FIELD: mining workings strengthening, anchor supports in particular. SUBSTANCE: aim is to simplify design of anchor rod, to decrease labour consumption for its manufacture and supporting member fixation, to increase productivity in supports mounting operations. Bent out plane of supporting plate has additional plate fixed to supporting plate at angle. In the case supporting plate hole is shifted in respect to axis of symmetry, that passes between the bent-out plane and free end of plate in direction, that is opposite to supporting plate bent-out plane, and rod ends have corrugated surface. EFFECT: simplified design of anchor rod, decreased labour consumption for its manufacture and supporting member fixation, increased productivity in supports mounting operations. |
