Prestress multi-stroke tensioning automatic control method
The invention discloses an automatic control method for prestress multi-stroke tensioning. The prestress multi-stroke tensioning automatic control method comprises the following steps that an anchor clamp, a limiting plate and a jack are installed at preset tensioning positions; the jack is connected with the tensioning system; inputting tensioning parameters in a tensioning system, setting the maximum stroke of a jack and setting a reverse jacking execution value; the steel strand is pre-tightened; the steel strand is automatically tensioned; and the automatic tensioning operation is completed and a report is generated. The prestress multi-stroke tensioning automatic control method is high in applicability, the extension amount of the jack can be automatically recognized, the jacking opportunity can be automatically judged, the jacking times are not limited, and the extension amount of the steel strand is more uniform.
本发明公开了一种预应力多行程张拉自动控制方法。所述预应力多行程张拉自动控制方法包括以下步骤：将锚夹具、限位板及千斤顶安装到预定张拉位置；将千斤顶与张拉系统进行连接；在张拉系统中输入张拉参数、设置千斤顶最大行程以及设置倒顶执行值；对钢绞线进行预紧；对钢绞线进行自动张拉；自动张拉操作完成并生成报表。本发明提供一种预应力多行程张拉自动控制方法，适用性强，能自动识别千斤顶伸出量，能自动判断倒顶时机且倒顶次数不受限制，钢绞线伸长量更为均匀。
