[0001] This invention relates to the field of steel bar welding technology, and specifically to a method for double-sided welding of the steel bar skeleton of a cap beam. Background Technology

[0002] Currently, the steel reinforcement cage used for cap beams generally includes straight steel bars on both sides and S-shaped bent steel bars in the middle. The contact points between the straight steel bars and the bent steel bars need to be welded and fixed.

[0003] In traditional techniques, U-shaped locking blocks are installed on the surface of the mold table. The contact points between the straight and bent reinforcing bars are positioned within the locking blocks and clamped together using lateral pressure. Since the contact points between the straight and bent reinforcing bars require welding on both sides, after welding the upper surface, the straight and bent reinforcing bars need to be removed from the locking blocks, flipped, reinstalled, and the other side welded. However, the internal stress generated during welding due to heat and cooling causes deformation in both the straight and bent reinforcing bars. Therefore, flipping and reinstalling the reinforcing bar cage is time-consuming and labor-intensive for workers. Summary of the Invention

[0044] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0045] Reference Figure 1 The reinforcing steel cage 0 of the cap beam includes straight reinforcing bars 01 on both sides and S-shaped bent reinforcing bars 02 in the middle. The contact position between the straight reinforcing bars 01 and the bent reinforcing bars 02 is the welding part 001. The straight reinforcing bars 01 include a first straight reinforcing bar 011 and a second straight reinforcing bar 012, which are arranged in parallel.

[0046] Reference Figures 1 to 15 This embodiment provides a method for double-sided welding of the reinforcing steel cage of a cap beam, which employs a welding fixing device and welding equipment.

[0047] Reference Figures 2 to 3 The welding fixing device includes a support plate 1, several first limiting members 2, and several second limiting members 3. Welding grooves 11 are provided on both sides of the support plate 1, the width of which is adapted to the width of the part to be welded 001, for example, the width of the welding groove 11 = the width of the part to be welded 001 + 10 cm. Support parts 12 are provided on both sides of the welding grooves 11, supporting the first limiting members 2. The first limiting members 2 are rotatably mounted on the support plate 1 inside the welding grooves 11. The first limiting members 2 have a first limiting hole 201, a second limiting hole 202, and a connecting structure 203, which is detachably connected to the support parts 12. The second limiting members 3 are located on both sides of the support plate 1, alternating with the first limiting members 2.

[0048] The double-sided welding method for the reinforcing steel cage of the cap beam also includes the following steps.

[0049] S1 flips the first limiting member 2 to the direction opposite to the welding groove 11 (refer to...). Figure 4 );

[0050] S2 installs the two straight steel bars 01 of the cap beam reinforcement cage 0 into the second limiting members 3 at the two side edges of the support plate 1 (refer to...). Figure 5 );

[0051] S3 places the bent reinforcing bars 02 of the cap beam reinforcement cage 0 between two straight reinforcing bars 01, and suspends the weldable part 001 of the cap beam reinforcement cage 0 in the welding groove 11 or above the welding groove 11 (refer to...). Figure 5 );

[0052] S4 flips the first limiting member 2 to face the welding groove 11, so that the first limiting hole 201 is engaged with the surface of the bent rebar 02 and the second limiting hole 202 is engaged with the surface of the straight rebar 01 (refer to...). Figure 5 );

[0053] S5 connects the connecting structure 203 to the support part 12, so that the first limiting member 2 locks the weldable part 001 of the cap beam steel reinforcement skeleton 0 (refer to...). Figure 5 );

[0054] S6 uses welding equipment to weld the required welding parts 001 of the cap beam reinforcement cage 0 (refer to...). Figure 5 For example, welding can be done simultaneously on both sides or sequentially on both sides.

[0055] Welding equipment, such as welding torches driven by robotic arms, is a standard existing technology in the industry and will not be described in detail here.

[0056] Reference Figure 2 The welding grooves 11 on the same side of the support plate 1 are arranged in a straight array, while the welding grooves 11 on the opposite side of the support plate 1 are arranged in an S-shape.

