It is the entrance door of civil protection project, and the classification of civil air defense doors is relatively clear, including ordinary single and double protective sealed doors and sealed doors, living threshold single, double protective sealed doors and sealed civil air defense doors and other equipment.
Fire door:
According to the new national standard GB _ 1 955-2008, which was implemented on June 65438+1KLOC-0/2009, an accredited laboratory designated by the Ministry of Economic Affairs passed the fire test of fire doors, and obtained the verification login certificate and authorization mark issued by the Bureau of Standards and Inspection of the Ministry of Economic Affairs, which is called fire doors. The fire door defined by NFPA and IBC codes in the United States is "any combination of fire doors, doors, hardware and other accessories that can provide a certain degree of fire protection for the opening."
main distinction
The difference between a security door and a fire door is that the main function of the security door is to prevent prying and better sealing performance. Generally, you can't open the door without a key outside the back door, and the filler in the door panel is not fireproof material. The security door must be marked with the word "FAM" and refer to the General Technical Conditions for Security Doors GB 17565-2007. Although the fire door is also made of steel, the door panel is filled with fire-proof materials, and the thickness of the door steel plate also has different requirements. Steel doors are ordinary steel doors, which also have certain anti-theft function but poor anti-prying performance. Generally, street processing factories are like this.
Only Shanghai and Chengdu have local standards for fire-proof security doors, and those in other places can only be called fire-proof entrance doors, that is, they have reached the national fire-proof A-class or B-class fire-proof door standards, and the A-class and B-class standards (filled with fire-proof door cores) are generally divided by fire-proof time. At the same time, meet the following requirements for anti-prying:
The thickness of door frame is 1.5, and the thickness of steel plates on both sides of door leaf is 0.8.
The lock has the function of anti-prying, that is, the lock body has both oblique locking tongue and square locking tongue, which has the function of quick opening, preferably twist type, but it is not allowed to install heaven and earth locks.
Lock and cat's eye should have fire inspection report. Class B fire doors can be fitted with knockers, but Class A is not allowed.
At the time of acceptance, the merchant shall provide the fire type approval certificate, fire detection report and metal entrance door detection report. Fire detection report of lock and cat's eye.
The door leaves open in the direction of rapid evacuation and cannot be opened inside.
Wood thermal insulation fire door
This standard specifies the classification, specifications, dimensions, technical requirements, test methods, inspection rules, marks, packaging, transportation and storage of products. This standard is applicable to fire doors with wood or wood products as door frames, door leaf frames and door leaf panels.
The difference between electrically controlled fire doors and ordinary fire doors;
Difference:
Emergency and statistical functions, the system can automatically display the physical location of the designated cardholder on the computer, which is convenient for timely contact.
In case of emergency such as fire, the electrically controlled fire door will automatically open to facilitate escape, and the entrance and exit can also be automatically opened; When there is illegal access, it will automatically call the police;
National standard for wood thermal insulation fire doors
Wood thermal insulation fire door refers to a wooden door with wood or wood products as the door frame, door leaf frame and door leaf panel, and the door leaf is filled with thermal insulation materials or with wood or wood products as the door frame and door leaf. According to requirements, doors with fire integrity and heat insulation can also be installed on the door leaf, and an open window consisting of a door frame and composite fire-proof glass is arranged above the door leaf, and fire-proof hardware fittings are provided.
According to the fire resistance limit, wooden thermal insulation fire doors are divided into three categories: A, B and C, and their fire resistance requirements are 90min, 60min and 30min respectively. Wood used to make solid wood fire doors needs to be dry and flame retardant, and its moisture content should not be greater than 12%. Limited by conditions, the moisture content in the production process should not be greater than the local equilibrium moisture content.
The hardware fittings used for wood thermal insulation fire doors must be fire-resistant hardware fittings. The main hardware fittings are: fire hinges (hinges), fire bolts, fire locks, fire sequencers and fire door closers.
Fire Resistance of Wood-insulated Fire Door During the fire resistance test, the wood-insulated fire door should be able to meet the conditions specified in the standard within the time required for its fire resistance.
① Integrity:
No flame on the back fire surface continues to burn for more than10s;
If cracks, holes or other pores appear on the back fire surface without flame, the combustible materials 20mm~30mm away from these pores cannot be ignited within 10s~30s ~ 30s;
The sample should not collapse.
② Insulation:
When the average temperature rise of the temperature measuring points to be distributed on the solid wood fire door reaches 140℃ or the temperature rise of any temperature measuring point reaches 180℃, it is judged that the heat preservation is lost.
When conducting product conformity inspection on site, the following contents shall be checked:
1, whether the product appearance meets the standard requirements;
2. Whether the product identification meets the standard requirements;
3. Whether the product structure is consistent with the test report;
4. Whether the material of the product is consistent with the test report;
5. Whether the performance parameters of the product are consistent with the test report.
