Multilayer prestressed fiber cloth reinforcing device and reinforcing method capable of simultaneously tensioning in two directions
The invention discloses a bidirectional simultaneous tensioning multilayer prestressed fiber cloth reinforcing device and method. The reinforcing device comprises a first reinforcing assembly, a second reinforcing assembly, a third reinforcing assembly, a first pedestal, a tensioning screw assembly and a second pedestal. Each reinforcing assembly comprises an anchor shuttle set, fiber cloth and oval steel shafts fixed to the two ends of the fiber cloth. When a to-be-reinforced component is reinforced, firstly, anchor shuttle groups are assembled in sequence, fiber cloth is wound on each elliptical steel shaft, then the elliptical steel shafts wound with the fiber cloth are placed in the corresponding anchor shuttles, the anchor shuttles are placed on a pedestal in sequence, the pedestal is fixed on the to-be-reinforced component, and then the to-be-reinforced component is reinforced. The nut at the end of the tensioning screw is screwed bidirectionally to drive the movable anchor shuttle to move horizontally. The multiple layers of fiber cloth are anchored and tensioned in a dispersed mode through the multiple reinforcing assemblies, then the to-be-reinforced component is reinforced, the bearing capacity and rigidity of the to-be-reinforced component are improved, efficient anchoring can be achieved, and operation is easy and convenient.
本发明公开了一种双向同时张拉的多层预应力纤维布加固装置及加固方法，该加固装置包括第一加固组件、第二加固组件、第三加固组件、第一台座、张拉螺杆组件和第二台座。各个加固组件包括锚梭组、纤维布和固定在纤维布两端的椭圆钢轴。本发明在对待加固构件进行加固时，首先按顺序组装锚梭组，将纤维布缠绕在各椭圆钢轴上，然后将缠绕有纤维布的椭圆钢轴放入到对应的锚梭中，各锚梭按顺序放在台座上，并将台座固定在被加固构件上，双向拧动张拉螺杆端部的螺母带动移动锚梭水平移动。本发明通过多个加固组件将多层纤维布“分散”锚固和张拉，进而对待加固构件进行加固，提高了待加固构件的承载力和刚度，不仅可以高效锚固，而且操作简便。
