Secondarily added elevator structure

Abstract

The invention relates to a secondarily added elevator structure, which comprises a multi-layer building, a parallel double stair, an elevator device and a channel, wherein the channel is connected with the elevator device and the multi-layer building; the parallel double stair comprises a first stair segment and a second stair segment for connecting floors and a middle platform for connecting the first stair segment and the second stair segment; the elevator device comprises an elevator shaft and an elevator car moving in the elevator shaft; the channel comprises a cell door hole arranged on a stair outer wall at the side of the middle platform, an elevator waiting car and a landing door; the elevator waiting car and the middle platform are arranged at the same height, the elevator waiting car is arranged between the elevator shaft and the stair outer wall; the landing door is arranged on a first shaft well of the elevator shaft; the elevator shaft is arranged next to the stair outer wall and oppositely to the second stair segment; the unit door hole is arranged oppositely to the first stair segment; the first shaft wall is arranged oppositely to a stair shaft; and an elevator waiting platform is arranged oppositely to the first stair segment. The area of the elevator waiting platform is reduced through changing the installation position of the elevator device, and the space occupied by the secondarily added elevator structure is reduced.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a structure for secondary installation of elevators in existing buildings. Background technique [0002] Due to the limited economic conditions at that time, the residential buildings built in the urban areas of many cities did not install passenger elevators. Now it causes a lot of inconvenience to the daily life of the owners in the residential buildings, especially for the elderly, children, pregnant women, etc., they climb When walking on the stairs, it is easy to step on the air and fall down, which is a certain danger. However, the structure of the old building has been formed, and it is no longer possible to install elevators in the corridors. [0003] At present, the main construction method used for the secondary installation of elevator structures in existing buildings is the outdoor installation method. One of the construction methods is as follows: figure 1 , figure 2 As s...
