FRP cross-wound spiral stirrup and manufacturing method thereof
The invention discloses an FRP cross-wound spiral stirrup and a manufacturing method thereof, and relates to the technical field of building materials and building structures. The FRP cross-wound spiral stirrup and the manufacturing method thereof aim to solve the problems that existing steel spiral stirrups are prone to corroding and insufficient in durability, and FRP spiral stirrups are difficult to manufacture, high in cost, prone to bending damage during molding, low in constraint efficiency and the like. The FRP cross-wound spiral stirrup comprises a stirrup body. The spatial shape of the stirrup body is a three-dimensional spiral body crossed with each other, and the sectional shape of the stirrup body is a rectangle with the width much larger than the thickness. The manufacturing method of the stirrup body comprises the steps of spirally winding a fiber-impregnated resin formed FRP strip to a designated position in one direction, reversely winding to a starting position, curingand demoulding. The stirrup is excellent in performance, easy to manufacture, convenient to construct and low in cost, and can be used for concrete members such as beams and columns.
本发明公开了一种FRP交叉缠绕螺旋箍筋及其制作方法，涉及建筑材料与建筑结构技术领域。为了解决现有钢螺旋箍筋易锈蚀、耐久性不足和FRP螺旋箍筋制作困难、成本较高且成型时易发生弯曲损伤、约束效率不高等问题。本发明包括箍筋体。箍筋体的空间形状为相互交叉的三维螺旋体，截面形状为宽度远大于厚度的矩形。箍筋体的制作方法为将纤维浸润树脂形成FRP条带沿一个方向螺旋缠绕至指定位置后，再反向缠绕至起始位置，然后固化、脱模。本发明所述箍筋性能优异、制作简单、施工方便、成本较低，可用于梁、柱等混凝土构件。
