AI Technical Summary
Traditional reinforcement methods require unloading during construction, are inefficient, and have poor spatial adaptability. They are difficult to quickly and efficiently reinforce existing concrete beams under load, and are particularly ineffective in engineering scenarios with large spans, limited construction space, and tight schedules.
The structure employs a combination of end anchoring components, middle force-applying components, prestressing tendons, and hooks. By adjusting the height of the hooks under load, the prestressing tendons generate tension, applying an upward supporting force to the concrete beam, thus achieving rapid reinforcement.
It enables construction without unloading under load, shortens the construction period, improves construction efficiency, has a simple structure, is easy to construct, has flexible stress adjustment, and improves load-bearing capacity and reinforcement effect.
