Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, and in particular to an integrated structure combining an extruded hollow exterior wall cement board and a light steel wall. Background Art

[0002] Extruded hollow exterior wall cement board is made of silicate cement, fiber, such as pulp fiber, polypropylene fiber, etc., and siliceous materials as the main raw materials. It is formed by vacuum high-pressure extrusion, and then cured by low-temperature steam and high-temperature and high-pressure curing to form a hollow strip board. It has the characteristics of light weight, good durability, and good fire resistance. When used for exterior wall enclosures, the load on the structure is lower than that of traditional masonry walls.

[0003] At present, when the extruded hollow exterior wall cement board is combined with the light steel wall for installation, a keel is usually set on the surface of the light steel wall, and then the extruded hollow exterior wall cement board is drilled and fixed to the keel, which damages the surface of the extruded hollow exterior wall cement board and affects the aesthetics of the splicing installation of the extruded hollow exterior wall cement board. At the same time, by installing the extruded hollow exterior wall cement board and the keel alone, the stability is low and it is easy to fall off in the later stage. In addition, the gaps between the extruded hollow exterior wall cement boards are usually connected by sealants and foam strips, which has high requirements on the construction environment, short service life and low practicality.
