Wooden Cube whole house steel skeleton is composed of cold-formed light steel. Under the same section, the thin-walled section has a large radius of rotation and moment of inertia. Due to the influence of cold hardening during the forming process, the steel yield point is significantly improved, which is the so-called cold bending effect, which is beneficial to the mechanical performance of the component, thereby enhancing the strength of the component; the multi-directional bending of the section increases the inertia of the section and enhances the strength of the component. Light steel can save costs for transportation and installation because of its small weight. The installation of steel components in the whole house adopts the installation method of screws and bolts, which eliminates the problems of non-standard electric welding and easy rust of the weld joint. The structural design adopts independent numbering to reduce the possibility of construction errors.
