Reinforcing device and reinforcing method based on multi-layer fiber cloth prestress application
The invention discloses a reinforcing device and reinforcing method based on multi-layer fiber cloth prestress application. The reinforcing device comprises a tensioning end anchorage device, a fixed end anchorage device, a tensioning screw rod, an anchorage device bracket, a combined pressing strip, a jack, an ejector block and fiber cloth; and the anchorage device bracket and the fixed end anchorage device are connected with a reinforced component through the combined pressing strip, the ejector block, the anchorage device bracket and the tensioning end anchorage device are connected through the tensioning screw rod, and the tensioning end anchorage device moves on the anchorage device bracket in the horizontal direction under the action of the jack. When the reinforced component is reinforced, the fiber cloth is bent oppositely and then wound between an anchor shaft of the tensioning end anchorage device and an anchor shaft of the fixed end anchorage device to form multi-layer fiber cloth, and prestress is applied to the multi-layer fiber cloth at the same time, so that the reinforced component is reinforced. According to the combined pressing strip, the distance between the multi-layer fiber cloth and the surface of the reinforced component is shortened, the reinforcing effect is enhanced, and the reinforcing efficiency is improved.
本发明公开了一种基于多层纤维布预应力施加的加固装置及加固方法，该加固装置包括张拉端锚具、固定端锚具、张拉螺杆、锚具托架、组合压条、千斤顶、顶块和纤维布；锚具托架和固定端锚具通过组合压条与被加固构件连接，顶块、锚具托架和张拉端锚具通过张拉螺杆连接，张拉端锚具在千斤顶的作用下，在锚具托架上沿水平方向移动。本发明对被加固构件进行加固时，将纤维布对弯后，缠绕在张拉端锚具的锚轴和固定端锚具的锚轴之间形成多层纤维布，通过对多层纤维布同时施加预应力进而对被加固构件进行加固；本发明中的组合压条缩小了多层纤维布与被加固构件表面的距离，增强了加固效果，提高了加固效率。
