Device and method for measuring bonding shearing strength of cast-in-place concrete and prefabricated concrete of superposition shearing wall

The invention discloses a device and method for measuring the bonding shearing strength of cast-in-place concrete and prefabricated concrete of a superposition shearing wall. The device comprises a base, a jack, a force sensor, an insulation electric wire, a steel accessory, flange plates, a bolt, cut-strip concrete and a load collector. The base is erected on the ground or a wall or a column or a counter-force frame, and the jack is erected on the base. One end of the force sensor is connected with the jack through a connecting piece, and the other end of the force sensor is connected with the steel accessory through a connecting piece. The insulation electric wire of the force sensor is connected with the load collector. A protruding part is arranged at one end of the steel accessory and is embedded into the cut-strip concrete in the superposition shearing wall. The device can really measure the bonding shearing strength of the cast-in-place concrete and the prefabricated concrete of the superposition shear
