Abstract

The wall tie comprises two elongate strips. The first elongate strip 10 has a channel formation 14 at one end which terminates in an upstanding portion 16 and a projection 18 which extends partway across the channel. The second elongate strip 12 has a central aperture 20 at one end. In use, the wall tie can be secured by locating the end 26 of the second strip under the projection of the first strip at an angle and then rotating the second elongate strip downwards relative to said first elongate strip, such that the upstanding element is received in the recess. The projection may be formed as a stamped out portion of the wall of the channel formation and may be opposite the upstanding element. Apertures 24 may be formed in the elongate strips to provide a key for mortar.

Description

Wall tie The invention relates to a wall tie for use in connecting the two leaves, that is to say the outer and inner leaves, of a cavity wall together, in particular where one leaf is to be built prior to the other and it is desired to avoid the hazard which exists when ties of any substantial length project from a single leaf and the other leaf is still to be built. It is common practice to avoid this hazard by using two-panties but those used in the past have been expensive to produce or time consuming in use, and have not always been able to be fitted together firmly.

According to the invention, there is provided a wall tie made of two elongate strips capable of being simply and easily connected together, a first elongate strip having at one end a channel formation terminating in an upstanding element, and having also a projection extending partway across said channel formation towards said upstanding element, and a second elongate strip having at one end a central aperture a measured distance from a forward end of the strip, the arrangement being such that, to connect the two strips together, a user will first bring the one end of said second strip into a position in which it extends at an angle across the channel formation of said first strip such that it overlies the upstanding element of the first strip and extends under the extreme end of the projection extending partway across said channel formation, the user then rotating said second strip downwards to bring the two strips into alignment, this causing the aperture in said second strip to receive the upstanding element of the first strip and causing also an upper end surface of said second strip to abut against the underside of said projection. The arrangement may also be such that the action of rotating the second strip downwards to bring the two strips into alignment will cause the end wall of said second strip to abut against the inside surface of the channel formation of the first strip, causing an end portion of said second strip to become wedged between said inside surface at the one side of the channel formation and the upstanding element at the other side.

The upstanding element of the first strip will preferably be formed as a wall extending across a mid-portion of the strip, the aperture in the second strip through which, in use, it is to extend will then be of rectangular shape, being of an appropriate width and length to receive the upstanding element of said first strip without difficulty.

The projection extending partway across the channel formation of the first elongate strip may be a stamped out portion of the side wall of said channel formation opposite the upstanding element.

In the accompanying drawings, which illustrate, by way of example, a particular embodiment of the invention:-Figure 1 is a side view of the two parts of a wall tie embodying the invention, Figure 2 is a plan view of said two parts, Figure 3 is a perspective view on one end of one of the two parts, and Figures 4 and 5 are enlarged side and plan views illustrating the way in which the two parts can be connected together.

Referring now to Figs. 1,2 and 3 of the drawings, the wall tie there illustrated is made of two elongate metal strips, generally indicated 10 and 12.

The first elongate strip 10 has at one end a channel formation, generally indicated 14, which terminates in an upstanding element 16. The upstanding element extends across a mid-portion of the strip and, as seen in Fig. 3, where at its lower end it blends into the channel formation 14, it is flanked by shoulder portions 17. Also at the mid-portion of the strip, and opposite said upstanding element, there has been formed a projection 18 extending partway across the channel formation, said projection having been stamped out from a portion of the channel wall.

The second elongate strip 12 has at one end a central aperture 20 which is located a measured distance from a forward end 22 of the strip. As shown, said aperture extends transversely of the length of the strip.

The outer ends of both of the elongate strips are shown to have a row of apertures 24, these being provided so that, in use, mortar being used for the laying of courses of bricks can flow through and around those end portions to firmly anchor them in place. However, it will be understood that the two parts, V -4-in particular the part 10, may be differently formed depending on the type of wall to which it is to be connected.

To connect the two strips together, a user will first bring the second strip 12 into the uppermost position shown in chain-dotted lines in Fig. 4. (It will be seen that in this position, when touching the bottom of the channel formation and extending At an angle across it as shown, the strip overlies the upstanding element 16 and extends under the extreme end of the projection 18). The user will then rotate said second strip downwards to bring the two strips into alignment, this causing the aperture 20 in said second strip 12 to receive the upstanding element 16 of the first strip 10 and causing also an upper end surface of said second strip to abut against the underside of the projection 18.

Simultaneously, the portions of the second strip flanking the aperture 20 are caused to seat upon the shoulder portions 17 of the first strip.

When fitted together in the manner just described it is found that the two strips are very firmly secured without any free movement and this is because the end wall of the second strip 12 abuts against the inside surface of the channel formation of the first strip 10, causing an end portion 26 of said second strip to become wedged between said inside surface at one side and the upstanding element 16 at the other.

Thus there is provided a wall tie which when used avoids the hazard of e elongate strips extending a substantial distance from a standing first wall.

Various modifications may be made. For example, it will be understood that the other ends of both of the strips 10 and 12 may be of whatever form is required in any particular building work.

Claims
