Device and method for detecting shear bearing capacity of connecting piece combined insulation board

The invention relates to the technical field of buildings, and discloses a device and a method for detecting the shear capacity of a connecting piece combined insulation board. The detection device comprises a detection sample, a loading frame and a universal testing machine, the detection sample comprises a concrete wall body, an insulation board, a connecting piece and a plastic film, the insulation board is arranged on the concrete wall body through the connecting piece, the plastic film is arranged between the insulation board and the concrete wall body, and the loading frame is clamped at the top end of the concrete wall body. According to the detection device and the detection method, the detection sample is placed on the universal testing machine, the universal testing machine applies vertical downward shearing force to the insulation board and the connecting piece until the insulation board and the connecting piece are damaged, and the universal testing machine records the loaded maximum stress value