[0057] Reference Figure 3 The first limiting member 2 has a U-shaped rod-like or plate-like structure.

[0058] Reference Figure 3The first limiting member 2 includes a horizontal pressing member 21 and side pressing members 22 respectively disposed on both sides of the horizontal pressing member 21. The horizontal pressing member 21 and the side pressing members 22 are fixedly connected (e.g., by welding, bolting, or integral molding). A first limiting hole 201 and a second limiting hole 202 are disposed on the lower surface of the side pressing member 22. The diameter and inclination angle of the first limiting hole 201 are adapted to the bent reinforcing bar 02, and the diameter and inclination angle of the second limiting hole 202 are adapted to the straight reinforcing bar 01. A connecting structure 203 is disposed at the end of the side pressing member 22 away from the horizontal pressing member 21. The connecting structure 203 includes a mechanical connecting assembly or a magnetic connecting assembly.

[0059] Reference Figure 2 and 6 The mechanical connection assembly includes a locking bolt 2031 that is threadedly connected to the side pressure member 22. The side pressure member 22 has a support screw hole, and the locking bolt 2031 is placed in the support screw hole and engaged by the thread. When the locking bolt 2031 rotates in the support screw hole, it can achieve axial expansion and contraction. The support part 12 has a locking screw hole that mates with the locking bolt 2031. When the operator rotates the locking bolt 2031 until the thread of the locking bolt 2031 is screwed into the locking screw hole, the mechanical connection assembly is connected to the support part 12. When the operator rotates the locking bolt 2031 until the thread of the locking bolt 2031 is screwed out of the locking screw hole, the mechanical connection assembly is separated from the support part 12.

[0060] Reference Figure 2 and 7 The magnetic connection component is a magnetic fixing box 2032. The specific structure of the magnetic fixing box 2032 is conventional existing technology in the industry and will not be described in detail. When using the magnetic fixing box 2032, the support plate 1 is made of steel plate. The magnetic fixing box 2032 is fixedly connected to the side pressure member 22, for example, by bolts. When the switch of the magnetic fixing box 2032 is turned on, the magnetic fixing box 2032 is attracted to the surface of the support part 12 to achieve connection; when the switch of the magnetic fixing box 2032 is turned off, the magnetic fixing box 2032 is separated from the surface of the support part 12.

[0061] Reference Figure 6 The horizontal pressure member 21 is connected to the rotating shaft 204 / sleeve 205. When the horizontal pressure member 21 is fixedly connected to the rotating shaft 204 (e.g., fixed with bolts), the sleeve 205 is fixedly connected to the support plate 1, and the rotating shaft 204 is placed inside the sleeve 205 and rotatably connected; when the horizontal pressure member 21 is connected to the sleeve 205, the rotating shaft 204 is fixedly connected to the support plate 1, and the rotating shaft 204 is placed inside the sleeve 205 and rotatably connected.

[0062] Reference Figures 8 to 10The second limiting member 3 includes a lower limiting member and an upper limiting member. The lower limiting member has a longitudinal receiving groove 210 in the middle, which is used to receive the straight rebar 01. The lower limiting member has a transverse insertion groove 211 in the middle of its side wall, which is connected to and perpendicular to the receiving groove 210. The upper limiting member has an n-shaped plate structure, and the inner surface of the upper limiting member has an insertion protrusion 221, which is inserted into the insertion groove 211. When the upper limiting member is inserted into the lower limiting member, the lower surface of the upper limiting member and the lower part of the receiving groove 210 together form a receiving space with a rectangular cross-section and open at both ends. The straight rebar 01 is placed in the receiving space, and the lower surface of the upper limiting member is pressed against the surface of the straight rebar 01. The receiving grooves 210 of the second limiting member 3 located on the same side of the support plate 1 are on the same straight line, that is, the corresponding receiving spaces are on the same straight line. Therefore, the second limiting member 3 can install the straight rebar 01 and ensure the straightness of the straight rebar 01.

