Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a self-resetting rotating beam hinge based on a disc spring. Background Technology

[0002] In the field of building engineering, the stability, safety, and resilience of building structures after being subjected to external forces have always been important research topics. Traditional reinforced concrete structures often experience significant deformation and damage after being subjected to external forces such as earthquakes and strong winds, forming plastic hinges at beam ends and other locations. These hinges are difficult to restore to their initial state on their own, which not only affects the normal use of the building but may also pose serious safety hazards. Therefore, the need to improve the seismic performance and durability of building structures is increasingly urgent. With the continuous development of prefabricated building structures, artificial plastic hinges at beam ends have received widespread attention in recent years due to their reliable connections and ability to quickly repair themselves after earthquakes, reducing structural damage. However, most artificial plastic hinges currently lack self-resetting capabilities and will also be damaged under small to medium-sized earthquakes, requiring frequent structural repairs. Furthermore, prefabricated structures urgently need reliable connection methods to ensure structural integrity. Self-resetting artificial plastic hinges, through their multi-stage failure modes, can achieve adaptive hysteresis behavior under different earthquake magnitudes. Therefore, artificial plastic hinges with self-resetting functions are more suitable for prefabricated buildings. However, existing rotary hinges are insufficient in terms of self-resetting function, and cannot effectively cope with frequent external impacts and deformations, thus limiting the reliability and stability of building structures in complex environments. Therefore, developing a self-resetting rotary hinge with excellent reset capability to improve the connection performance and assembly efficiency of building structures has become an urgent problem to be solved in the field of building engineering.
