Magnetic Concrete Construction Keyway System

Abstract

A magnetic concrete construction keyway system for strengthening adjacent concrete slabs through the use of a reusable and flexible keyway forming apparatus. The magnetic concrete construction keyway system includes a steel form to create a mold for a concrete slab, a keyway member including a connecting side, wherein the connecting side is removably attachable to an inside of the steel form and wherein the keyway member forms a groove in the concrete slab. The keyway member is magnetically attached to the steel form through the use of a plurality of magnets embedded within the keyway member.

AI Technical Summary

Benefits of technology

"The present invention provides a new magnetic concrete construction keyway system that can strengthen adjacent concrete slabs through the use of a reusable and flexible keyway forming apparatus. The keyway member is magnetically attached to the steel form and forms a groove in the concrete slab. The keyway system has many advantages of the prior art concrete strengthening methods and is not anticipated, suggested, or implied by any of the prior art. The invention is not limited to the specific details and can be practiced in various ways. The technical effects of the invention include overcoming the shortcomings of prior art devices, magnetically attaching to steel forms, bending and conforming to curved edges, easy attachment and removal from steel forms, and being adaptable to various keyway joint structures and configurations."

Problems solved by technology

This severely limits the usability of the form in that whenever you use it, you will be forming a groove in the edge of your concrete.

A lot of times, this is not desired.

This can be very time consuming and overall unpleasant work.

Keyway apparatuses are also generally comprised of a stiff material and are not able to conform to steel forms with curvatures or other abnormal shapes.

This can be very expensive and an unnecessary cost.

While these devices may be suitable for the particular purpose to which they address, they are not as suitable for strengthening adjacent concrete slabs through the use of a reusable and flexible keyway forming apparatus.

Past keyway apparatuses are generally fixed in the shape that they are able to conform to and can also be difficult to attach to the forms.
