    • A shoring post having first and second post parts that cooperatively define a variable effective length, a quick release assembly, and a movable pin that in an operative position limits movement of the first post part in one lengthwise direction relative to the second post part. The quick release assembly has: a) at least a first surface against which the pin bears with the pin and quick release assembly in a first operative relationship; and b) at least a second surface against which the pin bears with the pin and quick release assembly in a second operative relationship. The shoring post further has at least one repositionable member that is changeable selectively between: a) a locked state to prevent the pin and quick release assembly from changing from the first operative relationship into the second operative relationship; and b) a released state.
    • 具有协同地限定可变有效长度的第一和第二后部部分的支撑柱,快速释放组件和可操作销,所述可动销在操作位置限制第一柱部件相对于第二柱部件沿一个长度方向的移动。 所述快速释放组件具有:a)至少第一表面,所述销以所述销和快速释放组件以第一操作关系与所述第一表面对齐; 以及b)至少一个第二表面,所述销在所述第二操作关系中与所述销和所述快速释放组件相对着所述第二表面。 所述支撑柱还具有至少一个可重新定位的构件,所述至少一个可重新定位的构件可在以下情况之间选择性地变化:a)锁定状态以防止所述销和快速拆卸组件从所述第一操作关系变为所述第二操作关系; 和b)释放状态。
