Steel wire for bridges

　　What should be paid attention to when using steel wire strands for bridges?
　　1. In the application of bridge steel wire strands, any heating and deformation measures are prohibited to avoid reducing the mechanical properties of the bridge steel wire strands.
　　2. Welding is prohibited in the application. Because the strength of the weld is far lower than the strength of the steel itself, it is easy to break the wire at the weld during tensioning.
　　3. The steel wire strands for bridges should be cut with a toothless saw (grinding wheel). Cutting with electric welding or gas welding can easily damage the surrounding surface of the steel. The overheated end formed together will lead to a decrease in mechanical properties.
　　4. When using recycled steel bars for bridge steel wire strands, the bending radius must not be less than three times its diameter.
　　5. Steel wire strands packaged into coreless coils should be released from the inner core tap in a vertical state. The stretched steel wire strands are spring-like and straighten automatically. Direction: The spring-like spiral direction after tapping is consistent with the twisting direction of the wire strand; otherwise, the wire will be twisted or the wire will be twisted.
　　6. The twisting direction of bridge steel wire strands is generally left-handed. Right-handed twisting should be specified in the contract; otherwise, it will directly affect its connection with the anchor.
　　7. The quality of the bridge steel wire strand pier is not directly related to the quality of the steel wire itself, but excessive strength will be detrimental to the quality of the steel wire pier. Therefore, when choosing the anchoring time of the pier, it should be clarified with the manufacturer.
　　Since the products of steel wire strand manufacturers will be used in construction projects and industrial and mining enterprises, they need to have more prominent load-bearing capacity and compressive strength, so it is very important to make a better and reasonable choice. The quality assurance provided by bridge steel wire strand manufacturers will have a better performance, so people choose better quality suppliers to fully guarantee better product quality, which is more widely reflected in the use of bridge steel wire strands. These are areas worthy of our full attention.
　　Bridge steel wire strands can be divided into prestressed type and bonded type. Better choices can be made according to actual needs to ensure that the performance is more prominent in reliability and better grasped according to the actual situation. Therefore, people need to handle it from a more professional perspective. The reliability we can seek will definitely have a better performance, so it is necessary to choose reasonable bridge steel wire strands according to actual needs. Choose reputable steel wire strands to ensure better load-bearing capacity. The wear resistance, crack resistance, and seismic performance are very prominent, so reasonable choices should be made according to the actual situation.

Application of bridge steel wire strands

With the development of the economy, road expansion projects are constantly emerging. Bridge construction is an important part of this, and the application of steel wire strands is indispensable in bridge construction.

In prestressing, bridge steel wire strands can replace steel bars. Compared with steel bars, steel wire strands are more flexible and are widely used in post-tensioned prestressed structures.

　 　Prestressed steel wire strands are composed of multiple high-strength steel wires twisted together and subjected to stress relief treatment (stabilization treatment), suitable for prestressed concrete or similar purposes. The main characteristics of prestressed steel wire strands are high strength and excellent relaxation performance.

New bridge construction, repair and reinforcement of concrete structures, and reconstruction will all use such prestressed bridge steel wire strands.

　　Prestressed steel wire strands are a new type of building material used as structural reinforcement and components for various prestressed concrete projects and buildings. , Widely used in bridges, highways, railways, geotechnical engineering

Anchoring, slope protection, high-rise buildings, industrial plants, stadiums, large-scale facilities, hydropower stations, nuclear power plants, water conservancy projects, etc. Especially the application of bridge steel wire strands.

　　Currently, the usage rate of steel wire strands in global road and bridge construction projects has reached 95% while the usage rate in China has only reached 10% From the current situation, prestressed bridge steel wire strands have broad development prospects and huge application potential in China's

bridge construction engineering field.
