REINFORCEMENT NET FOR CAST-IN-PLACE CONCRETE PILE AND CAST-IN-PLACE CONCRETE PILE
To provide a cast-in-place concrete pile with a uniform section and a reinforcement net constructible by preventing breakage or swelling of a permeable net by impact or lateral pressure in concrete placing.SOLUTION: A reinforcement net is constituted of a permeable net 9 covering the outer periphery of a cage 2 and a plurality of reinforcement ribs 16 formed at the permeable net 9. The reinforcement rib 16 is formed of a pleat part 14 and a reinforcement tape 10 attached on the pleat part 14. The pleat part 14 is formed by folding a part of the permeable net 9 in the circumferential direction of the cage 2. The reinforcement tape 10 is folded into a U-shape along a cross-sectional shape of the pleat part 14, and is sewn to the permeable net 9 together with the pleat part 14 with sewing yarn 12.SELECTED DRAWING: Figure 5
【課題】コンクリート打設時の衝撃や側圧等による透水性ネットの破断や膨出等を防止して、均一断面の場所打ちコンクリート杭を施工可能なコンクリート杭及び補強用ネットを提供する。【解決手段】鉄筋かご2の外周を覆う透水性ネット9と透水性ネット9に形成された複数の補強リブ16とから構成する。補強リブ16はヒダ部14とヒダ部14の上に取り付けられた補強テープ10とから形成する。ヒダ部14は透水性ネット9の一部を鉄筋かご2の周方向に折り込むことにより形成する。補強テープ10はヒダ部14の断面形状に沿ってＵ形状に折り込み、かつヒダ部14と共に透水性ネット9に縫い糸12によって縫い付ける。【選択図】図5
