FIELD: mining industry. ^ SUBSTANCE: device has external longitudinal roods, internal rods shortened relatively to external rods and transverse rods. Consoles of outer longitudinal rods are fixed relatively to support profile by folds. Transverse rods are rigidly connected in places of their contact to outer and inner longitudinal rods. Consoles of outer rods are folded back at angle, repeating angle of slant of side wall of support profile and fixing position of tie-bar on it. All inner rods are made with length, necessary for pressing tie-bar between support profile and enveloping rocks at portion of placement of inner and outer longitudinal rods to place of contact of said consoles at part of their length with end of support profile. ^ EFFECT: simplified construction, lower costs. ^ 2 dwg
