Aluminum alloy inward-opening window

Abstract

The invention provides an aluminum alloy inward-opening window. An inward-opening sash and a middle stile are arranged in a frame; pieces of inward-opening sash glass are arranged on inward-opening sash frames through inward-opening sash pressing lines; a fixed sash is arranged between the middle stile and the frame and comprises fixed sash pressing lines and pieces of fixed sash glass; the piecesof fixed sash glass are arranged on the middle stile and the frame through the fixed sash pressing lines correspondingly; each piece of inward-opening sash glass is of a three-layer glass structure;frame heat-insulating bridges, inward-opening sash frame heat-insulating bridges and middle stile heat-insulating bridges are all located between inner side glass bodies and outer side glass bodies ofthe pieces of inward-opening sash glass, and thus an isothermal layer is formed; a grouped angle steel piece is arranged in a clamping groove in the outdoor side bottom edge of the frame, is of a V shape and comprises a first side wing and a second side wing; a first groove is formed in the bonding face of the first side wing and the second side wing; and a rubber injection hole is formed in thefirst groove. The heat-insulating and heat-preservation performance and sealing performance of the aluminum alloy inward-opening window are improved, materials are saved, the universality of the sectional materials is high, and mounting and using are convenient.

Description

technical field [0001] The invention relates to the technical field of building doors and windows, in particular to an aluminum alloy inward opening window. Background technique [0002] The window is an important part of the house structure. It is generally divided into casement windows and sliding windows. Casement windows include inward opening windows and outward opening windows. The disadvantage is that the window width is small and the field of vision is not wide. The inward opening window is a kind of casement window, and the casement window is widely used because it does not occupy indoor space, has a large opening area, and has good sealing and anti-theft performance. With the progress and development of the aluminum alloy industry, aluminum alloys are used as The casement window made of the material of the casement window is even more recognized. Aluminum alloy casement windows have the advantages of light weight, standard profiles, convenient installation, beaut...

AI Technical Summary

Problems solved by technology

Most of the existing aluminum alloy inward opening windows are composed of operating elements including frame, fixed fan, inner opening fan, and middle stiles. Due to the good thermal conductivity of aluminum alloy, the heat conduction between indoors and outdoors is rapid, making the thermal insulation of buildings and buildings The performance is affected. With the increasing requirements of human beings for energy saving and emission reduction, aluminum alloy windows have become an obstacle to energy saving and emission reduction in houses.
