Precautions for Henan fire doors There are many types of fire doors, such as glazed fire doors, stainless steel fire doors, and ordinary steel fire doors. However, the installation methods are basically the same, depending on the site conditions. Some common installation parameters must be noted. 1、 The fire door shall be installed according to the type of fire door used, and the appropriate installation method shall be adopted. 2、 The door frame of the fire door can be fixed with the wall by expansion bolts, or iron parts can be embedded at the opening when building the wall, and welded firmly with the door frame connector during installation. 3、 No matter what kind of connection mode is used between the door frame and the wall, there should be no less than 3 anchor points on each side, and they should be firmly connected. 4、 When installing the fire door, it should be aligned and hoisted. After the size is appropriate, it should be temporarily fixed, corrected and adjusted. The connection and anchorage can be carried out after there is no error. 5、 The sliding door shall be flexible after installation; The side hung door is easy to open and tight and firm to close. 6、 Door closers must be installed on fire doors, and sequencers must be installed on opposite doors. 7、 Hardware accessories such as handle and fire lock on the fire door must be complete; 8、 It is required that the clearance from the ground plane shall not be greater than 5mm. Henan fire door steel fire door is moderate in price, but it is heavy, hard to open, monotonous in style, and not beautiful enough, so it is mostly used in industrial buildings and general grade civil buildings, or parts of buildings that have low aesthetic requirements and low pedestrian flow at ordinary times (such as machine rooms, garages, etc.). major fire resistance steel door On the contrary, wood fire doors have light deadweight, flexible opening and closing, good decorative appearance and many patterns, but their prices are high, and they are mostly used in middle and high grade civil buildings or important occasions in buildings. Generally, the applicable size of large opening for each fireproof door is about 3.3m high, 1.1m wide for single leaf and 3.0m wide for double leaf. In engineering design, in addition to setting fire doors in strict accordance with the occasions, positions, widths, grades and opening directions required by the specifications, attention should also be paid to the fact that fire doors are generally set on the evacuation path (such as stairwells, antechambers, walkways, etc.), and that a little carelessness in the design of building plane details may cause the door leaf to block the evacuation path and reduce its effective width after opening, Violation of basic requirements for personnel evacuation. fire resistance steel door direct deal This phenomenon is particularly prominent at the turning point of the evacuation path and in high-rise residential buildings, which should be paid attention to and avoided.
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 fire resistance steel door 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. fire resistance steel door direct deal 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.
Henan fireproof rolling shutter door is developing rapidly. Henan fireproof rolling shutter door style and measurement design considerations. The fireproof rolling shutter door is widely used in commercial buildings, workshops and underground garages. The specific installation standards are as follows: measurement design: step one: general classification of roller shutter installation. Self inspection of fire shutter: manual operation mode: whether a circular iron chain set in the storage box at one side of the shutter can be found to operate the lowering and rolling. major fire resistance steel door When the installation form is wall side installation: when there are embedded parts (steel plates) in the building, after cleaning the installation datum plane, check and verify whether the size and external position of the embedded parts are suitable for the installation drawing design. If the design requirements are appropriate, this is the datum plane for the installation of large and small supports. fire resistance steel door direct deal The facing bricks around the wall projections shall be cut and matched with the whole brick, and the edges shall be clean. (Check the date of delivery and the date of maintenance; carbon dioxide, dry powder and clean gas extinguishers are outdated if they have been delivered for 5 years or maintained for 2 years; foam extinguishers are outdated if they have been delivered for 3 years or maintained for 1 year, and they need to be sent to the fire extinguisher factory or professional maintenance unit for maintenance). Henan fireproof rolling shutter door After the Henan fireproof rolling shutter door is installed, the ceiling edge should be 50mm away from the curtain plate to avoid friction; c. The foundation dimensions of rolling shutter doors and parts shall be measured, which shall be consistent with the requirements of the design institute.
The main difference between Henan fireproof door and anti-theft door is that the anti-theft door has a good anti prying sealing performance. Generally, the door cannot be opened without a key after closing the door, and the filler in the door panel is not fireproof material. The security door must be marked with "FAM" and refer to the general technical conditions of security door GB17565-2007. Although the fireproof door is also made of steel, the door plate is filled with fireproof materials, and the thickness of the door plate also has different requirements. The steel door is an ordinary steel door. It also has a certain anti-theft function, but its anti prying performance is relatively poor. This type is common in street processing plants. major fire resistance steel door Only Shanghai and Chengdu have local standards for fire and burglar proof doors, and those in other places can only be called fire entry doors, that is, fire doors that reach the standard of fire rated A or B, and (filled with fire door cores) Class A and B standards are generally divided by fire resistance time. At the same time, it meets the anti prying requirements in the following aspects: the door frame is 1.5 thick, and the steel plates on the front and back of the door leaf are 0.8 thick. The lock has the anti prying function, that is, the lock body has both an oblique locking tongue and a square locking tongue. It has the function of quick opening. It is a good twist type, but it is not allowed to install a heaven and earth lock. Locks and cat eyes shall be provided with fire detection reports. Class B fire doors can be fitted with door collars, while Class A fire doors are not allowed. fire resistance steel door direct deal At the time of acceptance, the merchant must provide fire type approval certificate, fire detection report and metal door detection report. Fire detection report of locks and cat's eyes. The door leaf is opened in the direction of rapid evacuation and cannot be opened inward.
