[0002] The welding-free open stone curtain wall structure is a modern building facade device, mainly used to improve the aesthetics and functionality of buildings. The structure connects stone panels in a welding-free manner, usually using mechanical fixation or other connection methods.

The stone curtain wall system has high connection strength and stability, good heat insulation performance, sound insulation performance and air tightness, convenient connection and installation, easy construction, and can be well applied to passive double zero energy consumption buildings to meet the heat insulation, sound insulation and air tightness requirements of passive double zero energy consumption buildings.

Long-term accumulation of heat may cause thermal expansion of the curtain wall material, which may cause deformation or cracking of the curtain wall, and on the other hand, due to temperature difference, water vapor may condense at the joint between the thermal insulation layer and the curtain wall, which may cause mold, corrosion and aging of the internal thermal insulation material.
