Abstract
A wall anchor for use in an insulated cavity wall has an elongated body extending from a driven end to a driving end. The driven end is adapted to be mounted on an inner wythe of a cavity wall structure. A rotation control portion of the elongated body may include teeth formed on the surface. A collar with at least one aperture for a veneer tie is located near the driving end. The collar may have a pawl associated with it and positioned to engage the teeth on the elongated body. The teeth of the elongated body and the pawl of the collar form a ratchet structure. The collar can be rotated relative to the wall anchor only in a single direction, with the interengaging ratchet structure preventing rotation in the opposite direction.
Claims19
A wall anchor for use in a cavity wall to connect to a veneer tie to join an inner wythe and an outer wythe of the cavity wall, the wall anchor comprising:
- an elongated body having a driven end, a driving end and a longitudinal axis;
- and
- a collar mounted on the elongated body for rotation about the longitudinal axis of the elongated body, the collar being adapted for connection to the veneer tie;
- rotation control structure operatively engaging the collar and elongate body to permit rotation of the collar in a first direction relative to the elongate body about the longitudinal axis of the elongate body and to prevent rotation of the collar relative to the elongate body about the longitudinal axis of the elongate body in a second direction opposite the first direction;
- the rotation control structure comprising ratchet teeth associated with one of the elongate body and the collar and a pawl associated with the other of the elongate body and the collar.
A wall anchor for use in a cavity wall to connect to a veneer tie to join an inner wythe and an outer wythe of the cavity wall, the wall anchor comprising:
- an elongated body having a driven end, a driving end and a longitudinal axis, the driven end being adapted to be threadedly mounted on the inner wythe of the cavity wall, the elongated body including a rotation control portion having ratchet teeth formed thereon;
- and
- a collar disposed on the elongated body and received on the rotation control portion, the collar having wings each having an aperture therein to receive a respective portion of the veneer tie, the collar comprising a first metal plate and a second metal plate, a pawl associated with the collar and projecting from the collar into engagement with the ratchet teeth, the pawl and ratchet teeth being positioned and configured for engagement with each other for permitting rotation of the collar about the longitudinal axis of the elongated body in a first direction and preventing rotation of the collar about the longitudinal axis of the elongated body in a second direction opposite the first direction.
