AI Technical Summary
Traditional snow load-assisted stabilization devices cannot provide buffering when the snow load exceeds the bearing capacity of the steel structure, leading to the collapse of the steel structure and resulting in poor safety.
A device comprising a first fixed half-ring and a second fixed half-ring is designed. Through a stabilizing base assembly and a stabilizing drive assembly, when the snow load is too high, the second fixed half-ring moves and pulls the first fixed half-ring tightly against it by a winding cloth, thereby enhancing the support strength at the connection.
When the snow load is too high, the dynamic adjustment of the device enhances the support strength at the joints of the hyperbolic steel structure, thereby improving safety.
