[0002] Bridges are key infrastructure connecting different regions and cities, and their design and materials have undergone significant changes over the past few centuries. Although traditional reinforced concrete bridges have good load-bearing capacity.

[0003] However, the mechanical strength of current steel plate composite bridges may decrease to some extent after long-term use, which will reduce their safety performance. At the same time, although existing anti-corrosion coatings can reduce corrosion, their effectiveness is still insufficient in highly corrosive environments. Therefore, it is necessary to design a new type of reinforced steel plate composite beam for bridges. Utility Model Content

[0014] By adopting the above technical solution and applying a waterproof coating, waterproofing can be achieved.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, by setting up a first reinforcing plate, a second reinforcing plate, a first fastening nail, and a second fastening nail, before installation, the first reinforcing plate and the second reinforcing plate can be respectively attached close to the outer surface of the I-beam, and the first fastening nail and the second fastening nail can be tightened with tools to fix the first reinforcing plate and the second reinforcing plate. By setting up the first reinforcing plate and the second reinforcing plate, the mechanical strength of the I-beam can be improved and the service life of the I-beam can be extended.

The primer seals the surface and prevents contact between the metal and moisture or air, thus reducing the risk of corrosion. The anti-corrosion coating forms a protective film, effectively resisting environmental damage. The intermediate coating not only strengthens the overall structure but also provides additional adhesion and protection for the final topcoat. This layer helps absorb impact and friction. The topcoat protects the underlying coatings and provides aesthetic appeal; it also increases wear resistance and protects against UV rays, chemical corrosion, and other environmental influences.

The third fastening nail 8 is then tightened using tools to install the rain shield 7. The rain shield 7 effectively blocks rainwater. The primer 9 improves the adhesion of subsequent coatings and provides optimal coverage and uniformity. It seals the surface and prevents... When metal comes into contact with moisture or air, the risk of corrosion is reduced. The anti-corrosion coating 10 forms a protective film that effectively resists environmental damage. The intermediate coating 11 not only enhances the overall structure but also provides additional adhesion and protection for the final topcoat 12. This layer helps absorb impact and friction.
