In order to provide the required rigidity and strength of a reinforced concrete structure, it is necessary to bind reinforcement. Of course, the method of attaching the reinforcement and its fixation also play a big role, so quality control must be present at all stages of the manufacture of the product. A modern rebar tying gun meets all the requirements for it and makes reinforced concrete products strong and durable. Let's talk about how to choose the right knitting gun and what it should be.
Is mating required?
Many might think that this event is not nearly as necessary as they say. After all, where can the reinforcement fixed in concrete go. In addition, there are a large number of other methods, such as spot weldingor plastic clamps. However, they all have significant drawbacks. Something is extremely unstable to active dynamic loads, while other connecting elements fail under the influence of vibration. As for knitting with flexible wire, this method is considered the most time-consuming and at the same time effective. In places of knitting, corrosion does not appear, and high strength is achieved due to the high tensile strength and plasticity of the binder, that is, the wire. For this simple reason, it makes sense to purchase a special gun that will make the work faster and more automated.
Rebar tying tool
It is quite logical to ask yourself the question: how to do the work? Naturally, a certain tool is required. As noted above, this may be a pistol operating in automatic mode. However, the purchase is not cheap, so for small amounts of work it is advisable to use a regular hook or tongs. For example, the most elementary hook can be made from an ordinary nail, and pliers can be found in the garage or bought in a store for fabulous money. But all this is effective only for the time being. If you are building a bathhouse and a garage for yourself, then such a tool will be very useful, but when building larger structures, professionals advise buying screw hooks and automatic pistols. This will make the work performed easier.
Automatic rebar tying hook
The hook can be automatic or manual. For large volumesworks it is desirable to use the second option. The fact is that the rotation of the hook is carried out by the translational movements of the handle. At the same time, to ensure the connection with a simple hook, it is necessary to apply great efforts, which takes a little more time and effort. But if a manual hook costs only 300-400 rubles, then an automatic hook costs about 350-500 rubles. In principle, the difference is insignificant, but with a large number of connections, you will realize that working in semi-automatic mode is much easier and better. In addition, such a tool has another significant advantage - reliability. Agree, it will not be very pleasant if the product breaks on the first connection. For this simple reason, pay attention to the quality of the product, its strength and brand. But there is an alternative way out, now we will consider it.
How to choose rebar pliers
One can say that hooks, even automatic ones, are gradually fading into the background. At the same time, pliers for knitting reinforcement are becoming more and more popular. This is due to the fact that such a product does not produce waste during the execution of work and allows you to cut the wire from a roll and immediately create a connection. For greater durability, the cutting edges are hardened. Typically, the working range ends at a wire diameter of 3.1 mm, although there are exceptions, which completely depends on the manufacturer. Many even say that pliers are better than a knitting gun. This is due to the fact that they are more reliable and do not depend on the battery or the network. But this argument is debatable. In any case, it is better to use a pistol, but have pliers in your pocket, which will help out in case of emergency.
For professionals - a knitting gun
If you need to quickly and efficiently erect a large object from monolithic concrete, then pliers and hooks are ineffective. A special pistol is best. It can work both from the accumulator, and directly from a network. Visually, the tool resembles a screwdriver. The fundamental differences are that there is a built-in microchip responsible for the tension of the wire, and a drum on which the binder is wound. Do not forget that this is a very expensive equipment, so it is advisable to buy it for large volumes of work. The price for the simplest models starts at 20,000 rubles, and the best options will cost about 100,000 rubles. In most cases, it makes no sense to purchase units that are too expensive, but a lot depends on which manufacturer you prefer. First, let's talk about what features to look out for, and then look at a few popular manufacturers. In any scenario, the choice must be approached carefully and responsibly, paying attention to the smallest details.
Diameter of reinforcing bars and wires
It is extremely important to pay attention to these two parameters. For example, the diameter of the reinforcing bars with which the Japanese Max pistol works is divided into three groups: 9-21, 20-39, 32-51 mm. But the manufacturer MAX also has universal models,in particular, RB397, which is able to work both with a monolithic foundation and with the formation of a floor. However, equipment operating in such a wide range is not cheap, about 100 thousand rubles. Sometimes a tying gun is enough, which can work with wire with a diameter of 9 to 39 mm.
Another important point is the diameter of the wire. If you are going to use 1 mm wire, then the knitting gun must be selected based on this. To date, wire from 0.8 to 1.5 mm is most often used, therefore, appropriate knitting equipment is produced. For example, the same rebar tying gun Max of the DZ-04-A01 model range, worth 33 thousand rubles, is ideal for such work. In addition, there are complete sets with additional adapters and a rechargeable battery.
Speed of work and type of food
To maximize productivity, you need to pay attention to the speed that the knitting gun develops. Most modern models process one connection in no more than 1.4 seconds. In priority, it should be 1.1 seconds. However, Max's XDL-40 knits the joint in 0.8 seconds. Even with such a slight difference, performance increases significantly. In about an hour, you can create about a thousand connections, but in practice it always turns out a little less, which depends on the operator. The cost of such a pistol is about 39 thousand, but its scope is very wide. It can be used asconstruction of airfields and residential buildings.
It is extremely important to pay attention to the type of food. Since it is far from always possible to connect to the network at a construction site, the option of working from a rechargeable battery looks more profitable. Usually two batteries are included in the package. While working with one, the second can stand on charge. If you buy an inexpensive gun for work at home, then it can also be powered from the mains. There are also mechanical devices that are completely energy independent.
Wacker binder guns
Today, there are several competing companies that lead the world in the manufacture of high quality rebar guns. One such firm is Wacker. This is a very famous brand all over the world. Equipment at a high cost has excellent performance characteristics. For example, a mechanical model DF-16 WN will cost 90 thousand rubles, but in return you will receive an indispensable assistant. The time per knot is 0.8 seconds, and the staple thickness is 1.1 mm. This unit can work with fittings from 6 to 16 mm, and all this with a mass of only 2.2 kilograms. In any case, if you appreciate the reliability of the tool, then the Wacker rebar tying gun is your choice.
Equipment Reviews
Before buying, always pay attention to what buyers write. Sometimes it happens that a seemingly good model from a well-known manufacturer, but has negative feedback. Sometimes there are minor flaws, but it also happens that ergonomicsdevice is not well made. This, in turn, complicates the work performed, since it is inconvenient to hold the tool, as a result of which the hand gets tired quickly. For example, MAX and Wacker have practically no dissatisfied customers, so it is recommended to buy a rebar tying gun from these companies. Reviews say that the equipment lasts a very long time, and the build quality is on top. In any case, do not forget to visit several thematic forums before buying.
Conclusion
So we talked with you about what a knitting gun is and what it is for. It is worth repeating once again that you need to buy only from a trusted company. Moreover, pay attention to consumer feedback and expert advice. Sometimes it's not so important that the gun creates a connection in 0.8, and not in one second. At the same time, the price will already differ by several thousand rubles. In addition, you should buy a gun only when you really need it. If you are a professional builder, then it will come in handy, but if you are doing it at an amateur level, then it is better to buy quality pliers or an automatic hook. In principle, this is all that can be said about the choice of a knitting tool for construction work. Remember: you are dealing with concrete products, so the connections must be reliable and of high quality, then they are not afraid of vibrations and dynamic loads.
