Reinforced concrete structures are increasingly used in modern urban construction, especially in bridges and steel-concrete buildings. However, as time goes by, concrete buildings need to be demolished due to various reasons. The concrete itself is very hard, and the interior is still There are steel bars, if common wall saws or drilling rigs are used to demolish, it takes time and effort, and diamond wire saws are used to demolish steel-concrete buildings, but what kind of steel-concrete wire saws are used to cut various types of steel-concrete buildings? What about hard reinforced concrete buildings?

Steel-concrete construction cutting is an industrialized operation. Since it is an industrialized operation, the pursuit of high cost performance is the clearest goal. How to choose a wire saw product with higher cost performance, how to make steel-concrete construction cutting faster, and how to make steel-concrete construction Is the cutting of objects more in line with people's needs?

The hardness and strength of concrete determine the choice of wire saw

The hardness of concrete refers to the degree of difficulty of concrete in the cutting process. The higher the hardness, the more difficult it is to cut concrete, but it is not the concrete with high strength that is the concrete with firm structure. In fact, the strength is the parameter that determines the degree of concrete construction, and the strength determines Whether the concrete will deform and break is determined according to the yield strength and tensile strength of the concrete. To put it simply, concrete with high hardness and low strength is more common in tofu dregs projects and is also the main target of concrete building demolition. With high strength, the hardness of concrete may not necessarily be high, which depends on the ratio of cement to sand and gravel used by people.



The higher the hardness of the concrete material, the higher the cutting hardness of the required design wire saw. In the choice of beats rope diameter, 11.5mm and 12mm steel-concrete wire saws are more commonly used. In terms of hardness, low-cobalt-based and iron-based wire saw beats matrix will be better. In terms of diamond grade selection, the higher the grade, the better the grinding effect on hard concrete. The highest concrete hardness can reach a Mohs hardness of 9, which is only 10 milliseconds from the hardness of diamond, so it is very necessary to choose a higher grade diamond. However, among the common C20, C25, and C30 concretes, the concrete material is mainly pebbles. The Mohs hardness of this concrete material is about 6.5. For such soft concrete materials, it is suitable for lower grade diamonds.

In terms of strength, the higher the concrete strength, the greater the amount of cement used. Although it is not that the higher the hardness of the concrete, the better the strength, but the higher the strength of the concrete, the greater the hardness (caused by more cement components). Therefore, when choosing a diamond wire saw, you must consider the hardness of the carcass and the grade of the diamond. For the specific selection method, please refer to the previous paragraph.

The thickness of the steel bars also determines the choice of wire saw

Reinforcing steel bars are necessary in steel-concrete buildings. The steel bars inserted in the concrete increase the shock absorption and seismic strength of the building. Especially in the beam structure of the building, the thicker the steel bar, the stronger the building, and its cutting difficulty will also increase with the steel bar. The thickness varies.



For thick steel bars, choose wire saws with larger beats. Because of the friction between the diamonds in the beats and the steel bars during the cutting process of thick steel bars, due to the great wear resistance of the steel bars, the diamond consumption is very fast during the cutting process. The diameter range of steel bars in reinforced concrete has a large span, covering diameters from 3mm-42mm. The thicker the steel bar, the higher the requirement for the diamond wire saw. The larger the diameter, the longer the cutting life of the wire saw. The more wear-resistant the carcass, the longer the service life of the wire saw. On the contrary, if the steel is thinner, If the diameter of beats is appropriately reduced, the sharpness can be increased and the cutting efficiency can be improved.

The choice of steel concrete cutting wire saw is related to the cutting machine

There are two kinds of wire saw machines for concrete cutting. The first is a hydraulic wire saw cutting machine. This kind of machine does not require high electrical power. It mainly cuts narrow concrete piers, beams and walls. The cutting method is from Cut from top to bottom. The second type is the orbital wire saw machine, which is suitable for buildings with larger cutting surfaces.

There is a big difference between the wire saws applicable to these two machines. The hydraulic wire saw motor has a low power and does not require high cutting efficiency during the cutting process. Therefore, the wire saw can choose a cheaper iron-based matrix, in the diamond part. , You can use some not too high grade diamonds, you can also complete the cutting of concrete.

