A framing accessory includes a bead and a backing strip. The bead may comprise a first leg, a second leg, and a lip. The second leg may comprise a plurality of openings. The strip may be attached to the upper surface of the first leg. In some embodiments, the strip may comprise a single layer of material, while in other embodiments, the strip may comprise two or more layers of material. The strip may comprise material having fire resistant, intumescent, and/or sound insulating properties. The finishing accessory may be configured to be installed in a gap at a head of wall joint by positioning the first leg and strip along the top edge of a wallboard panel and the second leg extending vertically downward along the outer surface of the wallboard panel.

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.

A reinforcing mesh element for embedding in a cement matrix of a building structure, preferably in a corner region or in a curved region. The reinforcing mesh element has a grid-shaped arrangement of fiber bundles that are embedded in a plastic matrix. The reinforcing mesh element has at least one rigid zone and at least one flexible zone. In the at least one flexible zone the plastic matrix consists of an elastomer plastic. The plastic matrix comprises in the at least one rigid zone a thermoset plastic. The flexible or rigid form of the reinforcing mesh element is thus obtained, due to the set-up of the plastic matrix. Additional stiffening bodies or stiffening elements that are connected with the grid-shaped arrangement can be omitted. The reinforcing mesh element can be adapted to the respective situation and simplifies handling when manufacturing a building structure.

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.
