[0076] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings.

[0080] According to an embodiment of the present invention, a steel structure is provided. Figures 1 to 3 The steel structure includes a column assembly 1 and a crossbeam 5. The column assembly 1 includes a column 10 and a corbel 20. The steel structure has a vertical direction Z and a transverse direction, where the transverse direction can be any direction perpendicular to the vertical direction Z. The column 10 extends vertically and has a certain height. It can be installed on the ground, underground, or on a load-bearing member. The corbel 20 is fixedly mounted on the column 10 and is used to connect to the crossbeam 5.

[0081] The column 10 is provided with a first through-hole 122 and a second through-hole 128. The first through-hole 122 is provided to pass through the column 10 transversely along a first direction X. The second through-hole 128 is provided to pass through the column 10 transversely along a second direction Y. The first and second directions are provided in different directions.

[0082] The corbel 20 may include rectangular connecting tubes. Each rectangular connecting tube has a rectangular cross-section. The rectangular connecting tubes include a first rectangular connecting tube 22 and a second rectangular connecting tube 24. The first rectangular connecting tube 22 extends along a first direction through the first through-hole 122. The second rectangular connecting tube 24 extends along a second direction through the second through-hole 128.

[0083] The first rectangular connecting tube 22 and the second rectangular connecting tube 24 are fixedly arranged crosswise. The corbel 20 is fixedly connected to the column 10. More preferably, the first rectangular connecting tube 22 and the second rectangular connecting tube 24 can be arranged in a crosswise manner to meet the structural layout requirements of the steel structure. It will be understood that by arranging the first direction and the second direction perpendicular to each other, the first rectangular connecting tube 22 and the second rectangular connecting tube 24 can be arranged in a crosswise manner.

[0084] The crossbeam 5 is a rectangular tube extending in the transverse direction and is laterally butted against the rectangular connecting tubes 22 and 24 and fixed by welding.

[0085] With this arrangement, the first and second rectangular connecting tubes 22 and 24 of the corbel 20 are cross-fixed and extend through the first and second through-holes 122 and 128 of the column 10, respectively, to be fixedly connected to the column 10. This one-piece column 10 structure is fixedly connected to the crossbeam 5, forming a structurally stable and reliably connected steel structure. This steel structure is easy to assemble and highly efficient. The steel structure's compact, prefabricated components facilitate transportation.

[0086] In this embodiment, please refer to Figure 3 and Figure 4 The first rectangular connecting tube 22 may be provided with a first groove 222 and a first limiting wall 224 located at the bottom of the first groove 222 .

[0087] The second rectangular connecting tube 24 may be provided with a second groove 242 and a second limiting wall 244 located at the bottom of the second groove 242 .

[0088] The first limiting wall 224 and the second groove 242 can be arranged in a complementary manner. The first limiting wall 224 is limited in the second groove 242.

[0089] The second limiting wall 244 and the first groove 222 are complementary in structure, and the second limiting wall 244 is limited in the first groove 222. The first rectangular connecting tube 22 and the second rectangular connecting tube 24 are fixed by welding.

[0090] With this arrangement, the first rectangular connecting tube 22 and the second rectangular connecting tube 24 of the corbel 20 can be pre-positioned by the snap-fit ​​structure, which facilitates welding and fixation between the first rectangular connecting tube 22 and the second rectangular connecting tube 24. The structure is stable, the connection is reliable, the assembly is convenient, and the assembly efficiency is high.

[0091] It is understood that, to facilitate production and assembly, the first rectangular connecting tube 22 and the second rectangular connecting tube 24 can be configured with the same structure. The first groove 222 and the first limiting wall 224 of the first rectangular connecting tube 22 can be configured with the same vertical length. Correspondingly, given the identical structure of the first rectangular connecting tube 22 and the second rectangular connecting tube 24, the second groove 242 and the second limiting wall 244 of the second rectangular connecting tube 24 are also configured with the same vertical length.

[0092] With this arrangement, the first rectangular connecting tube 22 and the second rectangular connecting tube 24 can have the same structure and size, which facilitates manufacturing.

[0093] See also Figure 5 and Figure 6 In order to facilitate the assembly connection between the column 10 and the corbel 20, the column 10 can be set as a rectangular tube. The cross section of the column 10 is a ring-shaped rectangular structure.

[0094] To form a rectangular tubular column 10, the column 10 may specifically include a pair of U-shaped members 12, each having a U-shaped cross-section. The pair of U-shaped members 12 are both vertically extending. The U-shaped member 12 may specifically include a center wall 121 and a pair of side walls 125. The pair of side walls 125 are located on either side of the bottom. A first through hole 123 is provided in the center wall 121 of the U-shaped member 12. U-shaped grooves 126 are provided in the side walls 125 of the U-shaped member 12, located at the ends of the side walls 125 facing away from the center wall 121.

