Inner and outer heat insulation hollow casement window structure

Abstract

The invention relates to an inner and outer heat insulation hollow casement window structure. A framework structure comprises a left side frame, a right side frame and a central column positioned between the left side frame and a right side frame; a fixed glass window is arranged in a left groove and a right groove formed by the left side frame and the central column, a window sash is arranged between the central column and the right side frame and mounted on the right side frame; a first outer heat insulation part, a second outer heat insulation part and a third outer heat insulation part are respectively arranged on the outdoor sides of the left side frame, the central column and the right side frame, a first inner heat insulation part, a second inner heat insulation part, a third innerheat insulation part, a fourth inner heat insulation part and a fifth inner heat insulation part are respectively arranged on the indoor sides of the left side frame, the central column and the rightside frame, the fixed glass window and the window sash are in hollow structures formed by a plurality of layers of glass, and the multiple layers of the glass are hermetically connected through heat insulation sealing parts. The inner and outer heat insulation hollow casement window structure is simple in structure, convenient to manufacture and assembly; the contact area between an aluminum profile and atmosphere tends to be zero, the heat exchange of an aluminum alloy framework caused by air convection can be prevented, thereby improving the heat insulation performance and achieving the purpose of saving energy.

Description

technical field [0001] The invention relates to a hollow casement window structure. In particular, it relates to a hollow casement window structure with internal and external thermal insulation with high thermal insulation strength. Background technique [0002] Existing casement window structure is to adopt the aluminum section material with heat insulation bridge to make the main material of window frame, connect with plastic between two closed aluminum materials, have dovetail to fix between the two, play the effect of heat insulation. As for the frame structure of the casement window, the prior art mostly exposes the window frame to the atmosphere. Most of the window frames are made of aluminum profiles with strong thermal conductivity, so the window frame structure of the existing casement window frames has fast heat transfer, and it is easy to quickly transfer the indoor temperature to the outdoor, so the thermal insulation is poor. In the patent No. 20101023926.7, a...

However, this only applies to installations with one layer of glass

Similarly, the patent No. 20101023926.7 discloses the installation structure of three layers of glass, which is provided with insulating strips between adjacent two layers of glass, and the groove of the aluminum profile sash frame is set wider, Makes it capable of accommodating triple glazing with insulating strips
