Background
The transformation of old urban districts is a significant civil engineering and development project, and has important significance for meeting the demand of people on good life. With the increasing aging of cities, old houses have become 'necessary' to install elevators, and governments have given a lot of policies.
However, since the existing building 100 is mostly two-run stairs 200, as shown in fig. 1 and 2, the elevator can only be stopped at the landing 300 (half-floor position) of the stairs. Even if the elevator is additionally arranged, the elevator can be entered only by running a half floor, so that the elevator is still difficult to use by the elderly and residents with inconvenient legs and feet, and the problem of no obstacle can not be really solved.
If Chinese patent No. 201721402832.1 also discloses a building structure of a multi-storey residential building after being additionally provided with elevators, the building structure comprises an old building and an external elevator system, wherein the external elevator system is arranged corresponding to each storey of the old building, the external elevator system at each storey comprises a vertical elevator, a connecting corridor, an elevator storey entrance and exit, an entrance channel and a fire fighting channel, the connecting corridor is connected with the vertical elevator and the elevator storey entrance and exit, and the elevator storey entrance and exit is formed by modifying the wall body of the old building; the entrance passage is communicated with the door and the elevator floor entrance; the old building comprises an upper-half-floor stair, a lower-half-floor stair and a connecting part of the upper-half-floor stair and the lower-half-floor stair, wherein the connecting part and an entrance of the elevator floor form a height difference, and a fire fighting channel is arranged to communicate the connecting part and the entrance of the elevator floor. The structure does not change the internal structure of the building, is connected with the old building from the outside, realizes the ramp trip and entrance of a resident, but does not realize the barrier trip and entrance of the resident, and is not beneficial to the wheelchair passing.
For example, chinese patent No. 201920955288.6 discloses a building structure after an elevator is installed in a multi-storey residential building for old building reconstruction, which includes an old building and an external elevator system, the external elevator system is installed corresponding to each storey of the old building, the external elevator system of each storey includes a vertical elevator, an elevator entrance, a gentle slope platform and an additional installation platform, the elevator entrance is reconstructed from the wall of the old building; the upper end of the gentle slope platform is communicated with the door, and the lower end of the gentle slope platform is connected with the additional platform; the elevator is arranged on the outer side of a half-layer platform of a staircase of an old house, the height of the elevator installation platform is 80-100cm higher than that of the half-layer platform of the staircase, and the lower half-step ladder is provided with an extension step ladder to communicate with the half-layer platform and the installation platform. This building structure realizes installing the elevator additional after, and half layer slope is gone into the family from top to bottom, makes things convenient for old man, child and sits handicapped people such as wheelchair and go up and down stairs.
The schemes of adding the elevator to the buildings related to the two patents are that the original two-way stairs are reserved, so that the reformed building has the defects of insufficient clear height of the stairs, a rest platform in the middle of the stairs and a waiting platform of the elevator are combined into a whole, and the phenomena of extrusion and treading are easy to occur in emergency situations, so that the problems of being not beneficial to evacuation and the like are solved; some residents go out and enter the household on a slope, but do not go out and enter the household without obstacles, and are not beneficial to wheelchair passing.
