METHOD OF DETACHABLE CONNECTION OF FLEXIBLE CONCRETE SLABS AND COLLAPSIBLE PROTECTIVE SHEET Russian patent published in 2017 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: solution refers to construction universal protective concrete coverings. The method of connecting flexible slabs from concrete blocks with lifting eyes characterized by flexibility comprises arranging said slabs side by side, applying an eye of one slab to an eye of an adjacent slab and passing a rigid rod through the matched eyes for connecting the slabs. Then the rod is rotated and the eyes are twisted by said motion, after which, using the same rod, the twisting of the eyes is fixed to prevent its reverse spontaneous untwisting.

EFFECT: possibility of adjusting the size of clearances between the slabs and adjusting the slab position relative to adjacent plates in the sheet, increasing the compactness of the detactable connection assembly of slabs, increasing the stability during operation, exluding the need for fixing the connecting element in the underlying surface, increasing the connection security from external mechanical damaging effects.
