A template for welding steel reinforcement cages

Abstract

This utility model discloses a template for welding reinforcing steel cages, relating to the field of reinforcing steel welding technology. It includes a welding station with a first transverse positioning unit, a longitudinal positioning unit, and a second transverse positioning unit. The first transverse positioning unit and the longitudinal positioning unit have identical structures. The first transverse positioning unit includes an adjusting plate with a groove. A slider is slidably connected within the groove, and a U-frame is fixed to the slider. A clamping rod is threaded onto the U-frame, and a pressure block is fixed to the lower end of the clamping rod. This utility model, by setting the first transverse positioning unit and the longitudinal positioning unit, allows the U-frame to slide along the groove, and the longitudinal positioning unit to move and be fixed via an insertion hole, with its height adjusted by the lifting and lowering of the top plate. This overcomes the limitations of traditional templates with fixed positioning spacing and support height, and only suitable for a single specification.

Description

Technical Field

[0001] This utility model relates to the field of steel bar welding technology, specifically a template for welding steel bar skeletons. Background Technology

[0002] A rebar cage welding template is an auxiliary tool used in the fabrication of rebar cages to position, support, and fix main bars, stirrups, and other reinforcing bars. It is widely used in the welding of rebar cages for precast components, bridge piers, box girders, and segmented concrete structures. It typically has positioning slots on the base plate, side plates, or positioning plate that match the diameter and design spacing of the reinforcing bars, allowing the bars to be placed in the designed positions in one go. This ensures that the geometric dimensions, spacing, and protective layer thickness of the rebar cage meet the requirements, improving welding efficiency and forming quality.

[0003] However, for welding small and medium-sized rebar cages, traditional rebar cage welding templates mostly adopt an integral welded fixed structure, with fixed positioning slots, positioning plates, and support spacing, which can only accommodate rebar cages of a single specification. Therefore, this application proposes a novel template for welding rebar cages. Utility Model Content

The first transverse positioning unit and the longitudinal positioning unit have the same structure. The top of the welding station is detachably installed on a second transverse positioning unit located on the opposite side of the longitudinal positioning unit. The second transverse positioning unit is used for welding and positioning transverse steel reinforcement. A support seat for supporting longitudinal steel reinforcement is provided on the side of the welding station opposite to the first transverse positioning unit. The first transverse positioning unit includes an adjusting plate, on which a groove is opened. A slider is slidably connected in the groove. A U-frame is fixed on the slider. A clamping rod is threadedly connected to the U-frame. A pressure block is fixed at the lower end of the clamping rod.

[0006] Preferably, a limiting groove is provided on the adjusting plate; a screw rod is slidably passed through the top end of the clamping rod, and the length of the screw rod is greater than the distance between the clamping rod and the limiting groove.

[0007] Preferably, the adjusting plate on the first transverse positioning unit is fixed on the welding platform; the adjusting plate of the longitudinal positioning unit is fixed with a pin; and the welding platform is provided with a hole for inserting the pin.

[0008] Preferably, the length of the insertion post is greater than the depth of the insertion hole, the lower end of the insertion post extends out of the bottom of the insertion hole, and a support column is fixed at each of the four corners of the bottom of the welding station, with a base plate fixed at the lower end of the support column.

[0009] Preferably, an electric telescopic rod is fixed on the base plate, a top plate is fixed to the output end of the electric telescopic rod, and guide posts are slidably inserted at the four corners of the top plate, with the lower ends of the guide posts fixed to the base plate.

[0010] Preferably, the second lateral positioning unit includes an adjustment plate, which has a sliding groove, a moving channel above the sliding groove, and a limiting groove above the moving channel. A plug that mates with the insertion hole is fixed at the bottom of the adjustment plate.

[0011] Preferably, the second lateral positioning unit further includes a lateral positioning component; wherein, the lateral positioning component includes a slider slidably disposed in a groove, a support frame fixed on the slider, a guide opening on one side of the support frame, and guide members fixed on opposite sides of the guide opening; a lifting rod is threadedly connected to the top of the support frame, a pressure block is fixed to the bottom of the lifting rod, a screwing part is fixed to the top of the lifting rod, and a screw rod that slidably passes through the screwing part and cooperates with the limiting groove.

