[0002] Curtain walls are lightweight, decorative structures commonly used in modern large and high-rise buildings, often serving as exterior enclosures. Curtain walls primarily consist of panels and supporting structures. Panels can be made of glass, metal, stone, ceramic, and other materials. Panel styles range from traditional flat panels to curved and other complex shapes, resulting in an increasingly diverse range of designs.

[0003] Metal plate surface materials, especially aluminum plates, are widely used in curtain walls because of their advantages of being waterproof, anti-fouling and anti-corrosion, and being relatively easy to process, transport, install and construct. In order to enhance the strength of the panel and avoid deformation during long-term use, reinforcing ribs need to be provided behind the metal panel. In the prior art, for curved metal plate curtain walls, the processing and assembly of reinforcing ribs are very time-consuming and labor-intensive. Currently, the industry mainly produces reinforcing ribs that are close to the curvature of the metal panel by bending the profile, and then connects them to the metal panel by welding nails and structural adhesives. However, the process of bending the profile is difficult and costly, and the bent reinforcing ribs have poor fit to the curved surface of the metal panel, low matching accuracy, and are difficult to install, which urgently needs to be improved.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following embodiments and accompanying drawings specifically illustrate the metal curtain wall panel reinforcement structure of the present invention.

[0031] Example 1

[0032] Figure 1 is a cross-sectional view of the metal curtain wall panel and the metal curtain wall panel reinforcement structure, the cross-section being perpendicular to the main exterior wall of the building on which it is installed; Figure 2 It is a partial cross-sectional view of the metal curtain wall panel and the metal curtain wall panel reinforcement structure, and the cross-section is in the normal direction of the metal curtain wall panel.

[0033] like Figures 1 to 4 As shown, this embodiment provides a metal curtain wall panel reinforcement structure 100, comprising a main reinforcement rib 10, a side reinforcement rib 20, and a plurality of L-shaped reinforcement angle pieces 30. The main reinforcement rib 10 is vertically arranged on the side of the metal curtain wall panel 1 facing the building, and has a contoured edge 11 that conforms to the shape of the metal curtain wall panel 1. The side reinforcement rib 20 is a strip-shaped plate arranged along the contoured edge 11 on one side of the main reinforcement rib 10 and is adhesively bonded to the metal curtain wall panel 1. A plurality of reinforcement angle pieces 30 are evenly arranged along the contoured edge 11 on the other side of the main reinforcement rib 10 and connected to the metal curtain wall panel 1 via nailing 31. The reinforcement angle pieces 30, the main reinforcement rib 10, and the side reinforcement rib 20 are fastened together by a plurality of bolts 32.

[0034] Specifically, the contoured edge 11 extends along the edge of the cross section of the metal curtain wall panel 1, and the height of the main reinforcing ribs 10 and the side reinforcing ribs 20 is substantially the same as that of the metal curtain wall panel 1, which can better and more fully support the metal curtain wall panel 1. The main reinforcing ribs 10 and the side reinforcing ribs 20 are obtained by laser cutting from raw metal sheets according to the shape and size of the metal curtain wall panel 1, without the need for a stretch-bending process, which greatly reduces the difficulty and cost of processing, and can achieve a high degree of fitting accuracy and is easy to install. The metal curtain wall panel reinforcement structure 100 of this embodiment is particularly suitable for curved metal curtain wall panels 1, and can fully fit the curvature of the curved surface, thereby improving the stability of the curtain wall. In addition, it can also be applied to traditional flat panels or other special-shaped panels. It is only necessary to determine the contoured edge 11 that matches the panel shape and cut the corresponding shapes of the main reinforcing ribs 10 and the side reinforcing ribs 20. It has a wide range of applications and few limitations.

[0035] Furthermore, the side reinforcing ribs 20 are connected to the metal curtain wall panel 1 via a silicone structural adhesive 21. This adhesive has excellent adhesion and aging stability. After curing into silicone rubber upon exposure to moisture in the air, it exhibits excellent toughness, effectively extending the service life of the metal curtain wall panel reinforcement structure 100. The silicone structural adhesive 21 is at least 6 mm thick and its width matches the thickness of the side reinforcing ribs 20, ensuring sufficient connection strength.

