ABSTRACT:
An anchoring device comprises an elongate tubular body, a plunger axially movable in the bore of the body to operate gripping means in the form of transverse dog plates which axial movement of the plunger causes to project through openings in the body to engage the surface of a hole drilled in a structure to which the device is to be secured.
The anchoring device may be a wall tie with gripping means at each end to engage co-axial holes in two leaves of a cavity wall. Alternatively one or each gripping means may be replaced by a waisted, windowed portion of the wall of the body to be secured in the hole by synthetic resin. Means may be provided for connecting a grip-testing device to the wall tie and a modification allows the grip of one gripping means to be tested before the other is operated.
