摘要: The present invention is directed to a yieldable prop to resist a sagging roof or thrusting floor. The invention is directed to a support apparatus disposed between the floor and the roof. The apparatus comprises a load-bearing member having a length with an axis along the length and having repeating surface undulations along at least a portion of its length. The load-bearing member is capable of moving in the direction of its axis. The apparatus also comprises a resistance member positioned adjacent a portion of length of the load-bearing member. The resistance member resists movement of the load-bearing member by incrementally deforming the undulations on the surface of the load-bearing member adjacent the resistance member as the load-bearing member moves axially.

摘要: A yielding column for support mine roofs or the like includes a tube provided with one or more circumferential rows of slots which provide a preferred locus for buckling. A reinforcing sleeve within the tube prevents inward buckling, so that the buckled portions are easily seen.

摘要: The invention provides a yieldable connection between a metallic rod-shaped body and a holding means through which it passes and is intended particularly for yieldable rock bolts (roof bolts) anchor bolts and yieldable props, e.g. for mining and tunnelling. For that purpose shear bodies, e.g. spheres or inclined cylindrical pins are provided between the holding means and the slidable rod-shaped body and project some distance into the cross-section of the rod-shaped body. On sliding of the latter, in the holding means, these shear bodies form grooves in the rod, whereby energy is absorbed.
