Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a corrosion-resistant perforated panel for building curtain walls. Background Technology

[0002] Perforated panels for building curtain walls are a type of sheet material with a special perforation design used in building curtain walls. They are architectural decorative materials made by perforating metal sheets, aluminum sheets, stainless steel sheets, etc., according to certain rules and design requirements. They are typically used as the outer surface layer of building curtain walls, serving functions such as decoration, sun shading, and ventilation. They generally consist of panels, framing, and connecting components. The panels are the perforated panels themselves, with different materials, thicknesses, and perforation patterns selected according to design requirements. The framing supports the panels, ensuring their flatness and stability, and is usually made of aluminum alloy or steel. The connecting components connect the panels to the framing, and the framing to the main structure.

[0003] Currently, in the use of perforated panels for building curtain walls, the panels are exposed to the outside of the building for a long time, and are easily corroded by rainwater and ultraviolet rays, which can lead to rust on the surface of the perforated panels. This not only reduces their service life, but also affects the aesthetics of the building curtain wall and causes certain inconveniences. In addition, during the installation process, existing perforated panels for building curtain walls are mostly fixed directly to the curtain wall keel through fixed brackets. This installation method makes it difficult to fine-tune the position of the perforated panels, resulting in the perforated panels being difficult to align vertically, horizontally, and vertically, which also causes certain inconveniences.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A corrosion-resistant perforated panel for building curtain walls includes a perforated panel mechanism. A fixing mechanism is provided on one side of the perforated panel mechanism. The perforated panel mechanism includes a sheet material. A fixing member is fixedly connected to one side of the sheet material. An adjustment hole is provided inside the fixing member. A through hole is provided on the surface of the sheet material.

[0007] A further improvement of the present invention is that the plate includes a base layer, and the surface of the base layer is coated with a base layer coating.

[0008] A further improvement of this utility model is that: the surface of the bottom coating is sprayed with a middle coating, and the surface of the middle coating is sprayed with a top coating.

[0009] A further improvement of the present invention is that the fixing mechanism includes a fixing nail, and a fixing plate is provided on the surface of one end of the fixing nail.

[0010] A further improvement of this utility model is that an adjusting slide rail is fixedly connected to the middle of one side of the fixed plate, and a sliding sleeve is slidably connected to the surface of the adjusting slide rail.

[0011] A further improvement of this utility model is that: a fixing screw is internally threaded onto the sliding sleeve, one end of the fixing screw abuts against the surface of the adjusting slide rail, a connecting plate is fixedly connected to the surface of the sliding sleeve, the top of one end of the connecting plate overlaps with the bottom of the fixing member, and an installation bolt is provided inside the connecting plate.

[0012] A further improvement of this utility model is that the base layer is made of aluminum alloy and the bottom coating is made of epoxy zinc-rich primer.

[0013] A further improvement of this utility model is that the intermediate coating is a polyurethane coating and the top coating is a fluorocarbon coating.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a corrosion-resistant perforated panel for building curtain walls. It features a base coating, a middle coating, and a top coating on the panel surface. The base coating is an epoxy zinc-rich primer with a high zinc powder content, providing cathodic protection to the substrate. In the event of localized damage such as scratches, the zinc powder preferentially corrodes, delaying rusting of the base layer. The middle coating is a polyurethane coating, possessing good flexibility and filling properties, capable of filling minor defects on the panel surface, and exhibiting good adhesion to both the base and top coatings. The top coating is a fluorocarbon coating; fluorocarbon resin has low surface energy and high weather resistance, effectively resisting erosion from ultraviolet rays, acid rain, and salt spray, making it more corrosion-resistant and preventing rusting of the perforated panel surface. Furthermore, during installation, the panel's left, right, up, and down positions can be finely adjusted via adjustable rails and holes, making it easier to align with other perforated panels and facilitating use.

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model provides a corrosion-resistant perforated panel for building curtain walls, including a perforated panel mechanism. A fixing mechanism is provided on one side of the perforated panel mechanism. The perforated panel mechanism includes a plate 11. A fixing member 12 is fixedly connected to one side of the plate 11. An adjustment hole 13 is opened inside the fixing member 12. A through hole 14 is opened on the surface of the plate 11. The plate 11 includes a base layer 111. A base layer coating 112 is sprayed on the surface of the base layer 111. A middle layer coating 113 is sprayed on the surface of the base layer coating 112. A top layer coating 114 is sprayed on the surface of the middle layer coating 113. The base layer 111 is made of aluminum alloy. The base layer coating 112 is made of epoxy zinc-rich primer. The middle layer coating 113 is made of polyurethane coating. The top layer coating 114 is made of fluorocarbon coating.

