Connecting structure of FRP (Fiber Reinforce Plastic) pipe restrained seawater and sea sand recycled concrete curved arch and foundation
The invention discloses a connecting structure of an FRP pipe restrained seawater and sea sand recycled concrete curved arch and a foundation. A curved arch body comprises an FRP pipe, an FRP rib cages, FRP plates and FRP bolts. One end of the FRP pipe is obliquely inserted into a foundation body; the FRP pipe is filled with seawater and sea sand recycled concrete; the FRP rib cage comprises FRP ribs and FRP stirrups; the FRP ribs penetrate through the FRP plates; the FRP bolts are in threaded connection with the ends of the FRP ribs and abut against the outer sides, close to the ends of the FRP ribs, of the FRP plates. A plurality of FRP plates are arranged at the ends, extending into the foundation body, of the FRP ribs so as to increase connection between arch feet of the curved arch body and the foundation body, and limiting FRP bolts are arranged on the FRP plate on the outermost side so as to prevent the FRP ribs from being pulled out of the FRP plates. The anchoring performanceof the curved arch body and the foundation body is enhanced, various internal forces at arch feet can be effectively resisted, and the connecting performance of the curved arch body and the foundationbody is improved.
本发明公开了FRP管约束海水海砂再生混凝土曲拱与基础的连接结构，曲拱本体包括FRP管、FRP筋笼、FRP板和FRP栓；FRP管一端斜插入基础本体内部；FRP管内部灌装有海水海砂再生混凝土；FRP筋笼包括FRP筋条和FRP箍筋；FRP筋条穿过FRP板；FRP栓与FRP筋条的端头螺纹连接，且与靠近FRP筋条端头的FRP板的外侧顶紧。本发明的FRP筋条伸入基础本体的端部布置有多块FRP板以增大曲拱本体拱脚与基础本体的连接，最外侧的FRP板布置有限位的FRP栓以防止FRP筋条从FRP板中拔出；增强了曲拱本体与基础本体的锚固性能，可有效抵抗拱脚处的各种内力，提高了二者的连接性能。
