Drywall joint fixture and method

Description

BACKGROUND OF THE INVENTION

This invention relates to structure of drywall joints for corner beads, arches, edges, flats and other drywall applications after the drywall has been positioned.

Drywall cornering, beads and joints are a common feature of construction of private and many commercial dwellings and business structures. Numerous devices and methods for joining drywall at corners, arches windows and flats are known, but continue to be devised because none have proved sufficiently adequate to satisfy needs of this feature of construction. Included have been freehand plastering and many differing rigid corner beads, paste-on beads, tack-on beads and combinations thereof.

None, however, have post-positioning corner beads and joints for all drywall applications in a manner taught by this invention.

SUMMARY OF THE INVENTION

Objects of patentable novelty and utility taught by this invention are to provide a drywall-joint fixture and method which can decrease costs for installation of all forms of drywall construction substantially.

This invention accomplishes these and other objectives with a drywall-joint fixture and method having a drywall-joint cover that can be attached to a drywall joint, arch, wall flat or other drywall structure after drywall is positioned on wall framework of a building and before the drywall and the drywall-joint cover are surfaced with paint or other wall cover. The drywall-joint cover has a surface covering for each of at least two drywall surfaces to be covered by a single drywall-joint cover. Intermediate a front surface covering and a side surface covering of the drywall-joint cover is an attachment flange for being extended from an inside surface of the drywall-joint cover and inserted between an end edge of a first drywall and a joint edge of a second drywall. Fastener shanks are affixed through a side drywall and into the wall framework. The attachment flange is inserted between the end edge of the first drywall and the joint edge of the second drywall. Then a side-surface covering is positioned on and fastened to the side-positioned drywall and a front-surface covering is positioned on and fastened to the second drywall.

The above and other objects, features and advantages of the present invention should become readily apparent to those skilled in the art from reading the following detailed description in conjunction with the drawings wherein illustrative embodiments of the invention are shown and described.

The drywall-joint fixture of claim 31 wherein: the first sheet and the second sheet are predeterminedly juxtaposed at a straight angle; and the fastener shanks are positioned orthogonally in the second side; the cap backer is extended from opposite ends of the second side; and the juxtapositional attachment frame is attached to the cap backer.
37. A drywall-joint fixture comprising: a dual drywall-joint cover having an attachment base that is orthogonal to a first attachment flange and a second attachment flange that are extended from an attachment side of the attachment base; a paper face that is resistant to sanding on the drywall-joint cover; a first cover wall extended from proximate a first end of the attachment base; a second cover wall extended from proximate a second end of the attachment base; and the first cover wall and the second cover wall being predeterminedly shorter than the first attachment flange and the second attachment flange in distance of extension from the attachment base.
38. The drywall-joint fixture of claim 37 and further comprising: slots in an end of at least the first cover wall.
39. The drywall-joint fixture of claim 37 and further comprising: slots in an end of at least the first attachment flange.
40. A method comprising the following steps for using the drywall-joint fixture of claim 2:affixing the first sheet and the second sheet of the drywall to the wall framework; allowing a predetermined amount of space to remain between a side of the first sheet and an end edge of the second sheet of the drywall when being affixed to the wall framework; inserting the attachment flange into the space allowed to remain between the first sheet and the second sheet of the drywall; positioning the first side of the drywall-joint cover in juxtaposed contact with an outside surface of the first sheet; positioning the second side of the drywall-joint cover in juxtaposed contact with an outside surface of the second sheet; driving a selected plurality of the fastener shanks into and through the fastener-edge area of the first sheet; driving the selected plurality of the fastener shanks through the attachment flange; and driving the selected plurality of the fastener shanks into the wall framework.
