With the progress of society, people's requirements for housing are becoming increasingly high. From the previous adobe houses to the current prefabricated light steel houses, technological progress has led people into the housing 5.0 era. The country is also vigorously promoting the development of green prefabricated light steel houses. Subsidy policies have been introduced in various regions, and prefabricated light steel has ushered in a new trend, subverting people's lives
On April 2nd, the reporter learned from the Changsha Municipal Housing and Construction Bureau that recently, the Changsha Municipal Housing and Construction Bureau and the Changsha Municipal Finance Bureau jointly issued the "Implementation Rules for Financial Subsidies for Prefabricated Buildings in Changsha City" (hereinafter referred to as the "Implementation Rules"), which clarifies that for newly built prefabricated commercial housing projects in Hunan Xiangjiang New Area, Changsha High tech New Area, and Inner Five Districts that meet the subsidy conditions, the construction unit will be given a subsidy of 100 yuan/square meter. The Implementation Rules shall come into effect on April 15th and be valid for 5 years.
According to the Implementation Rules, the subsidy scope mainly includes newly-built prefabricated commercial housing projects that meet the subsidy conditions in Hunan Xiangjiang New Area, Changsha High tech Zone, Furong District, Tianxin District, Kaifu District, Yuhua District, and Yuelu District.
The subsidy target is the project construction unit, with a subsidy standard of 100 yuan/square meter. The subsidy area is calculated based on the sum of the single building capacity areas that meet the assembly rate requirements.
According to the Implementation Rules, if the requirements for prefabricated buildings are not clearly stated in the land listing conditions, the construction unit shall actively adopt prefabricated building technology for construction, and the assembly rate of individual buildings shall be above 50% (inclusive); In addition, the requirements for prefabricated buildings have been clearly stated in the land listing conditions, and the construction unit has actively raised the assembly standards. For newly built commercial housing projects with a single building assembly rate of 60% or more, after the completion acceptance of the project and the recognition of the Municipal Housing and Urban Rural Development Bureau, the project construction unit can submit a written application for prefabricated building financial subsidies and relevant supporting materials to the district housing department where the project is located.
The Implementation Rules also have clear requirements for subsidy deadlines: projects that obtain land use rights before January 1, 2018 and complete completion acceptance between January 1, 2018 and December 31, 2019; Projects that obtained land use rights between January 1, 2018 and December 31, 2019, and completed project completion and acceptance before December 31, 2021.
Statistics show that in 2018, Changsha implemented a total area of 6.97 million square meters of prefabricated housing construction and municipal projects, accounting for 30.8% of the newly built construction area, achieving a prefabricated building output value of 45 billion yuan, and hosting the "Construction Expo" for the third consecutive year. As of now, the city has 9 national level bases for prefabricated buildings and 9 provincial-level bases (excluding national level). The production capacity, scale, and development speed of prefabricated buildings are among the top in the country, and the "leading effect" is gradually emerging.
The relevant person in charge of Changsha Housing and Construction Bureau introduced that this year, Changsha Housing and Construction Bureau will carry out the "Prefabricated Building Industry Year" activity. In addition to issuing financial subsidy rules for prefabricated buildings, it will also encourage and support the promotion of prefabricated buildings in Changsha County, Wangcheng District, Liuyang City, and Ningxiang City, fully leveraging the technical support role of "one alliance, one base, and three centers", and striving to achieve a 35% proportion of prefabricated buildings in new construction in the central urban area.
This latest type of house is a progress of the times and a development of technology
70年代前
Due to the backwardness of productivity, there were still a large number of adobe houses in China before the 1970s. A adobe house is a house with mud walls. On the basis of clay, reinforced materials such as wood fibers from cedar, dog grass, straw, and bellflower stalks are added to form the wall. Now young people roast that they are poor enough to eat dirt, but dirt was a house in the past!
70年代末
China learned construction technology from the Soviet Union, and finally used bricks to build houses, no longer worrying about mice digging holes in corners. However, not everyone can afford to live in a brick house, and housing is all allocated by enterprises and institutions. Scarce housing resources, dozens of families living together in cramped spaces, so everyone calls it a tube house. The long corridor connects various units, and the bathroom and toilet are shared. Young people can't imagine the days when someone would use the restroom next to stir frying dishes here, which was already quite good at that time.
