Opening sash structure of an external thermal insulation hollow glass casement window

Abstract

An external thermal insulation hollow glass casement window opening sash structure is provided with combined glass, a left opening sash frame and a right opening sash frame, wherein the left opening sash frame and the right opening sash frame are arranged symmetrically, correspondingly connected with a center pillar structure and a frame structure of a hollow glass casement window respectively and used for fixing the left side of the combined glass and the right side of the combined glass respectively. A left opening sash external thermal insulation piece is connected between the left opening sash frame located on the outdoor side and the left side of the combined glass. A right opening sash external thermal insulation piece is connected between the right opening sash frame located on the outdoor side and the right side of the combined glass. The left opening sash frame and the right opening sash frame are correspondingly connected with the center pillar structure and the frame structure through the left opening sash external thermal insulation piece and the right opening sash external thermal insulation piece respectively. According to the external thermal insulation hollow glass casement window opening sash structure, external cavity thermal insulation materials in an indoor part are eliminated, fire safety and sealing of glass connecting positions are achieved, and the thermal insulation performance is substantially enhanced; by changing the structure of sectional materials, the defects that sashes are high in installation and production difficulty and poor in accuracy and intersecting portions are prone to breakage are overcome.

Description

technical field [0001] The invention relates to a building hollow casement window structure. In particular, it relates to an opening sash structure of an external thermal insulation hollow glass casement window. Background technique [0002] The existing casement window structure adopts aluminum profiles with internal and external thermal insulation materials as the main material of the window frame, and uses external thermal insulation and internal thermal insulation profiles to isolate the frame of the casement window from the air, thereby achieving the effect of thermal insulation. For example, the patent No. 201110216628.1 discloses an internal and external thermal insulation hollow casement window structure with thermal insulation effect. The thermal insulation structure is arranged on the outdoor side and the indoor side, which has a certain thermal insulation effect. There is an insulation structure on the indoor side, and the insulation structure is made of PVC, so ...

Another example is the patent No. 201110216628.1, which discloses the outdoor side frame of the central column used in combination with the external thermal insulation material and the central column. Using this external frame to connect the aluminum profile and the external thermal insulation material will cause the overall shape and firmness of the profile to be affected. damage, thereby reducing the strength of the entire window

[0003] In the patent No. 201110216628.1, the installation structure with four layers of glass is disclosed, which uses aluminum alloy profiles or external insulation materials to carry out head-to-head connection with the glass at this position. If a head-to-head connection is used at this position, it will not be guaranteed. The tightness of the position connection will also have a great negative impact on the thermal insulation performance of the window

Moreover, the combination of the sash frame and the overall casement window frame requires high precision in the manufacturing process, a wide variety of thermal insulation materials, and high processing accuracy requirements for this material, so the production cost is high.

Moreover, the window sash structure and the fixed glass structure given in the patent No. 201110216628.1 are not tightly sealed at the intersection, and the insulation material is prone to breakage, which cannot be realized in actual production.
