Whether Henan fireproof door should be made of wood or steel? I think that many people's understanding of wooden fireproof door is still in the process of questioning whether wooden fireproof door can be safe against fire. There is no need to talk about whether steel fireproof door or wooden fireproof door is better. Usually people subconsciously think that steel fireproof door is better than wooden fireproof door. high quality Fire door According to the Code for Construction Quality Acceptance of Decoration Engineering? GB50210-2001? As far as wood fire doors are concerned, they belong to special doors. Therefore, wood fire doors can not only provide fire safety, but also are widely used in various industrial buildings and some public buildings because of their elegant appearance design, convenient installation and good decorative arts. But it is also beautiful and generous. In the final analysis, what about the wooden fire door with fire safety characteristics? Which is better, steel fire door or wood fire door? Let's have a look at their advantages and differences: wooden fireproof doors refer to those doors whose fire resistance rating exceeds the requirements of GB50045-95? Code for Fire Protection Design of High rise Residential Industrial Buildings with wood or wood handicrafts as door frames, door frame framework drawings, door frame control panels. Fire door Price Wooden fireproof doors are divided into full panel and half glass series products, as well as specifications and models of single and double leaves.

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. high quality Fire door 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. Fire door 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.

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 Price 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.

The installation and installation of Henan fireproof rolling shutter door requires that the fireproof rolling shutter door is widely used in shopping malls, shopping malls and underground garages, but the specific installation steps should not mention laymen. high quality Fire door Even the fireproof rolling shutter door can not be explained in detail. The following is a detailed description of the installation of Henan fireproof rolling shutter door step by step: step 1: install the guide rail. 1. Determine the installation position of the guide rail on both sides of the fireproof rolling shutter door, set out the guide rail reference line with hammer line, and set out the cross line of the fixing bolt of the guide rail connector. The guide rail is not less than 75cm above the ceiling. 2. Punch the holes for fixing expansion bolts of connectors on the wall column with a percussion drill. The spacing between connectors shall not be more than 600mm, and both ends shall be 100mm away from the guide rail opening. Fix several connecting pieces up and down first, stick the guide rail, correct its verticality and spot weld it, and then repeat the verticality of the guide rail after fixing the guide rail. The verticality of each meter shall not exceed 5mm, and the verticality of the whole length shall not exceed 20mm. The depth of the composite curtain embedded in the guide rail (see GBl4102-2005). 3. Install the rest of the connecting pieces. Spot welding shall be adopted between the connecting piece and the guide rail. The spot welding points between each connecting piece and a guide rail shall not be less than 5 points, and the width of the spot welding shall not be less than 5mm. The welding point shall never be penetrated. Fire door Price Stainless steel welding rod shall be used when stainless steel guide rail is used.
