[0092] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0093] like Figures 1-19 As shown, this utility model provides a welding device, including a support frame 1, a traction device 2, a welding frame 3, a shifting device 4, and a first welding device 5. The traction device 2 is installed on the support frame 1 and can traction the longitudinal reinforcement bars to move along a first direction. The shifting device 4 is adjustablely positioned on the welding frame 3 along a second direction. The first welding device 5 is installed at the output end of the shifting device 4 and can drive the first welding device 5 to move along a third direction. The first, second, and third directions are perpendicular to each other. The first welding device 5 can weld the stirrups 100 one by one onto the longitudinal reinforcement bars traction by the traction device 2.

[0094] In this invention, a traction device 2 is provided on the support frame 1. The traction device 2 can pull the longitudinal reinforcement to move along the first direction, so that the longitudinal reinforcement can reliably and accurately step forward. On the welding frame 3, the shifting device 4 can adjust its position along the second direction and drive the first welding device 5 to move along the third direction. This can meet the welding requirements of stirrups 100 of various sizes and shapes, occupy little space, and have low processing costs. Ultimately, it ensures that the stirrups 100 are accurately welded at certain intervals, with high processing efficiency and stable processing quality.

[0095] In this embodiment, the support frame 1 is long and extends along the first horizontal direction. It is assembled from multiple sections, which facilitates disassembly and transportation. The welding frame 3 is located at one end of the support frame 1 along its length. The second direction is horizontal and the third direction is vertical.

[0096] Specifically, the traction device 2 includes a traction frame 21, a first clamping mechanism 22, and a traction drive mechanism 23. The traction frame 21 is slidably mounted on the support frame 1 along a first direction. The first clamping mechanism 22 is adjustablely mounted on the traction frame 21 along a second direction and is capable of clamping the longitudinal reinforcement. The traction drive mechanism 23 is mounted on the support frame 1 and is capable of driving the traction frame 21 to move. This configuration enables the traction device 2 to stably and reliably clamp and pull the longitudinal reinforcement.

[0097] More specifically, the bottom of the traction frame 21 is a pulley seat, and multiple sets of bearings are installed on both sides of the pulley seat via support shafts. The multiple sets of bearings on each side are clamped together by the upper and lower parts of the bearing frame 1, thereby realizing the smooth sliding of the traction frame 21 along the first direction. The support shaft can be an eccentric shaft, and the eccentric position can be adjusted according to the actual situation so that the bearings can be clamped on the bearing frame 1 with appropriate tightness.

[0098] In this embodiment, a chain frame is also provided on the traction frame 21. The traction drive mechanism 23 is a sprocket drive mechanism, including a motor, a drive sprocket, a driven sprocket, and a chain. The motor and the drive sprocket are installed at one end of the support frame 1. The motor can drive the drive sprocket to rotate around its own axis. The driven sprocket is rotatably installed at the other end of the support frame 1. The chain is wound around the drive sprocket and the driven sprocket and connected to the chain frame. In addition, two sets of needle roller bearings 211 are provided in the middle of the traction frame 21. The two sets of needle roller bearings 211 are inserted in the gap in the middle of the support frame 1 for positioning and to prevent the traction frame 21 from deviating from the track when it moves.

[0099] In other embodiments, the traction drive mechanism 23 may also be a belt conveyor mechanism, including a motor, a drive pulley, a driven pulley and a conveyor belt. The motor and the drive pulley are mounted on one end of the support frame 1. The motor can drive the drive pulley to rotate around its own axis. The driven pulley is rotatably mounted on the other end of the support frame 1. The conveyor belt is wound around the drive pulley and the driven pulley and connected to the chain frame.

