Description

Technical Field

[0001] The utility model belongs to the technical field of roof construction, and in particular relates to a metal roof system based on a corrugated asphalt waterproof sheet. Background Art

[0002] In the field of construction, as people's requirements for building quality continue to increase, the current roof structure is required to have both thermal insulation and waterproofing functions. Metal roofs have been widely used in the field of building roofs due to their light weight, high strength, good durability and beautiful appearance. Especially in large public buildings, industrial plants and other occasions, metal roofs have become the preferred material due to their excellent performance. The existing waterproof and thermal insulation metal roof usually adopts the following structure, including a reinforced concrete slab, a fine stone concrete protective layer, a cement mortar leveling layer, a waterproof layer, an insulation board and a metal roof panel arranged from bottom to top. Although the above-mentioned existing slope roof structure also has a waterproof layer and an insulation board, that is, it has the functions of thermal insulation and waterproofing, but because the waterproof layer is under the lower insulation board, once the insulation board absorbs too much water, the waterproof layer will be in a state of water accumulation for a long time, and the waterproof effect is difficult to guarantee; and the excessive water absorption rate of the insulation board increases the heat transfer coefficient, resulting in the entire slope roof structure. The thermal insulation and waterproofing effect is not ideal; in addition, the use of a fine stone concrete protective layer as the surface layer of the slope roof structure not only increases the carrier of the slope roof structure, but also has a high comprehensive cost and a long construction period.

[0003] Although metal roofs have many advantages, their practical applications have also exposed some problems that need to be solved urgently, mainly including the two major problems of noise and heat radiation.

[0004] Noise problem: Metal roofs tend to generate a lot of noise in windy and rainy weather, mainly due to the high reflectivity and resonance characteristics of the material. To alleviate this problem, the existing technology generally adopts the practice of laying an insulation layer under the metal roof panel. Although the insulation layer can absorb and reduce noise to a certain extent, since the metal roof structure needs to be supported by tile strips, the noise may still be transmitted to the external environment through the supporting structure and cannot be completely eliminated. In addition, the noise reduction effect of the insulation layer is limited, and the improvement of the indoor environment is not significant enough.

[0005] Heat radiation problem: Metal roofs heat up quickly under sunlight, generating a large amount of heat radiation, which causes the top floor to heat up and affects living comfort. Although existing technologies have attempted to slow down heat transfer by laying an insulation layer, the insulation effect of the insulation layer is limited, and significant heat radiation can still be felt indoors, especially in hot seasons. This not only increases building energy consumption, but also reduces living quality.

[0006] Therefore, the utility model designs a metal roof system which reduces cost, improves construction efficiency, has a simple structure and has the functions of waterproofing, heat preservation, ventilation and sound insulation. Utility Model Content

[0007] In view of the problems existing in the prior art, the utility model provides a metal roofing system based on corrugated asphalt waterproofing sheets which reduces costs, improves construction efficiency, has a simple structure, and has the functions of waterproofing, heat preservation, ventilation, and sound insulation.

[0008] The utility model is implemented as follows: a metal roofing system based on a corrugated asphalt waterproof sheet comprises a roof foundation, characterized in that: a waterproofing coil, a thermal insulation layer and a corrugated asphalt waterproof sheet are sequentially laid on the upper surface of the roof foundation, water-adjusting strips are spaced apart on the corrugated asphalt waterproof sheet, and leveling components are spaced apart on the upper surface of each of the water-adjusting strips, and the centers of the leveling components of adjacent water-adjusting strips are located on the same straight line; prefabricated holes are provided on the leveling components, fastening screws are installed in the prefabricated holes, and the fastening screws are sequentially passed through the leveling components, the water-adjusting strips, the corrugated asphalt waterproof sheet and the thermal insulation sheet to be fixedly connected to the roof foundation; tile hanging strips perpendicular to the water-adjusting strips are installed on the leveling components on the same straight line, the tile hanging strips are buckled in the leveling components, and the upper surface of the tile hanging strips is installed with a metal roof panel through a connecting assembly; at least the non-buckled overlap area of ​​the backlight surface of each metal roof panel on the sunny side is compounded with a heat-reflecting and sound-absorbing composite layer.

