Description
Technical Field
[0001] This utility model relates to the field of building construction, specifically to a rebar alignment and welding device for building construction. Background Technology
[0002] When performing single rebar extension welding, the primary requirement is to forcibly straighten the two rebars to be connected until they are parallel to each other, ensuring the stability of the overall structure after welding. Currently, this step still relies heavily on manual labor: operators must apply external force to the misaligned rebars by hand, repeatedly bending and adjusting them to precisely align the ends, and then temporarily bind and fix them with wire or clamps. The entire process not only consumes a lot of physical strength, but also, due to the constraint force of the rebars' own weight, the straightening and fixing are extremely difficult, severely restricting the efficiency of the welding operation.
[0003] From the perspective of current technological applications, the auxiliary tools used for this type of rebar splicing are mostly simple manual clamps or pry bars, lacking specialized devices for straightening and fixing vertical rebars. During manual binding, it is difficult to ensure that the two rebars maintain a strictly parallel butt joint, which can easily lead to problems such as end misalignment and axial displacement, resulting in unstable welding quality and even requiring rework. Utility Model Content
[0004] The purpose of this utility model is to provide a rebar alignment and welding device for building construction, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, a rebar alignment and welding device for building construction is provided, comprising an alignment frame, a straightening seat inside the alignment frame, and a connecting cylinder fixed to its end, a lead screw on the straightening seat, and an operating rod fixed to the lead screw through the top wall of the alignment frame, a force-bearing ball fixed to the end of the operating rod, an adjusting column inserted inside the connecting cylinder, and a threaded column fixed to the outer side of the end of the adjusting column.
[0006] Preferably, the alignment frame is U-shaped, and a screw hole is provided at the end of the alignment frame. A lead screw is screwed into the screw hole, and the lead screw and the operating rod are distributed in a T-shape.
[0007] Preferably, the straightening seat is C-shaped, and a guide seat is fixed on the back of the straightening seat. Two sets of guide rods are inserted inside the guide seat, and the guide rods are fixed on the inner wall of the alignment frame.
[0008] Preferably, the outer side of the connecting cylinder is provided with an adjustment track, and the connecting cylinder and the adjustment column are in a concentric circle structure, with a screw thread inserted inside the adjustment track.
[0009] Preferably, the screw-in post passes through the adjustment track and is screwed with an adjustment nut, and the depth of the adjustment post inserted inside the connecting cylinder is adjusted and fixed by the adjustment track, the screw-in post, and the adjustment nut.
[0010] Preferably, the end of the adjusting column is provided with a fixing seat, and a retaining seat is fixed on the fixing seat, the retaining seat being arc-shaped.
[0011] Preferably, the inner wall of the card holder is provided with a magnetic seat, and the magnetic seat is arc-shaped, and the magnetic seat is attached to the outside of the steel bar.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution uses a "C"-shaped straightening seat to apply uniform pressure to the internal misaligned reinforcing bars during the movement process, gradually straightening the two reinforcing bars until they are parallel to each other. If fine adjustment of the straightening force is required, the operating rod can be rotated in the opposite direction to drive the lead screw and the straightening seat to return to their original position until the reinforcing bars achieve the ideal parallel accuracy and meet the welding stability requirements. 2. This solution uses a straightening seat that moves directionally along a guide rod via a guide seat. The "T"-shaped structure of the lead screw and operating rod can transmit the straightening force at a uniform speed, making the pressure applied to the reinforcing bar by the "C"-shaped straightening seat more uniform. This allows the reinforcing bar to be accurately straightened into a parallel butt joint state, avoiding welding quality problems caused by manual operation errors. No manual binding is required during welding, and there will be no problems such as misalignment or axis deviation. Attached Figure Description

[0015] Please see Figure 1-5This utility model provides a rebar alignment and welding device for building construction, including an alignment frame 1. The alignment frame 1 is provided with a straightening seat 11 inside, and a connecting cylinder 2 is fixedly connected to its end. A lead screw 12 is provided on the straightening seat 11, and an operating rod 13 is fixed through the top wall of the alignment frame 1. A force-receiving ball 14 is fixed at the end of the operating rod 13. An adjusting column 21 is inserted inside the connecting cylinder 2, and a screw thread 22 is fixed to the outer side of the end of the adjusting column 21.
[0016] In a preferred embodiment, the alignment frame 1 is U-shaped, and a screw hole is provided at the end of the alignment frame 1. A lead screw 12 is screwed into the screw hole, and the lead screw 12 and the operating rod 13 are distributed in a T-shape.
[0017] The straightening seat 11 is C-shaped, and a guide seat 110 is fixed on the back of the straightening seat 11. Two sets of guide rods 15 are inserted inside the guide seat 110, and the guide rods 15 are fixed on the inner wall of the alignment frame 1.
