Device for detecting interlayer deformation performance of building curtain wall

The invention provides a device for detecting the interlayer deformation performance of a building curtain wall, and the device comprises a fixed frame, a plurality of installation columns, a fixed joist, a movable cross beam, a guide frame, an X-axis hydraulic oil cylinder, a Y-axis hydraulic oil cylinder and a Z-axis hydraulic oil cylinder, the fixed frame is provided with a plurality of installation columns, the fixed joist is transversely fixed on the installation columns, and the movable cross beam is fixed on the X-axis hydraulic oil cylinder. The bottom of each guide frame is fixed to the fixed joist, and the head and the tail of the movable cross beam are movably arranged in the corresponding guide frames in a penetrating mode. The lower portion of the movable cross beam is connected with the upper end of the fixed joist through a roller, and the movable cross beam horizontally moves along the fixed joist through the roller. The defect that a large lateral overturning moment exists under the action of
