Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and relates to a split door and window structure. Background Art

[0002] For seamless welded window sashes, considering the technical difficulties of grinding and spraying after welding, the indoor profile and the outdoor profile are usually welded and then sprayed with two different colors.

[0003] The patent with authorization announcement number CN209959058U discloses a fully welded integral composite aluminum profile frame and window, which is composed of inner frame aluminum and outer frame aluminum. The outer frame aluminum and the inner frame aluminum are welded into one piece by aluminum profiles, and the welded outer frame aluminum and the welded inner frame aluminum are bonded and fixed by polyurethane thermal insulation glue.

[0004] The above-mentioned profile frame uses polyurethane insulation glue to connect the window sashes of different colors inside and outside, but there are some shortcomings: for commercial high-rise buildings, the color of the window sashes on the facade may be changed uniformly as needed, but the aluminum outside the frame cannot be disassembled independently, and the cost of changing the color of the entire window frame is too high. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a split door and window structure. The technical problem to be solved by the utility model is that the cost of changing the color of the outer side of the prior door and window is high.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A split door and window structure comprises an outer window sash and an inner window sash fixedly connected to each other, characterized in that the outer window sash has a positioning portion on the side facing away from the inner window sash, and the door and window structure also comprises an outer pressure wire plate connected to the outer side of the outer window sash, the outer pressure wire plate has a positioning groove on the side facing the outer window sash, the positioning portion is embedded in the positioning groove, and the outer pressure wire plate is provided with a screw that penetrates the outer pressure wire plate from the outside and is fixed to the positioning portion.

[0008] The outer window sash and the inner window sash are respectively the profile structures on the outside and inside of the window frame body. The outer window sash and the inner window sash are generally fixedly connected by a heat insulation strip. A positioning portion is provided on the outer window sash, and a positioning groove and the positioning portion are provided on the inner side of the outer pressure plate for positioning, and the screws pass through the outer pressure plate from the outside and are fixedly connected to the positioning portion. The outer pressure plate and the outer window sash can be accurately and stably connected to prevent the outer pressure plate from being easily detached due to external wind and rain, and the outer pressure plate will not cover the outer window sash. When the spray color on the outside of the window frame needs to be replaced, the outer pressure plate can be completely removed and replaced by removing the screws from the outside without the need to remove the outer window sash entirely. Since the weight and profile occupancy of the outer pressure plate itself can be controlled within a smaller range, the cost of replacement can be greatly reduced.

[0009] In the above-mentioned split door and window structure, the outer pressure plate is arranged along the length direction of the outer window sash, and the outer pressure plate is connected with a glass sealing strip at one side along the width direction. The positioning part includes a connecting plate and a positioning plate both arranged along the length direction of the outer window sash, and the connecting plate and the positioning plate are arranged at intervals along the width direction of the positioning groove. The thickness of the connecting plate is greater than the thickness of the positioning plate, and the screw is located at the side of the outer pressure plate away from the glass sealing strip and is vertically fixed to the connecting plate. In this way, the glass sealing strip at one side of the outer pressure plate can form a seal with the glass in the window frame to prevent external rainwater from invading the inside of the profile and causing corrosion. The positioning part includes a connecting plate and a positioning plate arranged at intervals, which can be positioned and matched with the positioning groove. The hollow space between the connecting plate and the positioning plate is conducive to lightweight and cost control of the profile, and the connecting plate has a larger thickness to ensure the connection stability with the screw. The positioning part can also be a solid block, so that the small end of the screw is inserted into the positioning part.

[0010] In the above-mentioned split door and window structure, the connecting plate and the positioning plate are both against the bottom surface of the positioning groove, and a gap is left between the side of the positioning plate and the inner wall of the relative positioning groove. This eliminates the normal activity space of the outer pressure plate, which is conducive to avoiding instability between the outer pressure plate and the outer window sash due to wind and rain. At the same time, the width of the positioning groove is designed to be slightly larger, which is conducive to the connecting plate and the positioning plate being smoothly embedded and positioned when the connecting plate or the outer pressure plate is deformed due to processing or expansion and contraction, ensuring smooth replacement and installation.

[0011] In the above split door and window structure, the side edges of the connecting plate and / or the positioning plate are processed with rounded corners or chamfered corners, so that the connecting plate and the positioning plate can be inserted into the positioning groove more smoothly and labor-savingly, ensuring convenient replacement.

[0012] In the above-mentioned split-type door and window structure, the side of the outer pressure plate has a protective groove that is open toward the side away from the glass sealing strip, and the screw is located in the protective groove. In this way, after installation, the protective groove can provide shielding protection for the large end of the screw, which is conducive to preventing the intrusion of external dust, and the protective groove is convenient for embedding a sealing strip, which can seal the screw inside, preventing external rainwater from intruding into the screw and causing corrosion and affecting disassembly.

[0013] Compared with the prior art, the advantages of the utility model are as follows:

[0014] The split-type door and window structure can independently disassemble and replace the outer pressure line plate part to achieve color change when changing the outer color. The outer pressure line plate itself is light in weight, low in cost and easy to disassemble and assemble, which is beneficial to greatly reduce the cost of changing the color of the outer side of the window frame.
