Bridge external prestress reinforcing structure
This invention relates to the field of bridge reinforcement technology, and more particularly to an external prestressed reinforcement structure for bridges, including a bridge body and reinforcement components. The reinforcement components include a fixing member with a fastening bolt at its lower left end. The fixing member is threadedly connected to the bridge body via the fastening bolt. This invention, by incorporating components such as a support plate, sliding roller, elastic compression plate, and return spring, can automatically adjust its position during the natural shrinkage of the concrete repair layer. The sliding roller slides at the bottom of the elastic sealing plate, and in conjunction with the tension of the return spring, continuously applies reverse pressure, ensuring that the sealing plate remains tightly fitted to the repair layer. The elastic compression plate, under the action of the support spring and telescopic sleeve, can evenly distribute pressure, adapting to the curvature changes of the repair layer, avoiding localized stress concentration, and ensuring that the sealing protection of the concrete repair layer does not fail during the shrinkage and shaping process, preventing crack recurrence.