[0009] The leveling component includes a horizontal connecting portion with a planar bottom surface, hollow supporting portions are provided on both sides of the connecting portion, a vertical stop portion is provided on the outer side of the supporting portion, and a limiting protrusion extends from the upper end of the vertical stop portion toward the center direction of the horizontal connecting portion.

The height of the buckling portions is equal to the distance between the limiting protrusion of the leveling member and the supporting portion, and the buckling portions abut against the space between the limiting protrusion of the leveling member and the supporting portion.

[0011] Preferably, the heat-reflecting sound-absorbing composite layer includes a sound-absorbing core layer, which is used to reduce the noise generated by external force impacting the metal roof body; the two sides of the sound-absorbing core layer are composited with an external heat-reflecting film and an internal heat-reflecting film, the external heat-reflecting film is fixedly connected to the backlight surface of the metal roof body, and is used to reflect the heat radiation generated by sunlight toward the light-facing surface; the internal reflective film is used to reflect the heat radiation dissipated in the direction of the waterproof asphalt waterproof board.

[0012] Preferably, the thickness of the outer heat reflective film and / or the inner heat reflective film is 0.03-100 μm.

[0013] Preferably, the outer heat reflective film or the inner heat reflective film is a metal foil or a polyester film as a substrate, and a metal layer with high reflectivity is coated on the surface.

[0014] Preferably, the thickness of the sound-absorbing core layer is 0.1-100 mm.

[0016] The utility model has the advantages and technical effects: the metal roofing system based on the corrugated asphalt waterproof sheet of the present invention shows many significant advantages, especially in waterproofing, heat reflection and noise reduction.

[0017] In terms of waterproof performance, the system effectively prevents rainwater or other water sources from penetrating into the roof structure layer by laying a layer of high-quality waterproof membrane as the last waterproof barrier, ensuring the basic waterproof performance of the roof. At the same time, the use of corrugated asphalt waterproof sheet further enhances the waterproof effect. The waterproof sheet is made of plant fiber impregnated with asphalt under high temperature and high pressure. It is dense and thick, has excellent waterproof performance, and significantly reduces the risk of leakage.

[0018] By compounding a heat-reflecting sound-absorbing composite layer on the backlight surface of the metal roof, the utility model effectively solves the problem of high noise in traditional metal roofs. The sound-absorbing material built into the composite layer can absorb and reduce the noise generated by the metal roof in windy and rainy weather, significantly reducing the transmission of noise into the room, and providing a quieter and more comfortable environment for residents. The integrated composite design ensures that the sound-absorbing material fits tightly with the metal roof body without gaps, further improving the noise reduction effect.

[0019] The heat-reflective sound-absorbing composite layer not only has a sound-absorbing function, but also has excellent heat-reflective performance. It can reflect the heat generated by sunlight, reduce the transfer of heat into the room, and effectively reduce the indoor temperature. Compared with the traditional technology of independently setting a heat-reflective film under the metal roof tile, the integrated composite design of the utility model avoids the problem of heat accumulation between the metal roof tile and the heat-reflective film, improves the heat reflection efficiency, and makes the heat insulation effect more significant.

[0020] In summary, the metal roofing system based on the corrugated asphalt waterproof sheet of the present invention performs well in waterproofing, heat reflection and noise reduction, and can not only effectively prevent water source penetration and reduce the risk of leakage, but also significantly reduce the absorption of solar radiation heat and reduce indoor temperature, while providing excellent noise reduction effect, creating a more comfortable and quiet living environment for residents. These advantages make the present invention have broad application prospects and promotion value in the market. BRIEF DESCRIPTION OF THE DRAWINGS
