Abstract

Stairs are very important in dealing with various complex Spaces in construction projects. However, the application space of stairs is limited, and it is necessary to connect two separate parts in sufficient space. In order to solve this problem, a telescopic ladder based on scissor unit and expansion is proposed. In this study, the retractable and expandable basic unit and optimization and ordinary retractable stairs cannot transport large and heavy objects or over the service life and structural instability and other problems were improved and optimized.