80年代
Waiting for the country to build houses, relying on organizational allocation of houses, and asking units to provide houses "was a popular housing phrase in the 1980s. The real estate sector still belongs to the national planned economy, and all urban land is actually under the control of the state and government. The government builds houses and distributes them to the people for living, which is commonly referred to as "public housing". Public housing will give priority to married families, so you understand why the older generation always urges marriage. At that time, if I wanted to be a dignified single dog, I might not even be able to find a place to live!
90年代
The market economy has penetrated into society, and the welfare housing distribution system has stopped. China has entered the era of commercial housing, and single dogs can finally earn money to buy houses on their own. Driven by strong demand and favorable benefits, the real estate industry has entered a stage of rapid development. At that time, housing prices were still at a low level. If fathers had enough vision to buy two more houses, their current life would be so happy that it's hard to imagine~
2000年
The market economy has matured, and property prices are outrageously high. A toilet can be sold for hundreds of thousands of yuan by area. Dwelling in cramped spaces has become a common phenomenon, and the government has quickly introduced regulatory policies. Moreover, cities are becoming crowded, pollution is severe, and buying a house is becoming less and less a wise choice. On the other hand, rural infrastructure is becoming increasingly sophisticated, the urban-rural gap is narrowing, and people are more willing to return to their hometowns to build houses. Due to technological limitations, self built houses in rural areas are still mainly made of bricks, stones, and cement.
2010年后
Economic development brings about a comfortable material life, at which point people begin to care about health and environmental issues, and national policies also lean towards sustainable development. The solid clay bricks used in brick houses require a large amount of clay, which damages farmland, consumes coal, and pollutes the environment.
Therefore, the Ministry of Construction of China issued a notice on further strengthening the prohibition of the use of solid clay bricks, and instead vigorously supported more advanced prefabricated buildings. So a new type of housing with superior performance has brought a different surprise to many people, which is light steel prefabricated housing.
The overall goal of the comprehensive deepening of reform and the construction of new urbanization in 2013 has put forward new requirements for the transformation and development of the construction industry. In this period of great change, green development has become increasingly clear as one of the transformation directions. Prefabricated buildings can improve construction efficiency, enhance building quality, low-carbon energy conservation, and meet the requirements of sustainable development.
The vigorous development of light steel buildings is not accidental. In North America, Europe, Australia and other places, light steel villas have already developed very maturely. Light steel villas have been widely adopted in developed countries and are known as the main representatives of green buildings.
The construction technology of lightweight steel structure low rise residential buildings has evolved from the North American timber structure construction technology. After more than a century of development, it has formed excellent physical properties, flexible space and form. The most important thing is that it meets the diverse housing needs of the people.
Light steel villa sound insulation
The national standard for sound insulation is 40 decibels, but most traditional houses cannot meet this standard Poor sound insulation effect, seriously affecting the quality of life! Light steel houses are composed of light steel keel insulation materials and structural panels. The composite wall has a sound insulation effect of up to 60 decibels, making it easy to enjoy high-quality living!
Light steel villa thermal insulation
The insulation effect of brick and concrete building materials is poor. It is hot in summer/cold in winter Most roofs add half a layer for insulation, which also increases costs. However, the composite wall of light steel houses avoids the "cold bridge" phenomenon of the wall, and a 15cm composite wall has the same insulation effect as a 1-meter brick wall.
Light steel villa design Diverse shapes Large usable area
Traditional rural houses do not have professional designers to design them, and their appearance is similar. The structural layout is not suitable and aesthetically pleasing, and the usable area can only reach 75% -80%. The unique materials of light steel houses can be flexibly assembled, providing possibilities for achieving various styles of building shapes and making them rich The diversified architectural appearance is fully reflected in the thickness of the walls of light steel structure houses, which is generally 12cm-20cm, and the usable area can reach more than 90%.
Light steel villa seismic resistance
Light steel structure residential buildings have a light weight, good seismic performance, and can withstand earthquakes of magnitude 9. Due to the lateral and vertical movement of earthquakes, a light steel structure connected by screws forms a safe and stable box, which will not cause wall collapse or floor slabs to fall and endanger personal safety due to earthquake shaking. From a seismic perspective, light steel structures greatly outperform brick and concrete structures. No one can predict the occurrence of disasters, but they can be prevented from happening. From the perspective of seismic safety, more and more people are choosing light steel buildings.
Living and working in peace and contentment "is a beautiful aspiration of humanity. There is also an increasing demand for higher living standards among people, who are more concerned about the comfort, aesthetics, and energy efficiency of housing. Light steel prefabricated housing perfectly meets the needs of contemporary people, subverting traditional housing forms and becoming the choice of more and more people.
