The invention discloses a construction method of a trackless self-lifting self-locking type double-layer cage frame of a vertical hoistway. The construction method comprises the steps of reserving a safety shaft fixing hole in a wall surface, manufacturing a lower-layer cage frame, manufacturing an upper sleeve frame, installing a safety self-locking shaft, installing a crawling ladder and installing lifting equipment. On the basis of engineering practice, the advantages and disadvantages of traditional steel pipe fastener type scaffolds and triangular hoisting scaffolds of an elevator shaft are analyzed, the construction technology of the trackless self-lifting self-locking type double-layer cage frame is provided, vertical hoistway scaffolds are tooled, the progress is fast, materials are saved, and the safety performance is improved.

    本发明公开了一种竖向井道无轨自升降自锁式双层笼架施工方法,包括如下步骤:墙面预留安全轴固定洞口→下层笼架的制作→上部套架的制作→安全自锁轴安装→爬梯的安装→升降设备的安装。本发明以工程实践为基础,分析了电梯井传统的钢管扣件式脚手架、三角形吊装升脚手架的利弊,提出了无轨自升降自锁式双层笼架的施工技术,使竖向井道脚手架工具化、进度快、材料省、安全性能提高。
