DETACHABLE BARRIER Russian patent published in 2010 - IPC E01F13/00 E01F9/18 

FIELD: construction.

SUBSTANCE: detachable barrier, comprising support plate with anchor part, stand fixed on support plate with the help of split threaded joint and facility to create rotation torque applied to threaded part of stand, differing by the fact that facility for development of rotation torque is arranged in the form of kinematic joint, one of elements of which is part of stand fixed movably relative to remaining part of stand, and the other element is threaded part of stand fixed with the possibility of rotation and longitudinal motion relative to stand and with the possibility of stand end pressing to support plate.

EFFECT: wider field of application of detachable barriers with threaded fixation, increased convenience of operation due to usage of barrier elements themselves as facility for development of rotation torque, increased efficiency of fixation due to direct effect of rotation torque at threaded part of stand.
