T-shaped prefabricated mixed coupled wall

A T-shaped prefabricated mixed coupled wall comprises a first wall unit and a second wall unit which are perpendicularly connected to form the T shape, wherein the first wall unit and the second wall unit are respectively a prefabricated part, and the first wall unit and the second wall unit are connected through a joint post-cast strip. According to the T-shaped prefabricated mixed coupled wall, a steel beam is used for replacing a concrete beam, a section steel column is used for replacing an edge-constraining reinforced concrete embedded column, and therefore the mixed coupled wall has better energy dissipation capacity and continuous collapse preventing capacity than a traditional coupled wall, prefabrication and filed installation are performed synchronously, the problems that wet construction quantity is large on a construction site, and much building waste is generated are solved, the using requirement of a building can be met conveniently, and the assembly working procedures are simplified conveniently; after short beams of joints are in butt welding, large rigidity is formed between the wall units, stability of the wall is facilitated in the constructing process, the working procedure that a prefabricated shear wall serves as a temporary support is omitted, and construction efficiency is guaranteed. The L-shaped prefabricated mixed coupled wall can be widely applied to construction of mixed coupled walls in constructional engineering.
