[0002] Rebar is a key material used in reinforced concrete structures in construction projects, primarily enhancing concrete's tensile, bending, and shear resistance. Rebar is typically made from carbon steel or low-alloy steel, produced through processes such as hot rolling, cold rolling, or cold drawing. Rebar spacing refers to the distance between the centers of adjacent bars in construction projects. The spacing between rebars affects the concrete structure's load-bearing capacity and crack control.

[0003] Publication number CN 213204707 U discloses a rebar spacing limiter. This device controls rebar spacing through multiple rebar spacing fixtures, achieving standardized control of rebar spacing. This device is reliable, robust, and precise.
