Two-way door-opening machine-room-free elevator structure and arrangement method thereof

The invention relates to the related technical field of machine-room-free elevator structures and civil engineering arrangement, and discloses a two-way door-opening machine-room-free elevator structure and an arrangement method thereof, and the two-way door-opening machine-room-free elevator structure comprises a car bottom platform which is arranged in an elevator shaft and vertically ascends and descends. Lift car guide rails are arranged at the diagonal positions of a shaft, two lift car doors entering and exiting in the 90-degree direction preferentially adopt a door opening mode of laterally opening two doors, the lift car guide rails are arranged on geometric diagonals of a lift car platform in an arrangement method that diagonal vertexes are symmetrically distributed, and meanwhile the working top faces of the lift car guide rails are arranged at the diagonal vertexes of the lift car platform. A small amount of corner wiping treatment is conducted on the opposite angles of the car bottom platform wher
