    • A peripherally flexible arch for propping rock structure for mining tracks, tunnels or the like is comprised of a plurality of partially overlapped elongated segments, each of which has an end portion extended toward the rock structure, a bottom portion opposite to the end portion, and a lateral flange offset from the end portion laterally and in the direction toward the bottom portion. Clamping devices are arranged at the ends of the overlapping regions of the segments to clamp the segments to each other. The end portion of each lower segment is inserted into a groove formed between the end portion and the flange portion of each upper segment at the side of this segment facing away from the rock structure. Each clamping device has a hook engaged in a groove formed between the end portion and the flange of the upper segment at the side of this segment facing toward the rock structure.
    • 用于支撑用于采矿轨道,隧道等的岩石结构的外围柔性拱形物包括多个部分重叠的细长段,每个细长段具有朝向岩石结构延伸的端部,与端部相对的底部,以及 横向凸缘从端部侧向偏向底部的方向偏移。 夹紧装置布置在段的重叠区域的端部,以将段彼此夹紧。 每个下段的端部插入形成在每个上段的端部和凸缘部分之间的槽中,该槽在该段的背离岩石结构的一侧。 每个夹紧装置具有接合在形成在该段的端部和上段的凸缘之间的凹槽中的钩,其面向岩石结构。

    • An adjustable support column for use between ceiling and floor surfaces of a mine has an outer tube having an outer end braced against one of the surfaces and an inner end and an inner tube having an inner end in the outer tube at the inner end thereof and an outer end braced against the other surface. The tubes are coaxial to an upright axis and a wedge ring carried externally on the inner tube is tapered toward the outer tube and engageable in the inner end of the outer tube for resiliently resisting telescoping of the inner tube into the outer tube with a predetermined force and for permitting telescoping of the inner tube into the outer tube when the tubes are pressed axially together with a force greater than the predetermined force. Formations on the inner tube engage the ring for axially displacing the ring along the inner tube and fix the ring on the inner tube at any of a multiplicity of locations therealong.
    • 在矿山的天花板和地面之间使用的可调节支撑柱具有外管,该外管具有支撑在其中一个表面上的外端,内端和内管在其内端处具有在外管中的内端, 外端支撑在另一个表面上。 管与直立轴线同轴,并且在内管外部承载的楔环朝向外管逐渐变细并且可接合在外管的内端中,用于以预定的力弹性地抵抗将内管伸入外管中 并且当管以大于预定力的力被轴向地挤压时,允许将内管伸缩到外管中。 内管上的结构接合环,用于沿着内管轴向移动环,并将环固定在内管上的多个位置的任何位置。

    • An adjustable column for use between ceiling and floor surfaces of a mine has an outer tube having an outer end and an inner end and an inner tube having an inner end in the outer tube at the inner end thereof and an outer end. The tubes are coaxial to an upright axis and an external screwthread on the outer-tube inner end fits with an inner screwthread on the inner-tube inner end so that the tubes can be screwed relative to each other to change the axial length of the column. One of the outer ends is operatively braced against one of the surfaces and the other outer end is spaced from the other of the surfaces. A resiliently compressible support element is braced axially between the other outer end and the other surface.
    • 在矿山的天花板和地板表面之间使用的可调节柱具有外管和外管,外管具有外端和内端,内管在外管的内端具有内端和外端。 管与直立轴线同轴,外管内端的外螺纹与内管内端上的内螺纹配合,使得管可以相对于彼此拧紧以改变柱的轴向长度 。 一个外端可操作地支撑在其中一个表面上,另一个外端与另一个表面间隔开。 可弹性压缩的支撑元件在另一外端和另一表面之间轴向地支撑。