[0100] Specifically, the first clamping mechanism 22 includes a transport support column 221, a clamping frame 222, and a clamping actuator 223. The transport support column 221 is adjustablely positioned on the traction frame 21 along a second direction, the clamping frame 222 is adjustablely positioned on the transport support column 221 along a third direction, and the clamping actuator 223 is positioned on the clamping frame 222, capable of pressing the longitudinal reinforcement against the clamping frame 222. This configuration allows the first clamping mechanism 22 to flexibly adjust its clamping position, adapting to the welding of stirrups 100 of various shapes and sizes.

[0101] More specifically, the first clamping mechanism 22 also includes a locking driver 224, which is disposed on the clamping frame 222 and can abut against the transfer support column 221 to lock the clamping frame 222.

[0102] More specifically, the clamping frame 222 includes a clamping base and a swing arm rotatably connected to the clamping base. The clamping base is slidably sleeved on the transfer bearing column 221. The locking driver 224 is installed on the clamping base. One end of the swing arm is rotatably connected to the clamping base, with the rotation axis parallel to a third direction. The other end is provided with a clamping groove. The clamping driver 223 can drive the pressure block 225 to extend into the clamping groove to clamp and lock the longitudinal rib.

[0103] In this embodiment, the clamping driver 223 and the locking driver 224 are cylinders. The pressing end of the pressure block 225 at the output end of the clamping driver 223 is provided with serrations, so as to clamp the longitudinal rib more firmly. The traction frame 21 is provided with an optical axis, and the transfer bearing column 221 is slidably sleeved on the optical axis. The end of the transfer bearing column 221 is provided with a sliding groove that runs through the second direction. The sliding groove is slidably sleeved on the protrusion on the traction frame 21, so as to realize the stable sliding of the first clamping mechanism 22 relative to the traction frame 21. Furthermore, an adjusting bolt is screwed onto the transfer bearing column 221. When the adjusting bolt abuts against the traction frame 21, it can lock the transfer bearing column 221.

[0104] In other embodiments, the clamping driver 223 and the locking driver 224 may also be electric cylinders or hydraulic cylinders, etc.

[0105] Specifically, the traction device 2 also includes a second clamping mechanism 24, which is fixedly mounted on the traction frame 21 and can clamp the longitudinal reinforcement bars. The position of the second clamping mechanism 24 remains unchanged, and it can pull the longitudinal reinforcement bars that serve as a reference, so that the reference of the formed steel beam and column remains stable and reliable regardless of the shape and size of the stirrups 100. The first clamping mechanism 22 adjusts its position based on the second clamping mechanism 24.

[0106] More specifically, the second clamping mechanism 24 includes a support rod and a clamping driver 223. One end of the support rod is fixedly connected to the traction frame 21, and the other end is provided with a clamping groove. The clamping driver 223 can drive the pressure block 225 to extend into the clamping groove to clamp and lock the longitudinal rib.

[0107] In this embodiment, for the rectangular stirrup 100, the traction device 2 includes two first clamping mechanisms 22 and one second clamping mechanism 24, which can traction a total of three longitudinal bars. The longitudinal bars clamped by the two first clamping mechanisms 22 are used to weld to the two opposite side walls of the stirrup 100, and the longitudinal bars clamped by the one second clamping mechanism 24 are used to weld to the bottom wall of the stirrup 100.

[0108] Specifically, the shifting device 4 includes a welding support column 41, a moving frame 42, and a shifting driver 43. The welding support column 41 is adjustablely positioned on the welding frame 3 along a second direction, the moving frame 42 is adjustablely positioned on the welding support column 41 along a third direction, the first welding device 5 is mounted on the moving frame 42, and the shifting driver 43 is mounted on the welding support column 41, enabling it to drive the moving frame 42 to move. This configuration makes the position adjustment of the first welding device 5 simpler and more reliable.

[0109] More specifically, the welding frame 3 is provided with an optical axis, and the welding support column 41 is slidably sleeved on the optical axis. The end of the welding support column 41 is provided with a sliding groove that runs through the second direction. The sliding groove is slidably sleeved on the protrusion on the welding frame 3, thereby realizing the stable sliding of the displacement device 4 relative to the welding frame 3. Furthermore, the welding support column 41 is also provided with a locking mechanism. When the locking mechanism abuts against the welding frame 3, it can lock the welding support column 41. The locking mechanism can be a cylinder or a bolt.

