摘要： In the present invention, testing is performed by injecting grout (G) into a full-scale specimen comprising a cable that is fabricated at a place other than a construction site. The cable has a sheath made of a transparent material and has the same three-dimensional configuration as that of an internal cable (2°) at the construction site. Alternatively, grout (G) is injected into a partial specimen comprising a lengthwise part of the cable where an air trap is likely to occur. The testing is performed under a plurality of different testing conditions. The best grouting conditions are selected from testing results and applied to grouting actually carried out at the construction site. With the conventional method of grouting an internal cable of a post-tensioned prestressed-concrete structure, it is difficult to check at the construction site whether or not the internal cable is filled with grout without an air trap remaining therein because the cable is laid in concrete and hence the sheath (3′) is hidden by the concrete. It is possible according to the present invention to provide a post-tensioned prestressed-concrete structure free from an air trap (V) in the sheath and hence free from the danger of corrosion or breaking of prestressing steel used in the cable.
摘要翻译：在本发明中，通过将灌浆（G）注入到包括在施工现场以外的地方制造的电缆的全尺寸试样来进行试验。电缆具有由透明材料制成的护套，并且具有与施工现场的内部电缆（2°）相同的三维构造。或者，将浆料（G）注入包括可能发生空气阱的电缆的纵向部分的部分样品。测试在多个不同的测试条件下进行。最佳灌浆条件选自试验结果，适用于施工现场实际进行的灌浆。采用传统的注浆后预应力混凝土结构内部电缆的方法，难以在施工现场检查内部电缆是否填充有水泥浆，而不会留下空气阱，因为电缆铺设在混凝土，因此护套（3'）被混凝土隐藏。根据本发明，可以提供一种在护套中没有空气阱（V）的后张紧的预应力混凝土结构，因此没有在电缆中使用的预应力钢的腐蚀或断裂的危险。

摘要： A PC strand is formed by twisting peripheral wires made of deformed PC steel wires around a core, and allowing rust inhibitive material of thermoplastic resin to permeate into voids defined among the core and peripheral wires by use of an extruder. Since at least one of the core and peripheral wires is made of a deformed PC steel wire having an uneven outer surface, the thermoplastic resin can smoothly permeate deep into the inside of the PC strand.
摘要翻译：通过将由变形的PC钢丝制成的外围线缠绕在芯上，并且使热塑性树脂的防锈材料通过挤出机渗透到芯和外围丝之间的空隙中而形成PC绞合线。由于芯线和外围线中的至少一个由具有不均匀外表面的变形PC钢丝制成，所以热塑性树脂可以平滑地渗透到PC股的内部。

摘要： A reinforcement binding machine using a steel wire comprises a means for feeding the steel wire into a binding station for binding reinforcements together, a guide means provided with a guide path for guiding the steel wire fed into the binding station along a curve encircling the reinforcements and defining the binding station, a means for twisting the steel wire looped by the guide path and defining a slot through which the steel wire fed into the binding station is capable of passing, and a means for rotating the twisting means about the axis crossing the axis of the loop formed from the steel wire so as to twist the steel wire, the twisting means being provided with a pair of pins opposed to each other through the slot and adapted to be moved relatively in the axial direction with respect to the loop, and a means for normally biasing at least one of the pins toward the other one of the pins such that the end faces of the pins are abutted against each other within the binding station.
