MODULAR FOUNDATION FOR SUPPORT Russian patent published in 2019 - IPC E02D27/42 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to modular foundations of concrete for cellular communication support, overhead transmission lines, wind power plants, etc. Modular foundation for support comprises modules made in the form of adjacent reinforced-concrete hollow prisms with square bottom, installed on base symmetrically relative to support prism, inside which there is anchor device for attachment of support, note here that adjacent and support prisms are tightened between them from above and from below by bolt joints, wherein cavities of adjacent prisms are filled with backfill. Relative position of the prisms on the base relative to each other has a plan of the hammer cross, in the center of which there is a support prism with adjacent prisms, which are sides of the cross-hammer, which are attached to four faces of support prism. In the middle of external surfaces of two adjacent faces of each prism vertical concrete ledges are made, and on two other adjoining faces vertical slots are made, which interact with corresponding slots and projections of conjugated prisms. Vertical slots of the prism are limited from below by horizontal mounting partitions, the height of which is equal to twice the thickness of the bottom of the prism. Anchor device of support prism includes hollow steel cylinder having two flanges, upper for connection with mating flange of support and lower, installed on anchor bolts, fixed in bottom of support prism, which cavity is filled with non-shrinking fast-setting steel fiber concrete.

EFFECT: technical result consists in improvement of foundation strength under support, simplification of assembly.
