Variable rigidity energy consumption type joint for connecting tubular pile head with bearing platform
The invention relates to a connection joint in a building structure, in particular to a variable rigidity energy consumption type joint for connecting a tubular pile head with a bearing platform. The variable rigidity energy consumption type joint comprises two disc-shaped spring structures of the same structure, a flexible outer packaging shell, a concrete expansion head, multiple bearing platform connecting anchor bolts and multiple pile head connecting anchor bolts. The disc-shaped spring structures are arranged between the bearing platform and the tubular pile head, the flexible outer packaging shell covers the two disc-shaped spring structures, and the concrete expansion head is poured to the tubular pile head. When the joint receives large external bending moment or shearing force or axial force, the spring structures provide certain resistance and can generate proper elastic corners or elastic deformation, seismic energy can be consumed, the bearing platform connecting anchor bolts and the pile head connecting anchor bolts are matched with the two disc-shaped spring structures, compression-resistant, tensile, bending-resistant and shearing-resistant bearing force needed when the static load or the movable load effect is achieved can be provided, and when the external effect disappears, the joint can be elastically reset and can be used without being restored.
