Everyone knows the harm of fire. In addition to the loss of property and the tragic casualties of personnel, only a few of the personnel who died in the fire were burned to death by the fire, and most of them were choked to death or fainted by smoke. According to statistics, among all the deaths in fires, about 3/4 of them were caused by inhaling harmful and dangerous smoke. Therefore, when a fire occurs, in addition to controlling the spread of the fire, it is very necessary to be able to effectively and quickly remove the smoke. Then the necessity of steel smoke curtain is obvious. Steel smoke curtain is a very common fire-fighting equipment. When a fire occurs, it is necessary to effectively separate the smoke and provide precious time for people to escape and evacuate. This type of fire-fighting equipment is directly fixed on the roof. It is not like the movable smoke curtain in the normal safety. It is hidden and will only be lowered when there is smoke in the fire. In our daily life, compared with fire-fighting equipment such as windows and doors, many people know little about this type of steel smoke curtain, but they are good at the function and effect of this type of fire-fighting equipment in fire. In order to let you better understand the steel smoke curtain equipment, let's follow the steel smoke curtain manufacturer Saduqi to understand its function in fire prevention and smoke curtain. Steel smoke curtain is common in large spaces such as shopping malls, office buildings and warehouses. It refers to a smoke curtain partition measure made of non-combustible materials, vertically installed under the building ceiling, load-bearing beams or ceilings, which can form a certain smoke storage space in the event of a fire. In the event of a fire, the steel smoke curtain can effectively block the flow of smoke under the building ceiling and create a smoke storage bin that is beneficial to the smoke exhaust system. The height requirement must not be less than 500mm. Steel smoke curtain is different from fire doors. The steel smoke curtain as the main body directly has the function of fire prevention and smoke curtain. From the principle of the fireproof and smokeproof function of steel smoke curtain, it is relatively simple. Its specific content is that when the smoke exhaust system reaches a certain distance and height, it can effectively prevent the smoke flowing horizontally under the building roof, so as to improve the smoke exhaust system effect in the smokeproof partition. At the same time, the device also has corresponding smoke exhaust system equipment. Under the dual action, it can better play the role of fire prevention and smoke curtain, and play a positive role in ensuring the safety of the people. Steel smoke curtain Where should the steel smoke curtain be installed: 1. Rooms in Class C factories with an area of ​​more than 300 square meters or corridors exceeding 40m. 2. Areas with an area of ​​more than 500 square meters and no natural objects (such as beams) to block smoke must be equipped with smoke curtain. Smokeproof partition 3. The site or location where the exhaust system is set should be divided into smokeproof partitions using smoke curtain, structural beams and partition walls. Smoke partitions cannot exceed the evacuation exit 4. The depth of smoke curtain partitions such as smoke curtain walls cannot be lower than the thickness of the smoke storage bin. For indoor spaces with ceilings, when the ceiling holes are uneven or the opening rate is less than or equal to 25%, the height of the indoor space in the ceiling cannot be included in the thickness of the smoke storage bin. 5. In buildings equipped with smoke exhaust systems, smoke curtain walls and other equipment should be installed at the openings where stairs and escalators pass through the reclaimed concrete floor. 6. The maximum allowable total area and the maximum allowable length of the long side of smoke partitions in commercial buildings and public buildings should meet the requirements. When public buildings use natural exhaust systems, the length of the long side of the smoke partition cannot exceed 8 times the height of the indoor space in the building.

We often see various pipes in areas such as underground parking lots, including pipes for transporting liquids (water, gas, steam, etc.) and cables. These pipes usually need to be passed through the installation site of the smoke curtain. If we do not carry out reasonable blocking during the construction process, it will inevitably become a safe passage for the spread of fire accidents. Therefore, effective blocking measures should be taken to block them. So what are the reasonable blocking measures? Let's follow the steps of Hai'an County smoke curtain manufacturer Saduqi Door Industry Fire Safety to learn more about it! What kind of material is used for smoke curtain to pass through the pipe? The smoke curtain completes the design of the smoke partition of the building by isolating the flow of smoke. The smoke curtain can also improve the actual effect of the smoke exhaust system of each air outlet. It must be made of flame-retardant materials such as thick steel plate and laminated glass, and its installation methods are divided into two types: movable and mobile. The movable smoke curtain is controlled by temperature sensors, smoke detectors or other control systems during a fire. For smoke barriers that need to pass through pipes, the smoke barriers are generally made of movable steel or fireproof cloth materials. The steel materials are made of thick steel plates, and the fireproof cloth is made of flexible silicone rubber fireproof cloth. These two materials are convenient for drilling and passing through the pipes in the basement of the villa. When there are many pipes in the construction of smoke curtain, it is troublesome to install hard fireproof plates or steel smoke barriers to pass through the pipes, so soft plastic flexible smoke barriers are generally used to pass through the pipes. The movable flexible smoke barrier is mainly composed of left and right rail decorative strips, buckles, and fireproof silicone cloth. It is easy to install and pass through the pipes. If it is required to install a movable smoke barrier due to the particularity of the project. For the movable smoke barrier, we can only try to ensure the minimum volume, and then leave as little gap as possible between the pipe and the ceiling for installation.

Fireproof Rolling Shutter Door play the same role as fire walls in horizontal fire separation. They are composed of 13 parts, including curtain plates, seat plates, guide rails, supports, reels, boxes, control boxes, rolling door machines, limiters, door lintels, manual quick-release switch devices, push button switches and safety devices. They are generally installed in places where it is inconvenient to use fire walls for separation. For example: open elevator halls, escalators, large business halls in department stores, exhibition halls in exhibition buildings, and places in buildings with large openings that cannot use fire doors and windows. Fireproof Rolling Shutter Door have been widely used in construction projects to make fire separation. Fireproof Rolling Shutter Door are indispensable fire protection facilities in modern high-rise buildings. In addition to the functions of ordinary doors, fire doors have special functions of fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation. They are widely used in high-rise buildings, large shopping malls and other crowded places.
