Description

Technical Field

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

[0002] The broken bridge aluminum is also called heat-insulating broken bridge aluminum profile, heat-insulating aluminum alloy profile, broken bridge aluminum alloy, heat-insulating and cold-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 there is a large temperature difference between indoors and outdoors, the aluminum alloy can become a "bridge" for heat transfer. When such materials are made into doors and windows, the heat-insulating performance is not good; 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 is 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 / m2K, and the heat-insulating and heat-preserving performance is poor; and for existing products to improve the heat-preserving performance, it is necessary to increase the thickness of the whole window and select glass with a low heat conduction coefficient at the same time. However, the price of glass with a low heat conduction coefficient is generally high, and the increase in the thickness of the whole window has strict requirements for the building wall, increasing the building cost and restricting the popularization and use.

[0003] Therefore, in view of the above problems, the utility model urgently provides a high-strength heat-insulating composite profile with an inner flush structure and an installation structure. Content of the Utility Model

[0047] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0048] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0049] 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" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can 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.

[0050] As Figure 2 , Figure 4 shown, the present utility model provides a heat-insulating composite profile with a high-strength flush-in structure, including a fixed frame and an opening sash, and 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 sealing member;

[0051] 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;

[0052] 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;

[0053] The indoor end face of the first inner aluminum 1 is provided with a first extending protrusion extending towards the indoor side, and an A cavity 101 is arranged inside the first extending protrusion, and the plane where the inner end face of the first extending protrusion is located coincides with the plane where the second inner aluminum 4 is located;

[0054] The outdoor end face of the first outer aluminum 2 is provided with a second extending protrusion extending towards the outdoor side, and a D cavity 202 is arranged inside the second extending protrusion, and an E cavity 206 is formed by enclosing the side of the second extending protrusion close to the second outer aluminum 5 and the first outer aluminum 2.

[0055] As Figure 9 shown, the screen window 19 is connected and installed to the E cavity 206 through screws.

[0056] 1. The heat-insulating composite profile with an internal flush structure provided by the present utility model connects the first inner aluminum 1 and the first outer aluminum 2 through the first polyurethane core material 3 to form a fixed frame, and connects the second inner aluminum 4 and the second outer aluminum 5 through the second polyurethane core material 6 to form an opening sash. Then, the fixed frame and the opening sash are connected through connectors. Moreover, the thicknesses of both the first polyurethane core material 3 and the second polyurethane core material 6 are greater than 60 mm, reducing the internal and external heat conduction, so that 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 / m²K. Furthermore, due to the overall thickness compression of the first outer aluminum 2 and the second outer aluminum 5, the aluminum consumption is reduced, and the manufacturing cost is lowered. At the same time, the overall thickness of the heat-insulating profile is reduced, with the thickness ≤ 130 mm. It can achieve various dimensions such as 75 mm, 90 mm, and 95 mm, and can all achieve that the heat transfer coefficient of the window frame body, that is, the UF value, is lower than 0.8 W / m²K. It has good heat preservation effect, can ensure the rigidity of the heat-insulating profile at the same time, reduce the requirement for the thickness of the building wall, save the building cost, and has higher versatility.

[0057] 2. In the present utility model, an A cavity and a D cavity are respectively installed outside the first inner aluminum and the second inner aluminum, further reducing the heat conduction of the composite profile and increasing the heat-insulating and heat-preserving characteristics of the present utility model. And the internal 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-insulating profile have no obvious protrusion, avoiding unnecessary losses caused by bumps during transportation and also avoiding bumps by personnel during use. At the same time, the design of the E cavity of the first outer aluminum of the present utility model provides an installation space and installation conditions for the window screen, so that there is no need to additionally increase a window screen installation structure, saving the installation cost.

[0058] The high-strength heat-insulating composite profile with an internal 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-insulating performance of the high-strength heat-insulating composite profile with an internal flush structure provided by the present utility model is good, and the heat conduction coefficient of the window frame (that is, 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-insulating profiles, the overall thickness can be less than 100 mm. At the same time, the requirement for the heat-insulating 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, it provides a superior energy-saving and heat-preserving 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 lowering the building cost. At the same time, the super energy-saving heat-insulating profile of the present utility model has high strength and good durability, meeting the needs of long-term use of the window.
