Abstract

An evacuation chute relates to a facility used for escaping from a storied building and comprises inlets and an outlet. The utility model is characterized in that the chute is a spiral chute, wherein the outlet is arranged at the bottom layer and the inlets are arranged at the top layer and the middle position. The cross section of the chute is a rectangle, and the cross section of the chute is also an arc. The included angle between the bottom layer of the chute and the ground plane is less than 75 DEG. The utility model can be widely used for fire prevention, gas prevention and explosion prevention in a high-rise building.

Description

A kind of escape slideway

Technical field

The utility model relates to a kind of facility that is used for the building constructions escape, the particularly slideway of escaping about building constructions.

Background technology

The escape outlet of existing building, or extra exit, emergency exit are the stair form, though it is a designated lane, but deficiency is: 1, every layer all has door, and do not open crucial moment, on fire as building, the intensity of a fire is bigger, and dense smoke is very big, and personnel may can not find the emergency exit in flurried; Even 2 find the emergency exit, its outlet communicates with stair and each layer, may cause cigarette, fire to arrive this place, and personnel may be hurt in downstairs; 3, it is slow that personnel utilize emergency exit escape speed.

The utility model content

Technical problem to be solved in the utility model is the escape slideway that a kind of safety of escaping of proposition, escape speed are sought import soon, easily.Can not utilize any electric energy, pulley rope etc. are safest means of escape.

Technical scheme provided by the utility model is: it comprises import, outlet, it is characterized in that: described slideway is the scroll slideway, and wherein, outlet is at bottom, and import is located at top layer and middle part.

The cross section of described slideway is a rectangle.

The cross section of described slideway also is an arc.

The bottom of described slideway and the angle of ground level are less than 75 °.

The utility model has following advantage: 1) because the escape slideway is a scroll, its escape speed is fast; 2) can make special-purpose escape slideway with fire-retardant heat-insulation material, therefore, have the characteristics of escape safety; 3) the utility model take up room little, can be in building many places install, seek import easily, speed is fast, insurance, safety.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the schematic diagram of Fig. 1 cross section embodiment one;

Fig. 3 is the schematic diagram of Fig. 1 cross section embodiment two.

Figure number explanation: 1 top layer, 2 bottoms, 3 slideways.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

As shown in Figure 1, described escape slideway 3 is a scroll, and outlet is at bottom 2, and import is located at top layer 1 and middle part.

As shown in Figure 2, the utility model embodiment one is that the cross section of escape slideway 3 is a rectangle.

As shown in Figure 3, the utility model embodiment two is that the cross section of escape slideway 3 is an arc.

In specific implementation process:

(1) top layer 1 import, bottom 2 escape outlet, if any safety measure preferably, the escape import also can be installed in the centre.

(2) top layer 1 import, slideway 3 can design single track or two pass or many slideways, make the survivor not produce probably high sense, and dare from then on to escape.

(3) its slideway 3 should be according to its material, and design grade makes sliding speed suitable, and the escape personnel can be stood, and can not come to harm in slideway, and the outlet gradient is fit to; If the gradient is bigger, certain safety measure can be taked in its exit, and promptly slideway 3 bottoms 2 are less than 75 degree with the angle on ground, make the escape personnel being slipped to the unlikely greater impact power that is subjected in exit, at utmost guarantee personal security.

Escape slideway 3 itself is firm, and fire prevention, insulation do not produce fire, cigarette and high temperataure phenomena because of on fire making in the slideway.

What of escape slideway should be according to building constructions importance, its functional characteristics, and personnel live what, how much consider to be provided with.

The slideway material of main part can adopt the armored concrete agent structure, and there is smooth sturdy material on the top layer as floor tile, firm long life material such as marble, engineering plastics etc.

The utility model can be widely used in fire prevention, the gas defence, explosion-proof of skyscraper.
