上次刊登的预应力钢筋混凝土工程(二)主要介绍了用于后张法施工的张拉锚具和预应力钢筋的应用和制作,本节就张拉机具设备和生产工艺再作一介绍。了二、张拉机具设备和生产工艺 (一)张拉机具设备及其校验为了完成预应力筋的张拉工作,必须配备一套张拉机具设备。后张法张拉机具设备主要为千斤顶和高压油泵。无论是 The pre-stressed reinforced concrete project published last time (2) mainly introduced the application and production of tensioned anchorages and pre-stressed reinforcements for post-tensioned construction. This section also introduces the tensioning implements and production processes. Second, tensioning equipment and production processes (a) tensioning equipment and its verification In order to complete the tensioning work of prestressed tendons, must be equipped with a set of tensioning equipment. Post tensioning machine equipment is mainly jacks and high pressure oil pumps. Whether it is
