Definitions

  • This invention relates to wall ties for cavity walls.
  • wall ties have provided a drip formation centrally in the cavity.
  • the metal is bent or deformed downwardly which can cause the compressive strength of the tie to be reduced.
  • this alternative can give rise to weakness of the tie in tension.
  • a wall tie comprising a rigid elongate strip-like member including a pair of end portions adapted to be secured respectively to the inner and outer leaves of a cavity wall; and a cavity bridging portion joining the end portions; the cavity bridging portion of the'tie having a pair of twists adjacent respective end portions, whereby the major part of the cavity bridging portion lies in a generally upright plane in use, the overall profile of the cavity bridging portion including an upwardly arched formation and an inverted arched formation.
  • the arched formations may be of generally U-shape, V-shape or truncated or polygonal.
  • both. end portions are substantially coplanar.
  • the tie may be symmetrical about its mid point and the symmetry may be mirror-image or inverted.
  • the inverted arched profile may lie immediately adjacent the upright arched profile.
  • a further arched profile or inverted arched profile may be provided in addition to said upright arched profile and said inverted arched profile.
  • One or both end portions of the tie may be provided with a mortar key in the form of projections, depressions or cut outs.
  • the wall tie shown in Figures 1 to 3 of the drawings it comprises a metal strip of steel, which is preferably stainless steel but which may be galvanised mild steel.
  • the first and second end portions of the tie are indicated at 11 and 12 and the tie is generally indicated at 10.
  • a central cavity bridging portion of the tie is generally indicated at 13.
  • the end portions 11 and 12 are substantially the same, being formed with a series of chevron shaped projections and depressions 15 to act as a mortar key when the end portions are embedded in the mortar of the outer and inner leaves of a cavity wall respectively.
  • the extreme free end portions of the tie may be rounded at 16 to reduce the risk of injury to a bricklayer which might be caused by sharp corners.
  • the end portions 11 and 12 lie in the same generally horizontally plane in the inner and outer leaves of the cavity wall.
  • the cavity bridging portion 13 lies in an upright vertical plane in use.
  • plan view in Figure 1 it presents only a very thin edge in an upward direction so that any mortar falling from a higher level onto the wall tie is discour- ged from settling and tends to drop off the wall tie without forming a mortar bridge between the inner and outer leaves of the wall.
  • any moisture condensing on the tie tends to run down this thin vertically upright cavity bridging portion.
  • the profile is very similar to that shown in Figure 2 but is reversed end for end. Similarly, if the tie is simply reversed end for end from the position shown, the profile is similar. In each case, there is a pair of moisture drip formations separated by an upwardly inclined arch wholly above the level of the upper of the moisture drip formations. The tie therefore continues to function even if placed in the cavity reversed end for end or upside down.
  • Figure 4a shows a truncated rather than vee shaped arched profile, with an arch 20a, a main downwardly projecting moisture drip formation 18a and a subsidiary moisture drip formation 21a indicated on the drawings. Again, the tie is symmetrical about a dotted line 23a.
  • Figure 4b shows a profile in which the underneath edge 19b of the tie has a pair of arches 20b separated by a main moisture drip formation 18b, the cavity bridging portion also including two subsidiary moisture drip formations 21b.
  • the cavity bridging portion is symmetrical about the line 23b but this is not an inverted symmetry.
  • Each side of the line 23b is a mirror image of the other.
  • Figure 4c shows a profile very similar to that of Figure 2 but with rounded, rather than angled arched profiles.
  • the chevron type mortar key illustrated provides secure fixing against both tension and compression forces when it has been embedded in the mortar of the inner and outer leaf brickwork.
  • This form of mortar key has been found to reduce the risk of vertical and or horizontal cracking of the masonry which may occur when wall ties having other types of mortar key are subjected to strong tension or compression forces, since these forces can be resolved into vertical forces in the masonry.
  • the tie is slender in width compared to other metal strip-like ties. This results in a relative saving in the metal used which may result in substantial cost savings particularly where the tie is to be made of stainless steel. Additionally, however, the tie has sufficient flexibility to be capable of accommodating some small discrepancy in height between the coursing levels of the inner and outer leaves of masonry. In each of the examples illustrated, such minor discrepancies do not have any substantial effect on the mortar or moisture shedding properties of the tie. It is particularly noteworthy that none of the forms of the tie relies solely on a single moisture drip formation which could be pushed out of position by some misalignment in the inner and outer coursing levels.
  • the arched formation need not necessarily be arched at both of its edges.
  • a formation having a flat lower edge and a part circular arched upper edge is to be considered as an arched formation in the context of this specification.
