Abstract

The utility model discloses a high building quick escape channel, which includes a cylindrical channel body going through a building or a structure; the channel body consists of built-in striking pipes, escape entrances on the floors and communicated with the striking pipes and escape exits on the ground and communicated with the striking pipes. A plurality of striking pipes are arranged in parallel and lined in the multi-head spiral shape around a central axial line which is vertical to the ground. Because the utility model forms a plurality of pipe-like spiral ramps, has a plurality of entrances and large space in the pipes, a plurality of escapers can slide down in parallel, and all the escapers from a high building can be safely evacuated in a few minutes.

Description

High-speed life-saving channel for high building

The utility model relates to a kind of escape device for high-rise buildings, especially a kind of slow lowering pipe escape device.

Progress and The development in society and economy along with science and technology, the urban skyscraper is more and more, many houses, shop, office, dining room, public place of entertainment are arranged among the high buildings and large mansions, in case when sudden disaster such as fire, earthquake, blast occurring, how the stranded crowd of rapid evacuation reduces the important topic that injures and deaths are current societies.In the prior art, a kind of " high-building self-help device " being arranged, is not to utilize cable wire to hang the control human body to drop to ground from the building outside, and the shortcoming of this technical scheme is: easy to operate, flee from that speed is slow, poor safety performance.China national Department of Intellectual Property discloses a kind of " slow descending device that can escape fast " with publication number CN1298053A, it is the slow lowering pipe that several elasticity necking sections are arranged that constitutes by soft material, be located in the building support column of hollow, form a closed channel that runs through each floor, each floor is provided with inlet, ground sets out mouth, people enter in the pipe and glide by deadweight, because stopping of a plurality of elasticity necking section arranged, make human body fall to obtaining buffering, falling speed reduces, and reaches the purpose that safety is reduced to the ground escape.Yet there is the shortcoming of following two aspects in this slow descending device:

One, security are difficult to ensure.At first, control human body falling speed is by repeatedly stopping realization, its pipeline thickness inequality, and sinking speed is neglected and is neglected slowly soon, and human body easily is hurt by collision.Secondly, the hollow support post is set, has changed the original building structure, the security of building is also influenced.

Its two: the rapid evacuation ability.The many floors of slow lowering pipe use, and reduction of speed is slower, is difficult to realize rapid evacuation crowd's purpose.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of high-speed life-saving channel for high building is provided, and this high-speed life-saving channel for high building can realize that all personnel all fast and safely evacuated in the high building in several minutes.

For achieving the above object, the utility model adopts following technical scheme, comprise: the cylindrical channel main body, described channel body runs through building or each floor of structures, or be attached to outside building or the structures, described channel body by built-in slow lowering pipe, be located at escape entrance that each floor can feed the band door of slow lowering pipe, be located at the escape outlet that ground is connected with slow lowering pipe and form, slow lowering pipe is set up in parallel and is some, and one common peripheral is the multi-head spiral shape around a central axis perpendicular to ground and arranges.

As improvement of the present utility model, the horizontal cross-section of slow lowering pipe is roughly sickleshaped.

As further improvement of the utility model, the lead angle of slow lowering pipe is 50 ° to 60 °.

Further improve as of the present utility model, also comprise a breather pipe that is positioned at channel body inner core part, the breather pipe tube wall is equipped with opening at each floor and is connected with slow lowering pipe.

Further be improved to again, be provided with buffer protection device in the escape exit on ground.

The utility model has following advantage:

One, safe in utilization.Because the utility model adopts some slow lowering pipes that are set up in parallel, and forms some tubulose spiral ramps, the human body gliding speed can be controlled by suitable lead angle is set, and the survivor can not be subjected to collide the ground of arriving safe and sound smoothly.

Two, can realize crowd's rapid evacuation.Slow lowering pipe is set to some simultaneously, every slow lowering pipe all has inlet at each floor, the survivor can enter from channel body any inlet all around nearby, same inlet also can hold the parallel downslide of several people, even accommodate 20,000 people's the 100th floor height buildings, if establish the channel body (in establish 10 surplus a tubulose spiral ramp) of 5 to 6 meters of diameters, but about about 10 minutes all personnel's total evacuations.

Three, passage is difficult for being obstructed.Because channel body adopts the fire prevention anti-ballistic materials to make, accidents such as any floor is blasted, fire all do not influence other floor personnel's evacuation.

Four, implement easily to promote.The high building that has now built up is implemented the utility model, utilizes the repacking of former escape stair space to get final product, and can not influence the original building structure.

Below in conjunction with embodiment the utility model is described in further detail.

Fig. 1 is the channel body partial front elevation view schematic diagram of a kind of embodiment of the utility model.

Fig. 2 is the horizontal cross-section schematic diagram of Fig. 1.

As shown in Figure 1, present embodiment comprises cylindrical channel main body 1, channel body 1 runs through building or each floor of structures, or be attached to outside building or the structures, channel body 1 by built-in slow lowering pipe 2, be located at escape entrance 3 that each floor can feed slow lowering pipe 2, be located at escape that the place, ground is connected with slow lowering pipe 2 and export and form, escape entrance 3 places are provided with oval from closing tiltedly door 4, slow lowering pipe 2 is set up in parallel and is some, and one common peripheral is the multi-head spiral shape around a central axis perpendicular to ground and arranges.As shown in Figure 2, the horizontal cross-section of slow lowering pipe 2 roughly is sickleshaped, closes oblique door 4 certainly and closes automatically after personnel enter, and can prevent that pyrotechnics from entering.Be the safe gliding speed that realizes suiting, it is good that the lead angle of slow lowering pipe is 50 ° to 60 °.

As shown in Figure 2, the utility model also can be set up a central aeration pipe 5, be located at the inner core part of channel body 1, the tube wall of central aeration pipe 5 is equipped with opening at each floor and is connected with slow lowering pipe 2, ground floor can be established air blast, be blown into high wind from central aeration pipe 5 and dispel fire hazard aerosol fog, guarantee personal security.

In addition, the tubulose spiral ramp that the utility model constitutes can be turned round the shape slide plate by the some monolithics of making standard component and assemble.The channel body shell can be a stainless steel case.The horizontal cross-section of slow lowering pipe can be circular, oval or similar deformed shape, and these conversion all fall into protection domain of the present utility model.For increasing security performance, channel body is made by the fire prevention anti-ballistic materials.The cross-sectional diameter that channel body is suitable is 2 to 6 meters, and the suitable quantity that is provided with of slow lowering pipe is 4 to 10.For preventing the collision between the survivor in the slow lowering pipe, also can set up automatic scheduling controlling device, commander survivor evacuates in order.
