Positioning grooves 11 are provided on both sides of the positioning frame 1, and positioning grooves 12 are provided on the other two sides of the positioning frame 1. The two opposing positioning grooves 11 are shallower than the two opposing positioning grooves 12. By setting positioning grooves around the positioning frame 1, a clear locking space can be provided for the reinforcing mesh, and displacement can be prevented during welding, ensuring that the mesh is installed quickly and accurately. The screw 491 set in the positioning groove 11 is shorter than the screw 491 set in the positioning groove 12. An upper reinforcing bar 3 is placed between the two positioning grooves 11, and a lower reinforcing bar 2 is placed between the two positioning grooves 12. The lower reinforcing bar 2 is located below the upper reinforcing bar 3. A reinforcing bar fixing structure 4 is installed on the top side of both the positioning grooves 11 and 12.

[0028] like Figure 3 and Figure 4As shown, the steel reinforcement fixing structure 4 includes an arc-shaped support plate 41. One end of the arc-shaped support plate 41 is mounted on the upper end of the positioning frame 1 via a hinge and is located on one side of the positioning groove 11 or the positioning groove 12. The other end of the arc-shaped support plate 41 is fixedly connected to an L-shaped clamping plate 42. A circular groove 44 is opened in the middle of the outer side of the L-shaped clamping plate 42. A magnet 441 is arranged inside the circular groove 44. A magnet 48 is arranged in the middle of the other side of the connecting plate 46. The magnet 48 is arranged opposite to the magnet 441. When the insertion rod 45 is inserted between insertion hole 13 and insertion hole 2 43, magnet 2 48 is located on the outside of the circular groove 44, and magnet 2 48 is magnetically attracted to magnet 1 441. The magnetic attraction between magnet 2 48 and magnet 1 441 can fix the insertion rod 45 inserted between insertion hole 13 and insertion hole 2 43, preventing it from sliding off. Insertion hole 2 43 is provided on the front and back sides of the outer side of L-shaped card plate 42. Insertion hole 2 43 is provided around the positioning frame 1 and next to positioning groove 11 or positioning groove 2 12. Insert rods 45 are inserted into both insertion hole 13 and insertion hole 43.

A screw rod is provided at the upper end of the screw rod 491. Button 492, through the screw 491, knob 492 and arc-shaped fixing plate 493, provides clamping force by driving screw 491 to ensure the stability of the steel mesh fixing. The screw 491 drives the arc-shaped fixing plate 493 to move linearly, without the need for strict alignment, and can be operated with one hand, improving the efficiency of steel mesh fixing. In addition, the insertion rod 45 can lock the arc-shaped support plate 493 through insertion hole 13 and insertion hole 2 43, which facilitates the quick removal of the steel mesh after welding.

[0029] This utility model provides a positioning and fixing structure for steel mesh. The specific working principle is as follows: The positioning frame 1 is placed at the node of the steel mesh, with the lower steel bar 2 located between the second positioning groove 12 and the upper steel bar 3 located between the first positioning groove 11. Then, the arc-shaped support plate 41 is rotated so that the L-shaped clamping plate 42 is clamped at the edge of the positioning frame 1, and the second insertion hole 43 is aligned with the first insertion hole 13. The user pinches the pull ring 47 and inserts the insertion rod 45 between the second insertion hole 43 and the first insertion hole 13. After insertion, the second magnet 48 enters the circular groove 44 and magnetically attracts the first magnet 441. Then, the user rotates the knob 492 to drive the screw 491 to rotate, so that the arc-shaped fixing plate 493 presses the steel mesh. After welding, the user pinches the pull ring 47 to pull out the insertion rod 45, and rotates the arc-shaped support plate 41 to make the structure detach from the steel mesh.
