Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, and specifically relates to a connecting joint heat preservation structure suitable for super low energy consumption building curtain wall. BACKGROUND

[0002] With the increasing concern about energy consumption worldwide, super low energy consumption buildings have become an important development direction of the building industry. Super low energy consumption buildings require curtain wall systems to have excellent heat preservation, heat insulation, air tightness and water tightness to ensure the energy efficiency and comfort of the building. However, traditional curtain walls only focus on the appearance of the facade or the mechanical properties such as seismic resistance, and the connecting joints often have problems such as insufficient heat preservation performance, poor air tightness, and unclear fireproof performance, making it difficult to meet the requirements of super low energy consumption buildings.

[0003] The existing patent CN 215802503 U outlines a glass curtain wall and heat preservation system connecting structure suitable for passive low energy consumption buildings. However, this patent only uses waterproof vapor permeable membrane and waterproof vapor barrier membrane as air tightness materials, but the membrane material may leak due to aging, construction defects or wind pressure, reducing the air tightness of the building. In extreme fire conditions, ordinary insulation materials may burn or release toxic gases, and there is no fireproof separation layer, which poses a safety hazard. The need for staggered bonding of the bottom layer of insulation, additional insulation layer, installation of metal edge plates and closure of gaps makes the construction process complicated and may increase the risk of human error.
