Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete anti-seismic, more specifically, relate to a reinforced concrete column anti-seismic reinforcing device. BACKGROUND

[0002] With the continuous acceleration of urbanization, reinforced concrete structures are widely used in high-rise buildings and bridges and other important facilities. However, the occurrence of natural disasters such as earthquakes may cause serious damage to these structures, especially for the key load-bearing component of reinforced concrete columns, whose seismic performance directly affects the overall safety of the building. Therefore, improving the seismic capacity of reinforced concrete columns has become an important issue in the current construction field.

[0003] Traditional anti-seismic reinforcement methods mostly rely on external reinforcement materials such as carbon fiber cloth or steel plates, which can enhance the seismic capacity of the structure to some extent, but have problems such as high construction difficulty, limited reinforcement effect, and inconvenient maintenance in the later period. In view of these deficiencies, in recent years, structural engineers and researchers have proposed a variety of innovative reinforcement technologies, one of which is to enhance the seismic performance of reinforced concrete columns by designing special anti-seismic reinforcement devices, which has received considerable attention and application.

[0004] In existing anti-seismic reinforcement devices, most of them are integrated structures, which usually require close combination of the column and the reinforcement material, with a complicated installation process and limited reinforcement effect. In order to solve these problems, designing a reinforcement device that can effectively disperse seismic force, has strong adaptability, is easy to install, and has significant reinforcement effect has become a difficult problem to be solved in engineering technology.

[0005] At present, there are still many challenges in the technology of reinforced concrete column anti-seismic reinforcement, especially in the adjustability, stability and construction convenience of the device structure, which still needs further optimization and improvement. Therefore, designing a new type of reinforced concrete column anti-seismic reinforcement device not only can improve its seismic performance, but also can simplify the construction process, reduce labor cost, and be convenient for later maintenance, which has important theoretical and practical significance.
