FOUNDATION ON VIBROPROTECTIVE ELEMENTS Russian patent published in 2010 - IPC E02D27/44 

FIELD: construction.

SUBSTANCE: invention is related to means of protection against hazardous effect of vibration and may be used in construction, in particular in arrangement of vibration-insulated foundations for machines and equipment with dynamic loads. Foundation on vibroprotective elements comprises bath, foundation unit arranged in it with clearance versus walls and bottom and hingedly joined to vibration isolators installed in bath bottom. Vibration isolators are joined to foundation unit by means of hinged lever, which connects foundation unit to support element of vibration isolator, which comprises elastic element, body and pendulum suspension. Body is arranged in the form of box with lower base and upper plate with hole for threaded pin of pendulum suspension, which are connected to each other by three side ribs, with creation of window for accommodation of support lever, on which vibration-insulated object is arranged. Elastic element is arranged in the form of three serially connected elements: elastic ones and elastic-damping element arranged in between. Elastic elements with one of their bases are installed in bushes, which are fixed accordingly on upper plate of body and cover, and rest against washers with their other bases, and washers are joined with elastic-damping element. Pendulum suspension is arranged in the form of threaded pin, which is connected by one end to support lever for fixation of vibration-insulated object, and by other end - to nut and thrust washer, which is joined to cover attached to elastic element. Elastic-damping element is arranged in the form of steel-wire weaving or metal thread waste.

EFFECT: increased efficiency of spatial vibration insulation and simplified design.
