AI Technical Summary

Technical Problem

The existing external steel structure staircase requires adjustment of the angle of each fixing block according to the installation tilt angle during construction, resulting in poor applicability and inability to meet the needs of staircases of different heights and spans.

Method used

The support components include a first inclined beam, a second inclined beam, and a telescopic rod. By adjusting the length of the telescopic rod and the tilt angle of the connecting rod, the pedal is kept level. Combined with the limiting components and the slider structure, the pedal can be easily installed and removed.

Benefits of technology

It improves the usability and comfort of the stairs, ensures that the treads remain level during use, and enhances the efficiency and safety of disassembly and assembly.
