FRP cloth prestress reinforcing device and construction method thereof
The invention discloses an FRP cloth pre-stress reinforcing device and a construction method thereof.The FRP cloth pre-stress reinforcing device comprises FRP cloth and a winding tensioning piece for winding of the FRP cloth, the two ends of the FRP cloth are provided with bonding anchoring areas for connecting structural members respectively, and the winding tensioning piece is located between the two bonding anchoring areas; the winding and tensioning piece is rotatably installed on the structural member, the pre-stress applied to the FRP cloth is changed when the angle of the winding and tensioning piece is adjusted, the two ends of the FRP cloth can be pasted and anchored firstly, then tensioning is conducted, an original member does not need to be holed or welded, operation is convenient, cost is low, the structure is especially suitable for steel members which are not suitable for holing, and the application range is wide. According to the method, the FRP cloth is subjected to winding pre-tightening and rotary tensioning through the specially-designed winding tensioning piece capable of being installed later, tensioning and prestress control and adjustment of the FRP cloth are achieved, the method is efficient and labor-saving, special mechanical equipment is not needed, the extension stroke of the end of the FRP is amplified, and the method has high popularization value.
本发明公开了一种FRP布预应力加固装置及其施工方法，FRP布预应力加固装置包括FRP布和供所述FRP布缠绕的缠绕张拉件，所述FRP布的两端分别设有供连接结构构件的粘结锚固区，所述缠绕张拉件位于两个所述粘结锚固区之间，通过将所述缠绕张拉件可转动地安装于所述结构构件，在调节所述缠绕张拉件的角度时改变对所述FRP布的预加预应力，本发明可先对FRP布两端进行粘贴锚固，再张拉，无需对原构件开孔或焊接，操作方便、成本低，尤其适合不宜开孔的钢构件，通过特殊设计的可后装的缠绕张拉件，对FRP布进行缠绕预紧、旋转张拉，实现对FRP布的张拉、预应力控制及调节，该方法高效省力，无需特殊机械设备，对FRP端部的伸长行程进行放大，具有较高的推广价值。
