Large-span curve prestressed beam and accurate and rapid construction method thereof
The invention provides a large-span curve prestressed beam and an accurate and rapid construction method thereof.The large-span curve prestressed beam comprises a steel bar body and a controller, the outer side of the steel bar body is sleeved with a formwork, a tensioning pipe is fixedly arranged in the steel bar body, a steel strand is arranged in the tensioning pipe, and a bleeding pipe is arranged at the top of the tensioning pipe; the end part of the bleeding pipe is connected with a transparent pipe, the outer side of the transparent pipe is provided with a detection device for detecting whether slurry reaches the interior of the transparent pipe, the top end of the transparent pipe is only provided with an extension pipe, and a plug and a driving part for driving the plug to abut against or be far away from the end part of the extension pipe to close or open the extension pipe are erected above the extension pipe; the driving part and the detection device are both connected with the controller; the serous fluid waste can be reduced, the bleeding pipe does not need to be closed manually, and an operator can be away from the bleeding pipe and is prevented from being polluted.
本发明提供一种大跨曲线预应力梁及其精准快速施工方法，大跨曲线预应力梁，包括钢筋主体及控制器，钢筋主体的外侧套装有模板，钢筋主体的内部固定设置有张拉管，张拉管的内部设置有钢绞线，张拉管的顶部设置有泌水管，泌水管的端部连接有透明管，透明管的外侧设置有用于检测浆液是否到达其内部的检测装置，透明管的顶端设只有延长管，延长管的上方架设有堵头及驱动堵头抵紧或远离延长管端部以封闭或开启延长管的驱动部件，驱动部件及检测装置均与控制器连接；本发明能够减少浆液浪费，无需人工对泌水管进行封闭，操作人员可以远离泌水管避免污染操作人员。
