Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、鉄筋スペーサーに関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a reinforcing bar spacer.
（従来の技術と発明が解決しようとする課題）現場打ち
の鉄筋コンクリート構造の構築物においては、配筋作業
と型枠組付作業が必須のものであり、外部側に配筋され
た各鉄筋については、所定の被り厚さを確保することが
Ｒａ付けられている。(Problems to be Solved by the Prior Art and the Invention) In a cast-in-place reinforced concrete structure, reinforcement work and formwork assembly work are essential, and for each reinforcement placed on the outside, Ra is set to ensure a predetermined covering thickness.
そこで、現場作業においては、コンクリート打設前に型
枠面と鉄筋との間に前記被り厚さに相当する所定の空間
を確保するため、鉄筋スペーサーが一般的に使用されて
いる。Therefore, in field work, reinforcing bar spacers are generally used in order to secure a predetermined space corresponding to the above-mentioned covering thickness between the formwork surface and the reinforcing bars before concrete pouring.
しかしながら、従来の鉄筋スペーサーは、１１１に型枠
−りに載置するだけのものであるため、階段のように傾
斜した部分の配筋作業では、鉄筋が鉄筋スペーサーから
脱落したり、移動したりして適正な被り厚さを確保する
ことが困難となっていた。However, since conventional reinforcing bar spacers are simply placed on formwork, reinforcing bars may fall off or move from the reinforcing bar spacers when working on sloping sections such as stairs. Therefore, it has become difficult to ensure an appropriate covering thickness.
また、かかる問題は、壁や梁あるいは屋根の配筋作業、
さらにはスラブのベンド配筋等においても同様であった
。In addition, such problems can be caused by reinforcing work on walls, beams, or roofs.
Furthermore, the same was true for slab bend reinforcements, etc.
本発明は、かかる従来の課題を解決することを目的とす
るものである。The present invention aims to solve such conventional problems.
（課題を解決するための手段）
上記目的を達成するため、本発明に係る鉄筋スペーサー
においては、型枠に対して所定の被り厚さを確保して鉄
筋を弾性的に挟持しつる保持部と、型枠への釘打ち固定
のための釘穴が形成された固定部とを備えてなることに
より鉄筋の脱落、移動を確実に防ＩＬ、シたことを特徴
とするものである。(Means for Solving the Problems) In order to achieve the above object, in the reinforcing bar spacer according to the present invention, the reinforcing bar is elastically clamped while ensuring a predetermined covering thickness with respect to the formwork. , and a fixing part in which a nail hole is formed for nailing fixation to the formwork, thereby reliably preventing the reinforcing bars from falling off or moving.
（実施例） 以下、本発明の好適な実施例を図面により説明する。(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
第１図乃至第４図は、本発明の一実施例を示すものであ
り、本実施例に係る鉄筋スペーサー１は、保持部２と固
定部３とを備えてなるものである。1 to 4 show an embodiment of the present invention, and a reinforcing bar spacer 1 according to this embodiment includes a holding part 2 and a fixing part 3. As shown in FIG.
＋’＋：ｉ記保持部２は、型枠４に対して所定の被り厚
さを確保して鉄筋５を弾性的に挟持するだめのものであ
り、本実施例では座台６と、該座台６上面に固着された
弾性挟持片７とからなる。+'+: The i holding part 2 is for elastically holding the reinforcing bar 5 while ensuring a predetermined covering thickness with respect to the formwork 4, and in this embodiment, the holding part 2 is for holding the reinforcing bar 5 elastically. It consists of an elastic clamping piece 7 fixed to the upper surface of the seat 6.
弾性挟持片７は、所定径の鉄筋５を上面から抑圧、嵌合
するとその弾性変形により該鉄筋５を挟持、固定しつる
ようになっており、前記座台６は、弾性挟持片７に鉄筋
５を挟持した状態で型枠４−１Ｈに載置した場合に、必
要とされる被り厚さＷを確保しつるようにその高さ寸法
が設定されている。The elastic clamping piece 7 suppresses a reinforcing bar 5 of a predetermined diameter from the upper surface, and when fitted, clamps and fixes the reinforcing bar 5 due to its elastic deformation. The height dimension is set so as to ensure the required covering thickness W when the mold 4-1H is placed with the mold 5 sandwiched therebetween.
前記固定部３は、その下面３ａが型枠４に当接されるよ
うになっており、本実施例では本体８の４個所に該型枠
４への釘打ち固定のための釘穴９が形成されている。The lower surface 3a of the fixing part 3 is brought into contact with the formwork 4, and in this embodiment, the main body 8 has four nail holes 9 for fixing to the formwork 4 by nailing. It is formed.
しかして、前記各釘穴９は、第３図に示すように本実施
例では、円筒形状のボス１０の中央部に形成されており
、各ボス１０は、その上面が本体８の上面よりも所定寸
法分凹陥して配設されるとともに、各ボス１０の下面は
１本体８の下面と面一に設定されている。As shown in FIG. 3, each nail hole 9 is formed in the center of a cylindrical boss 10 in this embodiment, and the upper surface of each boss 10 is higher than the upper surface of the main body 8. The bosses 10 are recessed by a predetermined dimension, and the lower surface of each boss 10 is flush with the lower surface of the main body 8 .
また、各ボスｌＯは、本体８と脆弱な連結部１１でのみ
連結されており、後述の如くボス１０に下方への引張力
が作用すると、本体８から容易に分離しつるようになっ
ている。Further, each boss 1O is connected to the main body 8 only by a weak connecting portion 11, and when a downward tensile force is applied to the boss 10 as described later, it is easily separated from the main body 8 and hangs. .
かかる構成からなる本実施例においては、例えば、第４
図に示すような階段部分の鉄筋５を型枠４」二に配筋す
る場合において、まず、固定部３の各釘穴９に型枠４に
向けて釘１２を打ち込み、所定個数の鉄筋スペーサー１
を型枠４−［ユの所定位置に各々固定する。In this embodiment having such a configuration, for example, the fourth
When arranging the reinforcing bars 5 of the stairway part on the formwork 4'' as shown in the figure, first, nails 12 are driven into each nail hole 9 of the fixing part 3 toward the formwork 4, and a predetermined number of reinforcing bar spacers are inserted into the formwork 4. 1
are respectively fixed at predetermined positions in the formwork 4-[Y].
しかる後に、各鉄筋スペーサー１の弾性挟持片７に対応
位置の鉄筋５を嵌合、挟持させれば、上記の如く、鉄筋
５は所定の被り厚さＷを確保して所定位置に強固に設置
され、階段部分のような傾斜した配筋作業であっても、
鉄筋５が鉄筋スペーサー１から脱落したり、移動したり
するおそれが全くな（なる。After that, by fitting and clamping the reinforcing bars 5 at the corresponding positions to the elastic clamping pieces 7 of each reinforcing bar spacer 1, the reinforcing bars 5 are securely installed at a predetermined position while ensuring a predetermined covering thickness W, as described above. Even in sloped reinforcement work such as stairs,
There is no risk that the reinforcing bars 5 will fall off or move from the reinforcing bar spacer 1.
また、壁や梁あるいは屋根の配筋作業、さらにはスラブ
のベンド配筋等においても同様な作用効果を奏しうるも
のである。Further, similar effects can be achieved in reinforcement work for walls, beams, or roofs, and even in bend reinforcement work for slabs.
さらに、本実施例では、現場打ちコンクリートの打設硬

