Cast-in-place concrete deformation measuring system and measuring method thereof

The invention discloses a cast-in-place concrete deformation measuring system and a measuring method thereof. The cast-in-place concrete deformation measuring system is mainly composed of a range finding device, a baffle plate device and a checking ruler device, wherein the range finding device comprises a laser range finder, a range finding box, a first adjusting rod and a second adjusting rod, and is mainly used for emitting a laser ray and adjusting reflection height and angle of the laser ray; the baffle plate device comprises a laser reflection plate, an adjusting base and a third adjusting rod, and is mainly used for reflecting the laser ray emitted by the range finding device and adjusting a position of a reflection center; and the checking ruler device comprises a checking ruler body and a ruler support, and is mainly used for checking and correcting vertical perpendicularity and horizontal perpendicularity of the baffle plate device, and ensuring that a laser ray emitted by the range finding device can just hit the reflection center of the baffle plate device and is positioned at the same horizontal height as the baffle plate device and kept perpendicular to the same. Therefore, the precision and reliability of concrete structural deformation measurement are effectively improved.
