摘要： PURPOSE:To decrease a construction cost, by a method wherein arrangement of bar, in which the upper part of a pile main arrangement of bar forms a PC steel bar constituted in an unbond and the lower part forms a steel bar for reinforced concrete, is installed in an excavated hole, and after concrete is placed therein, the PC steel bar is stretched. CONSTITUTION:The whole of pile arrangement of bar forms a connection main arrangement of bar 4 in which a given upper section L, on which high bending moment is exerted, forms a PC steel bar 1, and a lower section l forms a steel bar 3 for reinforced concrete connected to the PC steel bar 1 by means of a coupler 2. An anchoring metal 5 is attached to the lower end or the connection of the connection main arrangement of bar 4, and arrangement of bar in which the whole surface of the PC steel bar 1 is formed in an unbond 6, is installed in an excavated hole 7. Thereafter, after concrete 14 is placed and cured, given tension is exerted on the PC steel bar 1 from the top of a pile, and the PC steel bar 1 is anchored at 8 to the top part of the pile to exert prestress on concrete 14 at the upper section L.
摘要翻译：目的：为了降低施工成本，通过如下方式，其中，在主组装杆的上部部分形成未粘结的PC钢筋的下部部分形成钢筋混凝土的钢筋的方式，安装在挖掘的孔中，并且在混凝土放置在其中之后，PC钢筋被拉伸。构成：杆的整体排列形成了杆4的连接主体布置，其中施加高弯矩的给定上部L形成PC钢筋1，下部分1形成钢棒3 用于通过联接器2连接到PC钢筋1的钢筋混凝土。锚固金属5连接到杆4的连接主体装置的下端或连接处，并且杆的整个表面 PC钢筋1形成为未粘接6，安装在挖掘孔7中。此后，在混凝土14被放置和固化后，从PC顶部施加张力作用在PC钢筋1上，并且PC钢钢筋1固定在桩的顶部8处，以在上部L对混凝土14施加预应力。

摘要： PURPOSE:To facilitate conveyance and to prevent the generation of noise, by a method wherein plural concrete blocks are piled up in an excavated hole, and after a PC steel material is inserted in the hole of the blocks to strech it, a grout material is poured in the excavated hole. CONSTITUTION:An anchor hole 7, having diameter smaller than that of an excavated hole 6, is excavated in the central base of the excavated hole 6. A PC steel material 8, secured to the inside of the anchor hole 7, is inserted through a PC steel material inserting hole 2 in a concrete block 1 and is sunk in muddy water in the excavated hole 6, and thereafter, the blocks 1 are inserted, in order, into the steel material 8, and piled up. Then, the steel material 8 is stretched to integrally form the blocks 1, and after the blocks are secured by means of a wedge 15, a grout material 12 is poured in the excavated hole 6 through the inserting hole 2.

摘要： PURPOSE:To eliminate the needs for chipping of pile head by a method in which deformed reinforcing bars buried in a pile are connected through a coupler to the top plate of the pile head fixed with one end of PC steel and reinforcing bars for fixing footing are connected to the coupler. CONSTITUTION:A top plate 8 is set on the head of a PRC pile, and one ends of PC steel 5 and deformed reinforcing bars 7 buried in the pile are connected through a coupler 10 to the top plate 8 by using a male screw provided to the ends of the deformed reinforcing bars 7 and a female screw provided to the coupler 10. Deformed reinforcing bars 12 for fixing the footing are fixed with a screw 11a on the upside of the coupler 10. The foundation work can be performed without the needs to remove the concrete of the head of the PRC pile by chipping.
