EDGE PROTECTION SYSTEM - FLOATING COVER PLATE ON INTERSECTION
An edge protection system including a first expandable armoured joint to protect a first joint extending in a first direction, a second expandable armoured joint to protect a second joint extending in a second direction and an intersection module including a cover plate located at an intersection of the first expandable armoured joint and the second expandable armoured joint.
AN EDGE PROTECTOR ADAPTED TO BE CAST INTO THE EDGE OF A CONCRETE FLOOR SLAB
Edge protectors are useful to be cast into the edges of concrete slabs to prevent spalling thereof after shrinkage has occurred and a gap has formed between adjacent slabs. An alternative edge protector (10) is described which comprises a first folded sheet having, in use, an upper (35) and a lower portion (25), the fold being on a first side of the first folded sheet and being alignable, in use, with the sidewall of the slab, the upper portion being planar and being arrangeable, in use, with its upper surface coplanar with the upper surface of the slab, the lower portion extending at least partially under the upper portion in a direction away from the fold, and continuing from the end of the lower portion in the same general direction, without any further folds or bends greater than 90 degrees, as an anchor portion (20) such that the anchor portion is arrangeable within the slab.
CONCRETE DOWEL PLACEMENT SYSTEM AND METHOD OF MAKING THE SAME
A concrete dowel placement system and methods for making the same. The system allows for accurate and easy substantially-parallel or parallel placement of slip dowels within sections of concrete so that adjacent sections of concrete may be allowed to undergo thermal expansion and contraction while remaining in a common plane without cracking or faulting. The system includes a coupler and a sheath. The sheath is configured to be slidably extensible over the coupler and may be held to the coupler by friction. An outer surface of the sheath may be textured. Additionally, a method of constructing the concrete dowel placement system includes extruding material to form two tubes of different sizes. The tubes are then attached to each other, then material is extruded or injection molded to form a sheath. Alternatively, construction may include extruding material to form a tube, then removing some of the material from the tube in order to form a coupler.

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.
ARMOURED JOINT - ANTI-SKEW STAKE BRACKET
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 to the first component and a second anchorage part for anchoring to 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 edge, the second plate defining a second edge, wherein the first edge and the second edge are shaped to facilitate bringing together of the first edge and the second edge, and wherein the second anchorage part is adapted to be movable relative to the first anchorage part from a close configuration in which the second edge is brought together with the first edge to a spaced configuration in which the second edge is spaced relative to the first edge, wherein the first anchorage part or the second anchorage part has a support section, the armoured joint including a bracket for supporting the armoured joint relative to a ground surface, the bracket comprising an angled upper leg and an angled lower leg, wherein the bracket is fixed to the support section by the angled upper leg and the angled lower leg, the angled upper leg being fixed to the support section to extend downwardly from the support section at a first angle and the angled lower leg being fixed to the support section to extend upwardly from the support section at a second angle of the same magnitude as the first angle.