[0012] Preferably, a reinforcing bar carrier plate is slidably provided in the guide opening, and guide channels that slide with the guide member are provided on opposite sides of the reinforcing bar carrier plate. Horizontal channels are symmetrically provided on the top of the reinforcing bar carrier plate, and vertical openings are provided on opposite sides of the guide opening. Lifting plates are provided on opposite sides of the support frame. A support shaft that passes through the vertical opening is fixed on one side of the lifting plate. A limiting guide wheel is rotatably provided at the end of the support shaft, and a reinforcing bar limiting disc that cooperates with the horizontal channel is fixed at the end of the limiting guide wheel.

[0013] Preferably, a guide rod that slides through the support frame is fixed to the top of the lifting plate, and a reset spring connected to the support frame is provided on the top of the lifting plate; a guide wheel limiting seat is symmetrically fixed on the top of the steel bar carrier plate away from the welding station, the top of the guide wheel limiting seat is provided with a limiting groove, and curved guide surfaces are provided on opposite sides of the guide wheel limiting seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model sets up a first transverse positioning unit and a longitudinal positioning unit. The U-frame slides along the groove on the adjustment plate through a slider to adapt to different specifications. The longitudinal positioning unit can move and be quickly fixed on the welding table through the cooperation of the insertion column and the insertion hole. With the help of the electric telescopic rod to drive the top plate to lift and adjust the height, it breaks through the limitations of the traditional template positioning spacing and support height being fixed and only able to adapt to a single specification, and improves the adaptability to steel reinforcement cages of different specifications.

[0015] 2. This utility model slidably inserts a screw rod through the top of the clamping rod. The screw rod can act as an operating handle to drive the clamping rod to rotate, thereby clamping and positioning the reinforcing bar. After the reinforcing bar is clamped in place, it can also slide laterally and insert into the limiting groove to form a mechanical locking constraint on the U-frame. This effectively prevents the U-frame from shifting along the sliding groove during welding operations, ensuring the accuracy of the reinforcing bar placement. At the same time, after the screw rod is inserted into the limiting groove, it can resist the vibration and impact caused by welding, reinforcing bar alignment, and slag removal operations, suppressing the clamping rod from rotating and loosening due to vibration, maintaining the reliability of the reinforcing bar clamping state, and further improving the welding quality of the reinforcing bar skeleton.

[0027] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0028] This utility model provides a technical solution: Please see Figures 1-10 A template for welding steel reinforcement cages includes a welding station 1, on which a first transverse positioning unit 2 and a longitudinal positioning unit 3 are provided. The first transverse positioning unit 2 and the longitudinal positioning unit 3 have the same structure. The top of the welding station 1 is detachably installed on a second transverse positioning unit 19 located on the opposite side of the longitudinal positioning unit 3. The second transverse positioning unit 19 is used for welding and positioning transverse steel reinforcement. The side of the welding station 1 opposite to the first transverse positioning unit 2 is provided with a support seat for supporting longitudinal steel reinforcement. The first transverse positioning unit 2 includes an adjusting plate 4, on which a sliding groove 5 is opened. A slider 6 is slidably connected in the sliding groove 5. A U-frame 7 is fixed on the slider 6. A clamping rod 8 is threadedly connected to the U-frame 7. A pressure block 9 is fixed at the lower end of the clamping rod 8.

[0029] When using this device for welding steel reinforcement cages, the first transverse positioning unit 2 is used to position and fix one transverse steel reinforcement in the steel reinforcement cage. Since the U-frame 7 is slidably connected to the groove 5 opened in the adjusting plate 4 through the slider 6, the U-frame 7 can slide along the groove 5 on the adjusting plate 4 to any desired position, solving the limitation of the traditional template positioning spacing being fixed and only suitable for a single specification of steel reinforcement cage, and meeting the welding requirements of steel reinforcement cages of different specifications. The transverse steel reinforcement is placed on the U-frame 7, and the clamping rod 8 is rotated. The clamping rod 8 is fed downward along the thread of the U-frame 7, driving the pressure block 9 fixed at its lower end to move downward synchronously until the pressure block 9 presses the transverse steel reinforcement onto the U-frame 7, completing the clamping and positioning of the transverse steel reinforcement.

