1, stone curtain wall dry hanging-post-planting and built-in parts
The post-implantation embedded parts, steel plates and corner codes have been welded in the factory, and the whole installation can be completed after hot tin plating.
2, stone curtain wall dry hanging pin type
It is the earliest dry hanging method, which originated in the early 1980 s and was introduced from abroad. It is the reference of all dry hanging methods. Its main stress point is on the pin, which is concentrated in stress, easy to break, laborious and expensive to operate, and has been gradually replaced by other methods.

The shape of the pendant,
The strength of the pendant has been destroyed when it is made and molded, and it is also easy to be destroyed when it is installed. Also need a lot of glue, high cost, high technical requirements for installation workers. Relatively speaking, this dry hanging method of stone curtain wall is not commonly used now. 4, stone curtain wall dry hanging type
Commonly known as welded joints, this dry hanging method should be regarded as a common crime in decoration construction at present.
Its force transmission is simple, which can effectively reduce the stone crushing rate. When welding, ensure that the weld is full, otherwise it will cause oxidation corrosion and shedding. If it is serious, the embroidered water will penetrate into the stone along the groove, and the whole curtain wall surface will be like a skin disease, which will affect the overall environmental protection and beauty.

This kind of stone curtain wall is imported from Germany. The method is to punch holes in the back of the stone, connect the keel with money bolts, and then fix it with cutting anchor bolts.

6, stone curtain wall dry hanging-back hanging type
Hanging on the back, also called hiding hanging, is the mainstream dry hanging method today. The pendant is made of silicon-magnesium alloy, which has been patented in China, the United States, Britain and Taiwan Province Province. Its construction method is that the back of each board is fixed, and there is no connection between boards, so there will be no uncertainty caused by board interconnection. Phase Si-Mg alloy is light in weight and has the characteristics of corrosion resistance, high temperature resistance and aging resistance. It is especially suitable for high-rise buildings and earthquake-resistant buildings.