[0110] More specifically, the shift actuator 43 includes a drive motor and a drive screw. The drive motor is mounted on the welded support column 41, and its output end is connected to the drive screw. The drive screw extends along a third direction, is rotatably mounted on the welded support column 41, and is screwed to the movable frame 42. This configuration makes the position adjustment of the movable frame 42 in the third direction more precise and reliable.

[0111] In this embodiment, the movable frame 42 is provided with multiple sets of bearings, which clamp the welded bearing column 41, thereby making the sliding movement more stable and reliable.

[0112] In other embodiments, the shift driver 43 may also be an electric cylinder or a rack and pinion drive mechanism, etc.

[0113] Specifically, the first welding device 5 includes a fixed base 51, an adjusting base 52, a fixed electrode 53, a driving mechanism 54, and a movable electrode 55. The fixed base 51 is fixedly mounted on the output end of the shifting device 4 and has an arc-shaped sliding track 511. The adjusting base 52 can slide along the sliding track 511 for orientation adjustment. The adjusting base 52 has a wire inlet hole 521. The fixed electrode 53 is mounted on the adjusting base 52, the driving mechanism 54 is mounted on the adjusting base 52, and the movable electrode 55 is mounted on the output end of the driving mechanism 54. A longitudinal rib passing through the wire inlet hole 521 is located between the fixed electrode 53 and the movable electrode 55. The driving mechanism 54 can drive the movable electrode 55 to move towards the fixed electrode 53. Compared to a circular track, the fixed base 51 with an arc-shaped sliding track 511 occupies less space. On this basis, the adjusting base 52 supports the fixed electrode 53, the driving mechanism 54, and the movable electrode 55, and can drive the fixed electrode 53, the driving mechanism 54, and the movable electrode 55 to slide along the sliding track 511 for orientation adjustment, making the orientation adjustment of welding more flexible and convenient. It eliminates the need for the configuration of the driving mechanism 54 such as the robot, reduces the processing cost, and can meet the welding needs of stirrups 100 of various sizes and shapes.

[0114] Specifically, the sliding track 511 includes two coaxially arranged arc-shaped rails, and the adjusting seat 52 can slide along the two arc-shaped rails. The two arc-shaped rails cooperate to prevent the adjusting seat 52 from translating when sliding, so that the adjusting seat 52 can deflect stably and reliably for orientation adjustment.

[0115] More specifically, the first welding device 5 also includes a fastener. The arc-shaped rail is an elongated hole 5111. The fastener passes through the elongated hole 5111 and is screwed to the adjusting seat 52. The fastener has a tightened state and a released state. When the fastener is in the tightened state, the fixing seat 51 is clamped between the adjusting seat 52 and the head of the fastener. When the fastener is in the released state, the adjusting seat 52 can slide along the arc-shaped rail. The above configuration allows the adjusting seat 52 to be reliably locked in the set position.

[0116] In this embodiment, both the fixed seat 51 and the adjusting seat 52 are plate-shaped structures, and the fasteners are bolts. At least one bolt is inserted into each elongated hole 5111. In the tightened state, the head of the bolt abuts against the fixed seat 51 to lock the adjusting seat 52. In the released state, the distance between the adjusting seat 52 and the head of the fastener is greater than the thickness of the fixed seat 51, so that the adjusting seat 52 can slide in the elongated hole 5111 through the fastener.

[0117] In other embodiments, the arc-shaped rail can also be a grooved rail. The adjusting seat 52 is provided with a slider, which is slidably disposed in the grooved rail. In this case, the fastener is a bolt or screw, which is screwed to the adjusting seat 52 and can abut against the fixing seat 51.

