What are the categories of fire shutters? Fire shutter door material

Fire shutter is a kind of active fireproof divider, generally with steel plate and other metal plates, with buckle or hinged method to form a chain plane that can be wound, usually rolled up and placed in the axle box on the upper mouth of the door and window, when it is put down, in order to prevent the spread of fire from the door and window opening. The fundamental difference between the fire shutter used as a fire partition or fire partition for a building and the general roller shutter in terms of performance requirements is that it must have the necessary combustion performance, fire resistance limit and smoke resistance. Fire shutters are divided into light roller shutters and heavy roller shutters according to the thickness of the curtain panel.

The thickness of the light roller shutter steel plate is 0 5 o·6mm; The thickness of the heavy-duty roller shutter steel plate is 1 5 1 6mm. Heavy-duty roller shutters are generally suitable for firewalls or fireproof partition walls; Fireproof roller blinds can be divided into ordinary steel fireproof roller shutters and composite steel fireproof roller blinds according to the structure of the curtain board. The former is made of a single piece of steel plate; The latter is made of a double sheet of steel with thermal insulation in between.

When replacing the firewall, if the fire resistance limit reaches more than 3 0h, the water curtain protection system can be omitted. The fire shutter is composed of a curtain plate, a roller, a bracket, a guide rail and a control machine. The whole assembly consists of a running balancer, an automatic closing mechanism, a metal cover and a curtain part enclosed in the drum.

Smoke and hot air flow are blocked by curtain panels. There are two ways to roll up the roller shutter: electric type and manual type. Manual types are often controlled by zippers.

The electric roller shutter is to install an electric motor at the rotating shaft, and the motor is controlled by a button, one button can control one or several roller shutter doors, or it can be used for all rolls. Fire shutter is a kind of active fireproof divider, generally with steel plate and other metal plates, with buckle or hinged method to form a chain plane that can be wound, usually rolled up and placed in the axle box on the upper mouth of the door and window, when it is put down, in order to prevent the spread of fire from the door and window opening. The fundamental difference between the fire shutter used as a fire partition or fire partition for a building and the general roller shutter in terms of performance requirements is that it must have the necessary combustion performance, fire resistance limit and smoke resistance.

The fire shutter curtain is lifted and lowered by the transmission device and the control system. It plays the role of fire prevention and fire insulation, and the product has the characteristics of flat and beautiful appearance, novel shape and strong rigidity. Fire shutter doors are widely used in the fire partition area of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property, and are indispensable fire prevention facilities in modern buildings.

It is a kind of movable fireproof separator, generally made of steel plate and other metal plates, composed of buckle rings or hinged methods, usually rolled up in the axle box at the upper mouth of the door and window, and put it down when it is used to prevent the fire from spreading from the door and window opening. Fire shutter is a necessary facility for fire protection in modern buildings, and has been included in the national fire protection code for building and other building design, the main types are vertical steel fire shutter, lateral steel fire shutter, and horizontal steel fire shutter. It is widely used in high-end hotels, restaurants, libraries, theaters, large shopping malls, stations, underground projects and factory buildings, warehouses, garages and other buildings.

According to the type of curtain board, the fire shutter is divided into: ordinary type and composite type. The ordinary type has a variety of functions such as fireproof, smoke-proof, windproof, rainproof, and anti-theft.

The function of the composite type is the same as that of the ordinary type, but the composite type does not need to be protected by a water curtain, which is especially suitable for drought and water-scarce places and water-avoiding places.

The fire shutter door is composed of a curtain plate, a reel, a motor, a guide rail, a bracket, a protective cover and a control mechanism together with the roller shutter whose frame can meet the requirements of fire resistance stability and integrity within a certain period of time. The fireproof roller shutter is mainly used for the wall that needs to be fireproofed, especially when the firewall and fireproof partition wall need to open a large opening due to production and use, and the fireproof door cannot be set up. In the early 80s, the fire protection code for steel fire doors and steel fire shutters (hereinafter referred to as the "high regulations") clearly stipulated the separation area of the fire partition and smoke partition in the building.

The building materials used in the separation and what fire level and type of door are used are discussed in detail, which has very important guiding significance for the engineering design of designers and the engineering audit of fire protection construction personnel.

The material of the fire shutter door is mainly from the material of the track and the door piece, the track material is aluminum-zinc, stainless steel, color coating, galvanized and other materials, the material of the door piece is divided into two kinds of inorganic cloth and steel, the material is different, the characteristics are also different, the inorganic cloth is composed of 4 layers of wire throwing fire blanket, fireproof cloth, decorative cloth and radiation-proof cloth. The inorganic cloth fire shutter door is composed of double layer cord, so it has fireproof and thermal insulation performance, and is mostly installed in the interior of the building for partition use. The steel composite type is composed of steel composite door panel composite fireproof rock wool.

