A connection system for providing a construction joint between a first concrete component and a second concrete component, the connection system comprising:
- a rebate former configured to form a rebate in the first concrete component, the rebate former including an elongated backing, the elongated backing including:
- an internal surface,
- an external surface, and
- folded edges to a predefined depth,
- wherein the rebate former is formed of sheet metal;
- a securing plug including an external thread;
- and
- an anchor including a body having a first end, a second end, and an internal thread,
- wherein the internal thread of the anchor is configured to mate with the external thread of the securing plug,
- wherein when the internal thread of the anchor mates with the external thread of the securing plug, the first end of the anchor engages the external surface of the elongated backing, and
- wherein securing plug is removable from the anchor after the first concrete component is formed, and thereafter a reinforcing bar is receivable in the anchor and configured to reinforce the second concrete component.
A method of providing a construction joint between a first concrete component and a second concrete component, the method comprising:
- providing a connection system including a rebate former configured to form a rebate in the first concrete component, wherein the rebate former is formed of sheet metal and, the rebate former includes an elongated backing, the elongated backing including an internal surface, and external surface, and folded edges to a predefined depth;
- providing a securing plug, the securing plug including an external thread;
- providing an anchors, wherein the anchor includes a body having a first end, a second end, and an internal thread;
- providing a reinforcing bar;
- mating the internal thread of the anchor with the external thread of the securing plug such that the first end of the anchor engages the external surface of the elongated backing;
- removing the securing plug from the anchor after the first concrete component is formed;
- and
- mating the reinforcing bars with the anchor to provide reinforcement for the second concrete component.
