Description

Technical Field

[0001] This invention belongs to the technical field of rebar tying devices, specifically relating to a rebar tying device for building engineering. Background Technology

[0002] In construction engineering, the most important material is steel reinforcement. It not only accounts for the heaviest weight in a building, but it is also the most expensive. The weight of the entire building, including the weight of the building itself and external objects, is borne by steel reinforcement. It can be said that steel reinforcement is the "heart" of the entire building. In order to construct this "heart", tie wire is needed to bind the horizontal and vertical steel reinforcement. When tying steel reinforcement with tie wire, steel reinforcement binding device is used.

[0003] Chinese Patent CN109184223B discloses a multifunctional rebar tying device. This invention can complete tying operations over short distances as well as tying rebars at distant locations, improving the applicability of the entire device and enabling tying operations for rebars at different distances and locations to be tied.

[0004] When tying rebar, the binding wire is typically bent into a double strand from the middle, then bent again into a U-shape, with one end of the wire looping around the rebar connection point. The hook head then passes through the bent portion of the wire, with the side of the hook head contacting the other end of the wire. The hook is then rotated, causing the two ends of the wire to spirally intertwine. While the rebar tying device in the aforementioned comparative patent can tie rebar at varying distances, it is difficult for workers to properly attach the binding wire to the rebar connection point when the rebar is far from them and workers cannot directly approach. The existing rebar tying hooks require the tie wire at the rebar connection point to be pre-tied by the construction worker manually or with the aid of tools. The hook head is then connected to the tie wire and rotated to complete the tying. This makes it inconvenient to use when tying rebars that are difficult to access directly from a distance, as the tie wire needs to be pre-tied. Furthermore, existing rebar tying hooks typically require the construction worker to manually wrap the tie wire around the rebar connection point and connect it to the hook head, which is inconvenient for long-distance operation. Therefore, this paper proposes a rebar tying device for construction engineering to solve the above problems. Summary of the Invention

The square frame is movably disposed between two first connecting plates.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] See Figure 1 - Figure 5 As shown, a rebar tying device for building construction includes:

[0034] Handle 1, the surface of handle 1 is provided with anti-slip texture;

[0035] Rotating mechanism 2 is movably disposed on one side of handle 1 and includes mounting plate 21, guide plate 22, rotating plate 23 and first motor 24. Guide plate 22 is fixedly installed on one end of mounting plate 21 and is rotatably connected to rotating plate 23. First motor 24 is fixedly installed on the inner side of mounting plate 21 and its driving end passes through guide plate 22 and is fixedly connected to rotating plate 23.

[0036] Telescopic rod 3 is installed between handle 1 and rotating mechanism 2 to adjust the distance between handle 1 and rotating mechanism 2;

[0037] The binding mechanism 4 includes a first connecting plate 41, a first clamping component 42, a rotating component 43, a second connecting plate 44, and a second clamping component 45. The two first connecting plates 41 are symmetrically fixed on one side of the rotating plate 23. The first clamping component 42 is rotatably installed between the two first connecting plates 41. The rotating component 43 is used to rotate the first clamping component 42. The two second connecting plates 44 are symmetrically arranged on one side of the rotating plate 23. The second clamping component 45 is fixedly installed on the second connecting plate 44.

[0038] The wire binding body 5 is bent, and its bent end is clamped inside the first clamping member 42.

[0039] As can be seen from the above, during the rebar binding process, one end of the binding wire body 5 is first bent and hooked inside the first clamping component 42. Then, by adjusting the rotating component 43, it is ensured that the length direction of the binding wire body 5 is parallel to the first connecting plate 41. At this time, the handle 1 is held to insert the heads of the first connecting plate 41 and the second connecting plate 44 into the rebar cage from both sides of the cross-shaped connection position of the two rebars. Subsequently, the rotating component 43 is controlled to rotate, causing the binding wire body 5 to rotate 90 degrees. This causes the other end of the binding wire body 5 to move to the inside of the second clamping component 45. Then, the binding wire body 5 can be clamped and fixed by the second clamping component 45. Pull the device to bring the heads of the first connecting plate 41 and the second connecting plate 44 back to the outside of the rebar cage. At this time, both ends of the tie wire body 5 have moved to the outside of the rebar cage, and a part of the tie wire body 5 contacts and bends at the cross-shaped connection position of the two rebars from the inside of the rebar cage. Finally, control the rotating mechanism 2 to rotate, driving the first connecting plate 41 and the second connecting plate 44 to rotate. In this way, the two ends of the tie wire body 5 can be wound together, thus successfully completing the rebar binding operation. With the setting of the telescopic rod 3, the rebar binding device for construction engineering can flexibly adjust the distance of the binding rebar, further reducing the difficulty of binding the rebar and making the device more convenient to use.

[0040] Specifically, by Figure 3 , Figure 4 and Figure 5It is known that the first clamping component 42 includes a square frame 421, a rotating shaft 422, a sliding plate 423, and a second electric push rod 424. The square frame 421 is movably disposed between two first connecting plates 41. The two rotating shafts 422 are respectively fixedly installed at both ends of the square frame 421 and are rotatably connected to the first connecting plate 41 on the same side. The sliding plate 423 is slidably connected to the inner walls of both sides of the square frame 421. The second electric push rod 424 is fixedly installed on one side of the outer wall of the square frame 421, and its driving end penetrates into the interior of the square frame 421 and is fixedly connected to the sliding plate 423. An insert block 425 is fixedly installed at one end of the sliding plate 423. Two limiting blocks 426 are fixedly installed on one side of the inner wall of the square frame 421, and the insert block 425 is inserted between the two limiting blocks 426.

