Abstract:

The laying of electrical pipelines in urban collective residences generally involves passingthrough structural floor slabs and walls,which not only causes conflicts in the design stage, but alsobrings difficulties in later maintenance and renewal. By drawing on research results, such as the BuildingSI System and practical cases of model rooms, this paper ensures the layout requirements and designeffects of lighting fixtures in coordination with interior decoration. It realizes pipeline routing separatedfrom the structural main body by utilizing horizontal and vertical spaces, such as wall skirting lines,corner lines, and equipment integration belts in prefabricated decoration. Meanwhile, methods like opentrough wiring and decorative gussets can be adopted to meet the needs of visual installation andmaintenance. Thus, the complete separation between the wiring of indoor strong and weak electricalpipelines in residences and the structural system is achieved, ensuring the long⁃term durability of thebuilding structure, the flexibility and variability of interior decoration.
