| (54) | Wall construction device |
| (57) 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. |