先端部１２ ａが：コンクリート面から突出した状態と
なるので、該釘１２の先端部１２ａをベンチなどの適宜
工具により下方に引っ張ると、上記したボス１０と本体
８を連結している脆弱な連結部１１が破断して、釘１２
をボス１０と共にコンクリート部分から容易に除去する
ことができる。Furthermore, in this embodiment, when the formwork 4 is removed from the cast-in-place concrete after it has hardened, the tips 12a of the nails 12 protrude from the concrete surface at the positions of the respective nail holes 9. When the tip 12a of the nail 12 is pulled downward with an appropriate tool such as a bench, the fragile connecting portion 11 connecting the boss 10 and the main body 8 breaks, and the nail 12
can be easily removed from the concrete part together with the boss 10.
よって、釘１２の先端部１２ａから錆が発生する不具合
を防１［〕することができる。Therefore, the problem of rust occurring from the tip 12a of the nail 12 can be prevented.
なお１本発明は上記実施例に限定されるものではなく、
第５図に示す他の実施例のように、弾性挟持片７の外周

に成形することにより保持部２を形成し、該保持部２を
、平板状をなし所定個数の釘穴９が穿設された固定部３
に固定することにより鉄筋スペーサー１を形成するよう
にしてもよい。Note that the present invention is not limited to the above embodiments,
As in the other embodiment shown in FIG. The part 2 is a fixed part 3 having a flat plate shape and having a predetermined number of nail holes 9.
The reinforcing bar spacer 1 may also be formed by fixing to.
なお、この場合に、保持部２は固定部３と脱着自在に形
成しておけば、通常のスラブ筋専の配筋場所では保持部
２のみを使用するようにして、共用することもできる。In this case, if the holding part 2 is formed to be detachable from the fixing part 3, only the holding part 2 can be used in a place where reinforcement is normally reserved for slab reinforcement.
また、上記各実施例では、保持部２及び固定部３は、い

ない範囲内で種々の変形例が可能なことは言“うまでも
ない。Further, in each of the above embodiments, the holding part 2 and the fixing part 3 are both molded from synthetic resin, but in addition to this, either one or both of the holding part 2 and the fixing part 3 can be made of synthetic resin. It goes without saying that various modifications are possible without departing from the spirit of the present invention, such as being made of metal.
