases productivity and allows you to complete the work in a short time. However, some simplicity of mounting technology is only apparent. In fact, there are many nuances, without knowledge of which it is impossible to ensure the reliability and durability of the design. Let's begin with that it is necessary to take into account before the installation of sandwich panels.
Correspondence of the framework features to the dimensions of
panels Firstly, , increasing the distance between racks reduces the load-bearing capacity of the mounted products.
Secondly, , a discrepancy in the choice of optimal sizes will lead to more complicated work and increased production waste, hence, unsustainable financial costs. Therefore, it is necessary to anticipate in advance that during the installation of the panel had to cut as little as possible.
All sandwich panels have a polymer based coating. Consequently, they are "afraid" of mechanical influences. Inaccurate handling of them during transportation to the place of work, storage and installation is fraught with scratches, which will be difficult to hide. And this will have to be done, not only for aesthetic reasons. Damage to the protective layer leads to the development of corrosive processes, which adversely affects not only the underlying metal, but also the internal insulation.
Material of external "cladding" of
samples. Depending on its type, the choice of the tool, which makes( if necessary) the cutting of panels, depends.
For plastic - any manual( el / jigsaw, hacksaw with a cloth for metal), which does not cause heating of the material, which in practice leads to its melting in the place of the cut.
For steel - a tool for cold processing. For example, scissors for metal, "circular"( with extra care) + the same as for plastic. Increasing the temperature at the cutting site is unacceptable, as this leads to a melting of the protective polymer layer.
For SIP panels, only a "cold" cutting method is recommended.
Material for mounting
The choice of the type of fasteners depends on this. On this issue, you can give the following general recommendations:
- concrete - for fixing on this basis, use anchors or powerful screws with dowels;
- wood - wood screws;
- metal slats - special screws( they are called "self-drilling").Preliminary under them in the preparation of holes.
Features of fixing sandwich panels
- Fasteners must be at least 5 cm from the edge.
- Their installation is strictly vertical, without any distortion.
- Do not deform the sealing washer( too tight "fit" fasteners).Subsequently, this can lead to depressurization and leaks.
- It is necessary to specify the recommended number of fasteners for 1 product. The interval between them depends on the specifics of the structure, the wind load, the type of panel and the method of attachment. On average, it is 1 m( with two-row fixation).
Checking the geometry of the frame
Once the reader is interested in the technology of mounting panels, then the general concept of "frame" construction is available. Therefore, it makes no sense to go into details, how and from what to build the "skeleton" of the building itself. We note only the main requirement for this construction - the correctness of the "geometry".All panels have strictly consistent dimensions. Any skewing of at least one element of the skeleton will cause the sandwich panels to be adjusted to each other so that there are no significant gaps between them, it will not work. Hence, they will have to "cut", and at an angle. And this is difficult, and a waste of time. Therefore, even before the installation work, you need to make sure that all parts of the structure are strictly "parallel and perpendicular".
Machining of plinth and bearing elements
Depending on local conditions, antiseptic and anticorrosive agents are used. If the supporting frame is constructed of wood, then it is additionally impregnated with flame retardants( from ignition).
Fastening technology
There is no point in painting all the "subtleties" of this work for two reasons. Firstly, we are talking about sandwich panels at ALL, but they come in different forms. Secondly, the manufacturers attach the accompanying documentation with recommendations( instructions, manual), which completely reflects the specific nature of the installation of these products. For example, do you need a heater between the rails and panels, and if so, which one? So that the reader does not have any confusion on this issue, let us just note the main points that characterize the erection of frame panel houses.
Sorting samples
By the way, this is often forgotten or neglected by this stage. After all, sandwich panels, as a rule, are purchased in different sizes( according to the design, the drawing), since any structure has its own characteristics. In order to minimize the work on cutting them( and therefore, to reduce the amount of waste), and the appropriate dimensions of the samples are selected.
Installation of support elements for the lower row
. Their fastening is made to the base of the structure, along its perimeter. As such guides use metal profile, corner( thickness of 1 mm), in some cases - wooden slats( bar).The interval between the fastening elements is chosen arbitrarily( usually about half a meter).The main thing is that the fixation of the support is reliable.
It is necessary to ensure its horizontal, otherwise the entire panel "assembly" will go with a skew. Therefore, the building level here is the main "helper".If necessary, the top of the socle is pretreated with a sealant, or a seal is placed between it and the guide.
Installation horizontal
From the name it is clear that first, starting with the corner, laid out the bottom row, and then, one after another - all the rest. It is necessary to maintain the recommended joint width( taking into account the temperature deformation).Panels with this method are set by the HOLE DOWN.Why, it is understandable - this provides additional protection from liquid ingress into the sandwich.
Mounting vertical
It differs in that after the installation of the lower tier rows are erected vertically. And the orientation is changing, because their shape is a rectangle. 
Mounting on the roof
This type of work is largely determined by the steepness of the skates. At an angle of more than 150 it is recommended to install additional stops that protect the panels from slipping off the rafter system. The direction of laying - from its edge upwards, to the ridge span.
The final stage is the installation of additional elements.
Some remarks
- The article gives general recommendations. Therefore, when installing a certain type of sandwich panels, follow the manufacturer's instructions.
- "Docking" of samples is done using special devices( clamping devices).The "let's knock" method in this case can damage the sandwich.
- If the work is done by hired professionals, then do not rely too much on their decency, even if someone spoke of these people well. The fact is that often their "flaws" appear only after a while. And they can be, as doing for someone - it's not the same thing for yourself. Hired masters "earn", first of all, at the speed of the installation, and quality, unfortunately, recedes into the background. From this point of view, it is necessary to fully understand all the nuances of this work and carry out control at all stages without any exceptions - so it is more reliable.
