Light and high-strength metal bridge plate and manufacturing method thereof

Abstract

The invention discloses a light and high-strength metal bridge plate and a manufacturing method thereof. The metal bridge plate comprises the following components in parts by mass: 50 to 70 parts of an aluminium material, 10 to 20 parts of an iron material, 3 to 8 parts of a magnesium material, 3 to 8 parts of a nickel material, 0.1 to 0.3 part of a graphene material, 3 to 8 parts of feldspar powder, 1 to 2 parts of fumed silica and 0.2 to 0.4 part of aerogel. The modified composite metal bridge plate manufactured through the aluminium material, the iron material, the magnesium material, the nickel material, the graphene material, feldspar powder, fumed silica and aerogel is light in mass, high in strength and good in toughness, and has good pressure resistant, stretching resistant, antiseismic and anticollision functions; and the metal bridge plate is a porous plate, moisture can directly penetrate through the plate, the metal bridge plate has good rustproof and water-permeable functions, a lot of steel can be saved, service life is long, and economic benefits are greatly increased.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a light-weight and high-strength metal bridge plate and a manufacturing method thereof. Background technique [0002] Regardless of whether it is a cross-sea or a mountain-crossing bridge, it is now basically using concrete plus steel frame, thickened steel plate welding as support plate, and then concrete steel bar or asphalt on the steel plate, construction and material transportation costs are high, and the construction period is long. Especially for bridges, the most difficult problem to solve is the problem of water leakage and rust in the joints. Many bridges suddenly collapsed because of the vibration caused by cars passing by. When it rains or snows, water seeps into the steel bars from the joints of the bridge. And the steel plate, causing the steel and steel plate to rust. Some non-professionals one-sidedly think that it is a problem of cutting corners. In fact, ...

AI Technical Summary

Problems solved by technology

[0002] Whether it is a sea-crossing or a mountain-crossing bridge, it basically uses concrete and steel frames, welds thick steel plates to make support plates, and then makes concrete reinforcement or paves asphalt on the steel plates. The construction and material transportation costs are high and the construction period is long. In particular, the most difficult problem of bridges is the joint leaking and rusting problems. Many bridges suddenly collapsed because the cars kept passing by, causing vibrations. When it rains or snows, water seeps into the steel bars from the joints of the bridge. With the steel plate, causing the steel and the steel plate to rust
