【 Weak current College 】 on "fire door not fire" status and improvement---Power By 【 China power house network 】

Fire door refers to a certain period of time to meet fire resistance stability, integrity and insulation requirements, primarily for building fire partitions firewall openings, stairs entrance hallway, pipes, evacuation, etc., the ordinary wellhead to staff, in the event of a fire can serve to prevent the spread of flame and prevent combustion flue gas flow, and in the air distribution system work when sealing effect. Set the location of the reasonable, select model is appropriate, quality is qualified, management are directly related to fire door fire effect, from the fire door status of the entire industry, fire doors and not fully and thoroughly to fire. 25 December 2000, Henan Luoyang Dong do commercial fire, causing 309 people lost their lives, fire doors do not fire this time fire casualties. How to make fire door play function, the author conducted in-depth research, several immature opinions are for reference only: "fire door not fire" State of the art in evacuation 1, aisles, smoke stairs room or shared room settings before changbishi fire door, use a process to make it always, become "normally open" fire door, in the event of fire, the fire door won't stop smoke fire effects; 2, changbishi fire doors with door closer quality can not be guaranteed, not durable, easy to damage to the door closer, most use hydraulic fire doors open process must not exceed 90 °, 90 ° is door closer cannot normally closed issues; both hydraulic door closer there is another problem is that the fire doors in the open will not be able to use the fast shutdown, shutdown will enable fast afterburning behind closed doors with hydraulic generating reaction, withstand the force of human plus, both the results of the external forces can only be delivered to the door closer of the mounting screw, long-term, repeated action results can only be a door closer is loose and falling off. 3, fire hinge with wooden fire door, door frame connection is not strong, after the connection is loose fire doors could not shut down properly. Current wooden fire door hinge and door leaf, the connection between wood screws are used, it is based on the doors, door frames of wood, used for fire doors made of wood are generally more loose, used wood screw connection weight heavy fire door hinges for loosening occurs sooner or later. 4. fireproof door manufacturing materials. Such as wooden fire-retardant treated wood door does not meet requirements, the wood fire retardant treatment is not required; the interior fill of fireproof materials and design or checking materials do not match, such as rock wool instead of aluminosilicate fibre cotton or filled with shoddy; steel fire doors cancel or thinning fire Board; surface embossing of steel fire doors to reduce the thickness of the insulation. 5. dual fan fire door missing order, order easily confused when closed, the fire doors cannot be closed. Although buildings》 7.5.2, the doctrine of "double fan section 5.4.2, many fans of the fire doors are installation order requirements, but from the actual installation of fire door use process nationwide numerous fire doors are not installation sequence, but only equipped with a door closer, in practical use, if the door is pushed on the inside of it is a door that shuts down only the outside of the fire door, and the inside of the fire doors in the entire fire door would leave a gap, flue gas will follow the gap through the fire doors, fire doors will lose fire prevention features. 2. improved fire door fire performance measures: (a), modify the fire technical specifications and further specification of the application of fire door. 1, in enclosed stairway, smoke, fire stairs and elevator room personnel are frequent Office settings of fire doors, should according to use functions, properties determine the fire door at the restart, the closed state. As for residential buildings can set changbishi fire door, for public buildings, plants should set normally opened fire door may provide for the course of normal use of a personnel through should be normally opened fire doors, the course of normal use only by non-staff, fire and other emergency personnel adopted should adopt changbishi fire door; 2, buildings》 section 7.5.2 stipulates that normally open fire doors should be closed in case of fire and should have its own signal feedback function. In fact, it should also be changbishi fire door fire doors with always the same signal feedback capability, and the feedback signals changbishi fire doors also should be able to reflect the two-door closed order correctly, so that fire control room watchkeeping officers to hold the opening and closing of fire doors, timely on close situation of fire door for processing, on similar door closer is damaged, loose causing fire door hinge cannot maintain the normally closed for repairs, ensure changbishi fire door with fire safety, smoke. (2), modify the fire door industry standards, improving product reliability. In 1993 the GB14101-wooden fire door General technical conditions ", GBl2955-1991 ¡¶ steel fire doors General technical conditions of the law on fire doors of product quality is the quality, production: appearance, Assembly accuracy and precision of the overall strength, etc. Its purpose is to meet the requirements of use as door. Functional requirements are primarily: materials performance and fire-resistant properties, its purpose was once a fire to fire, smoke, this is the installation of fire door of the most important. In material properties: door leaf and door frame filled with heat insulation materials should meet the GB8624-1995 "building materials combustion performance classification of incombustibility class a; locks, hinges, latches and hardware its melting point of not less than 950 ℃; the door frame