Title: Innovations by Patrick Harrison in Concrete Construction

Introduction

Patrick Harrison is an accomplished inventor based in Prairie Village, KS (US). He has made significant contributions to the field of concrete construction, holding a total of 2 patents. His innovative designs focus on improving the durability and functionality of concrete slabs.

Latest Patents

Harrison's latest patents include a "System of protecting the edges and construction joints of cast in place concrete slabs." This invention features an improved joint edge assembly that utilizes a longitudinal joint rail, preferably made of steel, supported off the ground by formwork. The assembly includes first and second joint edge members connected by interference-type connectors with self-release elements. A series of studs extend downward and outward from each joint edge member into the concrete slabs, ensuring a robust mechanical connection. As the concrete shrinks during hardening, the self-release elements allow the joint to open freely, thus protecting the edges of adjacent slab sections from damage. Additionally, a dowel aligner can be integrated into the assembly for proper positioning of dowels within the slab.

Another patent by Harrison is a "System of protecting the edges of cast-in-place concrete slab on ground, construction joints." This design also features a longitudinal joint rail supported by temporary formwork and secured with mounting brackets. Similar to his other patent, it includes connectors with self-release elements and studs that provide a positive mechanical connection. This assembly offers a self-releasing expandable joint between adjacent slab sections, enhancing the durability of concrete constructions.
