[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] The steel structure 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figure 1-Figure 9 As shown, the steel structure 100 according to the embodiment of the utility model comprises a weldment 1, a steel section 2 and a steel bar 3. The weldment 1 comprises a metal plate 11, the metal plate 11 having a first end 111 and a second end 112 opposite to each other in a first preset direction, and the first preset direction is one of the thickness direction, the width direction and the length direction of the metal plate 11.

[0029] The first end portion 111 is provided with a threaded hole 13 , and the second end portion 112 is provided with a groove 14 .

[0030] Alternatively, the first end 111 is provided with a mounting hole 113, and the weldment 1 further comprises a sleeve 12, at least a portion of the sleeve 12 is disposed in the mounting hole 113, and the sleeve 12 has a threaded hole 13. The second end 112 and the sleeve 12 are provided with a groove 14.

[0031] The weldment 1 is connected to the steel section 2 via a weld 4, and at least a portion of the weld 4 is filled in the groove 14 of the weldment 1. A portion of the steel bar 3 is threadedly engaged in the threaded hole 13.

[0032] According to the welding piece 1 of the embodiment of the utility model, by providing a threaded hole 13 on the metal plate 11 or providing a sleeve 12 with a threaded hole 13 on the metal plate 11, the welding of the sleeve and the steel section is converted into the welding of the metal plate 11 and the steel section 2. Thus, the welding condition of a single-sided groove straight weld is formed, so that the metal plate 11 and the steel section 2 can be welded together by flat welding operation, which is conducive to improving the welding quality.

[0033] Moreover, after the steel section 2 is vertically arranged and the weldment 1 is placed on the welding pad 200, the groove 14 has an opening that opens upward, so that it is convenient to weld the weldment 1. Therefore, the steel section 2 and the weldment 1 can be welded in a factory or on site, so as to improve the flexibility of the welding operation.

[0034] Therefore, by using the welding member 1 according to the embodiment of the utility model, the welding quality can be improved, the welding difficulty can be reduced, and the flexibility of the welding operation can be improved. Accordingly, the steel structure member 100 according to the embodiment of the utility model has the advantages of stable structure and low manufacturing difficulty.

[0035] like Figure 1-Figure 9 As shown, the steel structure 100 according to the embodiment of the utility model includes a welded part 1, a steel section 2 and a reinforcing bar 3, and the steel section 2 can be used as a steel frame.

[0036] In one embodiment of the present invention, Figure 1-Figure 4 As shown, the weldment 1 includes a metal plate 11 and a sleeve 12. The metal plate 11 may be a rectangular parallelepiped, and the metal plate 11 may be a steel plate. The metal plate 11 has a first end 111 and a second end 112 that are opposite to each other in a first preset direction, and the first preset direction is one of the thickness direction, the width direction, and the length direction of the metal plate 11. The first end 111 is provided with a mounting hole 113, and at least a portion of the sleeve 12 is provided in the mounting hole 113, and the sleeve 12 has a threaded hole 13. The second end 112 and the sleeve 12 are provided with a groove 14.

[0037] Optionally, the sleeve 12 is connected to the metal plate 11 by spot welding. Thus, when the weldment 1 and the steel section 2 are welded, the sleeve 12 can be kept stable, so as to improve the welding quality, reduce the welding difficulty, and weld the metal plate 11 and the sleeve 12 to the steel section 2 more stably. For example, the sleeve 12 is connected to the wall surface of the mounting hole 113 by spot welding.

[0038] like Figure 1-Figure 4As shown, the metal plate 11 has a first end face 114 and a second end face 115 opposite to each other in a first preset direction, and the metal plate 11 has a third end face 116 and a fourth end face 117 opposite to each other in a second preset direction, and the second preset direction is perpendicular to the first preset direction. The first end face 114 is provided with a mounting hole 113, and a portion of the second end face 115, a portion of the third end face 116 and a portion of the sleeve 12 are cut off to form a groove 14. This can make the structure of the weldment 1 more reasonable.

[0039] For example, the first preset direction may be a left-right direction, and the second preset direction may be an up-down direction. Figure 5 As shown by the arrow E in the figure, the up and down directions are as shown in 1 and Figure 5 As shown by arrow F in FIG.

[0040] The first end face 114 is the right end face, the second end face 115 is the left end face, the third end face 116 is the upper end face, and the fourth end face 117 is the lower end face. The upper left corner of the metal plate 11 is cut off, and the upper left part of the sleeve 12 is cut off to form a groove 14. The weldment 1 and the steel section 2 can adopt a full penetration T-joint and fillet joint combination weld.

