Transverse reinforcing system for existing hollow slab girder bridge and construction method of transverse reinforcing system
The invention discloses a transverse reinforcing system for an existing hollow slab girder bridge and a construction method of the transverse reinforcing system. The system comprises transverse reinforcing units distributed in the longitudinal direction of a hollow slab girder body. Each transverse reinforcing unit comprises a prestressed steel structure mounted on the lower side of the bottom of the hollow slab through a bolt and a connecting steel structure mounted on the outer side of an outer web of a side plate of the hollow slab through a bolt; the prestressed steel structure is transversely arranged, a main body of the prestressed steel structure is I-shaped steel or box-shaped section steel, a prestressed steel beam and a mounting assembly thereof are preset in the prestressed steel structure before mounting, the prestressed steel beam is tensioned and fixed after mounting, and the prestressed steel beam extends from one end of the prestressed steel structure to the other end of the prestressed steel structure; the connecting steel structures are located at the two ends of the prestressed steel structure, the bottom ends of the connecting steel structures and the ends of the prestressed steel structure are bolted or welded and fixed, and stiffening plates are arranged in the connecting areas of the connecting steel structures and the prestressed steel structure. The safety and durability of the existing hollow slab girder bridge are improved, the construction difficulty is low, and the dead weight increase is small.
本发明公开了一种既有空心板梁桥横向加固系统及其施工方法，该系统包括沿空心板梁体纵向分布的横向加固单元，横向加固单元包括通过螺栓安装在空心板板底下侧的预应力钢结构和通过螺栓安装在空心板边板外腹板外侧的连接钢结构；预应力钢结构横向设置且主体为工字钢或箱型截面钢，预应力钢结构在安装前内部预设有预应力钢束及其安装组件、在安装后将预应力钢束张拉并固定，预应力钢束从预应力钢结构的一端附近延伸至另一端附近；连接钢结构位于预应力钢结构的两端，连接钢结构的底端与预应力钢结构的端部栓接或者焊接固定且二者的连接区域设置有加劲板。本发明提高了既有空心板梁桥的安全性和耐久性，施工难度低，自重增加小。
