[0093] like Figure 1-Figure 19 As shown, the present invention provides a welding device, including a bearing 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 bearing frame 1, and can pull the longitudinal reinforcement to move along the first direction.

[0094] In the present invention, a traction device 2 is arranged on the supporting frame 1, and the traction device 2 can pull the longitudinal reinforcement to move along the first direction, so that the longitudinal reinforcement can step reliably and accurately.

[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 through support shafts. The multiple sets of bearings on each side are clamped on the supporting frame 1 up and down, thereby realizing the smooth sliding of the traction frame 21 along the first direction.

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

[0100] Specifically, the first clamping mechanism 22 includes a transport bearing column 221, a clamping frame 222 and a clamping driver 223. The transport bearing column 221 is adjustably disposed on the traction frame 21 along the second direction, the clamping frame 222 is adjustably disposed on the transport bearing column 221 along the third direction, and the clamping driver 223 is disposed on the clamping frame 222, and can press the longitudinal reinforcement against the clamping frame 222.

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

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

[0103] In this embodiment, the clamping driver 223 and the locking driver 224 are cylinders, and the pressing end of the pressure block 225 at the output end of the clamping driver 223 is provided with serrations, so that the longitudinal reinforcement can be clamped more firmly. An optical axis is provided on the traction frame 21, 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 passes through along the second direction, and the sliding groove is slidably sleeved on the convex ridge on the traction frame 21, so as to realize the stable sliding of the first clamping mechanism 22 relative to the traction frame 21, and an adjusting bolt is also screwed on the transfer bearing column 221. When the adjusting bolt abuts against the traction frame 21, the transfer bearing column 221 can be locked.

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

[0105] Specifically, the traction device 2 further includes a second clamping mechanism 24, which is fixedly disposed on the traction frame 21 and can clamp the longitudinal reinforcement. The second clamping mechanism 24 remains in a constant position and can pull the longitudinal reinforcement as a reference, so that no matter how the shape and size of the stirrup 100 change, the reference of the formed steel bar beam column is stable and reliable, and the first clamping mechanism 22 is adjusted in position based on the second clamping mechanism 24.

[0106] More specifically, the second clamping mechanism 24 includes a load-bearing rod and a clamping driver 223. One end of the load-bearing 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 reinforcement.

[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 pull a total of three longitudinal bars. The longitudinal bars clamped by the two first clamping mechanisms 22 are used to be welded 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 be welded to the bottom wall of the stirrup 100.

[0108] Specifically, the shift device 4 includes a welding support column 41, a mobile frame 42 and a shift driver 43. The welding support column 41 is adjustable along the second direction on the welding frame 3, the mobile frame 42 is adjustable along the third direction on the welding support column 41, the first welding device 5 is arranged on the mobile frame 42, and the shift driver 43 is arranged on the welding support column 41, which can drive the mobile frame 42 to move. The above arrangement makes the position adjustment of the first welding device 5 more convenient and reliable.

[0109] More specifically, an optical axis is provided on the welding frame 3, and a welding bearing column 41 is slidably mounted on the optical axis. A slide groove penetrating along the second direction is provided at the end of the welding bearing column 41, and the slide groove is slidably mounted on the convex ridge on the welding frame 3, thereby realizing stable sliding of the shifting device 4 relative to the welding frame 3, and a locking mechanism is also provided on the welding bearing column 41. When the locking mechanism abuts against the welding frame 3, the welding bearing column 41 can be locked. The locking mechanism can be a cylinder or a bolt.

[0110] More specifically, the shift driver 43 includes a drive motor and a drive screw, the drive motor is mounted on the welding support column 41, the output end is connected to the drive screw, the drive screw extends along the third direction, is rotatably disposed on the welding support column 41, and is screwed to the moving frame 42. The above arrangement makes the position adjustment of the moving frame 42 in the third direction more accurate and reliable.

[0111] In this embodiment, a plurality of bearings are disposed on the movable frame 42 , and the movable frame 42 is clamped on the welded bearing column 41 by the plurality of bearings, so that the movable frame 42 is more stable and reliable during sliding.

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

[0113] Specifically, the first welding device 5 includes a fixed seat 51, an adjustment seat 52, a fixed electrode 53, a driving mechanism 54 and a movable electrode 55. The fixed seat 51 is fixedly arranged at the output end of the shift device 4, and an arc-shaped sliding track 511 is arranged thereon. The adjustment seat 52 can slide along the sliding track 511 for position adjustment. The adjustment seat 52 is provided with a wire entry hole 521. The fixed electrode 53 is installed on the adjustment seat 52. The driving mechanism 54 is installed on the adjustment seat 52. The movable electrode 55 is installed at the output end of the driving mechanism 54. The longitudinal ribs passing through the wire entry hole 521 are located between the fixed electrode 53 and the movable electrode 55. The driving mechanism 54 can drive the movable electrode 55 to move toward the fixed electrode 53. In the above arrangement, compared with a circular track, the fixed seat 51 with an arc-shaped sliding track 511 occupies less space. On this basis, the adjustment seat 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 position adjustment, making the position adjustment of welding more flexible and convenient, omitting the configuration of the driving mechanism 54 such as a manipulator, reducing the processing cost, and being able to meet the welding requirements of stirrups 100 of various sizes and shapes.

