Box girder web reinforcing structure and box girder web reinforcing method
The invention discloses a box girder web reinforcing structure and a box girder web reinforcing method. The box girder web reinforcing structure comprises a web, a perforated steel plate, a reinforcing anchor rod, anchor bolts, rectangular steel pad drill holes and structural adhesives. A plurality of drill holes are formed in the web, and the reinforcing anchor rod is perpendicular to the web andarranged in the drill holes. The perforated steel plate is tightly attached to the web and fixed to one side of a box girder cavity, and holes allowing the reinforcing anchor rod to pass through areformed in the perforated steel plate. The anchor bolts are connected to the two ends of the reinforcing anchor rod through threads, and the diameters of through holes of the anchor bolts are the sameas that of the reinforcing anchor rod. A rectangular steel base plate is fixed to one side outside the drilled box girder, and a hole allowing the reinforcing anchor rod to pass through is formed in the center of the rectangular steel base plate. The box girder web reinforcing structure is simple in form and convenient to construct, the web rigidity and the overall stress performance of the web are enhanced, the overall structural stability of the box girder of the prestressed concrete cable-stayed bridge is improved, the material manufacturing cost and the construction cost are low, and goodeconomic benefits are achieved.
本发明公开了一种箱梁腹板加固结构及箱梁腹板加固方法，包括腹板、带孔钢板、加固锚杆、锚固螺栓、矩形钢垫钻孔及结构胶。所述腹板上有若干钻孔，加固锚杆垂直于腹板、设置于钻孔内。所述带孔钢板紧贴腹板、固定于箱梁腔一侧，带孔钢板上设置供加固锚杆通过的孔。所述锚杆螺栓通过螺纹连接于加固锚杆两端，锚杆螺栓的通孔直径与加固锚杆直径相同。所述矩形钢垫板固定于钻孔的箱梁外一侧，矩形钢垫板的中心设置供加固锚杆通过的孔。本发明提供的箱梁腹板加固结构形式简单，施工方便，实现了腹板刚度及其整体受力性能的增强，提高了预应力混凝土斜拉桥箱梁的整体结构稳定性，材料造价、施工成本低，具有良好的经济效益。
