Description

Technical Field

[0001] This utility model relates to the technical field of doors and windows, and particularly to a casement window with a combined structure. Background Technology

[0002] Windows and doors are an important part of buildings. With the development of technology, the earliest windows were made of wood as the main raw material. With further development, most windows and doors are now made of aluminum profiles. Aluminum profile windows are widely used due to their lightweight, high strength, corrosion resistance, and aesthetics. However, because aluminum is a good conductor of heat, the insulation effect of current inward-opening windows is relatively poor. Therefore, most casement windows now use thermal break profiles. This is achieved by dividing the fixed frame and sash frame into indoor and outdoor profiles, and then connecting the two profiles with thermal break adhesive. The thermal break adhesive separates the profiles to form a thermal break structure to prevent heat conduction from the aluminum profile. However, this structure, which adds thermal break adhesive between the two profiles, results in an excessively thick overall casement window. Currently, there is an urgent need to solve the heat conduction problem of aluminum profile casement windows. Utility Model Content

[0003] The present invention provides a casement window with a combined structure to solve the heat conduction problem of existing casement windows.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a casement window with a combined structure, comprising a fixed frame and a sash frame. The fixed frame includes a first indoor profile frame and a first outdoor thermal insulation frame connected to each other. The sash frame includes a second indoor profile frame and a second outdoor thermal insulation frame connected to each other. Both the first outdoor thermal insulation frame and the second outdoor thermal insulation frame are made of polyurethane. When the casement window is closed, the first indoor profile frame overlaps with the second indoor profile frame, and the first outdoor thermal insulation frame overlaps with the second outdoor thermal insulation frame.

[0005] Furthermore, the fixed frame has a window opening, the sash frame is disposed inside the window opening, an overlapping plate is disposed on the outer side of the second outdoor heat insulation frame, and an abutment strip is disposed on the inner side of the window opening, which overlaps the overlapping plate.

[0006] Furthermore, the first outdoor heat insulation frame is provided with a baffle plate a on its outdoor side, and the baffle plate a is provided with a first adhesive strip that overlaps with the second outdoor heat insulation frame. The second indoor profile frame is provided with a baffle plate b on its indoor side, and the baffle plate b is provided with a second adhesive strip that overlaps with the first indoor profile frame.

[0007] Furthermore, both the first outdoor heat insulation frame and the second outdoor heat insulation frame are provided with at least two inner cavities, and the inner cavities are arranged from front to back in the direction of the fixed frame thickness.

[0008] Furthermore, the inner cavity is filled with expanding foam.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by using a first outdoor heat insulation frame and a second outdoor heat insulation frame made of polyurethane to replace the existing aluminum profile, the outdoor side frame of the fixed frame and sash frame is formed. By using the combination structure of polyurethane and aluminum, the thermal conductivity of the casement window is reduced while the overall thickness of the casement window is also reduced.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] As shown in the attached drawings, the present invention discloses a casement window with a combined structure, comprising a fixed frame 1 and a sash frame 2. The fixed frame 1 includes a first indoor profile frame 10 and a first outdoor thermal insulation frame 20 connected to each other. The sash frame 2 includes a second indoor profile frame 30 and a second outdoor thermal insulation frame 40 connected to each other. Both the first outdoor thermal insulation frame 20 and the second outdoor thermal insulation frame 40 are made of polyurethane. When the casement window is closed, the first indoor profile frame 10 overlaps with the second indoor profile frame 30, and the first outdoor thermal insulation frame 20 overlaps with the second outdoor thermal insulation frame 40. The indoor sides of the first outdoor thermal insulation frame 20 and the second outdoor thermal insulation frame 40 are provided with connecting protrusions, and the outdoor sides of the first indoor profile frame 10 and the second indoor profile frame 30 are provided with snap-fits that cooperate with the connecting protrusions. By using a first outdoor thermal insulation frame 20 and a second outdoor thermal insulation frame 40 made of polyurethane to replace the existing aluminum profile, the outdoor side frame of the fixed frame 1 and the sash frame 2 is formed. The combination structure of polyurethane and aluminum reduces the thermal conductivity of the casement window while also reducing the overall thickness of the casement window.

[0016] Specifically, the fixed frame 1 has a window opening, the sash frame 2 is disposed inside the window opening, the outer side of the second outdoor heat insulation frame 40 is provided with an overlapping plate 401, and the inner side of the window opening is provided with an abutment strip 220 overlapping the overlapping plate 401.

[0017] Specifically, the first outdoor heat insulation frame 20 is provided with an a baffle 201 on the outdoor side, and the a baffle 201 is provided with a first adhesive strip 221 that overlaps with the second outdoor heat insulation frame 40. The second indoor profile frame 30 is provided with a b baffle 301 on the indoor side, and the b baffle 301 is provided with a second adhesive strip 332 that overlaps with the first indoor profile frame 10. When the window is closed, the abutting adhesive strip 220 and the overlapping plate 401 overlap each other, and a triple sealing structure is formed by the first adhesive strip 221 and the second adhesive strip 332, which further improves the heat insulation performance of the casement window.

[0018] Specifically, both the first outdoor heat insulation frame 20 and the second outdoor heat insulation frame 40 are provided with at least two inner cavities 400, and the inner cavities 400 are arranged from front to back along the thickness direction of the fixed frame 1. The first outdoor heat insulation frame 20 and the second outdoor heat insulation frame 40 are equipped with baffles at intervals, thereby dividing the internal space into independent inner cavities 400 to block heat conduction. The inner cavities 400 are filled with expanding foam, which can also be polyurethane, to further improve the overall strength and sealing performance of the window.

[0019] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
