Replaceable connecting beam with double-security mechanism

Abstract

The invention discloses a replaceable connecting beam with a double-security mechanism. The replaceable connecting beam comprises a replaceable member and concrete connecting beams at the two ends ofthe replaceable member, the replaceable member comprises a metal damper, a limiting anti-buckling restrained supporting device, a replaceable member connecting plate and a metal damper connecting plate. According to the replaceable connecting beam with a double-security mechanism, under the action of a large earthquake and a principal earthquake, the metal damper centralizes plastic damage, underthe action of a super-large earthquake or a large aftershock, when the metal damper fails and there is not enough time to replace the metal damper, therefore, the plastic damage is centralized into the replaceable member all the time, and other parts of the structure can be protected against unrepairable damage.

AI Technical Summary

Benefits of technology

This new design improves safety measures for structures made up of connectors between different parts like pipes during an accident caused by seismicity events such as quaking floods. It also includes features like separating and replacing worn out portions of these connections instead of having them all together at once, reducing maintenance costs while still maintaining their effectiveness against severe impacts. Overall, this technology helps prevent damage over longer periods of use compared to previous designs.

Problems solved by technology

This patented technical problem addressed in this patents relates to controllably restoring destructive forces that may occur when an external load tries to break down or reconstruct constructions used for protection purposes like houses or bridges. Current methods involve adding new materials to strengthen existing construction elements before they fail catastrophically, resulting in increased costs associated with repairs and downtime while also increasing safety hazards related issues.
