▎ 摘　　要

NOVELTY - The structure has a light steel keel whose inner side and outer side are respectively provided with a first broken bridge heat insulating strip (10) and a second broken bridge thermal insulation strip (7). An outer side of the second broken heat insulation strip is equipped with a fire-proof OSB3 structural plate (6). A second graphene layer (5) is provided on an outer surface of the fireproof SOCB3 structure plate. A waterproof ventilating film (4) is attached to an outer side surface of second graphene. A second fireproof anti-corrosion wood keel (2) is arranged on the outside of the waterproof ventilation film. A metal heat insulation decorative integrated board (1) is installed on the outer surface. USE - Low energy consumption light steel composite wall structure for new building construction and old building energy-saving reconstruction. ADVANTAGE - The insulating layer has the function of heat preservation and heat insulation outside the building enclosure structure, reducing the external rain and snow, UV harmful corrosion substance and so on to improve durability of the main body structure. The structure internal stress caused by internal and external temperature difference of the building, reducing heat loss, at the same time, preventing the heat bridge portion from generating dewing. The wall is converted into a heat storage body by a heat transfer body, the temperature is stable to a certain degree, and the indoor heat comfort level. The composite wall has wide application range, it is not only suitable for new building construction, but also suitable for old building energy-saving reconstruction. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a low energy consumption light steel composite wall structure. 1Metal heat preservation and decoration integrated board 2Second fireproof anti-corrosion wood keel 3First layer cavity 4Waterproof ventilating film 5Second graphene 6Fireproof osb3 structural plate 7Second broken bridge heat insulation strip 8Light steel keel 9Second layer cavity 10First broken bridge heat insulation strip 11Gypsum board 12First fireproof anti-corrosion wood keel 13First graphene 14Air-tight layer 15Inner wall integrated wallboard decorative layer 16Air inlet
