Armoured joint-disruptive folded anchor rail
An armoured joint for protecting an edge of a first component formed of settable material and an edge of a second component formed of settable material at a joint, wherein the apparatus includes a first anchorage part for anchoring within the first component and a second anchorage part for anchoring within the second component, a first plate coupled to the first anchorage part, a second plate coupled to the second anchorage part, the first plate defining a first abutment surface, the second plate defining a second abutment surface, wherein the first abutment surface and the second abutment surface are shaped to facilitate abutment of at least a portion of the second abutment surface against the first abutment surface, and wherein the second anchorage part is adapted to be movable relative to the first anchorage part from an abutting configuration in which at least a portion of the second abutment surface is in abutment with the first abutment surface to a spaced configuration in which the second abutment surface is spaced relative to the first abutment surface, wherein the first anchorage part includes an elongated angled anchorage lacer bar, the elongated angled anchorage lacer bar being supported by a series of spaced ribs and the rail being tilted out of the plane of the ribs.
1 . An armoured joint for protecting an edge of a first component formed of settable material and an edge of a second component formed of settable material at a joint, the armoured joint comprising:
a first plate including a bottom surface and a first abutment surface;
a first anchorage part configured to be anchored within the first component, the first anchorage part including a first elongated angled anchorage lacer bar, the first elongated angled anchorage lacer bar being supported by a series of spaced first ribs and a first rail being tilted out of a first plane of the first ribs such that the first rail extends vertically downward relative to the bottom surface of the first plate,
wherein the first plate is coupled to the first anchorage part;
a second anchorage part configured to be anchored within the second component; and
a second plate coupled to the second anchorage part, the second plate including a second abutment surface,
wherein the first abutment surface and the second abutment surface are shaped to facilitate abutment of a portion of the second abutment surface against the first abutment surface, and
wherein the second anchorage part is movable relative to the first anchorage part from an abutting configuration in which the portion of the second abutment surface is in abutment with the first abutment surface to a spaced configuration in which the second abutment surface is spaced relative to the first abutment surface.
2 . The armoured joint of claim 1 , wherein the first elongated angled anchorage lacer bar is substantially perpendicular to the first plate.
3 . The armoured joint of claim 1 , wherein the second anchorage part has a second elongated angled anchorage lacer bar, the second elongated angled anchorage lacer bar being supported by a series of spaced second ribs and a second rail being tilted out of a second plane of the second ribs.
4 . The armoured joint of claim 1 , wherein the armoured joint includes at least one dowel configured to maintain a level of the second anchorage part relative to the first anchorage part.
5 . The armoured joint of claim 1 , wherein the first elongated angled anchorage lacer bar varies in width between at least two of the series of the first ribs.
6 . The armoured joint of claim 1 , wherein each of the spaced first ribs has a tapered foot that tapers outwardly into the first elongated anchorage angled lacer bar.
7 . The armoured joint of claim 6 , wherein each tapered foot progressively tapers outwardly into the first elongated angled anchorage lacer bar.
8 . The armoured joint of claim 6 , wherein each first rib is bent at the tapered foot such that the first elongated angled anchorage lacer bar is tilted out of the first plane of the first ribs.
9 . The armoured joint of claim 1 , wherein each of the first ribs is angled at an acute angle relative to the first plate, and the first elongated angled anchorage lacer bar is tilted to be substantially perpendicular to the first plate.
10 . The armoured joint of claim 1 , wherein, between each pair of successive first ribs, an upper edge of the first elongated angled anchorage lacer bar is tapered progressively outwardly then progressively inwardly.
11 . The armoured joint of claim 1 , wherein, between each pair of successive first ribs, an upper edge of the first elongated angled anchorage lacer bar has a generally wave-like form.
12 . The armoured joint of claim 11 , wherein, between each pair of successive first ribs, the upper edge of the first elongated angled anchorage lacer bar has a single wave form.
13 . The armoured joint of claim 1 , wherein the first elongated angled anchorage lacer bar is in the form of a part of sheet metal.
14 . The armoured joint of claim 1 , wherein the first anchorage part includes a support surface extending substantially parallel to the second plate and configured to support the second plate.