[0030] Since the longitudinal positioning unit 3 has the same structure as the first transverse positioning unit 2, the above-mentioned fixing operation is repeated using the longitudinal positioning unit 3 to clamp and fix a longitudinal steel bar, and to place the longitudinal steel bar on top of the fixed transverse steel bar. The longitudinal steel bar and the transverse steel bar are in contact with each other at the intersection. At this time, a welding torch can be used to spot weld the intersection to weld and fix the two together. After completing the weld, the longitudinal positioning unit 3 is moved on the welding table 1 to the next welding position along the length direction of the transverse steel bar, and the longitudinal steel bar is fixed again and spot welded. This operation is repeated to evenly weld several longitudinal steel bars along the length direction of the transverse steel bar. Each longitudinal steel bar in the above welding process is supported by a support.

[0031] After all the longitudinal steel bars are welded, the transverse steel bars are positioned on the second transverse positioning unit 19 and moved along the second transverse positioning unit 19 to the U-frame 7 on the opposite side. After the transverse steel bars are clamped and positioned, the U-frame 7 on the longitudinal positioning unit 3 is moved sequentially along the length of the longitudinal steel bars in the same way as above, and several transverse steel bars are welded to the bottom of the longitudinal steel bars in sequence, and finally the welding operation of the entire steel bar skeleton is completed.

[0032] Specifically, a limiting groove 10 is provided on the adjusting plate 4; a screw rod 11 is slidably inserted through the top of the clamping rod 8; the length of the screw rod 11 is greater than the distance between the clamping rod 8 and the limiting groove 10.

[0033] After the U-frame 7 slides along the slide groove 5 of the adjusting plate 4 to the designated position via the slider 6, the operator first uses the screw rod 11 passing through the top of the clamping rod 8 to rotate the clamping rod 8, causing the pressure block 9 to move downwards to clamp the steel bar to be welded, thus completing the steel bar clamping operation. After clamping in place, the angle of the screw rod 11 is slightly adjusted. Relying on the structural feature that the lateral width of the limiting groove 10 is greater than the diameter of the screw rod 11, and the presence of an elastic rubber pad at the bottom of the pressure block 9, the screw rod 11 can be aligned with the limiting groove 10 through the elastic deformation of the elastic rubber pad during rotation. Then, the screw rod 11 is moved laterally inside the clamping rod 8, so that the screw rod 11 is inserted into the limiting groove 10 opened on the adjusting plate 4, thereby forming a mechanical limit on the U-frame 7, preventing the U-frame 7 from shifting along the slide groove 5 under the action of external force during welding, and ensuring the stability of the steel bar positioning position.

[0034] After the screw rod 11 is inserted into the limiting groove 10 to achieve locking, it can also resist the vibration generated by welding, rebar straightening and slag removal operations, reduce the probability of the clamping rod 8 rotating due to vibration and causing the rebar clamping to loosen, and ensure that the rebar clamping force is continuously effective.

[0035] Specifically, the adjusting plate 4 on the first transverse positioning unit 2 is fixed on the welding station 1; the adjusting plate 4 of the longitudinal positioning unit 3 is fixed with a plug 12; the welding station 1 is provided with a socket 13 for the plug 12 to be inserted.

[0036] The adjusting plate 4 of the first transverse positioning unit 2 is fixedly mounted on the welding station 1, providing a stable and unchanging positioning reference for the welding of the reinforcing bar cage. The longitudinal positioning unit 3 is movably mounted on the welding station 1, and can flexibly move along the length of the transverse reinforcing bars on the welding station 1 according to the design dimensions and spacing requirements of different specifications of reinforcing bar cages. This effectively overcomes the shortcomings of traditional template positioning plates and support spacing that are fixed and can only adapt to a single specification of reinforcing bar cage. The bottom of the adjusting plate 4 of the longitudinal positioning unit 3 is fixed with a column 12, and the welding station 1 has corresponding insertion holes 13 along the moving direction of the longitudinal positioning unit 3. When the longitudinal positioning unit 3 moves to the target welding position, the column 12 is aligned and... The longitudinal positioning unit 3 can be quickly positioned and fixed on the welding station 1 by inserting it into the corresponding hole 13 and using the insertion of the insert post 12 into the hole 13. The operation is simple and the positioning is reliable. It effectively prevents the longitudinal positioning unit 3 from shifting during the welding process and ensures the spacing accuracy and welding quality between the steel bars of the steel reinforcement cage. When it is necessary to adjust the position of the longitudinal positioning unit 3, simply pull the insert post 12 out of the hole 13 to unlock it. Then the longitudinal positioning unit 3 can be moved to the next target position and fixed again by inserting the insert post 12 into the hole 13. This enables the longitudinal positioning unit 3 to be quickly switched and reliably fixed between different welding positions on the welding station 1.

