(57) Disclosed is a prefabricated wall (1) for a prefabricated building. The prefabricated wall comprises a concrete body (2) and a rigid framework (3) arranged inside the poured concrete body (2), wherein the rigid framework (3) comprises n longitudinally extending ver­tical rebars (4), with n being an integer greater than or equal to three; an upper end face and a lower end face of the prefabricated wall (1) are formed with m mechan­ical connection portions (5) at positions sharing the same axes as the vertical rebars (4), with m being an integer less than or equal to 2n; and the mechanical connection portions (5) are all formed at end portions of the vertical rebars (4). Further disclosed is an assembly structure for a prefabricated building. The assembly structure is formed by filling an assembly gap with an on-site poured layer (17) after rebars are firmly connected at an over­head region (18) between an upper-layer wall (10), a low­er-layer wall (11) and a floor slab by means of fastening components (12). Further disclosed is a construction method for a prefabricated building. The structure is re­liable in terms of connection, has a simple structure and is easy to construct.
