![]() It can also be done easily with a pair of 9 inch (22.9 cm) lineman's pliers and bulk wire held on the rodbuster's workbelt in a wire reel. ![]() This tie is known as a snap tie, and can be made with the snap tie precut ties and a spinner, noted earlier. For ordinary slab mats, where the force of the concrete interacting with the rebar during its placement is minimal, and movement of the mats is unlikely, using a simple, single twist of wire around each rebar intersection, twisted together tightly, will suffice. For the bag ties ( Snap Ties, not to be confused with the snap ties described later). Select the appropriate type of tie you will use. Candy canes - As the name implies, these are straight lengths of rebar with a U shaped bend on one or both ends, again to interlock two or more parallel reinforcing mats.Hairpins - These are U shaped rebar that are often used to interlock two or more individual mats of rebar to give lateral strength to the concrete casting.Offset bends - These range from a simple Z shape to complex angles, used in reinforcing concrete walkway steps and steps (changes in elevation) in concrete footings.Corner bars - These are also L shapes, with each side of the ell the same length.Dowels - These are usually L shapes, or straight lengths of rebar with a ninety degree bend on one end.They create a framework that keeps these larger bars in position, and may be round, square, rectangular, or even complex combinations of shapes. Stirrups - These are shaped rebar that hold the lateral reinforcement in a certain configuration, often called a cage.For complicated applications such as grade beams, foundation walls, tanks, and other projects, you will need to have specific shapes formed by a rebar fabrication specialist. For simple projects like typical building foundations and slab reinforcement, you can most likely buy the necessary rebar from a building supply center or home improvement warehouse.
