Frame column steel bar positioning device and manufacturing method and using method thereof

The invention relates to the technical field of building construction auxiliary equipment, and provides a frame column steel bar positioning device which comprises four connecting rods with L-shaped sections, two first strip holes are formed in the first side face of each connecting rod in the length direction, and more than six second strip holes are formed in the second side face of each connecting rod at equal intervals in the length direction. The connecting rods are sequentially connected to form a frame body, the first side faces of every two adjacent connecting rods abut against each other, and the second side faces of every two adjacent connecting rods face opposite directions. The first fastener penetrates through the first strip holes of the two adjacent connecting rods to fixedly connect the two adjacent connecting rods together; and the second fastening piece is arranged on the second strip hole and can slide and be fixed along the length direction of the second strip hole.
