Description

External window heat-insulation joint for double-sided prefabricated shear wall

Technical Field

The utility model relates to a building exterior window design field especially relates to an exterior window heat preservation node for two-sided precast shear wall.

Background

Under the background of global warming and energy shortage, building energy conservation with high energy efficiency and low emission as the core plays a crucial role in realizing energy safety and sustainable development of the country. Therefore, the design of the residential building with the heat preservation integration of the double-sided prefabricated superposed shear wall is usually adopted at present, and the assembly rate can be ensured while the energy conservation of the building is ensured. For building energy consumption, the heat loss through the window can usually account for 25% -30% of the total building heat loss, and the heat loss of the outer window directly influences the energy consumption index of the building as a weak part of the heat exchange between the building and the outside. However, in the prior art, the connection node of the prefabricated wall panel and the external window is easy to have a thermal bridge effect, so that a large amount of heat loss is generated, and the building cost is increased.
