    摘要： A shoring apparatus has an elongate support post having two ends. One of the ends of the support post is cylindrical while the other end of the support post is provided along its length with spaced apertures. A first telescoping sleeve surrounds the one end of the support post and is slidably mounted on the same, the sleeve having an engaging member or tooth which is adapted to selectively engage and be secured in locking relationship by one of the steps of a stepped rest collar fixed on the support post. The steps on the rest collar are incrementally axially spaced from each other about the periphery of said support post. A second telescoping sleeve has an apertured end and is slidably mounted on the other end of the support post to permit alignment of its aperture with one of the spaced apertures of the support post. A pin is removably receivable in respective aligned apertures of the second sleeve and the support post to prevent relative axial movement therebetween. The distance between each of the apertures in the support post represent a distance approximately equal to the totality of steps of the rest collar. In this manner, the overall length of the shoring apparatus can be adjusted coarsely by aligning respective apertures in the support post with the aperture in the second sleeve, and can be adjusted finely by selectively engaging the tooth of the first sleeve with one of the steps of the rest collar.

    摘要翻译： 支撑装置具有具有两端的细长支撑柱。 支撑柱的一个端部是圆柱形的，而支撑柱的另一端沿其长度设置有间隔开的孔。 第一伸缩套筒围绕支撑柱的一端并且可滑动地安装在其上，套筒具有接合构件或齿，该接合构件或齿适于通过阶梯式止动环的一个步骤选择性地接合和固定在锁定关系中 固定在支柱上。 在其他衣领上的台阶周期性地沿着所述支柱的周边轴向间隔开。 第二伸缩套筒具有有孔的端部并且可滑动地安装在支撑柱的另一端上，以允许其孔与支撑柱的间隔开的孔中的一个对准。 销可拆卸地容纳在第二套筒和支撑柱的相应对准的孔中，以防止它们之间的相对轴向移动。 支撑柱中的每个孔之间的距离表示大致等于其余环的步骤总数的距离。 以这种方式，可以通过将支撑柱中的相应孔与第二套筒中的孔对准来粗调地调整支撑装置的总长度，并且可以通过选择性地将第一套筒的齿与其中一个步骤 的休息领。

    摘要： A shoring frame system is disclosed whereby a pair of generally planar columns are spaced from each other in tandem with the respective legs of each column interconnected by jack heads at the tops and bottoms thereof. Each jack head includes a jack thereon whereby the overall height of the respective legs of each column can be readily adjusted by adjusting a single jack.
