of having dressed slowly to fall on rope by above-mentioned window or balcony or build external opening landing, certainly, for guaranteeing the speed of fleeing from, we can design simultaneously one group of one group of two people or one group of three people or many people and descend simultaneously, allow again after decline next group librarian use is slow to fall rope and flee from landing, this has just played continuous lifesaving.Above-mentioned technical scheme also has the following advantages: 1, can be provided with above-mentioned built-in pipe from top to bottom on each window side of house or balcony side, the built-in pipe opening, the slow rope that falls, each window when breaking out of fire like this, the external opening of balcony and exterior wall is all passway for escaping, the people of premises communications centre specially crosses conflagration area and removes to find specific passway for escaping, existing each family can not buy descending lifeline for each window, general one family can buy a descending lifeline or escape apparatus is just fine, so each family generally only has a descending lifeline passway for escaping, just may block escape personnel's escape when parlor or the breaking out of fire of doorway, bedroom, even if there is window on the escape personnel side, when descending lifeline in parlor or another room, but conflagration area has been blocked the escape personnel, therefore the escape personnel just can't take descending lifeline and go escape, and the application's technical scheme can be provided with from top to bottom the slow rope that falls in the built-in pipe that each window is other and balcony is other of every cover premises, all set up passway for escaping at each window and balcony, 2, the quantity that present people buy descending lifeline is few, and main cause is to worry effect and the security performance of descending lifeline, if, by the unified screening of developer descending lifeline, select superior in quality descending lifeline, that user will be more relieved, 3, the quantity that present people buy descending lifeline is few, reason also has the placement of descending lifeline to take up room, during use, descending lifeline will have fixedly part, the decorative effect that affect room is understood in arranging of fixture, and the slow descending device of the application's technical scheme is to be placed on the suitable parts such as roof or refuge story, it does not take the normal usage space of building, the lid that only needs the user to open the outside of body of wall or side or inboard switch box body from window limit or balcony limit during use is pulled out above-mentioned slow rope one or the slow slow rope that falls that falls rope two or circulation of falling in the opening of built-in pipe, the user who needs like this escape slow falls rope one or slow fall rope two or circulation slow falls that rope is fixedly connected with and jumping downwards falls with regard to wearable good safety belt by what grab rope device or adopt other way to put in place with above-mentioned extension, the user just can descend safely and escape under the effect that is arranged on the descending lifeline on roofing layer or refuge story, 4, because the house type in the vertical direction of general house is the same, the window of every layer of house and balcony are unified in the position of vertical direction, so when descending lifeline is arranged on the building surface layer or on refuge story the time, rope extension setting from the top down falls in descending lifeline slow just can meet the even all uses of floors of a plurality of floors, and the technical scheme that the developer just implements the application in the construction stage so just reduces costs than each family's purchase descending lifeline, 5, by developer's unification, daily repair and maintenance work and the management work that descending lifeline also is convenient to descending lifeline is set, thereby guarantee the normal use of descending lifeline, 6, the user connects and uses the fast and safety of slow speed of falling rope during fire, and not needing to install descending lifeline only needs the safety belt of having dressed and be connected and fixed to live in to state to delay to fall rope and jump to fall to getting final product.One of advantage of the application's maximum also is: be at first because descending lifeline is arranged on roofing layer or refuge story, above-mentioned roofing layer or refuge story area are large, allow descending lifeline to be designed to the descending lifeline of large volume, can design the slowing-down structure that multiple protection is higher in the large space of the inside of the descending lifeline due to large volume, this is that current family expenses small size descending lifeline can't be realized, also have descending lifeline or the escape apparatus of current family expenses also to exist usual detection all qualified, the accident but breaking out of fire just meets accident while using, this is that the user is fixed on descending lifeline by the other or balcony of window during due to breaking out of fire, at this moment fire-extinguishing truck is with regard to the floor room water spray of Chang Huixiang breaking out of fire, the frictional force that the injection that the descending lifeline of friction-type runs into water will reduce the descending lifeline internal structure makes slowly to fall speed that rope is drawn out of and be greater than safety speed and cause the accident, same when the room breaking out of fire, can outwards spray flare from window or balcony after fire spread, flame, this also can cause the above-mentioned damage that is fixed on the descending lifeline on window side or balcony side, lost efficacy, this is all the major safety risks that breaking out of fire is used current descending lifeline or escape apparatus to exist, adopt technique scheme just can evade above-mentioned potential safety hazard, this is because descending lifeline is arranged on roofing layer or refuge story, this is not ignition point, descending lifeline can not be subject to the impact of fire, while also having breaking out of fire, the user has dressed safety belt and has been connected and fixed above-mentioned extend to arrange from the top down slow and fallen after rope by window or balcony or outward opening is descended safely, due to the safety speed general control descended 1 meter of per second---1.5 meters, that is to say that the slow rope that falls is to descend with interior speed with 1.5 meters of 1 meter of per second or per seconds, the above-mentioned slow rope that falls adopts steel wire cable or static(al) rope painting to brush fireproof paint, fall rope and be exposed in flame even at this moment slow, because the effect of fireproof paint and the slow rope that falls are that speed with 1.5 meters of 1 meter of per second or per seconds is drawn out of and descends, it is slow that to fall the time of rope in flame very short, flame can not fall rope and causes damage slow, last building now is more and more higher, high-rise building continues to bring out, this just causes the slow rope that falls of current descending lifeline constantly to lengthen, the volume of descending lifeline constantly increases, the model of descending lifeline also must constantly increase, this will inevitably affect descending lifeline manufacturing cost and practicality, and the application's technical scheme just can be evaded this problem, the application can only offer each floor use with a vertical slow rope that falls from top to bottom, no matter which floor breaking out of fire all can be used above-mentioned that root to extend from top to bottom layout from the roofing layer of described building or refuge story slow rope safety decline by the effect of above-mentioned descending lifeline falls.When the application's descending lifeline adopts reciprocating descent control device and slow fall that rope adopts circulation slow while falling rope, fall rope and extend from the top down in the built-in pipe in the outside be arranged on exterior wall inside or exterior wall from descending lifeline the slow of circulation that extend out, built-in pipe is provided with opening at each floor place, the user can use from the slow rope that falls of pulling out circulation in opening, so the capable of circulation or user that alternately offer each floor of rope falls in above-mentioned circulation slow, uses.
