EARTHQUAKE-ISOLATING SUPPORT Russian patent published in 2015 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: invention refers to the construction industry, in particular to supports of earthquake-resistant structures (buildings). An earthquake-isolating support includes a load-carrying element of a column, which is supported through an upper supporting plate from a metal-rubber support (MRS), and the lower supporting plate of MRS is connected by means of anchor bolts to a foundation; MRS is made of elastic rubber sheets (pads) and metal plates, which are alternately laid on each other, and a central core is made in the middle part. In the foundations there are sockets, into which plate-like (cylindrical) elastic elements are inserted in the form of anchor bolts, the tightening value of which is set with the reliability coefficient γ_f, which is by 1.2-1.5 times more than a horizontal component on the support from the design wind load Pw. The lower supporting plate of MRS is supported from an embedded metal plate of the foundation with holes for the movement of the plate-like elastic elements through a sliding pad.

EFFECT: improvement of the earthquake resistance of a building, simplification of a structure, enlargement of an application field of earthquake protection for buildings with different earthquake intensity.
