Problems solved by technology

[0003] However, if the floor is high or emergency evacuation is required, it takes a long time to go up and down ordinary stairs, and when most people choose stairs to escape, congestion will occur, sometimes it is too late to evacuate or escape from the fire.

Embodiment approach 1

[0019] refer to Figure 1 ~ Figure 3 , a combined staircase for quick escape, comprising an ordinary staircase 10 and an escape spiral slide 20 . The escape spiral slide 20 is located between the upper and lower sections of the ordinary staircase 10 , and an annular gap 101 is provided between the escape spiral slide 20 and the ordinary staircase 10 . The helix angle of the escape spiral slide 20 on each floor is equal to the inclination angle of the ordinary staircase 10 .

[0020] Ordinary staircase 10 is made up of upper stair section 11, lower stair section 12, front platform 13, rear platform 14 and railing 15. The inner side of the upper stair section 11 is provided with a circular arc R1 with a radius of D2 / 2 along the vertical direction. In order to compensate the strength of the opening, the lower side of the bottom plate of the upper stair section protrudes outward to form a fan-shaped ring 111 . The inner side of the lower stair section 12 is provided with a circu...

Abstract

The invention discloses a quick escape combined stairway. The quick escape combined stairway comprises a common stairway and a helical escape slide. The helical escape slide is arranged between an upper stair section and a lower stair section of the common stairway. The helical escape slide is in clearance fit with the common stairway. The clearance is annular. The helix angle of each layer of thehelical escape slide is equal to the inclination angle of the common stairway. According to the quick escape combined stairway., the original gradient of the common stairway is maintained; the helical escape slide is arranged between the upper stair section and the lower stair section of the common stairway, and the helical escape slide is in clearance fit with the common stairway; in this way, no matter what disaster happens, people can get into the helical escape slide from the common stairway to quickly escape at any time; when escaping through the helical escape slide, the sliding speed of people on each layer is only about 4 s, the speed is high, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a combination staircase for rapid escape. Background technique [0002] Stairs are components used as vertical traffic between floors in buildings, and are mainly used for traffic connections between floors and when the height difference is large. Although elevators are used as the main vertical means of transportation in high-rise buildings, stairs are still reserved for escape in case of fire. People are used to escaping from the stairs because they are used to the inclination of the stairs, and they can go up and down the stairs proficiently even when there is a power failure at night. [0003] However, if the floors are higher or emergency evacuation is required, it takes a long time to go up and down the ordinary stairs, and when most people choose the stairs to escape, crowding will occur and sometimes it is too late to evacuate or escape from the scene of th...
