成する。(Example) The structure of one embodiment of this invention shown in the drawings will be described. A is a reinforcing bar spacer made of ceramics, synthetic resin, etc., and has a reinforcing bar placement groove 2, which is arc-shaped in cross section and perpendicular to the center line, at the upper part of the outer periphery of a cylindrical body 1 and in the center of the length direction.
A horizontal groove 3 is provided in the center of both sides of the outer periphery of the cylindrical body 1 in the direction of the center line, and five horizontal grooves 4 are provided at appropriate intervals on both end faces to form a reinforcing bar spacer a.
５は鉄筋コンクリート構築物の型枠のスラブ堰

スラブである。 5 is a slab weir plate for the formwork of a reinforced concrete structure, 6 and 7 are upper and lower reinforcing bars arranged in a grid pattern with a cover thickness L above the weir plate 5, and 8 is concrete being poured on the weir plate 5. It is a concrete slab constructed by
次にその作用を説明する。鉄筋スペーサーａ
は、凹溝２の形成によつてその重心が円柱体１の
中心線よりも凹溝２と反対側に位置するので、第
５図に示すように鉄筋スペーサーａを堰板５上に
置くと、鉄筋スペーサーａは常に凹溝２が上方に
なつて静止する。 Next, its effect will be explained. Rebar spacer a
Due to the formation of the groove 2, its center of gravity is located on the opposite side of the center line of the cylindrical body 1 from the groove 2, so if the reinforcing bar spacer a is placed on the weir plate 5 as shown in FIG. , the reinforcing bar spacer a always stands still with the groove 2 facing upward.
従つて、堰板５上に鉄筋スペーサーａを適当間
隔で直列に並置し、その鉄筋スペーサーａの凹溝
２内にわたして鉄筋７を載せた後、該鉄筋７上に
鉄筋６を直交状態に載せる。その後、図示してな
いが、鉄筋６，７の交差部を番線で結束する等し
て固定すれば、堰板５の上方にかぶり厚さＬを形
成して鉄筋６，７が井桁状に施設される。 Therefore, reinforcing bar spacers a are arranged in series at appropriate intervals on the weir plate 5, and after placing the reinforcing bars 7 in the grooves 2 of the reinforcing bar spacers a, the reinforcing bars 6 are placed on the reinforcing bars 7 in a perpendicular state. I'll put it on. After that, although not shown, if the intersections of the reinforcing bars 6 and 7 are tied together with wires and fixed, a cover thickness L is formed above the weir plate 5, and the reinforcing bars 6 and 7 are arranged in a cross-shaped structure. be done.
そこで、堰板５上にコンクリートを打設する
と、そのコンクリートが鉄筋スペーサーａの横溝
３，４内に入り込み、該コンクリート内に鉄筋ス
ペーサーａおよび鉄筋６，７が埋没してコンクリ
ートスラブ８が構築される。 Therefore, when concrete is placed on the weir plate 5, the concrete enters the horizontal grooves 3 and 4 of the reinforcing bar spacer a, and the reinforcing bar spacer a and the reinforcing bars 6 and 7 are buried in the concrete, thereby constructing a concrete slab 8. Ru.
また、その際、鉄筋スペーサーａの外周面の下

クリートの押圧により徐々に鉄筋スペーサーａの
外周面に沿つて上昇し横溝３内に入つてその中に
収容され、コンクリートと鉄筋スペーサーａとが
隔絶状態になるのを防止される。 At that time, water particles in the concrete that come into contact with the lower half of the outer circumferential surface of the reinforcing bar spacer a gradually rise along the outer circumferential surface of the reinforcing bar spacer a due to the pressure of the concrete, enter the horizontal groove 3, and enter into the horizontal groove 3. This prevents the concrete and the reinforcing steel spacer a from becoming isolated.
なお、鉄筋スペーサーａの中心にその両端面の
コンクリートの連結用通孔を穿つてもよい。 In addition, a through hole may be bored in the center of the reinforcing bar spacer a to connect the concrete on both end faces thereof.
（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
著な効果を有する。(Effects of the invention) The reinforcing bar spacer of this invention has the following remarkable effects.
(1) 鉄筋スペーサーが円柱状で、その外周面上に
鉄筋載置用凹溝を設けてある。従つて、
(イ) 鉄筋スペーサーの重心がその円柱体の中心
線よりも凹溝と反対側に位置するので、鉄筋
スペーサーをどのように置き、また、それが
たとえ転がつても、鉄筋スペーサーは常にそ
の凹溝が上方になつて静止する。そのため
に、鉄筋を鉄筋スペーサーの凹溝内に載せ易
い上に、鉄筋のかぶり厚さは一定で、鉄筋を
常に確実にかぶり厚さに保持して作業を正確
に行うことができる。(1) The reinforcing bar spacer is cylindrical and has grooves for placing reinforcing bars on its outer circumferential surface. Therefore, (a) The center of gravity of the reinforcing bar spacer is located on the opposite side of the center line of the cylindrical body from the concave groove, so no matter how you place the reinforcing bar spacer, and even if it rolls, the reinforcing bar spacer will not move. It always stands still with its groove pointing upwards. Therefore, it is easy to place the reinforcing bars in the recessed groove of the reinforcing bar spacer, and the covering thickness of the reinforcing bars is constant, so that the reinforcing bars can always be reliably maintained at the covering thickness and work can be performed accurately.
(ロ) 鉄筋スペーサーの転がりが防止されて安定
性が良い。 (b) The reinforcing bar spacer is prevented from rolling, resulting in good stability.
(ハ) コンクリートが鉄筋スペーサーの下方にも
入り易くてスラブにすができない上に、コン
クリートの硬化後において鉄筋スペーサーが
スラブから下方へとび出すことが無い。 (c) Concrete easily enters below the reinforcing bar spacer and cannot be washed into the slab, and the reinforcing bar spacer does not protrude downward from the slab after the concrete hardens.
(ニ) 鉄筋スペーサーのスラブ下面に露出する部
分は、その円柱体の外周面の下端のみである
から少ない。 (d) The portion of the reinforcing bar spacer exposed on the bottom surface of the slab is small because it is only the lower end of the outer peripheral surface of the cylindrical body.
(2) 鉄筋スペーサーの両端面に数個の横溝を設け
たから、打設するコンクリートが上記数個の横
溝内に入り固まつて鉄筋スペーサーの取付けが
確実である。(2) Since several lateral grooves are provided on both end faces of the reinforcing bar spacer, the concrete to be placed will enter the several lateral grooves and harden, ensuring reliable installation of the reinforcing bar spacer.
(3) 構造が簡単で、容易安価に製作できる。(3) It has a simple structure and can be manufactured easily and inexpensively.
