PROBLEM TO BE SOLVED: To provide a spacer for rebar arrangement by which displacement after arrangement on a surface where concrete is to be placed is hardly caused, main reinforcements are arranged easily, quickly and accurately, an appropriate covering depth is secured, and workability and integration performance with concrete are improved.SOLUTION: The spacer 10 for rebar arrangement includes a supporting member 11 having a linear shape, and a plurality of mortar block bodies 12 fixed to the supporting member 11 at predetermined intervals to hold the supporting member 11 in the state of being spaced from the surface F1, where the concrete is to be placed, by a predetermined distance. Each of the block bodies 12 has a supporting part 12a projecting from an outer periphery of the supporting member 11 to the surface F1. The supporting part 12a has a shape of a wedge sharpened toward the surface F1, and is fixed in the state that the supporting member 11 is held in a channel 12b formed on the opposite side of the supporting part 12a. Anti-rust coating is applied on the outer peripheral surface of the supporting member 11. |
