Abstract
Description
Technical Field
[0001] This utility model relates to the field of building system doors and windows technology, and in particular to a building system door and window made of aluminum-plastic co-extruded material. Background Technology
[0002] Building doors and windows are an important component of the building envelope. Besides meeting various functional and performance requirements, they also bear significant responsibility for energy conservation. After more than 40 years of development, my country's economy has shifted from a phase of high-speed growth to one of high-quality development, placing higher demands on the energy efficiency of doors and windows in building envelopes. Aluminum-plastic co-extruded (APU) doors and windows have emerged and developed rapidly. However, existing APU door and window manufacturers still design and process their products using traditional methods, without systematically researching and developing various elements of doors and windows, including materials, structure, form, technology, and performance. Current APU doors and windows are still conventional rather than system-wide. Specifically, each existing APU door and window product can only solve one demand; similar elements, including main functional components, accessories, hardware, and sealing systems, are not related to other doors and windows in the same series. The disadvantages include low profile yield, significant material waste, large warehouse space occupied by profiles, accessories, and components with different functions, low capital utilization efficiency, and generally low profits for enterprises. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a building system door and window made of aluminum-plastic co-extruded material.
[0004] The technical solution of this utility model is: an aluminum-plastic co-extruded building system door and window, which consists of an outer frame, a mullion, and glass sashes; glass is provided between the upper part of the outer frame and the mullion, and between the two glass sashes; the outer frame, mullion, and glass sashes are all composed of an outer profile assembly and an inner profile assembly; the outer profile assembly includes an outer panel and an outer profile; the outer panel and the outer profile are connected by a first thermal insulation structure; a first thermal insulation layer is co-extruded on both sides of the first thermal insulation structure; the outer profile and the inner profile assembly are connected by a second thermal insulation structure.
[0005] The inner profile assembly has a second insulation layer co-extruded on both sides.
[0006] The inner profile assembly includes an inner panel and an inner profile; the inner panel and the inner profile are connected by a third thermal insulation structure; the second thermal insulation structure is disposed between the inner profile and the outer profile; a second insulation layer is co-extruded on both sides of the third thermal insulation structure.
[0007] A second insulation layer is co-extruded on the outside of the inner profile assembly.
[0008] The inner profile assembly includes an inner panel and an inner profile; the inner panel and the inner profile are connected by a third thermal insulation structure; the second thermal insulation structure is disposed between the inner profile and the outer profile; a second insulation layer covering the inner panel, the third thermal insulation structure and the inner profile is co-extruded on the outer side of the inner panel and the inner profile.
[0009] The first thermal insulation structure includes at least two first thermal insulation strips; the outer panel and the outer profile are connected and fixed by the first thermal insulation strips, and a first thermal insulation cavity is formed between the outer panel, the outer profile and the first thermal insulation strips; the first thermal insulation cavity is filled with a first thermal insulation filler.
[0010] The second thermal insulation structure includes at least two second thermal insulation strips; the inner profile assembly and the outer profile are connected and fixed by the second thermal insulation strips, and a second thermal insulation cavity is formed between the inner profile assembly, the outer profile and the second thermal insulation strips; the second thermal insulation cavity is filled with a second thermal insulation filler.
[0011] The third thermal insulation structure includes at least two third thermal insulation strips; the inner profile and the outer profile are connected and fixed by the third thermal insulation strips, and a third thermal insulation cavity is formed between the inner profile assembly, the outer profile and the second thermal insulation strip; the third thermal insulation cavity is filled with a third thermal insulation filler.
[0012] Both the first and second insulation layers are PVC micro-foamed insulation layers formed by aluminum-plastic co-extrusion process.
[0013] The first, second, and third thermal insulation fillers are all honeycomb-shaped.
[0014] The above-mentioned technical solution has the following beneficial effects: (1) The present invention connects the outer panel and the outer profile through the first heat insulation structure and connects the outer profile and the inner profile body through the second heat insulation structure, forming multiple thermal resistance barriers. Combined with the first heat insulation layer co-extruded on both sides, it effectively blocks the heat conduction path, so that the door and window profile has good heat insulation and heat insulation properties. The increase of the heat insulation cavity can significantly improve the sound insulation performance of the door and window. In addition, the combination of the outer profile and sealing structure of the present invention with different inner profile bodies can construct heat insulation aluminum-plastic co-extruded system doors and windows with different K values or U values, which can meet the personalized needs of the project and reduce costs. In addition, the present invention upgrades the traditional door and window enterprise to the system door and window enterprise, which can reduce inventory pressure, reduce waste and improve material utilization, reduce enterprise capital occupation, and significantly improve the enterprise's economic benefits.
[0015] (2) This utility model prepares the outdoor profile as a heat-insulating aluminum-plastic co-extruded profile, and its heat-insulating micro-foamed layer is co-extruded on the inner wall of the aluminum profile, which solves the problems of the co-extruded layer being exposed to the outdoors for a long time, being not weather-resistant, brittle, easy to fade, and having complicated processing and assembly processes.
[0016] (3) This utility model has an extremely low heat transfer coefficient, which can block the heat from the outside as much as possible at the outermost or innermost edge of the effective sealing structure of the window, effectively preventing the heat from the outside from seeping in or dissipating through the window, reducing the exchange of heat between indoors and outdoors, reducing heating and cooling energy consumption, avoiding heat loss caused by heat transfer, and helping to maintain stable indoor temperature. It is the first choice for high-performance doors and windows in green buildings and passive house doors and windows, further reducing carbon emissions. Attached Figure Description
