Technical Field

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

[0002] There are two types of concrete slabs: cast-in-place and prefabricated. Cast-in-place concrete slabs have good integrity, but they have many processes, more wet operations, on-site pouring, and a longer construction period. In order to improve construction efficiency, prefabricated concrete slabs are widely used in roofs and floors of industrial and civil buildings.

[0003] A U-shaped prefabricated panel connection component is disclosed in the patent with the announcement number CN203684411U. When in use, the two connecting ends of the first U-shaped bolt need to be inserted into the through holes of the embedded parts of two adjacent prefabricated panels one by one, and then two nuts are threadedly connected to the two connecting ends of the first U-shaped bolt one by one, so as to achieve the connection of the two adjacent prefabricated panels. In this structure, after the first U-shaped bolt connects the two prefabricated panels, the side of the first U-shaped bolt away from the nut protrudes relative to the two prefabricated panels, occupying more indoor space.

[0004] Therefore, the technical problem to be solved by the present application is: how to reduce the space occupied by the connection between prefabricated panels. Utility Model Content
