随着时代变迁,电梯更新迭代的速度也越来越快。根据最新版本的《电梯制造与安装安全规范第1部分:乘客电梯和载货电梯》(GB/T 7588.1—2020),本文研究分析了在不改变大楼原有结构的基础上且曳引式电梯层门地坎间的距离超11米时,依据标准要求分析了井道条件可能出现的特例,提出了三种可行的实施方案,并且对其特点分别进行了描述,有一定的参考意义。

With development of the time,the renewal of elevator is becoming faster and faster,on the latest version of“Safety rules for the construction and installation of lifts—Part 1:passenger and goods passenger lifts”(GB/T 7588.1—2020),new rules were implemented when the distance between consecutive landing door sills exceeds 11 m.This article discusses a special case that might occur under a certain well condition,then proposes 3 designs and describes them separately.
