Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for steel bar welding, and in particular to a device for assisting in the welding of U-shaped rings and reinforcing bars. Background Technology

[0002] In building construction, cantilevered I-beams are frequently used for external scaffolding. The anchoring points of these cantilevered I-beams typically require the pre-embedded U-shaped rings for securing them. According to specifications, horizontal reinforcing bars must be installed at the bottom of the U-shaped rings. These horizontal reinforcing bars are usually spot-welded to the U-shaped rings and then pre-embedded as a whole. However, without specialized equipment, welding can be inconvenient and inefficient.

[0003] Patent CN212917439U discloses a platform for binding the reinforcing steel skeleton of a precast box girder top slab. It includes at least two support units, two parallel reinforcing steel limiting members, at least two parallel first reinforcing steel support members, and at least one second reinforcing steel support member. Each support unit has a T-shaped structure, and all support units are arranged side-by-side with their projections overlapping. The two reinforcing steel limiting members are respectively connected to the two ends of each support unit in the lateral direction, forming an elongated T-shaped structure. Each first reinforcing steel support member is located between the two reinforcing steel limiting members and is parallel to them. Each first reinforcing steel support member is connected to a support unit. Each first reinforcing steel support member has multiple reinforcing steel positioning grooves distributed at predetermined intervals. All reinforcing steel positioning grooves are aligned in the lateral and longitudinal directions, and the bottom of the grooves, the bottom surface of the reinforcing steel limiting members, and the second reinforcing steel support members are all on the same horizontal plane. This platform can position the reinforcing steel, making the spacing between the reinforcing steel more uniform and improving work efficiency. However, the test bench is only suitable for binding the steel reinforcement cage of the top slab of the precast box girder, and cannot be used for connecting the U-shaped ring and the reinforcing bar at the anchor point of the cantilevered I-beam. It cannot solve the problems of inconvenient operation and low work efficiency of welding the U-shaped ring and the reinforcing bar. Summary of the Invention

[0004] This invention proposes a device for assisting in the welding of U-shaped rings and reinforcing ribs, which solves the problems of inconvenient operation and low connection efficiency in the prior art when connecting U-shaped rings and reinforcing ribs.

[0005] The technical solution of this invention is implemented as follows:

[0006] A device for assisting in welding U-shaped rings and reinforcing ribs includes a support frame with a placement assembly for positioning the U-shaped ring and reinforcing ribs. The placement assembly includes a main support rod connected to the support frame, and a secondary support rod for positioning the U-shaped ring on the main support rod. The secondary support rod is detachably connected to the main support rod. In use, two reinforcing ribs are placed parallel to each other on the secondary support rod, and then the U-shaped ring is inverted onto the reinforcing rib, ensuring it is in contact with the secondary support rod. This positioning of the U-shaped ring by the secondary support rod ensures stable spacing between the U-shaped rings, facilitates welding between the U-shaped ring and reinforcing ribs, and improves welding efficiency.

[0007] The number of main support rods is at least two, and the main support rods are arranged parallel to each other. The two main support rods provide support to both ends of the secondary support rod, ensuring the stability of the secondary support rod during use.

[0008] The main support rod has multiple evenly arranged vertical slots, and the secondary support rods are connected to these slots. The secondary support rods can connect to the vertical slots at different positions according to the different spacing requirements of the U-shaped rings, allowing the device to be adapted to different spacing requirements.

[0009] The main support rod is inclined on the support frame, and a baffle is provided at the lower end of the main support rod, perpendicular to the main support rod. After the reinforcing rib is placed on the secondary support rod, the end of the reinforcing rib contacts the baffle. At this time, the baffle axially positions the reinforcing rib, thereby keeping the distance between each U-shaped ring and the end of the reinforcing rib fixed. This ensures the consistency of the connection between the U-shaped ring and the reinforcing rib, and ensures the accurate position of the U-shaped ring after the pre-embedding of the U-shaped ring and the reinforcing rib, facilitating the subsequent installation of the cantilevered I-beam.

[0010] The lower side of the secondary support rod is provided with an auxiliary support structure to support the U-shaped ring. The support surface of the auxiliary support structure that contacts the U-shaped ring is parallel to the baffle. The auxiliary support structure supports the U-shaped ring so that after the U-shaped ring is placed on the reinforcing rib, the U-shaped ring and the reinforcing rib remain perpendicular to each other.

