FRP-concrete composite beam shear connector
The invention discloses an FRP concrete composite beam shear connector which comprises an FRP perforated plate, an FRP I-shaped beam, perforated steel bars and concrete. The concrete is poured above the FRP I-shaped beam, the upper surface of the FRP I-shaped beam is connected with a bottom plate of the FRP perforated plate through a plurality of bolts and epoxy resin glue, the multiple perforatedsteel bars are inserted into a connecting plate of the FRP perforated plate in a penetrating mode, and the FRP perforated plate, the perforated steel bars and the upper ends of the bolts are all located in the concrete. The FRP perforated plate and an FRP main beam are connected in a mixed mode through the glue and the bolts, the bolts extend into the concrete, the bolts connect the perforated plate and the main beam and bear interface shear force at the same time, shear bearing capacity and lifting resistance can be enhanced, construction is simple, and quality is reliable.
本发明公开了一种FRP‑混凝土组合梁剪力连接件，包括FRP开孔板、FRP工字梁、穿孔钢筋和混凝土。FRP工字梁的上方浇筑有混凝土，FRP工字梁的上表面采用若干螺栓和环氧树脂胶与FRP开孔板的底板连接，FRP开孔板的连接板上穿插有若干穿孔钢筋，FRP开孔板、穿孔钢筋和若干螺栓的上端均位于混凝土内。本发明的FRP开孔板与FRP主梁通过胶栓混合连接，将螺栓伸入混凝土中，螺栓连接开孔板与主梁的同时承担界面剪力，可增强抗剪承载力与抗掀起力，且施工简单质量可靠。
