Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy door and window frame reinforcing ribs, specifically an aluminum alloy door and window frame reinforcing rib structure. Background Technology

[0002] Aluminum alloy doors and windows are widely used in the construction industry due to their advantages such as light weight, high strength, strong corrosion resistance, and good processing performance. In the structure of aluminum alloy doors and windows, the frame is a crucial component, bearing key functions such as fixing the glass, withstanding external wind pressure, and ensuring the overall stability of the door and window. To meet these functional requirements, reinforcing rib structures are designed and applied to the aluminum alloy door and window frames to enhance the frame's resistance to deformation and overall strength.

[0003] Existing aluminum alloy door and window frame reinforcing rib structures have some shortcomings. Traditional reinforcing ribs are mostly made of a single aluminum alloy material, with a relatively simple cross-sectional shape, usually rectangular or "T"-shaped. While this structure can improve the frame's strength to some extent, it is still prone to deformation under high wind pressure or external impact. Furthermore, single-material reinforcing ribs perform poorly in terms of thermal insulation, failing to effectively block the transfer of heat between the interior and exterior, thus limiting the thermal insulation performance of doors and windows.

[0004] Therefore, a reinforcing rib structure for aluminum alloy door and window frames is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this paper addresses some deficiencies in the current reinforcing rib structures of aluminum alloy door and window frames. Traditional reinforcing ribs are mostly made of a single aluminum alloy material with a relatively simple cross-sectional shape, typically rectangular or "T"-shaped. While this structure can improve the frame's strength to some extent, it is still prone to deformation under high wind pressure or external impact. Furthermore, single-material reinforcing ribs perform poorly in terms of thermal insulation, failing to effectively block the transfer of heat between the interior and exterior, thus limiting the thermal insulation performance of doors and windows.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The aluminum alloy door and window frame reinforcing rib structure of this utility model includes an outer aluminum alloy frame, a reinforcing rib assembly installed inside the outer aluminum alloy frame, and a heat insulation layer fixedly connected to the side of the reinforcing rib assembly, and an inner aluminum alloy frame fixedly connected to the outside of the heat insulation layer; the reinforcing rib assembly includes an outer reinforcing rib, a connector fixedly connected to the outside of the outer reinforcing rib, and an inner reinforcing rib fixedly connected to the outside of the connector.

[0007] Preferably, both the outer reinforcing rib and the inner reinforcing rib are made of aluminum alloy, and the thickness of the outer reinforcing rib is greater than that of the inner reinforcing rib. The thickness of the outer reinforcing rib is three to five millimeters, and the thickness of the inner reinforcing rib is two to three millimeters.

[0008] Preferably, the connector is made of high-strength aluminum alloy and is shaped like a "Z". The two ends of the connector are fixedly connected to the outer reinforcing rib and the inner reinforcing rib by welding, respectively. The welding points are evenly distributed and the spacing between the welding points is 10 to 15 centimeters.

[0009] Preferably, the outer surface of the outer reinforcing rib is coated with an anti-corrosion coating, and the thickness of the anti-corrosion coating is 0.1 mm to 0.3 mm, and the material of the anti-corrosion coating is epoxy resin.

[0010] Preferably, the thickness of the insulation layer is five to ten millimeters, and the material of the insulation layer is polyurethane foam.

[0011] Preferably, the outer surface of the outer aluminum alloy frame is coated with an anti-corrosion coating, and the thickness of the anti-corrosion coating is 0.1 to 0.3 millimeters.

[0012] The advantages of this utility model are:

[0013] 1. By employing a double-layer reinforcing structure—a combination of outer and inner reinforcing ribs—the strength and deformation resistance of the door and window frames are significantly improved. The thicker outer reinforcing rib effectively withstands external wind pressure and impact forces, while the inner reinforcing rib further enhances the overall structural stability. This double-layer design allows the doors and windows to maintain their shape and function under harsh weather conditions or external forces, effectively extending their service life. Secondly, the ingenious design of the connectors further enhances the structural stability of the reinforcing rib assembly. The connectors are made of high-strength aluminum alloy and are Z-shaped, a structure that evenly distributes external forces and avoids stress concentration.

