[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] A specific embodiment of this utility model discloses a steel folded beam, suitable for variable elevation buildings with a height difference of less than 2 / 3 of the beam height, such as... Figures 1-2 As shown, the structure includes a high-elevation steel beam segment 1, a low-elevation steel beam segment 2, a vertical rib assembly 3, a horizontal stiffening rib assembly 4, and a web assembly 5. The high-elevation steel beam segment 1, low-elevation steel beam segment 2, vertical rib assembly 3, and horizontal stiffening rib assembly 4 have equal cross-sections.

The thickness of the vertical rib assembly 3, the horizontal stiffening rib assembly 4, and the web assembly 5 is equal to the flange thickness of the high-elevation steel beam segment 1 and the low-elevation steel beam segment 2.

[0033] like Figure 2 As shown, the high-elevation steel beam segment 1 includes a first upper plate 11, a high-elevation web 12, and a first lower plate 13. The high-elevation web 12 connects the first upper plate 11 and the first lower plate 13 to form an "H"-shaped structure. The first upper plate 11 and the first lower plate 13 have the same length and extend horizontally along the high-elevation web 12. The low-elevation steel beam segment 2 includes a second upper plate 21, a low-elevation web 22, and a second lower plate 23. The low-elevation web 22 connects the second upper plate 21 and the second lower plate 23 to form an "H"-shaped structure. The second upper plate 21, the low-elevation web 22, and the second lower plate 23 are all connected to the vertical rib assembly 3.

[0034] like Figure 1As shown, the vertical rib assembly 3 includes a connecting vertical rib 31, an upper vertical rib 32, and a lower vertical rib 33.

The lower vertical rib 33 is connected to the first lower plate 13 and is coplanar with the upper vertical rib 32. The first upper plate 11 and the first lower plate 13 are connected to the upper vertical rib. After being connected to the lower vertical rib 32 and the lower vertical rib 33, it extends to the connecting vertical rib 31. One side of the connecting vertical rib 31 is connected to the first upper plate 11 and the first lower plate 13, and the other side is connected to the second upper plate 21, the low elevation web plate 22 and the second lower plate 23, so that both the high elevation steel beam segment 1 and the low elevation steel beam segment 2 are connected to the connecting vertical rib 31. The bottom surface of the lower vertical rib 33 is coplanar with the bottom surface of the second lower plate 23 and is connected by the horizontal stiffening rib assembly 4.

[0035] By setting the vertical rib plate assembly 3, the steel folded beam can transition from the high-elevation steel beam segment 1 to the low-elevation steel beam segment 2, thus meeting the needs of buildings with variable elevation floors.

[0036] like Figure 1 , Figures 3-4 As shown, the horizontal stiffening rib assembly 4 includes a middle horizontal rib 41, a low-elevation horizontal rib 42, a high-elevation horizontal rib 43, and a bottom horizontal rib 44. One end of the middle horizontal rib 41 is connected to the upper vertical rib 32, and the other end is connected to the connecting vertical rib 31. The middle bottom horizontal rib 44 is coplanar with the second upper plate 21. The high-elevation horizontal rib 43 is connected to the upper vertical rib 32, and the high-elevation horizontal rib 43 is coplanar with the middle horizontal rib 41. A first insertion joint 431 is provided in the middle of the high-level horizontal rib plate 43, and the high-level web plate 12 is inserted into the first insertion joint 431 to connect with the upper vertical rib plate 32; the low-level horizontal rib plate 42 is coplanar with the first lower plate 13, and a second insertion joint 421 is provided in the middle of the low-level horizontal rib plate 42, and the low-level horizontal rib plate 42 is connected with the connecting vertical rib plate 31, and the low-level web plate 22 is inserted into the second insertion joint 421 to connect with the low-level horizontal rib plate 42.

[0037] By setting up the horizontal stiffening rib assembly 4, the rigidity and stability of the structure can be improved, and the horizontal strength of the transition section between the high-elevation steel beam segment 1 and the low-elevation steel beam segment 2 can be increased, preventing weak points in the steel folded beam.

[0038] like Figure 1 , Figure 3As shown, the web assembly 5 includes a first web 51 and a second web 52. A third insertion joint 411 is provided in the middle of the middle horizontal rib 41. The first web 51 is disposed between the upper vertical rib 32 and the connecting vertical rib 31. One end of the first web 51 is connected to the first upper plate 11, and the other end passes through the third insertion joint 411 and is connected to the first lower plate 13. The second web 52 is disposed between the lower vertical rib 33 and the connecting vertical rib 31. One end of the second web 52 is connected to the first lower plate 13, and the other end is connected to the bottom horizontal rib 44.

[0039] Preferred, such as Figure 2 As shown, a high-elevation beam connection joint 131 is provided on the first lower plate 13 to facilitate the connection of the first web plate 51 and the second web plate 52 with the first lower plate 13.

[0040] By setting the web assembly 5, the stiffness and stability of the structure can be improved, and the vertical strength of the transition section between the high-elevation steel beam segment 1 and the low-elevation steel beam segment 2 can be increased, thereby improving the strength and stability of the steel folded beam.

[0041] Compared with existing technologies, the steel folded beam of this invention features a constant cross-section and variable elevation, making it suitable for buildings with varying elevations where the height difference is less than 2 / 3 of the beam height. By setting a vertical rib assembly 3, the steel folded beam can transition from a high-elevation steel beam segment 1 to a low-elevation steel beam segment 2, thus meeting the needs of buildings with varying floor levels. The horizontal stiffening rib assembly 4 enhances the structural rigidity and stability, and increases the horizontal strength of the transition section between the high-elevation and low-elevation steel beam segments 1 and 2, preventing weak points in the steel folded beam. The web assembly 5 further enhances the structural rigidity and stability, and increases the vertical strength of the transition section between the high-elevation and low-elevation steel beam segments 1 and 2, thereby improving the overall strength and stability of the steel folded beam. This invention ensures the structural strength and stability of the transition section between the high-elevation and low-elevation steel beam segments 1 and 2, and saves construction time through prefabrication, making it easy to operate and simple to manufacture.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
