Description

Corridor elevator

technical field

The invention relates to the technical field of existing building reconstruction, in particular to a stairway elevator installed in the stairwell of the existing building.

Background technique

Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors.

The national standard "Code for Residential Design" that came into effect on June 1, 1999 stipulates that "elevators must be installed for residences with seven floors or above or the height of the top floor of the residence from the outdoor design ground exceeds 16m." After the promulgation of this standard Residential buildings or other public buildings must be equipped with elevators in strict accordance with this standard. However, although the floors of most residential buildings before 1999 met the above-mentioned standards for installing elevators, due to cost considerations, the building side did not install elevators. It is inconvenient for residents in old residential buildings without elevators to travel, especially for elderly residents living on the second floor or above. Traveling up and down has become a major problem. The renovation plan of adding elevators to residential buildings, however, due to the structural constraints of existing residential buildings, generally requires the installation of vertical lifts on the outside of the building. The installation and maintenance costs are high, and it will also affect the lighting of low-rise residents.

In order to solve the problem of high cost of installing vertical elevators in existing residential buildings, there are many corridor seats that can be installed in the corridors on the market. The corridor seats are a kind of elevator that runs on the side of the stairs. The main function is to help people with limited mobility (the disabled and the elderly) go up and down the stairs at home. The structure of the stair lift is generally composed of three parts: the track, the driving device, and the seat. There are two types of structures: continuous and segmented. Although this type of elevator can transport people or However, the segmented structure is inconvenient to use, and the continuous structure takes up a lot of space and has poor security. It has not fundamentally solved the problem of travel difficulties for elderly residents above the fifth floor.
