Hollow slab bridge reinforcing structure and hollow slab bridge reinforcing method
The invention provides a hollow slab bridge reinforcing structure and a hollow slab bridge reinforcing method. A plurality of upper steel belts are laid on the top face of a bridge at intervals in the longitudinal direction of the bridge; the multiple groove-shaped lower steel belts are laid on the bottom face of the bridge at intervals in the longitudinal direction of the bridge, and the two ends of the groove-shaped lower steel belts located on the two sides of the bridge are detachably connected to the lower portions of the side faces of the two opposite ends of the bridge correspondingly. The pull rods are inserted into hinge joints in the bridge at intervals in the longitudinal direction of the bridge, the top ends of the pull rods are connected to the corresponding upper steel belts, and the bottom ends of the pull rods are connected to the corresponding lower steel belts; and ultra-high performance concrete is poured in the grooves in the hinge joint, the beam bottom and the two side faces of the bridge. According to the reinforcing method, the bending and shearing resistance, structural integrity and rigidity of the hinge joint can be effectively enhanced, the overall bearing capacity of the damage hollow slab bridge is improved, the steel belt can be effectively prevented from being rusted, the service life of the steel belt is prolonged, construction is convenient, and operability is high.
本申请提供一种空心板桥梁加固结构及空心板桥梁加固方法，其多条上钢带沿桥梁的纵向上间隔地铺设于桥梁的顶面上；多条槽型下钢带沿桥梁的纵向上间隔地铺设于桥梁的底面上，且处于桥梁两侧位置处的槽型下钢带的两端分别可拆卸地连接于桥梁的相对两端的侧面下部处；多根拉杆沿桥梁的纵向上间隔地插设于桥梁上的铰缝中，且顶端连接于相对应的上钢带、底端连接于相对应的下钢带；铰缝、梁底以及桥梁两侧面的凹槽处均浇筑有超高性能混凝土。该加固方法可以有效增强铰缝处抗弯剪能力、结构整体性及刚度，提高病害空心板桥梁整体承载能力，可有效防止钢带锈蚀，延长其使用寿命，施工方便，可操作性较强。