[0118] Specifically, the fixed base 51 is provided with a clearance hole 512, and the wire inlet hole 521 is connected to the clearance hole 512. The above arrangement allows the reinforcing bar to be fed in with the clearance hole 512 as a reference, and then extends into the space between the fixed electrode 53 and the movable electrode 55 through the wire inlet hole 521, making it more stable and reliable.

[0119] More specifically, the sliding track 511 is centered on the axis of the clearance hole 512. This arrangement ensures that when the adjusting seat 52 slides relative to the fixed seat 51, the clearance hole 512 is always reliably connected to the inlet hole 521.

[0120] In this embodiment, the inlet hole 521 is elongated, and its length direction is parallel to the moving direction of the driving mechanism 54 driving the movable electrode 55. This arrangement allows the elongated hole 5111 to initially limit the movement of the reinforcing bar inserted therethrough.

[0121] Specifically, the drive mechanism 54 includes a driver 541 and an insulating plate 542. The driver 541 is mounted on the adjusting base 52, and the movable electrode 55 is connected to the output end of the driver 541 via the insulating plate 542. By setting the insulating plate 542, the fixed electrode 53 and the movable electrode 55 can perform welding operations safely and reliably.

[0122] More specifically, the drive mechanism 54 also includes a support frame 543, a guide post 544, and an electrode holder 545. The support frame 543 is mounted on the adjusting seat 52, the driver 541 is mounted on the support frame 543, the guide post 544 is slidably disposed on the support frame 543, one end is connected to the output end of the driver 541, and the other end is connected to the insulating plate 542. The electrode holder 545 is mounted on the side of the insulating plate 542 opposite to the guide post 544, and the movable electrode 55 is mounted on the side of the electrode holder 545 opposite to the insulating plate 542. The support frame 543, guide post 544, and electrode holder 545 cooperate to enable the driver 541 to drive the movable electrode 55 more stably and reliably.

[0123] In this embodiment, the actuator 541 is a cylinder. In other embodiments, the actuator 541 may also be a linear drive device such as an electric cylinder.

[0124] Specifically, the electrode holder 545 is provided with a first flow channel 5451 and a first inlet / outlet 5452 and a second inlet / outlet 5453 connected to the first flow channel 5451. The movable electrode 55 is connected to the opening of the first flow channel 5451. Since welding generates a large amount of heat, cooling is required. In the above configuration, the first inlet / outlet 5452 and the second inlet / outlet 5453 are respectively a water inlet and a water outlet. The water entering from the water inlet flows through the movable electrode 55 in the first flow channel 5451 and then flows out from the water outlet, thus achieving water cooling of the movable electrode 55.

[0125] More specifically, a water inlet copper core 546 is provided in the first flow channel 5451, a first sink is provided on the movable electrode 55, a first threaded hole 5454 is provided at the bottom of the first flow channel 5451, and a first inlet / outlet 5452 is connected to the first flow channel 5451 through the first threaded hole 5454. One end of the water inlet copper core 546 is screwed into the first threaded hole 5454 and connected to the first inlet / outlet 5452, and the other end extends into the first sink, so that cooling water can extend into the movable electrode 55 for cooling.

[0126] In this embodiment, the drive mechanism 54 further includes a guide rod 547, a copper limiting sleeve 548, and a fastening member 549. One end of the guide rod 544 is provided with a first connecting block. The insulating plate 542 is a plate made of insulating material and is laid and installed on the first connecting block. The guide rod 547 passes through the sliding groove of the support frame 543 and is provided with a second connecting block at one end. The second connecting block is connected to the first connecting block by bolts, thereby interfering with the rotation of the guide rod 544. A copper limiting sleeve 548 is provided on each side of the guide rod 547. Each copper limiting sleeve 548 is equipped with a fastening member 549. The fastening member 549 is a bolt and is screwed to the support frame 543. One end of the fastening member 549 extending into the sliding groove is connected to the copper limiting sleeve 548. By limiting the two copper limiting sleeves 548, the guide rod 547 can be stably translated and extended.

