[0002] Flexible keel connections are a widely used connecting material in the construction industry, primarily used to connect the edge keels in building structures to provide greater stability and support. This flexible connection design allows for a degree of flexibility and buffer space, enabling it to more effectively disperse and absorb impact forces when dealing with changes in the stress on the building structure. However, existing flexible keel connection structures have poor vibration damping and noise reduction performance, and noise is easily generated at the keel connection points.
