Abstract
The tie is formed from a strip of sheet metal in a single pressing operation. It has two end parts (10, 11), each having therein a mortar retaining depression (12, 13), and an inverted channel section (14) between the end parts. The channel section has a raised portion (16) of generally truncated pyramidical shape midway between its ends for discouraging moisture and mortar collecting on the centre of the channel section. The inclined edges of the raised portion lead to moisture shedding deformations (17) in flanges (15) of the channel section. The channel section also has two upstanding reinforcing elongate webs (18 and 19) one on either side of the raised portion and extending in the direction of the longitudinal extent of the tie. <IMAGE>
Description
SPECIFICATION
A wall tie
This invention relates to a wall tie particularly for tying together the leaves of cavity walls.
According to the invention, there is provided a wall tie pressed from sheet metal and having when viewed in plan two end parts, each having therein at least one depression, and an inverted channel section between the end parts, the inverted channel section having a downturned flange along each of its two opposed longitudinal edges, a raised portion midway or substantially mid-way between its ends and two upstanding reinforcing elongate webs one on either side of the raised portion and extending in the direction of the longitudinal extent of the tie.
Preferably, the tie is formed in a single pressing operation.
Advantageously, the raised portion is of generally truncated pyramidical shape. In this latter case, preferably the downturned flanges of the channel section have a deformation adjacent to the lower end of each inclined edge of the raised portion for shedding moisture collecting on the raised portion. Preferably, the deformations are in the form of laterally outwardly pressed bulges.
Conveniently, each end part is of generally rectangular shape when viewed in plan. In the latter case the edges of the end parts advantageously have a slight concavity in order to assist keying to the mortar and conveniently each end part has a single generally rectangular depression.
The invention will now be more particularly described with reference to the accompanying drawings, in which:
Figure 1 its a side view of one embodiment of a wall tie according to the present invention; and
Figure 2 is a plan view of the wall tie shown in Fig. 1.
Referring now to the drawings, the wall tie shown therein is formed from a strip of sheet metal in a single pressing operation. The wall tie comprises two end parts 10 and 11 which when viewed in plan are of generally rectangular shape, although the edges of the end parts each have a slight concavity to aid keying to the mortar. Each end part 10, 11 has a single mortar retaining generally rectangular dished depression 12, 1 3 respectively: more than one depression could however be formed in each end part and the depressions do not necessarily have to be generally rectangular.
The wall tie has an inverted channel section 14 which extends between the end parts 10 and 11. The section 14 has a downturned flange 1 5 along each of its opposed longitudinal edges. Midway between its ends the channel section has a raised preferably generally truncated pyramidical portion 1 6 with four inclined edges leading to deformations 1 7 in the flanges 1 5. The raised portion 1 6 is provided to discourage moisture and mortar collecting on the centre of the channel section 14 and the deformations 17, which are preferably in the form of laterally outwardly projecting pressed bulges, the lower edge of each of which is laterally outwardly displaced from the associated flange 15, are provided to shed moisture collecting on the raised portion 1 6.
The section 14 also has two upstanding pressed reinforcing elongate webs 18 and 19, one on either side of the raised portion 1 6.
The webs 1 8 and 1 9 extend in the direction of the longitudinal extent of the tie from the raised portion 1 6 to a position adjacent the corresponding end part 10, 11 and are provided midway between the two flanges 1 5.
The wall tie may be provided with a disc or plate shaped insulation locating member (not shown) snap-fittable on the channel section 14 between the laterally outward projecting pressed bulges 1 7 and being slideable therealong. The insulation locating member will be preferably of plastics material and will be capable of holding a sheet of insulation against one of the leaves of a cavity wall.
1. A wall tie pressed from sheet metal and having when viewed in plan two end parts, each having therein at least one depression and an inverted channel section between the end parts, the inverted channel section having a downturned flange along each of its two opposed longitudinal edges, a raised portion midway or substantially midway between its ends and two upstanding reinforcing elongate webs one on either side of the raised portion and extending in the direction of the longitudinal extent of the tie.
2. The wall tie of claim 1, wherein the raised portion is of generally truncated pyramidical shape.
3. The wall tie of claim 2, wherein the downturned flanges of the channel section have a deformation adjacent to the lower end of each inclined edge of the raised portion.
4. The wall tie of claim 3, wherein the deformations are in the form of outwardly projecting bulges.
5. The wall tie of any one of the preceding claims, wherein each end part is of generally rectangular shape when viewed in plan.
6. The wall tie of claim 5, wherein the edges of the end parts have a slight concavity.
7. The wall of claim 5 or claim 6, wherein each end part has a single generally rectangular depression.
8. The wall tie of any one of the preceding claims, formed in a single pressing operation.
9. A wall tie substantially as hereinbefore
