例えばコンクリートを使用して造られる橋梁においては、コンクリートに所定 の耐荷力を与えるためにプレストレスト工法が用いられている。プレストレスト 工法は、コンクリートを打ち込んだ後、所定の引っ張り力で高強度鋼線（以下、 ＰＣケーブルという）を緊張させ、ＰＣケーブルの収縮力によってコンクリート に所定の強度を与えるものである。コンクリート内にはＰＣケーブルを通すため の管状のシースが橋梁の全長にわたって設けられており、ＰＣケーブルがその中 に挿入されるようになっている。 このシースを鉄筋に固定する際、従来は紐或いは番線等を使用していた。 しかし、シースを鉄筋に結び止める手順が複雑であるということに加えて、人 手不足の昨今では熟練技術者の確保が難しいため、不慣れな作業員が作業を進め ていた。これらの原因により、作業時間の浪費は著しく、又手抜き工事の原因に なる恐れもあった。 For example, in a bridge built using concrete, there are certain The prestressing method is used to provide the load-bearing capacity of the building. prestressed The construction method involves pouring concrete into high-strength steel wires (hereinafter referred to as (PC cable) is tensed, and the shrinkage force of the PC cable causes concrete to break down. It gives a predetermined strength to. To pass the PC cable through the concrete A tubular sheath is installed along the entire length of the bridge, and the PC cable runs inside it. It is designed to be inserted into. Conventionally, when fixing this sheath to reinforcing bars, strings or wires were used. However, in addition to the complicated procedure of tying the sheath to the reinforcing steel, In these days of labor shortages, it is difficult to secure skilled technicians, so inexperienced workers are carrying out the work. was. Due to these reasons, work time is wasted significantly and also causes shoddy construction work. There was a fear that it would happen.

本考案を図面に示した実施例に基づき更に詳細に説明する。 図１は本考案の第１の実施例を示す斜視図、図２は使用状態の説明図、図３は 鉄筋を施した橋梁にシース部材を取り付けた状態の説明図である。 符号１はシース取付具を示している。シース取付具１は弾性を有する一本の針 金を屈曲させることによって形成されており、シース嵌入部１０と、鉄筋取付部 である鉄筋掛着部１１，１１ａと、ばね部１２とを備えている。 シース嵌入部１０は下方に開口した逆Ｕ字状に形成されており、シース部材２ を嵌入できるようになっている。 シース嵌入部１０の両下部から鉄筋掛着部１１，１１ａが下方に伸びている。 鉄筋掛着部１１，１１ａは湾曲部１１０，１１０ａと、湾曲部１１０，１１０ａ から上方に伸びる立ち上がり部１１１，１１１ａとから成っている。この鉄筋掛 着部１１，１１ａは互いに反対方向に折り曲げられているので、それぞれ異なる 側から鉄筋３に掛かるようになっている。又、鉄筋掛着部１１ａの立ち上がり部 １１１ａは鉄筋掛着部１１の立ち上がり部１１１に比べて低く形成されている。 ばね部１２はシース嵌入部１０の外側上部に設けられており、逆α（アルファ ）字状である。 The present invention will be explained in more detail based on embodiments shown in the drawings. Fig. 1 is a perspective view showing the first embodiment of the present invention, Fig. 2 is an explanatory view of the state of use, and Fig. 3 is a perspective view showing the first embodiment of the present invention. It is an explanatory view of a state where a sheath member is attached to a bridge provided with reinforcing bars. Reference numeral 1 indicates a sheath fitting. The sheath fitting 1 is a single elastic needle. It is formed by bending gold, and has a sheath insertion part 10 and a reinforcing bar attachment part. It includes reinforcing bar hanging parts 11, 11a and a spring part 12. The sheath insertion part 10 is formed in an inverted U shape with a downward opening, and the sheath member 2 can be inserted. Reinforcing bar hooking parts 11 and 11a extend downward from both lower parts of the sheath insertion part 10. The reinforcing bar hooking parts 11, 11a have curved parts 110, 110a and curved parts 110, 110a. It consists of rising portions 111, 111a extending upward from the top. This rebar hook Since the attachment parts 11 and 11a are bent in opposite directions, they are different from each other. It hangs on reinforcing bar 3 from the side. Also, the rising part of the reinforcing bar hanging part 11a 111a is formed lower than the rising portion 111 of the reinforcing bar hanging portion 11. The spring part 12 is provided on the upper outer side of the sheath insertion part 10, and has an inverse α (alpha) ) character shape.
