FLEXIBLE CONCRETE MAT WITH FIXATION OF BEND (VERSIONS) Russian patent published in 2014 - IPC E02B3/12 E02D17/20 

FIELD: construction.

SUBSTANCE: flexible concrete mat comprises concrete blocks connected to each other by rows and in rows with a gap by an embedded rope. In concrete blocks of the flexible mat according to the first version there are two partially embedded metal elements, made as capable of creation of a welded joint with an additional common stiff metal element for fixation of their mutual position. Embedded metal elements are connected with concrete blocks so that they are capable to withstand at least the double weight of the concrete block. The partially embedded metal element has thickness of more than 1.5 mm and length and/or width of at least 10 mm in its non-embedded part. The second version of the flexible concrete mat comprises at least two metal plates, partially embedded in adjacent concrete units. The plates have thickness from 1.5 mm to 5 mm, length and width of the non-embedded part is at least 10 mm. Mutual position of concrete blocks is fixed by means of at least one straight or bent stiff metal element, welded to embedded plates.

EFFECT: excluded arbitrary shifts of concrete blocks relative to each other after placement of a flexible concrete mat on a protected surface.
