As an alternative embodiment, the auxiliary bars 10 and the main bars 20 are both cylinder-like bars.
By arranging the auxiliary ribs 10 and the main ribs 20 as cylindrical ribs, on one hand, the mechanical properties of the auxiliary ribs and the main ribs in the radial direction are uniform; on the other hand, a relatively obvious groove 30 can be formed between the cylindrical surfaces of the auxiliary bars 10 and the cylindrical surfaces of the main bars 20 and between the cylindrical surfaces of two adjacent main bars 20, so that the mechanical interlocking performance between the composite bars and the concrete can be optimized.
As an alternative embodiment, a gap is reserved between two adjacent main bars 20.
The volume of the groove 30 is further enlarged by reserving a gap between two adjacent main bars 20, so that the mechanical interlocking performance between the composite bars and the concrete is further improved; and structural influence between the adjacent main beads 20 can be prevented.
According to another exemplary embodiment of the present invention, there is provided a method for manufacturing a high-adhesion carbon fiber composite bar for a cement concrete structure, including the steps of:
