Description

Technical Field

[0001] This application relates to the field of aluminum panel technology, and in particular to an aluminum panel structure for curtain walls. Background Technology

[0002] In the field of modern architecture, curtain walls, as the external envelope of buildings, not only bear the functions of resisting the erosion of the natural environment and ensuring the safety and comfort of the interior space, but also become an important embodiment of architectural aesthetics with their unique appearance. Curtain walls come in various forms, including glass curtain walls, stone curtain walls, and metal curtain walls. Among them, metal curtain walls have been widely used in various types of buildings due to their many advantages such as being lightweight, high-strength, corrosion-resistant, and easy to process.

[0003] Aluminum single-panel panels, as one of the key materials for metal curtain walls, have unique advantages. They are made from aluminum alloy sheets as the base material, processed through sheet metal fabrication and surface treatment. Aluminum single-panel panels are relatively lightweight, which can effectively reduce the load on the building structure. They have high strength, which can meet the requirements of different building shapes and stresses. Moreover, aluminum single-panel panels have good weather resistance and corrosion resistance, and can be used for a long time under various harsh climatic conditions without significant performance degradation. With their excellent performance and beautiful appearance, they have become one of the preferred materials for curtain wall decoration.

[0004] In related technologies, if the joints between aluminum panels in existing aluminum single-panel structures are not properly sealed, rainwater can easily seep into the interior of the curtain wall. This can not only cause the insulation material inside the curtain wall to become damp and reduce its insulation performance, but may also corrode the keel and other metal components, affecting the service life of the curtain wall. Therefore, improvements are needed. Utility Model Content

[0005] To address the issue of poor sealing performance at the joints of aluminum panels, this application provides an aluminum panel structure for curtain walls.

[0006] The technical solution for an aluminum single-panel structure for curtain walls provided in this application is as follows: An aluminum single-panel structure for curtain walls includes a keel frame and several curtain wall units. The curtain wall units are sequentially installed on the keel frame. Each curtain wall unit includes four spliced ​​aluminum single-panel modules. The keel frame is cross-shaped. The intersection nodes of the keel frame are provided with longitudinal and transverse locking parts. The outer side of the curtain wall unit is provided with a vertical edge trim strip and two transverse edge trim strips. The vertical edge trim strip simultaneously connects with the adjacent sides of the four aluminum single-panel modules. The vertical edge trim strip is provided with a longitudinal positioning protrusion adapted to the longitudinal locking part of the keel frame. The two transverse edge trim strips are respectively provided on both sides of the vertical edge trim strip. Each transverse edge trim strip simultaneously connects with the adjacent sides of two adjacent aluminum single-panel modules. The transverse edge trim strip is provided with a transverse positioning protrusion adapted to the transverse locking part of the keel frame.

