FIELD: construction.
SUBSTANCE: anchor device for a composite rod comprises of a crimp sleeve with a bore and two collets which, folded, shape a cone with a through hole. The inner surface of the crimp sleeve and the lateral surface of the collet cone are designed as a rotation tangensoid. The diameter of the through hole may be smaller than the diameter of the anchored composite rod by 1÷2 mm.
EFFECT: most efficient tension of composite rods due to the uniform anchoring and even force of clamping of them all over the length.
