Fabricated external wall system and manufacturing and installation method thereof

Abstract

The invention relates to a fabricated external wall system. The fabricated external wall system of a steel structure comprises an external decorative surface layer, a vacuum insulating plate layer, abase layer plate, a keel, a filling layer and an inner wall plate in sequence from outside to inside, the external decorative surface layer is fixed on the base layer plate, and the vacuum insulatingplate layer is arranged between the external decorative surface layer and the base layer plate. The base layer plate and the inner wall plate are separately fixed on the two sides of the keel. The filling layer is arranged in a cavity formed by surrounding of the base layer plate and the inner wall plate and separated by the keel, and the filling layer is a non-pouring filling material. Accordingto the fabricated external wall system of a steel structure, the base layer plate, the vacuum insulating plate or a STP heat preservation and decoration integrated plate can be effectively fixed through a set of elements; and mechanical connection is carried out on each layer, no hidden danger of shedding exists, the safety is improved, and the fabricated external wall system can be easily replaced when damaged.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a steel structure assembled exterior wall system and a manufacturing method and an installation method thereof. Background technique [0002] For thousands of years, the construction of houses has been using traditional construction methods, mainly by hand. The construction of houses by prefabricated components and mechanical hoisting has only a history of 20 to 30 years in my country. Practice has proved that the traditional way of building houses has a long construction period and consumes a lot of labor, which cannot meet the needs of construction. Developing prefabricated buildings and taking the road of factoryization and mechanization can speed up the construction progress and reduce the labor intensity of workers. In recent years, the construction volume of prefabricated buildings has developed greatly, and has gradually become a major architectural form. Prefabricate...
