Technical Field

[0001] The utility model relates to the technical field of steel structure manufacturing, in particular to a welding node of a box-type steel beam. Background Art

[0002] In large-scale steel structure projects, box-type steel beams are widely used due to their good rigidity and load-bearing capacity. However, the welding of the lower flange of box-type steel beams often faces the problems of narrow operating space and poor welding position, which not only increases the difficulty of welding and reduces the welding quality, but also may cause welding deformation, welding cracks and other problems, affecting the overall safety and stability of the structure. In traditional methods, the overhead welding operation of the lower flange is not only time-consuming, but also requires extremely high skills of the welder, making it difficult to ensure the consistency and reliability of the welding quality. Summary of the invention

[0003] In order to overcome the defects in the prior art, a welding node of a box-type steel beam with simple structure, high welding efficiency and convenient operation is provided.

[0004] The technical solution of the utility model is as follows: a welding node of a box-type steel beam, including a steel column, a steel corbel and a steel beam; one end of the steel corbel is assembled on the steel column, and the other end is connected to the steel beam; a welding structure for welding the lower flange between the steel beam and the steel corbel is provided on the steel beam, and a positioning structure for connecting the steel corbel is fixed on the steel beam. The welding structure solves the problem of overhead welding of the lower flange between the steel beam and the steel corbel, and improves the welding quality and efficiency; the positioning structure improves the installation efficiency of the entire box-type steel beam.

[0005] Preferably, the welding structure is a welding hole and a connecting plate formed on the steel beam, and the connecting plate is assembled on the welding hole. The welding hole and the connecting plate make the installation process simpler and more efficient, reduce the installation steps and the required tools, and improve the construction efficiency.

[0006] Preferably, the welding hole is opened on the steel beam near one end of the steel bracket, so that the operator can get closer to the welding point during welding and improve the welding efficiency.

[0007] Preferably, the steel beam includes a top plate, a bottom plate and a side plate; the top plate and the bottom plate are connected by the side plate, and welding holes are provided on the side plate where the side plate and the bottom plate are connected. The position of the welding holes provides enough space for the operator to complete the welding of the lower flange in a flat welding manner, thereby avoiding the difficult overhead welding operation.

[0008] Preferably, a welding lining strip for welding the connecting plate is provided on the welding hole, thereby improving the welding quality and making the connection between the connecting plate and the steel beam more firm.

[0009] Preferably, multiple positioning structures are provided, which are evenly arranged on the upper surface of the end of the steel beam, so that the steel beam can be positioned more accurately during the installation process; the uniform distribution can ensure that the positional relationship between the steel beam and the steel corbel is accurate during assembly, thereby improving the installation accuracy of the entire structure.

[0010] Preferably, a positioning groove is provided in the middle of the bottom of the positioning structure, and the two sides of the positioning groove are respectively a welding part and abutting part. With the guidance of the positioning groove, the operator can quickly and accurately complete the installation of the positioning structure, simplifying the installation process and improving the construction efficiency.

[0011] Preferably, the bottom of the welding part is welded to the steel beam, and the bottom of the abutting part abuts against the steel corbel. The bottom of the abutting part abuts tightly against the steel corbel, so that the steel beam can be accurately butted against the steel corbel. This simplifies the installation process, improves the installation accuracy, and reduces installation problems caused by position deviation.

[0012] Preferably, the welding portion is provided with a hoisting hole for hoisting the steel beam, thereby improving the installation efficiency of the steel beam and improving the safety during hoisting.

[0013] Preferably, the positioning groove is located at the joint of the steel corbel and the steel beam. The positioning groove ensures accurate docking between the steel beam and the steel corbel, reduces adjustment time during installation, and improves installation accuracy.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] A welding node for a box-type steel beam solves the problem of overhead welding of the lower flange between the steel beam and the steel corbel through a welding structure, thereby improving welding quality and efficiency; the specific opening position of the welding hole makes the welding process more stable and easy to control the welding heat input, which significantly improves the welding quality and efficiency and reduces weld defects.

[0016] Furthermore, by closing the welding holes with connecting plates, it is ensured that the structural strength and sealing performance after closure are not lower than the original structure, thus ensuring the stability of the entire structure.

[0017] Furthermore, the installation efficiency of the entire box-type steel beam is improved by the positioning structure, so that the steel beam is overlapped and positioned with the steel corbel during assembly, solving the problem of having to hoist the steel beam all the time during welding.

