Construction method of gas tightness heat-proof bridge waterproof heat preservation energy-saving external window

Abstract

A construction method of a gas tightness heat-proof bridge waterproof heat preservation energy-saving external window comprises the following steps of window aperture opening, embedded part indwelling, external window fixed mounting and sealing measures, heat preservation plate and sealing mounting measures, window table plate mounting, and wood window sleeve mounting and sealing measures. The external window suspension and external mounting method, break joint heat preservation energy-saving measures, multiple sealing waterproof measures and heat-proof bridge technical measures are adopted to achieve the comprehensive function requirement of the external window heat-proof bridge, waterproof gas tightness and heat preservation energy saving.

Description

technical field [0001] The invention relates to the field of construction of exterior windows of passive buildings, in particular to a construction method for exterior windows with airtight heat-proof bridges, waterproof, thermal insulation and energy saving. Background technique [0002] The traditional external window is installed in the middle area of ​​the wall of the window opening, the window frame and the wall are fixed through the tie of the connector, and the area formed between the installation of the window frame and the wall tie is filled with a foaming agent and then plastered. The resulting problems, one is poor sealing performance, strong air permeability, easy to form air channels and leakage channels; the other is the formation of thermal bridge channels between the window frame and the wall, affecting the thermal insulation performance of the window. In addition, the windows are installed in the middle of the walls, and outdoor rainwater tends to form leaka...

AI Technical Summary

Problems solved by technology

The resulting problems, one is poor sealing performance, strong air permeability, easy to form air channels and leakage channels; the other is the formation of thermal bridge channels between the window frame and the wall, affecting the thermal insulation performance of the window

In addition, the windows are installed in the middle of the wall, and the outdoor rainwater is easy to form a leakage channel between the walls, and the accumulated rainwater seeps into the room through the wall, which has become a common problem affecting the quality of the building.

The thermal insulation and energy-saving measures between the window and the wall are also due to many reasons such as the complex structure of the joints or the lack of deepening of the design. There is a phenomenon that the thermal insulation method cannot be implemented, which affects its energy-saving effect