[0037] The length of the insertion post 12 is greater than the depth of the insertion hole 13, and the lower end of the insertion post 12 extends out of the bottom of the insertion hole 13.

[0038] Since the length of the insertion post 12 is greater than the depth of the insertion hole 13, the lower end of the insertion post 12 extends downward from the bottom of the insertion hole 13. When it is necessary to adjust the height of the longitudinal positioning unit 3, the electric telescopic rod 16 fixed on the base plate 15 is activated, driving the top plate 17 to move vertically upward along the guide post 18. During the upward movement, the top plate 17 contacts the lower end of the insertion post 12 and lifts the insertion post 12 upward. The insertion post 12 drives the longitudinal positioning unit 3, which is fixedly connected to it, to rise synchronously, so that the overall height of the longitudinal positioning unit 3 is higher than the first transverse positioning unit 2 fixed on the welding station 1. This allows the longitudinal steel bars clamped on the longitudinal positioning unit 3 to be placed on the transverse steel bars clamped on the first transverse positioning unit 2. The transverse and longitudinal steel bars are intersected in a cross shape at the intersection, which facilitates the spot welding operation of the welding gun at the intersection. At the same time, the adjustable height of the longitudinal positioning unit 3 can adapt to the cross-stacking requirements of steel bars of different diameters, breaking through the limitations of the traditional fixed height of the template support and only being able to adapt to a single specification of steel bar skeleton, further improving the adaptability of the device to steel bar skeletons of different specifications.

[0039] Specifically, support columns 14 are fixed at the four corners of the bottom of the welding station 1, and a base plate 15 is fixed at the lower end of the support columns 14; an electric telescopic rod 16 is fixed on the base plate 15, and a top plate 17 is fixed at the output end of the electric telescopic rod 16; guide columns 18 are slidably inserted at the four corners of the top plate 17, and the lower end of the guide columns 18 is fixed to the base plate 15.

[0040] Support columns 14 are fixed at the four corners of the bottom of the welding station 1. A base plate 15 is fixed to the lower end of each support column 14. The support columns 14 support the welding station 1 to a certain height, creating an operating space between the welding station 1 and the base plate 15 for the installation and operation of the lifting mechanism. Simultaneously, the support columns 14 at the four corners ensure the stability and balance of the welding station 1, preventing it from shaking during welding. An electric telescopic rod 16 is fixed to the base plate 15. A top plate 17 is fixed to the output end of the electric telescopic rod 16. When the electric telescopic rod 16 extends or retracts, it drives the top plate 17 to vertically rise and fall within the space between the welding station 1 and the base plate 15. When the top plate 17 rises, it can lift the insertion post 12 extending from the bottom of the insertion hole 13, thereby driving the longitudinal positioning unit 3 to rise, realizing the height difference adjustment between the longitudinal positioning unit 3 and the first transverse positioning unit 2; guide posts 18 are slidably connected at the four corners of the top plate 17. The guide posts 18 are fixed between the bottom plate 15 and the top plate 17. The guide posts 18 play a guiding and constraining role on the lifting and lowering movement of the top plate 17, ensuring that the top plate 17 always remains in a horizontal state without tilting during the lifting and lowering process, ensuring that the lifting force of the top plate 17 on the insertion post 12 is uniform and stable, so that the height adjustment of the longitudinal positioning unit 3 is smooth and reliable.

[0041] Specifically, the second lateral positioning unit 19 includes an adjustment plate 4, on which a sliding groove 5, a moving channel 20 above the sliding groove 5, and a limiting groove 10 above the moving channel 20 are provided. The bottom of the adjustment plate 4 is fixed with a plug 12 that cooperates with the insertion hole 13. It should be noted that the length of the plug 12 on the second lateral positioning unit 19 is less than the depth of the insertion hole 13.

