QUAKEPROOF SUPPORT OF BUILDING Russian patent published in 2012 - IPC E02D27/34 E04H9/02 

FIELD: construction.

SUBSTANCE: quakeproof support of a building comprises a pile, support links and movable links, damping elements, fixing elements. The pile is made as formed, telescopic and hollow from inside, links and damping elements arranged inside the pile may move relative to each other and relative to the pile body in vertical and horizontal planes at the invariable vertical and horizontal position of the central support link - a plunger, which is rigidly connected to the building foundation, resting against quakeproof supports that are arranged along the foundation perimetre and under the building foundation bottom. In the formed telescopic pile at its end part there are two cylindrical seats of different diametre and different depth. At the bottom of the upper seat there is a polymer antifriction coating of circular shape in plan, on top of which there is a set of horizontally damping elements made of pressed wire spirals that are tightly pressed to each other in circumferential, radial and vertical directions, the external edge of which is provided along the circumference, the diametre of which is equal to the diametre of the upper seat, and the inner edge of which is also made along the circumference. Inside this set of horizontally damping elements there is a support movable sleeve tightly installed and resting against the polymer antifriction coating. At the bottom of the support sleeve there is a through cylindrical hole, inside the support sleeve there is a set of vertically damping elements made of pressed wire spirals that are tightly pressed to each other in circumferential, radial and vertical directions and tightly pressed to the bottom of the support sleeve, the external edge of which is provided along the circumference, the diametre of which is equal to the inner diametre of the sleeve, and the inner edge of which is made along the circumference. Inside this set there is a support plunger tightly installed, being rigidly connected to the building foundation, in the upper end part of the support plunger there is a dead seat, where an orifice is installed, being rigidly connected to the support elements of the building foundation. On the upper end part of the support sleeve there is a sealing sleeve tightly installed with seals, creating a cavity between surfaces of the support plunger and vertically damping elements. At the end surface of the telescopic pile there is a limiting circular orifice, and at the external cylindrical surface of the telescopic pile there are fixing ribs of channel-like shape rigidly installed with an even pitch along the circumference.

EFFECT: higher efficiency of the device by increasing its damping properties in the vertical and horizontal planes, increased strength and durability.
