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 points, 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.

Henan fireproof door is generally set in the following parts. (1) Close the evacuation staircase to the walkway; Enclose the elevator hall, the door leading to the front room and the front room leading to the walkway. (2) Inspection doors of vertical pipe shafts such as cable shafts, pipe shafts, smoke exhaust ducts, garbage ducts, etc. Henan fire door (3) divides the fire compartment, controls the fire wall and the door on the fire partition of the building area of the compartment. high quality fire-resisting window When it is difficult to set firewall or fire door in the building, fire rolling shutter door shall be used instead, and water curtain shall be used for protection. (4) Code (such as GB50016-2014 Code for Fire Protection Design of Buildings) or partition door with special requirements for fire and smoke prevention. For example, the partition doors of equipment rooms (cylinder rooms, foam stations, etc.) attached with fixed fire extinguishing devices in high-rise civil buildings, ventilation, air conditioning rooms, etc. should be Class A fireproof doors; The door on the partition wall of the basement room where people often stay or there are many combustibles shall be Class A fireproof door; Due to limited conditions, it is necessary to arrange oil fired and gas-fired boilers, oil immersed power transformers, high voltage capacitors and switches filled with oil, etc. in high-rise buildings. The doors on the partition walls of special rooms should be Class A fireproof doors. fire-resisting window Price There are also household doors with special requirements that must be fireproof, such as fire control command center, archives room, valuables warehouse, etc., which usually use Class A or Class B fireproof doors. Fire and burglar proof doors are often used as household doors in high-rise and high-grade residential buildings. GB 12955-2008 Requirements for Fire Resistance of Fire Doors Fire doors are an important part of fire fighting equipment and an important part of social fire prevention. Fire doors should be equipped with fire door closers or door closers that allow normally open fire doors to automatically close the door leaves in case of fire (except for special parts, such as pipeline shaft doors, etc.). That is to say, except for some special parts, such as pipeline well doors, which do not need to install door closers, other parts need to install fire door closers.

The fireproof performance of Henan fireproof door is strong. With the development of the times, the fireproof door made of a kind of wood has played a role in fire prevention after processing. After the emergence of the fireproof door, it has gradually been applied to engineering and civil construction. high quality fire-resisting window Next, the rolling shutter manufacturer will introduce the excellent fire performance of fire doors! In the high-rise and middle residential buildings, fire performance is very critical. As a related fire prevention function, it is better to have a better performance if the commercial house catches fire after installation. During the main use process, the advantages of performance and related fire prevention are also gradually emerging. As long as the fire protection performance is grasped, it is also critical in the safe passage. The key is to comprehensively grasp the advantages of such a fire door. Henan fire door is mandatory in the construction process for fire doors, because it is a kind of safety protection for the public. The quality of this door is very good, and from the appearance, the main thing is to grasp the relevant technology, to better grasp the advantages of this performance, can be used in many buildings, is to get permission, can be better reflected in this fire function.
