Aluminum plate curtain wall

An aluminum plate curtain wall is characterized in that a composite panel (1) is fixedly arranged on a keel supporting piece (2) through a composite panel fixing assembly (3); the composite panel (1)is composed of an aluminum panel (1.1) and a heat preservation layer (1.2). The keel supporting piece (2) is composed of a main keel (2.1) and an auxiliary keel (2.2). Wherein the surface layer of theblocky heat preservation cotton combination body is provided with an aluminum foil with the thickness of 0.2-0.5 mm, and the total thickness of the blocky heat preservation cotton combination body isnot less than 50mm; the heat preservation layer (1.2) is a heat preservation layer; the aluminum panel (1.1) is a single-layer aluminum plate with the surface provided with a spraying layer with thethickness ranging from 0.05 mm to 0.2 mm and the total thickness ranging from 3 mm to 3.5 mm. The primary and secondary keel connecting assemblies (5) are composed of connecting plates (5.1) and connecting structures. The device
