FIELD: construction.SUBSTANCE: tool comprises a guide rod, a tubular grip, inside of which the guide rod is installed, an impact element with a longitudinal axisymmetric hole, where the tubular grip is installed, and a working element. The impact element is arranged as capable of variation of its mass, falling along the axis of the rod and impact action at the working element. The working element comprises a board of permanent thickness, rigidly connected to the guide rod in its geometric centre. One of surfaces of the board is made as capable of perceiving the impact element action, and the other surface of the board is made as capable of fixation of the working element on it.EFFECT: process capabilities are expanded.12 dwg |
