DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 3 As shown, a typical embodiment of the present invention provides a steel bar positioning fixture, including a transverse steel bar positioning unit and a longitudinal steel bar positioning unit 1. The transverse steel bar positioning unit includes two bottom positioning components 2 and a lateral positioning component 3. The longitudinal steel bar positioning unit 1 is fixedly arranged at both ends of the bottom positioning component 2. The two bottom positioning components 2 are displaced laterally outward from the inside of the transverse steel bar so that the longitudinal steel bar positioning unit 1 positions the four longitudinal steel bars respectively on the inner sides of the four corners of the transverse steel bar.

[0020] The transverse reinforcement positioning unit is used to position the transverse reinforcement. During the reinforcement cage production process, the transverse reinforcements are simply placed on the transverse reinforcement positioning unit in sequence. The longitudinal reinforcement positioning unit 1 is used to position the longitudinal reinforcement. During the reinforcement cage production process, after the transverse reinforcements are placed, the longitudinal reinforcement is passed through all the transverse reinforcements and then moved to the outside of the transverse reinforcements through the two bottom positioning components 2. The bottom positioning components 2 drive the longitudinal reinforcement positioning unit 1 to move, pressing the four longitudinal reinforcements against the inside of the four corners of the transverse reinforcement to achieve the positioning of the longitudinal reinforcement.

[0021] The bottom positioning assembly 2 includes a bottom plate 2.1, a longitudinal positioning plate 2.2, a transverse slot 2.3 and a diagonal support plate 2.4. The longitudinal positioning plate 2.2 is vertically fixed to the top of the bottom plate 2.1, the transverse slot 2.3 is opened at the top of the longitudinal positioning plate 2.2, and the diagonal support plate 2.4 is arranged on both sides of the longitudinal plate, and the bottom of the diagonal support plate 2.4 is fixed to the bottom plate 2.1.

[0022] The two longitudinal positioning plates 2.2 are distributed in parallel in the transverse direction, the transverse slots 2.3 on the top of the two longitudinal positioning plates 2.2 are distributed in a one-to-one correspondence in the transverse direction, and the diagonal support plates 2.4 can improve the overall stability of the bottom positioning assembly 2.

[0023] The longitudinal steel bar positioning unit 1 includes a vertical pole 1.1, an upper baffle 1.2 and a lower baffle 1.3. The bottom end of the vertical pole 1.1 is installed at the end of the base plate 2.1, and the upper baffle 1.2 and the lower baffle 1.3 are installed at the top and bottom ends of the vertical pole 1.1 respectively. The upper baffle 1.2 is set so that the outer end is tilted downward by 45°, and the lower baffle 1.3 is set so that the outer end is tilted upward by 45°.

[0024] In the process of the bottom positioning component 2 moving laterally from the inside of the transverse steel bar, the vertical rod 1.1 is driven to move, and the vertical rod 1.1 drives the upper stop rod 1.2 and the lower stop rod 1.3 to move. During this process, the triangular area formed between the upper stop rod 1.2 and the lower stop rod 1.3 and the corner of the transverse steel bar is continuously reduced, and the longitudinal steel bar is continuously pushed closer to the inside of the corner of the transverse steel bar, and finally the longitudinal steel bar is pressed against the inside of the corner of the transverse steel bar, thereby realizing the positioning of the longitudinal steel bar.

[0025] The top of the diagonal support plate 2.4 is higher than the height of the transverse groove 2.3, and the height difference between the top of the diagonal support plate 2.4 and the bottom of the transverse groove 2.3 is higher than the sum of the outer diameters of the transverse and longitudinal steel bars.

[0026] Such arrangement enables the oblique side of the diagonal support plate 2.4 to cooperate with the lower stop bar 1.3 to form a "V"-shaped area open outward, which can improve the pushing effect and positioning effect of the longitudinal reinforcement below.

[0027] In a relatively specific embodiment, the angle between the oblique side of the diagonal brace plate 2.4 and the horizontal plane is greater than 45 degrees, ensuring that the bottom of the longitudinal reinforcement located below can contact the bottom edge of the transverse reinforcement.

[0028] The inner ends of the upper and lower retaining bars 1.2 and 1.3 extend from the top and bottom of the transverse reinforcement, respectively, and the outer ends of the upper and lower retaining bars 1.2 and 1.3 extend laterally from the transverse reinforcement. This arrangement enables the upper and lower retaining bars 1.2 and 1.3 to form a closed triangular area with the corners of the transverse reinforcement when applied to transverse reinforcements of different side lengths, thereby being suitable for positioning longitudinal reinforcement within transverse reinforcements of different side lengths.

[0029] The vertical rod 1.1 is L-shaped, and the horizontal end of the vertical rod 1.1 is mounted on the end of the longitudinal positioning plate 2.2 by mounting bolts. Such an arrangement makes the longitudinal steel bar positioning unit 1 and the bottom positioning assembly 2 detachable and installable, improving practicality.

[0030] The lateral positioning assembly 3 comprises a side plate 3.1, a transverse positioning plate 3.2 and a longitudinal slot 3.3. The transverse positioning plate 3.2 is vertically fixed to the inner side of the side plate 3.1, and the longitudinal slot 3.3 is provided at the inner end of the transverse positioning plate 3.2.

[0031] The base plate 4 is also included. The bottom plate 2.1 is slidably mounted on the upper surface of the base plate 4. The bottom ends of the side edges are fixedly mounted on the upper surface of the base plate 4. Adjustment bolts 5 are threadedly connected to both ends of the base plate 2.1, and the adjustment bolts 5 are rotatably mounted on the base plate 4. By rotating the adjustment screws, the displacement of the bottom positioning assembly 2 on the base plate 4 can be controlled.

[0032] The steel bar positioning fixture provided in this embodiment can be operated in the following manner and is used to position transverse and longitudinal steel bars when making a steel cage.

[0033] First, place both sides of the bottom edge of the transverse steel bar into the corresponding transverse slots 2.3 on the top of the two longitudinal positioning plates 2.2 respectively, and at the same time, make the side edges of the transverse steel bar enter the longitudinal slots 3.3 of the transverse positioning plates 3.2.

[0034] Then, first rotate the adjusting bolt 5 near the side panel 3.1. When a closed triangular area is formed between the upper baffle 1.2 and the top corner of the transverse reinforcement near the side panel 3.1, respectively place the two longitudinal reinforcements into the two triangular areas. Then, continue to rotate the adjusting bolt 5 near the side panel 3.1 so that the upper baffle 1.2 and the lower baffle 1.3 respectively press the two longitudinal reinforcements against the inner sides of the upper and lower corners of the transverse reinforcement near the side panel 3.1.

[0035] At this time, not only the positioning of the two longitudinal steel bars is achieved, but also the positioning and fixation of the transverse steel bars are achieved.

[0036] Afterwards, the adjusting bolt 5 on the side away from the side panel 3.1 is rotated to displace the bottom positioning assembly 2 on the side away from the side panel 3.1 toward the outside of the transverse reinforcement, so that the upper stop bar 1.2 and the lower stop bar 1.3 on the side away from the side panel 3.1 respectively form a triangular area between the upper and lower corners of the transverse reinforcement on the side away from the side panel 3.1, and the upper and lower longitudinal reinforcements away from the side are pressed against the inner side of the corner of the transverse reinforcement to achieve the positioning of the other two longitudinal reinforcements on the transverse reinforcement.

[0037] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
