[0018] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0019] This utility model provides a lightweight rigid crossbeam for railways, which can solve the problems of complex structure, heavy weight, high construction difficulty and cost in related technologies.
[0020] See Figures 1-5As shown in the figure, a lightweight rigid crossbeam for railways provided by this utility model includes: two side columns 1 with H-shaped cross-sections, a top plate 2 fixed to the top of each side column 1, and a first stiffening plate 3 between the top plate 2 and the side column 1; and a crossbeam 4 installed between the two side columns 1, the crossbeam 4 also having an H-shaped cross-section, a bottom plate 5 fixed to both ends of the crossbeam 4, and a second stiffening plate 6 between the bottom plate 5 and the crossbeam 4. The top plate 2 is fixed to the bottom plate 5 by bolts 7. By directly fixing the H-shaped steel crossbeam 4 to the side columns 1, connecting the two using the top plate 2 and the bottom plate 5, and using stiffening plates to improve the crossbeam's resistance to bending deformation and structural strength, the structure is simple, the crossbeam's self-weight is reduced, and the construction difficulty and cost are lowered.
[0021] See 2 and Figure 3 As shown, in some embodiments, the base plate 5 is fixed to the flange of the crossbeam 4. The contact area between the flange and the base plate 5 is large, which helps to disperse the local stress on the crossbeam 4 and improve the structural strength.
[0022] See 2 and Figure 3 As shown, in some embodiments, there are multiple second stiffening plates 6, some of which are symmetrically fixed to opposite sides of the web of the crossbeam 4, enhancing the load-bearing capacity, stiffness and stability of the crossbeam 4, while also serving as a connection and reinforcement function.
[0023] See 2 and Figure 3 As shown, in some embodiments, the second stiffening plate 6 is fixed on the web end face of the crossbeam 4 to improve the crossbeam 4's resistance to bending deformation and increase structural stability.
[0024] See 2 and Figure 3 As shown, in some embodiments, there are multiple first stiffening plates 3, some of which are symmetrically fixed to the outer side of the wing plate of the side column 1 to enhance the load-bearing capacity, stiffness and stability of the side column 1, and also play a role in connection and reinforcement.
[0025] As shown in Figure 4, in some embodiments, the first stiffening plate 3 is symmetrically fixed on both ends of the wing plate of the side column 1 to improve the bending deformation resistance of the side column 1 and increase the structural stability.
[0026] See 2 and Figure 3 As shown, in some embodiments, multiple bolts 7 are symmetrically arranged on both sides of the web of the crossbeam 4 and located between the two second stiffening plates 6, which improves the connection strength of the structure and ensures that the bottom plate 5 and the top plate 2 are subjected to uniform force.
[0027] Referring to Figure 5, in some embodiments, an anti-vibration pad 8 is installed between the top plate 2 and the bottom plate 5. The top plate 2 and the bottom plate 5 are connected by a fixing piece 9. The anti-vibration pad 8 can absorb the vibration of the crossbeam 4, improve the seismic resistance of the steel crossbeam, and extend its service life.
[0028] Referring to Figure 5, in some embodiments, the fixing plate 9 is L-shaped, with one end of the fixing plate 9 resting on the base plate 5 and the other end attached to the outer side of the top plate 2, the anti-vibration pad 8, and the base plate 5. The bolts 7 are respectively installed at both ends of the fixing plate 9 to ensure the connection strength of the structure.
[0029] As shown in Figure 5, in some embodiments, the top plate 2 has a U-shaped cross section, and the bolt hole of the fixing piece 9 near one end of the top plate 2 is strip-shaped. The bolt 7 can move within the strip-shaped hole, reserving space for the vibration of the crossbeam 4 and reducing damage to the rigid connection.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0031] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation.

Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.
[0032] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.