【０００６】 （作用） 図１及至図３を参照して、本実施例の作用を説明する。 鉄筋の枠組みにシース部材２が数本備えられている。この鉄筋には異形鉄筋が 使用されている。 鉄筋３にシース部材２を取り付けるために、作業員はまずシース取付具１のシ ース嵌入部１０にシース部材２を嵌入させる。次に鉄筋掛着部１１を鉄筋３に掛 ける。そして図２に示すように、鉄筋掛着部１１ａが鉄筋３よりも下方に位置す るまで親指でばね部１２を押し下げ、鉄筋３に掛ける。このようにすることによ って、シース部材２はシース取付具１により鉄筋３に固定される。 ばね部１２が設けられていることにより鉄筋掛着部１１ａを上下に移動するこ とができ、又鉄筋掛着部１１ａの立ち上がり部１１１ａをやや低く立ち上げてい るので、鉄筋３に鉄筋掛着部１１ａを容易に掛けることができる。 又、鉄筋掛着部１１，１１ａは互いに異なる側から鉄筋３に掛かるので、シー ス部材２の伸長方向にシース取付具１が動いても鉄筋３からシース取付具１が容 易に外れてしまうことはない。 更に、シース部材２はスパイラルシースを使用し、鉄筋３は表面に突起をつけ た異形鉄筋が使用されているので、シース取付具１がシース部材２や鉄筋３から 容易に滑り落ちたり、シース部材の固定位置がずれることもない。[0006] (effect) The operation of this embodiment will be explained with reference to FIGS. 1 to 3. Several sheath members 2 are provided on a framework of reinforcing bars. This reinforcing bar has deformed reinforcing bars. It is used. In order to attach the sheath member 2 to the reinforcing bar 3, the worker first attaches the sheath attachment tool 1 to the The sheath member 2 is fitted into the sheath fitting part 10. Next, hang the reinforcing bar hanging part 11 on the reinforcing bar 3. Let's go. As shown in FIG. 2, the reinforcing bar hanging part 11a is located below the reinforcing bar 3. Push down the spring part 12 with your thumb until it hangs on the reinforcing bar 3. By doing this Thus, the sheath member 2 is fixed to the reinforcing bar 3 by the sheath fixture 1. The provision of the spring portion 12 makes it possible to move the reinforcing bar hanging portion 11a up and down. , and the rising part 111a of the reinforcing bar hanging part 11a is raised slightly lower. Therefore, the reinforcing bar hanging portion 11a can be easily hung on the reinforcing bar 3. In addition, since the reinforcing bar hooking parts 11 and 11a hang on the reinforcing bar 3 from different sides, the seams Even if the sheath fitting 1 moves in the direction of extension of the sheath member 2, the sheath fitting 1 will not move from the reinforcing bar 3. It won't come off easily. Furthermore, the sheath member 2 uses a spiral sheath, and the reinforcing bar 3 has protrusions on the surface. Since a deformed reinforcing bar is used, the sheath fitting 1 is not connected to the sheath member 2 or the reinforcing bar 3. The sheath member will not easily slip off or the fixed position of the sheath member will shift.
【０００７】 図４は本考案の第２の実施例を示す斜視図である。 シース嵌入部１０の両下部には、鉄筋嵌着部１３，１３ａが設けられている。 鉄筋嵌着部１３，１３ａは全体としてΩ字状に似た形状をしている。鉄筋嵌着部 １３，１３ａの下部に設けられた開口部１３０，１３０ａは鉄筋３の幅よりも狭 く形成されている。 なお、図４において、図１と同一又は同等箇所には同一符号を付して示してい る。[0007] FIG. 4 is a perspective view showing a second embodiment of the present invention. Reinforcing bar fitting portions 13 and 13a are provided at both lower portions of the sheath fitting portion 10. The reinforcing bar fitting portions 13, 13a have a shape similar to an Ω-shape as a whole. Rebar fitting part The openings 130, 130a provided at the bottom of the reinforcing bars 3 are narrower than the width of the reinforcing bars 3. It is well formed. In addition, in Figure 4, the same or equivalent parts as in Figure 1 are indicated with the same symbols. Ru.
【０００８】 （作用） 鉄筋３にシース２を取り付けるために、作業員はまずシース嵌入部１０にシー ス部材２を嵌入する。次に、鉄筋嵌合部１３，１３ａそれぞれの開口部１３０， １３０ａを鉄筋３の上部から押し付け、鉄筋３に嵌め込む。このようにすること によって、シース部材２は鉄筋３に固定される。 又、本考案は図示の実施例に限定されるものではなく、シース取付具を天地逆 にして使用する等、実用新案登録請求の範囲の記載内において種々の変形が可能 である。[0008] (effect) In order to attach the sheath 2 to the reinforcing bar 3, the worker first inserts the sheath into the sheath insertion part 10. Insert the base member 2. Next, the openings 130 of the reinforcing bar fitting parts 13, 13a, 130a is pressed from above the reinforcing bar 3 and fitted into the reinforcing bar 3. Do it like this As a result, the sheath member 2 is fixed to the reinforcing bar 3. Furthermore, the present invention is not limited to the illustrated embodiment; Various modifications are possible within the scope of the claims for utility model registration, such as using it as a utility model. It is.
