AI Technical Summary

Technical Problem

Traditional monorail track beams have a single stress path when bearing loads, resulting in large deformation, which affects the stable operation of the equipment. In addition, the material is not fully utilized and the self-weight is large, making it difficult to meet the comprehensive requirements of large-span retractable roof systems.

Method used

The system adopts a truss-type double-track beam structure, including an upper chord, lower chord, and web system. It utilizes a box-section and inverted T-shaped steel design, combined with angle steel bracing and node connection devices, and adds stiffening ribs and rubber pads to achieve load distribution and vibration reduction. It is equipped with a safety locking device to ensure stable operation.

Benefits of technology

It significantly improves the load-bearing capacity and anti-tilting performance of the track beam, reduces self-weight and construction costs, enhances the economy and sustainability of the large-span retractable roof system, and ensures the stable operation of the equipment.
