Pre-tensioning pre-stressed steel plate-concrete reinforcing method for box girder
The invention discloses a pre-tensioning pre-stressed steel plate-concrete reinforcing method for a box girder. A pre-tensioning pre-stressed steel plate-concrete reinforcing structure for the box girder comprises the box girder, a pre-stressed anchoring device, a pre-stressed positioning device, a pre-stressed steel strand and steel plate-concrete. The pre-stressed steel strand is constructed by adopting a pre-tensioning method. In the box girder reinforcing construction process, the pre-stressed steel strand is anchored to the pre-stressed anchoring device. After box girder reinforcing construction is completed, the pre-stressed steel strand is anchored to the steel plate-concrete. The box girder is reinforced through the pre-tensioning pre-stressed steel plate-concrete, and the steel plate-concrete can effectively improve the section rigidity of an original structure, and greatly improve the bearing capacity of the structure. The bonded prestress is adopted, so that the corrosion risk of the steel strand is avoided, and the reinforced structure is economical and durable.
本发明公开了一种用于箱梁的先张法预应力钢板‑混凝土加固方法，箱梁的先张法预应力钢板‑混凝土加固结构包括箱梁、预应力锚固装置、预应力定位装置、预应力钢绞线、钢板‑混凝土。所述预应力钢绞线为采用先张法施工。箱梁加固施工过程中，预应力钢绞线锚固于预应力锚固装置。箱梁加固施工完成后，预应力钢绞线锚固于钢板‑混凝土。先张法预应力钢板‑混凝土对箱梁加固，钢板‑混凝土能有效提高原结构的截面刚度，大幅提高结构承载能力。采用有粘结的预应力，避免了钢绞线锈蚀风险，加固后结构经济耐久。
