Fabricated hollow slab oblique section shear-resistant reinforcing device and construction method
The invention discloses a fabricated hollow slab oblique section shear-resistant reinforcing device and a construction method, the fabricated hollow slab oblique section shear-resistant reinforcing device is formed by splicing a plurality of hollow slab girders, hinge joints are arranged between adjacent hollow slab girders, a plurality of oblique prestressed tendons are arranged in the hinge joints at intervals, and the two ends of each oblique prestressed tendon are anchored at the top and the bottom of the corresponding hollow slab girder after being tensioned. And grouting anchoring bodies are arranged on the peripheries of the inclined prestressed tendons. According to the fabricated bridge structure, the oblique prestressed tendons are adopted, the cross section shear capacity of the fulcrum of the fabricated bridge beam plate is improved, the structure is simple, construction is convenient, secondary damage to the existing beam plate can be effectively reduced, and the technical performance of the bridge beam plate is guaranteed.
本发明公开了一种装配式空心板斜截面抗剪加固装置及施工方法，由多个空心板梁拼装而成，相邻空心板梁之间具有铰缝，铰缝内间隔布置多个斜向预应力筋，斜向预应力筋两端张拉后锚固于空心板梁顶部和底部，斜向预应力筋外周设置注浆锚固体。本发明的装配式桥梁结构，采用斜向预应力筋，提高装配式桥梁梁板支点截面抗剪承载力，构造简单，施工方便，可有效减小对既有梁板的二次损伤，保证桥梁梁板技术性能。
