Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge equipment technology, and more specifically, it relates to a bridge tension-compression bearing. Background Technology
[0002] Tension-compression bearings, also known as negative reaction bearings, are bearings that can withstand both positive and negative reactions simultaneously. They are often installed on bridge supports to cope with bridge vibrations.
[0003] Common tension-compression bearings achieve lateral movement through sliding between internal components to adapt to changes in pressure. However, when subjected to pressure, these bearings inevitably experience impacts between components before movement, altering the direction of force transmission. Steel-to-steel contact can damage components. Furthermore, there is a limit to the lateral movement of the equipment. If the transmitted force is large, the impact force on the moving structure is significant, potentially causing contact with edge structures and impacting the equipment's lifespan. Additionally, common tension-compression structures only provide lateral movement to cope with lateral pressure, while longitudinal stability relies on the bridge's support columns themselves. Although there is no concern about instability, long-term use can still cause longitudinal tension and compression impacts to act on the bearing's interior, affecting the fit of internal components, causing damage, and ultimately impacting the equipment's lifespan.
