Interlayer displacement angle measurement apparatus

The invention provides a device for measuring interlayer displacement angle, which includes: a transmission rod, a first-stage coaxial disc, a second-stage coaxial turntable and a rotating shaft angle sensor; the upper end of the transmission rod passes through the first fixing part and the upper beam connected, and can slide up and down relative to the first fixing piece; the lower end of the transmission rod is fixedly connected with the first-level coaxial disc; The second fixed part rotates; the second-level coaxial turntable and the rotating shaft type angle sensor are fixed on the beam of this layer; the diameter of the first-level coaxial disc is greater than the diameter of the second-level coaxial turntable; the second-level coaxial turntable The diameter is larger than the diameter of the shaft on the shaft-type angle sensor; the first-stage coaxial disc, the second-stage coaxial turntable and the shaft on the shaft-type angle sensor are all connected by belt transmission or gear transmission. The application of the invention can directly measure the interlayer displacement angle with high precision, and improve the measurement accuracy of the interlayer displacement angle.
