Brief introduction of bridge slab

Bridge plate is a special thick steel plate for manufacturing bridge structural parts. It is made of special steel, carbon steel and low alloy steel for bridge construction. The end of the steel number is marked with Q (bridge).

In fact, the bridge steel plate is easy to understand. By analyzing the name of the bridge steel plate, we can understand that the bridge steel plate is an integral part of the bridge. Bridge steel plate is a special thick steel plate for manufacturing bridge structural parts. It is made of special steel, carbon steel and low alloy steel for bridge construction. The end of the steel number is marked with Q (bridge). In order to increase your understanding of bridge steel plate and enable more people to understand bridge steel plate, we will mainly summarize and explain the characteristics of bridge steel plate.

1.High strength and good toughness. The bridge slab has high strength, good toughness, acid and alkali resistance, anti-corrosion and moth proof. The static bending strength is equivalent to 4-10 times of the bending strength of wood and 4-5 times that of wood plywood. It can be sawed and nailed, greatly reducing the number of formwork support.

2. Bridge steel plate has good water resistance and low thermal conductivity

3. The bridge steel plate surface is flat and smooth. Easy demoulding, good pouring surface quality, cancelled plastering operation, reduced workload, improved work efficiency and shortened construction period.

4. Many times of use and long service life.

Carbon steel for bridge construction includes a3q for riveting bridge structure and 16q for welding bridge structure; Low alloy steels for bridge structures include 12mnq, 12mnvq, 15MnVNq, 16Mnq, etc. The thickness of bridge steel plate is 4.5 ~ 50mm. Highway and railway bridges used for making riveted and bolted welded structures, including sea crossing bridges. It is used for erecting railway bridges, highway bridges, sea crossing bridges, etc. It is required to have high strength, toughness, bear the load and impact of locomotive and vehicle, and have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. The steel for bolted welded bridge should also have good welding performance and low notch sensitivity. The surface defects of bridge steel plate are allowed to be cleaned. The cleaning depth shall not be greater than half of the steel thickness tolerance from the actual size, and the thickness shall be guaranteed. The cleaning place shall be smooth without edges and corners. This steel plate also has many advantages. Its construction is fast and simple, and there is no need to increase the section size and weight of the strengthened components. And its end anchorage is very important. If it is not handled properly, it will cause tearing off, which belongs to brittle failure. Heat resistant steel plate and other varieties are crossed with thin plate. The steel plate should also be maintained regularly in the process of use, so as to prolong its service life, because once there is a problem, it may cause an accident. The quality of the bridge steel plate produced by our factory is guaranteed. Welcome to call us for advice. We will serve you wholeheartedly.
