Prestressed reinforcement tensioning construction method suitable for limited space
The invention relates to a prestressed reinforcement tensioning construction method suitable for a limited space. The prestressed reinforcement tensioning construction method comprises the following steps that a working anchorage device is installed; mounting a working clamping piece; mounting a professional limiting plate; mounting a common limiting plate; installing a jack; installing a tool anchorage device; installing a tool clamping piece; performing tensioning operation; and sealing the anchor. According to the method, high-quality tensioning can be achieved for the prestressed reinforcement in the limited space, small-space prestressed tensioning construction of the tensioning notch of the cast-in-place box girder can be conveniently achieved by utilizing the professional limiting plate and cooperating with an exclusive tensioning technology, the construction efficiency is improved, the limited space operation time is shortened, meanwhile, the professional limiting plate can be repeatedly used after tensioning is completed, and the construction cost is reduced. Resource waste is reduced, and construction cost is saved.
本发明是一种适用于受限空间的预应力钢筋张拉施工方法，包括以下步骤：安装工作锚具；安装工作夹片；安装专业限位板；安装普通限位板；安装千斤顶；安装工具锚具；安装工具夹片；张拉作业；封锚作业。本发明能够针对受限空间预应力钢筋实现高品质量张拉，利用专业限位板，并配合专属的张拉工艺可方便地实现现浇箱梁张拉槽口小空间预应力张拉施工，提升施工效率，减少受限空间作业时间，同时张拉完成后专业限位板还能重复使用，降低资源浪费，节约施工成本。