[0114] Specifically, the sliding track 511 includes two coaxially arranged arc rails, and the adjustment seat 52 can slide along the two arc rails. The two arc rails cooperate with each other to avoid translation of the adjustment seat 52 when sliding, so that the adjustment seat 52 can stably and reliably deflect to adjust the position.

[0115] More specifically, the first welding device 5 further includes a fastener, the arc rail is a long hole 5111, the fastener is inserted into the long hole 5111, and is screwed to the adjustment seat 52, the fastener has a fastened state and a released state, when the fastener is in the fastened state, the fixed seat 51 is clamped between the adjustment seat 52 and the head of the fastener, when the fastener is in the released state, the adjustment seat 52 can slide along the arc rail. The above arrangement enables the adjustment seat 52 to be reliably locked in the set position.

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

[0117] In other embodiments, the arc rail may also be a groove rail, and a slider is provided on the adjustment seat 52 , and the slider is slidably set in the groove rail. In this case, the fastener is a bolt or a screw, which is screwed to the adjustment seat 52 and can abut against the fixed seat 51 .

[0118] Specifically, the fixing seat 51 is provided with an avoidance hole 512, and the wire entry hole 521 is connected to the avoidance hole 512. The above arrangement enables the steel bar to be fed based on the avoidance hole 512, and then extend through the wire entry hole 521 into between the fixed electrode 53 and the movable electrode 55, which is more stable and reliable.

[0119] More specifically, the sliding track 511 takes the axis of the avoidance hole 512 as its axis. The above arrangement enables the avoidance hole 512 to always be reliably connected to the wire inlet hole 521 when the adjustment seat 52 is slidingly adjusted relative to the fixed seat 51 .

[0120] In this embodiment, the wire entry hole 521 is in an elongated shape, and the length direction of the wire entry hole 521 is parallel to the moving direction of the movable electrode 55 driven by the driving mechanism 54. The above arrangement enables the elongated hole 5111 to initially limit the steel bars passing therethrough.

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

[0122] More specifically, the driving mechanism 54 further includes a support frame 543, a guide column 544 and an electrode holder 545. The support frame 543 is mounted on the adjustment holder 52, the driver 541 is mounted on the support frame 543, the guide column 544 is slidably disposed on the support frame 543, one end of which 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 away from the guide column 544, and the movable electrode 55 is mounted on the side of the electrode holder 545 away from the insulating plate 542. The support frame 543, the guide column 544 and the electrode holder 545 cooperate with each other, so that the driver 541 can drive the movable electrode 55 more stably and reliably.

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

[0124] Specifically, the electrode holder 545 is provided with a first flow slot 5451 and a first water inlet and outlet 5452 and a second water inlet and outlet 5453 connected to the first flow slot 5451, and the movable electrode 55 is connected to the notch of the first flow slot 5451. Since welding generates a large amount of heat, it is necessary to cool down. In the above configuration, the first water inlet and outlet 5452 and the second water inlet and outlet 5453 are one water inlet and the other water outlet. The water entering from the water inlet flows through the movable electrode 55 in the first flow slot 5451 and then flows out from the water outlet, thereby achieving water cooling of the movable electrode 55.

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

[0126] In this embodiment, the driving mechanism 54 also includes a guide rod 547, a copper limit sleeve 548 and a fastener 549. A first connecting block is arranged at one end of the guide column 544. The insulating plate 542 is a plate made of insulating material, which is laid and installed on the first connecting block. The guide rod 547 is inserted into the sliding groove of the support frame 543, and a second connecting block is arranged at one end. The second connecting block is connected to the first connecting block by bolts, so as to interfere with the rotation of the guide column 544. A copper limit sleeve 548 is arranged on both sides of the guide rod 547, and each copper limit sleeve 548 is configured with a fastener 549. The fastener 549 is a bolt, which is screwed to the support frame 543. One end of the fastener 549 extending into the sliding groove is connected to the copper limit sleeve 548. The two copper limit sleeves 548 are used to limit the guide rod 547, so that the guide rod 547 can stably translate and retract.

