FIELD: construction, particularly to recover load-bearing reinforced concrete structures damaged by fire.
SUBSTANCE: device comprises two pressing cases, which at least partly unload load-bearing structure member to be recovered by means of eye screws and torque wrenches. Device comprises bolts for reinforced concrete member clasping. The bolts bring together L-shaped clips, which provide 4-6-fold static friction coefficient of anchoring device increase. Strut device is made as pre-stressed steel symmetric branches arranged from 2 or 4 sides of members to be recovered, for instance as compressed truss struts and posts. Device is brought into load-bearing building action by means of tightening nuts of screws fastened to strut bodies.
EFFECT: increased efficiency of compressed member recovery, improved anchoring ability, as well as enhanced reliability and rate of device struts bringing in joint action.