[0063] Reference Figures 8 to 10 The bottom surface of the inner cavity of the receiving groove 210 is coplanar with the surface of the support plate 1. For example, an embedded groove is opened on the surface of the support plate 1, and the lower limiting member is placed in the embedded groove and fixedly connected (e.g., by bolt fastening).

[0064] Reference Figures 8 to 10 The second limiting member 3 also includes a pin 23. The top surface of the lower limiting member has a first insertion hole 212, and the upper limiting member has a second insertion hole 222. The first insertion hole 212 and the second insertion hole 222 are adapted to each other, and the pin 23 is inserted into the first insertion hole 212 and the second insertion hole 222. In use, the worker places the straight steel bar 01 in the receiving groove 210, inserts the upper limiting plate into the upper part of the lower limiting plate, and aligns the first insertion hole 212 and the second insertion hole 222; then, the pin 23 is vertically inserted into the first insertion hole 212 and the second insertion hole 222 to prevent the upper limiting plate from sliding off the lower limiting plate. The pin 23 has external threads, and the second insertion hole 222 has internal threads. The pin 23 can be locked in the second insertion hole 222 through the external threads.

[0065] The support plate 1 can be set horizontally, vertically, or at an angle.

[0066] Reference Figure 11The support plate 1 is horizontally mounted on the upper surface of the mold table 101, and the support plate 1 is connected to the mold table 101 by bolts or welding. The mold table 101 includes a support base 1011, a first reinforcing rib 1012, and a second reinforcing rib 1013. The mold table 101 is located in the middle of the bottom surface of the support plate 1, and the edge structure of the mold table 101 at the welding groove 11 position does not exceed the inner edge of the welding groove 11, avoiding the edge structure of the mold table 101 from extending outward, and further avoiding the edge structure from covering the welding part 001 of the cap beam steel reinforcement skeleton 0, ensuring that the welding part 001 is exposed and easy to weld. The first reinforcing rib 1012 is provided between the support part 12 and the side of the support base 1011 to improve the load-bearing capacity of the support part 12; the second reinforcing rib 1013 is provided between the support plate 1 inside the welding groove 11 and the side of the support base 1011 to improve the load-bearing capacity of the welding groove 11 and the support plate 1 around the welding groove 11. In use, the reinforcing steel cage 0 of the cap beam is laid flat on the upper surface of the support plate 1, and the welding parts 001 of the reinforcing steel cage 0 are suspended in or above the welding groove 11. The workers perform double-sided welding on the welding parts 001 of the reinforcing steel cage 0, for example, by using a double-head welding device to weld on both sides simultaneously, or by using a single-head welding device to weld on both sides sequentially.

[0067] Reference Figure 11 The support plate 1 adopts an integral plate structure, for example, the support plate 1 is made of a whole steel plate.

[0068] Reference Figures 12 to 13 The support plate 1 adopts a spliced ​​plate structure, for example, the support plate 1 is composed of several support modules spliced ​​together, and the support modules are filled with a joint filler plate 1014. The joint filler plate 1014 is detachably connected to the support module with bolts. The joint filler plates 1014 of different sizes provide different distances between the welding grooves 11, between the first limiting members 2, and between the second limiting members 3, which are used to fix the cap beam reinforcement skeleton 0 of different sizes.

[0069] Reference Figure 14 The support plate 1 is inclinedly mounted on the bracket 102. The bracket 102 includes a base 1021 and a back rod 1022 that are welded together. The back rod 1022 is connected to the back of the support plate 1 (e.g., by lap or welding). The cap beam reinforcement skeleton 0 is laid on the surface of the support plate 1. The welding parts 001 of the cap beam reinforcement skeleton 0 are suspended in the welding groove 11 or on the side of the welding groove 11. After assembly, the workers perform double-sided welding on the welding parts 001 of the cap beam reinforcement skeleton 0.

[0070] Reference Figure 15The support plate 1 is vertically mounted on the bracket '102', which includes a base 1021 and support rods 1023. The support rods 1023 are located on both sides of the support plate 1 to provide support. The cap beam reinforcement cage 0 is laid on the surface of the support plate 1. The weldable parts 001 of the cap beam reinforcement cage 0 are suspended in the welding groove 11 or on the side of the welding groove 11. After assembly, the workers perform double-sided welding on the weldable parts 001 of the cap beam reinforcement cage 0.