[0127] In other embodiments, a guide groove may be provided on the guide post 544, extending along the axial direction of the guide post 544, and a steel key may be installed on the support frame 543, extending into the guide groove, thereby interfering with the rotation of the guide post 544.

[0128] Specifically, the first welding device 5 also includes a transformer 56, with two output electrodes: a first output electrode 561 and a second output electrode 562. The first output electrode 561 is electrically connected to the fixed electrode 53, and the second output electrode 562 is electrically connected to the movable electrode 55. This arrangement ensures that the fixed electrode 53 and the movable electrode 55 can be reliably connected to the power supply.

[0129] More specifically, the first output electrode 561 is electrically connected to the fixed electrode 53 via the adjusting seat 52. This arrangement makes the electrical connection between the first output electrode 561 and the fixed electrode 53 simpler and more reliable.

[0130] In this embodiment, the adjusting seat 52 is an aluminum plate. Aluminum plates have good electrical conductivity and play a conductive role in welding. The first output electrode 561 is connected to the aluminum plate via a side-connecting copper seat 563. The fixed electrode 53 is connected to the aluminum plate via a brass base 564. The second output electrode 562 is connected to the electrode seat 545 via a flexible wire 565, and then electrically connected to the movable electrode 55. When the fixed electrode 53 and the movable electrode 55 clamp the longitudinal rib and the stirrup 100, a closed circuit is formed, allowing welding to be performed. During the welding process, the aluminum plate also generates heat. The aluminum plate should have advantages such as high strength, corrosion resistance, light weight, and good electrical conductivity. Therefore, this embodiment uses 7075 alloy aluminum, but is not limited to 7075 alloy aluminum.

[0131] Specifically, the brass base 564 is provided with a second flow groove and a third and a fourth inlet / outlet connected to the second flow groove. The fixed electrode 53 is connected to the opening of the second flow groove. Due to the large amount of heat generated during welding, cooling is required. The third and the fourth inlet / outlet are water inlets and outlets, respectively. Water entering from the inlet flows through the fixed electrode 53 in the second flow groove and then flows out from the outlet, thus achieving water cooling of the fixed electrode 53. A water inlet copper core 546 can also be provided in the second flow groove. A second sink is provided on the fixed electrode 53. A second threaded hole is provided at the bottom of the second flow groove. One end of the water inlet copper core 546 is screwed into the second threaded hole and connected to the third inlet / outlet, while the other end extends into the first sink, so that cooling water can extend into the interior of the fixed electrode 53 for cooling.

[0132] More specifically, a small, flexible, and lightweight transformer 56 is selected. Threaded holes are provided on the side of the transformer 56 so that it can be installed on an aluminum plate. Furthermore, a flow channel is provided on the transformer 56 to connect the first output electrode 561 and the second output electrode 562. The flow channel is connected to the outside through the fifth inlet and outlet and the sixth inlet and outlet. Heat is generated during welding operations, and the transformer 56 can be cooled by water cooling.

[0133] Specifically, the first welding device 5 further includes a straightening mechanism 57, which comprises a straightening seat 571, a straightening sleeve 572, and multiple straightening wheels. The straightening seat 571 is installed at the output end of the shifting device 4, the straightening sleeve 572 is disposed on the straightening seat 571, and the multiple straightening wheels are rotatably disposed on the straightening seat 571, forming a straightening channel between them. The longitudinal reinforcement passes sequentially through the straightening sleeve 572, the straightening channel, and the inlet hole 521 before being clamped in the traction device 2. This arrangement ensures that the longitudinal reinforcement is straightened before being welded to the stirrups 100, further guaranteeing the accuracy and reliability of the spacing between the stirrups 100.

