Is the assembled inner air vent really coming? In the past few years, in the context of the transformation and upgrading of traditional industries, the decoration industry has received short-term attention and bets from the capital market because of its large market size, but it has not brought much change to the industry. In addition, the enterprises themselves do not have the ability to deliver quality. A large number of enterprises have ignited a false fire with the help of capital, and finally they have all died in succession. The traditional production mode is gradually disconnected from the acceleration of industrial innovation, while the new productivity mode is mostly discussed as "assembly decoration". Integrated design, prefabricated production, assembly installation, and information management are the main features of assembly decoration. Essentially, industrial production thinking replaces on-site processing thinking, The structural space of the house is divided into modules, and the integrated parts are installed through industrial production, which greatly reduces the construction period, the uncontrollability of workers' technology, and the cost of labor and materials. The impact of prefabricated technology on the entire decoration industry will continue to intensify This is a battle of efficiency, experience and cost launched by new technologies, new concepts, new policies and new directions to the traditional decoration industry, and it may also be a reorganization after the original unstable brand pattern is completely broken up. In the context of Industry 4.0, the industrialization path of the large residential industry will take assembly as the main path, extending upward to architectural design and construction, downward to include home decoration and partial renovation, Foshan steel structure The word assembly, which seems strange, will be closely related to everyone's daily life in the future. Future potential of prefabricated interior decoration The construction industry brings 60 trillion output value to the world every year and provides 20 trillion growth for China's GDP. However, throughout the development of the industry, it is still in a stage of subcontracting, poor management and low efficiency. Home decoration industry has developed for nearly 30 years, and non-standard operation has always been one of the major pain points of the industry. Home decoration is a typical labor-intensive industry. In the traditional wet decoration, each decoration site is a small production workshop, and the product quality depends on the craftsmanship of construction personnel in each process of water, electricity, wood, tile, oil, etc. The fabricated technology of Foshan steel structure can be said to be a process or an idea of industrial construction. Each company has different understanding and implementation methods. Different companies will create their own fabricated products from different perspectives, customer positioning and structural analysis. The decoration method provided by assembly is the transformation from on-site service of craftsmen to factory production. The intervention of assembly will make the home decoration industry take shape Industrialized low-end decoration, refined and handmade high-end market Pattern. At present, prefabricated interior decoration has outstanding advantages in standardized and mass decoration projects, such as long-term rental apartments, retirement apartments, hotels, etc., which can maximize the advantages of prefabricated interior decoration, greatly shorten the construction period, and also enable the project to quickly enter into operation and reduce costs. Obstacles to the development of China's traditional construction industry 1. The labor supply side is insufficient, and the bonus of construction workers has faded
During the two sessions in 2019, the change in the number of labor force population deserves the attention of the whole industry: from the supply side, the working age population has continued to decrease, with a cumulative decrease of about 28 million people since 2012. From 2013 to 2018, the proportion of China's working population declined from 73.9% to 71.8%; Within ten years, the average wage of urban unit employment has increased by 2.57 times, and the compound annual growth rate has reached 10%

Data from: National Bureau of Statistics Moreover, Keynesian theory points out that wages have downward rigidity, the transfer of rural labor to cities has slowed down significantly, and the annual net increase of migrant workers has declined from 12.45 million in 2010 to 1.84 million in 2018. The change in the number of labor force population is also a reminder that the artificial bonus is fading. If the decoration industry continues to use the traditional construction methods, it is likely that there will be pressure on employment. 2. The pollution problem of traditional construction industry is serious, and it is imperative to complete the construction industrialization Data shows that the direct energy consumption of buildings in China has risen from 10% in the late 1970s to 30% in recent years. If building materials are added, it is expected to be about 40%, that is, About 1/3 of China's energy is consumed in the construction industry 。 In addition to the consumption of building materials, most buildings still use the traditional cement mortar construction method at present, which not only has a long construction period, but also consumes a lot of manpower and causes serious environmental pollution. The future development demands of the construction industry will mainly focus on the realization of industrialization 。 Whether at the national, market, industry or user level, there are higher requirements and standards for building industrialization. 3. Assembled continuous online, enabling building industrialization With fewer and fewer traditional craft practitioners and less and less non renewable material resources, it is urgent for the construction industry to change the decoration mode of the inherent way. Facing the huge market demand, industrialization has become a way to greatly improve the efficiency of decoration and reduce costs. One way to realize industrialization is to develop assembly technology. It is understood that prefabricated buildings can reduce the on-site construction time by at least 50%, and the erection site is basically free of dust and construction waste, minimizing the environmental problems caused by traditional building methods; In addition, due to the technical convenience brought by digitalization, the collaboration speed and efficiency in all aspects have been greatly improved. Policy Promotion of Assembled Development In recent years, Foshan steel structure prefabricated buildings have attracted great attention from all walks of life. Under the call of the highest decision-making level of the country to 'develop prefabricated buildings and promote the industrialization of new buildings', local governments have also responded to the call to actively plan policies related to prefabricated interior decoration. With the introduction of assembly type plans in various provinces and cities, many real estate and decoration enterprises attach great importance to the policy preference, and have devoted their efforts to promoting the development of "assembly type".

