Glass curtain wall structure

Abstract

The invention provides a glass curtain wall structure. The glass curtain wall structure includes inner glass, outer glass and a spacing bar; the inner glass is transparent photovoltaic glass, and a photovoltaic cell panel is arranged on the side of the inner glass facing away from the outer glass; the outer glass is light-transmissive tempered glass, and a gap is arranged between the inner glass and the outer glass; the spacing bar is located between the inner glass and the outer glass; the spacing bar, the inner glass and the outer glass enclose a closed cavity; the bottom of the cavity is provided with a number of air inlets; the cavity is connected to a gas supply device through the air inlet; the gas supply device is used for providing inert gas into the cavity. The isolated cavity caneffectively improve the insulation effect of the wall; and when no demand for heating and cooling is required in the room, providing inert gas into the cavity through a gas supply device can reduce the attenuation of the performance of the inner glass and increase the service life.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a glass curtain wall structure. Background technique [0002] In recent years, my country's construction industry energy consumption, industrial energy consumption, and transportation energy consumption have become one of the three major "energy sources". According to statistics, building energy consumption accounts for about 30% of the total energy consumption of the society, plus the consumption of building materials production process, the total energy consumption of the society accounts for 46% to 47%, and the energy consumption of air conditioning accounts for 40% to 50% of the building energy consumption. Existing traditional building materials have poor thermal insulation properties and cannot provide functions such as heat, lighting and air exchange. And when the glass curtain wall is combined with the building, the thermal insulation is worse and the energy ...

Problems solved by technology

When there is no heating demand in the room, since there is no air circulation between the glass interlayers, the breathing curtain wall will easily lead to a reduction in service life under long-term exposure to light, thereby affecting the heat insulation performance of the breathing curtain wall

In addition, the low light transmittance of most photovoltaic curtain walls leads to the obstruction of indoor lighting, and it is necessary to provide indoor lighting, resulting in redundant energy consumption
