How far apart do you tie rebar?

The publication states in bold: “It is not necessary to tie reinforcing bars at every intersection. Tying adds nothing to the strength of the finished structure”. CRSI further states that in most cases, tying every fourth or fifth intersection is sufficient. The publication includes three examples as shown below.

How do you calculate rebar ties?

Estimate Binding Wires for Tying Rebars

1. We use binding wires to tie the rebars.
2. For rebar tie wire estimate apply thumb rules,
3. Binding wires needed for 1 quintal (100 kg) of steel reinforcement = 0.9 to 1.3 kg.
4. Binding wires needed for 1 ton (1000 kg) of steel reinforcement = 9 to 13 kg.

Do you have to tie rebar together?

Question: When reinforcing concrete, is it necessary for rebar to be tied together? Explanation: You need to tie the rebar together so that it does not shif or move during placement of the concrete.

Can I use zip ties for rebar?

rebar shall be allowed to be bonded together by the usual steel tie wires or other effective means. Unless you can get an inspector to agree that zip ties are an “effective means” it is not code compliant.

What should splice and lap lengths be for galvanized rebar?

In particular, splice and lap lengths are the same as for black steel bar, as are bond and load transfer considerations. Best when utilizing galvanized reinforcement is to use appropriately designed and placed concrete as would normally be used in general reinforced concrete construction.

Do you have to tie reinforcing bars at every intersection?

General Principles of Tying Reinforcing Bars Strange as it may seem, the ASCC Hotline still gets calls from contractors who ask for assistance in educating an inspector who says all reinforcing bars must be tied at every intersection.

What kind of tie to use on wall reinforcing bars?

When assembling wall reinforcing bars in place, the spacing of ties should be sufficient to prevent shifting of the bars as concrete is being placed. CRSI recommends that a snap or snap and wrap tie is generally used, but in most cases the snap tie is adequate. The example below shows ties at every third intersection, each way. Preassembled Mats

What kind of wire do you use to galvanize a bar?

Any touch-up is minimal and usually caught before a bar is installed. Galvanized tie wire or plastic clips should be used when assembling or installing galvanized bar, and bar supports also should be galvanized steel, plastic, or some other inert material such as masonry. If mechanical couplers are being used, they should be galvanized as well.
