根据预应力钢材的不同锚固方式,国外预应力方法主要有表1所列几种。各种预应力方法中张拉力最大的锚具配置见表2。一、楔式锚固方式1.弗莱辛奈法锚具如图1所示,采用锚环和锚塞锚固预应力钢材。锚塞有砂浆制的和钢制的。虽然一般不使用联结器,但有时也用图2所示 According to different anchoring methods of prestressed steel, foreign prestressing methods are mainly listed in Table 1. See Table 2 for the configuration of anchors with the greatest tension in various prestressing methods. 1. Wedge anchoring method 1. Frying Naifa anchorage As shown in Figure 1, the prestressed steel is anchored with anchor rings and anchor plugs. Anchors are made of mortar and steel. Although generally not using a coupling, it is sometimes used as shown in Figure 2.
