Prefabricated decoration, also known as industrial decoration. According to the “Technical Standards for Prefabricated Concrete Buildings” and “Technical Standards for Prefabricated Steel Structure Buildings” issued by the Ministry of Housing and Urban Rural Development in 2017, this technology refers to the decoration method of using dry construction methods to combine and install interior components produced by factories on site. It mainly has three characteristics:.

1. Dry assembly method: Avoid wet operations such as mortar leveling and bonding in traditional decoration, and instead use anchor bolts, supports, structural adhesives, and other methods to achieve support and connection structures..

2. Separation of pipelines and structures: Equipment and pipelines are not pre embedded in the building structure, but instead filled in the gaps between the six faces of the prefabricated space and the supporting structure..

3. Component Integration Customization: Integrating multiple dispersed components into an organism through specific manufacturing supply. Although the process is industrial production, it still needs to meet personalized customization to avoid on-site secondary processing..

Compared to traditional decoration, the biggest advantage of prefabricated decoration is that it can improve the dirty and disorderly environment of the construction site, effectively reduce environmental pollution such as construction waste, dust, and noise, improve the convenience of disassembling and assembling parts, shorten the construction period, and reduce maintenance costs..

At present, the prefabricated interior decoration technology for residential buildings in China has developed into fourteen major component systems, namely: ground system, partition system, wall panel system, door and window curtain wall system, suspended ceiling system, water supply and drainage system, hardware accessory system, waterproof and insulation coating system, pipeline system, whole kitchen system, whole bathroom system, HVAC mechanical and electrical system, intelligent smart system, and whole house home system..

However, compared with Japanese residential interior technology, there is still a lot of room for improvement in China’s prefabricated interior technology. Next, let’s take a look at Japan’s prefabricated interior technology for residential buildings..

The interior decoration technology of residential buildings in Japan was gradually formed through multiple stages of development under the promotion of government policies, among which the most critical historical events include:.

In 1970, Japan conducted research on the Kodan Experimental Housing Project (KEP) system, which achieved the separation of building structures and interior components to develop an open system that meets the personalized needs of users while using universal components..

In 1974, Japan conducted research and development on the KEP residential system with the aim of achieving component systematization. The system consists of external wall enclosure system, internal system, sanitation system, ventilation and air conditioning system..

In 1980, Japan began research on the Century Housing System (CHS), bringing residential properties closer to a state of “constant property” that can be passed down from generation to generation, allowing several generations of family members to live and work in peace for 100 years..

It can be seen that Japan is not solely relying on the main structure of residential buildings to improve the quality of housing, but is focusing on improving the component system, achieving the universality of interior component production, and thereby enhancing the user’s living experience..

Looking back at the development process of residential decoration technology in Japan, it has three main characteristics:.

Japan places great emphasis on the cultivation of integrated interior designers. Architects should delve deeper downstream and elevate to the forefront, including indoor living conditions, equipment structures, and products.