and the door leaf and door leaf Raphe of seal materials for non-combustibility; fireproof glass fireproof door should not affect the fire resistance performance. These provisions are the fire doors are qualified major general criterion. But now our fire protection design specifications, the industry standard in the following areas for improvement: 1 industry standard double fan the fire doors in sequence with no clear performance requirements, it is recommended that industry standards in order for the installation location, action mode, response time, effective action frequency specific, quantifiable, and turn them into practical specific requirements; 2 for industry standards in the non-fire door door closer product quality standards, no installation methods, strong degree of specific requirements, it is recommended that industry standards in the door closer rallyAnd Gates quality comparison between, and regulating the use of camera specifications; increased door closer installation firm level standard door closer with specific actions, thus ensuring that the fire doors has been instrumental in maintaining good closed state; increase the door closer angle requirements of open, break through the manufacturers themselves determine the 90 ° stereotypes, the fire doors to meet the needs and the needs of the market is used. III. improvement of the fire door production technology and installation methods, improve product quality. 1. selection of fire safety hinge, should use separable, demolition of the hinges, when installing the fire door, which can be fastened, then directly to the door leaf can be inserted into the door frame; 2 fixed hinges, door closer, you should change now with wood screws, in frames, door leaf allow fixed hinge holes, and then matching associated screws, nuts, to the installation site, you can follow the reserved hole for standardized operation, overlaid on the screws, nut it is best to also configure appropriate insulation decoration; 3, determine the use of dual-fan, fan the fire doors in building construction process signal feedback line in reserved, fire door installation unit construction, fire protection engineering and construction units early contact reservations line and control module for fire door installation, commissioning, modify the fire legal provisions to strengthen the fire door use process of supervision and management. Fire door in production, the sales process is a kind of fire protection products, and during a fire facilities, production, sales, existing People's Republic of China Fire Services Act on the supervision and management of specific requirements, and in the use of links there evidently defects, there is a need for improvement: 1, on the use of illegal punishment too light and do not have the minimum binding. Fire doors in the use process as a fire-fighting facilities, should press the Fire Services Act, the first paragraph of article 14, paragraph (5) the provisions of the organs, organizations, enterprises and institutions regularly organized inspection, maintenance, ensuring that healthy, effective, when the organs, organizations, enterprises and institutions to violate the requirements of the FPPA article 43 paragraph 1, the correction can only be ordered, overdue correction of, their supervisors and other direct responsibility personnel, legally imposes the administrative sanction or Department warned. Such a legal provisions in the actual execution only symbolic, none of the units to take seriously, firefighting agencies as law enforcement agencies in the course of actual law enforcement authority is unable to perform, to a fire door or a door closer or a hinge to specialized issued a correction notice shall be ordered, then review, review of unqualified and then processed according to the law, the results can only be legally imposes the administrative sanction or Department warned, punished object on penalties but nothing improper about has nothing to do with their feelings, not only a waste of fire inspectors work time and does not solve the problem, but also seriously affected the fire services act as a legal dignity, it is recommended that you modify this clause cannot effectively fulfil the fire responsibility bodies, organizations, enterprises, institutions and related responsibilities given more appropriate penalties, to promote the practical implementation of statutory duties, enhance their mainstay of fire-fighting work well and a sense of responsibility. 2. use of illegal punishment too slowly, is not conducive to the timely elimination of risks. Fire door as a commonly used fire compartmentation in high-rise buildings, extensive use in public places, its poor due to maintenance, the damage caused by improper use of frequent, especially in today's society, the appearance of large numbers of high-rise residential buildings, fire door sales explode, resulting in fire door problems also showing explosive growth, just find a good use of high-rise building, you'll find the fire door there's normally open, hinge changbishi loosening, door closer is damaged, not sealed, and so on, this problem has serious implications for evacuation and fire protection district, a serious threat to the building's fire safety, if in accordance with existing laws to deal with fire, from inspection, issued a notice of correction to be ordered, a review of the law enforcement process generally takes 3-5 days, with such a long time to solve the problem of enforcement numerous vulnerabilities in a problem, the limitation clearly lagging behind demand, is not conducive to the Elimination of hazards. Proposed amendments to the fire service law article 43 paragraph 1, shall be ordered directly from correction of pre condition, direct punishment procedure, in particular penalties on those responsible for penalties related to supervise the effective discharge of their duties.
