FIELD: construction, particularly working measures on existing buildings, namely prestressed reinforcement cross-piece anchoring.
SUBSTANCE: method involves installing thrust members to be connected to structure member to be reinforced with coupling bolts. Support parts of anchors are made as steel compression collars with stop stages to receive eye screws of cross-pieces. Compression collar is made of composite clips provided with thrust ribs at end parts thereof. Thrust ribs comprise coupling bolts. Inner clip surfaces are subjected to treatment to increase static friction force. After bringing cross-pieces into operation metal members of anchors are covered with fire-protective composition.
EFFECT: provision of joint operation of anchor and object to be reinforced, increased load-bearing ability of anchors and member to be reinforced, increased fire protection of steel components included in anchors.
