A wall anchorage device for use in building an extension wall of bricks or building blocks onto a face of an existing wall structure (32) comprises an elongate plate (8; 8a) having a generally flat body portion (10) formed with an upstanding integral longitudinal flange (14) along one edge. In use, the plate is fixed in a vertical orientation to the face of the existing wall (32) so that the longitudinal flange (14) provides. a guide for locating and aligning the end bricks or blocks (29) of the extension wall (30) as these are laid in position in abutting relationship with said body portion (10). The plate (8; 8a) is formed in said body portion (10) with a series of longitudinally directed integral elongate tongues (16; 16a, 16b) spaced apart at intervals and raised at a shallow angle to the plane of the body portion (10). These tongues (16; 16a, 16b) can be bent outwards after the plate is fixed in position during use so as to project substantially at right angles in a horizontal plane so that they can extend into and be embedded and keyed into the joints between adjacent courses of the extension wall (30) during construction thereby to serve as integral wall tie elements. |
