Abstract
A wall fastening (1) system for fastening a second wall (3, Fig. 1) to a first existing wall (2, Fig. 1) comprises an elongate rail 4 fastened upright to said first wall (2). A plurality of wall-tie carrying members 6 for wall ties 7 each has a flange 9 engageable with a slot (8) on the rail 4 whereby the carrying members (6) are positionable spaced apart on the rail 4 as a vertical array. The spaced carrying members 6 are firmly secured to the first wall 2 e.g. by wall screws, and the spacing is such that each wall tie carried by the respective carrying member 6 lies between two successive brick courses 6 of the second wall 3. The above system provides a saving in material and also a fastening system of increased rigidity. <IMAGE>

According to another aspect of the present Referring to Figs. 1 to 3 of the drawings, a wall invention there is provided wall fastening apparatus fastening system 1 is shown facilitating the building to facilitate the building of a second wall onto a first 120 of a second wall 3 onto an existing wall 2, and (as existing wall, said apparatus comprising upright shown in Fig. 1) particularly for a second wall 3 attachment means adapted for securement to said extending at right angles to the first. The wall first wall, and carrying means on said attachment fastening system 1 comprises an elongate means for wall ties whereby each wall tie can be positioning member 4 providing an edge flange 5, a positioned between two successive brick or block 125 series of wall-tie carrying members 6 (only one courses of said second wall, characterised in that shown in Fig. 2) which are fitted on the elongate there are provided a plurality of separate individual member 4, and wall tie elements 7 carried by the wall-tie carrying members for wall ties, and an carrying members 6. The parts of the system 1 are of elongate positioning member adapted for metal plate construction, preferably of mild or securement in an upright position on said first wall 130 stainless steel, and can be formed by metal 2 GB 2 191 520 A 2 stamping. member 6 is located in position as shown in Fig. 1 The flange 5 of member 4 is bent over to form a prior to building the course so that the limbs 18 of slot 8 receiving a flange 9 of each carrying member the elements 7 will be at the top level of the course 6; the elongate member 4 being fastened to the wall (or slightly above) and the element 6 is secured in 2 bywall screws 10 passing through holes 11 on the 70 this position on wall 2 by means of fastening screws member 4. Member 4 includes a reinforcing ridge inserted through the screw apertures 28. Further 12. The carrying member 6 is of corrugated plate carrying members 6 are fitted to the member 4 and form and raised corrugations thereof provide screwed to the wall 2 to form a vertical array of apertured land portions 13 for wall screws (not members 6 with selected vertical spacings S,, S2 etc.

Each element 7 is of L-shaped form and is be fitted to the positioning member 4 at the desired stamped out so that the longer limb 18 has side vertical spacings S,, S2 etc. and secured to the wall 2 flanges 19, while the shorter limb 20 of element 7 is 80 prior to the formation of the wall 3. The spacings S, received in slots 16,17 so as to cover the recessed S2 etc would normally be uniform eg. 300 mm. As screw aperture 28 in land 13 (two elements 7 being seen in Fig. 3, the edge flange 5 serves to align the provided for carrying member 6). The wall tie 7 is brick courses. The flange 9 located in slot 8 has consequently firmly gripped between the land 13 sufficient width to prevent tilting of the element 6 so and the strap portions 14,15 such that any free 85 that the elements 6 will be set precisely normal to (pivotal) movement of the tie 7 in the plane of the member 4 and hence horizontal. Similarly tie land 13 or in a plane perpendicular thereto can be elements 7 are restrained from pivotting by slots 16, substantially precluded.

can serve as a clipfor the channel 26. Fig. 4 shows As will be appreciated, the above wall fastening the position of initial fitting of a carrying member 6 100 system of the present invention provides an infinite onto the positioning member 4. In this position the vertical adjustment of the wall tie elements 7 member 6 is inclined relative to the member 4 with relative to the member 4 so that all irregularities in the flange 9 partially in the slot 8, and in this position course levels can be compensated for. Further in the the member 6 is capable of a sliding guided present invention, the wall tie elements are carried movement on the positioning member 4. To lock the 105 by separate carrying members rather than by a member 6 in the positioning member 4, a single integral elongate metal section as in previous downward force F is applied to the member 6 to systems and this enables substantial reduction in cause the channel 26 to clip into channel 25 as the amount of material required for the construction shown in Fig. 5, held by the side walls 25A, 25B of of the wall tie since the elongate member 4 can be the channel 25. 110 relatively narrow. Additionally, the specific and firm A further preferred feature is thatthe limb 18 of securement of each carrying member 6 to the wall 2 the tie element 7 is located slightly above the top by means of the fastening screws give greatly edge of the relevant carrying member 6 and to improved strength to the fastening system in achieve this requirement a stop element 27 is comparison to systems using a single integral provided on the limb 20 of tie element7 as shown in 115 elongate tie attachment member which maybe Fig. 6 and engages an outer edge 13A of the land 13 secured to the base wall only at random positions.
