The difference between the security door and the fire door is that the main function of the anti-theft door is to prevent prying, and the sealing performance is better. Generally, after closing the door, the door can not be opened without a key, and the filler inside the door panel is not fireproof material. The anti-theft door must have the "fam" mark, and refer to the general technical conditions of anti-theft safety door (gb17565-2007). Although the fire door is also made of steel, the door panel is filled with fireproof materials, and the thickness of door steel plate also has different requirements. Steel door is ordinary steel door, it also has a certain anti-theft function, but anti prying performance is relatively poor, the general street side processing plant is this kind of.

Only Shanghai and Chengdu have local standards for fire and burglar proof doors, while those in other places can only be called fire-proof door, that is to say, the fire-proof door has reached the national fire-proof class A or class-B fire-proof door standards, and the Class-A and class-B standards (filled with fire-proof door cores) are generally divided into fire-resistant time. At the same time, the anti prying requirements are met in the following aspects:

1. The thickness of the door frame is 1.5, and the Fire retardant chipboard

 thickness of the front and back sides of the door leaf is 0.8

2. The lock has the anti prying function, that is, the lock body has both inclined lock tongue and square lock tongue, and has the function of quick opening. It is the best rotary twist type, but it is not allowed to install the earth lock.

3. Fire detection report shall be provided for lock and cat eye. Door collar can be installed in class B fireproof door, but not in class A.

4. During the acceptance, the business shall provide the fire protection type approval certificate, fire protection test report and metal door inspection report. Fire detection report of lock and cat eye.

5. The opening direction of the door leaf is the fast evacuation direction and cannot be opened inside.

Wood insulated fire door

This standard specifies the product classification, specifications and dimensions, technical requirements, test methods, inspection rules, marking and packaging, transportation and storage of wooden heat insulation fire doors. This standard is applicable to the fire door with wood or wood products as door frame, door leaf frame and door leaf panel.

The difference between electric fire door and common fire door:

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 alarm, the electrically controlled fire door will automatically open to facilitate escape, and the entrance and exit can also be opened automatically; in case of illegal access, the alarm will be automatically given;

National standard of wooden heat insulation fire door

The wooden heat insulation fire door refers to the Fire retardant chipboard which uses wood or wood products as the door frame, the door leaf frame and the door leaf panel, and the door leaf is filled with heat insulation materials or the wood or wood products are used as the door frame and door leaf. According to the needs, the door leaf can also be installed with class a composite fireproof glass and the door frame and a are arranged above the door leaf It is a kind of light window made of composite fireproof glass and equipped with fireproof hardware fittings, which can meet the fire resistance integrity and thermal insulation.

According to the fire resistance limit, the wood thermal insulation fire door can be divided into three categories: Class A, class B and class C. The fire resistance performance requirements are 90min, 60min and 30min respectively. The wood used for making solid wood fire door shall be dried and flame retardant, and its moisture content shall not be greater than 12%. When limited by the conditions, the water content of its production should not be greater than the local equilibrium moisture content.

The hardware fittings used for wooden heat insulation Fire retardant chipboard must be fire-resistant hardware fittings, and the main hardware accessories are: fire-proof hinge (hinge), fire-proof bolt, fire-proof door lock, fire-proof sequencer and fire-proof door closer, etc.

The fire resistance performance of wood heat insulation fire door in the fire resistance performance test, the wooden heat insulation fire door should be able to meet the conditions specified in the standard within the time required by its fire resistance performance.

① Integrity:

1. There is no flame burning continuously for more than 10 s on the back fire surface;

2. If there are cracks, holes or other pores on the back fire surface without flame, the combustibles 20 mm ~ 30 mm away from these pores can not be ignited within 10 s ~ 30 s;

3. The sample should not be collapsed.

② Thermal insulation:

When the average temperature rise of temperature measuring points 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 insulation is lost.
