Center pillar structure of internal and external heat insulating hollow glass casement window frame

Abstract

The invention discloses a center pillar structure of an internal and external heat insulating hollow glass casement window frame. The center pillar structure comprises a main body frame of which one side is used for supporting and fixing glass and the other side is used for supporting a sash, an outdoor side frame arranged on the outdoor side of the main body frame, an external heat insulating piece arranged on the outdoor side of the outdoor side frame, a second internal heat insulating piece arranged on the indoor side of the main body frame, plugs arranged at upper and lower ends of the main body frame, a fixing piece connected to the indoor side of the main body frame, positioned on a fixed glass window side and used for fixing the glass, and an internal heat insulating piece arrangedat the periphery of the fixing piece. A plurality of cavities, a lower hook positioned on the outdoor side of the main body frame and used for combining the outdoor side frame, and two grooves symmetrically formed on two sides of the inner end of the main body frame are integrally formed on the main body frame, wherein one groove is used for combining the fixing piece. By the center pillar structure, the contact area of an aluminum section and the air tends to zero, the heat exchange of the center pillar structure due to air convection is prevented, the heat insulation property is improved and the aim of saving energy is fulfilled.

Description

technical field [0001] The invention relates to a center column structure of a casement window frame. In particular, it relates to a center column structure of a casement window frame of a hollow glass casement window with good thermal insulation effect inside and outside. 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. For the window frame structure of the casement window frame, 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 insu...

AI Technical Summary

Problems solved by technology

Most of the window frames are made of aluminum profiles with strong thermal conductivity, so the window frame structure of the existing casement window frame has fast heat transfer, and it is easy to quickly transfer the indoor temperature to the outdoor, so the thermal insulation is poor

Patent No. 20101023926.7 discloses a thermal insulation hollow casement window frame structure with thermal insulation effect. The thermal insulation structure is set on the outdoor side, which has a certain thermal insulation effect. However, it only sets the thermal insulation structure on the outdoor side. structure, so its insulation effect is relatively poor

And because the combination of the casement window frame and the sash frame is a wedge-shaped combination, the production process requires high precision, so the production cost is high
