摘要
The multi-section countersunk glued anchoring device is made of steel, wood, plastic etc. It is used for consolidation of stone, particularly in the floor of a deep mine tunnel, using cartridges of glue, and with connecting components inside the borehole transmitting pull and thrust forces. The components (4, 5) at each end of a device section (1a) have ramp faces (4) formed by recesses becoming wider towards the end, and two thrust transmission faces (7). A wedge (5) is formed in one ramp face, running in the lengthwise direction, and a mating recess in the other.
