The installation of fire doors: SNiP and installation steps

Installation of door designs are usually made according to the standard scheme with defined and often insignificant deviations from the General installation techniques. Varieties of doors a huge amount, so it is logical that each case will have its own nuances. And this is especially true of special models designed for specific applications insulation and protection. These include and fire doors, metal constructions which, though implemented according to the standard scheme, but also provide for the implementation of a number of additional operations. Moreover, in the implementation of such works can not do without the consent of the legal aspects, since the fire design lies a high responsibility in terms of security.

Do you Need a license to install?

That a technical organization and, in particular, installation of fire safety shall be authorized to engage professionals known to all. But in this case, when analyzing technical requirements for fire safety and the law on licensing many also find a lot of contradictions – for example, in the procedures for the granting of this document. But you should start with the first question, which is particularly interested in privateers, planning to carry out the installation of fire doors – do I need a license at all? Yes, it is required to proceed with the installation only those persons who have appropriate permission. As for the license it gives in the departments of the Ministry. But it is necessary to undergo the course of training, to provide information on available equipment and in some cases to pay legal costs, the amount of which will depend on the region.

Requirements of the building regulations for installation

First and foremost take into account the requirements to the materials used. Although most often used metal structures, sometimes in terms of the inadmissibility of heavy construction can be used with wooden and glass counterparts. Another thing is that in each case the substrate must have a Flammability class not lower than G3. The size of the web should also be borne in mind – depends on them, how durable is the installation of fire doors. SNiP in this case indicate that the thickness should not be less than 4 mm and other parameters are adjusted to the opening individually.

Next are fixed and structural requirements which will be implemented by the installation. For example, to open doors should only be towards the exit. Sometimes it is allowed and the application is constantly open to paintings, but in this case still needs to be integrated with the automatic stopper, if there is a fire. Accordingly, the installation of fire doors with closers and actuators should also include installation of backup power supply.

Preparing the installation

Preparatory operations can be divided into three main groups: the order and the fit of the fabric, the formation of the boxes and cleaning the mounting surfaces of the aperture. As for the paintings, most often of its order on an individual project in accordance with the stated sizes – thus the deviation in parameters must not exceed 5 mm. this is followed by the creation of boxes, which is mounted with a small heat-resistant metal hardware and corners. Accessories selected depending on how the scheme will be run for the installation of fire doors – will he have the drive, the accessory protective elements or other functional devices. The final stage of preparation involves working with aperture. At the junction with the door frame shall be thoroughly cleaned – eliminated paint, plaster and other coatings that can support combustion or have the lack of reliability of the fit to the base.

Event wiring

The installation consists of the following steps:

• Integration of the box into the opening. The unit is embedded and fixed with rigid mounting on brackets or even reinforcing segments, which are welded. Importantly, to preserve the symmetry of the gaps from different angles.
• The next stage is installing the paintings. It is fixed to the box using the anchors and bolts, but with the possibility of adjustment.
• Set of hinges, locking devices and other supporting accessories.

Not in all cases, but, for example, at production facilities requirements to the installation of fire doors include improving box wedges. With regard to the reinforcement that is fire protection, you can apply an insulating heat-resistant coatings, thin panels and even spraying.

Where justified in the use of fire doors?

It would Seem that extra protection from fire always makes sense. Even if high is no threat, to protect themselves from it will not be superfluous. And yet these doors are not as easy to operate as conventional metal. They are heavy, unwieldy and require more space for installation. Therefore, in most cases the installation offire doors are made where you really need it. In warehouses, industrial facilities, industries, chemical laboratories, terminals, etc. Can justify this decision and as part of a private house, but need a good reason – for example, if permanently stored flammable materials or other products with no fire resistant properties.

Conclusion

Fire Fighting – responsible and challenging event, the success of which largely depends on which tools were prepared for him in advance. Windows, barriers, walls and doors in this respect play a key role. It is particularly important the quality of installation of protective structures, which are installed and fire doors. Metal or heat-resistant glass cloth can themselves to keep the fire outside the spread of a long time, but for full security you need to consider and protect accessories. It is desirable that all accessories have been manufactured from incombustible materials and, if necessary, further defended and heat-resistant coatings.
