Spatial positioning and measuring method for suspension bridge cable clamp
The invention provides a spatial positioning and measuring method for a suspension bridge cable clamp, which comprises the following specific steps of: 1, calculating cable clamp construction lofting data, and performing field data actual measurement; and 2, mounting the cable clamp according to the lofting data and the measured data in the step 1, measuring the transverse inclination angle of the cable clamp through a vernier universal angle ruler and a horizontal ruler, determining and adjusting the angle of a lug plate of the cable clamp, and finally mounting the cable clamp. According to the method, retreating is carried out for several times, lofting is carried out in a vertical plane, and after a main cable is preliminarily separated, cable clamps are directly and symmetrically installed from a main tower to the midspan through a truck crane or a tower crane. After the main cable transversely moves and is pulled open and before the sling is installed, the vernier universal bevel protractor and the leveling instrument are adopted to measure the transverse dip angle of the sling clamp according to a monitoring instruction, the angle of the sling clamp lug plate is finally adjusted, and final installation of the sling clamp is conducted. Construction is safe and reliable, the installation efficiency is high, the bridge site installation construction period of the cable clamp is greatly shortened, the space installation positioning precision of the cable clamp is improved, and practicability is high.
本发明提供一种悬索桥索夹的空间定位及测量方法，具体步骤为：步骤一，索夹施工放样数据计算，并进行现场数据实测；步骤二，根据步骤一中的放样数据和实测数据进行索夹安装，通过游标万能角度尺和水平尺测量索夹横向倾角，确定调整索夹的耳板角度，进行索夹的终安装。本发明采取退后分次进行，在铅垂面内放样，主缆初步分开后利用汽车吊或塔吊从主塔向跨中直接进行对称安装索夹。待主缆横移拉开后、吊索安装前，依据监控指令采用游标万能角度尺和水平尺测量索夹横向倾角最终调整索夹耳板角度，进行索夹的终安装。本发明施工安全可靠，安装工效高，大大缩短了索夹的桥位安装施工工期，提高了索夹空间安装定位精度，实用性强。
