Reinforcing bar steel or rebar is an essential component of any construction project. Rebar enhances the strength and longevity of concrete and rebar tie wire is used to tie the reinforcing bar steel together. Rebar tie wire is strong and durable and can hold the steel bars in place until concrete is poured onto it. Tying the rebar manually requires a lot of time and human resources on the other hand rebar tie wire reel and gun make the process faster and easier.
If you are a construction worker or a contractor who regularly has to use rebar tie wire to secure steel bars then using the tie wire reel and gun is an essential tool for you. A lot of construction sites are already replacing manual rebar tying methods with automated rebar tie wire reel and gun methods. If you want to learn more about rebar tie wire reel and gun then this article explains everything you need to know about this great tool.
1. What is a Rebar Tie Wire Reel and Gun?
Rebar ties wire reel and the gun is the name given to the combination of a specialized gun tool that holds a reel of rebar tie wire. When this gun is operated it automatically ties the tie wire around the intersection of rebar and then twists it to secure the two steel bars. Since rebar tie wire is responsible for holding the steel bars that provide foundational support to the structure, securing the rebar is an essential part of any construction project. A rebar wire tying gun ensures that the rebars are firmly secured and don't develop gaps during the concrete pouring process.
The tie wire is fed into the gun in the form of a reel that allows the mechanism inside the gun to use the right amount of wire for each tie. Not to mention using a tie wire reel and gun gets consistent ties each time instead of pliers and cutters.
2. What Is The Internal Working Mechanism Of A Rebar Tie Wire Reel And Gun?
Rebar tie wire reel and gun is easy to operate and there is little to no learning curve for using this tool to tie down rebar. The working mechanism of the rebar tie wire reel and gun is also simple yet precise. Here is how this efficient tool works:
2.1 Installing a full rebar tie wire reel into the gun
Before a worker starts using the gun it requires a full rebar tie wire reel. The reel comes with specialized holes on the sides that allow the reel to be rotated inside the rebar tie wire reel compartment of the gun. The wire comes in different gauges which determine the diameter of the rebar tie wire. Depending upon the length of the wire you can use a single rebar wire reel to tie up to 200 knots or more.
2.2 Positioning the gun in the intersection
The front of the tie-wire gun is responsible for dispensing and twisting the wire around the intersection. So the operator has to position the gun precisely on the intersection of the rebar to get a good knot. Luckily there are two curl guides at the front of the rebar tie wire reel gun that allow users to tie the knot precisely.
2.3 Trigger mechanism
Since modern rebar tie wire guns are battery operated they come with a trigger similar to a drill that can be pressed to tie two rebar together. The rebar wire tying gun wraps the wire around the two steel bars in a circular motion making sure that both the bars get joined together.
2.4 Twisting mechanism
This is the most crucial step in the operation of a rebar tie wire gun because it twists the rebar tie wire together resulting in a lasting knot. The gun has a built-in twisting mechanism that engages at this step. It grabs the two ends of the wire and twists them around each other similar to how a worker would do with pliers. A twisting mechanism is designed to rotate a certain number of times which is enough to lock the rebar in place.
2.5 Cutting the wire
Once the rebar tie wire has been twisted together, it must be cut at the end of the knot. This is also done through the inbuilt cutter inside the gun that ensures a clean cut reducing wastage of the tie wire.
A high-quality rebar tying gun can do the work for multiple workers on a single charge and the results are consistent from one knot to the next. While the working mechanics of a rebar tying machine may seem simple there are multiple different mechanisms inside the machine that work together to create ties. Not to mention the process of putting the tie wire around the rebar, then twisting and cutting the wire happens almost instantly. So the workers can quickly move from one knot to the next.
3. What Are The Different Types Of Rebar-tying Tools?
Rebar tying tools come in two major forms one that are fully automatic battery operated tool offered by Great Magtech and the manual tools that require human involvement. Both types of rebar-tying tools have their distinct operation and offer different levels of efficiency. Without further ado here are the two major types of rebar-tying tools and how they differ:
3.1 Manual rebar tie wire tools
A manual rebar tie wire tool has a mechanism that can be used to twist and turn the tie wire around the rebar. While it comes with a twisting mechanism that makes the process of twisting the tie wire easier it doesn't have a circulating or cutting mechanism for the wire. So the worker still has to do most of the work when tying rebar wire using a manual rebar tying tool.
3.2 Automatic rebar tying tool
Automatic rebar tying tools take care of everything from rotating, twisting, and cutting action involved in the process of securing two rebar. As explained in the previous section automatic rebar tying tools are battery operated that need a tie wire reel to be installed in it.
There is zero manual effort involved in using automatic rebar-tying tools. All you need to do is position the automatic gun-shaped tie-wire tool in the cross-section of two rebars and squeeze the trigger. The tool will tie, twist, and cut the tie wire almost instantly so you can move on to the next knot.
4. Why Should You Use Rebar Tie Wire Reel And Gun Combination?
As explained above modern gun-shaped rebar-tying machines are much more efficient and easier to operate. However, these machines offer much more than just efficiency, and here are some major reasons why you should use rebar tie wire reel and gun instead:
4.1 Reduced labor cost
While manually tying up the rebar wire requires a large number of workers who will need pliers and cutters automatic rebar tying machines allow fewer employees to perform the same amount of work. So not only will you have to pay fewer employees to complete a rebar tying project but you will also save up on multiple pliers and cutting tools.
4.2 Improved safety
Safety at the construction site is a major concern for contractors. Since the manual rebar tying process requires the use of pliers and cutters not to mention it is a repetitive process it can result in injury for workers. Automated rebar-tying guns eliminate the risk of injury caused by repetitive tasks.
4.3 Versatility
When you invest in a high-quality rebar-trying gun you can use it for various types of rebar assembly applications. These machines are ideal for use in both large-scale commercial buildings and residential units. So a single rebar tying machine is going to serve you for years to come no matter what type of construction projects you work on.
5. What Are Some Applications Of Rebar-tying Machines?
Rebar tying machines are designed to be used for securing rebar in a wide range of construction-related applications. Here are some of the most popular areas of construction where rebar-tying machines are used:
5.1 Construction of concrete slabs
The most common application of rebar tying gun and tie wire is in the assembling process of rebar grids for building foundations. Concrete slabs require rebar as a central reinforcing structure and a rebar-tying gun is essential for tying the rebar together.
5.2 Beams and Columns
Beams and columns are vertical and horizontal reinforcement structures of a building. Similar to concrete slabs beams and columns also need rebar tie wire to assemble the steel structure. The rebar tying gun makes the beams and columns assembly faster and ensures that the central steel structure remains intact during the concrete pouring process.
5.3 Building infrastructure
Everything from roads and bridges to tunnels needs steel meshes to provide the rigidity and strength needed to meet the highest possible standards of construction. Since the length and width of steel meshes used in roads and bridges are much bigger than in building construction ensuring that each rebar bar is secured in place is essential for the strength of the structure.
Tie wire gun allows for uniform mesh grid assembly and reduces the risk of error.
5.4 Precast concrete elements
Precast concrete elements are structures such as walls and beams that are poured and cured in a factory and transported to the construction site to be fixed in their place. Precast concrete elements also use rebar that needs to be tried together using a rebar tie wire gun to ensure fast rebar assembly and production.
6. Difference Between Manual Tying And Machine Tying
Manual rebar tying and machine tying both have their usage depending upon the scenario or the scope of work. Here are the major differences between manual tying and machine tying:
