A cornerbead for drywall construction having an elongated strip with a longitudinal nose bent at a substantially right angle and having a left side and a right side extending outwardly from the longitudinal arcuate nose; at least one raised portion extending the length of the left side; and at least one raised portion extending the length of the right side.

A cornerbead for drywall construction according to one embodiment having an elongated strip bent at a substantially right angle to form an upper portion having an upper edge and a lower portion having a lower edge; and at least two triangular cut out projections along the upper edge and at least two triangular cut out projections along the lower edge.

The present disclosure relates generally to building surface joint supports, for example, configured to bridge and support the seam between two building surface panels. The present disclosure relates more particularly to a joint support configured to support a joint between building surface panels. The joint support includes a longitudinal support strip including a first end, a second end, a first side edge, a second side edge, an inner surface, and an outer surface. An inner layer of adhesive is distributed over the inner surface of the longitudinal support strip and is configured to bond with a joint compound. The adhesive of the inner layer includes a polysaccharide.

Described herein is a drywall apparatus and method. The apparatus includes a finishing drywall liner, a framing drywall liner, a first gypsum-containing segment between the finishing drywall liner and the framing drywall liner, and a second gypsum-containing segment between the finishing drywall liner and the framing drywall liner. The first segment and the second segment are connected by a hinge formed from the finishing drywall liner and the framing drywall liner to allow an angle between the first segment and the second segment to vary.

A construction element is provided for forming a corner of a surface of a building, the surface including wall panels attached to framing studs. The construction element includes: a corner-forming surface that that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels; and a fastener strip that, in a state in which the corner-forming surface is in its installed position with respect to the framing studs, is substantially parallel to one or more of the framing studs, such that a fastener can attach the fastener strip to one or more of the studs without passing through the wall panel.

A corner drywall section has a drywall corner extending vertically from a floor to a ceiling. Further, the corner drywall section has a first wing extending a first side of the drywall corner at a first angle such that the first wing extends horizontally to a first stud, the first wing extending vertically from the floor to the ceiling and a second wing extending from a second side of the drywall corner at a second angle such that the second wing extends horizontally to a second stud, the second wing extending vertically from the floor to the ceiling, wherein the drywall corner, the first wing, and the second wing are a unitary piece of drywall.

A construction element is provided for forming a corner of a surface of a building, the surface including wall panels attached to framing studs. The construction element includes: a corner-forming surface that that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels. The construction element may be provided in multiple sections that are placed end to end and connected together.

A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

A wallboard-fastening device for securing first and second wallboards to a framing member in an outside-corner configuration includes: first and second framing panels that connect to each other to form an inner corner seam that fits against the framing member; first and second corner panels that connect to each other to form an outer corner seam; a first bridge panel that connects to (i) the first corner panel to form a first outer seam and (ii) the inner corner seam; a second bridge panel that connects to (i) the second corner panel to form a second outer seam and (ii) the inner corner seam; a first flat-spring flange that connects to the first outer seam to form a first channel sized to accept the first wallboard; and a second flat-spring flange that connects to the second outer seam to form a second channel sized to accept the second wallboard.

A formable trim strip for use in connection with drywall applications includes two or more layers, including a trim strip body and a backing paper. The trim strip body extends along a body axis and has a top surface and a bottom surface. The trim strip body comprises a polymer material. The backing paper includes a portion secured to the bottom surface of the trim strip body without an intervening layer of adhesive material. The trim strip body is coated onto the portion of the backing paper when a temperature of the trim strip body is within the melting point range such that the bottom surface of the trim strip body contacts the portion of the backing paper. As the trim strip body cools to a temperature below the melting point range, the portion of the backing paper bonds to the bottom surface of the trim strip body.
