The present invention relates to a steel reinforcement used for concrete structure construction. In order to allow coupling grooves (11, 12) to be alternately positioned on upper, lower, left, and right parts in a longitudinal direction, the steel reinforcements (10) are formed at a predetermined interval and are assembled with a structure wherein the coupling grooves of the steel reinforcements constructed in a lattice shape are coupled to each other. Thus, the steel reinforcements are constructed with a constant and accurate assembly interval, are conveniently assembled, and have excellent structural assembly rigidity and concrete adhesion properties; thereby enabling high quality construction. |
