Unlike traditional conveyor corridor that use main steel trusses and profiled steel sheets as enclosure structures, the side panels of prefabricated modular conveyor corridors employ corrugated plates with vertical stiffeners as the primary loadbearing structure. However, there are no specific codes for their mechanical analysis and structural design methods. To address this, the design process and methodology for the side panel structure of prefabricated modular conveyor corridors is detailed. The proposed dimensions for a single side panel are a height of 3000~3800mm and a length of 12000mm. The corrugated plates have a wave height of 50~100mm and a wave pitch of 300 mm. The upper part of the side panel has a curvature radius of 1100 ~1500mm, with a corresponding central angle of 27°~45°. The research results comprehensively consider factors such as load-bearing capacity, stability, and manufacturing difficulty, ensuring rational structural design and dimensions for each part of the side panel to meet the requirements of prefabricated modular trestles.