[0095] The side walls 125 of a pair of U-shaped parts 12 are butt-jointed and welded to form a rectangular tube column 10 , the first through holes 123 on the pair of U-shaped parts 12 are aligned to form a first through hole 122 , and the U-shaped grooves 126 on the side walls 125 of the pair of U-shaped parts 12 are jointly enclosed to form a second through hole 128 .

[0096] It is understandable that when the side walls 125 of a pair of U-shaped members 12 are butt-jointed and welded together, the U-shaped grooves 126 on the side walls 125 of the pair of U-shaped members 12 will jointly enclose a pair of aligned second through holes, thereby ultimately forming a second through hole 128 .

[0097] To facilitate welding and fixing of the rectangular connecting tubes 22 and 24 to the crossbeam 5, the ends of the rectangular connecting tubes 22 and 24 can be laterally protruding outward and provided with a first bushing 28 overlapping the inner wall of the crossbeam 5, and / or the ends of the crossbeam 5 can be laterally protruding outward and provided with a second bushing 54 overlapping the inner wall of the rectangular connecting tubes 22 and 24.

[0098] In this embodiment, please refer to Figure 2 and Figure 3 The cross sections of the first rectangular connecting tube 22 and the second rectangular connecting tube 24 are both rectangular structures. The ends of the first rectangular connecting tube 22 are both provided with first bushings 28 .

[0099] The structure of the first bushing 28 can be configured to be suitable for supporting the crossbeam 5. Part of the first bushing 28 is fixedly connected to the inner wall of the rectangular connecting tube, and part of it protrudes to the outside of the rectangular connecting tube.

[0100] The end surface of the rectangular connecting tube can be configured as a first inclined surface 26. The vertical upper end of the first inclined surface 26 of the rectangular connecting tube is positioned closer to the column 10 than the vertical lower end. A first bushing 28 partially protrudes to one lateral side of the upper end of the first inclined surface 26. The first rectangular connecting tube 22 is welded to the second rectangular connecting tube 24. This allows a portion of the first bushing 28 to be exposed outside of one lateral side of the rectangular connecting tube, thereby supporting the crossbeam 5.

[0101] See also Figure 9 Correspondingly, the crossbeam 5 can be configured as a rectangular tube. The end surface of the crossbeam 5 is configured as a second inclined surface 52. The inner wall of the upper end of the crossbeam 5 overlaps with the first bushing 28.

[0102] A second bushing 54 can be provided at the end of the crossbeam 5. Part of the second bushing 54 is fixedly attached to the inner wall of the crossbeam 5, while part of it protrudes laterally from the lower end of the crossbeam 5. The second bushing 54 overlaps the inner wall of the lower end of the rectangular connecting tube. This allows a portion of the second bushing 54 to be exposed outside the lateral side of the crossbeam 5, allowing the rectangular connecting tube to support the crossbeam 5 by supporting the second bushing 54.

[0103] See also Figure 1 The second inclined surface 52 of the cross beam 5 is butted against the first inclined surface 26 of the rectangular connecting tube and fixed by welding.

[0104] It can be understood that by providing a bushing on the inner wall of the rectangular connecting tube or the inner wall of the crossbeam 5, impurities generated by welding can be effectively prevented from entering the interior of the steel structure.

[0105] In this arrangement, the vertical upper end of the first inclined surface 26 on the rectangular connecting tube is arranged closer to the column 10 than the vertical lower end, which is convenient for lifting the beam 5 from top to bottom, and convenient for the second inclined surface 52 of the beam 5 to connect with the first inclined surface 26 of the rectangular connecting tube, so that the corbel 20 can reliably and stably support the beam 5.

[0106] The inner wall of the upper end of the crossbeam 5 overlaps with the first bushing 28 on the first rectangular connecting tube 22 and the second rectangular connecting tube 24, and the second bushing 54 of the crossbeam 5 overlaps with the inner wall of the lower end of the first rectangular connecting tube 22 and the second rectangular connecting tube 24, thereby realizing pre-positioning between the crossbeam 5 and the first rectangular connecting tube 22 and the second rectangular connecting tube 24, and facilitating welding and fixing between the second inclined surface 52 of the crossbeam 5 and the first inclined surface 26 of the rectangular connecting tube. The steel structure has a stable structure, reliable connection, convenient assembly and high assembly efficiency.

[0107] The structure of the bushing is configured to be suitable for being fixedly connected to the inner wall of the rectangular connecting tube or the inner wall of the crossbeam 5 and being able to extend to the outside of the inner wall of the rectangular connecting tube or the crossbeam 5 .

