摘　　要：根据万向节中心与电视塔塔柱中心保持同心性的基本原理,虽然主体塔柱有一定的倾角,其万向节中心设置的标志杆亦能与塔柱中心保持同心且垂直.实践证明,在直立散拼装方式的构件空间定位中,应用万向节确定定位目标快捷准确,保证了施工准确度,提高了工作效率.According to the basie principle of the gimbal keeping the same center with the pier of television tower, although the pier has some oblique angles, the sign role setup in the gimbal center keeps the same center with the pier and be perpendicular. The practices proved that the orientation of upright members was rapid and accurate by using gimbals, the construction precision was ensured and the work efficiencv increased.
