System and method for forming flush joints between adjacent wallboard panels

Abstract

A system and method for forming flush joints and improving the shear strength in wallboard panels are provided. The system includes using a clamping mechanism to apply simultaneous opposing pressure against the butt joint area so as to cause the edges of adjacent wallboard panels to align level with the plane of the drywall panels. In certain implementations, the system utilizes an elongated tie strap to interconnect a back support disposed on the back side of the drywall panels with a tensioning device which is disposed on the front side of the panels. Adhesive prepackaged in packets can be used to attach the back support to the drywall.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention generally relates to systems and methods for installing wallboards, and in particular, relates to a system and method that can be used to form flush joints between adjacent wallboard panels and improve the overall shear strength of the finished drywall.[0003]2. Description of the Related Art[0004]Various drywall installation systems have been developed to create level and smooth drywall joints. Joint compound and tape are typically applied to the joint area to conceal the seam between two drywall panels. Joint areas formed by abutting the beveled edges of drywall panels are inherently recessed and / or tapered thus can be filled with joint compound and covered by joint tape without creating a visible ridge in the finished drywall. However, joint areas formed by abutting the cut edges of panels, often referred to as butt joints, are usually already level with the plane of the drywall panels. Once joint compo...

AI Technical Summary

Benefits of technology

"The present invention provides a new way to install drywall panels. This system and method have several features that make them different from previous methods. These features work together to make the installation process easier and more efficient. The technical effects of this invention include improved installation speed, reduced labor costs, and better overall quality of the finished drywall panels."

Problems solved by technology

However, the conventional back blocking process is generally costly and time consuming.

These complicated and time-consuming steps often discourage drywall installers from using the back blocking process.

As a consequence, the butt joint areas of many installed drywall are not as flat and smooth as desired.

Gradual movement of the building frame over time due to moisture and other factors can cause deformation of the drywall joint.

Such deformation greatly detracts from the appearance of the finished drywall.
