Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile technology, specifically a high-strength aluminum alloy profile for a combined energy-saving curtain wall. Background Technology

[0002] A modular energy-saving curtain wall is a type of building curtain wall composed of panels made of different materials, such as glass, metal, and stone slabs, offering multiple functions and advantages. Its components include unit columns, small decorative strips, large decorative strip splicing profiles, stainless steel screws, concealed frame edge protection profiles, decorative strip adapters, sealing strips, and glass panels. An energy-saving curtain wall is a building's external cladding structure, composed of metal structures and panels, possessing a certain degree of displacement relative to the main structure or its own deformation capacity, but it does not bear the load or action of the main structure. Its main functions include aesthetics, thermal insulation, waterproofing, and sound insulation.

[0003] Currently, aluminum alloy profiles used in modular energy-saving curtain walls may have insufficient strength in certain specific application scenarios, especially in curtain wall systems with large spans, high wind pressure, or complex shapes. Furthermore, traditional aluminum alloy profiles are mostly single-cavity designs, which are prone to deformation when subjected to large loads. Therefore, we propose a high-strength aluminum alloy profile for modular energy-saving curtain walls. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength aluminum alloy profile for modular energy-saving curtain walls, which has the advantages of high strength and large load-bearing capacity. It solves the problem that aluminum alloy profiles used in modular energy-saving curtain walls may have insufficient strength in certain specific application scenarios, especially in curtain wall systems with large spans, high wind pressure or complex shapes. In addition, traditional aluminum alloy profiles are mostly single-cavity designs, which are prone to deformation when subjected to large loads.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength aluminum alloy profile for a combined energy-saving curtain wall, comprising:

[0006] The column has multiple equidistant ribs on its inner side, and ribs are arranged around the ribs.

[0007] The crossbeams located on the front and rear sides of the column have a fixing cylinder on the inner side of the crossbeam. Reinforcing fins are fixedly connected between the outer surface of the fixing cylinder and the inner wall of the crossbeam. A connection socket is provided at one end of the crossbeam.

[0008] A connector that is fixedly installed on both the front and rear sides of the column and is compatible with the connector socket;

[0009] A honeycomb fiber braided layer is bonded to the surface of the columns and beams, and the outer side of the honeycomb fiber braided layer is coated with a glass fiber reinforced polyurethane coating.

[0010] Preferably, a connecting cover plate is fixedly installed on the left side of the column by connecting screws, and a decorative cover plate is fastened to the left end of the connecting cover plate.

[0011] Preferably, the top and bottom of the crossbeam are provided with tempered glass.

[0012] Preferably, a sealing strip is provided between the tempered glass and the column and the connecting cover plate.

[0013] Preferably, the honeycomb fiber braided layer is made of carbon fiber braided layer.

[0014] Preferably, the inner wall of the crossbeam is provided with a plurality of equally spaced rectangular toothed protrusions.

[0015] Preferably, the column, ribs, and ribs are integrally formed, and the ribs and ribs cooperate to form multiple identical cavity structures on the inner side of the column.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up ribs and ribs, this utility model can enhance the internal strength of the column while dividing the inside of the column into multiple identical cavity structures, thus ensuring the strength of the column during use. By setting up the fixing cylinder and reinforcing fins, the inside of the crossbeam can be divided into cylindrical cavities with four identical cavity structures, thereby ensuring the internal strength of the crossbeam and avoiding the setting of a single cavity.

[0018] 2. The honeycomb fiber braided layer of this utility model, with the assistance of the carbon fiber braided layer, gives the columns and beams high external strength and rigidity. The honeycomb braided structure can effectively distribute the load, enhancing the bending, shearing, and compressive strength of the entire profile structure. The glass fiber reinforced polyurethane coating further enhances the external strength of the columns and beams. The glass fiber reinforced polyurethane coating can contact the external surface of the columns and beams through the honeycomb gaps of the honeycomb fiber braided layer. While enhancing the adhesion strength of the glass fiber reinforced polyurethane coating, the honeycomb fiber braided layer can further improve the surface strength of the columns and beams, achieving a performance improvement greater than the sum of its parts. As a result, the aluminum alloy profiles used in this combined energy-saving curtain wall can meet the requirements of large loads. Attached Figure Description

[0028] Example 1

[0029] Please see Figures 1-4 As shown, this utility model provides a technical solution: a high-strength aluminum alloy profile for a combined energy-saving curtain wall, comprising:

[0030] The column 1 has multiple equidistant ribs 101 on its inner side, and ribs 102 are provided around the ribs 101.