[0018] Working Principle: The alignment frame 1 serves as the core operating platform. Its "U"-shaped structure allows for easy placement on the outside of the reinforcing bars to be joined, providing a stable framework for subsequent straightening operations. An adjusting column 21 is inserted inside the connecting cylinder 2 at the end of the alignment frame 1. Operators can initially adjust the relative position of the alignment frame 1 and the reinforcing bars by adjusting the insertion depth of the adjusting column 21 within the connecting cylinder 2. Then, using the screw-in column 22 on the outside of the adjusting column 21, the adjusting column 21 is screwed and locked to the connecting cylinder 2, ensuring that the alignment frame 1 does not shift during operation, thus laying the foundation for straightening. The two misaligned reinforcing bars to be joined are placed inside the straightening seat 11 within the alignment frame 1. Because the straightening seat 11 is "C"-shaped, it stably supports the reinforcing bars and restricts their lateral movement. At this time, the guide seat 110 on the back of the straightening seat 11 is fitted onto two sets of guide rods 15, which are fixed to the inner wall of the alignment frame 1, providing directional guidance for the vertical movement of the straightening seat 11 and preventing it from shifting. The operator rotates the operating lever 13. Because the operating lever 13 and the lead screw 12 are arranged in a "T" shape, rotating the operating lever 13 can drive the lead screw 12 to move up and down along the threaded hole. The force-receiving ball 14 at the end of the operating lever 13 can increase the force-receiving area of the hand, reduce the operating intensity, and make the rotation process more effortless. When the lead screw 12 moves downward, its bottom end will push the straightening seat 11 to move vertically downward along the guide rod 15. During the movement, the "C"-shaped straightening seat 11 applies uniform pressure to the internal misaligned reinforcing bars, gradually straightening the two reinforcing bars until they are parallel to each other. If it is necessary to fine-tune the straightening force, the operating lever 13 can be rotated in the opposite direction to drive the lead screw 12 and the straightening seat 11 to return to their original position until the reinforcing bars achieve the ideal parallel accuracy and meet the welding stability requirements. In a preferred embodiment, the outer side of the connecting cylinder 2 is provided with an adjusting track 211, and the connecting cylinder 2 and the adjusting column 21 are in a concentric circle structure, with a screw thread 22 inserted inside the adjusting track 211.
[0019] The screw-in pin 22 passes through the adjusting rail 211 and is screwed with the adjusting nut 23. The depth of the adjusting pin 21 inserted into the connecting cylinder 2 is adjusted and fixed by the adjusting rail 211, the screw-in pin 22 and the adjusting nut 23.
[0020] The end of the adjusting column 21 is provided with a fixed seat 24, and a card seat 25 is fixed on the fixed seat 24. The card seat 25 is arc-shaped.
[0021] The inner wall of the card holder 25 is provided with a magnetic seat 26, which is arc-shaped and is attached to the outside of the steel bar.
[0022] like Figure 1 As shown: The adjustment track 211 on the outside of the connecting cylinder 2 cooperates with the concentric circle structure of the connecting cylinder 2 and the adjustment column 21, making the insertion depth of the adjustment column 21 in the connecting cylinder 2 more flexible and precise. The operator can adjust the extension length of the adjustment column 21 by moving the screw column 22 along the adjustment track 211 according to the position of the vertical steel bar to be connected. After adjustment, tightening the adjustment nut 23 can fix it firmly, preventing the adjustment column 21 from shifting during operation and further improving the positioning accuracy of the alignment frame 1. The arc-shaped bracket 25 fixed on the fixing seat 24 at the end of the adjusting column 21 can better fit the outer contour of the steel bar, increase the contact area with the steel bar, and make the connection between the fixing seat 24 and the steel bar more stable. The arc-shaped magnetic seat 26 on the inner wall of the bracket 25 can be directly attached to the outside of the steel bar without the need for additional tools to bind it, which can quickly achieve temporary fixation of the adjusting column 21 and the steel bar, simplify the initial positioning operation steps and save time. Meanwhile, the magnetic suction seat 26 can also enhance the connection strength between the card holder 25 and the reinforcing bar, prevent the alignment frame 1 from shifting due to force during the straightening operation, ensure the stability of the straightening seat 11 when applying pressure to the reinforcing bar, and thus ensure the parallel accuracy of the butt joint after the reinforcing bar is straightened, providing a more reliable guarantee for the subsequent welding quality. Moreover, the magnetic fixing method is easy to disassemble. After the operation is completed, the card holder 25 can be separated from the reinforcing bar by simply prying it open, which improves the overall operation efficiency.
[0023] like Figure 1-4 As shown: The entire operation process does not require manual handling of the straightening steel bars, which can greatly reduce the labor intensity of the operators and avoid the physical exertion caused by continuous force when manually bending and binding steel bars. Especially for vertical steel bars, there is no need to rely on manpower to maintain the position of the steel bars. Through the stable fitting of the "U"-shaped structure of the alignment frame 1, the locking cooperation between the connecting cylinder 2 and the adjusting column 21, and the "C"-shaped limit of the straightening seat 11, the automatic positioning of the steel bars can be achieved, reducing physical exertion. Secondly, it can significantly improve the straightening accuracy. When manually held, the steel bar is prone to deviation due to hand tremors or uneven force. In this solution, the straightening seat 11 moves directionally along the guide rod 15 through the guide seat 110. The "T"-shaped structure of the screw 12 and the operating rod 13 can transmit the straightening force at a uniform speed, making the pressure applied to the steel bar by the "C"-shaped straightening seat 11 more uniform. It can accurately straighten the steel bar to a parallel butt joint state and avoid welding quality problems caused by manual operation errors. Furthermore, it improves operational safety. When manually holding the rebar, the operator's hand needs to be close to the rebar, which can easily lead to cuts from the rebar's edge or burns from welding sparks. Without manual holding, the operator can complete the operation by rotating the force ball 14 at the end of the operating rod 13, maintaining a safe distance between the hand and the rebar and welding area, thus reducing safety hazards. Finally, it improves operational efficiency. Without the need for manual adjustment of the rebar position and continuous holding, the operator can quickly complete steps such as fixing the alignment frame 1 and rotating the operating rod 13. Moreover, the straightening process is stable and controllable, reducing the time wasted due to repeated manual adjustments and accelerating the overall process of welding a single rebar.
