Inner template assembly and gutter inlet template

The utility model discloses an inner formwork assembly and a gutter inlet formwork. The inner formwork assembly comprises at least two long-edge formworks. The short-edge templates and the long-edge templates are alternately arranged, and each short-edge template and each long-edge template enclose to form a closed structure; the at least two buckle assemblies are located in the closed structure, each buckle assembly is arranged on the corresponding short-edge formwork in a crossing mode, one end of each buckle assembly abuts against the corresponding long-edge formwork on one side, and the other end of each buckle assembly abuts against the corresponding long-edge formwork on the other side; and therefore, the short-edge templates are fixedly connected with the long-edge templates on the two sides. The connecting piece is arranged in the closed structure defined by the long-edge formwork and the short-edge formwork, the influence of small construction space of the gutter inlet can be overcome, the connecting
