1. This application is equipped with two sets of positioning crossbar assemblies and positioning vertical pipes, which can quickly realize accurate positioning. The crossbar assembly can quickly realize the rapid positioning of two adjacent sound barrier H-shaped steel column embedded parts columns without the need for The traditional total station positioning mark can also realize the positioning between adjacent columns on the same embedded part, and does not need the traditional positioning marking method. In addition, the positioning vertical pipe is directly a threaded structural part, which can be realized most accurately The optimal positioning of the column avoids the error caused by the positioning of the mark, which makes it difficult to install;

2. It is equipped with the first cross bar and the second cross bar adjusted by the socket tube, as well as the adjustment rod assembly, and is equipped with fixed bolts, which can meet different installation requirements, and then be suitable for different constructions, realize turnover and utilization, and reduce waste;
