AI Technical Summary

Technical Problem

In existing steel structure projects, pre-welded fixed ladders cannot be reused, and steel wire rope fixed ladders are complicated to install and dismantle, pose safety hazards, and do not conform to the concept of green construction, resulting in high costs.

Method used

The modular steel structure assembled vertical climbing ladder includes standard ladder sections, expansion ladder sections, and hook-up components. It can be quickly installed and dismantled through the combination of angle steel ladder beams and rungs, adapts to different steel column lengths, and ensures safety through hook-type connections.

Benefits of technology

It enables rapid installation and dismantling, improves construction efficiency, reduces costs, ensures safety, avoids thermal impact on the parent material, adapts to different steel column lengths, and conforms to the concept of green construction.
