TOOL FOR ROUGHENING FACING AND PAVING IN BUILDING AND CONSTRUCTION WORK

摘要

The invention relates to a tool for roughening facing and paving in building and construction work, comprising a rotary shaft (1) connected to a motor that can be actuated using an ergonomically positioned switch and corresponding handles (2a, 2b) for operating same. In addition, flexible rods (3) topped with very hard parts (4) are coupled perpendicularly to the aforementioned rotary shaft (1), along and around the length thereof in an alternating manner. The invention is characterised in this active assembly is positioned inside a cylindrical protective cover (5) having a radius slightly smaller than the length of the rods (3) and said cover (5) is fully sealed except at an opening (5a) designed such that the above-mentioned hard parts can extend therethrough during the rotary movement of the shaft.
