摘要:
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.

A wall bead (100) is provided for application to adjoining surfaces, typically at a corner of a wall, during coating thereof tin with plaster or other render material. The wall bead comprises a central longitudinally extending portion (102) having first and second longitudinal edges; first and second planar panels (104, 106) extending from the first and second edges respectively; and first and second connection portions (108, 110) extending from the first and second panels respectively. The first and second connection portions each comprise a plurality of teeth (114) protruding therefrom. The first and second panels (104, 106) each comprise a flexible mesh such that they are arranged to conform to a contour of a wall surface. The wall bead is adapted to be flexible to suit the needs of varying shapes, angles and surface profiles of a wall, while having a simple and robust attachment mechanism.

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.

Expanded metal lath products, or non-metal facsimile products, are disclosed with moisture resistant pressure sensitive adhesive covered by release sheets, and the use of such products in drywall seaming and their manufacture.
摘要:
Stucco cracks at doors and windows are reduced or eliminated by use of a corner element fastened at a corner juncture before stucco coats are applied. The disclosed corner element spreads out or evenly dissipates differential movement or buckling often occurring at exterior corner junctures. The corner element may comprise various concentric circle attributes useful in stopping or reducing cracks in stucco and related building materials. The corner element embodiments may be secured at widow and door corner areas and then integrated with traditional stucco applications.

The present disclosure is directed to casing accessories for use with multi-component wall systems. Some of the casing accessories of the present disclosure can include a mounting bracket to attach the accessory to a wall structure and a channel formed in part by a spacer that can be adjusted to adjust the channel width in order to encase components of multi-component wall systems that can vary in width from one installation to another. In another aspect, some of the casing accessories can include one or more drainage canals that direct water from one part of the casing accessories to another. In another aspect, some of the casing accessories can impede fire propagation through multi-component wall systems.
摘要:
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.
摘要:
Disclosed are aspects of board finishing systems. For example, in various aspects, disclosed are joint compound compositions, wall assemblies, methods of treating walls, and products related to any of the foregoing, including reinforcement trim, e.g., for protecting corners where boards meet, fasteners, and tape. The joint compound preferably is a drying type composition with reduced shrinkage property, and includes binder and hollow spheres, resulting in an ultra lightweight formulation in some embodiments. The joint compound composition can be applied in a one-coat treatment in preferred embodiments. Other aspects of board finishing system accommodate such a one-coat treatment to thusly allow a user to manipulate the compound closer to the plane of board as compared with conventional formulations. Joint tape and reinforcement trim can include non-swelling synthetic paper facing material in some embodiments.
