Multi-layer aeration combined film body for performing heat preservation on building

Abstract

The invention discloses a multi-layer aeration combined film body for performing heat preservation on a building. The combined film body comprises at least four layers of flexible films, wherein an inter-film layer is formed between every two adjacent layers of flexible films; aeration pipes connected with the flexible films are arranged in the inter-film layers; aeration side frames are formed by aeration pipes positioned at the peripheries of the inter-film layers; aeration ribs are formed by aeration pipes positioned between the aeration side frames; a space in each inter-film layer is separated into a plurality of communicated core part chambers by the aeration ribs and the aeration side frames which are positioned in the same inter-film layer; the aeration pipes are respectively communicated with an air tap; and the air tap is fixed on the combined film body. The combined film body is energy-saving and environment-friendly, has obvious heat-preservation and thermal-insulation effects, and the heat preservation performance of the building can be improved; and the combined film body is simple in manufacturing process and low in cost, and can be conveniently manufactured on a large scale, the building cost can be reduced, the manufacturing difficulty is reduced, and the combined film body is low-carbon, environment-friendly and renewable and can be recycled.

Description

Technical field [0001] The invention relates to a composite membrane body, in particular to a multilayer inflatable composite membrane body used for building heat preservation. Background technique [0002] At present, in order to meet the requirements of energy saving, buildings in our country use a large number of thermal insulation materials as the thermal insulation layer of the outer protective structure, and most of the doors and windows use broken bridge aluminum frames and LOW-E insulating glass to meet the thermal insulation requirements. However, the heat transfer coefficient of walls can generally only reach about 0.5, and the heat transfer coefficient of windows can only reach about 2.0. With the promotion and development of building energy conservation and green buildings in my country, some walls require a heat transfer coefficient of 0.35, The heat transfer coefficient is required to be 0.8. Therefore, the thickness of the thermal insulation layer is greatly increa...

Problems solved by technology

Therefore, the thickness of the insulation layer is greatly increased, not only the building structure is extremely complicated and the cost is too high, but also many structures are unscientific, unreasonable, and do not prolong the life.