[0071] This invention utilizes the welding groove 11 of the support plate 1 to suspend the weldable part 001 of the cap beam steel reinforcement skeleton 0, exposing the left and right sides of the weldable part 001 of the cap beam steel reinforcement skeleton 0, thereby facilitating welding and avoiding the problem of workers needing to flip and reinstall in traditional technology, simplifying the operation steps and reducing the welding difficulty. Compared with traditional technology, this invention can reduce the number of times the cap beam steel reinforcement skeleton 0 is disassembled and assembled, while avoiding installation errors caused by multiple disassemblies and assemblies, and improving processing efficiency and accuracy.

[0072] Welding equipment, for example, uses a welding torch driven by a single-sided robotic arm 5 for single-sided overhead welding, which is more convenient to operate and has a lower cost compared to double-sided "overhead welding" and double-sided "vertical welding".

[0073] Reference Figure 16 A flip hinge 4 (e.g., connected by bolts or by welding) is provided at the side edge of the support plate 1, and several sleepers 41 are provided on both sides of the flip hinge 4; the flip hinge 4 and the sleepers 41 together support the support plate 1 and keep the support plate 1 in a horizontal state.

[0074] Reference Figure 16 and 17 During welding, the support plate 1 is placed on the flip hinge 4 and the sleeper 41, with the side of the support plate 1 equipped with the first limiting member 2 and the second limiting member 3 facing upwards; the straight reinforcing bar 01 and the bent reinforcing bar 02 are installed using the first limiting member 2 and the second limiting member 3, and the single-sided robotic arm 5 is activated to drive the welding torch to perform downward welding on the upward-facing side of the cap beam reinforcing bar skeleton 0 (refer to...). Figure 16 Then, using manual labor or a flipping device, the support plate 1 and the cap beam reinforcement cage 0 are flipped 180° along the flipping hinge 4. The support plate 1 is then supported to a horizontal position using the flipping hinge 4 and the sleeper 41 on the other side. The single-sided robotic arm 5 is then activated to drive the welding torch to perform downward welding on the upward-facing side of the cap beam reinforcement cage 0 (see reference). Figure 17 The welding torch passes through the welding groove 11 to weld the upward-facing side of the cap beam reinforcement skeleton 0. After two downward welds, the support plate 1 and the cap beam reinforcement skeleton 0 are manually or using a flipping device to flip them 180° in the opposite direction along the flipping hinge 4, so that the side of the support plate 1 with the first limiting member 2 and the second limiting member 3 faces upward. Finally, the welded cap beam reinforcement skeleton 0 is removed from the first limiting member 2 and the second limiting member 3. (Refer to...)Figures 16 to 17 This technical solution can be applied to a long-arm single-sided robotic arm 5. For example, when the maximum arm span of the single-sided robotic arm 5 is greater than the width of the cap beam steel reinforcement skeleton 0 × 2, it is considered a long-arm single-sided robotic arm 5.

[0075] Reference Figures 16 to 17 The support plate 1 is fixedly connected to a flipping pull ring 6 on the opposite side of the flipping hinge 4 (e.g., by welding or bolting). The flipping pull ring 6 facilitates the operator's gripping and connection to the flipping device.

