Installing method of passive externally hanging window of house

Abstract

The invention discloses an installing method of a passive externally hanging window of a house. The method comprises the following steps of uniformly fixing long-wall ends of a plurality of L-shaped metal fixing plates onto a wall body at the left, right, upper and lower sides of a hole opening; bonding and fixing a circle of waterproof airtight film with most parts extending out of the indoor endonto the outer side of the indoor end of a window frame; fixing the short wall end of the L-shaped metal plate to the window frame; totally covering the outdoor end of the window frame by a waterproof ventilation film in a way of exceeding the edge; bonding the waterproof ventilation film totally covering the L-shaped metal fixing plate into the position of the L-shaped metal fixing plate; fixinga window sill onto the lower end of the outdoor end surface of the window frame at the lower end of the window; totally covering and fixing one layer or multiple layers of graphite polystyrene boardsonto the wall in the position of the waterproof ventilation film; unfolding the waterproof airtight film; pasting the waterproof airtight film onto the wall of the hole opening; and pasting and fixing a wall plate. Installed doors and windows cannot easily generate cracks; the airtightness and water tightness performance is good; seepage cannot easily occur; the heat insulation and thermal isolation performance is good; the heat transfer coefficient is low; and the installation requirements of the passive doors and windows of the house can be met.

Description

technical field [0001] The invention belongs to the field of installation of building doors and windows, and relates to an installation method of an externally hung window of a passive house. 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. At present, there are two types of installation of doors and windows in domestic buildings: dry installation and wet installation. The dry installation of doors and windows generally uses reserved openings, installation of steel sub-frames, and then the installation of window frames. After the installation is completed, the surrounding joints are filled. Due to the strong thermal conductivity of the steel sub-frame, the thermal insulation of the window is poor, which cannot meet the requirements of the low heat transfer coeffic...

AI Technical Summary

Problems solved by technology

When the cross-section of the aluminum material is small and the material is thin, the cement mortar caulking will easily lead to deformation of the aluminum frame. At the same time, the thermal expansion coefficients of the cement and the aluminum frame are different, and the thermal stress generated cannot be eliminated. It can only be absorbed by the deformation of the aluminum frame. After a long time , there will be cracks, resulting in poor airtightness and watertightness, causing leakage and other problems; it also cannot meet the installation requirements of passive doors and windows
