The main difference between Henan fireproof door and anti-theft door is that the anti-theft door has a good anti prying sealing performance. Generally, the door cannot be opened without a key after closing the door. The filler in the door panel is not fireproof material. supply Class A fireproof window The security door must be marked with "FAM" and refer to the general technical conditions of security door GB17565-2007. Although the fireproof door is also made of steel, the door plate is filled with fireproof materials, and the thickness of the door plate also has different requirements. The steel door is an ordinary steel door. It also has a certain anti-theft function, but its anti prying performance is relatively poor. This type is common in street processing plants. Only Shanghai and Chengdu have local standards for fire and burglar proof doors, and those in other places can only be called fire entry doors, that is, fire doors that reach the standard of fire rated A or B, and (filled with fire door cores) Class A and B standards are generally divided by fire resistance time. At the same time, it meets the anti prying requirements in the following aspects: the door frame is 1.5 thick, and the steel plates on the front and back of the door leaf are 0.8 thick. The lock has the anti prying function, that is, the lock body has both an oblique locking tongue and a square locking tongue. It has the function of quick opening. It is a good twist type, but it is not allowed to install a heaven and earth lock. Locks and cat eyes shall be provided with fire detection reports. Class B fire doors can be fitted with door collars, while Class A fire doors are not allowed. Class A fireproof window Price At the time of acceptance, the merchant must provide fire type approval certificate, fire detection report and metal door detection report. Fire detection report of locks and cat's eyes. The door leaf is opened in the direction of rapid evacuation and cannot be opened inward.

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. supply Class A fireproof window 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. Class A fireproof window Price Stainless steel welding rod shall be used when stainless steel guide rail is used.

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.). supply Class A fireproof window 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. Class A fireproof window Price 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.

A brief talk on the problems encountered in the fire acceptance of Henan fire rolling shutter door 1. The curtain plate coating falls off and rusts, and the curtain plate has obvious pressure pits, concave convex, and penetrating holes. supply Class A fireproof window The rolling shutter is a complete fire protection product. If the shutter has problems, it will directly affect the fire resistance limit index of the rolling shutter. 2. The guide rail is deformed and the curtain board is stuck or falls unevenly. The fireproof rolling shutter door generally moves along the guide rail. If the guide rail is twisted or broken, the rolling shutter door will not be able to move to the specified position, which will not achieve the effect of fire separation. 3. On the roller shutter, the lower limit fails or the limit line is wrongly connected. Class A fireproof window Price This often happens on the fire roller shutter of the atrium. Because the fire roller shutter of the atrium is sometimes installed outside the walkway of the upper floor, there is no floor under the roller shutter to close it, and a large gap is leaked, so the fire separation of the upper and lower floors cannot be reached.
