Method for improving high-rise building safe evacuation scissors staircase and structure thereof

The invention relates to a method for improving a high-rise building safe evacuation scissors staircase and a structure thereof. The invention is characterized in that one section of any two-section straight run staircases of existing scissors staircases is selected, internally folded and connected to a corresponding floor, and the folding positions of the two staircases are all designed to be rest platforms. The invention reduces the stair well face widths of the staggered staircases of the existing high-rise buildings, completely uses space heights among floors, effectively reduces the spacearea of public stair wells, reduces the face width of the stair wells without reducing the bearing capacity of the floor, reduces unnecessarily wasted land area, and reduces the construction cost ofthe high-rise building safe evacuation scissors staircases. For the invention, distance between two end openings of each floor is shorter, when fire incidents occur, persons in the building can arriveat the other end opening f
