An elevator for retrofitting in an existing building

Abstract

An elevator for installation in an existing building, comprising a transmission mechanism installed under the stair section and fixedly connected with the stair section, an elevator car capable of going up and down under the action of the transmission mechanism, and a The reversing sliding platform mechanism under the connecting platform between adjacent stair sections and fixedly connected with the connecting platform, the reversing sliding platform mechanism is used for reversing the elevator car so that the elevator car can be transported from the bottom of the previous stair The mechanism reverses to the transfer mechanism below the next flight of stairs. On the basis of basically not changing the structure of the existing building, it can be installed on the back of the original walking staircase to realize the transformation of the way of going up and down the existing building. The cost is low, the installation is convenient, and it can adapt to buildings with various design styles of walking stairs . Great promotion and application value.

Description

technical field [0001] The invention belongs to the technical field of existing building renovation, and in particular relates to an elevator for retrofitting an existing building. Background technique [0002] In the early construction of residential buildings (mainly 5-10 floors), due to the constraints of the conditions at that time, they were basically buildings without elevators. According to the service life of residential buildings, most of these early buildings still have several ten years of use. At present, with the improvement of material living standards, people's requirements for a better and happy life are also getting higher and higher. It has become an urgent problem to be solved now to install elevators in these early buildings to meet the needs of residents, especially elderly residents, etc., and those with disabilities. [0003] Most of the elevators in the prior art have complex structures and large volumes, and require special shafts and machine rooms...

AI Technical Summary

Problems solved by technology

This kind of external elevator not only still needs to modify the existing building (need to dig a doorway for the residents on the outer wall corresponding to the rest platform), but also the residents still need to walk a section of walking stairs in the process of using the elevator. To reach the elevator or the door of the residents, in addition, such a solution needs to occupy a large area outside the building, and it is easy to affect the lighting of some residents; moreover, most of the elevator cars of this type of elevator are made of transparent materials, and passengers can move freely when the elevator is going up and down. The windows of some residents can be seen from the car, which will affect the privacy of some residents, and the privacy is relatively poor

In addition, the cost of this kind of external elevator is relatively high.