[0041] like Figure 3 and Figure 4 As shown, the first end face 114 is provided with a plurality of mounting holes 113, and the plurality of mounting holes 113 are arranged at intervals along the length direction of the metal plate 11. There are a plurality of sleeves 12, and the plurality of sleeves 12 are arranged in a one-to-one correspondence in the plurality of mounting holes 113. The steel structure 100 may include a plurality of steel bars 3, and the plurality of steel bars 3 may be threadedly matched with the threaded holes 13 of the plurality of sleeves 12 in a one-to-one correspondence, that is, a portion of each steel bar 3 is threadedly matched in the threaded hole 13. In this way, the plurality of steel bars 3 can be connected to the section steel 2.

[0042] like Figure 5-Figure 8 As shown, in another embodiment of the utility model, the weldment 1 includes a metal plate 11, which may be a rectangular parallelepiped, and may be a steel plate. The metal plate 11 has a first end 111 and a second end 112 opposite to each other in a first preset direction, and the first preset direction is one of the thickness direction, the width direction, and the length direction of the metal plate 11. The first end 111 is provided with a threaded hole 13, and the second end 112 is provided with a groove 14.

[0043] Optionally, the first end face 114 is provided with a threaded hole 13, and a portion of the second end face 115 and a portion of the third end face 116 are cut off to form a groove 14. This can make the structure of the weldment 1 simpler. For example, the upper left corner of the metal plate 11 is cut off to form the groove 14.

[0044] like Figure 7 and Figure 8As shown, the first end surface 114 is provided with a plurality of threaded holes 13, and the plurality of threaded holes 13 are arranged at intervals along the length direction of the metal plate 11. The steel structure 100 may include a plurality of steel bars 3, and the plurality of steel bars 3 may be threadedly matched with the plurality of threaded holes 13 in a one-to-one correspondence, that is, a portion of each steel bar 3 is threadedly matched in the threaded hole 13. In this way, the plurality of steel bars 3 may be connected to the section steel 2.

[0045] Optionally, the ratio of the size of the remaining part of the second end face 115 in the second preset direction to the size of the first end 111 in the second preset direction is less than or equal to a preset value. In other words, most of the second end face 115 is cut off. This can increase the depth of the groove 14, thereby further improving the welding quality. For example, the ratio of the size of the remaining part of the second end face 115 in the second preset direction to the size of the first end 111 in the second preset direction is less than or equal to 1 / 30.

[0046] Optionally, the first preset direction is one of the thickness direction and the width direction of the metal plate 11, and the second preset direction is the other of the thickness direction and the width direction of the metal plate 11. The groove 14 extends along the length direction (e.g., the front-to-back direction) of the metal plate 11. This can make the structure of the weldment 1 more reasonable. Figure 4 and Figure 8 As shown by arrow G in FIG.

[0047] The slope 141 of the groove 14 is a rectangular plane. This can make the structure of the weldment 1 more reasonable. The angle between the slope 141 of the groove 14 and the first preset direction is greater than or equal to 50 degrees and less than or equal to 70 degrees. This can further improve the welding quality and reduce the welding difficulty. For example, the welding surface 21 of the steel section 2 is vertically arranged, and the angle between the slope 141 of the groove 14 and the welding surface 21 of the steel section 2 is greater than or equal to 20 degrees and less than or equal to 40 degrees.

[0048] When welding the weldment 1 and the steel 2, the groove 14 can form a V-shaped opening between the weldment 1 and the steel 2. This forms a welding condition for a single-sided groove straight weld, which can be operated flat, and is conducive to improving welding quality.

[0049] like Figure 1 and Figure 5 As shown, the steel section 2 is arranged vertically, the opening of the groove 14 faces upward, and the groove 14 extends in the horizontal direction. The groove 14 with the opening facing upward is convenient for welding, that is, the steel section 2 and the weldment 1 can be welded in the factory or on site, so as to improve the flexibility of the welding operation. The opening of the groove 14 faces upward, and when performing flat welding operation, the molten welding wire can easily fill the groove 14, which helps to improve the welding quality.

[0050] The utility model also provides a building 1000. Fig. 9 As shown, the building 1000 according to the embodiment of the utility model comprises a steel-concrete column 300, a reinforced concrete beam 400 and a weldment 1.
