Hello everyone, today is a special day. So where is the special? That is we do not want to work! Haha! We just returned from the National Day. Whether do you feel very tired when working today? I just saw a piece of newspaper. This year during the National Day, the number of visitors reached 700 million people! That is really a staggering figure. The highways in some places like Guangdong were jammed. After this trip, it is estimated that there will be a lot of bridges and roads needing to be maintained. We often hear the term "prestressed carbon fiber board" in road maintenance. Let's talk about it today. What kind of role does the prestressed carbon fiber board play in the road and bridge maintenance?
Prestressed carbon fiber board is a common reinforcement system, suitable for small cross section or reinforcement of reinforced concrete bending, tension and large eccentric compression components. So what is the prestressing force? The prestressing force is to add the pulling force in the components in advance so that the prestressed tension is subjected to tensile stress, which causes a certain deformation to cope with the load on the steel structure itself. What are the benefits of this prestressed carbon fiber board reinforcement?
First, good crack resistance, stiffness. Due to the prestressing of the component, the occurrence of the crack is greatly delayed. Under the action of the load, the component does not have any cracks or the crack is delayed. Therefore, the rigidity of the component is increased and the durability of the structure is increased too.
Second, the vertical shear and main tensile stresses of concrete beams can be reduced. The prestressed beam of prestressed concrete beam can reduce the vertical shear force near the bearing in the beam. And because of the existence of prestressing froce in the concrete section, the main tensile stress under the load is reduced.
Third, to improve the fatigue resistance of components. Because of the steel bars with strong prestressing force, the magnitude of the stress change is relatively small during the use phase due to the loading or unloading. So it can improve the fatigue strength, which is advantageous for the structure subjected to the dynamic load.
Mankate prestressed carbon fiber board uses Japan T800 imported carbon fiber silk. It has 50 years anti-aging effect and high strength. The quality is only 1/5 of the steel. It has good acid corrosion resistance and it doesn’t need regular maintenance! Mankate prestressed carbon fiber board is so excellent.
