Fire hatch. Fire hatches in the attic and ceiling
Unfortunately, private houses are in the first risk group in terms of fire safety. The reason for this is the common material for construction – wood.
Protecting the lives of households in the event of a disaster is the most important task that can be accomplished design features Houses. One of them is fireproof hatches in the attic. If there is a threat of smoke or impossibility of access to rescue exits, this is The best decision V emergency situation.
Fire hatch - how to install it yourself
The simplicity of the design - a metal frame sealed around the perimeter with non-flammable material and a steel door with automatic latching - also implies ease of installation. As a rule, such access to the attic is additionally equipped with a retractable staircase.
However, considering poor compatibility wood and metal, you will have to carry out a series preparatory work, protecting the natural structure from negative influences steel, or, more precisely, the consequences of its use. So, how to install a fire hatch leading to the attic - instructions for home craftsmen:
- First you need to choose the right factory design. You need to contact specialized companies related to fire safety products.
Specialists will offer the required options. Of these, those that best suit the technical regulations are selected:
- Fire resistance limit from 30 – 60 minutes.
- Steel thickness is from 0.8 – 2 mm. The coating can be specially selected to match the interior, so as not to create dissonance. Models coated with powder paint look good, as do expensive metal doors.
- The box is equipped with a non-flammable thermosetting seal, which, when heated, expands and blocks access to smoke and flame. In quiet times, such a seal will not give drafts the slightest chance - this is especially true if attic space not heated.
- Inside the canvas there are mineral wool or fire-resistant boards. It is worth regularly monitoring the quality of the insulation - cotton mats can cake, then they need to be replaced, otherwise metal structure will become a bridge of cold.
- Closers, handles, locks and other fittings must withstand open flames and not heat up, thereby making it impossible to use. It is possible to install an anti-panic system - a wide handrail with automatic opening and closing.
- As for the issue of parameters - length-width, the fire hatch for the attic can have individual dimensions. You need to proceed from the fact that an adult can easily get into the under-roof space and what kind of staircase will be involved in this. The optimal rectangular shape is 1200 mm × 700 mm.
Separately purchased material for laying between wood and metal box. Well, the corresponding tool is a screwdriver, Circular Saw, fasteners
- Next, markings. Contours should be outlined with allowances of 5-6 cm more exact dimensions. Such gaps will serve as compensation for the continuous shrinkage of the house, which can jam even metal and at the same time crack under its resistance.
It is enough to drive in four nails or fix the screws in such a way that the tip comes out on the other side. There is no need to outline contours on two surfaces at once and then adjust what is needed - then curvature cannot be avoided.
- Then, the freed wood is removed and the resulting hole is put in order. What does it mean?
Like cutting window opening, and the hatch, square or rectangle is processed protective compounds for damage, grooves are selected on opposite sides and sealed with jute. The bare wood is previously covered with a vapor barrier.
- Now they are constructing the box - the fire hatches to the attic are first disassembled into their component parts. A beam with a cross section of 50 mm is installed in the selected groove. You can add a few small blocks under short slats– the resulting expansion gaps must be foamed with a mounting substance.
Then the long parts of the box are attached, followed by the short ones. You should not screw the box tightly - shrinkage will go more smoothly if there are no obstacles to it.
- Next, install the hinges and screw the door, having previously attached fittings to it - a handle or an anti-panic system. All that remains is to foam the expansion gaps and carefully cut off the sloppy protrusions. After this, decorative trims are fixed.
The entire structure is checked by repeated opening and closing, all interfaces and mechanical parts are immediately lubricated. To do this, use silicone grease - it will prevent moisture from penetrating into the moving parts in case of condensation. The material needs to be constantly updated.
The hatch is ready. However, to reach the attic space you will need a ladder. It can be folded, placed on the hatch door, so that in case of danger it can be quickly brought into working condition.
But not to shy away from design and interior wooden house You can make a twisted or straight design. How – more on that below.
Making a simple wooden staircase leading to the attic
Will be needed following materials and tools:
- Support beam 150 mm wide and up to 5 cm thick – 2 pcs.
- The steps are 2.5 cm thick, the number depends on the height of the ceilings and the roll of 45⁰.
- Fasteners - self-tapping screws, anchors.
- Varnishes or other glazing compounds.
The appearance of such a structure will be determined by the steps, so you need to work hard on creating them. They can be asymmetrical protrusions, oval or pedal-shaped.
They are pre-drilled in the right places for fastening, processed and varnished, but they cannot be made slippery. There are special overlays that are glued to the surface of the wood and thereby prevent misfortune. Branded models are equipped with special notches.
The fastening of steps has its own rules - the distance from one to another does not exceed 19 cm. Each step should be fixed in two places to prevent unnecessary load on the area.
For work and beauty appearance use anchors made of yellow metal - a shade similar or close to wood. Install the steps strictly parallel to the floor.
The supports should be installed so that in the event of an emergency, they will not budge even under a load of 150 kg - the optimal weight that a home-made ladder must bear. The ends should not rest directly on the fire hatch of the attic exit - they should be secured to the ceiling. They, like all wood, must be processed and, in order not to deviate from the intended interior, varnished.
Railings or other guardrails on the attic stairs leading up to the fire hatch into the attic should not be pretentious or too bulky. They are created only for the convenience of use by elderly people or children. In case of an emergency, they will speed up the ascent process. The railing supports are fastened frequently - every two pairs of steps.
The rescue of drowning people is the work of the drowning people themselves. This catchphrase fully refers to ensuring own safety. The main threat wooden house is still fire.
After a fire breaks out in one place of the building, as practice shows, the fire begins to spread to other nearby rooms, moving to the upper floors and roof. Among the main ways for the expansion of a fire, in addition to the penetration of flame and combustion products through window and door openings, it should be noted such factors that contribute to the spread of fire, such as hatches leading to the attic or roof, insufficiently securely closed elevator shafts and channels in the walls laid in them with cables. To securely close these openings and provide protection from high temperatures open flame install a fire-resistant product such as a fire hatch.
Such a fire hatch leading to the attic is capable of quite long time prevent fire from entering rafter system or roofing material. It should be noted that a properly closed fire hatch is an almost completely airtight barrier. This prevents smoke from entering carbon monoxide and other combustion products into other adjacent rooms through a ventilation or cable duct, attic floor or elevator shaft.
Design and features of the fire hatch
The most common fire hatch for roof access has a fire resistance level of EI 60, which indicates that this design In case of fire, it will be able to withstand the effects of open flame for at least 60 minutes. In this case, the temperature of the hatch on the side opposite to the fire will not exceed +100 ˚С.
Structurally, such a hatch consists of two metal components with the same fire-resistant properties: the box (frame) and the hatch panel. As a rule, they are made from bent metal sheets with a thickness of at least 1.5-2.0 mm. The empty cavities of the hatch and frame doors are filled with non-combustible basalt (mineral) slabs. To increase the level of fire resistance, they are also impregnated with a special solution. Fire hatches must be equipped with hinges, door fittings and locks that remain operational at high temperatures.
