2x4 coupling plate

Abstract

The 2×4 Coupling Plate allows two boards to be reversibly coupled so that the lengths of the two boards may be added together. The coupling plates allows both boards to be separated without damaging them. This device allows a concrete fabricator to assembly two 2×4 boards together and hold them together to form a structure to contain liquid concrete. Once the concrete is set, the installer removes the two boards from the coupling plate so that the boards can be used on another concrete form.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application does not claim priority to any prior patent application.DISCLOSURE REGARDING PRIOR DISCLOSURES BY THE INVENTOR OR A JOINT INVENTOR[0002]The inventor has not disclosed this invention more than twelve months prior to the filing of a provisional application to which priority is claimed.BACKGROUND OF THE INVENTION[0003](1) Field of the Invention. This device is a plate or bracket formed of a hard material that allows a user to couple two boards of lumber, such as two 2×4s, at their lengths. This device allows a user to combine a large number of boards at their lengths to create concrete forms. The user utilizes the device to create, for example, a concrete form for the foundation of a home. Liquid concrete is poured into the form and the concrete is allowed to set until hard. Next, the user removes the boards from the 2×4 Coupling Plate. The 2×4 Coupling Plate can then be used to create additional concrete forms. 2×6's, 2×10s...

AI Technical Summary

Benefits of technology

The patent text is discussing the problem of using a large number of lumber pieces to make concrete forms and the high cost of this lumber. The text suggests that there is a need for a device that can quickly and efficiently assemble and disassemble concrete forms, allowing the lumber to be reused. This will save money and help the environment.

Problems solved by technology

None of the joining plates disclosed by Ikerd would allow a user to join two boards together in the horizontal direction.

This device could not be used to create concrete forms.

This device could not be used to make concrete forms because the angled extensions would prevent assembly and disassembly of the concrete form.

Upon disassembly, the lumber used to make the concrete form is typically not reused because of damage sustained by said lumber in making and disassembling the concrete form.

The costs of lumber has risen greatly in recent years.
