DEVICE TO FIX BUILDING STRUCTURE IN SOIL AND METHOD OF FIXATION AND WITHDRAWAL OF DEVICE TRACTION ROD FROM SOIL Russian patent published in 2013 - IPC E02D5/80 

FIELD: construction.

SUBSTANCE: device comprises an extracted anchor traction rod, protected against contact with a hardening material with a shell, a fixator of the anchor traction rod, embedded into the anchor root with the hardening material, in the fixator body coaxially to the anchor traction rod there is a seat, protected against ingress of the hardening material in it, where a clamp is installed, made of segments that cover the end of the traction rod. At the outer side the segments in the folded form have a shape that responds to the seat shape. The seat of the body and clamp segments form a pair that clamps an anchor traction rod or weakens the clamping force, the extracted anchor traction rod at least on a section introduced into the fixator body is equipped with a power helical profile, which is covered with a split nut, the cut in which is aligned mostly in direction of the longitudinal direction of the anchor traction rod. Inside the body of the fixator there is a stop that prevents rotation, preferably, composite one, of the split nut relative to its longitudinal axis and not preventing longitudinal displacement of the nut in the fixator body in direction of the longitudinal axis of the anchor traction rod. Versions of device realisation are presented.

EFFECT: increased reliability of anchor traction rods withdrawal, which are made of reinforcement rods of periodical profile.
