BLOCK FAST-ERECTED EARTHQUAKE-RESISTANT CONSTRUCTION OF KOCHETOV Russian patent published in 2017 - IPC E04C2/08 E04H9/02 

FIELD: construction.

SUBSTANCE: block fast-erecting earthquake resistant design containing a system of blocks and connecting elements connected in a single construction consists of elements made in the form of blocks, one of which is made in the form of a rectangular parallelepiped with grooves made on four faces of a parallelepiped in the plane of its symmetry. The grooves are made with cylindrical openings for the outer diameter of the cylindrical housing of the connecting element, and the other blocks are mated with the first ones and made in the form of a rectangular parallelepiped with studs made on the four faces of the parallelepiped. The studs are made with cylindrical openings for the outer diameter of the cylindrical body of the connecting element. The surfaces of the grooves and studs are equidistant, congruent and equidimensional, and are united into the block prefabricated structure by means of the connecting elements. The coupling element is made of a damper consisting of an elastic cylindrical shell with flat hard stops attached to the ends of the thread by means of a thread and the inner cavity is filled with a set of at least two damping disks fixed to an elastic axis coaxially disposed with a cylindrical shell and between damping disks, there is at least one cylindrical coil spring. The cavity of the cylindrical shell is filled with a vibration damping material, for example polyurethane or construction foam, or the connecting element for the blocks of an earthquake-proof structure consists of an elastic cylindrical body with flat hard stops fixed at its ends. Hollow cylindrical body filled with a damping material and the housing is made of two flanges, of opposite and coaxial cylindrical threaded sleeves rigidly secured to their end portion flat rigid stops, which are made elements for a threaded joint bushing in a single cylindrical body, and is made of elastic material example of a resilient spring steel, the cavity of which is filled with damping material, such as vibration-damping mastic type "VD-17", or within the cylindrical body of the connecting element coaxially and coaxially there is a cylindrical tubular damping element consisting of a cylindrical shell with bases made of a rigid resilient vibration damping material, for example of the Agat type, the inner cavity of which is filled with a damping material, for example sand, or a vibration dampening mastic of the "VD-17" type. The internal cavity of the connecting element between the cylindrical body and the outer surface of the cylindrical shell of the cylindrical tubular damping element is filled with a less rigid vibration damping material, for example polyurethane.

EFFECT: increased seismic resistance.
