FRP-concrete interface adhesive property double-shear experimental device based on universal testing machine

The utility model discloses an FRP-concrete interface adhesive property double-shear experimental device based on a universal testing machine. The FRP-concrete interface adhesive property double-shear experimental device comprises an upper structure, a lower structure, a suspension structure and a fixing structure, wherein the upper structure and the lower structure are connected with the universal testing machine; the suspension structure is used for suspending FRP; the upper structure and the lower structure respectively comprise a connector and a bolt hole which are connected with a universal testing machine. During installation, the upper structure and the lower structure are connected with a universal testing machine only through two bolts, and only six bolts and a test piece (concrete test piece) need to be assembled and disassembled during each test period. The positions of the upper structure and the hanging structure are fixed, and the fixing structure is connected with the lower structure through bo
