Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated building walls, and specifically relates to a connecting piece for prefabricated building walls. Background Technique

[0002] The prefabricated wall adopts the principle of cast-in-place shear wall, uses galvanized light steel keel as the support framework, and high-strength magnesium oxide board as the demountable panel. After pouring environmentally friendly and flame-retardant lightweight slurry inside the magnesium oxide board, the wall is finally formed.

[0003] The existing prefabricated walls will produce building walls with different heights and different thicknesses according to the assembly requirements. Since the sizes of the building walls are different, the connecting pieces need to be adjusted according to the shape of the building walls. However, when the existing building wall connecting pieces are in use, their structures are single and cannot be adjusted according to the shape of the building walls, so the applicability of the connecting pieces is relatively low.

[0004] Therefore, a connecting piece for prefabricated building walls is proposed. Content of the Utility Model