[0011] The auxiliary support structure includes a connecting rod and a support plate. The upper end of the connecting rod is connected to the secondary support rod, and the support plate is connected to the lower end of the connecting rod. The support plate is flush with the side of the secondary support rod. After the U-shaped ring is placed on the reinforcing rib, the support plate provides support for the lower part of the U-shaped ring, causing the U-shaped ring to tilt, thereby making the U-shaped ring perpendicular to the reinforcing rib.

[0012] The upper side of the secondary support rod is provided with a limiting groove. The limiting groove positions the reinforcing ribs, ensuring that the spacing between each reinforcing rib remains fixed, thereby ensuring the consistency of the connection between the U-shaped ring and the reinforcing ribs.

[0013] The support frame is equipped with a welding rod holder. The welding rod holder is used to hold welding rods, which facilitates the removal and use of welding rods when welding the U-shaped ring to the reinforcing rib, thereby improving work efficiency.

[0014] The support frame includes a horizontally arranged lower rectangular frame and an upper C-shaped frame, which are connected by vertical rods. When welding the U-shaped ring to the reinforcing rib, workers can stand at the opening of the C-shaped frame to perform the welding. The opening of the C-shaped frame allows workers to more easily approach the reinforcing rib and U-shaped ring, reducing the difficulty of the work and improving welding efficiency.

[0015] Both the lower rectangular frame and the upper C-shaped frame include a first horizontal bar and a second horizontal bar, which are connected by a connector. The ends of the vertical bars are also connected to the connectors. The first horizontal bar, the second horizontal bar, and the vertical bars are plugged into the connectors, making assembly and disassembly convenient. One person can complete all assembly and disassembly operations, facilitating the storage and transportation of the device.

[0016] The beneficial effects of this invention are as follows: During device use, two reinforcing ribs are placed parallel to each other on the secondary support rod. Then, a U-shaped ring is inverted on the reinforcing rib and brought into contact with the secondary support rod. The secondary support rod positions the U-shaped ring, ensuring stable spacing and facilitating welding between the U-shaped ring and the reinforcing rib, thus improving welding efficiency. The limiting groove on the secondary support rod radially positions the reinforcing ribs, ensuring a fixed spacing between each reinforcing rib, thereby guaranteeing consistency in the connection between the U-shaped ring and the reinforcing rib. The baffle at the end of the main support rod axially positions the reinforcing rib, keeping the distance between each U-shaped ring and the end of the reinforcing rib fixed. This ensures accurate positioning of the U-shaped ring after pre-embedding with the reinforcing rib, facilitating subsequent installation of the cantilevered I-beam.

[0017] Easy to assemble and disassemble, the components can be easily assembled and bolted together to form a complete device, and one person can complete all disassembly and assembly operations; reusable, the components of this device are all made of structural steel, with a long service life and can be reused; improved welding efficiency, this device can invert the U-shaped rings on the reinforcing steel bars for welding, which is convenient for workers and improves welding efficiency; the spacing of the U-shaped rings can be flexibly adjusted, by cutting interval vertical slots on the angle steel main beam, the appropriate vertical slots can be selected according to the required spacing of the U-shaped rings to meet various spacing requirements.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1, such as Figure 1 , Figure 2 As shown, an auxiliary device for welding U-shaped rings and reinforcing ribs includes a support frame 1. The support frame 1 has a placement assembly 2 for positioning the U-shaped rings and reinforcing ribs. The placement assembly 2 includes a main support rod 21 connected to the support frame 1. The main support rod 21 has a secondary support rod 23 for positioning the U-shaped rings, and the secondary support rod 23 is detachably connected to the main support rod 21. The support frame 1 provides support for the placement assembly 2, ensuring its stability during use. In use, two reinforcing ribs 3 are placed parallel to each other on the secondary support rod 23. Then, the U-shaped ring 4 is inverted onto the reinforcing ribs 3, and the U-shaped ring 4 is brought into contact with the secondary support rod 23, thus positioning the U-shaped ring 4 and ensuring a stable spacing between the U-shaped rings 4. This facilitates welding of the U-shaped ring 4 to the reinforcing ribs 3, improving welding efficiency. The spacing of the U-shaped rings 4 is controlled by the relative position of the secondary support rod 23 on the main support rod 21.