[0042] The second lateral positioning unit 19 also includes a lateral positioning component 21; wherein, the lateral positioning component 21 includes a slider 6 slidably disposed in the slide groove 5, a support frame 22 fixed on the slider 6, a guide opening provided on one side of the support frame 22, and guide members 23 fixed on opposite sides of the guide opening; a lifting rod 24 is threadedly connected to the top of the support frame 22, a pressure block 9 is fixed to the bottom of the lifting rod 24, a screwing part 25 is fixed to the top of the lifting rod 24, and a screw rod 11 that cooperates with the limiting groove 10 is slidably passed through the screwing part 25.

[0043] A reinforcing bar carrier plate 26 is slidably provided inside the guide opening. The top surface of the reinforcing bar carrier plate 26 is at the same height as the bottom surface of the U-frame 7 on the first transverse positioning unit 2, so that the height of the transverse reinforcing bar at the top of the reinforcing bar carrier plate 26 is the same as the height of the transverse reinforcing bar at the bottom surface of the U-frame 7 clamped on the first transverse positioning unit 2. The reinforcing bar carrier plate 26 is provided with guide channels 27 that slide with the guide member 23 on opposite sides. The top of the reinforcing bar carrier plate 26 is symmetrically provided with horizontal channels 28, and the guide opening is provided with vertical openings 29 on opposite sides.

[0044] The support frame 22 has lifting plates 30 on both sides. A support shaft passing through the vertical opening 29 is fixed on one side of the lifting plate 30. A limiting guide wheel 31 is rotatably provided at the end of the support shaft. A steel bar limiting plate 32 that cooperates with the horizontal channel 28 is fixed at the end of the limiting guide wheel 31. A guide rod 33 that slides through the support frame 22 is fixed at the top of the lifting plate 30. A return spring 34 connected to the support frame 22 is provided at the top of the lifting plate 30.

[0045] A guide wheel limiting seat 35 is symmetrically fixed on the top side of the steel bar carrier plate 26 away from the welding station 1. The top of the guide wheel limiting seat 35 is provided with a limiting groove 36. The guide wheel limiting seat 35 is provided with curved guide surfaces 37 on opposite sides. Initially, the connecting plate connected to the top of the guide rod 33 abuts against the top of the support frame 22. At this time, the bottom surface of the limiting guide wheel 31 is at the same height as the top surface of the steel bar carrier plate 26.

[0046] After all the longitudinal reinforcing bars have been welded, the longitudinal positioning unit 3 is now in a position where... Figure 1At the indicated position, the rebar carrier plate 26 is pushed towards the longitudinal positioning unit 3, causing the limiting guide wheel 31 to roll along the top surface of the rebar carrier plate 26. When the rebar carrier plate 26 moves to the designated position, the limiting guide wheel 31 rolls upward along the curved guide surface 37 and compresses the return spring 34. After the limiting guide wheel 31 rolls away from the curved guide surface 37, it moves downward into the limiting groove 36 with the help of the elastic restoring force of the return spring 34, thus limiting the position of the rebar carrier plate 26. At this time, the rebar carrier plate 26 is close to the U-frame 7 on the longitudinal positioning unit 3. When adjusting the U-frame 7 on the longitudinal positioning unit 3 to the welding position, the rebar carrier plate 26 on the support frame 22 is adjusted to the same welding position, and a transverse steel bar is placed... The transverse reinforcing bar is placed between two reinforcing bar limiting discs 32 on the reinforcing bar carrier plate 26, and pushed until one end of the transverse reinforcing bar is inside the U-frame 7 on the longitudinal positioning unit 3, and the other end is directly below the lifting rod 24 (this end is outside the guide opening). The clamping blocks 9 on the longitudinal positioning unit 3 and the lifting rod 24 are used to clamp and fix the end of the transverse reinforcing bar in the same way. After spot welding the transverse reinforcing bar to each longitudinal reinforcing bar, the U-frame 7 and the support frame 22 on the longitudinal positioning unit 3 are moved sequentially along the length of the longitudinal reinforcing bar in the same way as described above, and several transverse reinforcing bars are welded to the bottom of the longitudinal reinforcing bars in sequence, finally completing the welding operation of the entire reinforcing bar skeleton. It should be noted that after spot welding a transverse reinforcing bar to each longitudinal reinforcing bar, when moving the support frame 22 to adjust the position, the position of the reinforcing bar carrier plate 26 is kept still (i.e., there is no need to pull the reinforcing bar carrier plate 26 outward to return to the initial position), and the next transverse reinforcing bar can be placed directly, which further improves the processing efficiency of the reinforcing bar skeleton.

[0047] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
