Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated wall. Background Art

[0002] Prefabricated wall refers to prefabricated wall panels or prefabricated plate-shaped components, which are reinforced concrete plate-shaped components processed in prefabrication plants or construction sites for building assembly. Using prefabricated concrete wall panels to build assembled large buildings can improve the degree of factory-based and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction cycle.

[0003] At present, prefabricated assembled concrete structures are mainly prefabricated shear wall structures, and most prefabricated concrete shear wall structures use sleeve grouting connection as the main force-bearing connection. In the vertical direction of the prefabricated wall, the reserved dowels at the top are connected to the reserved sleeves at the bottom in sequence, and in the horizontal direction, the steel bars extending from the sides of the adjacent prefabricated walls are tied to form hidden columns, and then the overall structure is formed by cast-in-place concrete. When pouring concrete, if a window is required on the prefabricated wall, the window must be reserved through a sealing structure such as a frame. After the poured concrete is cooled and solidified, a through hole for subsequent installation of the window can be formed. The opening of the window in the prefabricated wall can easily cause the instability of the prefabricated wall structure. In the process of demoulding or transporting the prefabricated wall, it is easy to cause the prefabricated wall structure to bend or break, so it is inconvenient to demould or transport the prefabricated wall with a window or other structural hole.
