Flange device for fixing structural flat plate in impact resistance test

The invention discloses a flange device for fixing a structural flat plate in an impact resistance test, the flange device comprises a support frame, a flange structure and a counterweight structure, the flange structure is detachably connected with the support frame, and the flange structure is used for applying pressure to the structural flat plate, so that the structural flat plate is fixed on the support frame; the supporting frame is connected with the balance weight structure. The flange device is detachably arranged on the supporting frame through the flange structure, the structural flat plate is fixedly pressed, damage to the structural flat plate is reduced, the supporting frame is borne through the balance weight structure, when the flange device is lifted, the balance weight structure can play a balance weight role, and the stability of the flange device is improved. The method can be widely applied to the technical field of constructional engineering. 本申请公开了一种抗冲击试验固定结构平板的法兰装置，法兰装置包括支撑架、法兰结构和配重结构，
