Center column structure of external thermal insulation hollow glass casement window frame

Abstract

A center column structure of an external thermal insulation hollow glass casement window frame comprises a center column main body and a center column external thermal insulation part which is arranged on the outer side of the center column main body; each end of the center column external thermal insulation part is connected with an outdoor side fixed casement adhesive strip which is used for clamping the outdoor side of fixed casement glass or one end of a frame external thermal insulation part is connected with an outdoor side fixed casement adhesive strip which is used for clamping the outdoor side of the fixed casement glass and the other end of the frame external thermal insulation part is connected with an opening casement adhesive strip which is used for fixing the outdoor side of an opening casement glass window structure; a fixing part which is used for installing the fixed casement glass is arranged on the indoor side of the center column main body and arranged close to one side of the fixed casement glass; the fixing part is provided with an indoor side fixed casement adhesive strip which is used for clamping the indoor side of the fixed casement glass. According to the center column structure of the external thermal insulation hollow glass casement window frame, the problem of the poor fire protection performance is solved, the design defects of the combination portion with the glass and the connection with other profiles are overcome, the physical strength of the center column structure is significantly increased, and the thermal insulation effect of the changed part in the integral window is enhanced.

Description

technical field [0001] The invention relates to a center column structure of a casement window frame of a building. In particular, it relates to a center column structure of an external thermal insulation hollow glass casement window frame. 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 ...

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] Another example is the joint part of the central column and the opening glazing structure. In the patent No. 201110216628.1, the installation structure with four layers of glass is disclosed. The window structure is connected head-to-head. If a head-to-head connection is used at this position, the airtightness of the connection at this position cannot be guaranteed, and it 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.
