The invention provides a wall structure of an integrated house, and belongs to the technical field of machines. The problems that an existing wall structure is poor in connecting strength and stability and low in building efficiency are solved. The wall structure of the integrated house comprises a first wall body and a second wall body, and supporting keels are arranged in wall corners formed bythe first wall body and the second wall body. Each supporting keel comprises two bent supporting plates, wherein the two supporting plates are symmetrically arranged and are attached and fixed to eachother, one side edge of each supporting plate is bent inwards to form a first connecting plate, the other side edge of the each supporting plate is bent inwards to form a second connecting plate, a first connecting piece is fixed to each first connecting plate and/or a second connecting piece is fixedly arranged on each second connecting piece, an opening is formed between the first connecting plate and the second connecting plate on the same supporting plate, the two wall corners of the second wall body and the first wall body penetrate through the two openings of each supporting keel and are located in the supporting keels, and the first connecting plates and the second connecting plates are located in the first wall body and the second wall body respectively. The wall structure is highin connecting strength and stability and high in construction efficiency.