[0014] 2. The outer and inner reinforcing ribs are fixedly connected by welding, with evenly distributed weld points ensuring a strong and reliable connection. The spacing between weld points is precisely calculated, guaranteeing structural stability while avoiding material waste and structural deformation caused by excessive welding. Furthermore, the tight fit between the reinforcing rib assembly and the insulation layer significantly improves the thermal insulation performance of the doors and windows. The insulation layer uses polyurethane foam, which has excellent thermal insulation properties and can effectively block the transfer of heat between the indoor and outdoor areas.

[0015] 3. The thickness of the insulation layer is optimized to ensure effective insulation without compromising the overall structure and appearance of the doors and windows. This insulation layer, combined with the reinforcing rib assembly, effectively blocks external heat from entering the room during summer, reducing air conditioning energy consumption; and in winter, it minimizes heat loss and improves indoor temperature stability. Furthermore, the outer surface of the reinforcing rib assembly is coated with an epoxy resin anti-corrosion coating, which has excellent corrosion resistance and effectively prevents corrosion of the reinforcing ribs in humid environments.

[0016] 4. The thickness of the anti-corrosion coating is precisely controlled, ensuring both its protective effect and the mechanical properties of the reinforcing ribs. This anti-corrosion design significantly extends the service life of the reinforcing ribs and reduces the maintenance costs of doors and windows. Finally, the outer surface of the aluminum alloy frame is also coated with an anti-corrosion coating, further enhancing the weather resistance and corrosion resistance of the entire door and window frame. This dual anti-corrosion design allows doors and windows to maintain good appearance and performance under various climatic conditions, eliminating the need for frequent replacement or maintenance.

[0024] Example 1

[0025] like Figure 1 The diagram shows a reinforcing rib structure for an aluminum alloy door and window frame, comprising an outer aluminum alloy frame 1, a reinforcing rib assembly 2, a heat insulation layer 3, and an inner aluminum alloy frame 4.

[0026] Please see Figure 1 and Figure 4 The diagram illustrates a reinforcing rib structure for an aluminum alloy door and window frame, comprising an outer aluminum alloy frame 1, with a reinforcing rib assembly 2 installed inside the outer aluminum alloy frame 1. A heat insulation layer 3 is fixedly connected to the side of the reinforcing rib assembly 2, and an inner aluminum alloy frame 4 is fixedly connected to the outside of the heat insulation layer 3. The reinforcing rib assembly 2 includes an outer reinforcing rib 201, with a connector 202 fixedly connected to the outside of the outer reinforcing rib 201, and an inner reinforcing rib 203 fixedly connected to the outside of the connector 202. Both the outer reinforcing rib 201 and the inner reinforcing rib 203 are made of aluminum alloy, and the thickness of the outer reinforcing rib 201 is greater than the thickness of the inner reinforcing rib 203. The thickness of the outer reinforcing rib 201 is three to five millimeters, and the thickness of the inner reinforcing rib 203 is... The thickness is two to three millimeters; the connector 202 is made of high-strength aluminum alloy and is shaped like a "Z". The two ends of the connector 202 are fixedly connected to the outer reinforcing rib 201 and the inner reinforcing rib 203 by welding, respectively. The welding points are evenly distributed and the spacing between the welding points is ten to fifteen centimeters; the outer surface of the outer reinforcing rib 201 is coated with an anti-corrosion coating, and the thickness of the anti-corrosion coating is 0.1 to 0.3 millimeters. The material of the anti-corrosion coating is epoxy resin; the thickness of the heat insulation layer 3 is five to ten millimeters, and the material of the heat insulation layer 3 is polyurethane foam; the outer surface of the outer aluminum alloy frame 1 is coated with an anti-corrosion coating, and the thickness of the anti-corrosion coating is 0.1 to 0.3 millimeters.

[0027] Working principle: The outer aluminum alloy frame 1 serves as the "outer protective and basic support frame" of the entire door and window frame. The anti-corrosion coating material with a thickness of 0.1-0.3 mm on its outer surface is the same as the anti-corrosion coating of the outer reinforcing rib 201, which has excellent weather resistance and can directly resist the corrosion of rainwater, ultraviolet rays, high salt spray and other external environments, avoiding problems such as rust and aging on the outside of the frame due to long-term exposure, and providing a stable external protective barrier for the internal structure. At the same time, the cavity structure of the outer aluminum alloy frame 1 provides a precise installation space for the reinforcing rib assembly 2. Through the pre-set assembly slots on the inner side, it can be tightly fitted with the reinforcing rib assembly 2, ensuring that the force of the reinforcing rib assembly 2 can be evenly transferred to the outer frame, forming a cooperative load-bearing foundation of "outer frame - reinforcing rib".

