CONNECTING ELEMENT FOR MODULAR STRUCTURE Russian patent published in 2018 - IPC E04C2/04 

FIELD: construction.

SUBSTANCE: invention relates to the technology of erecting earthquake-resistant structures. Connecting element for the modular structure consists of an elastic cylindrical body with mounting discs fixed to its ends, and the cavity of the cylindrical body is filled with damping material, body is made of two flanged, oppositely disposed and coaxial cylindrical threaded bushes with mounting discs rigidly attached to their end part, on discs there are elements for threading the bushes into a single cylindrical body made of an elastic material, for example, from an elastic spring steel, the cavity of which is filled with a damping material, for example, a vibration damping mastic of the "VD-17" type, connecting element for the units of an earthquake-resistant structure is made damping, consisting of an elastic cylindrical shell, to the ends of which the flat mounting disks are connected by threads, and the inner cavity is filled with a set of at least two damping disks fixed to an elastic axis coaxially disposed with the cylindrical shell, and between the damping disks there is at least one cylindrical helical spring, and the inner central cavity of the cylindrical shell is filled with vibration damping material, for example, a vibration damping mastic of the "VD-17" type. At least three elastic rods of less rigidity than that of the elastic core are placed inside the elastic cylindrical body coaxially to the elastic core, they are fixed in the damping disks in such a way that their external surfaces touch the inner surfaces of the helical coil springs.

EFFECT: increased effectiveness of seismic resistance due to the spatial protection from seismic waves by introducing each unit into a single earthquake-resistant structure by means of connecting damping elements.
