FRP (Fiber Reinforce Plastic) combined truss-web girder bridge node and manufacturing method thereof
The invention discloses an FRP combined truss-web girder bridge node which comprises FRP perforated plate shear connectors, FRP ribs and FRP truss web members, one end of each FRP perforated plate shear connector is provided with a through rib hole, the other end of each FRP perforated plate shear connector extends to form two access ends, the two FRP perforated plate shear connectors are oppositely arranged, the FRP truss web members are clamped and mounted at the two access ends of each FRP perforated plate shear connector, the FRP ribs penetrate through the through rib holes of the FRP perforated plate shear connectors, and the FRP ribs penetrate through the FRP truss web members. The top of one end of the FRP truss web member is provided with a hole arc-shaped positioning steel plate, a bolt penetrates through a mounting hole of the hole arc-shaped positioning steel plate and penetrates through the FRP truss web member, one end of the bolt is provided with a nut, and the two FRP perforated plate shear connectors and a cavity of the FRP truss web member are filled with concrete. All components forming the joint can be prefabricated and assembled and used on site, construction is convenient, and meanwhile the construction period is greatly shortened. Compared with a traditional steel joint, the joint is good in corrosion resistance and durability. The joint is good in elastic performance and has good anti-fatigue performance.
本发明公开了一种FRP组合桁腹梁桥节点，包括FRP开孔板剪力连接件、FRP筋、FRP桁腹杆，FRP开孔板剪力连接件的一端设有贯穿筋孔，另一端延伸出两个接入端，两块FRP开孔板剪力连接件相对布置，在其两个接入端夹紧安装有FRP桁腹杆，其贯穿筋孔内贯穿有FRP筋，FRP桁腹杆的一端顶部安装有孔弧形定位钢板，螺栓穿过孔弧形定位钢板的安装孔贯穿FRP桁腹杆，螺栓的一端装有螺帽，两块FRP开孔板剪力连接件以及FRP桁腹杆的空腔内灌满混凝土。组成节点的各个构件可预制完成，现场拼装使用，施工方便的同时，大大缩短工期。该节点相对于传统钢节点，耐腐蚀性能好，耐久性好。该节点弹性性能好，具有良好的抗疲劳性能。
