后张法无黏结施工技术无需预留管道与灌浆,而是将无黏结预应力筋同普通钢筋一样的铺设,在结构模板设计的位置上,然后浇筑混凝土进行养护,待混凝土达到设计要求的强度后,张拉预应力筋并用锚具进行锚固,最后进行封锚。由于其具有施工简便、工期短、造价低、便于更换预应力筋、预应力筋可单独防腐等优点被广泛的应用,现阐述后张法无黏结预应力施工技术分析。
Post-tension method without bonding construction technology without reserving pipes and grouting, but the unbonded prestressed tendons with ordinary steel laying the same, in the structural template design position, and then pouring concrete for conservation until the concrete to meet the design requirements of the strength After the prestressing tendons and anchoring with anchors, and finally anchor closure. Because of its simple construction, short construction period, low cost, easy replacement of prestressed tendons, prestressed tendons can be a single anti-corrosion and other advantages are widely used, are described post-tension method unbonded prestressed construction technology analysis.
