by In recent years, driven by the national policy level and market demand, precast buildings have developed rapidly.
According to the relevant data statistics of the Ministry of housing and urban rural development: at present, precast buildings have accounted for about 30 ~ 40% of the whole construction market.
From the development trend, the market share of precast buildings will rise rapidly.
It should be only a matter of time to completely replace the traditional construction mode.
Recently, the people’s Government of Guangdong Province issued several measures to promote the high-quality development of construction industry in Guangdong Province (YFB [2021] No.
11), which clearly proposed to vigorously develop green buildings, put forward the development path of precast buildings, and build six national demonstration bases + ten provincial demonstration projects.
In August this year, the largest precast building in China, The 24 government affordable housing projects with an area of 1.15 million square meters in Shenzhen have been capped.
The advantages of precast buildings in green environmental protection, energy conservation and high efficiency have long been well known, so this paper will not repeat it.
What this paper wants to discuss and explore are: 1.
The relationship and influence between precast building and precast decoration; 2.
The current situation and outlet of traditional decoration industry; 3.
Analysis on the development of assembly decoration; I.
relationship and influence between precast buildings and precast decoration: the development trend of precast buildings in recent years is indeed in the ascendant, but it is far from reaching the achievements of the whole industrial chain.
As a complete product delivered to users, it should not only be the main structure of buildings, but also include internal and external decoration, indoor water supply and drainage, indoor power lighting, fire fighting, etc, It should even include all elements of home intelligence and end device interfaces.
From the perspective of the precast buildings that have been built and are under construction, it is mainly the industrialized manufacturing and on-site assembly of the main building body.
The internal and external decoration, especially the internal decoration, is still in the exploration and demonstration stage, and mature and perfect standards, processes and methods of precast decoration have not been formed and formulated, which is exactly the problem that needs to be solved urgently.
I was honored to be invited to attend the 10th Guangdong building industrialization exhibition and precast building development forum held in the exhibition hall of Canton Fair in early August 2021.
I also visited the increasingly mature integrated or precast toilets and kitchens.
Through interaction and discussion with many industry experts, I also learned about the development status of precast decoration, At present, it is far from reaching the mature technical level compared with the precast main building, and there are still many problems to be solved.
The relationship between precast main building and precast decoration is the relationship between “skin” and “hair”.
Without skin, hair will be attached.
Now the key question is that “skin” already exists, and how will “hair” be attached? Decoration is the last process of construction.
Only when the decoration project is completed is the complete product delivered to users of the whole construction project.
Now the precast construction technology has become more and more mature, and its share in the market is gradually expanding.
On the contrary, the precast decoration is still groping, demonstrating and hobbling, and can not reach the degree of industrialization, standardization, industrialization and intensification, There are also corresponding and supporting manufacturing and assembly standards, processes, construction methods and technologies to be formulated and issued.
In addition, more importantly, precast decoration must form a unified system with the main body of precast buildings, with organic combination and seamless process connection, and may even be completed on the same production line, so as to finally form a complete whole industrial chain.
II.
Current situation and way out of the traditional decoration industry: it should be said that the decoration industry has also developed rapidly in recent years.
Only ten years ago, there were still many manual paint, manual wood veneer, manual cutting and grinding stones on the construction site, but now all these have been industrialized, which has greatly promoted the development of decoration technology and improved work efficiency.
However, compared with the industries such as the main building and the installation of complete electromechanical equipment, the proportion of manual operation in the decoration industry is still very high, such as wall plastering, ground leveling, stone and ceramic tile paving, etc.
it is basically manual operation.
The uneven individual technology determines the unstable construction quality, long construction period and low efficiency.
In addition, the proportion of wet operation in the traditional decoration industry is high, Affected by the weather, temperature and environment, the author has undertaken a decoration project in Xining, Qinghai.
From November to march of the next year, the average temperature is below minus 10 degrees Celsius.
Wet operation can not be carried out at all.
The effective working days of the whole year are only 7 months, with low efficiency and high cost.
The increase of labor cost year by year also leads to high construction cost.
It can be said that the progress and efforts of the decoration industry in recent years are only low-level and do not cure the symptoms.
In order to fundamentally solve the problem, the only way out is to go through industrialization, standardization and intensification, and the concentrated embodiment of all this is to implement assembly decoration in a large area.
III.
Development Prospect and analysis of precast decoration: compared with the traditional decoration industry, precast decoration is a revolution.
At the 10th Guangdong building industrialization and precast building development forum, some experts even asserted that the traditional decoration enterprises will disappear in ten years! Although this assertion is biased and the author does not agree, it also shows the necessity of reform and the urgency of time.
It can be predicted that after ten years, with the maturity of precast decoration technology, the expansion of market share and the reduction of cost, many traditional decoration enterprises will transform to the upstream of the industrial chain and join the manufacturing and on-site assembly of precast construction industry.
Some decoration enterprises will stay but only do on-site assembly, and the quantities and profits will be greatly reduced, Of course, a large number of decoration enterprises will withdraw from the industry because they can not keep pace with the times and lack core technology and competitiveness.
The reason why assembly decoration is a revolution is that some materials, processes, processes, construction methods and standards of the original traditional decoration will change greatly, and even need to abandon the original standards and re-establish new standards to adapt to assembly decoration..
