A center column structure of a casement window frame of an external thermal insulation hollow glass casement window

Abstract

A center column structure for a casement window frame of a hollow glass casement window with external thermal insulation, comprising a center column main body, a center column outer thermal insulation part arranged outside the room of the center column main body, and the two ends of the center column outer thermal insulation part respectively The outdoor side fixed fan rubber strip used for clamping and fixing the outside of the glass room of the fixed fan is connected, or one end of the outer frame insulation part is connected with the outdoor side fixed fan rubber strip used for clamping and fixing the outside of the glass room of the fixed fan, and the other end is connected with a useful To fix the opening sash strip on the outdoor side of the opening sash window structure, the interior side of the main column main body and the side adjacent to the fixed sash glass are provided with a fixing piece for installing the fixed sash glass, and the fixing piece is provided with a Clamp the indoor side fixed fan rubber strips on the inner side of the fixed fan glass room. The invention solves the problem of poor fire protection performance; changes the design defects of the joint part with the glass and other profiles, greatly increases the physical strength of the central column structure, and enhances the thermal insulation effect of the modified part in the whole window.

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.
