Description

Technical Field

[0001] This utility model belongs to the field of roof structure technology, and specifically relates to ultra-low energy consumption light steel composite roof structure. Background Technology

[0002] Light steel structure housing is a relatively new housing system in my country. However, its promotion and application are still hampered by problems such as high cost, insufficient public awareness, and poor thermal insulation, sound insulation, and fire resistance of the housing. These issues have restricted the promotion and development of light steel structure housing in China. Utility Model Content

[0003] The purpose of this invention is to provide an ultra-low energy consumption light steel composite roof structure to solve the technical problems of poor sound insulation and fire resistance of existing roof structures.

[0004] This utility model is achieved using the following technical solution:

[0005] The ultra-low energy consumption light steel composite roof structure comprises, from indoors to outdoors, a suspended roof layer, OSB board layer one, aerogel felt layer one, 89 light steel keel layer, aerogel felt layer two, OSB board layer two, polymer breathable paper layer, waterproof membrane layer, and asphalt shingle layer. The asphalt shingle layer is fixed to the roof frame. The waterproof membrane layer is adhered to the polymer breathable paper. The polymer breathable paper is laid flat on OSB board layer two. Aerogel felt layer two and aerogel felt layer one are laid flat on the 89 light steel keel layer. OSB board layer one and OSB board layer two are fixed to the 89 light steel keel layer. The roof frame is fixedly connected to the 89 light steel keel layer. The suspended roof layer is fixedly connected to the 89 light steel keel layer.

[0006] More preferably, the thickness of both OSB layer one and OSB layer two is 9mm.

[0007] More preferably, the inner cavity on one side of the 89 light steel keel layer is sprayed with 280mm thick polyurethane.

[0008] Preferably, both the first and second aerogel felt layers have a thermal conductivity of 0.022 W / (m·K). Aerogel felt, with its extremely low thermal conductivity, represents a high-performance thermal insulation material. Its unique internal nanostructure effectively prevents heat transfer, resulting in excellent performance in maintaining stable indoor temperatures. Furthermore, aerogel felt also possesses good sound insulation and fire resistance properties, further enhancing building safety.

[0009] More preferably, the polymer breathable paper layer has a thickness of 0.5 mm. As a functional material, the polymer breathable paper is mainly used for moisture-proofing and breathability of walls. Its microporous structure allows moisture inside the wall to escape while preventing external moisture from intruding, effectively keeping the wall dry and stable. Although the polymer breathable paper itself does not have significant thermal insulation properties, it can improve the overall durability of the wall and the comfort of living.

[0010] Preferably, the polyurethane has a thermal conductivity of 0.02 W / (m·K). As an organic insulation material, polyurethane possesses excellent thermal insulation and waterproofing properties. Its on-site foaming process allows the polyurethane to adhere tightly to the wall, forming a continuous insulation layer and effectively reducing heat loss. Simultaneously, polyurethane also exhibits high mechanical strength and weather resistance, making it suitable for wall insulation in various complex environments.

[0011] More preferably, the ceiling layer is a sauna board.

[0012] More preferably, the thickness of both the first aerogel felt layer and the second aerogel felt layer is 10 mm.

[0013] The thermal insulation materials mainly used in this utility model all embody the design concepts of high performance, energy saving and environmental protection. The application of these materials and products will effectively improve the thermal insulation performance and living comfort of buildings, and contribute to the construction of a green and sustainable building environment.
