Description

Technical Field

[0001] The invention relates to the technical field of repairing building curtain wall decoration materials, and in particular to a method for repairing honeycomb panels. Background Art

[0002] In high-quality, ultra-large-scale projects in the building curtain wall and decoration industries, metal honeycomb panels, thanks to their composite structure of inner and outer metal sheets and a honeycomb core, are a commonly used building material due to their high flatness, light weight, and ease of transportation and installation. However, over the long-term use of buildings, metal honeycomb panels frequently break, making repair difficult and costly.

[0003] The thin sheet material of the metal honeycomb panel's exterior is susceptible to damage from complex environmental factors and unexpected circumstances during a building's lifespan. For example, prolonged exposure to wind, sun, rain, and frost can cause the metal sheets to age and deform. Extreme weather conditions, such as hail and strong winds carrying foreign objects, can easily cause damage to the panels. Furthermore, accidental collisions and improper cleaning can also cause dents, scratches, and even perforations on the panel's surface.

[0004] Once a metal honeycomb panel is damaged during use, the currently common method of replacing it as a whole has many drawbacks. This not only requires repurchasing expensive new metal honeycomb panel materials, but also requires a significant investment of manpower and material resources for removal and installation, resulting in high repair costs. Summary of the Invention

[0005] In view of this, the present invention provides a honeycomb panel repair method to solve the problem of high repair cost after the metal honeycomb panel is damaged.

[0006] The present invention provides a honeycomb plate repair method, comprising the following steps:

[0007] Remove the original sealant between the damaged plate and the surrounding plates, expose the side of the damaged plate and clean the residual sealant on the side;

[0008] Clean the residue on the surface of the damaged plate and remove the convex part of the damaged part;

[0009] Grinding the outer surface of the damaged plate to a uniform rough surface;

[0010] Apply structural adhesive to the back of the replacement plate for repair;

[0011] Cover the replacement plate as a whole on the surface of the damaged plate, press the replacement plate as a whole, and then fix the replacement plate around the damaged plate;

[0012] The joints between the replacement plate and the surrounding plates are treated with sealant injection to restore them to their original state.

[0013] The above honeycomb panel repair method requires fixing and replacing the panel on the surface of the damaged panel. Therefore, it is necessary to first remove the original sealant between the damaged panel and the surrounding panels, and expose the side of the damaged panel. The side of the damaged panel is used to fix the replacement panel. In order to ensure the fixing effect, it is necessary to clean the residual glue on the side. Similarly, since it is necessary to fix and replace the panel on the surface of the damaged panel, after completing the above steps, it is also necessary to clean the dust, stains and other residues on the surface of the damaged panel, and further remove the protruding part of the damaged area until the surface is smooth. Then, in order to facilitate the bonding of the structural adhesive on the surface of the damaged panel, the outer surface of the damaged panel needs to be polished to a uniform rough surface to enhance the adhesion of the structural adhesive 5. Then, structural adhesive is applied to the back of the replacement panel to be used for repair. The replacement panel is then placed entirely over the surface of the damaged panel, pressed down, and then extended around the damaged panel to secure it. This secures the replacement panel to the surface of the damaged panel, repairing the damaged panel. Finally, sealant is injected around the joints between the replacement panel and the surrounding panels to restore the original appearance and waterproof performance of the curtain wall. This honeycomb panel repair method repairs damaged panels by placing a replacement panel entirely over the surface of the damaged panel. This repair method is convenient, easy, and relatively inexpensive. The appearance of the repaired panel is essentially the same as that of the surrounding panels, with a natural connection. Compared to replacing the damaged panel as a whole, it saves time and effort. The repair material is durable and not easily damaged or detached, reducing production costs.

[0014] In an optional embodiment, the step of removing the original sealant between the damaged plate and the surrounding plates, exposing the side of the damaged plate and cleaning the residual sealant on the side includes:

[0015] Use xylene solution to dissolve and remove the original sealant between the damaged plate and the surrounding plates and the residual glue on the side, then rinse and wipe it clean with clean water.

[0016] In an optional embodiment, the step of removing residues from the surface of the damaged plate and removing the convex portion of the damaged portion includes:

[0017] Use knocking or cutting tools to remove the protruding part of the damaged area.

[0018] In an optional embodiment, the step of grinding the entire outer surface of the damaged plate to a uniform rough surface includes:

[0019] The surface of the damaged plate is manually polished with 180-mesh sandpaper or polished with a 120-mesh handheld electric grinder, and the polishing thickness is less than or equal to 0.25 mm.

