| description | The invention provides a prestress construction method and device. The method comprises the steps that a flexible bag is pre-buried in the design position of a prestress steel beam; the flexible bag is filled with a fluid medium, so that the flexible bag expands, deforms and is supported in the concrete; after the concrete is solidified and meets the expected requirement, the fluid medium in the flexible bag is discharged, so that the flexible bag is separated from the concrete; the flexible bag is taken out, and a prestress strand penetrating hole channel is formed; and a prestressed steel beam is placed in the prestressed beam penetrating hole channel, anchored and tensioned. According to the invention, the gas (liquid) bag is adopted to realize post-tensioning method post-strand pulling prestressed duct pore-forming.
本发明提供了一种预应力施工方法及装置，所述方法包括：将柔性囊预埋在预应力钢束的设计位置；向所述柔性囊内充入流体介质，以使所述柔性囊膨胀变形并支撑在混凝土内部；当混凝土凝固并达到预期要求后，排出所述柔性囊内的流体介质，以使所述柔性囊与混凝土脱离；取出所述柔性囊，形成预应力穿束孔道；以及将预应力钢束放置于所述预应力穿束孔道内，锚固并张拉。本发明采用气(液)囊实现后张法后穿束预应力孔道成 |
