Spherical belt spherical crown prefabricating, assembling and positioning method
The invention discloses a method for prefabricating, assembling and positioning a spherical cap of a ball belt, which comprises the following steps of: selecting two upper tool reference points of the ball belt with a connecting line passing through a central reference point of a dome assembling site at an upper opening of the dome ball belt, and arranging two dome site peripheral common reference points at the periphery of the dome ball belt as check points; a ball belt supporting base of the dome outer ring and a spherical crown supporting base of the dome inner ring are manufactured; setting up a ball belt plate mounting support column, and setting an adjustable back shore for adjusting the radius of the dome plate; hoisting a ball belt plate; checking an upper opening of the ball belt plate, calculating radius deviation, and adjusting the position of the ball belt plate; carrying out ball belt plate welding to form a dome ball belt; measuring the coordinate positions of the tool datum points on the two ball belts; hoisting the spherical crown plate; a total station is erected on the tool datum point on the ball belt, and the coordinate position of the common datum point on the periphery of the dome site is checked; checking and measuring the upper opening of the spherical crown plate to obtain radius deviation; and welding to form the spherical crown. Measurement and positioning work can be conveniently carried out, the measurement precision can be guaranteed, and the construction efficiency can be improved.
本发明公开了一种球带球冠预制拼装定位方法，在穹顶球带上口选择连线经过穹顶拼装场地中心基准点的两个球带上工装基准点，在穹顶球带外围设置两个穹顶场地外围公用基准点作为检查点；制作穹顶外圈的球带支撑基座和穹顶内圈的球冠支撑基座；搭设球带板安装支撑柱，设置调整穹顶板半径的可调顶撑；吊装球带板；对球带板上口检查计算半径偏差，调整球带板的位置；进行球带板焊接，形成穹顶球带；测量两个球带上工装基准点的坐标位置；吊装球冠板；球带上工装基准点架设全站仪，检查穹顶场地外围公用基准点的坐标位置；对球冠板上口进行检查测量，半径偏差；焊接形成球冠。本发明便于开展测量定位工作，有利于测量精度的保证、施工效率的提高。
