Description

Technical Field

[0001] The utility model relates to the technical field of building integrated photovoltaic (BIPV), and discloses a photovoltaic curtain wall connection structure and a photovoltaic curtain wall. Background Art

[0002] BIPV (Building Integrated Photovoltaic) is a photovoltaic power generation system that is designed, constructed, and installed simultaneously with a new building and integrated with the building. It is an essential part of the building, playing the functions of building materials (such as wind protection, rain protection, heat insulation, etc.) and power generation, making the building a green building. In the context of global carbon reduction, the application demand for photovoltaic curtain walls is increasing. Photovoltaic curtain walls are usually made of aluminum alloy structures and are installed by hanging on-site, which is becoming a trend.

[0003] The structures of photovoltaic curtain walls are mainly divided into two categories: exposed frame photovoltaic curtain walls and hidden frame photovoltaic curtain walls. An exposed frame photovoltaic curtain wall is a photovoltaic curtain wall with metal frame members exposed on the outer surface, and the metal frame of a hidden frame photovoltaic curtain wall is hidden behind the glass and cannot be seen from the outside. Hidden frame photovoltaic curtain walls can be further divided into fully hidden frame photovoltaic curtain walls and semi-hidden frame photovoltaic curtain walls. A semi-hidden frame photovoltaic curtain wall can be horizontal exposed and vertical hidden or vertical exposed and horizontal hidden.

[0004] Chinese patent document CN220301586U (202321612406.6) discloses an assembled photovoltaic glass curtain wall system. By designing two symmetrical sub-frames as adapters to install and fix the ends of adjacent two photovoltaic glass panels, it can be applicable to both exposed frame glass curtain walls and hidden frame glass curtain walls. However, in the above photovoltaic glass curtain wall system, the photovoltaic glass panels are only fixed from the vertical sides, with poor stability and inconvenient positioning and installation.
