スラブである。 3 is a slab weir plate for the formwork of a reinforced concrete structure, 4 and 5 are upper and lower reinforcing bars placed above the weir plate 3 with a cover thickness L and arranged in a grid pattern, and 6 is concrete being poured on the weir plate 3. It is a concrete slab constructed by

て静止する。 Next, its effect will be explained. Due to the formation of the groove 2, the center of gravity of the reinforcing bar spacer a is located on the opposite side of the groove 2 from the center of the cylindrical body 1, so place the reinforcing bar spacer a on the weir plate 3 as shown in Fig. 4. Then, the reinforcing bar spacer a always stands still with the groove 2 facing upward.

して鉄筋４，５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 3, and after placing the reinforcing bars 5 across the grooves 2 of the reinforcing bar spacers a, the reinforcing bars 4 are placed orthogonally on the reinforcing bars 5. I'll put it on. After that, although not shown, if the intersections of the reinforcing bars 4 and 5 are fixed by binding them with wire, etc., a cover thickness L is formed above the weir plate 3, and the reinforcing bars 4 and 5 are installed in a cross-shaped structure. Ru.

構築される。 Therefore, when concrete is placed on the weir plate 3, the reinforcing bar spacer a and the reinforcing bars 4 and 5 are buried in the concrete, and a concrete slab 6 is constructed.
なお、鉄筋スペーサーａの中心にその両側のコ
ンクリートの連結用の通孔を穿つてもよい。 Note that a through hole may be made in the center of the reinforcing bar spacer a for connecting the concrete on both sides 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 groove from the center of the cylindrical body, so no matter how you place the reinforcing bar spacer, and even if it rolls, the reinforcing bar spacer will always remain in place. The concave groove points upward and it stands still. for that,
In addition to making it easy to place the reinforcing bars in the recessed grooves of the reinforcing bar spacers, 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 carried out 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なく、鉄筋ス
ペーサーの取付けが確実である。 (c) Concrete easily enters under 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, so that the reinforcing bar spacer can be installed reliably.
(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) 構造が簡単であるために、製作が容易で、製
造コストが低い。(2) Since the structure is simple, it is easy to manufacture and the manufacturing cost is low.
