China's 3D prefabricated buildings will account for more than 50 percent of new construction in five years

With the rapid development of science and technology, the construction mode of human production has been continuously upgraded.Since the beginning of the 20th century, the prefabricated building has attracted widespread attention, and in the United States and Europe and other countries to try, reflects the construction speed, low cost of production and other advantages.

In China, prefabricated buildings are still in their infancy, but according to the ministry of housing and urban-rural development, prefabricated buildings will account for more than 20 percent of new construction by 2020 and more than 50 percent of new construction by 2025.As a result, prefabricated buildings will become the focus of the entire construction industry at the beginning of 2019.

It is understood that the so-called "prefabricated building" is a new type of building that combines the new type of prefabricated construction technology and sustainable technology.In terms of construction technology, it adopts the method of systematic design, modular split, factory manufacturing and on-site assembly to build houses, and the industrialized construction method of processing and on-site assembly design in factories.Unlike the "extensive construction" mode of traditional architecture, the prefabricated building is more like "manufacturing" an industrial product. It adopts the assembly line production method to prefabricate the building components, which will be built up like "building blocks" after being delivered to the installation site.The prefabricated building has the characteristics of sustainability, not only fire, insect, moisture, heat preservation, but also environmental protection and energy saving.

At present, China's prefabricated buildings are mainly divided into two categories: "component prefabricated buildings" and "3D prefabricated buildings".Among them, the traditional "component assembly building" is mainly based on beam, board, column, wall and other building components factory production, and then in the construction site for plate assembly.

The so-called "3D prefabricated building" is mainly based on the technology of "3D printed house", which is the overall customized printing of the "single building" in the factory, and finally provides a new building with a highly personalized and more robust and durable than the permanent building through assembly on site.It is worth noting that the global "leader" of this kind of architecture is Beijing huashang luhai technology co., LTD. (hereinafter referred to as "huashang luhai") from China.

So, why did Chinese businessman lu hai's "3D prefabricated building" gain unanimous recognition in the construction field of the world?Previously, some media have seen in the workshop of the Chinese businessman lu hai that the individual buildings printed by the Chinese businessman lu hai, such as dining room, bedroom, kitchen and bathroom, each of which weighs several tons or even dozens of tons, but in the process of assembly, only four lifting points are needed to complete the lifting work of all complex environments...Thus it can be seen that the "3D prefabricated building" printed by Chinese businessman lu hai has amazing high strength!

"The reason why huachang luhai '3D prefabricated building' can achieve such high structural stability is due to a core technology unique to this enterprise in the world!A well-known experts in the construction field in China, told reporters in the field of global construction although there have been many new types of building materials, but almost all the famous buildings are still "reinforced concrete" is adopted to improve the water, this is because the "reinforced concrete in the construction of" integrity, durability, fire resistance, can mould sex is superior to other aspects such as construction materials.In the global field of "3D printed houses", there is only one enterprise that can print raw materials with "ordinary label reinforced concrete", that is the Chinese businessman lu hai from China.

In the future market application level of Chinese businessman lu hai's "3D prefabricated building", the expert also listed several vivid application scenes to the reporter.First, is the vast rural homestead construction market.With the continuous improvement of China's rural living standards, the flipping of homestead has become the most important thing for the current 900 million farmers.Previously, the way of building a homestead, which can only be "overthrown", was revolutionized by the advent of self-upgrading "3D prefabricated building".In the future, each location operator can set the overall structure of the house according to their own requirements. Even after the completion of construction, they can also carry out structural adjustment and adding layers to the house, which will no longer be the case that only "demolition" can be followed by "construction".

Secondly, in the field of tourism real estate, the "3D prefabricated buildings" made by Chinese businessman lu hai will also have great potential.Among them, the more obvious benchmarking is our common "container room".At present, many homestays, tourist attractions and real estate projects are using "container houses" with convenient installation and disassembly, but the insulation, sound insulation and durability of container houses are poor.Therefore, the "3D prefabricated building", which is also convenient for assembly but more suitable for human living needs, will become a direct replacement for the "container house" market.

In addition, the construction of small and medium-sized real estate in cities will also be one of the important markets in the future of "3D prefabricated buildings".Because, based on the customized production in the factory, "3D prefabricated building" can not only greatly shorten the construction cycle and reduce the construction cost, but also in the environmental protection, intelligent upgrading of the building and other aspects, will be unmatched by the traditional "irrigated building".

It is based on such high quality application value and broad market value, in recent years, the governments around the country actively respond to the central policy, have issued a series of supporting "assembly building" related policies.Among them, since 2016, all new civil buildings within the outer ring road in Shanghai should adopt prefabricated buildings, and more than 50% should be built outside the outer ring road.At the same time, Shanghai is also set a certain policy period, the total floor area of more than 30,000 square meters of prefabricated residential projects, prefabricated assembly rate of 40% or more, per square meter can be subsidized 100 yuan, a single project maximum subsidy of 10 million yuan.In nanjing city, jiangsu province, government departments also put forward clear requirements on the proportion of prefabricated building area and prefabricated assembly rate of buildings in the process of land transfer.In Beijing, prefabricated buildings have also been introduced to meet the relevant conditions of housing industrialization projects can be no more than 3% of the planning floor area award.

Thus it can be seen that, as the inevitable future development direction of human building mode -- prefabricated building, we finally see "spring".It remains to be seen how this "spring", called the "3D prefabricated building", will benefit mankind.
