The upper ends of the two connecting blocks are fixedly connected to mounting sleeves, and the upper ends of the two mounting sleeves are penetrated with mounting holes, and the two mounting holes are rotatably connected with fixing bolts, and the diameter of the fixing bolts is equal to the inner diameter of the mounting holes. The upper end of the base plate is penetrated with two first connecting holes, and the two first connecting holes are jointly fixedly installed with a position adjustment component, and the front end of the position adjustment component is slidably installed with a spacing adjustment component. The steel bar positioning structure for construction described in the utility model can achieve the purpose of flexibly adjusting the steel bar installation position and improving construction efficiency by setting a position adjustment component; and can achieve the purpose of adjusting the spacing between two steel bars and conveniently and quickly positioning the steel bars for construction by setting a spacing adjustment component;

The nut 34 is manually controlled to rotate. When the nut 34 rotates, the movable plate 37 can be moved backward through the second threaded rod 32. When the movable plate 37 moves backward, the two extrusion blocks 36 can be driven to move backward.
