Description

Technical Field

[0001] The present invention relates to the technical field of building curtain walls, in particular to a green energy-saving curtain wall and a construction and reconstruction method thereof. Background Art

[0002] With the rapid development of building energy conservation and green technology, the function of curtain wall as an important part of building envelope has shifted from simple aesthetics and lighting to energy conservation, power generation and intelligent control integration.

[0003] Traditional curtain walls mostly use a single photovoltaic module or a fixed ventilation structure, and the position of the photovoltaic modules of conventional photovoltaic curtain walls is fixed and cannot be dynamically adjusted according to the light angle, resulting in limited power generation efficiency; and the lack of a multi-level power generation structure makes it difficult to maximize the use of light energy. At the same time, existing ventilation structures mostly rely on mechanical switches or fixed ventilation holes, and cannot adjust the air volume in real time. They are easily affected by the external environment and it is difficult to balance indoor and outdoor airflow and energy-saving needs. Traditional curtain wall connection structures are mostly rigidly fixed, which is difficult to adapt to the installation angles and splicing requirements of different building exterior walls, resulting in low construction efficiency and difficult subsequent maintenance. In addition, the glass layer fixing method is single, and the clamping components lack flexible adjustment capabilities. The glass is easily offset due to thermal expansion and contraction or vibration, affecting the sealing and safety. In view of this, there may already be technical means to solve the above problems in the existing technology, but this case wants to provide an alternative or replacement technical solution.
