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-resisting 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, and the width of the spot welding shall not be less than 5mm. The welding point shall never be penetrated. fire-resisting window Price Stainless steel welding rod shall be used when stainless steel guide rail is used.

The classification and function of Henan fire rolling shutter door The fire rolling shutter door plays the same role as the firewall in horizontal fire separation. It is composed of 13 parts, such as shutter, base plate, guide rail, support, reel, box, control box, door roller, limiter, door header, manual quick release switch device, button switch and safety device, It is generally installed at the position that is inconvenient to be separated by firewall. high quality fire-resisting window For example, open elevator halls, escalators, wide business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings that cannot use fireproof doors and windows. Fire resisting rolling shutter door has been widely used in building engineering to make fire separation. fire-resisting window Price Fire resisting rolling shutter door is an indispensable fire prevention facility in modern high-rise buildings. In addition to the function of ordinary door, fire resisting door has special functions of fire prevention, smoke separation, suppression of fire spread, and protection of personnel evacuation. It is widely used in high-rise buildings, large shopping malls and other crowded venues. Classified fire rolling shutter doors mainly include composite steel fire rolling shutter (fire and smoke prevention), inorganic super grade fire rolling shutter (double track double shutter), steel composite water spray steam fog fire rolling shutter, steel composite lateral fire rolling shutter, steel composite horizontal fire rolling shutter, inorganic super grade folding fire rolling shutter and fire rolling shutter with various doors.

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-resisting window 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-resisting window 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.

Maintenance methods and precautions of Henan fireproof door Maintenance methods and precautions of Henan fireproof door: 1. Door leaf and door frame shall be placed horizontally and stacked indoors with backing plates, and the frame and door leaf shall be stacked separately. 2. It is strictly prohibited to store together with acid-base substances. The room should be clean, dry and ventilated. 3. It shall be stored in the room with backup frame and separated from the heat source to avoid thermal deformation. 4. Try to avoid outdoor sunshine for a long time to prevent the fire door from being heated. 5. Keep the indoor air circulation and prevent the fire door from frequent damp. high quality fire-resisting window After splashing with water, wipe it with dry cloth to avoid local expansion. 6. To prevent the fire door from being hit abnormally, it is not advisable to use excessive force or open the door at an excessive angle. 7. It is not allowed to hit the door body with sharp tools and heavy objects to prevent the door body from being sunken, scratched and peeling off the paint film. 8. The concealed bolt of the upper and lower fire door shall not protrude when the door is open, so as not to collide with the door frame, deform or fall off and lose its function. 9. Do not support the door for a long time without closing it, which will damage the door closer and make it lose its function. 10. Do not pull off the fireproof seal, or it will lose its function in case of fire. 11. Check every three months to ensure that the fixing screws of hinges, door locks and door closers are not loose. 12. When the hinge makes abnormal noise, add a few drops of lubricating oil to the hinge shaft. 13. The fire door closer must be replaced in case of oil leakage. fire-resisting window Price Then, the Henan Fireproof Doors and Windows Editor summarized the above contents into the following points, and you must remember! Do not always open: it is prohibited to manually keep the normally closed fire doors set on the evacuation walkway, the front room of the smoke proof staircase or the shared front room open during the use process to become "normally open" fire doors. In case of a fire, such "normally open" fire doors can not prevent smoke and fire; Regular inspection: frequently check the integrity of the fire door, check whether the door closer and sequencer are in good use, whether the fire door can be closed automatically in order, and whether the screws on the hinge and hinge are loose. If damaged, immediately organize maintenance; Decoration: one-sided pursuit of decoration effect, canceling the fire door frame and setting only the door pocket made of ordinary wood, replacing the original frame of the door leaf with other materials, and adding decorative surface layer in a large range, thus damaging the fire retardant coating and failing to achieve fire retardant effect; Regular test: the normally open fire door shall be tested regularly to check whether its self closing control system, door closer, sequencer, release switch and other aspects are easy to use, whether it can effectively perform the self closing function in case of fire, and at the same time, it is necessary to resolutely prevent the random stacking of articles near the normally open fire door.