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

[0128] Specifically, the first welding device 5 further includes a transformer 56, and the two output electrodes of the transformer 56 are respectively 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. The above arrangement enables the fixed electrode 53 and the movable electrode 55 to be installed and reliably connected to the power supply.

[0129] More specifically, the first output electrode 561 is electrically connected to the fixed electrode 53 through the adjustment base 52. The above arrangement makes the electrical connection between the first output electrode 561 and the fixed electrode 53 more convenient and reliable.

[0130] In this embodiment, the adjustment seat 52 is an aluminum plate, which has good electrical conductivity and plays a conductive role in welding. The first output electrode 561 is connected to the aluminum plate through the side copper seat 563, the fixed electrode 53 is connected to the aluminum plate through the brass base 564, and the second output electrode 562 is connected to the electrode seat 545 through the soft wire 565, and then electrically connected to the movable electrode 55. When the fixed electrode 53 and the movable electrode 55 clamp the longitudinal reinforcement and the stirrup 100, a closed loop is formed, so that welding can be performed. During the welding process, the aluminum plate will also generate heat. The aluminum plate should have the advantages of high strength, corrosion resistance, light weight, good electrical conductivity, etc., so 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 circulation groove and a third water inlet and a fourth water inlet and outlet connected to the second circulation groove. The fixed electrode 53 is connected to the groove of the second circulation groove. Since a large amount of heat is generated by welding, cooling is required. The third water inlet and the fourth water inlet and outlet are a water flow inlet and a water flow outlet respectively. The water entering from the water flow inlet flows through the fixed electrode 53 in the second circulation groove and then flows out from the water flow outlet, thereby realizing water cooling of the fixed electrode 53. A water inlet copper core 546 may also be provided in the second circulation groove. A second trough is provided on the fixed electrode 53. A second threaded hole is provided at the bottom of the second circulation groove. One end of the water inlet copper core 546 is screwed into the second threaded hole and connected to the third water inlet and outlet, and the other end extends into the first trough, so that the cooling water flow can extend into the interior of the fixed electrode 53 for cooling.

[0132] More specifically, a transformer 56 with smaller dimensions, flexibility and lightness is selected, and threaded holes are provided on the side of the transformer 56 so that it can be installed on an aluminum plate. In addition, a flow channel connecting the first output electrode 561 and the second output electrode 562 is provided on the transformer 56, and the flow channel is connected to the outside through the fifth inlet and outlet and the sixth inlet and outlet. Heat is generated during the welding operation, and the transformer 56 can be cooled by water cooling.

[0133] Specifically, the first welding device 5 also includes a straightening mechanism 57, which includes a straightening seat 571, a straightening sleeve 572 and a plurality of straightening wheels. The straightening seat 571 is installed at the output end of the shifting device 4, the straightening sleeve 572 is arranged on the straightening seat 571, and the plurality of straightening wheels are respectively rotatably arranged on the straightening seat 571, and a straightening channel is formed between the plurality of straightening wheels. The longitudinal reinforcement passes through the straightening sleeve 572, the straightening channel and the wire entry hole 521 in sequence and is clamped in the traction device 2. The above arrangement enables the longitudinal reinforcement to be welded with the stirrup 100 after straightening, further ensuring the accuracy and reliability of the spacing between the stirrups 100.

[0134] More specifically, there are two types of straightening wheels, namely a first straightening wheel 573 and a second straightening wheel 574. There are multiple first straightening wheels 573 and second straightening wheels 574 respectively. A second straightening wheel 574 is arranged on the symmetry plane of two adjacent first straightening wheels 573. A straightening channel is formed between the first straightening wheel 573 and the second straightening wheel 574. The first straightening wheel 573 is rotatably mounted on the straightening seat 571 through the first wheel axle, and the second straightening wheel 574 is rotatably mounted on the straightening seat 571 through the second wheel axle. The first wheel axle is a straight wheel axle, and the second wheel axle is an eccentric axle. The eccentric position of the second wheel axle can be adjusted according to the diameter size of the prefabricated longitudinal reinforcement 200, thereby adjusting the distance between the first straightening wheel 573 and the second straightening wheel 574, so that the prefabricated longitudinal reinforcement 200 can be straightened after deformation.

[0135] The first welding device 5 of the present invention is used to weld rectangular stirrups 100 . In addition, the first welding device 5 of the present invention can also weld longitudinal bars and stirrups 100 of other shapes, such as circular stirrups 100 and stirrups 100 of various shapes.

