Title: Colleen M Kerkay: Innovator in Reinforcing Bar Technology

Introduction

Colleen M Kerkay is a notable inventor based in Olmsted Township, OH (US). She has made significant contributions to the field of construction and engineering through her innovative designs and patents. Her work focuses on enhancing the strength and reliability of reinforcing bar connections.

Latest Patents

Colleen holds a patent for a "Reinforcing bar connection and method." This invention features a high-strength reinforcing bar splice that utilizes a contractible jaw assembly to bridge the bar ends that need to be joined. The jaw assembly is equipped with interior teeth designed to bite into the projecting ribs or deformations on the outside of the bar ends. This design ensures a secure connection while maintaining the integrity of the bar's core diameter. The assembly is constricted from both axial ends by driving tapered locking collars, which lock the jaw assembly in place once the tool is removed. This splice not only provides high tensile and compressive strengths but also exhibits good fatigue and dynamic strength, qualifying it as a Type 2 coupler.
