ANTI-SEISMIC CONNECTION JOINT HAVING A SLOTTED HOLE

摘要

A mechanical anti-seismic connection joint (100) comprises a female element (10) and a male element (20), fixable to the respective structural components (110,120). The female (10) and male elements (20) are joined by a pin (30) to form a connection hinge (40) between the structural components (110,120). The pin (30) is inserted in at least one slotted hole (33) provided on a support (14) of the female element (10). The mechanical joint (100) is arranged such that the hinge (40) is provided with a damping element constituted by the pin (30) inserted in the slotted hole (33) and translatable along a trajectory (T) defined controlled by the shape of the slotted hole (33). Advantageously, the mechanical joint (100) exploits the forces generated by the earthquake to reactivate the characteristics of stability already present in the building, but momentarily made unavailable by sussultatory type shocks.