[0134] More specifically, there are two types of straightening wheels: a first straightening wheel 573 and a second straightening wheel 574. Multiple first straightening wheels 573 and multiple second straightening wheels 574 are provided. A second straightening wheel 574 is provided on the symmetrical plane of two adjacent first straightening wheels 573. A straightening channel is formed between the first straightening wheels 573 and the second straightening wheels 574. The first straightening wheel 573 is rotatably mounted on the straightening seat 571 via a first wheel shaft, and the second straightening wheel 574 is rotatably mounted on the straightening seat 571 via a second wheel shaft. The first wheel shaft is a straight wheel shaft, and the second wheel shaft is an eccentric shaft. The eccentric position of the second wheel shaft can be adjusted according to the diameter of the precast longitudinal reinforcement 200, thereby adjusting the distance between the first straightening wheel 573 and the second straightening wheel 574 so that the precast longitudinal reinforcement 200 can be straightened after deformation.

[0135] The first welding device 5 of this utility model is used to weld rectangular stirrups 100. In addition, it can also weld longitudinal bars and stirrups 100 of other shapes together, such as circular and various other shapes of stirrups 100.

[0136] The welding method of the first welding device 5 includes the following steps:

[0137] Step 1: Adjust the position of the adjusting seat 52 by sliding it along the sliding track 511 so that the line connecting the fixed electrode 53 and the movable electrode 55 is perpendicular to the tangent of the stirrup 100 at the point to be welded.

[0138] Step 2: Place the stirrup 100 to be welded between the fixed electrode 53 and the movable electrode 55;

[0139] Step 3: Insert the longitudinal rib through the inlet hole 521 between the fixed electrode 53 and the movable electrode 55, so that the longitudinal rib is located on the side of the stirrup 100 away from the fixed electrode 53 at the welding point.

[0140] Step 4: The driving mechanism 54 drives the movable electrode 55 to move toward the fixed electrode 53, so that the weldable parts of the longitudinal ribs and stirrups 100 are sandwiched between the fixed electrode 53 and the movable electrode 55.

[0141] Step 5: The fixed electrode 53 and the movable electrode 55 are energized to weld the longitudinal ribs and stirrups 100 at the welding points.

[0142] Specifically, the welding equipment also includes a second welding device 6, which is fixedly mounted on the welding frame 3 and can weld the stirrups 100 one by one to the longitudinal bars pulled by the traction device 2. The position of the second welding device 6 remains unchanged, and welding operations can be performed based on it, so that the reference of the formed steel beam and column is stable and reliable regardless of the shape and size of the stirrups 100. The first welding device 5 adjusts its position based on the second welding device 6.

[0143] More specifically, the second welding device 6 omits the fixed base 51 compared to the first welding device 5, but the other structures are the same as the first welding device 5. The adjustment base 52 and the straightening mechanism 57 of the second welding device 6 are mounted on the welding frame 3.

[0144] In this embodiment, for the rectangular stirrup 100, the welding equipment includes two first welding devices 5 and one second welding device 6, which can weld a total of three longitudinal bars. The two first welding devices 5 are each equipped with a shifting device 4, which is used to weld the two longitudinal bars to the two opposite side walls of the stirrup 100. The second welding device 6 is used to weld the longitudinal bars to the bottom wall of the stirrup 100.

[0145] To further ensure welding quality, both first welding devices 5 and one second welding device 6 are equipped with limit blocks 58. The limit blocks 58 are installed on the adjusting seat 52 and located between the fixed electrode 53 and the movable electrode 55 to limit the position of the stirrup 100. Along the first direction, the three sets of limit blocks 58 are adjusted to the same position so that the stirrup 100 and the three weld points of the three longitudinal bars can be relatively flush.

[0146] Specifically, the welding equipment also includes a wire feeding device 7, which includes a wire feeding base and a wire feeding shaft rotatably mounted on the wire feeding base, with the longitudinal ribs wound onto the wire feeding shaft.

[0147] In this embodiment, three wire-laying devices 7 are provided, which can simultaneously lay out three longitudinal ribs.

