[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled wall structure that is easy to install. Background Art

[0002] Prefabricated buildings are assembled on site from prefabricated components, that is, prefabricated components are manufactured in batches and sets in prefabrication factories, and then transported to the construction site for assembly. Prefabricated buildings are fast to construct, have a short construction period, low investment cost, controllable quality, good environmental protection, and are widely promoted and applied. For example, the applicant's prior application document: a modular assembled independent house structure (application number 2024210442638), which includes a bottom plate, a middle plate and a top plate arranged in sequence from bottom to top, the middle plate is a multi-layer arrangement, and the sides around the bottom plate and the middle plate, the adjacent middle plates, and the middle plate and the top plate are all provided with external walls, forming a multi-layer floor unit; a number of internal partition walls are provided in each floor unit, and the adjacent two floor units are connected by prefabricated stairs. The utility model adopts modular production of various prefabricated components in the factory, and then transports various prefabricated components to the construction site, and uses assembly methods to complete the construction of the entire house. Compared with existing assembled buildings, the cast-in-place process can be omitted, which greatly shortens the construction period and saves construction costs and manpower investment. However, in this overall assembled building, each wall panel, bottom plate and top plate are assembled with factory prefabricated parts, with many connection points, and the processing errors of each prefabricated part are large, resulting in problems such as difficulty in assembly and low precision in the subsequent assembly process.
