An improved corner bead clip is provided for use in attaching corner beads to structural steel members where fireproofing material can be applied to the corner beads. The clip includes jaws that can attach to the steel members with a friction fit, and a body attached to the jaws where the body has notches for receiving longitudinal wires of the corner beads to hold them in place.

The present invention relates to a polymeric cove base support for installation where flooring meets a wall, comprising extruded straight portions and molded exterior corner and end portions. The cove base support comprises an upper wall portion, a lower toe portion and an intermediate curved or concave cove. The wall portion is substantially perpendicular to the toe portion. The curved cove comprises an outer cove surface for facing the wall-floor interface and a spaced apart inner curved cove surface facing the room when installed. The spacing between the two curved coves for the straight portion creates an open area, where the open area includes a supporting or reinforcing bar juxtaposed between the curves, preferably positioned perpendicular between the two curve coves in the center region of the open area, and extending the length of the cove base. The corner and end portions have outside surfaces facing the wall and a floor, the outside surfaces defined in part by spaced ribs extending perpendicular to each of the toe and wall portions.

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 ventilation screed includes a base panel configured for attaching at a vertical wall structure. A first flange extends from the base panel and includes a first side and a second side. A second flange extends from the first side of the first flange and partially along the base panel. A third flange extends from the second flange along the first side of the first flange and spaced from the first flange. A terminal end of the third flange is spaced from the base panel. A spacing element is disposed at the second side of the first flange and includes a convex surface. With the base panel attached at the vertical wall structure, the convex surface is between the first flange and a horizontal surface perpendicular to the vertical wall structure and the convex surface flexes to accommodate movement of the horizontal surface relative to the ventilation screed.

The corner cover for a trim member of a building wall siding or cladding may have first and second panels each with opposed substantially planar faces inclined at an included substantially right angle to each other with a longitudinally extending vertex. Each panel may have a substantially linear bottom end extending substantially perpendicular to the longitudinal vertex. The lower portion of each panel may have a first edge portion spaced from and extending substantially parallel to the longitudinally extending vertex and an upper portion with a second outer edge portion at least in part spaced from and closer to the longitudinally extending vertex than the first edge portion and at least in part may be inclined to both the bottom and first edge portions of its associated panel.

The present invention relates to drywall paperbeads, particularly drywall paperbeads for use in protecting exposed drywall surfaces having non-planar surface contours in an edge region adjacent the drywall edges. The paperbead includes an elongated core having an inner surface and an outer surface, an elongated paper strip having an inner surface and an outer surface, a thickness of between 6 and 7 mils, a weight of between 110 and 125 grams/square meter (gsm) and a porosity of 30 to 130 Gurley sec. The inner surface of the paper strip is roughened and bonded to the outer surface of the core. The outer portion of the thickness of the paper strip is impregnated with a strengthening compound, preferably a polymer strengthening compound, more preferably a latex strengthening compound in an amount of between 3.5% and 13% of the total weight of the paper strip. The width of the paper strip is greater than the width of the core such that at least one edge of the paper strip extends laterally beyond the edge of the core to form a wing on at least one edge of the paperbead. The wing of the paper strip of the paperbead follows the non-planar surface contour of the drywall in the edge region adjacent the drywall edge.

A re-moistenable adhesive-coated drywall corner trim piece having an elongated semi-rigid core piece with a right and left flange, where the semi-rigid core piece has a centerline along which the flanges meet forming a hinge that can be bent and re-bent to any angle any number of times. The piece can also include a step running longitudinally along each of the flanges that can be located between the centerline and the flange edges so that the flanges change from a thicker portion toward the centerline to a thinner portion toward the edges making the piece boxable (capable of being wet mudded simultaneously on both sides without an intermediate drying step). Flanges can be curved slightly inward for perfect bonding.

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 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 building profile having a first and a second strip-shaped profile leg and a connecting section which connects the first profile leg and the second profile leg in the longitudinal direction, wherein the profile legs form a profile angle. At least one of the profile legs has material apertures which are produced from through cuts by a stretching process. A method for manufacturing such a building profile; an installation for manufacturing a profiled strip comprising material apertures which forms a building profile precursor from which said building profiles are produced; an installation for manufacturing such a building profile from a profiled strip comprising material apertures which are produced from through cuts a stretching process; an apparatus for manufacturing such a building profile from a raw strip; and the use of an installation in the production of building profiles, in the form of angle profiles for protecting wall edges or corners or in the form of quick-plastering profiles or in the form of support rails or stand profiles, in the production of building profiles mentioned at the outset.
