Abstract

A cavity-wail tie has retaining elongate member(s) 10 formed from a strap. Member(s) 10 extend at right angles away from the remainder of the strap and are formed from the strap along one longitudinal side of the strap. The tie is of galvanized metal. If two members 10 are present, one is on each longitudinal side of middle portion 11, and may be bent in the same or opposite directions. In use, after the inner and outer walls have been built to a particular height, a panel of insulation material is placed in the cavity along the inner wall. A series of the ties is then placed bridging the cavity with retaining members 10 downwards and abutting the panels. The walls are then further built upwards, retaining the ties in the cement. <IMAGE>

Description

SPECIFICATION Cavity Wall Tie This invention relates to cavity wall ties for use in bridging the cavity between inner and outer walls of brick, block or the like of a double wall of a building to tie the inner and outer walls together, the ties being held in position in cement between two suprajacent rows of bricks or blocks. Cavity wall ties have heretofore been provided of galvanised metal straps of galvanised wire or of plastics material. This invention concerns cavity wall ties of the type made from galvanised metal straps for which certain standards have been laid down by the British Standards Institute. Each cavity wall tie is formed by one galvanised metal strap which has three transverse portions in end-to-end relationship lengthwise thereof, namely two outer portions separated by a middle portion.Each outer portion has a cut lengthwise thereof, inwardly from the edge of the outer end, and substantially along the longitudinal midway line, which cut causes the two limbs formed thereby to assume a V-disposition. The middle part of the middle portion is bent through 90 angular degrees relative to the remainder of the strap such that part of it extends above and part below the plane in which the outer portions lie, to enable any moisture travelling along the ties from the outer wall or any condensate on the ties, to drip therefrom and thereby be prevented from travelling along to the outer portion of the ties in the inner wall. Due to the desire to prevent or reduce heat loss through cavity walls, it has been proposed to insert panels or blocks of insulation material in the cavity during construction of a double wall.The standards laid down by the British Standards Institute require the panels or blocks of insulation material to be held in the cavity against the inner wall surface. A disadvantage of existing cavity wall ties is that they cannot fulfil this requirement.
It is an object of the present invention to obviate or mitigate the above-mentioned disadvantage.
According to one aspect of the present invention, a cavity wall tie of the type stated is provided with at least one retaining member formed from the strap and extending away from the remainder of the strap.
Preferably, the member is elongated, and formed from the strap along one longitudinal side of the middle portion thereof.
According to a second aspect of the present invention there is provided a method of forming a retaining member in a cavity wall tie comprising the steps of cutting or punching the strap to provide an end and two sides for the retaining member and bending the member about its opposite end such that it lies in a disposition substantially at right angles to the remainder of the strap.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a cavity wall tie according to the present invention; Figure 2 is a plan view of the cavity wall tie; Figure 3 is a side elevation of the cavity wall tie; and Figures4and5are end elevations respectively, in the direction of arrows A and B of Figure 1.
A cavity wall tie of the type stated is provided with an elongated retaining member 10 which is cut or punched from the strap along one longitudinal side of the middle portion portion 11 prior to the middle part 9 of the middle portion 11 being bent relative to the remainder of the strap. The strap is provided with a cut 14 transversely along an imaginary line joining one outer portion 12 and the middle portion 11, and a cut 15 parallel to the longitudinal side of the middle portion 11 and extending from the transverse cut 14 along an imaginary line joining the middle portion 11 to the other outer portion 13. The member 10 is then bent to be at a right angle disposition relative to the outer portion 12 and 13. To accommodate the panels or blocks of insulation material, the outer portion 13 is of greater length than the outer portion 12.
In use, after the inner and outer walls have been built using bricks, blocks or the like to a particular height, a panel of insulation material is placed in the cavity lengthwise of the inner wall. A series of cavity wall ties as above described are then placed bridging the cavity with their retaining members extending downwardly and abutting against the panels or blocks whereby after the next row of bricks or blocks are laid, the outer portions 12 and 13 of the cavity wall ties are secured in the cement between said rows and the panels are held in the required position.
In a modification, two retaining members may be provided, one on each longitudinal side of the middle portion 11 of the strap. Both members may be bent in the same direction or in opposite directions.
The retaining member or members may be of a shape other than that described above and may be punched out of the middle portion art a position other than adjacent to the longitudinal side or sides of the middle portion.
1. A cavity wall tie of the type stated is provided with at least one retaining member formed from the strap and extending away from the remainder of the strap.
2. A cavity wall tie as claimed in Claim 1, wherein the member is elongate, and formed from the strap along one longitudinal side of the middle portion thereof.
3. A method of forming a retaining member in a cavity wall tie comprising the steps of cutting or punching the strap to provide an end and two sides for the retaining member and bending the member about its opposite end such that it lies in a disposition substantially at right angles to the remainder of the strap.
4. A cavity wall tie substantially as hereinbefore described with reference to the accompanying drawings.