DETAILED DESCRIPTION

[0026] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0027] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0028] like Figures 1 to 4 As shown, a welding node of a box-type steel beam, a welding node composed of a steel column 1, a steel bracket 2 and a steel beam 3, can significantly improve the strength and stability of the entire structure through precise design and welding technology. This structure can withstand greater load pressure and ensure the safety and reliability of buildings or bridges.

[0029] Among them, one end of the steel corbel 2 is assembled on the steel column 1, and the other end is connected to the steel beam 3; when welding the steel beam 3 and the steel corbel 2, the lower flange between the steel beam 3 and the steel corbel 2 needs to be welded by the operator under the steel beam 3 through overhead welding. This welding method makes it inconvenient for the operator to operate the welding gun and has low welding efficiency. A welding structure 4 for welding the lower flange between the steel beam 3 and the steel corbel 2 is provided on the steel beam 3, which improves the welding efficiency and avoids the difficult overhead welding operation.

[0030] Among them, the welding structure 4 is a welding hole 41 and a connecting plate 42 formed on the steel beam 3, and the connecting plate 42 is assembled on the welding hole 41; wherein, the welding hole 41 is a welding hole 41 pre-designed and cut on the side plate 33 of the steel beam 3. In this embodiment, the size of the welding hole 41 is 300mm*300mm, and the welding hole 41 is opened on the steel beam 3 near one end of the steel corbel 2. The steel beam 3 includes a top plate 31, a bottom plate 32 and a side plate 33; the top plate 31 and the bottom plate 32 are connected by the side plate 33, and the welding hole 41 is opened on the side plate 33 at the connection between the side plate 33 and the bottom plate 32, ensuring that sufficient space can be provided for the welder to complete the welding work of the lower flange in a flat welding manner, thereby improving work efficiency.

[0031] Furthermore, through the welding hole 41, the welder can directly insert the welding gun into the welding place of the steel beam 3 and the steel bracket 2 to perform flat welding on the lower flange of the connection. Compared with overhead welding, flat welding not only has a better welding field of vision, but also a more stable welding process, and is easy to control the welding heat input, which significantly improves the welding quality and efficiency, and reduces weld defects.

[0032] Furthermore, after the welding of the lower flange is completed, the connecting plate 42 is assembled on the welding hole 41, and the welding hole 41 area is precisely welded and sealed to ensure that the structural strength and sealing after closure are not lower than the original structure and meet the design requirements. In addition, a welding lining strip 411 for welding the connecting plate 42 is provided on the welding hole 41, which improves the welding quality and prevents problems such as local stress concentration or water leakage.

[0033] Among them, a positioning structure 5 for connecting the steel corbel 2 is fixed on the steel beam 3, and a plurality of positioning structures 5 are provided, which are evenly arranged on the upper surface of the end of the steel beam 3. In this embodiment, the positioning structure 5 is sheet-shaped, and a positioning groove 51 is provided in the middle of the bottom of the positioning structure 5, and the two sides of the positioning groove 51 are respectively a welding part 52 and an abutting part 53. During assembly, the welding part 52 is welded to the steel beam 3 in advance, and the positioning groove 51 serves to distinguish the welding part 51 from the abutting part 52. The positioning structures 5 on both sides of the positioning groove 51 are welding parts 51 and abutting parts 52 of the same size, so that the forces acting on the steel beam 3 and the steel corbel 2 are equal, and can be more stably assembled between the steel beam 3 and the steel corbel 2; after the steel beam 3 and the steel corbel 2 are welded, the steel beam 3 is then hoisted so that the bottom of the abutting part 53 abuts against the steel corbel 2, and the positioning groove 51 is located at the joint of the steel corbel 2 and the steel beam 3. The positioning groove 51 ensures the accurate docking between the steel beam 3 and the steel corbel 2, reduces the adjustment time during the installation process, and improves the installation accuracy.

[0034] Among them, a hoisting hole 521 for hoisting the steel beam 3 is provided on the welding portion 52, which facilitates the hoisting of the steel beam 3 and improves the construction efficiency.

[0035] A welding node of a box-type steel beam not only improves the convenience and safety of welding operations by changing the welding posture, but also effectively controls welding deformation, improves the overall quality and aesthetics of the structure, shortens the construction period, and reduces costs.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
