Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated reinforced concrete structures, in particular to a prefabricated reinforced concrete composite wall with a cavity structure. Background Art

[0002] With the development of society and the acceleration of urbanization, prefabricated buildings are being gradually promoted. Prefabricated buildings can gradually break the limitations of traditional buildings and provide effective guarantees for the quality, safety and stability of construction projects while reducing labor. Among them, reinforced concrete composite walls are one of the prefabricated building structures.

[0003] Existing prefabricated reinforced concrete composite walls are usually connected to load-bearing columns or ordinary columns during installation, and the walls are not directly connected to each other, which requires pre-implantation of steel bars on the building before installation. After the prefabricated reinforced concrete composite walls are installed, the steel bars on the side of the wall are tied or welded to the reserved steel bars on the building, and then the formwork is supported and grouting is performed to form columns to complete the connection of the two walls, or a steel connection structure is directly used to connect the two walls. The pillar connection takes a long time and needs to wait until the concrete on the column is solidified, and the steel connection structure uses a large amount of steel, resulting in high costs.
