More specifically, the insulator includes a lower unit composed of a horizontal circular friction plate having a truncated cone at its center, and an upper unit composed of a circular cap with a downward-turned concavity covering the lower unit such that the bottom of the concavity rests on the top of the truncated cone and lower edges on the friction plate of the lower unit. An annular space is provided between the lateral wall of the upper unit and the lateral walls of the truncated cone of the lower unit making relative lateral movement possible. At least one collar, also made from a rot-resistant material and having high shock-absorbing features, is positioned in the annular space located between the two units. The insulator is designed for insertion between the ground and the buildings, and is constructed with a view to making the building capable of withstanding the most violent seismic shocks. |
