How did the prestressed carbon plate come from? This should start from the reinforcement method.

Before the prestressed carbon plate reinforcement, we have many reinforcement methods, such as planting reinforcement, carbon fiber reinforcement, bonding steel reinforcement and increasing section reinforcement. These reinforcement methods have one thing in common, that is, they are passive reinforcement.

What does passive reinforcement mean?

That is, the reinforcement material officially begins to bear the force after it is officially completed. That is to say, the stress and strain of the reinforced material lag behind the stress and strain of the reinforced structure from beginning to end, so that the reinforced material begins to be stressed or only very little when the reinforced structure reaches the failure state. The disadvantage of this reinforcement method is that when carbon fiber reinforcement is not fully utilized, a large part of it will be wasted.

In order to reduce these wastes and problems caused by passive reinforcement, a new reinforcement method was born, that is, prestressed carbon plate reinforcement. How is this active reinforcement technology reinforced?

Prestressed carbon plate reinforcement

The prestressed carbon plate reinforcement is to apply prestressing by the anchors at both ends of the carbon fiber plate, so that the carbon plate and the carbon plate glue are pasted and fixed on the structure. If the adhesion of the structural adhesive will deteriorate over time, the anchor can also provide prestress at this time, and its strength is here. Speaking of the powerful, prestressed reinforcement has more than this advantage. The prestressed carbon fiber board used for prestressing also has many advantages over other reinforcement materials.

Advantages of Prestressed Carbon Fiber plates

1. Reinforced with prestressed carbon fiber board, carbon board glue will be used, which has "bonded" reinforcement, and at the same time, there are anchors, which have "non-bonded" reinforcement.

2. The prestressed carbon plate has a short construction period, high efficiency, saves time and has little impact on traffic.

3. The advantage of the anchoring system of the prestressed carbon plate is that its mechanical properties are very good, which can make the carbon plate evenly stressed.

4. Make full use of high-strength carbon fiber composite materials to avoid premature peeling of carbon fibers, effectively reduce the width of structural cracks and limit the formation of cracks.

5. The prestressed carbon plate reinforcement on the bridge directly improves the bending stiffness and bearing capacity of the structure and reduces the structural deformation. These are the key points of bridge reinforcement for bridges.

With the emergence of the prestressed carbon plate reinforcement method, everyone has a new choice in bridge reinforcement, and it is a good new choice. Its advantages are obvious, it has a better effect on bridges, and it is a reinforcement method worth trying.