[0036] Preferably, the thickness of the main reinforcing rib 10 is 3 mm to 6 mm, and the thickness of the side reinforcing rib 20 is 6 mm to 10 mm.

[0037] Furthermore, the reinforcing corner piece 30 includes a first piece 33 connected to the metal curtain wall panel 1 and a second piece 34 connected to the main reinforcing rib 10. The first and second pieces 33, 34 are perpendicular to each other and have uniform thickness. Both the first and second pieces 33, 34 are 30 mm high and 3 mm thick, and their width in the direction tangent to the contoured edge 11 is 30 mm to 50 mm.

[0038] Furthermore, a threaded hole for installing a bolt 32 is provided in the middle of the second sheet 34, and threaded holes equal in number to the number of the reinforcement angle pieces 30 are also provided at corresponding positions on the main reinforcement ribs 10 and the side reinforcement ribs 20. The second sheet 34 of each reinforcement angle piece 30 is connected to the main reinforcement ribs 10 and the side reinforcement ribs 20 by a bolt 32. Preferably, the diameter of the bolt 32 is 5 mm. The middle of the first sheet 33 of each reinforcement angle piece 30 is connected to the metal curtain wall panel 1 by a nail 31, and preferably, the diameter of the nail 31 is 5 mm. A rubber pad 35 is also provided between the middle of the first sheet 33 and the metal curtain wall panel 1, which can absorb impact and vibration, reduce friction and wear, disperse pressure, and extend the service life of the curtain wall.

[0039] Furthermore, the spacing between adjacent reinforcement corner pieces 30 is no more than 250 mm, ensuring a high connection strength.

[0040] In actual applications, the number of metal curtain wall panel reinforcement structures 100 correspondingly arranged on the metal curtain wall panel 1 and the position and thickness of the main reinforcement ribs 10 in each metal curtain wall panel reinforcement structure 100 can be determined by calculation and analysis based on the actual engineering stress conditions. The thickness of the side reinforcement ribs 20 can be determined by calculation based on the arrangement spacing of the main reinforcement ribs 10 on the metal curtain wall panel 1 and the performance of the silicone structural adhesive 21. In each metal curtain wall panel reinforcement structure 100, the arrangement spacing of each anchor 31 shall not exceed 250mm, the arrangement spacing of each reinforcement angle piece 30 shall be determined based on the arrangement spacing of the anchor 31, and the arrangement spacing of the bolts 32 and threaded holes shall be determined based on the arrangement spacing of the reinforcement angle pieces 30.

[0041] During installation, first place the pre-cut side reinforcement ribs 20 with threaded holes vertically at the corresponding position on the surface of the metal curtain wall panel 1, use a glue gun to evenly apply silicone structural adhesive 21 to the joints between the two, ensure that the glue fills the gaps, and use a scraper to smooth the glue surface; after the silicone structural adhesive 21 is cured, place the pre-cut main reinforcement ribs 10 with threaded holes against the side of the side reinforcement ribs 20, and make the contoured edges 11 of the main reinforcement ribs 10 fit the surface of the metal curtain wall panel 1; then, use bolts 32 to connect the multiple reinforcement angle pieces 30 with threaded holes to the main reinforcement ribs 10 and the side reinforcement ribs 20 one by one, and tighten the bolts with nuts; finally, use nails 31 to fix all the reinforcement angle pieces 30 to the metal curtain wall panel 1 one by one, and the reinforcement angle pieces 30 and the side reinforcement ribs 20 form connection supports for the main reinforcement ribs 10 and the metal curtain wall panel 1 from both sides of the main reinforcement ribs 10.

[0042] In summary, the metal curtain wall panel reinforcement structure 100 of the present invention effectively solves the problem of difficulty in arranging reinforcement ribs of curved metal curtain wall panels in the prior art, avoids the profile bending process, and greatly reduces processing costs and construction difficulty.

[0043] The above-mentioned embodiments are preferred examples of the present invention and are not intended to limit the scope of protection of the present invention.
