[0026] Referring to Figure 1 , Figure 2 and Figure 4 , it is prestressed intelligent tensioning practical training device of the utility model embodiments, including main beam 21, steel strand 20, through core jack 7, work anchor one 1, work anchor two 15, tool anchor one 9, tool anchor two 18, work anchor gasket one 2, work anchor gasket two 16, tool anchor clamp one, tool anchor clamp two 19, spring 17, displacement sensor 5, pressure sensor 4 and displacement sensor baffle 8.

[0027] Specifically, referring to Figure 1 and Figure 6 , main beam 21 is equipped with hole 24, and steel strand 20 is arranged in hole 24, and the two ends of steel strand 20 respectively extend outside main beam 21, and steel strand 20 is bent into a substantially U-shaped, work anchor one 1 is connected to one end of steel strand 20, and part of the structure of work anchor one 1 is arranged in hole 24, work anchor two 15 is connected to the other end of steel strand 20, and part of the structure of work anchor two 15 is arranged in hole 24, and beam gasket 3 is arranged between work anchor two 15 and main beam 21. Referring toFigure 2 As shown, the working anchor pad one 2 is connected with the working anchor one 1, the tool anchor two 18 is connected with the steel strand 20 at one end close to the working anchor two 15, the tool anchor one 9 is located at one side of the working anchor one 1 away from the main beam 21, the tool anchor clamp one is clamped with the steel strand 20, the tool anchor clamp one is located at one side of the working anchor one 1 away from the main beam 21, the tool anchor clamp one is in abutment with the tool anchor one 9, and the tool anchor clamp one can limit the tool anchor one 9 from being separated from the steel strand 20. The through-type jack 7 is connected with the steel strand 20 at one end close to the working anchor one 1, the through-type jack 7 is located between the working anchor pad one 2 and the displacement sensor baffle 8, the through-type jack 7 comprises an inner cylinder 71 and an outer cylinder 72, the inner cylinder 71 can be extended relative to the outer cylinder 72, the steel strand 20 is arranged in the inner cylinder 71 and the outer cylinder 72, the pressure sensor 4 is in abutment between the outer cylinder 72 and the working anchor pad one 2, and the displacement sensor 5 is used to detect the displacement of the inner cylinder 71 relative to the outer cylinder 72.

[0028] On the other side of the steel strand 20, referring to Figure 4 As shown, the tool anchor two 18 is located at one side of the working anchor two 15 away from the main beam 21, the tool anchor clamp two 19 is clamped with the steel strand 20, the tool anchor clamp two 19 is located at one side of the tool anchor two 18 away from the main beam 21, the tool anchor clamp two 19 is in abutment with the tool anchor two 18, the tool anchor clamp two 19 can limit the tool anchor two 18 from being separated from the steel strand 20, the working anchor pad two 16 is connected with the working anchor two 15, the spring 17 is in abutment between the tool anchor two 18 and the working anchor pad two 16, the spring 17 is arranged as a high-strength spring 17, and the spring 17 is sleeved on the outer periphery of the steel strand 20.

[0029] In use, the prestressed intelligent tensioning training device, the through-type jack 7 is started, the inner cylinder 71 extends relative to the outer cylinder 72, and the inner cylinder 71 pulls the tool anchor I 9 during the extension. Since the tool anchor clamp I restricts the movement of the tool anchor I 9, and the tool anchor clamp II 19 restricts the movement of the tool anchor II 18, the inner cylinder 71 is equivalent to pulling the steel strand 20. During the pulling of the steel strand 20, the steel strand 20 moves in the direction of the tool anchor I 9, and the positions of the working anchor I 1 and the working anchor II 15 remain unchanged. The steel strand 20 drives the tool anchor II 18 to compress the spring 17. When the spring 17 is compressed, the reduction in its structure is proportional to the stretching of the steel strand 20. The more the spring 17 is compressed, the more the steel strand 20 is stretched. The pressure used by the spring 17 is much smaller than the tension of the jack directly tensioning the steel strand 20, which reduces the tension consumed by the jack during tensioning and makes the structure safer during construction. The overall safety of the structure is guaranteed, which facilitates the popularization of prestressed technology in school teaching and provides students with practical teaching.

[0030] The use of the device can completely simulate the real prestressed steel strand 20 tensioning process, significantly improve the quality, efficiency and safety of the prestressed tensioning process training, promote the intelligent development of the prestressed training teaching in the engineering construction industry, and realize the operability of the students' prestressed tensioning in the school training site.

[0031] The device is used in real prestressed training sites, and the displacement value is checked in real time to realize the "double control" of stress and displacement. At the same time, through the elastic force of the high-strength spring 17, the tension is significantly reduced, further improving the quality and safety of the prestressed tensioning. In addition, the patent can also standardize the tensioning process, reduce the prestressed loss, realize the intelligent control of the tensioning program, and avoid the influence of human and environmental factors on the construction quality. The prestressed intelligent tensioning training device provides valuable practical opportunities for students in school. By simulating real tensioning scenarios, students can familiarize themselves with the entire process of the tensioning process, master equipment operation and maintenance skills, and improve their ability to solve practical problems. This training method not only promotes the popularization of prestressed tensioning technology in college practice teaching, but also helps to cultivate high-quality professionals.

It can be understood that since the steel strand 20 is bent into a generally U-shaped structure after passing through the hole 24, the part of the steel strand 20 that passes out of the main beam 21 is arranged obliquely, and if the through-type jack 7 is not supported by an object, the through-type jack 7 will bend the steel strand 20. By suspending the through-type jack 7 by the hook 6, it is not necessary to arrange a support frame 13 below the through-type jack 7, thereby reducing the occupied space.
