[0024] EMBODIMENT

[0025] Please refer to Figs. 1-3 The present application is a kind of carbon fiber component for reinforcing concrete structure, comprising an embedded component 100, the embedded component 100 comprises a connecting ring 101, a positioning ring 105 fixed to the inner side of the connecting ring 101, a connecting rod 106 fixed to each extension end of the inner ring of the positioning ring 105, a positioning ball 102 fixed to the other end of the connecting rod 106, a connecting rod one 104 connecting adjacent positioning balls 102 in the same layer, and a connecting rod two 103 connecting adjacent positioning balls 102 in different layers, a plurality of screw holes are formed on the circumferential side of the positioning ball 102, and the screw holes are connected with the connecting rod one 104 and the connecting rod two 103 end threaded adaptation.

[0026] The connecting rod 106 is a key component for force transmission, one end of the connecting rod 106 is fixed to the positioning ring 105, the other end is connected with the positioning ball 102, the positioning ring 105 is located in the inner side of the connecting ring 101, which provides an accurate installation position for the connecting rod 106, which helps to maintain the geometric stability of the whole system, so that the force can be evenly distributed on the whole reinforcing network, the connecting ring 101 not only plays a role in fixing the whole reinforcing system, but also the screw holes formed on the edge allow the connecting rod one 104 and the connecting rod two 103 to be connected with the embedded steel bars in the concrete structure through fasteners (such as screws or bolts), ensuring the close combination between the reinforcing system and the original structure, preventing slipping when stressed;

[0027] The positioning balls 102 and the connecting rod one 104 in the same layer cross to form a hexagonal reinforcing layer, and the multiple hexagonal reinforcing layers form a spatial reinforcing system through the connecting rod two 103.

[0028] Specifically, the embedded component 100 is embedded in the concrete structure, and the connecting ring 101 in the embedded component 100 at the edge is fixed with the reinforcing structure embedded in the concrete structure through a fastener, and the connecting ring 101 is provided with a threaded hole at the edge, and the connecting ring 101 in the adjacent embedded component 100 is fixed through a fastener.

[0029] Further, the connecting rod one 104, the connecting rod two 103 and the connecting rod 106 are all carbon fiber materials, the connecting rod one 104 is responsible for building a hexagonal grid in a plane, and the connecting rod two 103 realizes the connection between different height levels, creating a three-dimensional space frame, improving the overall rigidity and stability of the structure, and the selection of carbon fiber material means that these rods have high tensile strength and elastic modulus, which can provide great support force without significantly increasing the weight; the positioning ball 102 is a solid structure, and the surface of the positioning ball 102 is coated with a corrosion-resistant layer, the solid structure of the positioning ball 102 can withstand a large compression load, and the corrosion-resistant coating on the surface increases its ability to resist environmental erosion, and a plurality of threaded holes are provided around each positioning ball 102 for threaded connection with other connecting rods to form a solid node.

[0030] When an external force is applied to the concrete structure, the embedded component 100 transmits the force to the positioning ball 102, which then distributes it to the surrounding connecting rods. Due to the use of a multi-layer hexagonal reinforcement layer space reinforcement system, any point receiving pressure will be quickly dispersed to a large area of reinforcement units, effectively preventing local damage. Even if the concrete structure has a small crack, the space reinforcement system can absorb and redistribute the stress from the crack, preventing further expansion of the crack. This is because the hexagonal grid structure itself has a certain flexibility and adaptability, and can adjust itself to a certain extent to cope with deformation.

[0031] Suppose this component is used in a bridge reinforcement project. First, according to the specific size and shape of the bridge, customize the corresponding specifications of the embedded component 100, then arrange these components according to the predetermined position and spacing before pouring the new bridge deck, and firmly combine them with the original steel mesh through the threaded holes on the connecting ring 101. Once the concrete solidifies, a complete carbon fiber reinforcement network is formed, which will greatly improve the carrying capacity and safety of the bridge.
