Abstract

The shoring prop contains a telescopic tubular piece with top support-plate, and a series of pairs of holes axially equidistant, through which is inserted a locking-pin resting on the top collar of the tubular shaft. The bottom part of the tubular shaft is connected, by means of a screw-jack, to a tubular base with base plate. The screw-jack consists of a threaded rod touching the base of the shaft. The top of the base has a closing-device in the form of a metal ring. The outside of the shaft has a handle on two sides for moving the tubular shaft along its lengthwise axis.
