る。Therefore, if the reinforcing bar spacer (a) is pushed in by fitting the reinforcing bar insertion groove (4) of the reinforcing bar spacer (a) at an appropriate position of the reinforcing bar (A), the stopper (8) of the reinforcing bar spacer (a) is pushed. ), (8) the protruding tip into the rebar insertion groove (4) bends outward due to elasticity and the protruding tip opens while the stoppers (8) and (8) pass through the reinforcing bar (A). Then, the reinforcing bar spacer (a) descends, the upper end of the reinforcing bar insertion groove (4) fits into the reinforcing bar (A), the reinforcing bar (A) reaches the center of the reinforcing bar spacer (a), and the stopper (8 ), (8) protruding into the rebar insertion groove (4) is elastically restored, and the stopper (8),
The tip edge of (8) contacts or approaches the peripheral surface of the reinforcing bar (A), and the reinforcing bar spacer (a) is fitted to the reinforcing bar (A).
従つて、上記のように操作して鉄筋（Ａ）に適当間隔で
所要数の鉄筋スペーサー（ａ）を取付けてゆくと、鉄筋
（Ａ）は常に鉄筋スペーサー（ａ）の中心位置に保持さ
れる。Therefore, when the required number of reinforcing bar spacers (a) are attached to the reinforcing bar (A) at appropriate intervals by the above-described operation, the reinforcing bar (A) is always held at the center position of the reinforcing bar spacer (a). .

る。After that, if the weir plate (C) is built by applying it to the outer surface of several rebar spacers (a) to assemble the form, the rebar (A),
(B) is positioned with a cover thickness (L) formed inside the barrier plate (C). Therefore, when concrete is placed in the space inside the barrier plate (C), the concrete enters the reinforcing bar insertion groove (4) of the body (6) of the reinforcing bar spacer (a), and the reinforcing bar spacer (a) is inserted into the concrete. ) And the reinforcing bars (A) and (B) are embedded to construct the skeleton (D).
（考案の効果） この考案の鉄筋スペーサーは、下記のような顕著な効果

（１） 鉄筋スペーサーを鉄筋に押込めば、そのストツ
パが開閉作動して鉄筋スペーサーは取付けられ、僅小の
力で安楽に操作して鉄筋スペーサーをワンタツチで簡易
迅速に取付けることができ、取扱い易くて作業能率を向
上する。(1) If the reinforcing bar spacer is pushed into the reinforcing bar, the stopper opens and closes and the reinforcing bar spacer is attached. The reinforcing bar spacer can be operated easily with a small amount of force, and the reinforcing bar spacer can be easily and quickly attached with one touch, making it easy to handle. Improve work efficiency.
（２） 本体に基端部が拡開したあり溝を設け、基端に
横棒状膨大部を形成したストツパの先端部を上記本体の
鉄筋挿入溝内に適宜に突出させ基部を上記あり溝内に挿
入固定して鉄筋スペーサーを構成するから、その本体と

スペーサーの本体が鉄筋に対して斜めにずれても、スト
ツパがずれ動いたり外れたりして鉄筋スペーサーが落下
するおそれは無い。(2) The main body is provided with a dovetail groove with an expanded base end portion, and the distal end portion of the stopper having a lateral bar-shaped enlarged portion formed at the base end is appropriately projected into the rebar insertion groove of the main body so that the base portion is in the dovetail groove. Since the reinforcing bar spacer is constructed by inserting and fixing it in the body, the fitting and fixing of the main body and the stopper are sure and firm. Therefore, (a) Even after the reinforcing bar spacer is attached to the reinforcing bar, even if the main body of the reinforcing bar spacer is slanted with respect to the reinforcing bar, the stopper does not move or come off and the reinforcing bar spacer does not drop.
（ロ） 配筋後における鉄筋スペーサーの再配置のため
の移動，コンクリート打設のときのコンクリートの流
動，コンクリート打設後における打設コンクリートの振
動等によつてストツパがずれ動いたり脱落することは無
く、作業を安楽適確になし得る。(B) The stoppers may not move or fall off due to the movement of the rebar spacers for repositioning after reinforcement, the flow of concrete during concrete placement, or the vibration of the placement concrete after placing concrete. You can do the work easily and accurately.
（３） 鉄筋スペーサーの外周が円形で、その中心に鉄
筋が位置するから、鉄筋スペーサーが若干回動しても鉄
筋スペーサーによつて常に確実に鉄筋のかぶり厚さを保
持し得る。(3) Since the outer circumference of the reinforcing bar spacer is circular and the reinforcing bar is located at the center thereof, even if the reinforcing bar spacer slightly rotates, the reinforcing bar spacer can always surely maintain the covering thickness of the reinforcing bar.
（４） 鉄筋スペーサーの本体をセラミツクスにより形
成したから、鉄筋スペーサーは、 （イ） 高温度に耐えて火災等の熱に強い。(4) Since the main body of the reinforcing bar spacer is made of ceramics, the reinforcing bar spacer is (a) resistant to high temperatures and resistant to heat such as fire.
（ロ） 硬く、圧縮強度が大で、抵抗性がある。(B) Hard, high compressive strength, and resistant.
（ハ） 床堰板上に配筋する場合に鉄筋の重みによる強
い圧縮を受けても、圧縮強度が高いために薄肉の本体で
十分に鉄筋を支持し得て実用上有益である。(C) Even when the reinforcement is subjected to strong compression due to the weight of the reinforcement when arranging the reinforcement on the floor dam, the thin body can sufficiently support the reinforcement and is practically useful.
（ニ） 気温の変化による膨張および収縮が極めて少な
くて躯体に弊害を及ぼすことが無い。(D) Expansion and contraction due to changes in temperature are extremely small, and there is no adverse effect on the body.
（５） 鉄筋スペーサーの本体のストツパを取付けるあ
り溝をその本体の鉄筋挿入溝の側面と直角方向に設けた
から、上記本体がセラミツクスでもそれに鋭角の角部が
無いため、本体は丈夫でそれを破損するおれが無い。(5) Since the dovetail groove for attaching the stopper of the main body of the reinforcing bar spacer is provided in the direction perpendicular to the side surface of the reinforcing bar insertion groove of the main body, even if the above main body is ceramic, there are no sharp corners, so the main body is strong and damaged. I have no desire to do it.
（６） 鉄筋スペーサーの本体の両側片の先端部を面取
りしたから、上記本体がセラミツクスでもその両側片の
先端部が破損することは無い。(6) Since the tip portions of both side pieces of the main body of the reinforcing bar spacer are chamfered, the tip portions of the both side pieces are not damaged even when the main body is ceramics.
（７） 構造が簡単で、容易安価に製作できる。(7) It has a simple structure and can be manufactured easily and inexpensively.
