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

Methods and characteristics of bridge steel plate reinforcement

Bridge is a kind of transportation facility. Through the reasonable application of bridge steel plate, we can also build different styles and strong bridges. However, there are many methods to strengthen bridges, and different reinforcement methods have different characteristics. Steel bonding reinforcement is one of them. The principle is to bond the bridge steel plate and concrete components, which are bonded together through epoxy adhesive, and use the tensile strength of bridge steel plate to enhance the bearing capacity of bridge components. The method of bonding steel to strengthen bridges mainly has the following characteristics.

The principle is to bond the bridge steel plate and concrete components, which are bonded together through epoxy adhesive, and use the tensile strength of bridge steel plate to enhance the bearing capacity of bridge components. The method of bonding steel to strengthen bridges mainly has the following characteristics.

1. The construction is fast, simple and basically does not increase the section size and weight of the strengthened components.

2. When the original component is in a high stress state, the unloading scheme should be adopted to eliminate the strain asynchrony of new and old materials.

3. The reinforced steel plate should be between 2 ~ 6mm. If this thickness cannot meet the design requirements, wet wrapped steel method or bonded carbon fiber method can be used.

4. The end anchorage of steel plate is very important. If it is not handled properly, it is easy to tear off, which belongs to brittle failure.

5. If the steel plate for strengthening beams and columns is thick, it is recommended to use the outsourcing steel method. This method is often used in storey addition and seismic reinforcement.

6. When the base temperature is below 5 ℃, the steel bonding method shall be supplemented by heating measures to accelerate curing.

7. The structure of the negative moment section of the frame joint is difficult to deal with, so it is suggested to use the local amplitude modulation method and paste the beam bottom as much as possible.

There are many advantages of using bonded steel to strengthen the bridge, such as firmness and durability, which can ensure the strength and stiffness of the bridge structure; Steel bonding reinforcement also has the function of rapid construction. It is clean in the construction process and now there is no wet operation; Steel bonded reinforcement is also flexible and diverse, which is very dexterous and adaptable in bridge reinforcement; Economical and reasonable, fast construction, and material saving, it is very popular in bridge reinforcement construction.

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.