[0020] In an optional embodiment, the step of applying structural adhesive to the back of the replacement panel to be repaired includes:

[0021] The replacement plates used for repair are made of the same material with a thickness of 0-8mm-1.2mm.

[0022] In an optional embodiment, the step of applying structural adhesive to the back of the replacement panel to be repaired further includes:

[0023] The base structural adhesive should be applied along the four sides of the replacement plate with a width greater than or equal to 50mm and a thickness of 1mm-2mm, with air holes reserved at the corners; other areas should be applied using the point sticking method, with a diameter of the application dots greater than or equal to 80mm and adjacent spacing less than or equal to 200mm. The overall application area of the structural adhesive should be greater than or equal to 50% of the surface area of the replacement plate.

[0024] Applying a wide band of structural adhesive around the perimeter of the replacement panel creates an effective sealing barrier, preventing moisture, dust, and other impurities from entering the gap between the repaired area and the original panel. This prevents metal corrosion and adhesive failure caused by moisture intrusion, extending the service life of the repaired area. The edges of the replacement panel are subject to concentrated stress and are prone to warping and cracking. Applying a wider band of structural adhesive increases the bonding area and bond strength at the edges, ensuring a better bond between the replacement panel and the original panel and allowing them to withstand external forces. A width of 50mm or greater is required to ensure adequate sealing and bonding. During application, accurate measurement with a measuring tool is required to ensure the required application width is met. A graduated scraper or template can be used to assist in controlling the width. A suitable thickness range is 1mm-2mm. Too thin a band may not provide adequate bonding and sealing performance. Too thick a band not only increases costs but may also cause the adhesive to shrink and deform during curing, compromising bonding effectiveness. A thickness gauge can be used to monitor the thickness during application. The purpose of reserving vent holes at the corners is to expel the internal air during the curing process of the structural adhesive to avoid the formation of bubbles or hollows that affect the bonding quality. Figure 4 Shown in the lower middle part.

[0025] In an optional embodiment, the structural adhesive has a tensile bonding strength of 0.45 MPa-0.6 MPa, a maximum tensile strength of 100% elongation at 23° C., and a Shore hardness of 20 ShoreA-60 ShoreA.

[0026] In an optional embodiment, the step of covering the replacement plate as a whole on the surface of the damaged plate, pressing the replacement plate as a whole and then extending it around the damaged plate to fix the replacement plate includes:

[0027] Fold the replacement plate inwards on all sides, the inner diameter of the fold is greater than or equal to the outer diameter of the damaged plate by 2mm-3mm, the R corner radius is consistent with that of the damaged plate, and the fold size of the replacement plate is greater than or equal to 12mm.

[0028] In an optional embodiment, after the step of covering the entire surface of the damaged plate with the replacement plate, the method further includes:

[0029] The replacement plates are pressed sequentially from top to bottom, and the pressing roller is a rubber roller with a width greater than or equal to 150 mm.

[0030] In an optional embodiment, the step of fixing the replacement plate around the damaged plate after the overall pressing further includes:

[0031] After the replacement plate is covered with the damaged plate, self-tapping screws are used to fix it along the folded edges. The distance between the screws and the corners of the replacement plate is less than or equal to 80mm, and the screw spacing in the remaining parts is less than or equal to 300m.

[0032] The distance between the screws and the corners of the replacement panel is set to less than or equal to 80mm, mainly because corners are areas where the panel is subjected to complex forces and are prone to stress concentration. Placing screws within this distance effectively disperses the external forces exerted on the corners, enhancing the connection strength at the corners and preventing problems such as warping and cracking at the corners during use. The spacing between screws in the remaining areas is less than or equal to 300mm. This spacing setting ensures the overall fixing effect while reasonably controlling the number of screws used, balancing cost and structural strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] In high-quality, ultra-large-scale projects in the building curtain wall and decoration industries, metal honeycomb panels, thanks to their composite structure of inner and outer metal sheets and a honeycomb core, are a commonly used building material due to their high flatness, light weight, and ease of transportation and installation. However, over the long-term use of buildings, metal honeycomb panels frequently break, making repair difficult and costly.

[0047] The thin sheet material of the metal honeycomb panel's exterior is susceptible to damage from complex environmental factors and unexpected circumstances during a building's lifespan. For example, prolonged exposure to wind, sun, rain, and frost can cause the metal sheets to age and deform. Extreme weather conditions, such as hail and strong winds carrying foreign objects, can easily cause damage to the panels. Furthermore, accidental collisions and improper cleaning can also cause dents, scratches, and even perforations on the panel's surface.

