[0002] As an effective wall energy-saving insulation system, the thin plaster external wall external thermal insulation system has been developed and applied in China for nearly 20 years. With the deepening of the "double carbon" goal and task, the market application of the thin plaster external wall external thermal insulation system will continue to expand. At the same time, in order to ensure the fire safety design of the system, the application proportion of A-grade non-combustible insulation materials in the insulation material is increasing year by year.

[0003] The most common A-grade non-combustible insulation materials in the thin plaster external wall external thermal insulation system are rock wool, thermosetting composite polystyrene foam insulation board (G type), foamed cement board, and expanded perlite board. The bulk density of these materials is generally large, at least more than 100 kg / m3. Compared with the commonly used B1-grade insulation material EPS board (the bulk density is generally not more than 20 kg / m3), the high self-weight of these materials poses a greater structural safety risk to the wall materials and systems that mainly rely on adhesion.

The bracket itself is prone to rust in the later use, and the insulation may fail; the weight of the galvanized angle steel or bent galvanized steel plate is large, and the installation process is difficult to operate.
