Transverse active reinforcing structure of prestressed concrete box girder and construction method
The invention relates to a prestressed concrete box girder transverse active reinforcing structure and a construction method, and belongs to the technical field of bridge engineering reinforcement, the prestressed concrete box girder transverse active reinforcing structure comprises a pouring groove formed in a box girder top plate and a first reinforcing piece arranged in the pouring groove, the pouring groove is longitudinal, and the pouring groove is formed in a crack of the top plate and penetrates into the crack; the first reinforcing piece comprises reinforcing plates fixedly arranged on the side wall of the pouring groove, the reinforcing plates are located on the longitudinal side wall of the pouring groove, and the first reinforcing piece further comprises a first pulling piece used for pulling the reinforcing plates on the two sides to be close to each other. The active reinforcing structure further comprises a second pulling piece, and the second pulling piece is used for acting on the end faces of the flange plates of the box girder and driving the flange plates on the two sides of the box girder to have the movement tendency of getting close to each other. And a third pulling piece is arranged in the box girder, acts on the lower surface of the top plate and is used for pulling the middle of the top plate to have the movement tendency towards the bottom plate. The reinforcing device has the advantage that the reinforcing effect on the box girder is improved.
本申请涉及一种预应力混凝土箱梁横向主动加固结构及施工方法，属于桥梁工程加固技术领域，包括开设在箱梁顶板上的浇筑槽和设置在浇筑槽内的第一加固件，浇筑槽呈纵向，浇筑槽开设在顶板裂缝处并深入裂缝，第一加固件包括固定设置在浇筑槽侧壁上的加固板，加固板位于浇筑槽纵向侧壁上，第一加固件还包括用于拉动两侧的加固板相互靠近的第一拉动件；主动加固结构还包括第二拉动件，第二拉动件用于作用于箱梁翼缘板的端面、驱使箱梁两侧的翼缘板具有相互靠近的运动趋势；箱梁内部设置有第三拉动件，第三拉动件作用于顶板的下表面、用于拉动顶板的中部具有朝向底板的运动趋势。本申请具有提高对箱梁的加固效果的优点。
