Reinforced concrete materials are characterized by fire resistance, strong plasticity and good durability, and are widely used in real projects. But it will also be disturbed by quality and service life issues, so it is still necessary to regularly strengthen the concrete. Whether the reinforcement technology is perfect will have a direct impact on the project. For example, it will affect the service life and safety of the project. This paper not only analyzes the characteristics of reinforcement technology, but also puts forward some application suggestions.

Summarize the stress characteristics and reinforcement principles of concrete reinforced structures

Before strengthening the concrete, we should fully understand the stress characteristics of the concrete reinforcement structure. This is because the engineering construction itself has the capacity to bear the force, and the progress of the concrete reinforcement technology can be regarded as the secondary force. Therefore, it is necessary to pay attention to the coordination of the engineering structure and the reinforced concrete structure in order to perform their duties. Based on this, the following principles need to be observed when strengthening concrete:

(1) The principle of sharing the load as much as possible. This principle means that when preparing to reinforce the concrete structure, it is necessary to maintain the original concrete structure and retain the original engineering structure performance to avoid damage to the original structure to the greatest extent. This can significantly reduce the workload, save money, and ensure satisfactory reinforcement results.

(2) The principle of avoiding destruction. It means that while strengthening the concrete, various protective measures must be actively taken to protect the original structural integrity of the project. In general, it is to try our best to reduce the possibility of negative effects.

(3) The principle of comprehensive verification. Before carrying out concrete reinforcement for the project, we must first analyze and check the force of the project after the reinforcement. It is not only necessary to ensure that the structure of the project after reinforcement remains the same, but also to fully understand the subsequent development of the reinforced part, and pay attention to whether the rigidity of the member has changed after reinforcement.

Reasons for structural reinforcement of concrete

(1) At this stage, my country still lacks complete methods and materials on concrete structure design, so the possibility of quality problems in engineering construction is increasing.

(2) In the process of project construction, the quality of the project will be restricted due to poor construction management, improper construction methods or cutting corners by the construction unit.

(3) The design has become more and more standardized, and the design standards have been continuously improved. Therefore, if the concrete structure is designed blindly in accordance with the previous design standards and specifications, it will deviate from the modern design standards and seriously affect the quality of the concrete structure.

(4) Sometimes natural disasters can also cause damage to the project, which will lead to building damage, such as earthquakes, freeze-thaw and other natural disasters.

(5) Now people have higher requirements for the use function of the project, so the original structure can no longer meet people's needs, and the original structure needs to be improved and reinforced.

Analysis of reinforced concrete structure strengthening technology

The longer it is used, the more hidden dangers the concrete structure will have, such as cracks, reduced seismic performance, etc. The appearance of these problems will affect the quality of the project. Faced with this situation, we can use concrete reinforcement technology to improve this problem, but in reality, there are the following methods.

• Replacement concrete method

• Section reinforcement method

• Outsourcing Steel Structure Method

• Structure potting

• Additional fulcrum reinforcement method

• Prestressed reinforcement method

• Externally bonded steel plate reinforcement method

• FRP reinforcement method

The above several reinforcement techniques are currently the most important methods of strengthening concrete structures. However, in the process of actual project construction, it is necessary to seek truth from facts, and make the most suitable choice for different project purposes, cost planning and project effect requirements.

Reinforced concrete structural reinforcement engineering application

This article has organized and analyzed the main technology of reinforced concrete reinforcement structure, but if we want to truly achieve the goal we need to achieve, we need to do the following aspects.

• The reinforcement plan should be selected according to the actual project

• Flexible mastering of different reinforcement engineering techniques

• Need to strictly control the quality of the project

  
  

Concluding remarks

In summary, the research object of this article is concrete structure, and the reinforcement technology of concrete structure is analyzed in detail. First, summarize the stress characteristics and reinforcement principles of concrete reinforced structures. Secondly, it analyzed why the concrete structure should be reinforced.
