When the GRC line is installed on the external wall, 8~10 ordinary expansion bolts are generally installed on the external wall according to the installation drawings provided by the manufacturer, and then the bid winning 6 steel bars are welded with the embedded steel bars on the line, or the decorative protrusions and window ceiling flowers are directly fixed on the wall with expansion bolts. The above installation methods generally adopt spot welding during construction, and the welding length does not meet the requirements. After the expansion bolt is installed on the wall, it is easy to hit the brick joint, and does not work, which does not meet the requirements of the construction specification, bringing danger to the installation of GRC line.

The installation method of non bearing GRC Roman column is the same as pouring concrete from the upper opening after installation. The difference is that load-bearing GRC Roman columns should be installed first and then covered, otherwise concrete cannot be poured, while non load-bearing GRC Roman columns can be decorated with buildings first and then GRC Roman columns.

According to the thickness of GRC material and different surface treatment methods, good sound insulation and absorption effects can be achieved. In addition, its light weight and high strength make it more resistant to earthquake impact than other materials. Hainan Sculpture _ Hainan GRC component _ Hainan EPS