[0028] The reinforcing rib assembly 2, installed inside the outer aluminum alloy frame 1, is the "core load-bearing reinforcement unit" of the entire structure. It constructs a two-way load-bearing support system through a three-layer nested structure of "outer reinforcing rib 201 - connector 202 - inner reinforcing rib 203". Both the outer reinforcing rib 201 and the inner reinforcing rib 203 are made of aluminum alloy, but are designed differently according to load requirements: the outer reinforcing rib 201 is 3-5 mm thick, bearing the main external loads such as wind pressure and external impacts. Its outer surface is coated with a 0.1-0.3 mm epoxy resin anti-corrosion coating, further enhancing the rib's corrosion resistance inside the frame and preventing rust caused by condensation and dust accumulation inside the frame, thus extending the rib's load-bearing stability; the inner reinforcing rib 203 is 2-3 mm thick, mainly bearing the torque and vertical tension generated when opening and closing doors and windows, such as the force transmission at hinges. Through a tight connection with the inner aluminum alloy frame 4, it distributes the internal load to the overall frame. The connector 202, which connects the outer reinforcing rib 201 and the inner reinforcing rib 203, is made of high-strength aluminum alloy. Its "Z"-shaped structure design has a unique stress buffering and dispersion effect: when the outer reinforcing rib 201 is subjected to lateral wind pressure, the "Z"-shaped bend can decompose the horizontal force into a component force perpendicular to the connector 202, which is transmitted to the inner reinforcing rib 203 through the evenly distributed welding points at both ends, avoiding single-point stress concentration; at the same time, the support gap formed by the "Z"-shaped structure in the vertical direction not only reserves installation space for the heat insulation layer 3, but also resists vertical deformation through its own rigidity. Combined with the thickness difference design between the outer reinforcing rib 201 and the inner reinforcing rib 203, the outer layer is thicker, which enhances the wind load resistance on the outside; the inner layer is slightly thinner, which takes into account both lightweight and internal stress. This makes the reinforcing rib assembly 2 significantly improve the torsional stiffness and bending strength compared with the traditional single reinforcing rib while reducing weight, effectively solving the problem of deformation and shaking of the door and window frame caused by uneven stress during long-term use.

[0029] The insulation layer 3, 5-10 mm thick and made of polyurethane foam, is fixedly connected to the side of the reinforcing rib assembly 2. It serves as a heat transfer barrier, forming a continuous insulation barrier by tightly filling the gap between the reinforcing rib assembly 2 and the inner aluminum alloy frame 4. The polyurethane foam has an extremely low thermal conductivity, effectively blocking the transfer of external heat through the metal conduction path of "outer frame - reinforcing rib - inner frame" during hot summers or cold winters. When the outside temperature is higher than the indoor temperature, the heat absorbed by the outer aluminum alloy frame 1 is blocked by the insulation layer 3 on the outside of the reinforcing rib assembly 2, preventing rapid heat conduction to the inner aluminum alloy frame 4. Conversely, in winter, indoor heat is also intercepted by the insulation layer 3, reducing heat loss through the metal structure. Simultaneously, the elastic properties of the insulation layer 3 fill the tiny gaps between the reinforcing rib assembly 2 and the inner aluminum alloy frame 4, enhancing the overall structural seal and buffering the thermal expansion and contraction of the metal caused by temperature changes, preventing abnormal noises or structural loosening due to changes in the gaps between frame components.

[0030] The inner aluminum alloy frame 4 serves as the "inner protection and force transmission terminal." Through its close connection with the inner reinforcing rib 203, it further disperses the force transmitted by the inner reinforcing rib 203 to the entire inner frame, while providing a stable installation base for door and window hardware such as locks and hinges. Its inner surface can be decorated according to decoration needs, taking into account both functionality and aesthetics. Together with the outer aluminum alloy frame 1, it forms the "inner and outer double protective shell" of the door and window frame. In conjunction with the middle reinforcing rib assembly 2 and the heat insulation layer 3, it forms a stable operating system that integrates "support-heat insulation-protection."

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
