Steel strand prestress tensioning equipment
The invention relates to steel strand prestress tensioning equipment. The steel strand prestress tensioning equipment comprises a jack support, the jack support is provided with at least two tensioning jacks which are each used for tensioning a steel strand, and each tensioning jack is of a hollow structure. The steel strand prestress tensioning equipment further comprises tensioning force detection structures used for detecting the tensioning forces of the corresponding tensioning jacks. Each steel strand is tensioned by the corresponding tensioning jack, each tensioning jack only tensions one steel strand, and it is guaranteed that each steel strand can reach the corresponding designed tensioning value. In addition, each steel strand corresponds to one tensioning jack, and therefore therequirement for the maximum tensioning force of all the tensioning jacks is lowered, the manufacturing cost of the tensioning jacks is very low, and the manufacturing cost of the whole double-mode self-calibration tensioning equipment is greatly reduced.
本发明涉及一种钢绞线预应力张拉设备，包括千斤顶支架，千斤顶支架上设置有至少两个使用时分别张拉一根钢绞线的所述张拉千斤顶，各张拉千斤顶均为空心结构，钢绞线预应力张拉设备还包括用于检测对应张拉千斤顶张拉力的张拉力检测结构。各钢绞线分别由各自对应的张拉千斤顶张拉，每个张拉千斤顶仅对一根钢绞线进行张拉，可以保证每根钢绞线均能到达相应的设计张拉值，此外，每根钢绞线对应一个张拉千斤顶，因此降低了对各张力千斤顶的最大张拉力需求，张拉千斤顶的制造成本非常低，因此大大降低了整个双模自校准张拉设备的制造成本。
