Reinforced concrete T-beam steel plate-concrete combined reinforcing structure and construction method
The invention discloses a reinforced concrete T-beam steel plate-concrete combined reinforcing structure and a construction method, and belongs to the technical field of bridge reinforcement and maintenance, the reinforced concrete T-beam steel plate-concrete combined reinforcing structure comprises a steel jacket box arranged on the outer side of a reinforced concrete T-beam in a sleeving mode, and a pouring cavity is formed between the steel jacket box and the reinforced concrete T-beam; the shear nail group is arranged on the inner surface of the steel jacket box; one end of each connecting reinforcing steel bar is implanted into the reinforced concrete T beam, and the other end of each connecting reinforcing steel bar extends into the pouring cavity; the reinforcing mesh is arranged in the pouring cavity, and the reinforcing mesh is bundled on the connecting reinforcing steel bars; and the grouting material is poured into the pouring cavity through pressure so as to connect the reinforced concrete T-beam with the steel jacket box through the connecting steel bars, the steel bar meshes and the shear nail groups. According to the existing reinforced concrete T beam, the bearing capacity of the bridge can be greatly improved, the construction period is short, the transformation cost is low, and the influence of road bridge construction on traffic is reduced to the minimum.
本发明公开了一种钢筋混凝土T梁钢板‑混凝土组合加固结构及施工方法，属于桥梁加固维修技术领域，其包括：套设在钢筋混凝土T梁外侧的钢套箱，钢套箱与钢筋混凝土T梁之间形成灌注腔；设置在钢套箱内表面的剪力钉群；多个连接钢筋，连接钢筋的一端植入钢筋混凝土T梁内，另一端延伸至灌注腔内；设置在灌注腔内的钢筋网片，钢筋网片捆扎在连接钢筋上；灌浆料，灌浆料压力灌注于灌注腔内，以通过连接钢筋、钢筋网片和剪力钉群将钢筋混凝土T梁与钢套箱连接。本发明既有钢筋混凝土T梁，可大幅度提高桥梁承载能力，施工工期短，改造成本低，将道路桥梁施工给交通的影响降到最低。
