The 2 Most Important Things When It Comes To Tying Rebar

Concrete has seen many applications in the construction industry, from comprising the walls of modern residences to being used to make the curbs or pavements that line our neighbourhoods. It’s generally safe to say that wherever there is concrete, there is rebar to reinforce it and preserve the material’s structural integrity.

You could do a lot of things with rebar in order to fulfil your structural reinforcement needs. Most commonly, you’ll see construction workers cutting and bending rebar for various tasks using specialized cutters or rebar benders, respectively. Similarly you could also tie rebar to achieve greater sturdiness in your structure and that is what this article focuses on.

It doesn’t matter if you’re a steel installer or just someone who’s overseeing the construction of your own home. It’s good to know the two most important things when it comes to tying rebar properly:

Purchase the Right Shape Of Rebar

The shape of rebar to be used is could differ from one project to the other. This might involve some hunting. While you could use any regular rebar for the typical foundation-building or slab reinforcement, specialized, more complex projects like supporting walking steps, could demand specifically-shaped ones. Here are a few examples of rebar shapes:

  • Dowels – these are straight, followed by a right angled bend on one end.
  • Hairpins – these are shaped like a horse shoe and therefore can be interlocked to increase the lateral strength of the structure that is being reinforced.
  • Candy canes – as their name suggests, these types of rebar are shaped like candy canes and like hairpins, they too can be interlocked to provide strength to a structure.
  • Corner bars – these are similar to dowels, except that the straight portion and the bent portion are the exact same length.

Decide On the Right Tie

When you’re trying to decide on the right tie to use, consider the amount of force that’s going to be placed on the rebar during the concrete placement. For instance, if you’re dealing with slab mats that won’t subject the rebar to a lot of pressure during placement nor cause them to move from their original positions, you could use a simple snap ties to bind the rebar together. In cases where concrete placement will result in some displacement of rebars, it is best to go for more complex ties.

The following are some of the different types of ties available and their applications:

  • Snap tie – as mentioned above, they’re a simple solution for simple situations. This is achieved by securing rebar together by merely wrapping thin wires around them. They’re typically used for horizontal surfaces.
  • Saddle tie – a complicated ‘U’-shaped tie and is often used for vertical structures such as walls.
  • Figure 8 ties – they are similar to saddle ties, involving quite a few steps that are bit hard to master. Figure 8 ties are typically used when you need to prevent diagonal movement between rebar that are at right angles with each other.
  • Wrap and snap – used to tie horizontal and vertical rebar together in such a fashion that there is no sliding as a result.

Tying rebar is an extremely important process that also happens to be a bit complicated. Therefore, we recommend that you reread this article every time you have to deal with the process.