[0007] If the joints between aluminum panels in the existing aluminum panel structure are not properly sealed, rainwater can easily seep into the interior of the curtain wall. This can cause the insulation material inside the curtain wall to become damp, reducing its insulation performance, and may also corrode the keel and other metal components, affecting the service life of the curtain wall. By adopting the above technical solution, which includes a keel frame and several curtain wall units, the curtain wall units are installed sequentially on the keel frame. Each curtain wall unit is formed by splicing four aluminum panel modules. Longitudinal and transverse snap-fit ​​parts are installed at the intersection nodes of the keel frame. Vertical edge trim strips and two transverse edge trim strips are installed on the outside of the curtain wall units. The vertical edge trim strips are formed with longitudinal positioning protrusions, and the transverse edge trim strips are formed with transverse positioning protrusions. When assembling the curtain wall, the keel frame is pre-fixed to the building structure. Starting from one side of the installation area, the first insertion part of the inner edge of the aluminum panel module is aligned with the first connecting part already installed vertically on the keel. The aluminum panel module is then smoothly pushed towards the keel, ensuring the first insertion part is accurately inserted into the corresponding slot of the first connecting part. Following this method, other aluminum panel modules in the same row are installed longitudinally. After a row of aluminum panel modules is longitudinally positioned, the first horizontal connecting part is installed onto the first insertion part at the horizontal position of the inner edge of the aluminum panel module, ensuring a tight fit. The keel is then connected and fixed to the installed first horizontal connecting part. The installation of all aluminum panel modules is completed sequentially. After four aluminum panel modules in a certain area are spliced, the longitudinal positioning protrusion on the vertical edge strip is aligned with the keel frame. At the longitudinal snap-fit ​​part at the fork node, the vertical edge trim strip is simultaneously aligned with the adjacent sides of the four aluminum single-panel modules. The vertical edge trim strip is slowly pressed downwards so that its longitudinal positioning protrusion is fully snapped into the longitudinal snap-fit ​​part. At the same time, the second connecting part of the vertical edge trim strip is inserted and fixed with the second insertion part of the outer aluminum panel of each corresponding aluminum single-panel module to ensure a firm installation. After the vertical edge trim strip is installed, the two horizontal edge trim strips are hoisted to the corresponding positions on both sides of the vertical edge trim strip, so that the horizontal positioning protrusion on the horizontal edge trim strip is aligned with the horizontal snap-fit ​​part. The horizontal edge trim strip is aligned with the adjacent sides of the two adjacent aluminum single-panel modules. Similarly, the second connecting part of the horizontal edge trim strip is inserted and fixed with the second insertion part of the outer aluminum panel of each corresponding aluminum single-panel module to ensure a firm installation. Sealing strips are then inserted into the gap between the outer and inner aluminum panels of the aluminum single-panel module. Finally, the protective cover is sequentially embedded on the outside of the vertical edge trim strip and the horizontal edge trim strip to complete the assembly. By setting up the keel frame and curtain wall units, and utilizing the interlocking cooperation between the keel frame and the vertical and horizontal edge strips on the outside of the curtain wall units, the sealing performance at the splicing points of the aluminum single-panel modules is enhanced, forming a waterproof barrier. This effectively prevents rainwater from seeping into the interior of the curtain wall along the splicing seams, thereby reducing the thermal insulation performance degradation caused by moisture in the insulation material and the structural strength reduction caused by long-term corrosion of metal components such as the keel. This ensures the overall thermal insulation performance of the curtain wall and extends its service life.

[0008] Optionally, the aluminum panel module has a double-layer structure, comprising an outer aluminum panel and an inner aluminum panel.

[0009] By adopting the above technical solution, the aluminum single-panel module has a double-layer structure, which includes an outer aluminum panel and an inner aluminum panel. Through the setting of the outer and inner aluminum panels, the double-layer structure forms an impact-resistant protection through the outer aluminum panel, effectively resisting wind pressure and mechanical damage in the external environment. At the same time, the inner aluminum panel serves as a structural support, working together with the outer panel to enhance the overall rigidity and deformation resistance of the aluminum single-panel module and extend the service life of the curtain wall.

[0010] Optionally, a sealing strip is provided at the gap between the outer aluminum panel and the inner aluminum panel of the aluminum single panel module, and the sealing strip is arranged along the circumferential direction of the aluminum single panel module.

[0011] By adopting the above technical solution, the sealing strip is inserted into the gap between the outer and inner aluminum panels; the sealing strip effectively fills the gap between the two layers, blocking external media such as rainwater and dust from seeping through the splicing gap, thus improving the waterproof sealing of the curtain wall.

[0012] Optionally, the inner edge of the aluminum panel of the aluminum single panel module is provided with a first plug-in part, and the longitudinal and transverse positions of the keel frame are respectively provided with first connecting parts, and the first connecting parts are plugged into the corresponding first plug-in parts.

[0013] By adopting the above technical solution, the first plug-in part is installed on the inner edge of the aluminum panel of the aluminum single panel module, and the first connecting part is installed on the longitudinal and transverse positions of the keel frame. Through the setting of the first plug-in part and the first connecting part, the aluminum single panel module is mechanically and firmly fixed to the keel frame, realizing the efficient assembly between the curtain wall unit and the keel frame.

