Winding forming FRP combined stirrup concrete structure
The invention discloses a winding formed FRP (Fiber Reinforced Plastic) combined stirrup concrete structure which is characterized by comprising an FRP winding wire, the FRP winding wire is a single-strand FRP infiltration resin fiber winding wire, various resins can be used, and the fiber content reaches 65% or above; the novel closed FRP stirrup is prepared by using a mechanical and automatic winding process, and can be integrally wound, tensioned and formed. Winding parameters of the FRP stirrup are controllable, fibers on the inner side are not curled, the FRP stirrup can be cut into closed FRP stirrups with the specified width-thickness ratio after winding, curing and demolding, and the closed FRP stirrups can be divided into circular closed FRP stirrups, square closed FRP stirrups and the like according to forms. Compared with a traditional stirrup, the stirrup has high strength, corrosion resistance and durability. In addition, the preparation process greatly reduces the preparation flow and lowers the cost.
本发明公开了一种缠绕成型FRP组合箍筋混凝土结构，其特征在于：包括FRP缠绕丝，所述FRP缠绕丝为单股FRP浸润树脂纤维缠绕丝，可使用树脂多样，纤维含量达65％以上；利用机械化和自动化缠绕工艺制备，所述新型封闭FRP箍筋可一体化缠绕张紧成型。所述FRP箍筋缠绕参数可控，内侧纤维无蜷曲，缠绕固化脱模后可切割成指定宽厚比的封闭FRP箍筋，按形态可分为圆形封闭FRP箍筋和方形封闭FRP箍筋等。本发明对比传统箍筋具有较高的强度，耐腐蚀性和耐久性。此外，制备工艺大幅减少制备流程，降低成本。
