Abstract

The wall tie is formed from a strip of metal 10 having two twists 11, 12 between its ends. The twists encourage moisture to drip off the tie and define therebetween a central vertical strip portion 13. The horizontal ends of the tie are bifurcated and an insulation locating member 16 is mounted on the central strip portion as a tight sliding fit. Member 16 may be a disk or a plate having 3 or more sides. <IMAGE>

Description

SPECIFICATION Wall tie The present invention relates to wall ties and is particularly concerned with a wall tie which includes meansforholdinga sheetofinsulationagainstthe inner surface of one leaf of a cavity wall.
According to the present invention, there is provided a wall tie for a cavity wall, comprising a strip of metal which has been turned attwo positions intermediate its ends through 90" or substantially 90" to form respective twists which define therebetween a central strip portion angularly displaced by 90" or substantially 900 with respect to two end strip portions and which in use encourage moisture to drip off the strip into the cavity, each end strip portion having a bifurcated free end and there being provided a disc or plate shaped insulation locating member which is mounted on the central strip portion for slidable movement therealong and which extends transverse ly to the longitudinal axis of the central strip portion.
Preferred and/or optional features of the invention are setforth in claims 2-6.
The invention will now be more particularly described with reference to the accompanying drawings, in which: Figure lisa plan view of one embodiment of a wall tie according to the invention; and Figure 2 is a viewfrom the lower end of Figure 1.
Referring nowto the drawings, the wall tie shown therein comprises a strip of steel 10 which has been turned attwo positions intermediate its length through 90" to form respective twists 11 and 12. The twists 11 and 12 are equidistantly spaced from the two ends respectively of the strip and the twists define therebetween a central strip portion 13 which is angularly displaced by 900 with respect to two end strip portions 14 and 15. As shown in the drawings, the two end strip portions 14,15 are turned relative to the central strip portion l3inthe same angular direction (i.e. anticlockwise in Figure 2), when viewed from one end of the tie and along the length of the tie.
Thefree end of each end strip portion 14,15 is bifurcated,this having been achieved by splitting the ends ofthe portions 14,15 and the bifurcated ends are in use embedded in mortar in opposite leaves of a cavitywall sothatthe end strip portions 14 and 15 lie in a horizontal plane and the central strip portion 13 lies in a vertical plane.
An insulation locating disc 16 is mounted on the central strip portion 13. The disc 16 is preferably of plastics material and as shown comprises a circular rim 17withtwo integral chordal bars 18and19 extending parallel to one another and being equidistanly spaced from and on opposite sides of the centre of disc 16. Integral reinforcing or bracing elements 20 and 21 are provided between the chordal bars 18 and 19 and the rim 17. The chordal bars have, midway between their ends, facing grooves 22 and 23 into which opposite edges of the central strip portion 13 are snap-fitted.
In orderto mountthe disc 16 on the central strip portion 13, it is fed over one end strip portion 14or 15 with the end strip portion between the bars 18and and19; it is then fed over one twist turning itasthis done and onto the central strip portion 13, where it is turned angularly until the edges of the central stripportion"13': snap into the grooves 22 and 23. In this position the disc 16 can be slid along the central strip portion 13 but it will be a tight enough fit as not to allow it to beçåsily moved. Therefore, the disc 16 will be capable of holding-a sheet of insulation against one of the leaves ofthe cavity wall.Moreover, after building the tie into both leaves of a cavity wall, the disc will be captive on the tie and can only be removed by destroying the disc ortie.
With the aforesaid provision of two twists 11,12 at least one will remain exposedandwillserveto encourage moisture to drip intb the caVitytb thus-' preclude or at least substantially reduce the possibility of moisture leakage between the ends ofthetie.
The insulation locating member need not necessari- ly be disc shaped, but may instead be a plate-shaped.
