What are the functions of the doors of Henan Refuge Room? With the rapid progress of society, in order to improve our fire awareness in life, Henan Refuge Room doors have been used. high quality Fire door So, what are the advantages of this product? Next, let's introduce the door manufacturer of Henan Refuge Room to you. 1、 The basic function of fire shutter is to prevent fire. This is a new type of material. This material has a very high ignition point, so it is not easy to catch fire. It is also very good in use. We can use it with confidence. Such a product can be liked if it performs so well in terms of fire resistance, and its sales volume has also increased greatly. 2、 This product has some effect on thermal insulation, because this material is relatively thick, so there is no problem in thermal insulation. Fire door direct deal We all know that heat preservation is important in winter, and the heat preservation effect of this product can just meet the needs of winter use.

Analysis on the influence of fire resistance time of henan fire rolling shutter door on the coming of fire hazard in building fire protection design, ensuring safe evacuation of personnel is the primary premise of fire protection design, and the important standard of fire safety evacuation is time. high quality Fire door China has made detailed regulations on the setting of evacuation width, evacuation distance, various fire-fighting facilities and other elements in various fire technical specifications. These are hard standards for fire design and review, but in fact, these requirements are not isolated from each other and created out of thin air. They all serve to ensure the safe evacuation of people, The setting requirements in the specification mostly come from the calculation of the fire safety evacuation time, so understanding the fire safety evacuation time is the basis and premise for the design and installation of fire rolling shutter doors. The so-called safe evacuation of Henan fire shutter door refers to the evacuation of people to a safe area before the fire develops to threaten the safety of people, that is, to make the safe evacuation time less than the time of danger, which is the benchmark of evacuation design, and all other design elements should serve this goal. The main factors that can cause danger to people in fire are high temperature, toxic smoke, building structure collapse and so on. The high temperature is mainly caused by thermal convection and radiation. When the air temperature reaches 100 ℃, ordinary people can only endure it for more than 10 minutes. When the temperature exceeds 200 ℃, people will die within 5 minutes. The harmful gases in the smoke mainly include carbon monoxide, carbon dioxide, formaldehyde, acetaldehyde, hydrogen cyanide, etc. The common carbon monoxide content in the air as long as 1%, people will lose consciousness after breathing several times, which will lead to death. At present, a large number of polyethylene, polystyrene and other building materials will produce toxic smoke after combustion. Smoke will not only cause poisoning, but also reduce the visibility of people in dense smoke due to the dimming effect of smoke. When the visibility is less than 0.5m, the moving speed of people is equivalent to the walking speed when they lose their vision. Fire door direct deal Henan fireproof rolling shutter door usually has a fire resistance limit much higher than the time of smoke spreading and flowing, but if flammable and combustible decoration materials are used in the evacuation passageway, it may also burn rapidly.

Henan fireproof rolling shutter door maintenance common faults and treatment methods The fireproof rolling shutter door is constantly applied to large supermarkets, shopping malls, underground garages, workshops and other crowded places. It is inevitable that there will be some small problems that need to be solved. I summarize a few points for your reference. 1、 The fire shutter door does not act: first, check the power supply to see if the power supply air switch of the fire shutter door has power. If there is no power, check the power supply. If there is power, the power indicator of the roller shutter control box should be green at this time. high quality Fire door If the indicator light is not on, then we should check whether the transformer in the control box (the resistance of the transformer is 270 ohms) is burned out. If the power indicator flashes green, it indicates that the power supply may be out of phase. If the power supply is not out of phase, it may be that the standby power board of the control box is burned out; It is also possible that both the power board and the standby power board are burned out. 2、 Henan fire shutter door power supply air switch cannot be pushed up: when delivering the gate, the air switch cannot be pushed up, first check whether there is a problem with the standby board, and the resistance of the output line of the standby board is about 300 ohms. In case of open circuit or short circuit, check whether the motor brake is burnt or whether the spare board is burnt. 3、 The operation button does not work properly: you should first press the Stop key, then press the Reset key, and then press the Up and Down keys. 4、 The indicator lights of the power control box or button panel are all on: at this time, first check whether there is a short circuit in the button line or a button may be pressed to death. If the above phenomenon does not exist, it may be that the chip on the power main board is broken, and then replace the chip. Fire door direct deal Pay attention to wearing the clothes in reverse (that is, the opening faces the opening).

In order to protect life and property in time and effectively in case of fire, the fire door of Henan refuge room adopts double-sided fireproof board according to the fire protection design requirements of high-rise building refuge room, so as to achieve dual internal and external fire prevention treatment. The Class A 1.50h and Class B 1.00h fully meet the fire protection requirements, which can strive for greater rescue opportunities for people in case of fire, Make sure there is enough time for rescue. high quality Fire door The fire door of the refuge room is rarely noticed, but it is related to everyone's life safety. When a fire occurs, the fire protection of the refuge bay i] can play the role of fire isolation, isolating the highly toxic smoke and high temperature outside the refuge bay. Provide shelter for people in high-rise buildings and provide more opportunities for emergency rescue. For residential buildings with a building height of more than 54m, each household shall have a refuge room, and the door of the room shall be straight with Class B fireproof door, and the fire resistance integrity of the external window shall not be less than 1.00h. In terms of the current hardbound house configuration in China, a refuge room will be provided for high-rise buildings above 54 meters- The fire resistance limit of the fire door of the general refuge room is about 1h according to the fire control requirements, so that people can escape into the relatively safe environment of the refuge room within one hour of the fire. In recent years, with the growing development of high-rise buildings, skyscrapers have sprung up, and fire doors in shelters have gradually been recognized. Fire door direct deal In order to meet the requirements of high-end buildings for the fire door of refuge room and the surrounding decoration style. Fire doors in shelters are also new. Style panels are more diverse. It is no longer as rigid and dull as the old fire door.

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.). high quality Fire 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 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.
