Separated shock-absorption stair

The utility model discloses a separated shock-absorption stair which is composed of stair beams, a stair column, stair plates and a stair rest platform, wherein the stair plates and the stair rest platform are fixed in a frame formed by a frame column and frame beams by virtue of the stair beams and the stair column; a horizontal separation layer is arranged between the stair plates and the stair rest platform or between the stair plates and a floorslab; or a horizontal separation layer or a vertical separation gap is arranged between the stair rest platform and the frame structure. In the separated shock-absorption stair, the horizontal separation or slippage layer is adopted, and the vertical separation gap is arranged, so that an inclined support effect on the building structure under the action of the horizontal load, such as earthquake and the like by the stair, can be eliminated; the adverse effect on the anti-shock capacity of the building structure by the stair is avoided; meanwhile, complexity caused
