BINDING WIRE FOR CONSTRUCTION

Galvanized, annealed galv. and black non galvanized binding wire are used for tying of steel bars in the concrete construction industry. It is also known as Construction Binding Wire. It is used for the purpose of tying applications in the field of construction. It is used extensively in the construction sector for tying the rebars at the junctions/joints so as to keep the structure intact. Binding wire is made of mild steel.

Binding wires are made from high quality carbon steel making them highly resistant to corrosion and abrasion. In RCC work where we use MS steel bars either plain or ribbed or tor, binding wires are used to bind the steel bars to each other at appropriate place according to design at a spacing defined by the drawing. The steel bars should not be disturbed while lying cements concrete in any of member such as column, beam, slab wall etc.

If the bars are disturbed than it will reduced the strength of RCC, so proper binding is necessary to intact the steel bars. Binding is usually done by hand with the help of hand tool but in heavy work big diameter steel bars some time bind with the help of welding.

Binding or fabrication of reinforcement shall be as per drawing and Bending shall be cold bending done either mechanically or with hand but to a correct radius with tools meant for the above work conform to IS 2502. Steel bars should be clear, free from loose mil scales, dust and loose rust coats of paints, oil or other coatings which may destroy or reduce bond strength. The bar is bent correctly and accurately to the size and shape as shown in drawings. The bar is bent correctly and accurately to the size and shape as shown in drawings. If possible, the bar of full length is used. Overlapping bars do not touch each other and these should be kept apart with concrete. The overlap if given should be staggered. The cranks in the bar at the end should be kept in position by using spots.

Binding wires is produced using top-notch carbon steel making them exceptionally impervious to consumption and scraped area. In RCC work where we use MS steel bars either plain or ribbed or tor binding wires are utilized to tie the steel bars to one another at proper spots as indicated by structure at a dividing characterized by the drawing. The steel bars ought not to be upset while lying concrete cement in any of the individuals, for example, segments, shafts, piece dividers and so forth.

The binding wire serves the reason for tying applications together in construction projects. It is particularly utilized for tying the Re-bars at the joints to keep the structure flawless. Binding wire is made of mild steel. The binding wire should be adaptable enough to be tied and furthermore sufficiently able to hold the joints. Binding wires are utilized to tie the steel bars. Other than evaluating the steel amount for various individuals, it is additionally critical to know the necessary measure of binding wires. Steel on call offers the binding wire that is useful in the construction field with variable costs, so as to make the construction solid and adaptable.

The tying applications in the construction field are utilized by the binding wire. It is utilized broadly in the development area for tying the rebars at the joints in order to keep the structure intact. Binding wire is likewise called annealed wire and is made of mild steel. Annealing enriches it with the properties like adaptability and delicate quality, required for its primary use. Binding wires are set up by the way toward strengthening which gives them adaptability, non-abrasiveness and required quality and strength. The diameters of the binding wire are ranging from 0.61 mm to 1.22 mm. The application of binding wire expects it to be adaptable enough to tie effectively and sufficient to hold the joint set up. There are different strategies utilized for tying the joints. Binding wire is utilized to hold the reinforcement at the proper position so that the bars don’t displace from their situation during the concrete, that is, they hold the reinforcing bars at correct dispersing positions in the construction.

Precaution while binding

The binding wire should be cut in to pieces from coil for binding.

Care should be taken that the length of wire should not be less than 4’’. Take 2 numbers wire and bind diagonally at joint tightly. Do not leave any joint, bind all the joints. At some places, there is a practice to bind alternately joints which is wrong practice and reinforcement may lose during laying RCC slab.

PURPOSE OF USING BINDING WIRE:

• To verify secondary things like chairs, spacer bars and so on in position during development, these binding wires are used.

• The binding wire holds the lapped bars in the perfect position.

• For various construction steel structures related purposes.

• Keep up the precise plan area, the direction of steel bars. To prevent dislocation of the steel bars when pouring cement on them; while combining the solid with vibrator and when laborers stroll over them.

The major purpose of binding wire is to keep the reinforcement free from any motion, because if it does move, then it can lead to changes in structural cross – sections and spacing within a structure. This can be detrimental to the strength of the structure and can also augment the probability of failure.

• The binding wires are used to hold the steel bars in place such that they do not exhibit motion when concrete is applied over them, or when the workers walk over them during construction.

• They hold the bars that are lapped in an ideal position.

• They are also useful in securing the secondary attachment like spacer bars into a rigid position.
