The tensile strength of the steel bar is 2-3 times of that of the steel bar with the same diameter, and the density of the steel bar is 1/4 of that of the steel bar; however, the existing anchor rod is influenced by the production process, the strength in the axial direction is high, and the stress strength in other directions is low.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a basalt fiber anchor rod body which is high in overall structural strength and capable of ensuring the structural strength after stress in all directions.
According to the basalt fiber anchor rod body, the basalt fiber layer with a woven or felt structure is firstly formed outside the rod body in a thermal compounding manner, and the woven layer is woven in a vertical manner and is arranged along the axial direction and the circumferential direction of the rod body, so that the axial stress and the circumferential stress of the rod body can be greatly enhanced; meanwhile, the continuous basalt twistless roving is utilized to weave a first protective layer with a clockwise inclination of not less than 15 degrees, and then the continuous basalt twistless roving is utilized to weave a second protective layer with a counterclockwise inclination of not less than 15 degrees, so that the secondary reinforcement of the outer part of the whole rod body is completed; the strength of the whole structure is greatly improved, when the rod body is stressed obliquely, the first protective layer and the second protective layer disperse the stress of the rod body through self compression and self tension respectively, so that the strength of the whole rod body is greatly improved; the concrete structure is as follows: the composite type basalt fiber-vinyl epoxy resin composite rod comprises a rod body which is formed by compounding basalt fibers and vinyl epoxy resin, wherein a structural layer, a first protective layer and a second protective layer are sequentially arranged outside the rod body; the structural layer is fixed outside the rod body by winding and pasting basalt fiber checkered cloth or felt; the first protective layer is fixed outside the structural layer by clockwise winding and pasting of continuous basalt twistless roving; the second protective layer is fixed outside the first protective layer by adopting the reverse-time winding and pasting of continuous basalt twistless roving.
Further, the thickness of the structural layer is not less than 1 mm; the thickness of the first protective layer is not less than 0.5mm, and the thickness of the second protective layer is not less than 1 mm.
Further, the rod body is a solid rod body; inner grooves are arranged at two ends of the inner sleeve; the inner groove is fixedly bonded with the anchor head.
Further, the outer part of the second protective layer is of a constant-pitch spiral structure.
Compared with the prior art, the basalt fiber anchor rod body is high in overall structural strength, and the structural strength of the basalt fiber anchor rod body after stress in all directions can be guaranteed by receiving stress of all angles of the rod body through the structural layer, the first protective layer and the second protective layer respectively.
