Support assembly for a core drill

Abstract

A support assembly for a core drill which utilizes an improved high strength spoked reinforcer. The reinforcer may be removably mounted a core drill tube by fasteners. A drive connection is removably mounted and centrally located on an outer disc of a pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The assembly can also include a split in the disc when the high strength spoked reinforcer is not welded thereto, thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith.

Field[0003]The field of this invention relates generally toward cutting implements and more particularly to the construction of a core drill.[0004]2. Related Art[0005]Core drills are commonly used for drilling holes in hard materials, such as concrete and masonry. These holes are then used to support a structural member, such as a post, which is used on a support member for a building structure or for forming a large diameter borehole with the borehole being used for the passage of pipe lines or...

AI Technical Summary

Benefits of technology

This patent describes a reinforcement system for a structure, such as a core drill, that includes a high strength spked reinforcer with a water stop disc to prevent water from passing through. The reinforcement can also be non-planar or have a non-planar component, such as a triangular-cross-section tubular or channel structure, which can be produced by extrusion, roll-formation, or machining. Slanted elements can also be used to improve structural support, which can be monolithic with a spoke, arm, or extension or combined with other elements in the X-Y or Z-axis directions. The patent provides various configurations and methods for creating a reinforcement system for a structure such as a core drill.

Problems solved by technology

Furthermore, there is a certain amount of deflection associated with the use of the core drill.
