Abstract

A wall tie comprises two members, each of which can be connected to a wall, and which cooperate to resist compression and tension forces. As shown, one tie portion comprises a triangular head 3 for embedding in masonry, shank 2 and eye 1 which co-operates with a hook on the other tie member to give a composite tie with some rotational tolerance. An alternative end of generally S-shape as shown in Figure 7 is adapted to be fixed to a timber stud using nails at 8, 9 and 10. Use of these two -part ties leaves no protruding sharp edges following construction of the first leaf of the wall.

Description

24 1 4247 This invention relates to a wall tie which has extra personal

safety during installation and allows some constructional abnormalities to be directly absorbed.

A common form of wall tie consists of one piece of metal bent into shape with complex manufacturing processes. It connects two leafs of a wall together. They often have sharp edges which protrude from a leaf of the wall during construction. Also, the position and type of outer leafhas to be predefined before the wall ties are built into the inner skin. Where the construction material varies on the outer skin between masonry and timber or another material careful selection ofthe tie type needs to take place. This invention allows it to be altered to suit the outer skin as the construction changes from place to place.

This present invention is a wall tie comprising of two members. One member connects to the inner leaf of a wall and the second member to the outer leaf in a fashion that resists both tension and compression loads. The initially separate members join together with an interlocking joint that does not allow extension or contraction of the assembled tie. As the joint permits pivotal movement there is an allowance for inaccuracy in the position of the second leaf in both planes.

If the second leaf is built at a slightly different height or the attachment point is offset, then the joint allows re-alignment into the new position.

The wall tie is progressively installed, one member is embedded in a leaf of the wall causing it to protrude from the first leaf towards the intended position of the second leaf. The protruding portion has no sharp edges thus increasing the safety of this installation. The second member is then connected by an interlocking joint and embedded in the second leaf. The members can be interchanged to allow connections; between masonry or timber/steel elements. Can be of varying lengths and be with or without a drip section. This allows the one wall tie to serve many different purposes. The timber or steel studs fixing also allows connections to be made when the distance between the two leaves varies.

The invention will now be described by referring to the accompanying drawings: Fig 1 Plan view of member A Fig 2 Plan view of an alternative first member showing a different end section Fig 3 Side view of member A with the end section as in fig 2 Fig 4 Plan view of member B Fig 5 Side view of member B as shown in fig 4 Fig 6 Plan view of the two members showing the pivotal movement of the interlocking joint.

It shows the end portion 4 for member A and the end portion 3 for member B. Fig 7 Side view of the member in Fig 6 Fig 8 Plan view of the two members, both with end sections 4.

Fig 1 shows member A with three sections an end portion 1, a middle portion 2 and another end portion 3. The end portion 3 consists of a metal bar bent into a open triangular configuration for attaching to masonry. The end section could be of another typical design such as a inverted S shape with a hook on the end (4) when attaching, to timber. T his is followed by a straight part which leads to a curve (1) of 360 degrees that forms a loop.

Fig 2 shows an alternative to the end portion 3, this connection allows attachment to timber. This alternative end portion (4) consists of an a straight portion followed by a 180 degree turn around a radius of that of the bar and then back through 180 degrees around the same radius. It is then followed by a straight portion and a 180 degrees turn to create a hook.

Fig 4 shows member B with three sections; an end part 5 which is the same as in fig 1, a middle part 6 and another end part 7. The end portion 7 of the member is bent back through 180 degrees with a radius equal to the radius of the bar.

Fig 6 shows that there is an allowance for inaccuracy in the position of the second leaf in both planes as the joint permits pivotal movement.

Fig 7 shows the position of possible nails in the timber connection they can be positioned at 8 and 9 or 8 and 10.

Member A comprises of an elongated section having one end as a closed loop forming a curve that prevents rattling. It is a close fit to the bar diameter of member B causing the bars to be unable to contract or extend.

Member B comprises of an elongated section having one end (7) as a open loop and an central section including a drip if required.

The other end sections, 3, 4 and 5, of the members can be an open triangular, or a closed circular, configuration depending upon its application.

Claims

1. A wall tie with two members, each has a section connected to an inner and a section connected outer wall in a fashion that resists compression and tensile forces.

2. The initially separate members join together with an interlocking joint that does not allow extension or contraction of the assembled tie. The joint accommodates out of plane positions in the vertical and horizontal axis.

3. A wall tie as claimed in Claim I with male and female members.

4. A wall tie as claimed in Claim 3 with an interlocking joint allowing pivotal movement in two planes of the members in relation to each other.

5. A wall tie as in any of the preceding claims with the end structure of one or two members allowing it to be connected to timber. Whilst any remaining end structures comprises of an open triangular configuration.

6. A wall tie as in Claim 1, 2, 3 and 4 claims where the end structure of one or two members comprises of an open triangular configuration. Whilst any remaining end structures comprising of an connection to timber.

7. A wall tie as in any of the preceding claims with either part including a drip.

8. A wall tie as in any of the preceding claims with both members having no sharp protruding edges.

9. A wall tie as in any of the preceding claims with the timber connection allowing different spacings of the wall leafs.

10. A wall tie as described with reference to the accompanying drawings, fig 1, 2, 3, 4, 5, 6, 7 and 8.