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

[0137] Step 1: The adjusting seat 52 slides along the sliding track 511 to adjust the position so that the connection line between the fixed electrode 53 and the movable electrode 55 is perpendicular to the tangent line of the stirrup 100 at the welding position;

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

[0139] Step 3: Extend the longitudinal reinforcement through the wire entry hole 521 and into between the fixed electrode 53 and the movable electrode 55, so that the longitudinal reinforcement is located on the side of the stirrup 100 to be welded away from the fixed electrode 53;

[0140] Step 4: The driving mechanism 54 drives the movable electrode 55 to move toward the fixed electrode 53, so that the to-be-welded portion of the longitudinal reinforcement and the stirrup 100 is 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 reinforcement and the stirrup 100 at the locations to be welded.

[0142] Specifically, the welding equipment further includes a second welding device 6, which is fixedly arranged on the welding frame 3 and can weld the stirrups 100 one by one to the longitudinal bars pulled by the pulling device 2. The second welding device 6 does not change its position, and can be used as a reference for welding operations, so that no matter how the shape and size of the stirrups 100 change, the reference of the formed steel bar beam column is stable and reliable, and the first welding device 5 is adjusted in position based on the second welding device 6.

[0143] More specifically, compared with the first welding device 5 , the second welding device 6 omits the fixing seat 51 , and other structures are the same as the first welding device 5 . The adjusting seat 52 and the straightening mechanism 57 of the second welding device 6 are installed 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 reinforcements. The two first welding devices 5 are respectively configured with a shifting device 4 for welding the two longitudinal reinforcements to the two opposite side walls of the stirrup 100, and a second welding device 6 is used to weld the longitudinal reinforcement to the bottom wall of the stirrup 100.

[0145] To further ensure the welding quality, the two first welding devices 5 and the one second welding device 6 are each provided with a limit stop 58, which is installed on the adjustment seat 52 and is located between the fixed electrode 53 and the movable electrode 55, and is used to limit the position of the stirrup 100. Along the first direction, the three groups of limit stops 58 are adjusted to the same position so that the stirrup 100 and the three welding points of the three longitudinal bars can be relatively flush.

[0146] Specifically, the welding equipment further comprises a wire-releasing device 7, which comprises a wire-releasing base and a wire-releasing shaft rotatably arranged on the wire-releasing base, and the longitudinal reinforcement is wound on the wire-releasing shaft.

[0147] In this embodiment, three pay-off devices 7 are provided, which can pay out three longitudinal ribs at the same time.

[0148] The present invention also provides a method for processing a steel bar beam column, using the above-mentioned welding equipment, comprising:

[0149] Step 1: According to the shape and size of the stirrup 100, adjust the position of the shifting device 4 on the welding frame 3, and control the shifting device 4 to drive the first welding device 5 to move 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 along the third direction, and then slide the adjustment seat 52 along the sliding track 511 for position adjustment, so that the connecting line between 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 positions of the two first welding devices 5, the positions of the two first clamping mechanisms 22 are adjusted, the moving bearing column 221 is adjusted in position along the second direction, and the clamping frame 222 is adjusted in position on the moving bearing column 221 along the third direction.

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

[0153] According to the diameter of the prefabricated longitudinal reinforcement 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 prefabricated longitudinal reinforcement 200 can be straightened after deformation.

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

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

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

[0157] Step 3: Weld a set number of stirrups 100 to the prefabricated longitudinal reinforcement 200 to form a prefabricated steel beam column.

[0158] In this step, the prefabricated reinforced beams and columns are processed.

[0159] Step 4: Tie the finished longitudinal reinforcement 300 on the prefabricated reinforced beams and columns to obtain finished reinforced beams and columns.

[0160] In this step, the processed prefabricated steel beams and columns are transported to the construction site, where the finished longitudinal reinforcement 300 is manually tied to the prefabricated steel beams and columns. Since the stirrups 100 have been welded and fixed at the required spacing, there is no need to tie each stirrup 100 to the finished longitudinal reinforcement 300.

[0161] The processing method of the steel bar beams and columns of the present invention can pre-form the prefabricated steel bar beams and columns in a prefabrication factory, and then transport them to the construction site for binding and connection with the finished longitudinal reinforcement 300. Since the stirrups 100 have been welded and fixed at the required spacing, the finished longitudinal reinforcement 300 only needs to be bound at five to six stirrups 100 positions, which greatly improves the construction efficiency and reduces the construction cost.

[0162] In this embodiment, the diameter of the prefabricated longitudinal reinforcement 200 is smaller than the diameter of the finished longitudinal reinforcement 300. For the rectangular stirrups 100, three prefabricated longitudinal reinforcements 200 are welded on the prefabricated steel beams and columns, which can ensure the support and fixation of the stirrups 100 with minimal materials. Four finished longitudinal reinforcements 300 are arranged and tied at the four corners of the stirrups 100. The prefabricated longitudinal reinforcements 200 and the finished longitudinal reinforcements 300 cooperate with each other, and can also improve the structural strength of the finished steel beams and columns.