[0048] If a metal honeycomb panel is damaged during use, the currently common method of replacing it entirely has numerous drawbacks. This not only requires repurchasing expensive new metal honeycomb panel materials, but also requires significant manpower and material resources for removal and installation, resulting in high repair costs. Therefore, this embodiment provides a honeycomb panel repair method to address these issues.

[0049] The following combination Figures 1 to 4 , describing embodiments of the present invention.

[0050] According to an embodiment of the present invention, a method for repairing a honeycomb plate is provided, comprising the following steps:

[0051] Remove the original sealant 3 between the damaged plate 1 and the surrounding plates 2, expose the side of the damaged plate 1 and clean the residual sealant on the side;

[0052] Remove the residue on the surface of the damaged plate 1 and remove the convex part of the damaged part;

[0053] Grind the entire outer surface of the damaged plate 1 to a uniform rough surface;

[0054] Apply structural adhesive 5 to the back of the replacement plate 4 to be repaired;

[0055] Place the replacement plate 4 on the surface of the damaged plate 1, press it down and then fix it around the damaged plate 1.

[0056] The joints between the replaced plate 4 and the surrounding plates 2 are treated with sealant injection to restore them to their original state.

[0057] The above honeycomb panel repair method requires fixing a replacement panel 4 on the surface of the damaged panel 1. Therefore, it is necessary to first remove the original sealant 3 between the damaged panel 1 and the surrounding panels 2, and expose the side of the damaged panel 1. The side of the damaged panel 1 is used to fix the replacement panel 4. In order to ensure the fixing effect, it is necessary to clean the residual glue on the side. Similarly, since it is necessary to fix a replacement panel 4 on the surface of the damaged panel 1, after completing the above steps, it is also necessary to clean the dust, stains and other residues on the surface of the damaged panel 1, and further remove the protruding part of the damaged area until the surface is smooth. Then, in order to facilitate the bonding of the structural adhesive 5 on the surface of the damaged panel 1, the outer surface of the damaged panel 1 needs to be polished to a uniform rough surface to enhance the adhesion of the structural adhesive 5. Then, the structural adhesive 5 is applied to the back of the replacement panel 4 to be used for repair, and the replacement panel 4 is completely covered on the surface of the damaged panel 1. After pressing the entire panel 4, the replacement panel 4 is extended around the damaged panel 1 to fix the replacement panel 4. Thus, the replacement panel 4 is fixed to the surface of the damaged panel 1 to repair the damaged panel 1. Finally, the joints between the replacement panel 4 and the surrounding panels 2 are treated with sealant injection to restore the original appearance and restore the appearance and waterproof performance of the curtain wall. This honeycomb panel repair method repairs the damaged panel 1 by using the replacement panel 4 to completely cover the surface of the damaged panel 1. This repair method is convenient and easy to implement, and the repair cost is relatively low. The appearance of the repaired panel is basically the same as that of the surrounding panels 2, and the connection is natural. Compared with replacing the damaged panel 1 as a whole, it saves time and effort. The repair material can be used for a long time and is not easy to be damaged or fall off, thereby reducing production costs.

[0058] In one embodiment, the steps of removing the original sealant 3 between the damaged panel 1 and the surrounding panels 2, exposing the side of the damaged panel 1 and cleaning the residual sealant on the side include:

[0059] Use xylene solution to dissolve and remove the original sealant 3 between the damaged plate 1 and the surrounding plates 2, as well as the residual glue on the side, and then rinse and wipe it clean with clean water.

[0060] When removing the original sealant 3 between the damaged plate 1 and the surrounding plates 2, use a brush dipped in xylene solution to evenly apply it on the surface of the original sealant 3. After it dissolves, use a scraper to thoroughly remove the old glue, leaving the sides of the damaged plate 1 exposed. Use fine sandpaper to clean the residual colloid on the sides, and finally rinse with clean water and wipe clean to ensure that there is no colloid residue on the sides.

[0061] In one embodiment, the step of removing residues from the surface of the damaged plate 1 and removing the convex portion of the damaged portion includes:

[0062] Use knocking or cutting tools to remove the protruding part of the damaged area.

[0063] In the above embodiments, striking or cutting tools are used to treat the protruding portion of the damaged area. The appropriate tool should be selected based on the damage condition, the material properties of the plate, and other factors, and standardized operating procedures should be strictly followed to ensure the best repair results. For smaller, less convex damage, a small striking tool, such as a machinist's hammer, is preferred. For larger and more sharply convex damage, a cutting tool, such as a handheld electric saw, is a more appropriate choice.

[0064] In one embodiment, the step of grinding the entire outer surface of the damaged plate 1 to a uniform rough surface includes:

[0065] The surface of the damaged plate 1 is manually polished with 180-grit sandpaper or polished with a 120-grit handheld electric grinder, and the polishing thickness is less than or equal to 0.25 mm.

