Specification for fire shutter doors Operating procedures for fire shutter doors

Fire shutter door is a kind of fire-proof and heat-insulating facility, which is suitable for large holes in buildings. This product has played a certain role in the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil buildings. They can effectively prevent the fire from spreading and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. Next, follow us to learn about the relevant knowledge of the fire shutter door specification!

Code for installation of fire shutter doors

1, the upper part of the shutter door hole should not be provided with ventilation pipes and water pipes.

2. Install rolling doors and ceilings. The ceiling edge should keep a distance of 50 mm from the curtain to avoid friction.

3. When debugging and using, it is forbidden to use the base station. Electrical facilities shall not be dismantled without authorization.

4. According to the fire management regulations, the routine fire safety inspection every quarter must be able to leak the lubricating oil of starting motor chain, which is an important content in the inspection of many property rights units or fire control units.

Fire shutter door function

1, the fire shutter door has the same function as the firewall, and can realize horizontal fire separation. It is composed of curtain, seat plate, track, bracket, scroll, box, control box, door roller, limiter, threshold, manual quick release switch device, button switch, safety device, etc. 13, and is generally installed in a place inconvenient for firewall separation. For example, open elevator halls, escalators, large business halls and exhibition halls of department stores are all in exhibition halls and buildings, and fireproof doors and windows cannot be used at the gate. Fire shutter doors have been widely used in construction projects.

2. Fire shutter doors are indispensable fire prevention facilities in modern high-rise buildings. Fire doors not only have the functions of ordinary doors, but also have special functions of fire prevention, smoke prevention and smoke exhaust, so as to restrain the spread of fire and protect people, and are widely used in high-rise buildings, large shopping malls and other crowded occasions.

Material classification of fire shutter doors

1, fire shutter doors mainly include composite steel shutter doors (fire and smoke), inorganic super shutter doors (double-track and double-curtain), steel composite water jet steam shutter doors, steel composite lateral shutter doors, steel composite horizontal shutter doors, inorganic super folding shutter doors and various shutter doors.

2, according to the material, steel, composite materials, inorganic, etc.

3. Roll up and sideways according to the opening direction. There is no national standard for classification of fire shutter performance. GB 14 102 "General Technical Requirements for Steel Fire-proof Roller Curtains" is divided into ordinary steel fire-proof roller shutters. However, the current implementation standard is GB 14 102-2008 "Fire shutter" standard. Grade 1, fire resistance time 1.50h, F2, fire resistance time 2.0h

Scope of application of fire shutter doors

Mainly used in large supermarkets (hypermarkets), large shopping malls, large professional materials markets, large exhibition halls, factories, warehouses and other public places with fire protection requirements. When a fire breaks out, the fire shutter door automatically descends (downwards) according to the preset program under the control of the central fire control system, so as to prevent the flame from spreading to other areas and win valuable time for fire fighting.

Safety code for fire shutter doors

1. In general, large buildings are equipped with a central fire protection system according to the provisions of the National Fire Protection Law. When there is a fire, the smoke sensor (called smoke sensor) installed on the roof first receives the smoke signal and reports it to the central control system. The central fire control system identifies the power supply of the fire shutter door in the fire area and puts out the fire. The fire shutter in this area is descending at a certain speed.

2. When the roller shutter descends to a position about 1.8m from the ground, stop descending to facilitate personnel evacuation. After the fire shutter door stays in the middle for a period of time, it continues to descend until it is closed. During the installation process, the downwind speed and intermediate residence time of the fire shutter can be adjusted.

3. In some cases, there is no central fire control system in the building, and the fire shutter door is only used to realize the fire control adjustment operation procedure of the fire shutter door through the fire box of the fire shutter door. Doors. In this case, when a fire occurs, the fire signal received by the smoke sensor is directly transmitted to the fire control box of the fire shutter door.

4. In case of power failure, the fire shutter can only be lowered by pulling the chain.

5. The production requirements of fire shutter doors are very high, that is to say, the whole system should be able to withstand the high temperature test of about 1 100 for a period of time. The fire resistance time of fire shutter doors is the main index of fire shutter doors. GB 14 102-93 Fire-resistant time of steel fire-resistant shutter doors under general technical conditions is specified as four-grade fire resistance.

Code for operation of fire shutter doors

1, steel fire shutter is an important fire prevention facility in fire prevention zones in public places. It is an electromechanical fire-proof product with comprehensive performance, so the installed fire-proof shutter should always be in a normal state. In the process of using steel fire shutter, professionals should use and keep special equipment, and have certain basic knowledge of electricity and machinery. In the process of operation and use, the operator shall not leave the operating place without authorization. Pay close attention to the opening and closing situation and implementation. No one is allowed to stand under the shutters when opening and closing. In order to prevent the failure of the travel switch, the shutter is stuck and the motor is blocked.

2. Steel fire shutter with fire partition and fire partition is not often used. In case of fire in this area, shutters should be used effectively. The fire shutter with linkage control and central control center control must be automatically controlled according to a set of control command programs.

3. If any abnormality is found during use, emergency measures shall be taken immediately to cut off the input power supply and troubleshoot. Regular maintenance system shall be established for fire shutter, and the maintenance and records of each shutter shall be made. Long-term shutter, must be kept once every six months. Its content is to eliminate dust, paint and lubricate the sprocket roller chain of transmission parts.

4, check whether the circuit and electrical equipment is damaged, whether the operation is normal, whether it meets the instructions, if damaged or does not meet the requirements, it should be repaired immediately.

The above is a brief introduction to the specifications of fire shutter doors summarized by Bian Xiao. I hope I can help you. Thank you for a month.
