Description

Technical Field

[0001] This utility model relates to the field of steel box girder technology, specifically to a corrosion-resistant steel box girder thickened plate. Background Technology

[0002] As a crucial structural component in bridges and buildings, steel box girders are frequently subjected to harsh environmental corrosion, such as moisture and acidic / alkaline media, leading to a shortened service life and reduced safety. Traditional thickened steel box girder plates suffer from poor corrosion resistance, insufficient structural strength, and excessive weight, making it difficult to meet the high-performance requirements of modern engineering projects.

[0003] Therefore, a new type of thickened steel box girder with corrosion resistance is needed to improve its corrosion resistance and structural strength while reducing its weight. Utility Model Content

[0008] As a further embodiment of this utility model: the composite plate includes a steel plate, a corrosion-resistant plate is provided on the steel plate, and an anti-slip groove is provided on the surface of the steel plate. The corrosion-resistant plate covers the surface of the steel plate and the two are attached and fixed together. There are multiple anti-slip grooves, which are evenly distributed on the surface of the corrosion-resistant plate.

The reinforcement beam is a steel beam and has a hollow groove inside. A weight-reducing groove is provided at each of the upper and lower ends of the inner side wall of the hollow groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting corrosion-resistant plates, the corrosion resistance of the steel box girder is effectively improved, and its service life is extended. Furthermore, by setting up combined mechanisms and auxiliary reinforcement mechanisms, the structural strength of the steel box girder is enhanced, enabling it to withstand greater loads.

[0013] 2.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1-4 In this embodiment of the utility model, a corrosion-resistant steel box girder thickening plate includes a composite plate body 1, a combination mechanism 2, and an auxiliary reinforcement mechanism 3.

[0023] The composite plate 1 includes a steel plate 11, on which a corrosion-resistant plate 12 is provided. Anti-slip grooves 13 are provided on the surface of the steel plate 11. The corrosion-resistant plate 12 covers the surface of the steel plate 11 and the two are attached and fixed together. There are multiple anti-slip grooves 13, which are evenly distributed on the surface of the corrosion-resistant plate 12. The overall installation of the corrosion-resistant plate 12 effectively improves the corrosion resistance of the steel box girder and extends its service life. In addition, by setting anti-slip grooves 13 on the surface of the steel plate 11, the friction of the surface of the composite plate 1 is increased, thereby improving the safety of use.

[0024] The combined mechanism 2 includes a combined frame 21 and a reinforcing frame 24. The combined frame 21 is fixedly connected to the center of the bottom end of the steel plate 11, and a groove 22 is formed at the center of the bottom end of the combined frame 21. A combination groove 23 is formed inside the groove 22, and multiple combination grooves 23 are evenly distributed on the inner sidewalls around the groove 22. The reinforcing frame 24 is fixedly connected to the outer perimeter of the bottom end of the steel plate 11, and connecting frame strips 25 are fixedly connected between the inner sidewalls of the four corners of the reinforcing frame 24 and the outer sidewalls of the four corners of the combined frame 21. By setting up the combined mechanism 2 and the auxiliary reinforcing mechanism 3, the structural strength of the steel box girder is enhanced, enabling it to withstand greater loads.

[0025] The auxiliary reinforcement mechanism 3 includes an annular reinforcement ring 31, which is fixedly connected to the center of the inner top wall of the groove 22. A reinforcement beam 32 is provided on the outer side of the annular reinforcement ring 31, and the end of the reinforcement beam 32 away from the annular reinforcement ring 31 is fixedly connected to the inner side wall of the corresponding side of the groove 22. The reinforcement beam 32 is a steel beam and has a hollow groove 33 inside. A weight-reducing groove 34 is provided at both the upper and lower ends of the inner side wall of the hollow groove 33. The hollow groove 33 and the weight-reducing groove 34 inside the reinforcement beam 32 reduce the weight of the steel box girder, thereby reducing production costs and installation difficulty.

[0026] In implementation, the corrosion-resistant plate 12 is first attached and fixed to the surface of the steel plate 11 to form a composite plate 1. Then, the combination frame 21 is fixedly connected to the center of the bottom end of the steel plate 11, and the reinforcing frame 24 is fixedly connected to the outer periphery of the bottom end of the steel plate 11. The reinforcing frame 24 and the combination frame 21 are connected by the connecting frame strip 25 to form a combination mechanism 2. Finally, the annular reinforcing ring 31 is fixedly connected to the center of the top wall of the groove 22. One end of the reinforcing beam 32 is fixedly connected to the annular reinforcing ring 31, and the other end is fixedly connected to the inner side wall of the corresponding side of the groove 22 to form an auxiliary reinforcing mechanism 3. When multiple corrosion-resistant steel box girder thickened plates are assembled and used, they can be aligned horizontally. At this time, their bottom combination grooves 23 are aligned, and connecting components can be arranged to facilitate the combination and installation between two corrosion-resistant steel box girder thickened plates, which is relatively convenient.

[0027] The working principle of this utility model is as follows: During use, the corrosion-resistant plate 12 in the composite plate 1 can effectively resist the erosion of the external environment, protect the steel plate 11 from damage, and extend the service life of the steel box girder. The anti-slip groove 13 increases the friction of the surface of the composite plate 1, improving the safety of use. The combination frame 21 and the reinforcing frame 24 in the combination mechanism 2 are connected to each other through the connecting frame strip 25 to form a stable frame structure, which enhances the overall strength of the steel box girder. The combination groove 23 is used for combination and connection with other components, which facilitates the installation and use of the steel box girder. The annular reinforcing ring 31 and the reinforcing beam 32 in the auxiliary reinforcing mechanism 3 further improve the structural strength of the steel box girder, enabling the steel box girder to withstand greater loads. The hollow groove 33 and the weight-reducing groove 34 reduce the weight of the reinforcing beam 32, thereby reducing the weight of the entire steel box girder, reducing production costs and installation difficulty.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
