する躯体であればよい。In FIG. 1, 1 is a concrete column, and a slab formwork 2 is assembled between the column heads 1a. In addition, the concrete column 1 may be a wall body, and in short, it may be a frame body that supports a slab.
続いて、上記スラブ型枠２内に、例えばポリエチレンシ
ース等のシース３を配置する。この場合、シース３は、
図示のように、スラブ中間部分ではスラブの下端近くに
配置し、また、コンクリート柱１に近い部分ではスラブ
の上端近くに配置して、以上のようにシース３の配置が
完了したら、第２図に示すように、上記スラブ型枠２内
にコンクリートＣを打設する。Subsequently, a sheath 3 such as a polyethylene sheath is placed within the slab formwork 2. In this case, the sheath 3 is
As shown in the figure, the sheath 3 is placed near the bottom end of the slab in the middle part of the slab, and the sheath 3 is placed near the top end of the slab in the part near the concrete column 1. As shown in the figure, concrete C is poured into the slab formwork 2.
コンクリートＣが硬化して所定の強度に達したら、第３
図に示すように、上記シース３内に炭素繊維線４を通す
。When concrete C hardens and reaches the specified strength, the third
As shown in the figure, a carbon fiber wire 4 is passed through the sheath 3.
この炭素繊維＃ｊＩ４は、例えば石油ピッチを原料とし
、引張強度が約２５０−７００ ｋｇ／Ｃｍ２のもので
あるが、これに限定するものではなく、現在新素材とし
て一般に開発されている炭素繊維であればいずれでもよ
く、その形態も、細い炭素繊維線材を多数束にしてもち
いたり、より線としたり、又は棒状であってもよい。This carbon fiber #jI4 is made from petroleum pitch, for example, and has a tensile strength of approximately 250-700 kg/Cm2, but is not limited to this, and may be a carbon fiber that is currently being generally developed as a new material. Any type of carbon fiber wire may be used, and the shape thereof may be a bundle of many thin carbon fiber wires, a stranded wire, or a rod shape.
続いて、上記シース３内に炭素繊維線４を挿通させて、
その両ｊＩｇを適宜ジヤツキ（図示せず）により、第４
図に示すように、矢印方向に引張ってコンクリートＣに
プレストレスを与え、その両端部をプレート等の適宜定
着手段によりコンクリートＣに定着させる。この状態で
、スラブの中央部には懸垂力が生じてスラブの曲げ応力
を低減せしめることができる。Next, the carbon fiber wire 4 is inserted into the sheath 3,
Both jIg are suitably adjusted (not shown) to the fourth
As shown in the figure, prestress is applied to the concrete C by pulling in the direction of the arrow, and both ends thereof are fixed to the concrete C by appropriate fixing means such as plates. In this state, a suspension force is generated in the central portion of the slab, and the bending stress of the slab can be reduced.
尚、上記炭素繊維＠４の上記シース３内への挿通は、シ
ース３をスラブ型枠２内に配置する前から、シース３内
に挿設させておいてもよい。Note that the carbon fiber @4 may be inserted into the sheath 3 before the sheath 3 is placed in the slab formwork 2.
また、上記炭素繊維＃Ｘ４がコンクリートへ十分な強度
