[0001] The utility model relates to the field of steel bar binding, in particular to a steel bar binding fastener. Background Art

[0002] In the process of construction, the binding of steel bars is a key step. The traditional method of binding steel bars is manual binding. This binding method often results in the steel bars being loose, easy to loosen, and the steel bars being misaligned or relatively skewed. In the actual construction process, when construction workers step on and pour concrete, these external force impacts will make the steel bar binding become looser or the position shift.

[0003] For high-precision prefabricated structures, the traditional wire tying of steel bars often fails to meet the design requirements, and the position of the steel bars is prone to deviation, which will make it difficult to align the steel bars and grouting sleeves during assembly, and even lead to installation failure. Therefore, in prefabricated structures, it is urgent to use a firmly tied steel bar tying fastener to replace the traditional wire tying steel bars, so that the steel bars are accurately positioned and firmly tied, which is an urgent problem to be solved.
