Abstract:
Thermally-isolating wall anchors and anchoring systems employing the same are disclosed. A thermally-isolating coating is applied to the wall anchor, which is interconnected with a wire formative veneer tie. The thermally-isolating coating is selected from a distinct grouping of materials, that are applied using a specific variety of methods, in one or more layers and cured and cross-linked to provide high-strength adhesion. The thermally-coated wall anchors provide an in-cavity thermal break that severs the thermal threads running throughout the cavity wall structure, reducing the U- and K-values of the anchoring system by thermally-isolating the metal components.
Abstract:
A high-strength ribbon pintle and cavity wall anchoring system employing the same is disclosed. The ribbon pintle is a wire formative construct that is cold-worked with the resultant body having substantially semicircular edges and flat surfaces therebetween. The edges are aligned to receive compressive forces transmitted from the outer wythe. The ribbon pintles hereof, when part of the anchoring system, interengage with receptor portions of a wall anchor and are dimensioned to preclude significant movement lateral with or normal to the inner wythe.
Abstract:
A wall anchor for use in an insulated cavity wall has an elongated body extending from a driven end to a driving end. A threaded portion at the driven end is adapted to be mounted on an inner wythe of a cavity wall structure. A drive head at the driving end has a surface facing the driven end of the wall anchor, with teeth formed on the surface. A collar with at least one aperture for a veneer tie is located near the driving end. The collar has teeth formed on a top surface generally facing the drive head. The teeth of the drive head and the collar are interengaging ratchet teeth, and a spring washer biases the collar against the drive head. The collar can only be rotated relative to the wall anchor in a single direction, with the interengaging ratchet teeth preventing rotation in the opposite direction.
Abstract:
A backup wall reinforcement with T-type siderail anchoring system is described for use in masonry cavity walls. The reinforcement and integral anchor is hybrid device installed within the backup wall and interlocked with novel veneer ties. The novel veneer ties are manually connected through swinging or twisting the veneer ties until the veneer ties are interlocked with the anchor. Once interlocked, lateral and vertical veneer tie movement is limited strengthening the cavity wall structure. The inclusion of a reinforcement wire within the veneer ties and the exterior wall provides a seismic structure.
Abstract:
A tubule assembly for thermally isolating a surface-mounted wall anchor and an anchoring system employing the same are disclosed. The thermally-isolated tubule assembly is adaptable to varied anchor structures and for use with interlocking veneer ties and reinforcement wires to provide a high-strength surface mounted anchoring system for cavity walls. The stepped cylinders sheath the mounting hardware to limit insulation tearing and resultant loss of insulation integrity. The tubule assembly is thermally-isolated through the use of a series of strategically placed compressible nonconductive fittings and set within the perimeter of the anchor base. Seals are formed which preclude penetration of air, moisture, and water vapor into the wall structure.
Abstract:
Anchoring systems for use in cavity wall structures having an inner wythe and an outer wythe constructed of rubble stone are disclosed. The anchoring system employs an anchor fastened to or set within the inner wythe that extends into the cavity and connects to a J-hook. A vertically adjustable veneer tie enwraps the J-hook, limiting lateral movement and front-to-back displacement, and is set within the bed joint of the outer wythe. The anchoring system minimizes cavity size and provides stability for an uncoursed outer wythe equivalent to that of anchoring systems for standards coursed bed joints.
Abstract:
Anchor and reinforcement devices for a cavity wall are disclosed. The devices are combined with interlocking veneer anchors, and with veneer reinforcements to form unique anchoring systems. All the components of the system are wire formatives, including therewithin truss or ladder reinforcements and the eye extensions. The wall anchor portion of the device is fusibly attached to the exterior of the truss or ladder reinforcement by various metalworking techniques. Beyond the portions of the wire formatives inserted in the backup wall, the wire formatives are optionally reduced in height by cold-working thereof. The combined wall anchor and reinforcement devices are compressively reduced in height for spanning insulation mounted on the exterior of the backup wall. The low-profile portions are disposed between thick strips of insulation and maintain the insulative integrity thereof by preventing air leakage.
Abstract:
A water-shedding flashing for use in a cavity wall is disclosed. The flashing includes a modified textured surface with a super-hydrophobic layer that achieves water contact angles between 120 degrees and 165 degrees. Water and water vapor do not adhere to the flashing, causing the water to bead and fall from the flashing. Such combination results in a flashing that works in conjunction with the exterior channels in the outer wythe to produce an efficient water removal and ventilation system within the cavity wall structure. A labor-saving peel-and-stick adhesive with release sheet for installation on the inner wythe utilizes clear, nondrooling adhesives.
Abstract:
A masonry flashing for use in a cavity wall is disclosed. The flashing has channels for draining water from the cavity while permitting entry of air into the cavity. The top surface of the flashing is covered by a protective member. The protective member is a scrim or, in the extruded form, an overarching portion of the flashing material. The protective member prevents the clogging of channels from mortar droppings and other construction debris. The flashing is shown with a drip edge is formed by extending the flashing beyond the external surface of the outer wythe and, with the edge being foil lined, manually forming the drip edge. A peel-and-stick embodiment described herein utilizes clear, nondrooling adhesives. Flashing accessories, namely, an end dam, an inside corner and an outside corner are also described.
