Description

A guide rail for variable rails in corridors

technical field

The utility model provides a rail of a guide rail type elevator, in particular to a guide rail used for a variable rail in a corridor.

Background technique

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 the above." Buildings or other public buildings must be equipped with elevators in strict accordance with this standard. However, although most of the floors of residential buildings before 2000 met the above-mentioned standards for installing elevators, due to cost considerations, the building side did not install elevators, which brought inconvenience to residents living in old residential buildings without elevators. Especially for elderly residents who live above the upper floor, traveling up and down has become a major problem. For this reason, some cities have begun to introduce renovation plans for adding elevators to old residential buildings in recent years. However, due to the structural constraints of existing residential buildings, it is generally necessary to install vertical elevators outside the building body. 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 patent with the application number 2016102480036 discloses a stair lift for household stairways. It discloses a convenient wheelchair that is installed in the stairway for hanging and transporting upwards and downwards. In the case of the building, it is inconvenient to pass due to only one guide rail.
