Can plastic zip ties be used to join rebar?
Yup, the local HfH chapter uses plastic zip ties in a design provided by the ICF manufacturer to tie the rebar to the plastic ribs built into the ICF forms. Personally, since my hands are large enough for getting into the tighter places---it requires both hands to apply the zip ties----I think is is a pain. But, it is code compliant.
What is the difference between rebar and steel?
- Steel is ductile material whereas concrete is brittle material.
- Steel has high tensile strength and concrete has high compressive strength.
- Concrete structures can undergo sudden failure as it will be brittle failure whereas steel structures don't undergo sudden failure as they show signs of failure in advance.
Is tying rebar necessary?
Ideally, every intersection of the rebar has to be tied for maximum support. The ties do not actually make the structure strong. They prevent the rebars from getting displaced when the concrete is being poured. The tie wires should be placed at the right depth from the surface so that the rebar does not rust.

How often does rebar need to be tied?
A rebar mat tied 20% would generally entail ties 100% around the perimeter and every 5th intersection everywhere else where the ties are staggered so that in every direction, there is always a tie on at least every 5th intersection.
What are #3 rebar ties?
The rebar 3-rod metal basket is a durable rebar support system that is ideal for concrete applications. The chair is designed to hold up to 3 pieces of rebar and allows the rebar to sit above the ground while concrete is poured. Rebar ties are needed to secure rebar to basket to ensure rebar stays in place.
Is tying rebar hard work?
Physical Strength and Stamina: The job requires carrying heavy loads and spending many hours standing, as well as bending and stooping as workers install rebar. Hand-Eye Coordination: Workers must be able to tie rebar together quickly, as construction usually is very fast-paced.
Can you weld rebar instead of tying?
Weld-able Rebar This grade of rebar has a steel-to-carbon ratio that makes it suitable to be welded. Not only is it suitable for welding, but the welds can stay together under significant load after it has been sealed in concrete.
How far should rebar be placed from edge of concrete?
For welded wire reinforcement, the Wire Reinforcement Institute recommends steel placement 2 inches below the surface or within the upper third of the slab thickness, whichever is closer to the surface.
How far apart do you put rebar in concrete?
Place rebar in a grid pattern with a spacing between bars of approximately 12 inches. In either case, blocks should be used under the reinforcement to keep centered within the concrete.
What are rebar ties made of?
Rebar tie wire, also known as rebar tying wire, is made from the softest low carbon annealed steel wire. With fully galvanized and PVC coating on the surface, it offers excellent flexibility and corrosion resistance mainly used for tying and bundling reinforcing steel bar, supporting plants in gardens.
What gauge is rebar tie wire?
340 ft. 16 Gauge Rebar Tie Wire lets you easily secure a rebar in place or tie several rebars together before you pour concrete. Its pliable annealed design ensures a snug and secure tie. This is also a great multi-purpose wire that can be used for all types of repairs and projects.
How to tighten rebar ties?
Pliers. In a pinch, you may be able to use pliers to tighten down your rebar ties, as well. This can be done after manually wrapping your rebar rods as desired. Then, with the two resulting loose ends, you can pinch them with the plier and begin twisting. This can add proper tension to the joint.
How to tie rebar by hand?
How to Tie Rebars: A Step-by-Step Guide. In order to tie rebar by hand, you’ll need to learn the proper technique for application. To do this, you’ll first want to secure a twister tool as well as a proper gauge of rebar tie wire. Once you’ve done that, you’ll want to wrap your rebar using one of the patterns outlined above.
What is a wrap and snap tie?
As their name suggests, a wrap and snap tie is a hybrid tie that combines the supportive elements of both the snap and saddle ties. In practice, this takes the form of a tie that is diagonally tied around one strand and then horizontally around both at once.
How do saddle ties work?
Specifically, saddle ties are applied by threading a rebar tie wire above and below the rods at a cross point. This creates a saddle-like form that secures the rods in two directions.
What is a snap tye?
Snap ties are the first and most common type of “knot” used to secure rebar rods together. They’re used most often because they can be placed and tied off manually, as well as with a rebar tying tool.
What is a rebar tying tool?
When someone asks you for a “rebar tying tool,” they’re typically referring to a streamlined hand tool (like the Makita XRT01TK) that looks a bit like an electric drill. However, instead of an end-mounted chuck, a rebar tying tool features a claw-like end piece from which rebar tying material is extruded.
Can you use a saddle tie to tie rebar?
While applying a saddle tie is fairly straight forward, it can be challenging to accomplish by hand. As such, a rebar tying tool is recommended for applying this type of tie. If one is used, you can create effective diagonal bonds between rebar rods in most vertical or horizontal structures.
What is a tie for rebar?
This is a simple type of tie. The wire is wrapped once, diagonally over the junctions of rebars that should be tied, and twisted several times to create a knot. These types of ties can be used when the rebar is in the horizontal position. They are also named as single ties.
What is a cross tie?
Cross tie : This type of tie is also called a figure-eight tie as it resembles the number eight. Half a round of the wire is run beneath the bottom bar on either side and wrapped diagonally over the top bar to tie a knot. All these types of ties are used depending upon the nature of work, rebar position, type of structural member, etc.
What is binding wire?
The binding wire is wrapped to make a one and half-round alongside the top bar instead of half-round as in the case of saddle tie. This extra grip retains the bar movement from its tied position.
Why is the binding wire wrapped with a double strand?
Instead of a single strand as in the case of a snap tie, here, the binding wire is wrapped with a double strand to make it stronger and more secure.
