With technological advancements, their applications have expanded to large public buildings such as airports and stadiums. Currently, single-panel structures still face challenges such as thermal bridging and noise insulation, requiring optimization through composite construction, specifically:

[0003] 1) The single-panel structure is not good at indoor insulation, which means that in high or low temperature climates, it is necessary to continuously use cooling or heating equipment to regulate the indoor temperature, resulting in high energy consumption of indoor equipment and unsatisfactory energy-saving effect.

[0004] 2) Single-panel structure is not effective in isolating indoor noise. When a lot of noise is carried out indoors, it can be transmitted to the outside through the single-panel structure, causing a certain degree of noise impact on the surrounding area. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a metal roofing system structure with both heat insulation and sound absorption functions to solve the problems of poor heat insulation and poor sound insulation of the existing conventional metal roofing system, and to meet the needs of various use scenarios to the greatest extent.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a metal roofing system structure with both heat insulation and sound absorption functions, including several main steel frames fixed in parallel based on the metal roof, and several secondary steel frames vertically fixed at the outer end of the main steel frames away from the metal roof.

[0010] Furthermore, the main steel frame is embedded in the metal roof and fixed to the inner side of the metal roof with upper angle steel pieces.

[0011] Furthermore, one end of the upper angle steel member is connected to the side of the main steel frame, and the other end is perpendicular to the metal roof and fixedly connected to the metal roof; one end of the lower angle steel member is perpendicularly fixed to the other end of the upper angle steel member, and the other end supports the sound insulation layer.

[0012] Furthermore, the sound insulation layer comprises a plurality of sound insulation modules distributed along the height direction of the main steel frame.

[0013] Furthermore, the side of the secondary steel frame away from the metal roof is flush with the side of the main steel frame away from the metal roof.

[0014] Furthermore, the insulation layer includes an outer panel, a waterproof panel, and insulation cotton located between the outer panel and the waterproof panel, wherein the waterproof panel is fixed to the outside of the main steel frame and the secondary steel frame.

[0015] Furthermore, the outer panel is a pressure-resistant aluminum plate, and the waterproof panel body is a galvanized waterproof steel plate.

[0016] Furthermore, sealant is filled between adjacent insulation modules.

Detailed Implementation

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Figure 1 The schematic diagram shows a side sectional view of a metal roofing system that combines thermal insulation and sound absorption. Figure 2 The diagram schematically shows a front cross-sectional view of a metal roofing system that simultaneously provides thermal insulation and sound absorption. A metal roofing system with simultaneous thermal insulation and sound absorption functions is shown below. Figure 1 and Figure 2 As shown, the structure includes several main steel frames 1 fixed parallel to the metal roof, and several secondary steel frames 2 vertically fixed to the outer ends of the main steel frames 1 away from the metal roof. The sides of the secondary steel frames 2 away from the metal roof are flush with the sides of the main steel frames 1 away from the metal roof. A sound insulation layer is fixedly installed on the inner side of the metal roof based on the main steel frames 1, and a thermal insulation layer is fixedly installed on the outer sides of the main steel frames 1 and secondary steel frames 2. The sound insulation layer completes the sound absorption process inside the metal roof, and the thermal insulation layer outside the metal roof completes the thermal insulation of the metal roof. While satisfying the external thermal insulation function, the interior also has a sound absorption function, achieving a good functional effect and avoiding the effect of conventional metal roofs that are neither thermally insulated nor quiet.

[0025] The thickness of the sound insulation layer is no greater than the height of the main steel frame 1, and the thickness of the sound insulation layer inside the metal roof is the same as the height of the main steel frame 1 inside the metal roof. This ensures that the side of the sound insulation layer away from the metal roof is flush with the side of the main steel frame 1, guaranteeing the flatness and aesthetics of the interior of the metal roof. The aforementioned sound insulation layer includes sound insulation cotton 5 and perforated aluminum plate 4. The sound insulation cotton 5 is fixed to the inside of the metal roof with perforated aluminum plate 4, and the aforementioned metal roof is a powder-coated steel plate 6.

[0026] like Figure 1 As shown, the aforementioned main steel frame 1 is embedded in the metal roof, and the upper angle steel member 3 is used to fix the side of the main steel frame 1 to the inside of the metal roof, thereby fixing the main steel frame 1 and the metal roof as a whole. In the specific fixing process, one end of the upper angle steel member 3 is connected to the side of the main steel frame 1, and the other end is perpendicular to the metal roof and fixedly connected to the inside of the metal roof. The aforementioned sound insulation layer is fixedly installed on the inside of the metal roof by the lower angle steel member 11.

