Description

Technical Field

[0001] The utility model belongs to the technical field of metal roofs of construction projects, and in particular relates to a metal roof structure with ventilation and noise reduction. Background Art

[0002] Traditional metal roof structures have significant defects in ventilation, noise reduction, insulation, and waterproofing. There is usually a lack of effective ventilation design, which leads to heat accumulation problems in hot weather. In addition, metal roof structures with strong surface reflectivity are difficult to effectively prevent the spread of external noise, which has a significant impact on buildings in noise-sensitive areas. The lack of comprehensive insulation design makes it easy to lose heat in cold seasons, increasing energy consumption. The single-layer waterproof layer is easily damaged, which may cause water seepage problems and damage the building structure. The lack of structural firmness and the inferior metal materials that may be used further reduce the performance of traditional metal roof structures. In summary, traditional metal roof structures have limitations in design and performance, and need to introduce advanced ventilation, noise reduction, insulation and waterproofing technologies to improve the overall building quality. Summary of the invention

[0003] In order to solve the above-mentioned problems, the utility model provides a metal roof structure with ventilation and noise reduction, which is suitable for improving the comfort and durability of the building and reducing the environmental noise.

[0004] In order to achieve the above purpose, the specific technical solution of this application is as follows:

[0005] A metal roof structure with ventilation and noise reduction comprises a parapet and purlins, wherein an NLT board is arranged above the purlin, a wooden grille is arranged on the NLT board, ventilation holes are arranged on the wooden grille, each space of the wooden grille is filled with a thermal insulation cotton sheet, an OSB board is laid above the wooden grille, a waterproof layer is laid above the OSB board, a ventilation and noise reduction wire mesh is laid on the waterproof layer, and a metal roof panel is laid above the ventilation and noise reduction wire mesh.

[0006] Based on the above technical features, preferably, the size of the thermal insulation cotton sheet is 1-2 cm larger than each side of the wooden grille space.

[0007] Based on the above technical features, further, the waterproof layer is provided with two layers, and the two waterproof layers are laid in parallel and staggered with 1 / 2 width.

[0008] Based on the above technical features, preferably, the ends of the ventilation and noise reduction wire mesh are fixed to the wooden grille.

[0009] Based on the above technical features, preferably, the metal roof panel is an aluminum-manganese-magnesium alloy roof panel.

[0010] Based on the above technical features, preferably, the metal roof panel is firmly connected to the ventilation and noise reduction mesh by screws.

[0011] Based on the above technical features, preferably, the screw spacing is 1 meter.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] By installing wooden grilles and ventilation and noise reduction mesh in the metal roof structure, the ventilation effect is effectively improved, the spread of noise is prevented, and the reflection of external noise by the metal roof structure is reduced. This has a significant noise reduction effect for places that are sensitive to environmental noise, such as residential and commercial areas. The ventilation holes on the wooden grilles and the ventilation and noise reduction mesh work together to allow air to circulate, prevent local heat accumulation, and improve the ventilation performance of the building;

[0014] The use of two parallel and staggered waterproof layers effectively improves the waterproof performance of the roof. When the single waterproof layer is damaged, the waterproof performance of the roof can still be maintained, thus enhancing the durability of the overall roof structure.

[0015] The wooden grille is filled with thermal insulation cotton sheets, which effectively increases the thermal insulation performance of the roof. The reasonable size of the thermal insulation cotton sheets fills the spaces in the wooden grille, helping to reduce heat conduction and improve the energy efficiency of the building.

It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] It should be noted that the words "up", "down", "left", "right", "front" and "rear" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] In the description of the present invention, "several" means two or more than two, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 As shown, an embodiment of a metal roof structure with ventilation and noise reduction includes a parapet 1 and a purlin 2. An NLT board 3 is arranged above the purlin 2. The NLT board and the purlin, and adjacent NLT boards are fixed by nailing.

[0023] The NLT board 3 is provided with a wooden grille 4, and the wooden grille 4 is provided with ventilation holes 401. Each space of the wooden grille 4 is filled with a heat-insulating cotton sheet 5. Preferably, the size of the heat-insulating cotton sheet is 1-2 cm larger than each side of the wooden grille space. The heat-insulating cotton sheet 5 is filled in the wooden grille 4, which effectively increases the thermal insulation performance of the roof. The reasonable size of the heat-insulating cotton sheet fills the wooden grille space, which helps to reduce heat conduction and improve the energy efficiency of the building.

In this embodiment, the waterproof layer includes a first waterproof layer 7 and a second waterproof layer 8, and the first waterproof layer 7 and the second waterproof layer 8 are staggered and laid with 1 / 2 width. The waterproof layer is constructed with self-adhesive waterproof coiled material and must be firmly pasted. Tear off the isolation film of the self-adhesive waterproof coiled material and remove it slowly and evenly along the coiled material to the other end to avoid wrinkles on the self-adhesive waterproof coiled material, ensure sufficient exhaust, and evenly press the self-adhesive waterproof coiled material with the isolation film removed to make it tightly adhere to the base layer. The overlap of the long and short sides is 100mm. The overlap seam should be evenly pressed on the top surface of the upper coiled material, with the edge being tightly bonded. If necessary, a hot air welding gun should be used to close the seam.

[0026] A ventilation and noise reduction wire mesh 9 is laid on the second waterproof layer 8, the ends of the ventilation and noise reduction wire mesh are fixed to the wooden grille, and the edges are closed.

[0027] A metal roof panel is laid on the ventilation and noise reduction wire mesh. Preferably, the metal roof panel is an aluminum-manganese-magnesium alloy profiled roof panel, which has the advantages of light weight, high strength, corrosion resistance, etc., and provides a long service life and weathering resistance.

[0028] Based on the above technical features, preferably, the metal roof panel is firmly connected to the ventilation and noise reduction wire mesh by screws, and the screw spacing is 1 meter.

[0029] In summary, the ventilation and noise reduction metal roof structure provided in the present application utilizes design elements such as thermal insulation cotton sheets, ventilation holes on wooden grilles, ventilation and noise reduction meshes, and waterproof layers to achieve a metal roof structure with superior comprehensive performance, which is suitable for improving the comfort and durability of buildings and reducing environmental noise requirements.
