Q: the role of steel strand?
Answer: Steel strands are used to produce prestressed concrete. Generally, prefabricated beams and prefabricated slabs for bridges are also used in some construction projects. Steel strands are usually used in combination with prestressed clips and prestressed anchors. Steel strands are usually used for load-bearing cables, cables, reinforced cores, etc.
Q: the use of steel strand pay attention to matters?
Answer: 1. Any form of heating and deformation measures is strictly prohibited in the use of prestressed steel, so as not to reduce the mechanical properties of prestressed steel. 2. Welding is strictly prohibited in use, because the strength of the welding spot is much lower than that of the steel itself, which is easy to cause wire breakage at the welding spot during tensioning. 3. The cutting of prestressed steel should use no tooth data (grinding wheel card). The use of electric and gas welding cutting is easy to damage the surface around the steel. At the same time, the end of the local heating, so that the performance is significantly reduced. 4. The steel strand packaged in a coil without shaft shall be paid off from the inner ring in a vertical state, and the steel strand after being drawn out shall be spring-shaped and straightened automatically. Tap direction: the spiral direction of the spring shape after the tap is consistent with the twist direction of the stranded wire, otherwise it will be twisted or twisted. 5. The twist direction of the steel strand is generally left twist, and right twist should be indicated in the contract, otherwise it will directly affect the coordination with the anchorage. 6. The quality of prestressed steel wire head is not directly related to the quality of the steel wire itself, but too high strength will not be conducive to the quality of the steel wire head. Therefore, when you choose the head anchor, you should explain it to our company in the order.
Q: the classification of steel strand?
Answer: The most commonly used steel strands are galvanized steel strands and Prestressed concrete strands. The diameter of commonly used Prestressed concrete strands is in the range of 9.53 mm-17.8mm, with a small number of thicker steel strands. The steel wires in each Prestressed concrete strand are generally 7, and there are also 2, 3 and 19 wires. The steel wires can have metal or non-metal anti-corrosion layers.
q: steel strand production methods?
Answer: The manufacturing process is divided into monofilament manufacturing and stranded wire manufacturing. When making monofilament, (cold) wire drawing technology is adopted. According to the different materials of the product, it can be high carbon steel wire rod, stainless steel wire rod or medium and low carbon steel wire rod. If galvanizing is required, electroplating or hot-dip plating should be carried out on monofilament. In the process of strand manufacturing, multiple steel wires are twisted into products by stranding machine. The Prestressed concrete strand needs to be continuously stabilized after forming. The final product is generally collected on the I-wheel or completed by shaftless roll.
Q: What are the application areas of steel strand?
Answer: The use strength of steel strand is very high, and the working performance is top grade. In our lives, its main nature is fixed buildings, so the use of steel strands is very wide, because many things in our lives need to be fixed. Steel strands are mainly used in some construction sites, bridge nets, road guardrails. Like many dangerous areas, steel strands are used to isolate people from danger, especially many children. There is also the use of steel strands in the protective net of the bridge, which can not only prevent people from doing stupid things on the bridge, but also prevent the vehicle from falling off the bridge in the event of a traffic accident.
Q: What is the difference between bonded and unbonded steel strands?
Answer: Steel strands can also be divided into bonded steel strands and unbonded steel strands. The difference between bonded and unbonded steel strands is whether the steel strands themselves will be in contact with concrete during construction, which is also due to the different production methods of the two.
