How to Tie a Rebars

 

Building construction begins after the completion of the documentation process. And construction involves forming, grading, placing, and finishing. One critical step is placing the reinforcing bars correctly. There are various types of tying techniques and tools used to do the trick. In today’s blog, we will discuss the different techniques of tying rebars.

The General principles of bar tying

Rebars are tied to an intersection in order to maintain during work performed by other trades and during concrete placement. it’s not necessary to tie rebars at every intersection and doesn’t increase the strength to the finished construction. In most cases, rebars are tied at a pattern as the specification requires. Only coated tie wires are used to tie coated bars. The various types of tying techniques used to secure reinforcing rebars are illustrated in the Concrete Reinforcing Steel Institute (CRSI) publication.  Placing reinforcing bars is explained in chapter 10 of the publications. In today’s blog, we like to share some of the lists in today’s blog.

Snap or single tie is the most common and simplest type of tie that is extensively used in flat horizontal work to secure the reinforcing bars in position against displacement due to work done by other trades and by concrete placing. it is wrapped once around the two crossing bars in a diagonal manner with the two-wire ends on top. The wires are then twisted together with a pair of pliers until they are tight against the bars. The wire is cut and the ends flattened to stop them from snagging clothing or protruding through the concrete surfaces.

The wrap and saddle tie is similar to the saddle tie except that the wire is wrapped 11 ⁄2 times around the first bar, then completed as described for the saddle tie. This type can be used to secure heavy mats that are lifted by crane and for securing column ties to vertical bars where there is a considerable strain on the ties.

saddle or “U” tie is more complicated than mentioned in the first two but is preferred in some regions. It is used to tie foot bars or other mats to keep the hooked bar ends in position; It is also used to secure vertical bar column links. The wires move halfway around one of the bars on either side of the bar, then squarely around the bar and up and during concrete placing.

When you are tying rebars the spacing you choose is governed by the size of the rebar. And wall bars that are assembled in place should be tied sufficiently to prevent shifting as concrete is being placed. The snap tie or wrap and snap tie is generally used, but in most cases the snap tie is adequate. In our previous blog, we have covered some of the useful tools that are used in tying rebars.