[0148] This utility model also provides a method for processing reinforced beams and columns, using the aforementioned welding equipment, including:

[0149] Step 1: Adjust the position of the shifting device 4 on the welding frame 3 according to the shape and size of the stirrup 100, and control the shifting device 4 to drive the first welding device 5 to the set position.

[0150] In this step, the two shifting devices 4 drive the two first welding devices 5 to move in the second direction, and respectively drive the two first welding devices 5 to move in the third direction. Then, the adjusting seat 52 slides along the sliding track 511 to adjust the orientation, so that the line connecting the fixed electrode 53 and the movable electrode 55 is perpendicular to the tangent of the stirrup 100 to be welded.

[0151] The two first welding devices 5 and the two first clamping mechanisms 22 correspond one-to-one in the first direction and cooperate with each other. According to the position of the two first welding devices 5, the position of the two first clamping mechanisms 22 is adjusted, the position of the transport bearing column 221 is adjusted along the second direction, and the position of the clamping frame 222 on the transport bearing column 221 is adjusted along the third direction.

[0152] The second welding device 6 and the second clamping mechanism 24 cooperate in the first direction.

[0153] According to the diameter of the precast longitudinal rib 200, the eccentric position of the second wheel shaft in the straightening mechanism 57 is adjusted, thereby adjusting the distance between the first straightening wheel 573 and the second straightening wheel 574 so that the precast longitudinal rib 200 can be straightened after deformation.

[0154] After the three prefabricated longitudinal ribs 200 are led out from the three wire feeding devices 7, they pass through the straightening sleeve 572, the straightening channel and the wire inlet hole 521 in sequence, and are pressed against the clamping groove by the clamping block 225 driven by the clamping driver 223.

[0155] Step 2: The traction device 2 pulls the precast longitudinal reinforcement 200 in steps according to the set length. After each step, the first welding device 5 welds a stirrup 100 to the precast longitudinal reinforcement 200.

[0156] In this step, the traction drive mechanism 23 drives the traction frame 21 to advance step by step according to the set length, gradually pulling the precast longitudinal reinforcement 200 to the bearing frame 1. The stirrup 100 is placed on the two first welding devices 5 and the second welding device 6 by manual or robotic operation. The two first welding devices 5 and the second welding device 6 cooperate to weld the three precast longitudinal reinforcements 200 to the stirrup 100.

[0157] Step 3: Weld the set number of stirrups 100 onto the precast longitudinal bars 200 to form precast steel beams and columns.

[0158] In this step, the precast steel beams and columns are fabricated.

[0159] Step 4: Tie 300mm of finished longitudinal reinforcement bars onto the precast steel beams and columns to obtain finished steel beams and columns.

[0160] In this step, the precast steel beams and columns are transported to the construction site. At the construction site, the finished longitudinal bars 300 are tied to the precast steel beams and columns by hand. Since the stirrups 100 have been welded and fixed at the required spacing, it is not necessary to tie each stirrup 100 to the finished longitudinal bar 300.

[0161] The processing method of the steel beams and columns of this utility model can pre-form the precast steel beams and columns in the prefabrication plant, and then transport them to the construction site for binding and connection with the finished longitudinal bars 300. Since the stirrups 100 have been welded and fixed at the required spacing, the finished longitudinal bars 300 only need to be bound at five to six stirrup 100 positions, which greatly improves construction efficiency and reduces construction costs.

[0162] In this embodiment, the diameter of the precast longitudinal reinforcement 200 is smaller than the diameter of the finished longitudinal reinforcement 300. For the rectangular stirrup 100, three precast longitudinal reinforcements 200 are welded on the precast steel beam and column, which can ensure the support and fixation of the stirrup 100 with minimal material usage. Four finished longitudinal reinforcements 300 are provided and tied at the four corners of the stirrup 100. The precast longitudinal reinforcements 200 and the finished longitudinal reinforcements 300 work together to improve the structural strength of the finished steel beam and column.
