Bridge steel plate is also called support steel plate, leveling steel plate, slice steel plate, etc., which is usually used for the material Q235 or Q345 steel is the common steel plate material model. Railway or highway Bridges bear the impact load of vehicles. Bridge steel plates require certain strength, toughness and fatigue resistance, and have high requirements for the surface quality of steel. Basic open hearth steel is often used in bridge steel plate, and common low alloy steel such as 16 manganese, 15 manganese alum nitrogen (YB168-70) tether welding bridge steel plate should also have good welding performance and low notch sensitivity.
1, the bridge steel plate has high strength, good toughness, its strength is equivalent to the wood template 4-10 times, equivalent to the wood bending strength 8-10 times.
2, bridge steel plate width, joint less, the specification is 2440×1220mm, equivalent to 6.6 pieces of 1500×300mm steel mold area, can reduce the number of template support square wood, improve the speed of support and disassembly, save time and material.
3, the surface of the bridge steel plate is smooth and smooth, easy to demoulding, the adsorption force is only 1/8 of the steel mold, the plastering operation can be cancelled, and the progress of the project can be accelerated.
4, bridge steel plate has a strong waterproof, anti-corrosion, moth-proof, anti-aging, water and moisture are not easy to deformation.
5, bridge steel plate has long service life, high turnover times, and can be reused double-sided.
6, bridge steel plate thermal conductivity is small, winter construction insulation is good.
7, bridge steel plate is widely used in expressways, viaducts, overpasses, DAMS, tunnels and beams and columns in the water concrete pouring, also suitable for high-rise buildings in the horizontal die plate, shear wall, vertical wall template, and all kinds of vehicles.
