Fabricated component mounting and positioning device based on BIM (Building Information Modeling) technology

The utility model discloses a BIM (Building Information Modeling) technology-based assembly type component mounting and positioning device which comprises a fixed seat, a movable seat capable of rotating around the center of the fixed seat is arranged above the fixed seat, and a locking mechanism for positioning the movable seat after the position of the movable seat is determined is arranged between the movable seat and the fixed seat. The installation positioning device comprises a movable seat, two guide holes which are parallel to each other are formed in the movable seat, guide rods are connected into the guide holes in a sliding mode, and one end of each guide rod is connected with a positioning plate arranged outside the movable seat. The positioning plate can have an angle swinging function, so that the positioning precision of the base during mounting can be reduced, even if the base is inclined after being mounted, the position of the positioning plate can be adjusted by rotating the angle of the po
