Prestress FRP sheet tensioning and reinforcing device and method
The invention discloses a prestress FRP sheet tensioning and reinforcing device and method.The prestress FRP sheet tensioning and reinforcing device comprises a first anchoring assembly and a second anchoring assembly which are both arranged on the reinforcing surface of a component and arranged in the length direction of the component in a spaced mode; the first tensioning assembly and the second tensioning assembly are both arranged on the reinforced surface, the first tensioning assembly is located on the side, away from the second anchoring assembly, of the first anchoring assembly, the second tensioning assembly is located on the side, away from the first anchoring assembly, of the second anchoring assembly, and the first tensioning assembly and the second tensioning assembly are used for fixing the two ends of the sheet correspondingly; wherein the first tensioning assembly and/or the second tensioning assembly can pre-stretch the sheet in the direction away from the length direction of the sheet through the driving part, and after the driving part is withdrawn, the pre-stretched first tensioning assembly and/or the pre-stretched second tensioning assembly can keep the pre-stretching force of the sheet. According to the invention, the FRP sheet is tensioned by prestress, the driving piece is withdrawn after the FRP sheet is tensioned, and the pre-tensioned state of the sheet is kept through the tensioning assembly.
本发明公开了一种预应力FRP片材张拉加固装置及方法，其中预应力FRP片材张拉加固装置包括：均设置于构件加固表面的第一锚固组件和第二锚固组件，两锚固组件沿构件的长度方向间隔设置；均设置于加固表面的第一张拉组件和第二张拉组件，第一张拉组件位于第一锚固组件远离第二锚固组件的一侧，第二张拉组件位于第二锚固组件远离第一锚固组件的一侧，二者用于分别固定片材两端；其中，第一张拉组件和/或第二张拉组件能够通过驱动件沿远离片材长度方向预拉伸片材，且在驱动件撤离后，预拉伸后的第一张拉组件和/或第二张拉组件能够保持片材的预拉伸力。本发明通过对FRP片材的预应力张拉，在拉伸后撤离驱动件，并通过张拉组件保持片材的预拉伸状态。