[0108] For an optional example, see Figure 7 The first bushing 28 can be configured as a U-shape. The second bushing 54 can be configured as a U-shape. The first bushing 28 and the second bushing 54 can be spaced apart.

[0109] Of course, in some other embodiments, the first bushing 28 and the second bushing 54 may be connected to each other to form an annular structure.

[0110] For an alternative example, see Figure 8 The first bushing 28 can be configured as a closed rectangular structure. The second bushing 54 can be configured as a closed rectangular structure. The first bushing 28 and the second bushing 54 can be spaced apart.

[0111] Of course, in some other embodiments, the first bushing 28 and the second bushing 54 are butted against each other to form an integral annular structure.

[0112] In a specific embodiment, an assembly method of a steel structure is described below by way of example.

[0113] See also Figures 1 to 9 First, the first limiting wall 224 of the first rectangular connecting tube 22 is positioned within the second groove 242 of the second rectangular connecting tube 24, and the second limiting wall 244 of the second rectangular connecting tube 24 is positioned within the first groove 222 of the first rectangular connecting tube 22, thereby pre-positioning the first and second rectangular connecting tubes 22, 24 of the corbel 20 via the snap-fit ​​structure. The first and second rectangular connecting tubes 22, 24 are then welded and secured.

[0114] One end of the first rectangular connecting tube 22 is then inserted through the first through-hole 123 of a U-shaped member 12. One U-shaped member 12 is then butted against the other and welded to form a rectangular tube column 10. The first through-holes 123 on the pair of U-shaped members 12 are aligned to form a first through-hole 122. The U-shaped grooves 126 on the sidewalls 125 of the pair of U-shaped members 12 together enclose a second through-hole 128. The first and second rectangular connecting tubes 22 and 24 are then welded to the column 10, respectively, to form the column assembly 1.

[0115] Then, the inner wall of the upper end of the crossbeam 5 is abutted against the first bushing 28, and the second bushing 54 is overlapped with the inner wall of the lower end of the rectangular connecting tube. After that, the second inclined surface 52 of the crossbeam 5 is docked with the first inclined surface 26 of the rectangular connecting tube and fixed by welding to form a steel structure.

[0116] In addition, the plurality of corbels 20 in this embodiment can be vertically spaced apart along the column 10. One end of the crossbeam 5 is fixedly connected to the rectangular connecting tube 22, 24 of one column assembly 1, and the other end is fixedly connected to the rectangular connecting tube 22, 24 of another column assembly 1.

[0117] Of course, in some other embodiments, at least one of the columns, the first rectangular connecting tube 22 , the second rectangular connecting tube 24 , and the crossbeam 5 may be configured as a solid steel structure or other annular structures.

[0118] In this utility model, the first and second rectangular connecting tubes of the corbel are cross-fixed and extend through the first and second through-holes of the column, respectively, to be fixedly connected to the column. This one-piece column structure can be fixedly connected to the crossbeam 5, thereby forming a stable and accurate steel structure with reliable connection and high strength. The steel structure is easy to assemble and has high assembly efficiency. The steel structure's components are compact and prefabricated, making it easy to transport.

[0119] The first rectangular connecting tube and the second rectangular connecting tube of the corbel can be pre-positioned by a snap-fit ​​structure, which facilitates welding and fixation between the first rectangular connecting tube and the second rectangular connecting tube. The structure is stable, the connection is reliable, the strength is high, the assembly is convenient, and the assembly efficiency is high.

[0120] The structures and dimensions of the first rectangular connecting tube and the second rectangular connecting tube can be identical, which facilitates manufacturing.

[0121] The end of the rectangular connecting tube can protrude laterally outward to set a first bushing, and the first bushing overlaps the inner wall of the beam, which can achieve pre-positioning between the beam and the rectangular connecting tube, and facilitate welding and fixation between the beam and the rectangular connecting tube. The steel structure has a stable structure, reliable connection, high strength, easy assembly and high efficiency.

[0122] The end of the beam can be provided with a second bushing that protrudes laterally outward, and the second bushing overlaps the inner wall of the rectangular connecting tube, which can realize pre-positioning between the beam and the rectangular connecting tube, and facilitates welding and fixation between the beam and the rectangular connecting tube. The steel structure has a stable structure, reliable connection, high strength, easy assembly and high efficiency.

[0123] The end face of the rectangular connecting tube can be set as a first inclined surface, which is convenient for lifting the crossbeam so that the second inclined surface of the crossbeam is connected to the first inclined surface of the rectangular connecting tube, so that the corbel can reliably and stably support the crossbeam, and facilitate the welding and fixation between the crossbeam and the rectangular connecting tube. The steel structure has a stable structure, reliable connection, high strength, easy assembly and high efficiency.
