Information
Since the beginning of the 20th century, people have paid more and more attention to prefabricated buildings, which have shown the advantages of fast construction speed and low production cost.
 
At present, the prefabricated building is still in its infancy, but according to the outline for the modernization development of the construction industry issued by the Ministry of housing and urban rural development, it is planned that by 2020, the proportion of the prefabricated building in the new building will be more than 20%, and by 2025, the proportion of the prefabricated building in the new building will be more than 50%. In the short term, prefabricated buildings begin in 2019 and become the focus of the whole construction industry.
 
It is understood that the so-called "prefabricated building" is a new type of building that combines new prefabricated construction technology and sustainable technology. In terms of construction technology, the mode of systematic design, substitution, factory manufacturing and on-site assembly is adopted, which is the "extensive construction" mode of typical traditional buildings. It is more like "manufacturing" an industrial product. The mode of assembly line production has the characteristics of sustainability, not only fire prevention, insect prevention, moisture-proof, heat preservation, but also environmental protection and energy saving.
 
At present, the conventional prefabricated buildings are mainly divided into "component assembly building" and "3D assembly building". Among them, the traditional "component assembly building" is mainly composed of beams, plates, columns, walls and other building components, which are manufactured in the factory, and then assembled in the construction site. This kind of technology, door solution and assembled building have some hidden dangers in seismic resistance. Before that, the merging media exposed that "component assembly building" had problems such as wall cracking, uneven joint of plates, poor sound insulation effect and poor heat insulation effect. Therefore, this kind of assembly building method has not been expanded.
 
(the "component assembly building" is not popular due to frequent quality problems)
 
The so-called "3D prefabricated building", which combines the latest building technology, has attracted wide attention in the field of construction in various countries due to its better seismic performance and multiple application advantages. It is reported that the so-called "3D prefabricated building" is mainly based on the "3D printing house" technology, with the overall customized printing of "single building" in the factory, and finally through on-site assembly, so as to provide residents with a new building with a high degree of personalization and stronger and durable than the permanent building. It is worth noting that the global "leader" of this construction method is Beijing Huashang land and Sea Technology Co., Ltd. (hereinafter referred to as "Huashang land and sea") from China.
 
(Chinese land and sea "3D prefabricated building")
 
So, why does the "3D assembly building" of Chinese land and sea obtain the unanimous recognition in the construction field of all countries in the world? Vertically, some media once saw in the factory buildings of Chinese merchants, such as restaurants, bedrooms, kitchenware rooms and other single buildings printed by Chinese merchants, each with a weight of several tons or even dozens of tons. However, in the process of assembly, only four lifting points are needed to complete the lifting work in all complex environments It can be seen that the "3D prefabricated building" printed by Chinese businessmen on land and sea has an amazing high strength!
 
"The reason why Chinese land and sea '3D prefabricated buildings' can achieve such high structural stability is due to a unique core technology of this enterprise in the world!" A well-known expert in the field of architecture told reporters that although new building materials have appeared in the field of architecture around the world, almost all well-known buildings still use "reinforced concrete" for pouring, because "reinforced concrete" in the integrity of the building, stress, fire resistance, but in the world“ In the field of 3D printing house, there is only one enterprise that can print raw materials with "ordinary reinforced concrete", followed by Chinese businessmen from land and sea.
 
It is based on such a unique global core technology that Chinese businessmen print“ 3D prefabricated building not only achieves the structural stability that other "prefabricated buildings" can't reach, but also solves a series of problems that often appear in "component prefabricated buildings", such as wall cracking, uneven wood seam, poor sound insulation effect, poor heat insulation effect, etc.
 
In the future market application scale of "3D assembly building" of Chinese land and sea, the expert also gave reporters several distinct application scenarios. First of all, the vast rural residential base construction market. With the continuous improvement of rural living standards, the turnover of homestead has become the most important thing for 900 million farmers. Before that, only "overturning the re built" homestead construction mode, because of the continuous self upgrading "3D assembly building" came out and produced subversive transformation. In the future, every location owner can set up the overall structure of the house according to their own requirements. Even after the construction is completed, they can also adjust the structure of the house and add floors. There will be no longer a situation where the house can only be "demolished" before "built".

In fact, in the field of tourism real estate, the "3D prefabricated buildings" made by Chinese businessmen on land and sea will also have great potential. Among them, what is more distinctive is our common "container house". At present, there are many domestic accommodation, tourist attractions and real estate projects are using the convenient "container house", but the insulation, sound insulation and continuity of the container house are poor. Therefore, the "3D prefabricated building", which is convenient at the same time, but more suitable for human living needs, will become a direct replacement of the "container housing" market.
 
("3D prefabricated building" is expected to replace "container house")
 
In addition, the construction of small and medium-sized real estate in the city will also be one of the important markets of "3D prefabricated building" in the future. Because the "3D prefabricated building" based on customized production in the factory can effectively expand the construction cycle and reduce the construction cost. At the same time, in terms of environmental protection, intelligent upgrading of the building, etc., it will also be incomparable to the traditional "pouring building".
 
It is based on such high-quality application value and broad market value, subdivision, the national governments actively respond to the central policy, have issued a series of supporting "prefabricated building" related policies. Among them, since 2016, all new civil buildings within the outer ring road should be prefabricated buildings, with the outer ring road more than 50%; at the same time, Shanghai has also set a certain policy period, the total building area of more than 30000 square meters of prefabricated residential projects, which are reasonably installed in Nanjing, Jiangsu Province. In the process of land transfer, the government departments have also used to Proportion and in Beijing, it has also introduced that housing industrialization projects that use prefabricated buildings to meet the relevant conditions can receive no more than 3% of the planned building area award.
 
It can be seen that as the inevitable development direction of human architecture in the future, prefabricated building has finally ushered in a more trustworthy era of "3D prefabricated building" after going through the stage of "component assembly building" with different praise and criticism. In human history, we can clearly see that no matter the change of the times or the upgrading of production technology, it will go through a process of "trial and error → maturity". Fortunately, in the field of "prefabricated architecture", we have finally seen "spring". What kind of well-being can this "spring" called "3D assembly building" bring to mankind? We will see!
