The invention relates to the field of building materials, and particularly relates to a novel environment-friendly glass fiber reinforced plastic reinforcing material. The reinforcing material comprises a reinforcing material body and an overlap joint part, wherein the reinforcing material is in a non-closed ring shape, the overlap joint part is connected to the two ends of the reinforcing material body, one end of the rebar material body is bent and then connected with the other end of the reinforcing material body to form a whole through the overlap joint part, the outer diameter of the twoends of the reinforcing material body is smaller than the inner diameter of the overlap joint part, the overlap joint part is connected with the reinforcing material body through bolts, threads are arranged on the outer surface of the reinforcing material body, the section of the reinforcing material body is in a regular pattern such as round, regular hexagon and square. According to the novel environment-friendly glass fiber reinforced plastic reinforcing material, a cutter head is protected, the weight is a quarter of that of a reinforcing steel bar with the same specification, so that the construction is easier, and then the labor intensity of a worker is reduced; and the novel reinforcing material can replace the original reinforcing steel bar to serve as a linking wall, and the temporary supporting effect is good.
