AI Technical Summary
Technical Problem
[0004]上述中的相关技术方案存在以下缺陷：为减少风阻或提升结构强度，安装在不同高度的塔桥的混凝土构件横截面面积不同，因此各个混凝土构件的形状不同，将待安装的混凝土构件堆叠在已安装好的混凝土构件上时，难以观察吊装混凝土构件的预定位置，易使吊装的混凝土构件位置偏移，造成混凝土构件的空腔不对齐，影响施工质量
Benefits of technology
1.通过在架体上设置固定机构，施工人员能够将筒体插入已安装的混凝土构件中，通过固定机构将筒体固定在混凝土构件中，通过在筒体上设置多个检测机构，使检测机构分别位于筒体的上侧和下侧，施工人员将架体固定在已安装的混凝土构件上后，位于下侧的检测机构能够检测筒体到混凝土构件的空腔内壁的间距，从而模拟出已安装的混凝土构件的空腔形状，当施工人员吊装另一个混凝土构件时，筒体的上端插入吊装的混凝土构件中，位于上侧的检测机构能够检测筒体到混凝土构件内壁的间距，通过对比竖直位置上的两个检测机构的检测数据，施工人员能够得知需要将吊装的混凝土构件移动至何种方向和长度，进而提升吊装混凝土构件的精准性；
