Prestressed fiber cloth tensioning system applied to bridge reinforcing construction
A prestressed fiber cloth tensioning system applied to bridge reinforcing construction relates to a bridge reinforcing method and comprises a fixing mechanism, fiber cloth and a tensioning mechanism. The fixing mechanism comprises a thin steel plate and two groups of pressing tools; the tensioning mechanism comprises a tensioning fixing base, a counter-force block, a jack, a circular shaft, a lead screw and a pressing plate. The jack is connected between the tensioning fixing seat and the counter-force block, a tensioning stroke groove is formed in the tensioning fixing seat, the circular shaft is arranged in the tensioning stroke groove, and the circular shaft is connected with the counter-force block through a lead screw; a pressing plate is arranged on one side of the tensioning fixing base and connected with the tensioning fixing base through a support. A pressing strip is arranged between the pressing plate and the tensioning fixing seat; one end of the fiber cloth is pressed between the thin steel plate and the bridge, the fiber cloth is pressed by the pressing tool, the fiber cloth passes through the pressing plate and the pressing strip and then bypasses the circular shaft, and the other end of the fiber cloth passes through the pressing strip and the pressing plate. And in the tensioning process of the fiber cloth, the phenomena of collapse and slippage are avoided.
一种应用于桥梁加固施工中的预应力纤维布张拉系统，涉及桥梁加固的方法，包括固定机构、纤维布和张拉机构；固定机构包括薄钢板和两组压紧工具；张拉机构包括张拉固定座、反力块、千斤顶、圆轴、丝杆和压板；千斤顶连接在张拉固定座与反力块之间，在张拉固定座上设置张拉行程槽，圆轴设置在张拉行程槽内，圆轴与反力块通过丝杆连接；在张拉固定座的一侧设置压板，压板通过支架与张拉固定座连接；在压板与张拉固定座之间设置压条；纤维布的一端压在薄钢板与桥梁之间，并由压紧工具压住纤维布，纤维布经过压板、压条后绕过圆轴，另一端再经过压条和压板。纤维布在张拉过程中，避免出现崩坏、滑移现象。