[0026] Furthermore, there are at least two main support rods 21, which are arranged parallel to each other. In this embodiment, there are two main support rods 21, which are connected to the support frame 1 by connecting bolts 15 to ensure that the main support rods 21 are stably installed on the support frame 1. The two main support rods 21 provide support for both ends of the secondary support rod 23, ensuring the stability of the secondary support rod 23.

[0027] Furthermore, the main support rod 21 is provided with multiple evenly arranged vertical slots 22, and the secondary support rod 23 is connected to the vertical slots 22. The secondary support rod 23 can be connected to the vertical slots 22 at different positions according to the different spacing requirements of the U-shaped ring 4, so that the device can be adapted to different spacing requirements.

[0028] Example 2, based on Example 1, provides a device for welding an auxiliary U-shaped ring to a reinforcing rib. The main support rod 21 and the secondary support rod 23 are both angle steel. Specifically, the main support rod 21 has a specification of 50x50x3.0 mm and a length of 2200 mm. The secondary support rod 23 has a specification of 30x30x3.0 mm and a length of 50 mm. A vertical groove, 35 mm high and 4 mm wide, is formed every 50 mm on the vertical portion of the main support rod 21. The vertical edge of the secondary support rod 23 is secured to the angle steel main beam via the vertical groove.

[0029] Furthermore, bolt holes are provided on the horizontal part of the main support rod 21. The bolt holes are located 100mm from the end of the main support rod 21. The bolt holes correspond to the bolt holes on the support frame 1. The connecting bolts 15 pass through the bolt holes to fix the main support rod 21 to the support frame 1.

[0030] Example 3, based on Example 1, provides a device for assisting in the welding of a U-shaped ring to a reinforcing rib, such as... Figure 3 As shown, the main support rod 21 is inclined on the support frame 1, and a baffle 211 is provided at the lower end of the main support rod 21, which is perpendicular to the main support rod 21. After the reinforcing rib 3 is placed on the secondary support rod 23, the end of the reinforcing rib 3 contacts the baffle 211. At this time, the baffle 211 axially positions the reinforcing rib 3, thereby keeping the distance between each U-shaped ring 4 and the end of the reinforcing rib 3 fixed, thus ensuring the consistency of the connection between the U-shaped ring 4 and the reinforcing rib 3, and ensuring the accurate position of the U-shaped ring 4 after the pre-embedding of the U-shaped ring 4 and the reinforcing rib 3, which facilitates the subsequent installation of the cantilevered I-beam.

[0031] In addition, the inclined arrangement of the main support rod 21 allows the contact position of the reinforcing rib 3 and the U-shaped ring 4 to be tilted upwards, making it easier for workers to find the accurate welding point during welding. During the welding process, workers do not need to tilt their heads to observe the contact position of the reinforcing rib 3 and the U-shaped ring 4, reducing the difficulty of welding operations, reducing the construction intensity of workers, and improving welding efficiency.

[0032] Furthermore, such as Figure 4 As shown, the lower side of the secondary support rod 23 is provided with an auxiliary support structure to support the U-shaped ring 4. The support surface of the auxiliary support structure that contacts the U-shaped ring 4 is parallel to the baffle 211. The auxiliary support structure provides support for the U-shaped ring 4, so that after the U-shaped ring 4 is placed on the reinforcing rib 3, the U-shaped ring 4 and the reinforcing rib 3 remain perpendicular to each other.

[0033] Furthermore, the auxiliary support structure includes a connecting rod 232 and a support plate 233. The upper end of the connecting rod 232 is connected to the secondary support rod 23, and the support plate 233 is connected to the lower end of the connecting rod 232. The support plate 233 is flush with the side of the secondary support rod 23. After the U-shaped ring 4 is placed on the reinforcing rib 3, the support plate 233 provides support for the lower part of the U-shaped ring 4, causing the U-shaped ring 4 to tilt, thereby making the U-shaped ring 4 perpendicular to the reinforcing rib 3. In this embodiment, the secondary support rods 23 are arranged in the same direction, that is, when the main support rod 21 is tilted, the opening of the secondary support rod 23 faces downward. When the U-shaped ring 4 contacts the secondary support rod 23, the U-shaped ring 4 directly contacts the vertical part of the secondary support rod 23.

