Rotary Impact Hammer Drill Stand

Abstract

In commercial and industrial building construction, hand held rotary impact hammer drills (RIHD) are used to bore holes in the underside of reinforced concrete slabs where fasteners are inserted to support piping and ventilation systems. Overhead drilling with RIHD causes extreme physical exertion and hand-arm vibrations while covering the worker in dust and debris. Overhead drilling with RIHD may lead to on-site injuries when the RIHD hits steel reinforcement beams in the concrete. The objective of this project is to design and fabricate a RIHD stand that reduces the physical exertion of the construction worker as well as increases the safety of their occupation. The design should help deflect dust and debris created by the drilling as well as to improve the efficiency of the overhead drilling process.
