Description

Technical Field

[0001] The utility model relates to the technical field of door and window heat preservation, in particular to a heat-insulating composite profile with an inner flush structure and an installation structure. Background Technique

[0002] The broken bridge aluminum is also called heat-insulating broken bridge aluminum profile, heat-insulating aluminum alloy profile, broken bridge aluminum alloy, broken cold and heat bridge profile, broken bridge type aluminum-plastic composite profile. It has more excellent performance than ordinary aluminum alloy profiles; aluminum alloy is a metal and has relatively fast heat conduction. Therefore, when the temperature difference between indoors and outdoors is large, the aluminum alloy can become a "bridge" for heat transfer. Windows and doors made of such materials have poor heat-insulating performance; while the broken bridge aluminum disconnects the aluminum alloy in the middle and uses hard plastic to connect the disconnected aluminum alloy into one body. The heat conduction of plastic is significantly worse than that of metal, so heat is not easily transferred through the whole material, and the heat-insulating performance of the material is improved. This is the "broken bridge aluminum"; as Figure 1 shown, it is an existing heat-insulating aluminum-plastic co-extruded profile for building doors and windows. The hard plastic profile 901 filled with rigid polyurethane foam material inside the aluminum alloy profile 902. The heat transfer coefficient (UF value) of the window frame body of this profile is greater than 1.0W / m 2 K, and the heat-insulating and heat-preserving performance is poor; and in order to improve the heat-preserving performance of the existing products, it is necessary to increase the thickness of the whole window and select glass with a low heat conduction coefficient at the same time.

[0047] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0048] As Figure 2 、 Figure 4 shown, the present utility model provides a heat-insulating composite profile with an inner flush structure, including a fixed frame and an opening sash. The fixed frame and the opening sash are hinged through a hinge; the connection between the fixed frame and the opening sash is also hermetically connected through a seal.

[0049] The fixed frame includes a first inner aluminum 1 and a first outer aluminum 2, and the first inner aluminum 1 and the first outer aluminum 2 are connected through a first polyurethane core material 3; the opening sash includes a second inner aluminum 4 and a second outer aluminum 5, and the second inner aluminum 4 and the second outer aluminum 5 are connected through a second polyurethane core material 6.

[0050] The thickness of the first inner aluminum 1 is greater than the thickness of the first outer aluminum 2; the thickness of the second inner aluminum 4 is greater than the thickness of the second outer aluminum 5.

[0051] An extension protrusion extending towards the interior is provided on the indoor end face of the first inner aluminum 1. An A cavity 101 is provided inside the extension protrusion, and the plane where the inner end face of the extension protrusion is located coincides with the plane where the second inner aluminum 4 is located.

[0052] 1. For the heat-insulating composite profile with an inner flush structure provided by the present utility model, the first polyurethane core material 3 is used to connect the first inner aluminum 1 and the first outer aluminum 2 to form the fixed frame, and the second polyurethane core material 6 is used to connect the second inner aluminum 4 and the second outer aluminum 5 to form the opening sash. Then, the fixed frame and the opening sash are connected through a connecting member, and the thicknesses of both the first polyurethane core material 3 and the second polyurethane core material 6 are greater than 60 mm, so that the internal and external heat conduction is reduced, and thus the heat transfer coefficient of the window frame body of the heat-insulating profile, that is, the UF value, is lower than 0.8 W / m 2 K; furthermore, due to the overall thickness compression of the first outer aluminum 2 and the second outer aluminum 5, the aluminum usage is reduced, the manufacturing cost is lowered. At the same time, the overall thickness of the heat-insulating profile is reduced, and the thickness ≤ 130 mm. Multiple sizes such as 75 mm, 90 mm, and 95 mm can be achieved, and the heat transfer coefficient of the window frame body, that is, the UF value, can be lower than 0.8 W / m 2 K, with good heat insulation effect. At the same time, the rigidity of the heat-insulating profile can be ensured, the requirement for the thickness of the building wall is reduced, the building cost is saved, and the versatility is higher.

[0053] 2. In the present utility model, an A cavity and a D cavity are respectively added outside the first inner aluminum and the second inner aluminum, further reducing the heat conduction of the composite profile and increasing the heat insulation and heat preservation characteristics of the present utility model; and the inner flush design, that is, the planes where the outer side walls of the A cavity and the D cavity are located coincide, makes the indoor part of the heat insulation profile have no obvious protrusion, avoiding unnecessary losses caused by bumps during transportation and also avoiding bumps by personnel during use.

[0054] The heat insulation and heat preservation composite profile with an inner flush structure provided by the present utility model connects the first inner aluminum 1 and the first outer aluminum 2 with the first polyurethane core material 3, and connects the second inner aluminum 4 and the second outer aluminum 5 with the second polyurethane core material 6. Through the above design and the selection of the first polyurethane core material 3 and the second polyurethane profile 3, the heat insulation performance of the high-strength heat insulation composite profile with an inner flush structure provided by the present utility model is good, and the heat transfer coefficient of the window frame (i.e., the UF value) is lower than 1.0; since the first polyurethane core material 3 and the second polyurethane profile 3 are selected to connect the aluminum profiles, compared with the existing heat insulation profiles, the overall thickness can be less than 100 mm. At the same time, the requirement for the heat insulation coefficient of the glass is reduced, and the configuration of the glass can be appropriately reduced, saving the project cost of the whole window, thus providing a superior energy-saving and heat-insulating profile for promoting low-energy consumption and passive buildings; furthermore, the overall thickness can be less than 100 mm, reducing the requirement for the thickness of the building wall and reducing the construction cost. At the same time, the heat insulation and heat preservation composite profile with an inner flush structure of the present utility model has high strength and good durability, meeting the needs of long-term use of the window.
