Prestress tension construction process
The invention discloses a prestress tensioning construction technology, and belongs to the technical field of constructional engineering. The process comprises the following steps: carrying out safety check on a tensioning environment of two sections of steel strand bundles; after it is determined that the tensioning environment is safe, tensioning tools are installed at the tensioning ends of the two connecting anchorage devices of the two steel strand bundles; sequentially and synchronously pre-tightening the single steel strands corresponding to the connecting anchorage device hole sites in the two sections of steel strand bundles; the two steel strand bundles are tensioned in a whole bundle at the same time, that is, after it is determined that the tensioning environment is safe, single steel strand synchronous pre-tightening is conducted on the tensioning ends of the single steel strands corresponding to the anchorage device connecting hole positions in the two steel strand bundles, so that each steel strand is evenly stressed, and the tensioning effect is good. After a single steel strand in the two sections of steel strands is pre-tightened, the whole strand is tensioned, so that the situation that one section of steel strand is fixed and the other section of steel strand is tensioned firstly is avoided, the two sections of steel strands are stressed differently, and breakage of the steel strands is avoided.
本申请公开了一种预应力张拉施工工艺，属于建筑工程技术领域。该工艺包括对两段钢绞线束的张拉环境进行安全检查；在确定所述张拉环境安全后，在两段钢绞线束的两个连接锚具的张拉端安装张拉工具；对两段所述钢绞线束中的所述连接锚具孔位对应的单根钢绞线依次进行同步预紧；对两段所述钢绞线束同时进行整束张拉，也就是说，本申请中在确定张拉环境安全后，对两段刚绞线束中连接锚具孔位对应的单根钢绞线的张拉端将进行单根同步预紧，使每根钢绞线都受力均匀，在将两段钢绞线中的单根钢绞线预紧完成后，再进行整束张拉，避免一段钢绞线束固定，先张拉另一段钢绞线束，使两段钢绞线束受力不同，避免了钢绞线的断裂。
