Indented high-strength steel fiber
The invention relates to an indented high-strength steel fiber which comprises a high-strength steel fiber, at least two pairs of indentations are axially arranged on the high-strength steel fiber, and each pair of indentations is distributed on two opposite sides of the high-strength steel fiber. The high-strength steel fiber is provided with the paired indentations, and the paired indentations are respectively positioned on two opposite sides of the high-strength steel fiber, so that the defects that the high-strength steel fiber is easy to bend along the length direction and is easy to wind during use due to adoption of single-side indentations are avoided; and meanwhile, the problem that the high-strength steel fibers are easy to deform in the length direction to be pulled out when being pulled is solved, the effect of the indentation can be fully exerted, the anchoring force of the high-strength steel fibers and concrete is increased, and the performance of the steel fiber concrete is improved.
本发明涉及一种压痕高强钢纤维，压痕高强钢纤维包括高强钢纤维，高强钢纤维上轴向设有至少两对压痕，每对压痕分布在高强钢纤维相对的两侧。本发明在高强钢纤维上设置成对的压痕，且成对的压痕分别位于高强钢纤维相对的两侧，既避免了采用单侧凹痕导致高强钢纤维容易沿长度方向弯曲和使用时容易缠绕的缺陷，同时也防止出现高强钢纤维受拉时容易沿长度方向产生变形而拔出的问题，能够充分发挥压痕的作用，增加高强钢纤维与混凝土的锚固力，有利于提高钢纤维混凝土的性能。
