Tensioning and anchoring device for FRP cloth prestress reinforcing pipe joint and reinforcing method of tensioning and anchoring device
The invention discloses an FRP cloth prestress reinforcing pipe joint tensioning and anchoring device and a reinforcing method thereof.The FRP cloth prestress reinforcing pipe joint tensioning and anchoring device comprises a counter-force hoop, the pipe joint comprises a main pipe joint and a branch pipe joint, one end of the branch pipe joint is connected to one side of the main pipe joint, and the branch pipe joint is sleeved with the counter-force hoop; the movable hoop is movably arranged outside the branch pipe joint in a sleeving mode and arranged on the side, away from the main pipe joint, of the counter-force hoop, anchor boxes are installed on the two opposite sides of the movable hoop correspondingly, anchoring shafts are embedded in the anchor boxes, and penetrating holes are formed in the bottoms of the anchor boxes; the middle of the FRP cloth is supported on the other side of the main pipe joint, and the two ends of the FRP cloth penetrate through the penetrating holes respectively and are wound around the anchoring shafts; and the jacking and stretching assembly is used for jacking and pushing the movable hoop to stretch and draw the FRP cloth and is installed on the counter-force hoop, a locking piece is installed on the movable hoop, and after the FRP cloth is stretched and drawn, the locking piece locks the branch pipe joint. The problem that a tensioning anchoring device cannot be directly used due to the fact that the geometrical shape of the pipe joint is complex is solved.
本发明公开了一种FRP布预应力加固管节点张拉锚固装置及其加固方法，包括：反力环箍，管节点包括主管节和支管节，支管节的一端连接于主管节的一侧，反力环箍套设于支管节的外部；移动环箍，可活动地套设于支管节的外部且设置于反力环箍的远离主管节的一侧，移动环箍的相对两侧分别安装有锚箱，锚箱中嵌设有锚定轴，锚箱的底部形成有穿孔；FRP布，FRP布的中部承托于主管节的另一侧，FRP布的两端分别穿过穿孔并卷绕于锚定轴；用于顶推移动环箍以张拉FRP布的顶伸组件，安装于反力环箍，移动环箍上安装有锁定件，在FRP布张拉后，锁定件锁定支管节。本发明解决了管节点的几何形状复杂无法直接使用张拉锚固装置的问题。
