A window frame installation structure for passive house windows

Abstract

The invention discloses a passive window frame installation structure of house windows. The outer end surface of the wall body is fixed to a graphite polyphenyl support body. A vertical wall of an L-shape metal fixing plate is fixed to an upper part between the graphite polyphenyl support body and the outer end surface of the wall body. The upper end of a horizontal wall is fixed to a non-metal fixing block. A layer of waterproof breathable film is fixed between the non-metal fixing block and the graphite polyphenyl support body. A batch plate is abutted on the upper end of the graphite polyphenyl support body. The indoor side is fixed to the outer side wall of the non-metal fixing block. Pre-pressure expansion sealing belts are fixed between the indoor side lower end and the waterproof breathable film and the graphite polyphenyl support body. The outdoor side and the outer edge of the graphite polyphenyl plate are fixedly provided with pre-pressure expansion sealing belts. The upper end of the wall body is fixedly provided with an indoor windowsill plate. The window frame is buckled in two buckling hooks of the non-metal fixing block, and is fixed to the non-metal fixing block. The window using the passive window frame is not prone to generate cracks, and has good air tightness and water tightness, the leakage possibility is low, the thermal insulation property is strong, and the coefficient of heat transfer is low.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and relates to a window frame installation structure for passive house windows. Background technique [0002] As life becomes better and better, people pay more and more attention to the quality of life, and the quality and grade of buildings and building envelopes are gradually improved. Passive houses have received more and more attention. Traditional buildings use external protective doors and windows, generally use reserved openings, install steel sub-frames, and then install the window frame body, and then fill in the surrounding joints after the installation is completed. Due to the different materials and thermal expansion coefficients of the window frame and the wall, cracks are prone to appear over a long period of time, and the air and water tightness will deteriorate, causing problems such as leakage; and due to the strong thermal conductivity of the steel sub-frame, the windo...

AI Technical Summary

Problems solved by technology

Due to the different materials and thermal expansion coefficients of the window frame and the wall, cracks are prone to appear over a long period of time, and the air and water tightness will deteriorate, causing problems such as leakage; and due to the strong thermal conductivity of the steel sub-frame, the window will The heat insulation is poor, and it cannot meet the low heat transfer coefficient requirements required by passive houses; and due to the error in the civil construction process, the size of the reserved opening will be deviated, requiring manual leveling, which is time-consuming and laborious, and the cost will increase significantly
