Bond and anchor performance between steel and concrete is one of the basic research questions for concrete structure. It has affected a lot on its structural strength of steel, crack control, reinforcement structure and security structures. Currently, in the reinforced concrete structure, the common method is to use rebar hook. Through 90 ° or 135 ° hooked rebar to some extent enhances rebar performance and reduces the anchor length, but bent or curved arc radius often brings many problems, such as rebar congestion on beam – column joint area, hooked rebars and other rebars interfere with each other, anchor length does not meet the requirements and so on. When using large diameter rebar, these problems become more prominent. CABR developed a patented rebar mechanical anchor technology and has become a good solution to this problem. It can ensure rebar mechanical anchoring performance, optimize steel anchor conditions, and reduce the length of the steel anchor, save steel anchor length. It is convenient, and to improve concrete pouring quality.
