So how can the carbon fiber plate reinforcement of the building be brought into play?

We know that the elongation of the steel bar at yield is about 0.18%, compared with the elongation of 1.7% when the carbon fiber plate is broken, even without considering the initial deformation of the steel bar (the ideal state of reinforcement when the structure is completely unloaded). The strength that the carbon fiber plate can play is also less than 11%.

Therefore, ordinary carbon plate pasting and strengthening does not take advantage of the high strength of carbon fiber plate. Pre-stressed carbon plate reinforcement makes up for this shortcoming.

Anchorage, which carries the mission of transmitting the prestress on the carbon plate to the entire reinforcement system, is the core component of the entire prestressed carbon plate system. Only effective anchoring of carbon fiber board can take advantage of its high strength. There are many types of anchors, such as: flat anchors, wedge anchors, wave tooth anchors, sika anchors and so on. No matter which kind of anchorage is used, can it meet the requirements of the anchorage efficiency coefficient of GB / T 14370-2015 "anchorage, clamps and connector anchorages for prestressed tendons" not less than 0.95? the answer is negative. When the anchorage breaks the carbon fiber board under tension, it only exerts 50% -80% of the ultimate stress of the carbon fiber board, that is, the anchorage efficiency coefficient is much lower than 0.95.

Therefore, the anchoring efficiency coefficient of the anchorage is expected to increase to above 0.95 only if the common failure modes of the anchorage are resolved.

Through independent research and development, Horse Construction has developed a set of anchor systems with high anchoring performance, safety and stability, and high fatigue resistance, which solves the problem of abnormal damage or failure during the construction of carbon fiber plate.
