For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Such as Figures 1 - 5As shown in the figure, the utility model provides the following technical solution: a tensioning type steel bar binding formwork, which includes a chuck 2 slidably arranged on a lifting trolley. A plurality of guide rods 3 are slidably arranged through the chuck 2. The bottom ends of the guide rods 3 are fixedly connected to the top surface of the lifting trolley. A hydraulic cylinder 14 is fixedly connected between the chuck 2 and the lifting trolley. A plurality of positioning holes 4 are formed in the side wall of the chuck 2. A support plate 1 is slidably sleeved on the plurality of guide rods 3. A return spring 15 is fixedly sleeved on the guide rods 3. The other end of the return spring 15 is fixedly connected to the side wall of the support plate 1. A plurality of through holes 5 corresponding to the positioning holes 4 are formed in the side wall of the support plate 1. A plurality of cards 6 are slidably connected through the through holes 5 by a reset mechanism. The plurality of cards 6 are annularly arranged in the through holes 5. The outer diameter of the cards 6 gradually decreases along the direction close to the chuck 2. The output end of the hydraulic cylinder 14 can drive the positioning holes 4 to move through the chuck 2 and sleeve on the cards 6 and push them to move closer to each other.

[0025] Please refer to Figure 1 As shown in the figure, during the construction of the box girder steel bar cage binding, first, a plurality of steel bars to be bound are sequentially passed through the through holes 5 and the positioning holes 4. Then, operate the hydraulic station to make the hydraulic cylinder 14 work. The hydraulic cylinder 14 drives the chuck 2 to move gradually closer to the support plate 1. The chuck 2 drives the positioning holes 4 to move and gradually sleeve on the corresponding cards 6. The outer diameter of the cards 6 gradually decreases along the direction close to the chuck 2. The chuck 2 pushes the plurality of cards 6 to move to clamp and position the steel bars. After the steel bars are clamped and positioned, the hydraulic cylinder 14 pushes the chuck 2 to move. The chuck 2 drives the cards 6 to move. The cards 6 drive the support plate 1 to move and compress the return spring 15 to deform. The distance between the two chucks 2 becomes larger, thus realizing the straightening operation of the steel bars after positioning. Then, the steel bars are bound.

[0026] After the steel bars are bound, operate the hydraulic station again to make the output end of the hydraulic cylinder 14 contract. The output end of the hydraulic cylinder 14 drives the chuck 2 to move. The chuck 2 drives the through holes 5 to gradually slide off the cards 6. The return spring 15 pushes the support plate 1 to move back to its original position. The support plate 1 drives the cards 6 to move back to their original positions through the reset mechanism. Finally, move the lifting trolley away to cancel the support for the steel bars. During the positioning process, there is no need for workers to manually insert a plurality of cards into the positioning holes to position the steel bars, nor is it necessary to disassemble the cards, preventing the loss of the cards.

[0027] The diameter of the through holes 5 is larger than the minimum outer diameter of the cards 6 and smaller than the maximum outer diameter of the cards 6.

[0028] Please refer to Figure 1 As shown in the figure, during the use process, it is convenient for the chuck 2 to drive the through holes 5 to move and sleeve on the cards 6 and then push them to move.

[0029] Please refer to Figure 1 、 Figure 3As shown in the figure, an embodiment of a reset mechanism. The reset mechanism includes a plurality of chutes 8 annularly arranged on the surface of the support plate 1. The chutes 8 communicate with the through holes 5. A sliding rod 7 is slidably connected in the chutes 8. One end of the sliding rod 7 is fixedly connected to the support plate 1 by a first tension spring 9. The first tension spring 9 is arranged in the chutes 8. The other end of the sliding rod 7 is fixedly connected to the surface of the card 6.

[0030] Please refer to Figure 1 As shown in the figure, during the use process, when the chuck 2 drives the through hole 5 to move and sleeve on the card 6 and pushes the card 6 to move to clamp the steel bar, the card 6 drives the sliding rod 7 to move in the chute 8 and pulls the first tension spring 9 to deform.

[0031] When the chuck 2 drives the through hole 5 to move and separate from the card 6, at this time, the deformed first tension spring 9 pulls the sliding rod 7 to move, and the sliding rod 7 drives the card 6 to move back to its original position.

[0032] A groove 10 is formed on the inner arc surface of the card 6. A rubber plate 11 is slidably attached to the groove 10. A connecting rod 12 is fixedly connected to the surface of the rubber plate 11. One end of the connecting rod 12 passes through the card 6 and is slidably connected to it. A second tension spring 13 is fixedly connected between the rubber plate 11 and the card 6. The second tension spring 13 is arranged in the groove 10 and sleeved on the connecting rod 12. The cross-section of the end of the connecting rod 12 away from the rubber plate 11 is an arc surface. The connecting rod 12 is arranged between the support plate 1 and the chuck 2.

[0033] Please refer to Figure 1 As shown in the figure, during the use process, when the chuck 2 drives the through hole 5 to sleeve on the card 6, the chuck 2 continues to move. The chuck 2 drives the through hole 5 to move and pushes the connecting rod 12 to move. The connecting rod 12 drives the rubber plate 11 to move closer to the steel bar and press on the steel bar, increasing the friction with the steel bar and improving the stability of the steel bar positioning.

[0034] The end face of the rubber plate 11 away from the chute 8 is an arc surface and its arc surface is on the same arc surface as the inner arc surface of the card 6.

[0035] Please refer to Figure 4 As shown in the figure, during the use process, the contact surface with the steel bar surface is increased, thereby increasing the friction between the steel bar and the rubber plate 11.

[0036] The length of one end of the connecting rod 12 passing through the card 6 is less than the wall thickness of the rubber plate 11.

[0037] Please refer to Figure 4 As shown in the figure, during the use process, the connecting rod 12 pushes the rubber plate 11 to move and squeeze the steel bar, causing the rubber plate 11 to deform. When one end of the connecting rod 12 completely slides into the card 6, the other end of the connecting rod 12 will not contact the surface of the steel bar at this time, which is convenient for the sliding of the connecting rod 12.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