Steel composite fire shutter door is a single layer of curtain board, mostly installed outside the building to play a role in fire protection, there is no requirement for the thermal insulation of steel composite fire shutter door in China, but in Europe steel fire shutter door needs to have thermal insulation performance.

The material of the fire shutter door is steel, composite and inorganic.

Fire shutter door is a kind of fireproof and thermal insulation facilities suitable for large openings of buildings, and the product plays a certain role in the design and installation of technology. Fire shutter door is an indispensable fire prevention facility in modern high-rise buildings, fire door in addition to the role of ordinary door, fire door has the special functions of fire prevention, smoke insulation, inhibition of fire spread, protection of personnel evacuation. The calculation of the area of the fire shutter door shall be carried out in accordance with the national construction project budget and final account standards.

Installation requirements and instructions for use of fire shutter doors.

1. The upper part of the opening of the roller shutter door shall not be equipped with ventilation pipes, water pipes, etc.;

2. After the roller shutter door is installed, install the ceiling, and the edge of the ceiling should be 50mm away from the curtain plate to avoid friction;

3. When debugging and using, it is strictly forbidden to stand at the bottom. Electrical facilities shall not be dismantled without authorization;

4. According to fire management regulations.

5. During the routine fire safety inspection every quarter, the chain lubricating oil of the starting motor must not be missed, which is also an important part of the omission of many property units or fire protection units during the inspection.

The fireproof shutter door is based on the steel roller shutter, the transmission parts are transformed, and the fireproof electrical appliances and other equipment are equipped to achieve the fire prevention effect: the fireproof motor is controlled by the fireproof electric control box, and the roller shutter door is driven by the speed changer, and the hand shaker on the fireproof motor can also be used when the power is off, which can realize manual operation. At the relative movement of the machinery, the coupling is used instead of the sprocket transmission, and the friction in the rail is inlaid with copper plate or nylon.

It is ideal for use in environments where fire hazards occur or may occur in factories and warehouses where flammable gases, volatile chemicals, and other highly flammable substances are used or stored.

1. The internal integrated bus is adopted, and the data transmission is reliable and fast.

2. It has the functions of automatic detection, correction and phase loss protection of phase sequence. The main power backup power can be automatically switched (with backup power).

3. It has a wealth of reserved interfaces, which can be linked with the fire control center.

4. The all-electronic learning and memory limit is absolutely accurate, and the positioning of the upper or lower limit will never change.

6. It has the function of synchronous step-by-step detection of smoke temperature sensing signal.

7. The setting of operating parameters is simple, convenient and accurate.

8. It has the function of manual priority escape. When the three-phase electricity or main power is faulty, the controller can automatically lower the roller shutter through the quick release device to close the roller shutter.

The vast majority of the fire shutter doors used are steel fire shutter doors, bulky, unsightly, the metal friction sound emitted by the shutter up and down is its inevitable shortcomings, and in recent years, a new material on the market made of fire shutter doors has been loved by the majority of consumers, this is the inorganic cloth base fire shutter door or called inorganic special fire shutter door, this kind of shutter is a special fireproof cloth, with the effect of fire resistance isolation, at the same time, light weight, can be made in a large span, with decorative color, beautiful and generous. Inorganic special fire shutter door is also divided into inorganic special double-track double-curtain fireproof shutter door and inorganic special single-track single-curtain fireproof shutter door, which can better meet the needs of users, and its fireproof effect and steel fireproof shutter door are equally excellent, and there are more users to choose from.

But there is no perfect thing in the world, the inorganic special fire shutter door has the advantages of steel fire shutter door, and also has its own shortcomings, that is, the daily maintenance is relatively meticulous, because it is a cloth shutter, easy to break and corrode is its biggest shortcoming, and should also pay attention to waterproof, if soaked for a long time may not be used. Therefore, when we buy fire shutter doors, we must buy them according to their own needs, if it is in an indoor dry environment, it is more suitable to use a cloth base fire shutter door, on the contrary, if it is in an outdoor wind and rain environment, of course, it is more suitable to use steel fire shutter doors.

Fire shutter doors are generally installed in garages, shopping malls, warehouses and other places with large entrances and exits. Its function is to prevent fire and theft. The more common rolling shutter door is the fire shutter door, of course, there are many kinds of materials for the fire shutter door, and the effect of the roller shutter door of different materials is not the same.
