SHEARING REINFORCED PC PILE
To provide a shearing reinforced PC pile that is superior in productivity, and that has a simple structure and high shearing resistance.SOLUTION: A shearing reinforced PC pile 1 includes a cylindrical concrete body 2, a plurality of PC steel materials 3, 3... embedded in the concrete body 2 at regular intervals circumferentially, and a shearing reinforced steel pipe 4 constraining the circumference of the concrete body 2. The shearing reinforced steel pipe 4 is made of thin steel plates. By means of prestress introduced by the PC steel materials 3, 3..., the shearing reinforced PC pile 1 resists bending stress acting on the pile, and resists shearing stress acting on the pile by the searing reinforcing steel pipe 4.SELECTED DRAWING: Figure 1
【課題】生産性に優れ、且つ、簡易な構造で高いせん断耐力を有するせん断補強PC杭の提供。【解決手段】せん断補強PC杭1は、筒状のコンクリート体2と、周方向に間隔を置いてコンクリート体2に埋設された複数のPC鋼材3,3…と、コンクリート体2の外周を拘束するせん断補強鋼管4とを備え、せん断補強鋼管4は、薄肉鋼板からなる。そして、PC鋼材3,3…によってプレストレスが導入され、杭に作用する曲げ応力に対抗するとともに、せん断補強鋼管4によって杭に作用するせん断応力に対抗するようになっている。【選択図】図1