[0014] Optionally, the outer edge of the aluminum panel of the aluminum single panel module is provided with a second insertion part, and the vertical edge trim and the two horizontal edge trims are respectively provided with a second connecting part, and the second connecting part is inserted and engaged with the corresponding first insertion part.

[0015] By adopting the above technical solution, the second plug-in part is installed on the outer edge of the aluminum panel of the aluminum single panel module, and the second connecting part is installed on the vertical edge trim and the two horizontal edge trims; through the setting of the second plug-in part and the second connecting part, the edge trim is connected to the outer edge of the aluminum single panel through mechanical interlocking, realizing the efficient assembly of the curtain wall unit with the vertical edge trim and the horizontal edge trim.

[0016] Optionally, both the first and second insertion parts are male tenons, and the mating sides of the first and second connecting parts are female tenons that match the male tenons.

[0017] By adopting the above technical solution, both the first and second insertion parts are male tenons, and the first and second connecting parts are female tenons. Through the design of the shapes of the insertion parts and connecting parts, the tenon and mortise joint enables the rapid assembly between the aluminum single panel module and the keel frame and edge strip, and improves the stability of the splice.

[0018] Optionally, a protective cover is provided on the outer side of the vertical edge strip and the two horizontal edge strips, and an accommodating cavity is formed inside the protective cover for embedding the vertical edge strip or the horizontal edge strip.

[0019] By adopting the above technical solution, protective covers are installed on the outside of the vertical edge trim strip and the two horizontal edge trim strips. The protective covers effectively block rainwater, dust and ultraviolet rays from directly corroding the connection parts of the edge trim strips, extending their service life. At the same time, the rigid outer shell of the protective covers can disperse external impact forces and prevent the edge trim strips from deforming or falling off due to mechanical collisions.

[0020] Optionally, the accommodating cavity of the protective cover is provided with limiting ribs for restricting the position of the corresponding vertical or horizontal edge strips.

[0021] By adopting the above technical solution, the limiting rib is formed in the cavity of the protective cover; by setting the limiting rib, the limiting rib ensures the assembly accuracy of the edge strip and the cover, and prevents the edge strip from shifting and falling off under wind pressure or vibration conditions.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up the keel frame and curtain wall units, and utilizing the interlocking cooperation between the keel frame and the vertical and horizontal edge strips on the outside of the curtain wall units, the sealing performance at the splicing points of the aluminum single panel modules is enhanced, forming a waterproof barrier. This effectively prevents rainwater from seeping into the interior of the curtain wall along the splicing seams, thereby reducing the thermal insulation performance degradation caused by moisture in the insulation material and the structural strength reduction caused by long-term corrosion of metal components such as the keel. This ensures the overall thermal insulation performance of the curtain wall and extends its service life. 2. By setting up outer and inner aluminum panels, the double-layer structure forms impact protection through the outer aluminum panels, effectively resisting wind pressure and mechanical damage in the external environment. At the same time, the inner aluminum panels serve as structural support, working together with the outer panels to enhance the overall rigidity and deformation resistance of the aluminum single panel module and extend the service life of the curtain wall. 3. The protective cover effectively blocks rainwater, dust, and ultraviolet rays from directly eroding the joints of the edge trim, extending its service life. At the same time, the rigid outer shell of the protective cover can disperse external impact forces, preventing the edge trim from deforming or falling off due to mechanical collisions.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses an aluminum single-panel structure for curtain walls. (Refer to...) Figure 1 The aluminum single-panel structure for the curtain wall includes a keel frame 1 and several curtain wall units 2. The keel frame 1 is fixedly installed on the building structure. In this embodiment, the keel frame 1 is cross-shaped, and several curtain wall units 2 are sequentially spliced ​​and installed on the keel frame 1 to form a curtain wall structure.

