Construction material
PROBLEM TO BE SOLVED: To provide a spacer for bar arrangement which can stably support orthogonally-arranged reinforcements in cross points of the reinforcements.SOLUTION: In a spacer for bar arrangement having a lower spacer 1 and an upper spacer 2, the lower spacer 1 and the upper spacer 2 have two leg parts 11, 21, and horizontal bridge parts 12, 22, respectively, the horizontal bridge part 12 of the lower spacer 1 comprises a reinforcement support part 12a and folded parts 12b, 12c, the horizontal bridge part 22 of the upper spacer 2 comprises at least a reinforcement support part 22a and a folded part 22b at left-and-right both sides or either of the left and right of the reinforcement support part 22a, the reinforcement support part 22a of the upper spacer 2 is arranged at a position higher than the reinforcement support part 12a of the lower spacer 1, and when the upper spacer 2 and the lower spacer 1 are arranged so as to be orthogonal in a plane view, the reinforcement support parts 12a, 22a intersect each other unevenly in heights.