[0076] Reference Figures 18 to 21 The tilting device includes a column 7, a take-up reel 701, a sling 702, a turntable 703, a lever 704, and a lower base plate 71. Two columns 7 are provided, located at opposite ends of the support plate 1, with the bottoms of the two columns 7 aligned with the bottom of the tilting hinge 4. The take-up reel 701 is located on top of the column 7 and rotatably connected. The take-up reel 701 is connected to the tilting pull ring 6 via the sling 702 (or the take-up reel 701 is connected to the support plate 1 on the opposite edge of the tilting hinge 4; for example, the support plate 1 has lifting holes on the opposite edge of the tilting hinge 4, and the sling 702 is connected to the lifting holes via hooks). Tightening the sling 702 with the take-up reel 701 lifts the support plate 1 on the opposite edge of the tilting hinge 4, and extending the sling 702 with the take-up reel 701 slowly lowers the support plate 1 on the opposite edge of the tilting hinge 4. The column 7 is fixedly connected to the lower base plate 71 (e.g., by welding or bolting). Support plate 1 is mounted on the surface of lower base plate 71, and flip hinge 4 is fixed to the surface of lower base plate 71 (e.g., by welding or bolting). Sleeper 41 is also fixed to the surface of lower base plate 71 (e.g., by welding or bolting). (See reference) Figures 18 to 20 When the welding operation requires clockwise rotation of the support plate 1: the take-up reel 701 continuously tightens the sling 702, which lifts the side of the support plate 1 containing the flipping ring 6 until the support plate 1 is nearly vertical. The turntable 703 rotates counterclockwise, and the lever 704 on the turntable 703 moves the support plate 1 to continue rotating until the support plate 1 tilts to the right. Then, the take-up reel 701 slowly extends the sling 702, allowing the support plate 1 to slowly rest on the right-side sleeper 41. While the take-up reel 701 slowly extends the sling 702, the turntable 703 rotates clockwise until the lever 704 returns to its top dead center (the movement path of the lever 704 is circular, and the top dead center of the lever 704 is located at the very top of its circular movement path), preventing the lever 704 from tangling with the sling 702.

[0077] The column 7 is equipped with two built-in motors, which drive the take-up reel 701 and the turntable 703 to rotate independently. The two built-in motors are electrically connected to the external power supply.

[0078] Reference Figures 21 to 24This solution is applicable to short-arm, single-sided robotic arms 5. For example, when the maximum reach of the single-sided robotic arm 5 is less than the width of the reinforcing steel skeleton 0 of the cap beam, it can only weld the welding portion 001 on one side of the reinforcing steel skeleton 0 at a time, and is considered a short-arm, single-sided robotic arm 5. (Refer to...) Figure 22 The welding parts 001 on the two sides of the support plate 1 are welding parts 001A on side A and welding parts 001B on side B.

[0079] Reference Figures 21 to 24 The aforementioned tilting device is employed, and the tilting device further includes a traveling chassis 72. Two traveling chassis 72 are provided, each positioned below one of the two columns 7. The traveling chassis 72 are rotatably connected (e.g., via bearings) to the lower surface of the column 7 or the lower surface of the lower base plate 71. A chassis motor is installed within the traveling chassis 72, driving the drive wheels at the bottom of the traveling chassis 72 to rotate; the rotation of the drive wheels drives the traveling chassis 72 to move; the chassis motor is electrically connected to an external power source. The traveling chassis 72 is mounted on a track 8, which is bolted to the floor of the processing workshop. The track 8 includes a straight track 81 and a turning track 82. The turning track 82 is circular; two straight tracks 81 are provided, arranged parallel to each other, with the distance between the two straight tracks equal to the diameter of the circular turning track 82. The two straight tracks 81 are tangentially fixedly connected to the turning track 82 (e.g., via bolts). The single-sided robotic arm 5 is located at the end of the straight track 81 away from the turning track 82. When both traveling chassis 72 have moved to the end of the straight track 81 away from the turning track 82, the single-sided robotic arm 5 can perform welding operations on the part 001A to be welded on side A (refer to...). Figure 22 After welding of part 001A on side A is completed, the two traveling chassis 72 move towards the steering track 82 and complete a 180° horizontal rotation within the steering track 82, simultaneously driving the lower base plate 71, support plate 1, and cap beam steel reinforcement cage 0 to rotate horizontally by 180° (refer to...). Figure 23 After the horizontal rotation of the cap beam steel reinforcement cage 0 is completed, the two traveling chassis 72 travel synchronously to the end of the straight track 81 away from the turning track 82, so that the part 001B to be welded on side B is close to the single-sided robotic arm 5. At this time, the single-sided robotic arm 5 can be driven to weld the part 001B to be welded on side B.