Industrial Characteristics and Solutions of Assembled Interior Decoration
1. Assembled decoration is mainly for interior decoration to build industrial residential buildings
Fabricated technology mainly includes concrete building system, steel structure building system, interior decoration system, exterior enclosure technology system, equipment and pipeline and other product technology systems.
Assembled building product system
In the home decoration industry, the assembly technology often mentioned mainly refers to the assembly interior decoration, which mainly changes and subverts the traditional inefficient decoration mode, and builds industrial residential buildings based on improving quality and efficiency.
The core of assembly type is standardized design, modular production, and assembly type construction (separation of SI pipelines is conducive to the later enclosure operation, creating large indoor space, and bringing plasticity). Some enterprises will also provide more quality oriented residential solutions.
2. Four industrial characteristics of prefabricated interior decoration, information management of furniture production data Assembled interior decoration refers to the combination and installation of decoration parts, equipment pipelines, etc. produced by the factory by dry construction, and the integrated design of assembly decoration and structural system, exterior wall system, interior wall system, equipment pipeline system is comprehensively considered. Essentially, it is the logic of industrial products, and industrial production thinking replaces on-site processing thinking. Main characteristics of assembly type interior decoration: Realize integrated design from the source, building pipeline separation, whole process component modular design, BIM 3D model forward design, multi discipline collaborative design, one click drawing and list. (2) Prefabricated production Factory integrated production of parts and components, large CNC precision production equipment batch production, small error, ensure the stability and reliability of product quality, improve the resource waste caused by traditional extensive production. Modular design and production of components, factory management of the construction site, full dry assembly decoration, purification of the construction environment in the project, realization of zero error in the installation process, and enhancement of the interoperability of components. (4) Information management Strictly control the production, warehousing and transportation of components according to the construction process of prefabricated decoration, and monitor the whole process of prefabricated components; Collaborative management, optimization of information and dynamic intelligent services can effectively solve the data sharing and exchange in the prefabricated industrial chain. 3. Main solution of assembly type interior decoration, multiple space modularization Assembled interior decoration is mainly composed of floor, wall, top surface, wiring system, integrated kitchen and bathroom and other space systems. Through modular design and industrial production, assembled interior decoration only needs integrated parts for installation, greatly shortening the construction period, reducing the uncontrollability of workers' technology, reducing labor costs, material costs, maintenance costs, and avoiding indoor decoration pollution. Of course, personalized needs at the end can be solved through decentralized channels, Assembly type brings about the industrialization of the whole industrial chain of decoration.
Development resistance of assembled interior decoration The current mainstream operation mode of Foshan steel structure prefabricated interior decoration is to form an upstream and downstream cooperation relationship with the decoration company in product supply. The prefabricated enterprise provides solutions, products and technical guidance, and the decoration engineering company is responsible for receiving orders, delivery and maintenance; Therefore, in addition to the capabilities in structural technology research and development and intelligent manufacturing technology, the barriers to development that assembly interior decoration enterprises will encounter are also factors that need to be considered for assembly technology, such as landing delivery and mass replication. The fabricated technology mainly changes the chemical bonding decoration method into the physical connection method, so it puts forward higher requirements for the connection between various physical structures and the reasonable design in the limited space. Limited by the structure and materials, the basic materials suitable for fabricated interior decoration still need to be rich, and the supply chain system is not perfect, The supporting material manufacturers and professional technicians also need time to cultivate. In addition, the lack of industrial standards, the process to be improved, the immature business model, low consumer awareness and other objective problems are also the difficulties that need to be overcome to improve the penetration rate of prefabricated interior decoration.
