Information
In 2016, the central government of the Communist Party of China issued several opinions on improving urban planning and construction management. In the future, it will focus on the three major urban agglomerations of Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta, and vigorously promote prefabricated buildings. In about 10 years, the proportion of prefabricated buildings in the new building area will reach 30%.
It can be predicted that in 2019, prefabricated buildings will be the focus of construction work in all regions. In this favorable environment, how should construction enterprises understand "prefabricated building" and choose "prefabricated building"?
 
"Assembly building" will become the general trend of domestic construction industry
From the perspective of foreign scope, prefabricated buildings have shown a rapid development trend. According to the statistics of relevant foreign organizations, up to 16% of the newly built houses in Japan are prefabricated buildings, while 80% of the houses in Sweden are totally or partially. In addition, the United States, the United Kingdom, Singapore, Hong Kong and other countries and regions have also begun to work on "prefabricated buildings".
In the past few years, due to the favorable market environment and the low cost of employing people, the mode of construction and production has been in a conservative state. The construction industry also presents the characteristics of "high growth rate, scale, multiple opportunities, low profit, old mode and constant profit".
Fundamentally, the "aging" of the construction engineering population and the continuous improvement of the government's requirements for "building environmental protection" and other aspects, the traditional building mode has gradually changed, and gradually, "assembly building" has become a new direction of the production mode of the construction industry.
 
According to this, since 2016, local governments have increased policy support and subsidies for "prefabricated buildings". According to incomplete statistics, up to now, 32 provinces and autonomous regions have issued support and subsidy policies for "prefabricated buildings". Among them, Guangdong and Jiangsu, which are two strong economic provinces, have made it clear that the "assembly building projects that meet the conditions and implementation standards" have been identified. In addition to the project subsidies of 1.5-2.5 million, Beijing, Shanghai, Tianjin, Chongqing, Zhejiang, Hebei, Shandong and other provinces and cities have also made it clear that the "assembly building" that meets the conditions and implementation standards has been identified ”For the project, support and subsidies will be given, including financial incentives, tax relief, and floating of the amount of provident fund.
 
It can be seen that the trend of "assembly building" has become inevitable, but we should also pay attention to "meet the conditions and implementation standards" is the development and fundamental of "assembly building"!
The quality level of "assembly building" is not uniform, "3D assembly building" or the best solution
In general, "prefabricated building" has the advantages of function, high efficiency, energy conservation and environmental protection. At present, the "component assembly building" is widely used in the industry, including beam, plate, column, wall and other building components factory production, and then plate assembly in the construction site. The most common problem of this kind of door microbial integrated building production mode is actually the on-site assembly and exchange, and the contradiction of component installation quality control. If the installation quality control is not in place, and the accuracy is deviated, then the further hoisting of the component will multiply the error, and the error can hardly be adjusted. The final result is that the component is not installed in the correct position It can not really reflect the superiority of the quality of prefabricated buildings, but also increase the construction cost.
 
"A building needs tens of thousands of pieces of assembled components. If the construction personnel make a little mistake in operation, it will cause 'irreversible' loss!" An expert in the field of construction told reporters that "component assembly building" can be described as a combination of advantages and disadvantages, with high expectation rate and reduced on-site workload, which is good; but it increases the workload and reliability requirements of component connection, and increases the construction cost, which is a disadvantage.
Similarly, "3D assembly building" based on 3D building printing technology can effectively avoid the construction hidden danger of "field assembly" conversion, truly reduce the field workload, and promote the connection reliability of "assembly building".
 
When it comes to "3D assembly architecture", we have to mention an enterprise from China - Beijing Huashang land and Sea Technology Co., Ltd. It is reported that, as the only enterprise in the world that can print raw materials with "ordinary reinforced concrete" and produce "spray head" of 3D printer that can spray out "large particle heavy aggregate concrete" with stones, Chinese businessmen, land and sea, take the lead in realizing the commercialization of "3D printing house" in the world.
 
In 2018, Chinese businessmen on land and sea actively responded to the call of the state to vigorously advocate "prefabricated building", based on their rich construction experience in "3D printing house", and launched a more reliable and convenient "3D prefabricated building".
 
It is understood that, unlike the traditional "component assembly building", the main production mode of building components is beams, plates, columns, walls and so on“ 3D assembly building is based on kitchen, living room, bedroom and other "single volume, at least have all the industrial advantages of" assembly building ", at the same time, it can reduce its" field assembly "quality hidden dangers caused by operational errors.
 
(the main components of "3D prefabricated building" are kitchen, living room, bedroom and other "single buildings")
 
In terms of product quality, the "3D assembly building" of Chinese land and sea can not only optimize the structural density of the building and enhance the building strength in the construction process, but also expand the bearing area of the single building and enhance the stability of the overall building in the assembly process by the concept of "horizontal use".
 
(the "vertical construction" can consolidate the structural density of the building and enhance the building strength)
 
("transverse use" enlarges the stressed area of single building and enhances the stability of the whole building)
 
In the upper part of the assembly, based on the technical advantages of Chinese land and sea "ordinary reinforced concrete" as the building raw materials, these "single buildings" of several tons or even dozens of tons each need only four lifting points to complete the lifting work. At least, it can more intuitively show the "3D prefabricated building" and its reliable structural strength, and at the same time, it can reduce the assembly accuracy on site and save the assembly cost.
 
(only four lifting points are needed for the "3D assembly building" of Chinese land and sea enterprises to complete the assembly work)
 
It is by virtue of the above product advantages that the "3D assembly building" of Chinese land and sea has won the attention and orders of many provincial government departments and construction enterprises as soon as it is launched. In the scenes of facilities, rural housing construction, urban small and medium-sized apartments, tourism real estate projects, we can feel the convenient, environmental protection and reliable industrial value of "3D assembly building".
To sum up, the development of any industry is a process of continuous self upgrading. In the field of "prefabricated building", the "3D prefabricated building" of Chinese land and sea is the latest best solution in this field. For the construction industry, in the expectation that the government will increase the support and supplement of "prefabricated building", all construction enterprises will enhance the purchase demand of "prefabricated building". However, it should be noted that the quality of building is an insurmountable "red line" no matter when and where! Therefore, how to choose the most reliable "prefabricated building" is believed that the decision makers of each construction enterprise will have a very rational judgment.