[0027] like Figure 2As shown, the first implementation method of fixing is as follows: one end of a lower angle steel member 11 is fixed to the inner side of the metal roof in a direction parallel to the main steel frame 1, and another lower angle steel member 11 is fixed to the side of the perforated aluminum plate 4 facing the metal roof in a direction parallel to the main steel frame 1. The other ends of the two lower angle steel members 11 are arranged opposite each other to support the sound insulation cotton 5 located between the metal roof and the perforated aluminum plate 4. The aforementioned sound insulation cotton 5 can be multiple pieces, and multiple sets of lower angle steel members 11 as described above are used to support multiple pieces of sound insulation cotton 5, thereby forming multiple sound insulation modules for combination into a sound insulation layer located inside the metal roof.

[0028] The second implementation method for fixing is as follows: one end of a lower angle steel member 11 is fixed to the inner side of the metal roof in a direction parallel to the main steel frame 1. This fixing is achieved by integrating the fixed end of the lower angle steel member 11 with the fixed end of the upper angle steel member 3 on the metal roof. Another lower angle steel member 11 is fixed to the side of the perforated aluminum plate 4 facing the metal roof in a direction parallel to the main steel frame 1. The other ends of the two lower angle steel members 11 are positioned opposite each other to support the sound insulation cotton 5 located between the metal roof and the perforated aluminum plate 4. The aforementioned sound insulation cotton 5 can consist of multiple pieces, which, together with multiple sets of lower angle steel members 11 as described above, support the multiple pieces of sound insulation cotton 5, thereby forming multiple sound insulation modules for assembly into a sound insulation layer located inside the metal roof.

[0029] like Figure 1 As shown, since the secondary steel frame 2 is flush with the side of the main steel frame 1 away from the metal roof, the insulation layer can be laid on the outside of the aforementioned secondary steel frame 2 and main steel frame 1. The insulation layer includes an outer panel 9, a waterproof board 7, and insulation cotton 8 located between the outer panel 9 and the waterproof board 7. The waterproof board 7 is fixed to the outside of the main steel frame 1 and the secondary steel frame 2 with screws. The outer panel 9 is a pressure-resistant aluminum plate, and the waterproof board 7 is a galvanized waterproof steel plate, used to prevent water seepage from the outer insulation layer. The insulation layer can be composed of several insulation modules, with sealant 10 filling the gaps between adjacent insulation modules to ensure that the insulation layer is a whole.

[0030] In actual installation, first connect the main steel frame 1 and the main support structure of the metal roofing system, then connect the secondary steel frame 2 to the main steel frame 1 to form the main load-bearing structure. Next, arrange the required upper angle steel pieces 3 at the required horizontal height, flatten them against the main steel frame 1, and secure them firmly. Then, fix the perforated aluminum plate 4 to the main steel frame 1 and the lower angle steel piece 11 with screws, ensuring flatness. Place the required sound insulation cotton 5 on top of the perforated aluminum plate 4, cover it with a powder-coated steel plate 6, and tighten it with screws to the upper angle steel piece 3. Seal the overlaps with adhesive to complete the entire sound insulation layer. Afterwards, place a galvanized waterproof steel plate on the main steel frame 1 and the secondary steel frame 2 and tighten it with screws. Seal the overlaps with adhesive, then place the required thermal insulation cotton 8 on top, cover it with a pressure-resistant aluminum plate, and tighten it with screws to the main steel frame 1 and the secondary steel frame 2. Fill and seal the joints of the aluminum plates with sealant 10. At this point, the entire structural system is installed.

[0031] The resulting structural system offers superior insulation and soundproofing compared to traditional, simple metal roofing systems. It is more practical and applicable to a wider range of scenarios, particularly meeting the requirements of applications with specific acoustic needs. The aforementioned metal roofing system, which combines insulation and sound absorption, is simple to construct, uses readily available materials, is easy to install, and has a short construction period. It can be prefabricated and installed only when conditions are met. It requires only the combination of various conventional materials to meet the installation and usage requirements of both general and special applications, achieving greater energy efficiency, quieter operation, and greater convenience. Furthermore, when different densities or colors of surface panels are needed, only the surface material needs to be replaced to meet different effects and functional requirements.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
