Description

Technical Field

[0001] The present invention relates to the technical field of old residential quarters reconstruction, and in particular to a construction method for installing elevators in residential buildings in old residential quarters. Background Art

[0002] Most old buildings were built in the 1960s and 1970s. They are characterized by a large number of floors and are not equipped with elevators. As time goes by, the residents of old buildings gradually enter old age and have difficulty going up and down stairs and inconvenience in travel. Taking the elevator up and down the stairs has become a strong desire and urgent need for residents of old buildings. In the construction of installing elevators in multi-story old buildings, common entry methods are direct entry on the flat floor and entry on the upper and lower half floors. In the first entry method, a door needs to be opened in the resident's home when installing the elevator, which damages the decoration of the original house. In the second method, the flat floor location of the elevator is at the original floor conversion platform (also known as the rest platform). Users who take the elevator need to go up and down half a flight of stairs before entering the house. This installation method still does not solve the problem of barrier-free travel for the elderly, the weak, the sick and the disabled and other people in urgent need;

[0003] To this end, this patent proposes a construction method for renovating and installing elevators in old residential buildings to solve the above problems. Summary of the invention

[0026] (III) Beneficial effects

[0027] The present invention provides a construction method for installing elevators in old residential buildings, which has the following beneficial effects:

[0028] 1. The present invention installs the elevator inside the exterior wall of the building through on-site survey, and uses multiple steel pipe piles, foundation steel bars and embedded bars to reinforce the elevator shaft. The construction operation is carried out without affecting the passage of residents in old residential areas. At the same time, the entire elevator installation structure will not change the original internal structure of the corridor, so as not to affect the stability of the residential corridor, so as to avoid subsequent safety hazards. At the same time, after the elevator is installed, considering that the occupancy rate of the elderly in the old residential areas is relatively high, a slope structure is set at the outer end of the unit door, which can be beneficial to the barrier-free passage of the elderly's wheelchairs and improve the use effect of the entire elevator.
