[0002] As we all know, rebar refers to the steel used in reinforced concrete and prestressed concrete. Before use, rebar is processed in a factory into a suitable structural framework based on the actual situation. This is done by bending the rebar into a specific shape using a machine. Stirrups are then used to secure the multiple bars together, and the stirrups are tied to the rebar with wire.

[0003] An existing steel bar positioning device for civil engineering (Announcement No.: CN220747438U) has at least the following disadvantages: in the above patent, when connecting the steel bars and stirrups, the steel bars need to be placed inside the positioning groove for support, and then a number of hoop steel bars are distributed outside the steel bars and then connected with wire. However, the manual operation of positioning the several hoop steel bars one by one makes the operation more troublesome. At the same time, when positioning the steel bars, the support plates need to be adjusted one by one, which makes the positioning speed of the steel bars slow, inconvenient to use, and has certain limitations.

[0025] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0026] Through the support base plate 1, when the user needs to connect the steel bar 2 and the stirrup 19 so that the steel bar 2 and the stirrup 19 form a frame, the user manually rotates the threaded rod 6. The threads of the threaded rod 6 are symmetrically arranged, and the rotating threaded rod 6 and the threaded hole on the top surface of the movable plate 4 convert the rotational motion into a linear motion, so that the movable plate 4 moves up and down inside the supporting side plate 3, so that the two movable plates 4 move in opposite or similar directions, and then the distance between the two movable plates 4 is adjusted, and then the rotating crank 25 drives the first threaded column 11 to rotate inside the limiting hole 8 and the first fixing hole 7, and the first threaded column 11 is limited by the provided limiting hole 8 so that it will not move laterally, so that the first threaded column 11 and the first threaded hole 10 convert the rotational motion into a linear motion. The movable plate 4 is transformed into a linear motion, so that the two guide plates 9 move oppositely or similarly inside the movable plate 4 (the threads of the first threaded column 11 are symmetrically distributed starting from the middle), thereby completing the height and horizontal position adjustment of the guide plate 9. After that, the user manually pushes the movable frame 21 to move, and arranges a number of stirrups 19 on the top surface of the movable frame 21. The stirrups 19 are supported by the movable frame 21. The user divides the four steel bars into two groups, and each group of steel bars 2 passes through the two rotating columns 16 up and down, passes through the inside of the guide plate 9, and finally passes through the inside of the stirrups 19. The second threaded column 27 is rotated to move downward to press the top surface of the limit plate 14, driving the rotating column 16 to squeeze the steel bar, and the driving motor 18 is started to drive the rotating column 16 to rotate, so that the rotating column 16 rotates and drives the steel bar 2 to move. As a result, the user manually moves the stirrup 19, connects it with several steel bars 2, and ties the stirrup 19 and the steel bar 2 with the tying wire, thereby connecting the entire steel bar 2 and the stirrup 19 together to form a frame, and supports the tied steel bar 2 and stirrup 19 through the provided rotating roller 24, so that the frame The frame moves smoothly, thereby comprehensively achieving the effect of positioning the supporting base plate 1 and the steel bars 2. By moving a number of guide plates 9 up and down and laterally (the steel bars 2 pass through the guide plates 9), the size of the frame composed of the steel bars 2 can be adjusted. It is only necessary to rotate the threaded rod 6 and the crank 25. The operation is relatively convenient and the positioning speed is relatively fast. The rotating column 16 is driven to move the steel bars 2, which is convenient for users to connect the stirrups 19 to the steel bars 2 one by one. There is no need to manually position the stirrups 19 one by one and then connect them, which is convenient for users to perform bundling operations and is more practical.