[0041] As can be seen from the above, the second electric push rod 424 can push the slide plate 423 close to the inner wall of the square frame 421, so that the insert 425 is inserted between the two limiting blocks 426. When the insert 425 is inserted between the two limiting blocks 426, the bent end of the tie wire body 5 is sleeved on the outside of the two limiting blocks 426 and will not fall off between the slide plate 423 and the inner wall of the square frame 421. After the binding is completed, the drive end of the second electric push rod 424 retracts to separate the device from the tie wire body 5.

[0042] Specifically, by Figure 3 and Figure 5 It can be seen that rubber pads 427 are fixedly connected to one end of the skateboard 423 and one side of the inner wall of the square frame 421.

[0043] As can be seen from the above, by setting the rubber pad 427, the wire tie body 5 can be fixed to prevent slippage and rotation when it is sleeved on the outside of the two limit blocks 426.

[0044] Specifically, by Figure 3 and Figure 4 It is known that the rotating component 43 includes a second motor 431, a driving gear 432 and a driven gear 433. The second motor 431 is fixedly installed on one side of the rotating plate 23, and its driving end passes through one of the first connecting plates 41 and is fixedly connected to the driving gear 432. The driven gear 433 is fixedly connected to one of the rotating shafts 422. The driving gear 432 and the driven gear 433 are connected by a toothed belt 434.

[0045] As can be seen from the above, the second motor 431 can drive the rotating shaft 422 to rotate, so that the square frame 421 can rotate accordingly.

[0046] Specifically, by Figure 3 and Figure 4It is known that the second clamping component 45 includes a third electric push rod 451 and a clamping plate 452. The two third electric push rods 451 are respectively fixed on the two second connecting plates 44, and their driving ends all pass through the second connecting plates 44 and are respectively fixedly connected to the clamping plate 452 on the same side. One end of the clamping plate 452 is fixedly installed with anti-slip clamping teeth 453.

[0047] As can be seen from the above, when the two third electric push rods 451 drive the clamping plate 452 to move simultaneously, they can clamp and fix the wire tie body 5 that has moved between the two clamping plates 452.

[0048] Example 2:

[0049] refer to Figure 2 , Figure 3 and Figure 4 As shown, the binding mechanism 4 also includes an elastic buffer component 46, which includes a first rotating seat 461, a second rotating seat 462, a fixed rod 463, and a tension spring 464. The first rotating seat 461 is fixedly installed on one side of the rotating plate 23 and is rotatably connected to the second connecting plate 44. The second rotating seat 462 is fixedly installed on one side of the rotating plate 23. The fixed rod 463 is fixedly installed between the two second connecting plates 44. The two ends of the tension spring 464 are rotatably connected to the second rotating seat 462 and the fixed rod 463, respectively.

[0050] As can be seen from the above, through the setting of the rotating base 461, the second connecting plate 44 can be guided to a position close to the first connecting plate 41. Due to the setting of the tension spring 464, the second connecting plate 44 and the first connecting plate 41 always remain relatively parallel without external force. When the first clamping component 42 and the second clamping component 45 respectively clamp the two ends of the tie wire body 5, and the tie wire body 5 is wrapped around the connection position of the two steel bars, by rotating the first connecting plate 41 and the second connecting plate 44, the two ends of the tie wire body 5 can be made to wrap around each other. In this process, the tension will pull the second connecting plate 44 closer to the first connecting plate 41. Due to the setting of the rotating base 461 and the tension spring 464, the first connecting plate 41, the second connecting plate 44 or the tie wire body 5 can be prevented from being pulled off when the tie wire body 5 is rotated.

[0051] Example 3:

[0052] refer to Figure 2 As shown, the telescopic rod 3 includes a first electric push rod 31 and a sleeve 32. The first electric push rod 31 is fixedly installed with the handle 1, and its drive end is fixedly connected to the mounting plate 21. The sleeve 32 is fixedly connected to the mounting plate 21, and its inner side is slidably connected to the outer side of the first electric push rod 31.

[0053] As can be seen from the above, by setting the first electric push rod 31, the distance of the tied steel bars can be adjusted.

[0054] Specifically, by Figure 2 It can be seen that a slider 25 is fixedly installed on one side of the guide plate 22, and an annular groove 26 that is slidably connected to the slider 25 is provided on one side of the rotating plate 23.

[0055] As can be seen from the above, by setting the slider 25 and the annular groove 26, the rotating plate 23 is made more stable when rotating.

[0056] Specifically, by Figure 2 It is known that the handle 1 is equipped with a PLC controller 11 and a battery 12 inside, and a switch 13 is provided on its outer side. The switch 13 controls the operation of the rotating mechanism 2, the telescopic rod 3, the first clamping component 42, the rotating component 43 and the second clamping component 45 through the PLC controller 11.

[0057] As can be seen from the above, by setting up the PLC controller 11 and the switch 13, the operation of the rotating mechanism 2, the telescopic rod 3, the first clamping component 42, the rotating component 43 and the second clamping component 45 can be controlled. The battery 12 can provide power to the electrical components in the device.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
