Additionally-mounted elevator quarter-floor home-entry stair reconstruction structure and construction method

Abstract

The invention discloses an additionally-mounted elevator quarter-floor home-entry stair reconstruction structure. A plurality of door openings are formed in a wall, close to one side of an original stair, of an old building main body, and each door opening is correspondingly formed between every two adjacent layers of residents; the stair between the every two adjacent layers of residents comprisean upper stair located on the upper part of a half-layer terraced platform and a lower stair located on the lower part of the half-layer terraced platform; the lower ends of the door openings are flush with the half-height positions of the upper stairs; and platform channels extending in the horizontal direction are built between the lower end faces of the door openings and steps at the half-height positions of the upper stairs. A front hall body and an elevator shaft are built at the front end of the old building body, the front hall body is used for connecting the old building body with theelevator shaft, and an elevator hall is arranged in the front hall body; and the bottom surface of the elevator hall is flush with the platform channel. According to the additionally-mounted elevatorquarter-floor home-entry stair reconstruction structure and the construction method, the structure is simple, quarter-floor home entry can be achieved, the reconstruction cost is low, and the construction period is short.

Description

technical field [0001] The invention relates to the technical field of retrofitting an old house with an elevator, in particular to a retrofit structure and construction method of a quarter-floor entry-style staircase with an elevator.
