Abstract: A collapsible spiral-tube escape way includes a plurality of spiral-tube units supported on tube-supporting frames. In a first embodiment of the escape way, the tube-supporting frames in a standby position are elevated and collapsed to sit on a crane mounted on a roof of a building. In an emergency, the whole escape way is vertically lowered to locate in front of and connect to exits of the building, so that users may easily enter into the spiral-tube units via the exits at different floors and slide all the way down to the ground. In a second embodiment, the tube-supporting frames in the standby position are separately pivotally lifted to flatly attach to the exterior wall of the building outside the exits. In an emergency, users need only to open the exits and the tube-supporting frames automatically tilt down to a horizontal position to pull open the spiral-tube units for use.
