途には不向きであった。2. Description of the Related Art Reinforcing spacers of a type that can be fixed to a reinforcing bar are known, and various types of structures have already been proposed, but those of the conventional structure generally have a complicated structure and are expensive to manufacture. In many cases, clip means is employed as the fixing means. However, in the conventional method, the mounting direction and the detaching direction are the same, and the clip force is not so strong. When applied to a reinforcing bar, it may slip off under its own weight or may come off or rotate under the pressure of concrete. In recent years, a construction method has been implemented in which pre-assembled reinforcing bars for beams and slabs are moved and installed using a crane, etc.
The conventional type is not suitable for such a use because of its unstable fixation.

提供できる。The reinforcing bar spacer according to the present invention is a bent product of one wire as shown in the figure, and can be provided at a low cost with a simple structure.
【００１２】線材としては、金属とりわけ比較的バネ性
能の大きい鉄製線材が適当である。As the wire, a metal, especially an iron wire having a relatively large spring performance is suitable.
【００１３】本発明による鉄筋スペーサを鉄筋ａに対し

下端のピッチ間隔部４（図２参照）を通じて鉄筋ａ内に
挿入する。When the reinforcing bar spacer according to the present invention is fixedly set to the reinforcing bar a, first, the spiral annular portion 3 is inserted into the reinforcing bar a through the pitch interval portion 4 at its lower end (see FIG. 2).
【００１４】この挿入状態においては、図２から明らか
なような螺旋環状部３の中心軸線３ａと鉄筋ａの中心線
ａ1 とは直交している。[0014] In this insertion state is perpendicular to the center line a 1 of the central axis 3a and rebar a obvious such spiral annular portion 3 from FIG.

旋環状部３内に貫通保持される。When the spacer of the present invention is rotated 90 ° about the center line 5 shown in FIG. 1 in the inserted state shown by the imaginary lines in FIGS. 1 and 2, the two center axes 3 as shown in FIG.
a and a 1 completely coincide with each other, and the reinforcing bar a is held through the spiral annular portion 3 as shown in FIG.
【００１６】螺旋環状部３に貫通保持された鉄筋ａは本
発明スペーサが９０°回転して当初の位置に戻らない限
