Description

Technical Field

[0001] This utility model belongs to the field of wall structure technology, and specifically relates to ultra-low energy consumption light steel composite wall 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 utility model is to provide an ultra-low energy consumption light steel composite wall structure to solve the technical problems of poor sound insulation and fire resistance of existing wall structures.

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

[0005] The ultra-low energy consumption light steel composite wall structure comprises, from indoors to outdoors, a sauna board layer, a graphite polystyrene insulation board layer one, a keel cavity layer, an OSB board layer one, an 89 light steel keel layer, an OSB board layer two, a polymer breathable paper layer, a graphite polystyrene insulation board layer two, an aerogel fireproof insulation board layer two, and a finishing layer. The polymer breathable paper layer is adhered to the OSB board layer two. The aerogel fireproof insulation board layer two, the graphite polystyrene insulation board layer two, the OSB board layer two, the OSB board layer one, the 89 light steel keel layer, the keel cavity layer, and the graphite polystyrene insulation board layer one are mutually fixed. The sauna board layer and the finishing layer are fixed by interlocking with the ground and the roof.

[0006] More preferably, the keel cavity layer is made of 45×120 anticorrosive wood, and the keel cavity is filled with aerogel fireproof and heat-insulating board.

[0007] In a further preferred embodiment, an aerogel fireproof insulation board layer is also provided between the graphite polystyrene insulation board layer and the keel cavity layer.

[0008] More preferably, the 89 light steel keel layer has a 280mm thick polyurethane sprayed on one side of the interior.

[0009] 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.

[0010] More preferably, the decorative layer is made of wood grain metal carved panel, which is a polyurethane sandwich panel with a thickness of 20mm.

[0011] More preferably, the thickness of both OSB layer one and OSB layer two is 9mm.

[0012] More preferably, the polymer breathable paper layer has a thickness of 0.5 mm, the aerogel fireproof insulation board layer two has a thickness of 50 mm, and both the graphite polystyrene insulation board layer two and the graphite polystyrene insulation board layer two have a thickness of 70 mm. The polymer breathable paper, as a functional material, 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 maintaining the dryness and stability of the wall. Although the polymer breathable paper itself does not possess significant thermal insulation performance, it can improve the overall durability of the wall and the comfort of living.

[0013] Further preferably, the thermal conductivity of the aerogel fireproof insulation board layer is 0.025 W / (m·K). Its fire resistance is Class A. The aerogel fireproof insulation board combines the ultra-low thermal conductivity of aerogel with the fire-resistant properties of inorganic materials, making it a leader among high-performance insulation materials. Its Class A fire resistance ensures the safety of the building in the event of a fire, while its excellent insulation performance helps maintain stable indoor temperatures.

[0014] Further preferably, the thermal conductivity of the first and second graphite polystyrene insulation board layers is 0.03 W / (m·K). The graphite polystyrene board incorporates graphite powder compared to traditional polystyrene boards, thereby improving its fire resistance and thermal insulation performance. The addition of graphite further reduces the thermal conductivity of the board and enhances its flame-retardant properties. Graphite polystyrene boards are lightweight, easy to cut, and convenient to install, making them an ideal choice for wall insulation.

[0015] This utility model adopts a multi-layer insulation design, with each insulation layer using different materials or structures, to fully utilize the advantages of various materials and improve insulation performance, thereby meeting the insulation requirements of different wall thicknesses and different energy consumption.