However, the second type of wire saw has a large motor horsepower during the cutting process, and consequently a larger pulling force, and a larger cutting surface. In this case, the diamond wire saw needs to have higher cutting performance, so the diamond grade Parameters such as hardness also need to be improved.

Generally speaking, the wire saw for reinforced concrete cutting needs to be based on the cutting material and the machine. It must not be used to cut all steel-concrete structures with a wire saw. In this way, the efficiency of the wire saw is likely to be low, the service life is greatly reduced, and the cost-effectiveness is reduced. The emergence of the situation.

Wire saws are some of the most versatile and effective wire cutting tools for heavy-duty tasks, especially in construction, mining, or stonework. Using a proper wire saw will improve both the quality and performance of your work. We are going to take a look at wire saws so that you can get them right the first time and save some precious minutes materializing ideas faster.

What is a Wire Saw?

A wire saw consists of a multi-strand cable with diamond segments on beads and injected widia or multisaws to cut through wood. Wire saws can provide a very accurate cut, especially in the case of more complex or larger projects where normal sawing tools are not adequate.

Key Considerations for Choosing the Right Wire Saw

1. Material Type

The first factor to consider is the type of material you will be cutting. Wire saws are commonly used for cutting hard materials such as:

• Concrete
• Stone (marble, granite)
• Metals

For instance, a diamond wire saw is ideal for cutting through tough stone or reinforced concrete due to its strength and durability. Make sure the wire saw is compatible with the specific material to ensure smooth, efficient cuts.

2.Project Scale

Understanding the size and scope of your project is critical in choosing the right wire saw. Are you working on a large construction project or a smaller, more intricate job? Here's how to determine the best wire saw based on scale:

• Large-Scale Projects: For demolition or mining projects, you&#;ll need a heavy-duty, industrial-grade wire saw capable of cutting through thick and dense materials. Look for saws with high power output and larger cutting capacity.
• Small-Scale Projects: For smaller jobs, such as cutting countertops or performing precise masonry work, opt for a more compact, lightweight wire saw that offers better control and precision.

3.Cutting Speed and Precision

The cutting speed of a wire saw is influenced by the type of wire used and the machine&#;s power. If your project requires a high level of precision, such as cutting delicate stonework, you should select a wire saw designed for controlled, slow-speed cuts.

However, if speed is a priority for large cuts or demolition work, choose a saw with higher cutting speed capabilities. Diamond wire saws, for instance, can maintain high precision while delivering faster cutting speeds.

4.Wire Type

The type of wire used in a wire saw plays a significant role in its performance. There are various types of wires to choose from, each designed for specific tasks:

• Diamond Wire: Ideal for cutting hard materials like stone and concrete.
• Steel Wire: Used for less demanding cutting tasks like metal or softer stones.
• Plastic or Rubber-Coated Wire: Helps protect the material being cut from scratches, making it useful in projects requiring clean, smooth finishes.

5. Durability and Wear Resistance

A heavy-duty wire saw should be capable of withstanding long-term usage a lotlegant. If you are cutting abrasive materials (granite, Reinforced concrete), ensure that the wire has a good wear resistance.

Segregation of the larger diamond core from its supports will result in higher product quality but less wear life, whereas a good segregation pattern with more space between diamonds allows a longer run in time before the wire fails.

6 .Portability and Flexibility

It may also need to be portable, depending on your project's location. A lightweight and portable wire saw will be your best bet for any projects you are doing in remote locations or hard-to-access areas. Their flexible wire design means they can be used to cut in awkward spaces, around corners or anywhere else where a blade has trouble reaching.

7. Cost Efficiency

Unless for the purpose of using it professionally, you need to place a maintenance and replacement cost into consideration when buying wire saw_concat(min 10 years life). The diamond wire saws may be slightly pricier upfront, but the price is justified by the long term results they offer.

 

To sum up all the things, To choose a suitable wire saw for your project will need to take various aspects including material, scale of the layout, cutting speed and method, type as well as durability into account. Selecting wire saw that meets the unique requirements of your project will greatly increase its precision, productivity and cost-effectiveness.