[0066] When the damaged plate 1 is small in area, or the damage is located in a narrow, complex area, such as a corner or edge, where power tools are inconvenient, manual sanding is appropriate. For larger damaged plates 1, using an electric sander can greatly improve work efficiency. Electric sanders are suitable for damaged plates 1 with relatively flat and regular surfaces, quickly removing surface irregularities.

[0067] In one embodiment, the step of applying structural adhesive 5 to the back of the replacement panel 4 for repair includes:

[0068] The replacement plate 4 for repairing is made of the same material with a thickness of 0-8mm-1.2mm. Preferably, the replacement plate 4 for repairing is made of the same material with a thickness of 1mm.

[0069] In one embodiment, the step of applying structural adhesive 5 to the back of the replacement panel 4 for repair further includes:

[0070] The base structural adhesive 5 needs to be applied along the four sides of the replacement plate 4 with a width greater than or equal to 50mm and a thickness of 1mm-2mm, with ventilation holes reserved at the corners; other areas should be applied using the point sticking method, with a diameter of the application dots greater than or equal to 80mm and adjacent spacing less than or equal to 200mm. The overall application area of the structural adhesive 5 should be greater than or equal to 50% of the surface area of the replacement plate 4.

[0071] In the above embodiment, if Figure 4 As shown, applying a wide strip of structural adhesive 5 around the perimeter of the replacement panel 4 creates an effective sealing barrier, preventing impurities such as moisture and dust from entering the gap between the repaired area and the original panel. This prevents metal corrosion and structural adhesive 5 failure caused by moisture intrusion, thereby extending the service life of the repaired area. The edges of the replacement panel 4 are subject to concentrated forces and are prone to problems such as warping and cracking. Applying a wider strip of structural adhesive 5 increases the bonding area and bond strength at the edges, allowing the replacement panel 4 to better bond with the original panel and withstand external forces. A width of 50 mm or greater is required to ensure adequate sealing and bonding. During application, accurate measurements should be made using measuring tools to ensure the application width meets the requirements. A graduated scraper or template can be used to assist in controlling the width. A suitable thickness range is 1 mm to 2 mm. Too thin may not provide sufficient bonding and sealing performance. Too thick will not only increase costs but may also cause the structural adhesive 5 to shrink and deform during the curing process, affecting the bonding effect. A thickness gauge can be used to monitor the thickness during application. The purpose of reserving vent holes at the corners is to expel the internal air during the curing process of the structural adhesive 5 to avoid the formation of bubbles or hollows that affect the bonding quality. Figure 4 Shown in the lower middle part.

[0072] The point bonding method can make the structural adhesive 5 form dispersed bonding points between the replacement plate 4 and the original plate, avoiding stress concentration caused by large-area continuous bonding. When the structure is subjected to external force, these dispersed bonding points can better disperse the stress and improve the deformation resistance of the repaired part. Compared with the full coating method, the point bonding method can reduce the use of structural adhesive 5 and reduce costs while ensuring a certain bonding effect. The diameter of the smearing dots is greater than or equal to 80mm and the adjacent spacing is less than or equal to 200mm in order to ensure sufficient bonding area and bonding strength. The structural adhesive 5 of each dot should be applied evenly and with consistent thickness. You can use a glue gun or scraper to apply it to ensure that the structural adhesive 5 can be fully filled in the dot area and tightly combined with the replacement plate 4 and the original plate.

[0073] The entire coating area of the structural adhesive 5 is greater than or equal to 50% of the surface area of the replacement plate 4 in order to ensure that there is sufficient bonding area between the replacement plate 4 and the original plate, thereby providing sufficient bonding force and ensuring the stability and reliability of the repaired part.

[0074] In one embodiment, the structural adhesive 5 is a high-performance silicone structural sealant having a tensile bond strength of 0.45 MPa-0.6 MPa, preferably 0.5 MPa, a maximum tensile strength of 100% elongation at 23° C., and a Shore hardness of 20 Shore A-60 Shore A, preferably 40 Shore A.

[0075] In one embodiment, the step of covering the replacement plate 4 entirely on the surface of the damaged plate 1 and pressing the replacement plate 4 entirely to extend around the damaged plate 1 to fix the replacement plate 4 includes:

[0076] Fold the replacement plate 4 inward on all sides. The inner diameter of the fold is greater than or equal to the outer diameter of the damaged plate 1 by 2mm-3mm. The R corner radius is consistent with that of the damaged plate 1. The folding size of the replacement plate 4 is greater than or equal to 12mm.

