DEVICE FOR CREATION OF TENSION FORCE IN STRAPS FROM ROUND STEEL Russian patent published in 2020 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used to increase bearing capacity of stone and reinforced concrete structures or buildings wholly when performing their reinforcement due to reduction and limitation of transverse deformations. Tightening is performed by transverse tightening of parallel-tightening rods fixed on steel supports along structure perimeter. Rods are tightened by means of device made in form of bent bolt passed into steel tube with welded to it loop from rod, similar to bolt, tightened and fixed in working position due to screwing of nut and lock nut located on straight section of bolt and resting against support end of washer tube end.

EFFECT: technical result is improved operational reliability of the structure.