[0030] Reference Figure 1Each curtain wall unit 2 includes four aluminum single panel modules 21, which are spliced ​​together. In this embodiment, the aluminum single panel module 21 has a double-layer structure, including an outer aluminum panel 201 and an inner aluminum panel 202. The double-layer structure forms an impact-resistant protection through the outer aluminum panel 201, effectively resisting wind pressure and mechanical damage in the external environment. At the same time, the inner aluminum panel 202 serves as a structural support, working together with the outer panel to enhance the overall rigidity and deformation resistance of the aluminum single panel module 21, and extend the service life of the curtain wall.

[0031] Reference Figure 1 and Figure 2 A sealing strip 7 is provided at the gap between the outer aluminum panel 201 and the inner aluminum panel 202 of the aluminum single panel module 21. The sealing strip 7 is arranged along the circumferential direction of the aluminum single panel module 21. The sealing strip 7 effectively fills the gap between the two layers and blocks the penetration channels of external media such as rainwater and dust through the splicing gap, thereby improving the waterproof sealing of the curtain wall. In this embodiment, corresponding sealing strips 7 are also installed between adjacent curtain wall units 2.

[0032] Reference Figure 3 and Figure 4 The inner edge of the aluminum panel 202 of the aluminum single panel module 21 is provided with a first plug-in part 8. There are two first plug-in parts 8, which are located in the longitudinal and transverse positions of the inner aluminum panel 202, respectively. The longitudinal and transverse positions of the keel frame 1 are respectively provided with a first connecting part 9, which is plugged into the corresponding first plug-in part 8. This allows the aluminum single panel module 21 to be mechanically engaged and stabilized in the keel frame 1, thus achieving efficient assembly between the curtain wall unit 2 and the keel frame 1.

[0033] Reference Figure 1 and Figure 4 At the intersection of the keel frame 1, longitudinal snap-fit ​​parts 3 and transverse snap-fit ​​parts 4 are installed. On the outside of the curtain wall unit 2, vertical edge trim strips 5 and two transverse edge trim strips 6 are installed. The vertical edge trim strips 5 simultaneously connect with the adjacent sides of the four aluminum single panel modules 21. The vertical edge trim strips 5 are equipped with longitudinal positioning protrusions 51 that are compatible with the longitudinal snap-fit ​​parts 3 of the keel frame 1. The two transverse edge trim strips 6 are respectively set on both sides of the vertical edge trim strips 5. Each transverse edge trim strip 6 simultaneously connects with the adjacent sides of the two adjacent aluminum single panel modules 21. The transverse edge trim strips 6 are equipped with transverse positioning protrusions 61 that are compatible with the transverse snap-fit ​​parts 4 of the keel frame 1.

[0034] Reference Figure 4The outer aluminum panel 201 edge of the aluminum single panel module 21 is equipped with a second plug-in part 10. There are two second plug-in parts 10. The two first plug-in parts 8 are located in the longitudinal and transverse positions of the outer aluminum panel 201, respectively. The vertical edge trim 5 and the two transverse edge trims 6 are equipped with corresponding second connecting parts 11. The second connecting parts 11 are plugged into the corresponding first plug-in parts 8. The edge trims are mechanically engaged with the outer edge of the aluminum single panel, realizing the efficient assembly of the curtain wall unit 2 with the vertical edge trim 5 and the transverse edge trim 6.

[0035] Reference Figure 4 In this embodiment, both the first insertion part 8 and the second insertion part 10 are male tenons, and the mating side of the first connecting part 9 and the second connecting part 11 is a female tenon that matches the male tenon; the tenon and mortise joint realizes the rapid assembly between the aluminum single panel module 21 and the keel frame 1 and the edge strip, and improves the stability of the splice.

