Abstract

The tie consists of a metal strip 1 having one end portion 2 to be bent up for connection with the timber work, the other end portion 3 with an indented surface 5 to key with the brickwork mortar, and centre bridging portion 4 with transverse ridge(s) and/or groove(s) 5, 6, 7 to block moisture travel along the strip and across the wall cavity. Channels 6 and 7 convey moisture away from the timber work and channel(s) 5 convey moisture away from the brickwork. <IMAGE>

Description

SPECIFICATION Wall ties This invention relates to wall ties for use in timber frame with brick cladding or veneer building construction and especially relates to the problem of moisture travel between the timber work and the brickwork of this form of construction.
One known wall tie consists of an elongated strip of stainless steel having a chevron pattern of channels running the length of the strip. In use, one end portion of the strip is bent up for connection with the timber work whilst the other end portion of the strip is embedded in the brickwork mortar. Whilst the chevron channels act to drain moisture sideways off the strip they only act to prevent moisture travelling along the tie against the "V" of the chevron and thus this tie has a drawback of drawing moisture along the tie in one direction and into the mortar if it is installed the wrong way round. Another known wall tie is also made of stainless steel strip and is preformed with the timber work end portion already bent, a transverse ridge across the tie below the bend and dimples in the brickwork end portion to key with the mortar.This tie has the disadvantage of the preforming making it difficult to adjust the tie to the timber work and, whilst the folded ridge acts to block moisture travel along the tie in either direction, it does not act to draw moisture off the tie; indeed water can pool behind the ridge.
It is an object of the present invention to overcome the disadvantages of both these known ties.
According to the present invention, a wall tie for timber frame and brick cladding or veneer building construction consists of an elongated metal strip having one end portion designed to be bent upwards for connection with the timber work, the other end portion provided with an indented surface to key with the brickwork mortar and a centre portion to bridge the wall cavity, the centre portion being provided with one or more generally transverse ridges and/or grooves arranged to prevent moisture travel along the strip and across the wall cavity; the centre portion having one or more channels shaped to convey moisture away from the timber work and a further channel or channels shaped to convey moisture away from the brickwork.
Preferably, the channels are chevron-shaped with the apex of apexes of said one or more channels pointing towards the timber work end portion of the strip and the apex or apexes of said further channel or channels pointing towards the brickwork end portion of the strip; a drainage hole is provided between the oppositely directed channels; and further chevron-shaped channels are provided in the brickwork end portion of the strip to form the mortar keying indentations.
The above and other features of the invention are illustrated by way of example in the Drawing wherein: Figure 1 is a plan of a wall tie in accordance with the invention, Figure 2 is a longitudinal section of the tie of Fig. 1; and Figure 3 is a perspective view of a tie bent into position on a brick.
As shown, the wall tie consists of a thin strip of stainless steel 1 having three portions, a timber work end portion 2, a brickwork end portion 3 and a centre portion 4. A series of chevron-shaped channels 5 are pressed or otherwise formed in the strip and run from the centre portion 4 along to the end of the brickwork portion 3, the apexes of the chevrons pointing towards the brickwork end portion 3. A further two chevron-shaped channels 6 and 7 are also formed in the centre portion of the strip but with the apexes pointing towards the other, timber work, end thereof.
A recessed drain hole 8 is punched or otherwise formed between the chevron series 5 and the "reversed" or oppositely directed chevrons 6 and 7. A pair of nail holes 9 are provided in the timber work end portion 2.
In use, the tie is bent at the junction 10 of the timber work and centre portions 2 and 4 so that the timber work end portion 2 is upright and lies against the timber work (not shown), clearly in bending the tie it is possible to adjust it so that it "fits" the timber work.
The other, brickwork, end portion 3 of the tie is laid on top of a course of bricks, indicated at 11 in Fig. 3; the direction of the chevron-series 5 is such that the channels key with the mortar and tend to resist any forces pulling the tie out of the brickwork towards the timber work, this direction of the chevron also acts to prevent movement of moisture longitudinally along the tie and into the brickwork.
The reverse chevrons 6 and 7 similarly act to prevent movement of moisture along the tie towards the timber work. The drain hole 8 prevents water from pooling between the oppositely directed chevrons 5 and 6, 7.
Conveniently, the ties are packaged with the proper stainless steel annular ring shank nails required to nail the tie to the timber work. Clearly, if the wrong type of nail were to be used, electrolitic corrosion would set in between the tie and the nail. If the ties are manufactured from any other corrosion resistant metal then the appropriate metal nails would be packaged.
