Outer window structure suitable for passive-type low-energy-consumption buildings and installation method thereof

Abstract

The invention relates to an outer window structure suitable for passive-type low-energy-consumption buildings and an installation method thereof, and belongs to the technical field of building energy saving technologies. The outer window structure comprises an outer wall, an outer window and insulation materials; the window frames of the outer window are provided with fixing points, all the fixing points are connected with the outer wall through expansion bolts, screws and stainless angle steel, rock wool is filled in the outer embedding positions of the outer wall and the outer window frames, and the outer embedding positions are sealed through waterproof cloth; the contact faces of the inner sides of the window frames and the outer wall are provided with prepressing expansion seal belts; the inner sides and the outer sides of the joints of the outer wall and the window frames are each coated with a layer of sealing gum. According to the outer window structure, efficient and airtight construction of the passive-type low-energy-consumption buildings can be achieved on the condition that the outer wall is not provided with an insulation layer or the insulation layer is thin, and the obvious economical benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to an exterior window structure and an installation method thereof, in particular to an exterior window structure suitable for passive low-energy buildings and an installation method thereof, and belongs to the technical field of building energy conservation. Background technique [0002] In today's society, energy issues have become the focus of people's increasing attention. Due to the acceleration of my country's urbanization process in recent years, the increase in the number and scale of cities and towns, the area of ​​newly built buildings is also growing rapidly every year, and the annual consumption of commodity energy in construction accounts for one-third of the total terminal energy consumption of the whole society. The increase in energy consumption has already reached 25% of the country's greenhouse gas emissions, and problems such as energy depletion and environmental pollution caused by high energy consumption and hi...

AI Technical Summary

Problems solved by technology

[0004] At present, the external windows of passive low-energy buildings generally adopt the external installation method. When the thickness of the insulation layer of the outer protective structure cannot completely wrap the external windows, the external installation method will destroy the airtight layer of the building and fail to reach Requirements for Airtightness of Passive Low Energy Buildings

At the same time, due to the production of new insulation materials such as VIP vacuum insulation panels, the heat transfer coefficient of insulation materials has been greatly reduced
