Installation of sandwich panels - a detailed description of the technology and practical tips

use in frame construction sandwich panels significantly reduces the traditional list of interventions - hydro, thermal insulation - which are required in the construction of any buildings.This significantly increases productivity and allows you to complete the work in a short time.However, some simple installation technology - is only apparent.In fact, there are many nuances, without the knowledge of which it is impossible to ensure the reliability and durability.To begin with, you need to consider before starting the installation of sandwich panels.

Compliance features frame size panels

First , increasing the distance between the posts reduce the carrying capacity (load) mounted products.

Second , inconsistency in the selection of optimal size will lead to complication work and increased production of waste, therefore, irrational financial costs.It is therefore necessary to foresee that in the process of mounting the panel had to be cut as little as possible.

All sandwich panels are coated with a polymer-based.Consequently, they are "afraid" of mechanical effects.Rough handling during transportation to the place of work, storage and installation is fraught with scratches to hide that it will be difficult.And to do this it is necessary, not only for aesthetic reasons.Damage to the protective layer leads to the development of corrosion processes which adversely affects not only underneath, usually metal, and an inner heater.

Material surface "lining" of samples

From his choice of instrument depends on the type, which is made (if necessary), cutting boards.

for plastic - any manual (E / jig saw, hacksaw blade with metal), which does not cause heating of the material, which in practice leads to its melting in the incision site.

For steel - tools for cold working.For example, metal scissors "circular saw" (with caution) + the same as for the plastic.Increasing the temperature at the place of cutting is unacceptable, as it leads to melting of the protective polymer layer.

only "cold" method of cutting is recommended for self-supporting insulated panels.

material onto which the installation

depends on this choice of the type of fasteners.On this issue, you can make the following general recommendations:

• concrete - for fixation on such a basis, or apply strong anchor screws with dowels;
• wood - wood screws;
• metal rack - special screws (also called "self-drilling").Previously under them at the base of prepared holes..

Features fixing

• sandwich panels Fasteners must be separated from the edge of not less than 5 cm
• Their installation - vertically at an angle.
• not allowed deformation of the sealing washer (too tight "fit" mounting).Subsequently, this may result in seal failure and leakage.
• necessary to clarify the recommended number of fasteners for one product.The interval between them depends on the specifics of the structure, wind loads, and types of panels attachment method.On average it is 1 m (double-row fixation).

Checking frame geometry

Once the reader is interested in panel mounting technology, then, the general concept of a "skeletal" construction there.No need to go into details of how and what to build himself a "skeleton" of the building.Note Only the main requirement for this design - the correct "geometry".All panels are strictly sustained sizes.Any misalignment of at least one frame member will cause the sandwich panels that fit to each other so as to leave no substantial gap between them (slots) does not turn.So, have their "crop", and at an angle.And it is difficult, and a waste of time.Therefore, before the start of the installation work is needed to make sure that all parts of the structure are strictly "parallel and perpendicular."

Processing cap and bearing elements

Depending on local conditions, apply antiseptic and anti-corrosion agents.If the support frame is built of wood, then additionally made its drenching fire-retardant (ignition).

fastening technology

It makes no sense to paint all the "subtleties" of this work for two reasons.Firstly, we are talking about the sandwich panels in general, and they come in different types.Second, to apply its products manufacturers supporting documentation with the recommendations (instruction manual), in which all the specifics of the installation of these products it is fully reflected.For example, if needed between the guide panels and insulation, and if so, what?To the reader avoid confusion in this matter, we note only the main points, which is characterized by the construction of frame panel houses.

Sort samples

By the way, it often or forget or neglect this phase.For sandwich panels, usually purchased in different sizes (project, drawing), since any structure has its own characteristics.It is in order to minimize the work of cutting (and hence reduce the amount of waste), and selected the appropriate sample size.

Installing the support elements for the bottom row

Their attachment is made to the structure of the cap, along its perimeter.As these guides are used metal profile, area (1 mm), in some cases - wooden slats (lumber).The interval between the fasteners chosen arbitrarily (usually about half a meter).The main thing is to support the fixation was reliable.

necessary to ensure that it is horizontal, otherwise the whole panel "assembly" will go out of alignment.Therefore, building level here - the main "assistant".If desired, the top cap is pre-treated with sealant or between the sealant and the guide is placed.

Mounting Horizontal

From the title it is clear that first, starting from the corner, laid out the bottom row, and then, one after another - all others.It is necessary to maintain the recommended width of the joint (considering thermal strain).The panels are installed in such a process groove downwards.Why, of course - this provides additional protection against ingress of liquid into the sandwich.

Installation vertical

characterized in that the vertical rows are erected after the installation of the lower tier.Yes, and orientation changes as their shape - a rectangle.

installation on the roof

This type of work is largely determined by the steepness of ramps.At an angle of more than 150 it is recommended to install additional stops, protecting the panel from slipping from the roof system.Installation direction - from the edges up to the ridge spans.

final stage - the installation of additional elements.

few comments

• The article gives general guidelines.Therefore, when installing certain types of sandwich panels need to manufacturers instructions.
• «Docking» samples is carried out using special tools (clamping device).Methods such as "let's knock" in this case, may damage the sandwich.
• If you work forces hired experts, you should not rely too much on their integrity, even if someone and spoke about these people well.The fact that they are often "flaws" appear only after some time.And they can be, because to do for someone - this is not one and the same thing for themselves.Hired Wizard "earn" in the first place, to the speed of the installation, and the quality, unfortunately, takes a back seat.From this point of view, you need to fully understand all the nuances of this work and monitor at all stages without exception - so reliable.