[0034] Furthermore, a limiting groove 231 is provided on the upper side of the secondary support rod 23. The secondary support rod 23 has multiple evenly arranged limiting grooves 231. Depending on the different usage requirements of the cantilevered I-beam, the main support rod 21 can be placed into limiting grooves with different spacing. In this embodiment, the secondary support rod 23 has two limiting grooves 231. After the reinforcing rib 3 is placed on the secondary support rod 23, the reinforcing rib 3 is located within the limiting groove 231. The limiting groove 231 positions the reinforcing rib 3, ensuring that the spacing between each reinforcing rib 3 remains fixed, thereby ensuring the consistency of the connection between the U-shaped ring 4 and the reinforcing rib 3.

[0035] Furthermore, the support frame 1 is equipped with a welding rod cylinder 16. The welding rod cylinder 16 is used to hold welding rods, which facilitates the removal and use of welding rods when welding the U-shaped ring 4 to the reinforcing rib 3, thereby improving work efficiency.

[0036] Example 4 differs from Example 3 in that it includes an auxiliary device for welding the U-shaped ring and the reinforcing rib, wherein the inclination angle of the main support rod 21 is 0 to 30 degrees. In this example, the inclination angle of the main support rod 21 is 3 degrees, and the left end of the main support rod 21 is lower than the right end of the main support rod 21. The baffle 211 is located at the left end of the main support rod 21. After the reinforcing rib 3 is placed on the secondary support rod 23, its end contacts the baffle 211 under its own weight. After the U-shaped ring 4 is inverted on the reinforcing rib 3, the U-shaped ring 4 slides down and contacts the secondary support rod 23. The lower part of the U-shaped ring 4 contacts the auxiliary support structure, making the U-shaped ring 4 perpendicular to the reinforcing rib 3.

[0037] Furthermore, a pad is provided at the lower part of the main support rod 21, or the left and right sides of the support frame 1 are at different heights. The inclination of the main support rod 21 can be changed by setting a pad or adjusting the height of the support frame 1. In this embodiment, the two sides of the support frame 1 are at the same height, and a pad is provided at the lower right end of the main support rod 21. The pad is located between the main support rod 21 and the support frame 1. The pad raises the right end of the main support rod 21, thereby achieving the inclination of the main support rod 21.

[0038] Example 5, based on Example 1, provides an auxiliary device for welding a U-shaped ring to a reinforcing rib. The support frame 1 includes a horizontally arranged lower rectangular frame and an upper C-shaped frame, connected by a vertical rod 14. When welding the U-shaped ring 4 to the reinforcing rib 3, the worker can stand at the opening of the C-shaped frame to perform the welding. The opening of the C-shaped frame allows the worker to more easily approach the reinforcing rib 3 and the U-shaped ring 4, reducing the difficulty of the work and improving welding efficiency.

[0039] Furthermore, both the lower rectangular frame and the upper C-shaped frame include a first horizontal bar 11 and a second horizontal bar 13, which are connected by a connector 12. The end of the vertical bar 14 is connected to the connector 12. The first horizontal bar 11, the second horizontal bar 13, and the vertical bar 14 are respectively plugged into the connector 12, making disassembly and assembly convenient. One person can complete all disassembly and assembly operations, facilitating the storage and transportation of the device.

[0040] Example 6, based on Example 5, provides a device for assisting in the welding of a U-shaped ring and reinforcing ribs. The first horizontal bar 11, the second horizontal bar 13, and the vertical bar 14 are all square tubes with dimensions of 40x40x2.5 mm. The first horizontal bar 11 is 2000 mm long, the second horizontal bar 13 is 1000 mm long, and the vertical bar 14 includes an upper vertical bar, a middle vertical bar, and a lower vertical bar. The upper vertical bar is 300 mm long, the middle vertical bar is 600 mm long, and the lower vertical bar is 400 mm long. The connecting piece 12 is made of welded steel pipe. The first horizontal bar 11, the second horizontal bar 13, and the vertical bar 14 are all inserted into the connecting piece 12, enabling rapid assembly and disassembly of the device and facilitating its use.

[0041] Furthermore, the end of the main support rod 21 is connected to the second crossbar 13, and the second crossbar 13 is provided with bolt holes. The connecting bolt 15 passes through the horizontal part of the main support rod 21 and is connected to the bolt holes.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
