Steel structure engineering chooses economic reasonable and reliable reinforcement measures

structural characteristics.

Rooms mainly refer to factory buildings composed of load -bearing components such as steel beams and columns, roofs, and roofs.

With the continuous improvement of the quality and output of steel products in my country, the superiority will become more and more obvious, which will further expand the application of the steel structure in the construction industry.

The steel structure has light weight, span Discussion-on-STRUCTURE-FIRE-Co-Application Large, light houses, short construction cycle, fire resistance, convenient disassembly, convenient disassembly, convenient disassembly, convenient disassembly, easy to disassemble The advantages of recycling, especially at the building site, are widely used.

However, to improve the quality, quantity and life of the steel structure plant, it must be tested and reinforced. In particular, the load -bearing components of some steel structure factories must not only strengthen the quality control of the on -site construction, but also adopt a scientific and effective reinforcement design solution to largely ensure the stability and use of the steel structure plant.

Reinforcement technology research.

When optimizing the reinforcement design of the steel structure plant, it is necessary to evaluate based on the structural reliability of the site to provide a reliable theoretical basis for formulating a reinforcement plan. Specifically, the entire reinforcement design process includes the calculation of the steel structure bearing capacity, component processing and drawing construction drawings.

The scope and degree of reinforcement varies depending on the requirements. At the same time, pay attention to the coordination of the reinforcement and the original structure. Specific analysis of the main points of reinforcement design of steel structure factories:

2.1 has a comprehensive understanding of the performance and structure of the steel structure plant.

To reinforce the steel structure plant, we must first understand the reliability of its structure, including the performance, structural system, and its defects and damage of the steel structure material. Analyze the stress status and water resistance of the steel structure plant, and conduct unified research on it to provide a basis for subsequent reinforcement design.

2. Choose the economically reasonable and reliable reinforcement measures.

The reinforcement design scheme of the steel plant should fully consider the structural stress condition and the characteristics of reinforcement.

On the basis of ensuring the reasonable and reliable overall structure, selecting reinforced measures for economical and reasonable construction. Under the existing construction conditions, the new and old structure and new material connection technology are adopted, and comprehensive technical indicators are considered as much as possible.

In addition, in the optimization design of the steel structure plant reinforcement plan, effective measures must be taken to reduce the adverse effects on the surrounding environment and neighboring buildings, and shorten the construction cycle.

Make full use of the original building structure.

To avoid damage to the original structure, the carrying capacity of the original structure should be used as much as possible. For reliability analysis and testing of load -bearing components of the plant itself, fully understand its existing carrying capacity, and then retain more original components according to the test report. Due to the large amount of disassembly, the steel structure plant easily causes severe damage to the component and the difficulty of connecting the new and old structure, which affects the reinforcement effect. Therefore, the steel structure plant has great hidden safety hazards in the later use.

2.4 Strengthen construction quality control.

In the reinforcement construction of the steel structure plant, the actual structural test should be strengthened, the actual situation and damage of the existing structure should be accurately grasped, and hidden safety hazards should be excluded in time.

Quality control measures such as steel structure, welding, installation, bolt connection, anti -corrosion fire coatings, and stamping steel plate installation were adopted.

When strengthening, check the quality of the structure. If defects are found, it should be dealt with in time to ensure that the reinforcement scheme is reliable and effective, and the defects found in the process of reinforcement should be treated in a timely manner.

Many drilling steel joints must be checked by quality, and can only be put into use only in accordance with the standard.

In addition, when reinforcing the steel structure plant, it is necessary to clarify the construction load and fatigue requirements of the steel structure plant in accordance with the relevant quality control technical standards and quality inspection systems to ensure the safety and stability of the entire plant. When installing machinery and equipment, the equipment must be measured to ensure the accuracy of the operation of the construction personnel.

Reinforcement new plan.

The reinforcement steel structure with prestressed carbon fiber board is a new type of reinforcement method. It can not only save unloading work capacity, reduce losses caused by stopping, but also turn passive reinforcement into active reinforcement. Giving full play to the fiber materials Strong, improving structural carrying capacity, and saving reinforcement costs are a very practical method for reinforcement in modern scenes.

In a large span engineering, in the case of 2cm carbon plate pull -up control of more than 10t, prestressed reinforcement technology was well used.
