Hollow slab beam shear-resistant reinforcing method and hollow slab beam shear-resistant reinforcing device
The invention provides a hollow slab beam shear-resistant reinforcing method and a hollow slab beam shear-resistant reinforcing device. The hollow slab beam shear-resistant reinforcing method comprises the steps that: a sunken area is arranged at the upper end of a bridge; at least one through hole is formed in a hinge joint of a hollow slab beam of the bridge, and the through hole is communicated with the sunken area; an upper connecting piece is fixedly arranged in the sunken area, and a lower connecting piece is fixedly arranged at the lower end of the bridge; an opposite-pull rod is arranged in the through hole, and the two ends of the opposite-pull rod are fixedly connected to the upper connecting piece and the lower connecting piece respectively; and the sunken area is repaired. According to the invention, the upper connecting piece, the lower connecting piece and the opposite-pull rod form a reinforcing assembly, so that the transverse connection between a slab and a beam can be enhanced, the stress state of a single beam is weakened, the vibration of the beam and the slab is avoided, and the cracking and discretization of a crack repairing adhesive are avoided.
本发明提供了一种空心板梁抗剪加固方法及空心板梁抗剪加固装置。该空心板梁抗剪加固方法包括：在桥梁上端设置凹陷区域；在桥梁的空心板梁的铰缝中设置至少一个通孔，所述通孔与所述凹陷区域相连通；在所述凹陷区域处固定设置上连接件，在所述桥梁下端固定设置下连接件；在所述通孔中设置对拉杆，所述对拉杆两端分别固定连接于所述上连接件和所述下连接件；修补所述凹陷区域。本发明中，上连接件、下连接件和对拉杆组成加固组件，其可使板梁之间的横向联系增强，削弱单梁受力状态，避免梁板振动，从而避免裂缝修补胶的开裂、离散化。
