Abstract: A prefabricated unitary body forming an archway is made of a light, durable material. The body includes a corner bead and defines a recess for receipt of a corner bead covering a drywall section which abuts against the bottom walls of the archway. The archway is nailed in place and drywall compound is applied, tapering from the corner bead of the archway to fill and cover the seam joining the archway within a framed opening.
Abstract: Internal walls of building structures include a plurality of longitudinally spaced-apart studs extending vertically between floor and ceiling levels and a horizontally longitudinally extending top-plate atop the vertical studs and extending a finite vertical-depth below ceiling level. Disclosed herein are novel prefabricated modules and methods for defining the upper portion of an arbitrarily selectably shaped archway to be constructed through the building interior wall. The prefabricated modules comprise a pair of parallel upright panels maintained in finite lateral-separation with internal bracing means including vertical rails attachable alongside upper portions of neighboring studs flanking the intended archway. The module also comprises arbitrarily selectably shaped archway delineating means extending laterally between the panels and spaced more than said vertical-dept below the module top-edge and intervening portions of the bracing means.
