Reinforcing device and method for pre-bent steel beam and UHPC grouting hollow slab girder bridge
The invention provides a pre-bent steel beam and UHPC grouting hollow slab girder bridge reinforcing device which is used for reinforcing a hollow slab girder, the hollow slab girder is provided with a hinge joint and comprises a pre-bent steel beam and an anchor rod, the hinge joint of the hollow slab girder is provided with an anchoring tension hole, the pre-bent steel beam is provided with a through hole, and the anchor rod is connected with the pre-bent steel beam. The through hole of the pre-bent steel beam is matched with the anchoring tensioning hole, the anchor rod penetrates through the through hole of the pre-bent steel beam and the anchoring tensioning hole, and the two ends of the anchor rod are connected with the pre-bent steel beam and the hollow slab beam respectively. Prestress is applied to the hollow slab beam through the pre-bent steel beam, the problem that the hinge joint of the hollow slab beam is poor in transverse transmission capacity is solved, the transverse connection capacity of the hollow slab beam is improved, and the longitudinal bending bearing capacity is improved.
本发明提供了一种预弯钢梁和UHPC压浆的空心板梁桥的加固装置，用于空心板梁的加固，所述空心板梁上设有铰缝，包括预弯钢梁、锚杆，所述空心板梁的铰缝处设有锚固张拉孔，所述预弯钢梁上设有通孔，所述预弯钢梁的通孔与所述锚固张拉孔相匹配，所述锚杆穿过所述预弯钢梁的通孔和所述锚固张拉孔，所述锚杆的两端分别与所述预弯钢梁、所述空心板梁连接。本发明通过预弯钢梁对空心板梁施加预应力，解决了空心板梁铰缝横向传递能力差的问题，增加了空心板梁的横向连接能力，提高了纵向抗弯承载力。
