一种FRP管混凝土薄壁箱形截面构件
摘要：
本发明涉及一种FRP管混凝土薄壁箱形截面构件，属于钢管混凝土构件，它包括FRP管和薄壁FRP板，还包括混凝土，FRP管和薄壁FRP板组成薄壁箱形截面，FRP管位于薄壁箱形截面转角处，FRP管和薄壁箱形截面分隔成的封闭空间内填充混凝土形成FRP管‑混凝土组合部件和钢管混凝土部件，FRP管和薄壁钢板通过环氧树脂粘接在一起。本发明的构件将FRP管设置于整个截面的转角处，有效的避免了方钢管混凝土中的方钢管转角处存在严重的残余应力问题，还可提高此类构件的耐腐蚀性能。FRP管内填充混凝土形成FRP管‑混凝土组合部件，可充分发挥混凝土与FRP管之间组合效应。
摘要（英）：

The invention relates to an FRP pipe concrete thin-wall box-shaped section component and belongs to a steel pipe concrete component. The FRP pipe concrete thin-wall box-shaped section component comprises FRP pipes, thin-wall FRP plates and concrete. The FRP pipes and the thin-wall FRP plates form a thin-wall box-shaped section, the FRP pipes are located at the corners of the thin-wall box-shaped section, the enclosed spaces formed through division of the FRP pipes and the thin-wall box-shaped section are filled with the concrete to form FRP pipe-concrete combined parts and a steel pipe concrete part, and the FRP pipes and thin-wall steel plates are adhered together through epoxy resin. According to the component, the FRP pipes are arranged at the corners of the whole section, the problem that serious residual stress exists at the corners of square steel pipes in square steel pipe concrete is effectively solved, and anti-corrosion performance of the kind of components can be further improved. The FRP pipes are filled with the concrete to form the FRP pipe-concrete combined parts, and thus the combined effect between the concrete and the FRP pipes can be given into full play.
