Local reinforcing method for concrete silo
The invention provides a local reinforcement method for a concrete silo. A steel base plate is anchored on a surface of an outer wall of the silo; a U-shaped supporting frame is welded to the outer surface of the steel base plate; bolt holes are formed in the support frame; bolts penetrate through bolt holes of the supporting frames from outside to inside to abut against the outer surface of the steel base plate; the bolts are rotated to apply certain prestress to the steel base plate. According to the method, the bolts are used for externally supporting the steel plate to apply prestress, the defect that the requirement for anchoring is high is overcome, the bearing capacity to the supporting structure and the foundation is reduced, and the method has the advantages of being reasonable in structure, uniform in stress, good in cooperative work performance and the like.
本发明提供一种混凝土筒仓局部加固方法，在紧贴筒仓外壁表面锚固钢垫板；将U型支撑架焊接于钢垫板外表面；在支撑架上设置螺栓孔；将螺栓由外向内穿过支撑架螺栓孔抵接在钢垫板外表面；旋转螺栓以对钢垫板施加一定预应力。本发明提供的方法利用螺栓外撑钢板施加预应力，不仅克服了对锚固要求高的弊端，而且减小了对支撑结构和基础的承载力，具有结构合理、受力均匀、协同工作性能好等优点。