[0077] In the above embodiment, the replacement plate 4 is folded inward on all sides, and the inner diameter of the fold is 2-3 mm greater than or equal to the outer diameter of the damaged plate 1. This size difference ensures that there is sufficient contact area and overlap between the replacement plate 4 and the damaged plate 1. When fixed with stainless steel self-tapping screws 6, a stable connection structure can be formed, effectively dispersing external forces, and preventing local stress concentration caused by a small connection area, which may cause the plate to fall off or loosen. In actual operation, taking a metal honeycomb panel of common specifications as an example, if the outer diameter of the damaged plate 1 is 1000 mm × 1000 mm, the inner diameter of the fold of the replacement plate 4 should be designed to be no less than 1002 mm × 1002 mm to ensure a tight and secure connection between the two after fixing. At the same time, this size design also facilitates positioning and operation by construction personnel during the installation process, and even if there are certain construction errors, the reliability of the connection can be guaranteed. The R corner radius of the replacement plate 4 is required to be consistent with that of the damaged plate 1, mainly to ensure consistency in appearance and overall coordination. The replacement plate 4's hem is designed to be greater than or equal to 12mm, primarily to meet the requirements of mechanical nailing and ensure structural strength. If the hem is too small, the self-tapping screws 6 will struggle to maintain sufficient anchoring force, which can lead to loosening and falling out, effectively preventing the replacement plate 4 from being secured. A hem of 12mm or greater provides ample space for the self-tapping screws 6 to penetrate, ensuring a reliable mechanical connection between the screw and the plate.

[0078] In one embodiment, after the step of covering the entire surface of the damaged plate 1 with the replacement plate 4, the method further comprises:

[0079] The replacement plate 4 is pressed sequentially from top to bottom, and the pressing roller is a rubber roller with a width greater than or equal to 150 mm.

[0080] Pressing the replacement plate 4 from top to bottom sequentially is to ensure that the replacement plate 4 fits tightly with the damaged plate 1, so that the structural adhesive 5 between the two is evenly distributed and fully in contact, thereby improving the bonding effect. Because the structural adhesive 5 can only effectively fill the gaps and eliminate bubbles to achieve the best bonding performance when it is evenly stressed. If the pressing is not standardized, it may cause the structural adhesive 5 to be unevenly distributed, and some areas may not be firmly bonded, affecting the strength and stability of the repaired plate. The selection of a rubber roller with a width greater than or equal to 150mm is mainly based on two considerations. On the one hand, a wider roller can cover a larger area at one time, ensuring the uniformity of the pressing and avoiding the situation where local pressing is not in place. When repairing a large area of metal honeycomb panels, a narrow roller needs to be repeated many times, which easily causes uneven pressing, while a wide roller can effectively solve this problem. On the other hand, the rubber roller has good elasticity and can buffer the pressure during the pressing process to avoid scratches, deformation and other damage to the outer surface of the metal honeycomb panel.

[0081] In one embodiment, after the overall pressing, the step of fixing the replacement plate 4 around the damaged plate 1 further includes:

[0082] After the replacement plate 4 is covered on the damaged plate 1, it is fixed with self-tapping screws 6 along the folded edges. The distance between the screws and the corners of the replacement plate 4 is less than or equal to 80 mm, and the screw spacing in the remaining parts is less than or equal to 300 mm.

[0083] The distance between the screws and the four corners of the replacement plate is set to less than or equal to 80mm, mainly because the corners are areas where the plate is subjected to complex forces and are prone to stress concentration. Placing screws within this distance effectively disperses the external forces on the corners, strengthens the connection strength at the corners, and prevents problems such as warping and cracking at the corners during use. The spacing between screws in the remaining areas is less than or equal to 300mm. This spacing setting ensures the overall fixing effect while reasonably controlling the number of screws used, balancing cost and structural strength.

[0084] The screws usually use ST3.5*16mm stainless steel self-tapping screws 6. Stainless steel has good corrosion resistance, can adapt to different use environments, and extend the service life of the repaired part.

[0085] Without replacing the original damaged panel (1), this method utilizes a complete overlay with the same surface material, based on the structural characteristics of the original panel. The new overlay is mechanically connected to the original panel using stainless steel screws and bonded with silicone structural adhesive (5). This repair method is convenient, easy to implement, and relatively inexpensive. The repaired panel and surrounding panels (2) appear essentially identical in appearance, with a seamless connection. Compared to replacing the damaged panel (1), this method saves time and effort. The repair material is durable and resistant to damage or shedding, reducing production costs.

[0086] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
