AI Technical Summary
Existing Z-type purlins are prone to deformation or damage when subjected to heavy loads. Furthermore, existing reinforcement devices do not fit the purlins well enough, have poor specification compatibility, and cannot effectively disperse stress, resulting in safety hazards and high construction costs.
A novel Z-shaped purlin section reinforcement device is designed, comprising a main beam, Z-shaped purlins, reinforcement components, and fasteners. The cold-bent metal reinforcement components are tightly fitted to the purlins, and the fasteners achieve a firm connection. It is suitable for purlins of different specifications, and can be quickly installed and distribute load stress.
It significantly improves the bending stiffness and overall stability of purlins, reduces construction difficulty and cost, adapts to the needs of purlins with different spans and specifications, ensures uniform stress transmission, avoids secondary stress concentration, and enhances the safety and applicability of roof structures.