[0031] The crossbeams 2 are located on the front and rear sides of the column 1. A fixing cylinder 202 is provided on the inner side of the crossbeam 2. Reinforcing fins 201 are fixedly connected between the outer surface of the fixing cylinder 202 and the inner wall of the crossbeam 2. A connecting socket 204 is provided at one end of the crossbeam 2.

[0032] Connecting base 3, which is fixedly installed on the front and rear sides of the column 1 and is compatible with the connecting socket 204;

[0033] A honeycomb fiber braided layer 4 is bonded to the surface of the column 1 and the beam 2, and the outer side of the honeycomb fiber braided layer 4 is coated with a glass fiber reinforced polyurethane coating 5.

[0034] A connecting cover plate 105 is fixedly installed on the left side of the column 1 by connecting screws 107. A decorative cover plate 106 is fastened to the left end of the connecting cover plate 105. Tempered glass 104 is provided at the top and bottom of the crossbeam 2. A sealing strip 103 is provided between the tempered glass 104, the column 1 and the connecting cover plate 105. The honeycomb fiber braided layer 4 is made of carbon fiber braided layer. The column 1, the rib 101 and the rib 102 are integrally formed structures, and the cooperation between the rib 101 and the rib 102 forms multiple identical cavity structures on the inner side of the column 1.

[0035] This technical solution involves installing the connecting base 3 on both sides of the column 1, allowing the connecting socket 204 to mate with the connecting base 3. Next, the connecting cover plate 105 is installed on the left side of the column 1 using connecting screws 107, and the decorative cover plate 106 is fastened to the left end of the connecting cover plate 105. Simultaneously, with the assistance of the sealing strip 103, the tempered glass 104 can be assembled. Furthermore, the ribs 101 and ribs 102 enhance the internal strength of the column 1 while dividing its interior into multiple identical cavity structures, ensuring the column's stability. The strength of column 1 during use is ensured by the arrangement of the fixing cylinder 202 and the reinforcing fins 201, which divide the interior of beam 2 into four identical cylindrical cavities, thus guaranteeing the internal strength of beam 2. The honeycomb fiber braided layer 4, with the assistance of the carbon fiber braided layer, gives both column 1 and beam 2 high external strength and rigidity. Furthermore, the honeycomb braided structure effectively distributes the load, enhancing the bending, shear, and compressive strength of the entire profile structure. Since carbon fiber has a much lower density than metal, the honeycomb braided layer can significantly reduce its density. The composite structure's weight is reduced, and the material's specific strength and specific stiffness are improved. Simultaneously, carbon fiber itself has excellent corrosion resistance, protecting the internal aluminum profiles from environmental erosion. Furthermore, carbon fiber exhibits good thermal stability, maintaining performance even at high temperatures, thus enhancing the composite structure's high-temperature resistance. The honeycomb structure also provides good heat and sound insulation, reducing heat and sound transmission. Moreover, the honeycomb structure can be designed in different shapes and densities to adapt to various application scenarios and performance requirements. The addition of a glass fiber reinforced polyurethane coating 5 further enhances the external strength of the columns 1 and beams 2. The glass fiber reinforced polyurethane coating 5 can also contact the exterior of the columns 1 and beams 2 through the honeycomb gaps of the honeycomb fiber braided layer 4. This enhances the adhesion strength of the glass fiber reinforced polyurethane coating 5, and together with the honeycomb fiber braided layer 4, further improves the surface strength of the columns 1 and beams 2, achieving a performance improvement greater than the sum of its parts. This ensures that the aluminum alloy profiles used in this combined energy-saving curtain wall can withstand larger loads and avoids the need for a single cavity design.

[0037] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the inner wall of the crossbeam 2 is provided with multiple equally spaced rectangular toothed protrusions 203.

[0038] This technical solution: By setting the rectangular toothed ribs 203, the inner wall strength of the crossbeam 2 can be further enhanced, thus improving the applicability of the combined energy-saving curtain wall.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