[0036] Reference Figure 4 The vertical edge strip 5 and the two horizontal edge strips 6 are all equipped with protective covers 12. The protective covers 12 have accommodating cavities for embedding the vertical edge strip 5 or the horizontal edge strip 6. By shielding, they effectively block rainwater, dust and ultraviolet rays from directly corroding the connection parts of the edge strips, thus extending their service life. At the same time, the rigid outer shell of the protective covers 12 can disperse external impact forces and prevent the edge strips from deforming or falling off due to mechanical collisions.

[0037] Reference Figure 4 The protective cover 12 has a limiting rib 13 formed in its accommodating cavity. The limiting rib 13 ensures the assembly accuracy of the edge strip and the cover, and prevents the edge strip from displacing and falling off under wind pressure or vibration conditions.

[0038] The implementation principle of an aluminum single-panel structure for curtain walls in this application embodiment is as follows: When assembling the curtain wall, the keel frame 1 is pre-fixed to the building structure. Starting from one side of the installation area, the first insertion part 8 of the inner edge of the aluminum panel 202 of the aluminum single-panel module 21 is aligned with the first connecting part 9 of the vertical position already installed on the keel. The aluminum single-panel module 21 is then steadily pushed towards the keel so that the first insertion part 8 is accurately inserted into the corresponding slot of the first connecting part 9. Following the above method, other aluminum single-panel modules 21 in the same row are then installed longitudinally. For the plug-in installation, after the longitudinal plug-in positioning of a row of aluminum panel modules 21 is completed, the first transverse connecting part 9 is installed onto the first plug-in part 8 at the transverse position of the edge of the aluminum panel 202 inside the aluminum panel module 21, ensuring that it fits tightly with the first transverse plug-in part 8 of the aluminum panel module 21. The keel is then connected and fixed to the installed first transverse connecting part 9. The installation of all aluminum panel modules 21 is completed in sequence. After the four aluminum panel modules 21 in a certain area are spliced, the longitudinal positioning protrusion 51 on the vertical edge strip 5 is aligned with the keel frame. At the longitudinal snap-fit ​​part 3 at the intersection of frame 1, the vertical edge trim 5 is simultaneously aligned with the adjacent sides of the four aluminum single-panel modules 21. The vertical edge trim 5 is slowly pressed downwards until its longitudinal positioning protrusion 51 is fully engaged with the longitudinal snap-fit ​​part 3. Simultaneously, the second connecting part 11 of the vertical edge trim 5 is inserted and fixed to the second insertion part 10 of the outer aluminum panel 201 of each corresponding aluminum single-panel module 21, ensuring a secure installation. After the vertical edge trim 5 is installed, the two horizontal edge trims 6 are respectively hoisted to their corresponding positions on both sides of the vertical edge trim 5, allowing the horizontal edge trims to be properly positioned. The horizontal positioning protrusion 61 on the edge strip 6 is aligned with the horizontal snap-fit ​​part 4. The horizontal edge strip 6 is connected to the adjacent side of the two adjacent aluminum single panel modules 21. Similarly, the second connecting part 11 of the horizontal edge strip 6 is inserted and fixed to the second insertion part 10 of the outer aluminum panel 201 of the corresponding aluminum single panel module 21 to ensure a firm installation. A sealing strip 7 is then inserted into the gap between the outer aluminum panel 201 and the inner aluminum panel 202 of the aluminum single panel module 21. Finally, the protective cover 12 is sequentially embedded on the outside of the vertical edge strip 5 and the horizontal edge strip 6 to complete the assembly. By setting up the keel frame 1 and the curtain wall unit 2, and utilizing the interlocking cooperation between the keel frame 1 and the outer vertical edge strip 5 and horizontal edge strip 6 of the curtain wall unit 2, the sealing performance at the splicing point of the aluminum single panel module 21 is enhanced, forming a waterproof barrier. This effectively prevents rainwater from seeping into the interior of the curtain wall along the splicing seam, thereby reducing the thermal insulation performance degradation caused by moisture in the insulation material and the structural strength reduction caused by long-term corrosion of metal components such as the keel. This ensures the overall thermal insulation performance of the curtain wall and extends its service life.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
