Description
Technical Field
The application relates to the field of building smoke prevention and exhaust, in particular to an electromagnetic smoke-blocking vertical wall.
Background
The smoke blocking vertical wall is made of non-combustible materials, is vertically arranged below a building ceiling, a beam or a suspended ceiling and can form a smoke blocking separation facility with a certain smoke storage space in case of fire. The fire prevention code of building design GB50016-2006 and the smoke prevention and exhaust code of high-rise civil buildings GB 50045-95 (2005 edition) stipulate: the smoke-resistant partition is preferably divided by a partition wall, a structural beam protruding no less than 500mm below the ceiling, and a non-combustible body protruding no less than 500mm below the ceiling or the suspended ceiling. In engineering design, a multi-purpose structural beam for a room without a suspended ceiling is used as a smoke-blocking vertical wall, and the smoke-blocking vertical wall of the room with the real suspended ceiling is generally attached to the suspended ceiling and protrudes downwards by 500mm. The actual natural smoke exhaust window (port) or mechanical smoke exhaust port is mostly arranged below the smoke blocking vertical wall, which is not favorable for smoke exhaust and smoke prevention. The new national standard GB51251-2017 (hereinafter referred to as new standard) is implemented in 2018, 8 and 1, and according to the standard requirements: when a natural smoke exhausting mode is adopted, the thickness of the tobacco storage bin is not less than 20% of the net height of the space and is not less than 500mm, and when a mechanical smoke exhausting mode is adopted, the thickness of the tobacco storage bin is not less than 10% of the net height of the space and is not less than 500mm; the natural smoke exhaust window (port) and the mechanical smoke exhaust port are arranged in the smoke storage bin, only the indoor clear height is not more than 3 m, and the smoke exhaust port can be arranged at more than 1/2 of the clear height. According to the requirements of new specifications and the design of practical projects, a common building structure beam basically cannot be used as a smoke-blocking vertical wall, the smoke-blocking vertical wall needs more vertical space, and the smoke storage bin needs enough height to ensure the thickness.
The fixed smoke-blocking vertical wall has the advantages of lowest manufacturing cost, indoor use with or without a suspended ceiling, no need of fire control, safety and reliability. However, according to the requirements of new specifications, in order to ensure the thickness of the cigarette storage bin, the fixed cigarette blocking vertical wall needs more sagging heights, and the increase of the sagging height means that more lower space is occupied, so that the evacuation height and the average use space of a room and a walkway are often influenced, therefore, when the floor height is low, the use of the fixed cigarette blocking vertical wall is severely limited, and meanwhile, the improper selection of the material of the fixed cigarette blocking vertical wall can bring very adverse influence on the indoor space effect; electronic fender cigarette hangs down the wall and generally needs the real furred ceiling installation of cooperation, the curtain formula keeps off the cigarette and hangs down the wall and is similar to the fire prevention roller shutter, at ordinary times in the reel, does not influence the furred ceiling height, can manually or electronic opening during the conflagration, form the cigarette storage bin, the flagging height can be selected according to the design needs, can the fixed defect that keeps off the cigarette and hang down the wall of effectual solution, but the cost is high, needs fire control power supply control simultaneously, need often overhaul the maintenance, in case lack of the maintenance, just easily take place the condition of inefficacy when the conflagration takes place. The flap type smoke-blocking vertical wall is usually arranged by attaching a suspended ceiling, and hangs down in case of fire, so that the use in ordinary times is not influenced, but a spray header, smoke feeling, an illuminating lamp and the like of the suspended ceiling can be blocked, and the decoration is also difficult, so the flap type smoke-blocking vertical wall is rarely adopted in engineering; the suspended smoke-blocking suspended wall is contracted in a suspended ceiling at ordinary times, and is suspended in a fire disaster, so that the ordinary use is not influenced, but a pipeline cannot penetrate through the suspended ceiling, and the installation requirement is contradictory to the actual engineering, so that the suspended smoke-blocking suspended wall is rarely adopted in the engineering.
In engineering application, the fixed smoke-blocking vertical wall and the electric smoke-blocking vertical wall are limited in use, and the electric smoke-blocking vertical wall has the problems of high manufacturing cost and poor reliability.

The thickness that the during operation can effectual increase storage tobacco storehouse reaches the electronic cigarette and hangs down the same function of wall, can replace electronic cigarette in engineering application and hang down the wall. And, it adopts a common electromagnetism principle, through making the internal coil circular telegram produce magnetic force, through electromagnetism suction strip 15, will contact the activity fire proof board 2 on electromagnetism suction strip 15 surface and tightly hold, after the coil outage, the magnetism of electromagnetism suction strip 15 disappears and realizes the demagnetization, and the activity fire proof board 2 that adsorbs after the adsorption affinity disappears drops automatically, increases the flagging length of keeping off the cigarette hanging wall to satisfy the requirement of new norm to the storage cigarette storehouse. And after the power is switched on, the electromagnetic absorbing strip 15 absorbs the top of the movable fireproof plate 2, so that the use height of the lower part is not influenced, and the functional arrangement of a spray header, smoke sensation and the like is also not influenced. When fire occurs, after the common power supply is cut off, the adsorption function of the electromagnet disappears, the movable part automatically hangs down, the height of the actual electromagnetic smoke-blocking vertical wall is twice of that of the movable smoke-blocking vertical wall, and the thickness of the smoke storage bin is effectively increased.
