Steel ball rolling type steering device of external prestress FRP rib and manufacturing method of steel ball rolling type steering device
The invention discloses a steel ball rolling type steering device of an external prestress FRP rib and a manufacturing method of the steel ball rolling type steering device, and relates to the technical field of FRP rib newly-built structures and reinforcement. According to the technical scheme, the steel ball rolling type steering device comprises an inner side plate, an outer side plate, a steering curved plate and a curved surface base plate; the steering curved plate is located between the inner side plate and the outer side plate, and the side faces of the two sides of the steering curved plate are fixed to the inner surface of the inner side plate and the inner surface of the outer side plate respectively. The curved surface base plate is located between the inner side plate and the outer side plate, the curved surface base plate is in sliding fit relative to the steering curved plate, and a plurality of balls are distributed between the steering curved plate and the curved surface base plate. The friction between the external FRP rib and the steering curved surface of the steering device is converted into rolling friction from sliding friction, so that the problem of sliding wear of a sliding steering device to the external FRP rib can be well solved, and the FRP rib in a steering area is prevented from being broken and failed in advance under the combined action of wear and stress; therefore, the safety and durability of the external prestress FRP rib structure are improved.
本发明公开了体外预应力FRP筋的钢珠滚动型转向装置及其制作方法，涉及FRP筋新建结构及加固技术领域，本发明的技术方案包括内侧板、外侧板、转向曲面板和曲面垫板；所述转向曲面板位于所述内侧板和外侧板之间，所述转向曲面板的两侧侧面分别与所述内侧板和外侧板的内表面固定；所述曲面垫板位于所述内侧板和外侧板之间，所述曲面垫板相对所述转向曲面板滑动配合，所述转向曲面板与所述曲面垫板之间分布有若干滚珠。将体外FRP筋与转向装置转向曲面之间的摩擦由滑动摩擦转变为滚动摩擦，可以较好地解决滑动型转向装置对体外FRP筋的滑动磨损问题，避免转向区域FRP筋在磨损和受力的共同作用下提前破断失效，从而提高体外预应力FRP筋结构的安全性和耐久性。
