Prefabricated segmental beam axis measuring and positioning device and measuring method
The invention relates to a prefabricated segmental beam axis measuring and positioning device and a measuring method, and the device comprises a pre-embedded assembly which is used for being pre-embedded on a prefabricated segmental beam in the transverse bridge direction, and the two ends of the pre-embedded assembly are located on the two sides of the axis of the prefabricated segmental beam respectively; a connecting piece; scales are arranged on the transverse rod; the cross rod is parallel to the embedded assembly and is detachably connected with the embedded assembly through a connecting piece; and the positioning indicating piece is movably arranged on the cross rod, indicates the scale value of the positioning indicating piece and is used for providing a mark point of the total station. In the factory-leaving section, the transverse rod and the positioning indicating piece are installed on the pre-embedded assembly through the connecting piece, and then factory-leaving axis point scales corresponding to the axis points of the prefabricated segmental beam are obtained through the total station; when the prefabricated segmental beam is installed on the bridge pier, only the positioning indicating piece needs to be moved to the factory axis point scale, so that when the prefabricated segmental beam is erected, the axis point can be obtained without measurement, the influence of disappearance of the marking point is avoided, and the reflector plate is prevented from being supported.
本申请涉及一种预制节段梁轴线测量定位装置及测量方法，其包括：预埋组件，其用于沿横桥向预埋在预制节段梁上，并且其两端分别位于预制节段梁轴线的两侧；连接件；横杆，其上设有刻度；横杆与预埋组件平行，以及通过连接件与预埋组件可拆连接；定位指示件，其移动设置在横杆上，并指示出其所在刻度值，以及用于提供全站仪的标记点。在出厂节段，将横杆和定位指示件通过连接件安装在预埋组件上，然后通过全站仪得出预制节段梁的轴线点所对应的出厂轴线点刻度；在桥墩安装预制节段梁时，只需要将定位指示件移动至出厂轴线点刻度即可，从而使得在架设预制节段梁时，无需测量就可得出轴线点，不受标记点消失的影响，以及避免进行扶持反射片。
