Description

Technical Field

[0001] The present invention specifically relates to an assembled light steel keel composite board wall, belonging to the technical field of prefabricated walls. Background Art

[0002] Prefabricated buildings are buildings assembled on site from prefabricated components. According to the form of prefabricated components and the construction method, they are divided into block buildings, plate buildings, box buildings, frame plate buildings and rising plate and rising floor buildings. Among them, prefabricated light wall panels are an important part of prefabricated buildings. There are many different prefabricated light wall panels on the market, but most of the prefabricated light wall panels in the existing industry have too heavy product density. Generally, solid concrete is poured inside the mezzanine, which is not only difficult to effectively connect with the main structure of the building, but also easily causes an increase in the load on the main body of the building. Common problems such as leakage and cracks are prone to occur in the later stage. For this reason, China Patent Authorization Announcement No.: CN218406033U discloses a steel-concrete structure prefabricated light panel, which combines a steel frame with foam concrete to make the wall panel have the advantages of light weight, high strength and good integrity, and can become one with the building for the same lifespan, but the wall panel is difficult to construct and position; after installation, the earthquake resistance and deformation resistance are average.