[0024] In this embodiment, the bottom coating 112 is an epoxy zinc-rich primer with a high zinc powder content, which can provide cathodic protection for the substrate. In the event of localized damage such as scratches on the plate, the zinc powder will preferentially corrode, delaying the rusting of the base layer. The middle coating 113 is a polyurethane coating, which has good flexibility and filling properties, and can fill the minor defects on the surface of the base layer 111. At the same time, it has good adhesion to both the bottom coating 112 and the top coating 114. The top coating 114 is a fluorocarbon coating. Fluorocarbon resin has low surface energy and high weather resistance, which can effectively resist the corrosion of ultraviolet rays, acid rain, salt spray, etc., making it more corrosion resistant, preventing the surface of the perforated plate from rusting, and extending its service life.

[0025] Example 2

[0026] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the fixing mechanism includes a fixing nail 21, a fixing plate 22 is provided on the surface of one end of the fixing nail 21, an adjusting slide rail 23 is fixedly connected to the middle of one side of the fixing plate 22, and a sliding sleeve 24 is slidably connected to the surface of the adjusting slide rail 23.

[0027] In this embodiment, during use, the fixing plate 22 is fixed to the building curtain wall by connecting the fixing nail 21 to the keel in the building curtain wall. When installing the panel 11, the sliding sleeve 24 can be pushed to slide along the adjusting slide rail 23 to make fine adjustments to the upper and lower positions of the panel 11. After adjusting to the appropriate position, the fixing screw 26 is rotated so that one end of it is tightly pressed against the surface of the adjusting slide rail 23, thereby fixing the upper and lower positions of the panel 11.

[0028] Example 3

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the sliding sleeve 24 is internally threaded with a fixing screw 26, one end of the fixing screw 26 abuts against the surface of the adjusting slide rail 23, the surface of the sliding sleeve 24 is fixedly connected with a connecting plate 25, the top of one end of the connecting plate 25 overlaps with the bottom of the fixing member 12, and the connecting plate 25 is internally provided with an installation bolt 27.

[0030] In this embodiment, by loosening the mounting bolt 27 and pushing the fixing member 12, the mounting bolt 27 can slide within the adjustment hole 13, thereby adjusting the left and right position of the plate 11. After adjustment, tightening the mounting bolt 27 completes the adjustment of the left and right position of the plate 11, making it easier to align with the surrounding perforated plates.

[0031] The working principle of this corrosion-resistant perforated panel for building curtain walls will be explained in detail below.

[0032] like Figure 1-4As shown, during use, the fixing plate 22 is fixed to the building curtain wall by connecting the fixing nail 21 to the keel in the building curtain wall. When installing the panel 11, the sliding sleeve 24 can be pushed to slide along the adjusting slide rail 23 to finely adjust the vertical position of the panel 11. After adjusting to the appropriate position, the fixing screw 26 is rotated so that one end of it is tightly pressed against the surface of the adjusting slide rail 23, thus fixing the vertical position of the panel 11. Then, the mounting bolt 27 is loosened, and the fixing part 12 is pushed so that the mounting bolt 27 slides in the adjusting hole 13, thus adjusting the horizontal position of the panel 11. After adjustment, the mounting bolt 27 is tightened to complete the adjustment of the horizontal position of the panel 11. The adjustment makes it easier to align with the surrounding perforated plates. Meanwhile, the bottom coating 112 uses an epoxy zinc-rich primer with a high zinc powder content, which can provide cathodic protection for the substrate. In the event of local damage such as scratches on the plate, the zinc powder will preferentially corrode, delaying the rusting of the base layer. The middle coating 113 is a polyurethane coating with good flexibility and filling properties, which can fill the minor defects on the surface of the base layer 111. It also has good adhesion to both the bottom coating 112 and the top coating 114. The top coating 114 uses a fluorocarbon coating. Fluorocarbon resin has low surface energy and high weather resistance, which can effectively resist the corrosion of ultraviolet rays, acid rain, salt spray and other corrosive substances, making it more corrosion resistant, preventing the surface of the perforated plate from rusting and extending its service life.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
