FRP profile-steel profile groove tooth cementing connection joint and construction method
The invention discloses an FRP profile-steel profile groove tooth cementing connection joint and a construction method. The FRP profile-steel profile groove tooth cementing connection joint comprisesan FRP profile, a steel profile and an adhesive; grooves are machined in the steel profile in the length direction, protrusions are arranged in the grooves in the steel profile, long-strip-shaped protrusions corresponding to the grooves in the steel profile are arranged on the FRP profile, the long-strip-shaped protrusions on the FRP profile comprise basic protrusions and large protrusions, the steel profile and the FRP profile are in horizontal lap joint, the positions and sizes of the basic protrusion and the large protrusions are calculated and determined by calculating the size of the grooves in the steel profile and the thickness of an adhesive layer, the long-strip-shaped protrusions on the FRP profile are embedded into the grooves of the steel profile, and the space between the FRPprofile and the steel profile is filled with the adhesive. According to the FRP profile-steel profile groove tooth cementing connection joint, the joint connection efficiency is improved, the bottleneck problem of an FRP profile connection joint is solved, the construction is simple, and the FRP profile-steel profile groove tooth cementing connection joint can be applied to reinforcement of a newly-built FRP profile structure and an existing steel structure.
本发明公开了FRP型材‑钢型材槽齿胶结连接节点及施工方法，包括FRP型材、钢型材和胶粘剂；所述钢型材上沿长度方向加工凹槽，且钢型材上的凹槽内设置有凸起，FRP型材上设置与钢型材上凹槽对应的长条凸起，FRP型材上长条凸起包括基本凸起和大凸起，将钢型材与FRP型材水平搭接，基本凸起和大凸起的位置和尺寸，须通过钢型材上凹槽尺寸和胶层厚度计算计算确定，FRP型材上的长条凸起嵌入到钢型材的凹槽内，FRP型材和钢型材之间填充有胶粘剂。本发明FRP型材‑钢型材槽齿胶结连接节点提高了节点连接效率，解决FRP型材的连接节点这一瓶颈问题，且施工简单，可在新建FRP型材结构和既有钢结构加固中的得到应用。
