Prestress FRP rib tensioning and anchoring device
The invention discloses a prestress FRP rib tensioning and anchoring device, and belongs to the technical field of building reinforcement. The prestress FRP rib tensioning and anchoring device comprises an outer cylinder barrel, an inner cylinder barrel, a piston barrel, an anchoring assembly and an anchoring ring, and the other end of the piston barrel can be connected with the outer cylinder barrel through a second nut after penetrating out of the inner cylinder barrel; the piston cylinder is pulled outwards, the piston cylinder drives the anchoring ring to move, clamping petals are pressed on an FRP rib through the action of a conical cavity, under the continuous action of the anchoring ring, the anchoring assembly is made to stretch and draw the FRP rib, and the piston cylinder is fixed through the second nut to achieve anchoring. According to the prestress FRP rib tensioning and anchoring device, the prestress FRP rib tensioning and anchoring device can be used for quickly tensioning the FRP rib in a building, and is convenient and reliable to use.
本发明公开了一种预应力FRP筋张拉锚固装置，属于建筑加固技术领域，包括外缸筒、内缸筒、活塞筒、锚固组件和锚固环，所述活塞筒的另一端穿出所述内缸筒后能够通过第二螺母与外缸筒连接；通过向外拉动所述活塞筒，所述活塞筒带动锚固环位移，通过锥形腔的作用将各夹紧瓣压紧于FRP筋，在锚固环的持续作用下，使得锚固组件对FRP筋实现张拉，通过第二螺母将活塞筒固定实现锚固。本发明装置可以用于建筑中FRP筋的快速张拉，使用方便可靠。
