A light and heat collection type energy-saving building curtain wall

Abstract

The invention discloses a light-heat collection type energy-saving building curtain wall, which comprises a hollow keel bracket fixedly installed on the outside of the building exterior wall, more than one installation cavity is equidistantly opened on the hollow keel bracket, and the outer ends of the bottom surface of the installation cavity are respectively opened A groove, an elastic connecting piece is put into the groove, and the other end of the elastic connecting piece is connected to a sealing frame, the outer side of the sealing frame is a glass curtain wall panel, and the inner side of the sealing frame is a photovoltaic power generation panel, which is sealed by the entire sealing frame Installation cavity: The building curtain wall structure of the present invention closes the installation cavity at night and uses it as an outer wall for heat preservation. During the day, the sealing frame can be opened to expose the light-emitting board power generation board, so as to expose a light-incoming cavity, so that the external light It can be injected into the room through the light inlet cavity to increase the luminous flux. At the same time, the reflective film layer can increase the power generation rate and increase the incident light, making the indoor brightness higher during the day.

Description

technical field [0001] The invention relates to a building curtain wall, in particular to a light and heat collection type energy-saving building curtain wall. Background technique [0002] Building curtain wall is a commonly used exterior wall decoration at present. It is not used as a load-bearing exterior wall. Due to the large surface area of ​​the building curtain wall after laying, many people tend to design the building curtain wall as a photovoltaic curtain wall. However, due to the installation of photovoltaic curtain walls, resulting in The illuminance in the interior of the building is insufficient, so that the external light cannot enter the room through the curtain wall, resulting in insufficient indoor light during the day and a dim situation. At present, some photovoltaic curtain wall panels that can be pulled by hand can be opened to meet the light injection. However, because the opening method is based on motors, etc., the use cost increases, the purchase co...

[0002] Building curtain wall is a commonly used exterior wall decoration at present. It is not used as a load-bearing exterior wall. Due to the large surface area of ​​the building curtain wall after laying, many people tend to design the building curtain wall as a photovoltaic curtain wall. However, due to the installation of photovoltaic curtain walls, resulting in The indoor illuminance of the building is insufficient, so that the external light cannot enter the room through the curtain wall, resulting in insufficient indoor light during the day and a dim situation. At present, some photovoltaic curtain wall panels that can be pulled by hand can be opened to meet the light injection. However, because the opening method is based on motors, etc., the use cost increases, the purchase cost increases, and it is easy to be damaged, and the opened photovoltaic curtain wall panels are not fully opened due to the included angle of travel, so the luminous flux is actually not very good
