The function effect of Henan fireproof rolling shutter door The fireproof rolling shutter door is based on the steel rolling shutter, the transmission parts are modified, equipped with fireproof electrical appliances and other equipment, so as to achieve the fireproof function: the fireproof motor is controlled by the fireproof electric cabinet, and the roller is driven by the speed change device to make the rolling shutter door open and close. In case of power failure, the manual handle on the fireproof motor can also be used to achieve manual operation. major Steel insulated fireproof window At the relative movement of the machinery, the coupling is used to replace the sprocket drive, and the friction in the track is inlaid with copper plate or nylon. Steel insulated fireproof window Price It is suitable for the use or storage of combustible gases, volatile chemicals and other high ignition materials in factories and warehouses where there is or may be an explosion of fire hazards. 1. The integrated bus is used internally, and the data transmission is reliable and fast. 2. It has the functions of phase sequence automatic detection, correction and phase loss protection. The standby power of main power supply can be switched automatically (with standby power). 3. With rich reserved interfaces, it can be linked with the fire control center. 4. All electronic learning and memory limit, no matter the upper limit or lower limit positioning will never change. 5. It adopts advanced microcomputer processor technology, which is stable and reliable, without upper limit height range 6. It has smoke and temperature sensing signal synchronization and step by step detection function. 7. The setting of operating parameters is simple, convenient and accurate. 8. It has the function of manual priority escape. In case of three-phase power or main power failure, the controller can automatically lower the roller shutter through the quick release device to close the roller shutter.

Why is Henan fire rolling shutter an indispensable facility? Why is fire rolling shutter an indispensable facility. major Steel insulated fireproof window The types of fire rolling shutter doors in Henan mainly include composite steel fire rolling shutter (fire and smoke prevention), inorganic super grade fire rolling shutter (double track double shutter), steel composite water spray steam fog fire rolling shutter, steel composite lateral fire rolling shutter, steel composite horizontal fire rolling shutter, inorganic super grade folding fire rolling shutter and fire rolling shutter with various doors. The fireproof rolling shutter door, as well as the firewall, functions as a horizontal fireproof partition. It is composed of 13 parts, such as shutter, base plate, guide rail, support, reel, box, control box, door rolling machine, limiter, door header, manual quick release switch device, button switch and safety device, and is generally installed at the position that is not convenient for firewall separation. For example, open elevator halls, escalators, wide business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings that cannot use fireproof doors and windows. Fire resisting rolling shutter door has been widely used in building engineering to make fire separation. Steel insulated fireproof window Price Henan fireproof rolling shutter door is an indispensable fire prevention facility in modern high-rise buildings. In addition to the function of ordinary door, the fireproof door has the special functions of fire prevention, smoke separation, suppression of fire spread, and protection of personnel evacuation. It is widely used in high-rise buildings, large shopping malls and other crowded places.

The classification and function of Henan fire rolling shutter door The fire rolling shutter door plays the same role as the firewall in horizontal fire separation. It is composed of 13 parts, such as shutter, base plate, guide rail, support, reel, box, control box, door roller, limiter, door header, manual quick release switch device, button switch and safety device, It is generally installed at the position that is inconvenient to be separated by firewall. major Steel insulated fireproof window For example, open elevator halls, escalators, wide business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings that cannot use fireproof doors and windows.

Henan fireproof door installation method The fireproof door is divided into steel fireproof door and wooden fireproof door according to the material. There are some differences in the installation method of the two fireproof doors. major Steel insulated fireproof window The fire rating is slightly different. You must pay attention to the details when installing. First of all, when installing the wooden fireproof door, the size of the door frame should be 20mm smaller than the opening, and the lower foot of the door frame should be buried 20mm below the ground. The door frame should be firmly fixed with the wall, and perpendicular to the corner. The vertical frame and bracing frame shall be straight and at the same angle to avoid planing and sawing. There shall be no less than 3 fixed points on both sides of the door frame, and the spacing shall not be greater than 800mm. Secondly, during the installation of the steel fire door, considering the bending deformation of the door frame, it is necessary to support the door frame with wooden braces in the width direction of the door frame. The lower foot of the door frame is buried 20 mm below the ground, and then the door frame is welded with the embedded parts on the wall. Then make a hole in the wall at the upper corner of the door frame, and pour concrete of cement, sand and expanded perlite (1:2:5), which can be used after the concrete has set. Steel insulated fireproof window Price Requirements for airtightness of fire doors: there are clear requirements for the size of the gap at each overlap of fire doors: for steel fire doors, the overlap between the leaf and the door frame shall not be less than 10mm, and the gap between the leaf and the door frame on both sides shall not be more than 4mm. The gap after the installation of the fire door cannot be too large, otherwise the airtightness of the fire door is difficult to guarantee, and it is difficult to reflect its role in restraining fire and smoke spread under fire conditions.

A brief talk on the problems encountered in the fire acceptance of Henan fire rolling shutter door 1. The curtain plate coating falls off and rusts, and the curtain plate has obvious pressure pits, concave convex, and penetrating holes. major Steel insulated fireproof window The rolling shutter is a complete fire protection product. If the shutter has problems, it will directly affect the fire resistance limit index of the rolling shutter. 2. The guide rail is deformed and the curtain board is stuck or falls unevenly. The fireproof rolling shutter door generally moves along the guide rail. If the guide rail is twisted or broken, the rolling shutter door will not be able to move to the specified position, which will not achieve the effect of fire separation. 3. On the roller shutter, the lower limit fails or the limit line is wrongly connected. Steel insulated fireproof window Price This often happens on the fire roller shutter of the atrium. Because the fire roller shutter of the atrium is sometimes installed outside the walkway of the upper floor, there is no floor under the roller shutter to close it, and a large gap is leaked, so the fire separation of the upper and lower floors cannot be reached.
