The main reason for strengthening the column

Column reinforcement technology Every element of any building structure needs repair work sooner or later, including reinforcement. This type of work is only carried out in extreme cases, which can be:

• Component deformation, mechanical damage;

• Destruction of materials (concrete and steel) due to aggressive environments;

• Rebar corrosion (damage);

• When the load on the component increases;

• Error correction;

• Violation of technology during work;

• The difference between the actual properties of the material.

Carbon fiber better than other materials for column reinforcement?

The use of carbon fiber in construction is a fairly new approach. It has been used in Russia since 1998. In such a short period of time, carbon fiber has been able to prove that it is one of the most effective materials, and it is actually irreplaceable.

It has the following characteristics:

• Heat resistance;

• Resistant to impact and chemical environment;

• The service time is practically unlimited;

• Use several layers when necessary;

• During the construction process, there is no need to close the entire building;

• Material weight

• Material strength.

In terms of technical performance, even in terms of hardness, carbon fiber is 3 times higher than metal (until recently, carbon fiber was the most durable material in construction). Carbon fiber is used in industries, construction and other fields, and is less used in the aerospace field.

One of the main advantages of using carbon fiber is accessibility, speed and ease of implementation (the working technique is to bond the material to the prepared surface). In many respects, carbon fiber is several times that of other materials.

The advantages of using carbon fiber materials

As long as the use of carbon fiber materials, carbon fiber or fiber-reinforced concrete, the repair work of old buildings and the repair work of new buildings can significantly reduce costs and shorten implementation time.

The benefits of using these materials include:

• Because the material is lightweight, there is no need to attract heavy equipment to work;

• By using external reinforcement technology, the time for carbon fiber reinforced concrete can be reduced by up to 10 times;

• The structure has the ability to withstand a load that is 4 times higher than the allowable level of other materials;

• The structure will not become heavier;

• The material does not undergo corrosion changes;

• If mistakes are made in the design and preliminary construction work, they can be easily corrected;

• The new material will last at least 75 years.

Carbon fiber reinforcement is a fast and effective technology. In the case of damage to the supporting structure, it is indispensable to use carbon fiber or carbon fiber for reinforcement, because it helps to significantly reduce the consequences of damage, not only to restore the bearing capacity of the structure, but also to increase the bearing capacity. In the future, reinforced concrete will be protected from moisture and steel corrosion. And it is also subject to most possible mechanical damage.

Strengthening the supporting structure can simplify the construction process. But you can only delegate any work in this area to professionals. After all, technology is essential to achieve the desired results.

The reinforcement of composite materials is becoming an increasingly common and commonly used technology. Therefore, the technology used to produce single composite materials and external reinforcement systems is a niche market that more and more companies strive to enter. However, only in the case of technically competent methods, and refuse to save excessive costs on the basis of materials and technology, it is possible to produce competitive materials.

Reinforcing reinforced concrete columns with carbon fiber can improve the following structural indicators:

• Carrying capacity;

• The resistance of the chromatographic column to the external environment;

• Allowable load level.

The advantage of this method of strengthening the column is the following characteristics of the material:

• Carbon fiber will not change the weight or deform the chromatographic column;

• No need to use heavy equipment when working;

• Carbon fiber reinforcement can restore 90% of the bearing capacity of the column.

What is the method for column reinforcement work?

There are several types of work aimed at strengthening the pillars. There are several ways to work vertically, horizontally, at a certain angle or at the same time. If the process is carried out vertically, chamfer at corners or supports on rounded corners. If it is horizontal, the height of the object must be placed in two or one direction. In the third case, the lashing of the structural head must be done at an angle of 45° or 90° in the direction of action.
