FIELD: construction, particularly to strengthen load-bearing members of reinforced concrete structures damaged by fire, explosion or accident. ^ SUBSTANCE: anchoring device comprises thrust member for prestressing reinforcement struts made as steel pressure case. The steel pressure case includes composite clips with thrust ribs at ends thereof provided with tightening bolts. ^ EFFECT: provision of high-quality joint action of anchoring device members and reinforced concrete member to be strengthened and, as a result, increased load-bearing ability of anchoring device and resistance to shearing stress action due to 2-3-fold increase of static rest friction coefficient between pressing casing and concrete of member to be reinforced. ^ 23 cl, 8 dwg |
