Description

Light concrete house system with steel frame and net nest
Technical Field
The invention relates to the field of buildings, in particular to a steel frame net nest light concrete house system.
Background
The development of the building industry in China is extensive for a long time, the weight is not heavy, the consumption of steel, cement and red bricks is high at the first place of the world, and the development of the house industrialization process is still very slow in the first decade after the 21 st century. The consumption of resources and energy resources by the traditional building technology seriously supports the wealth of descendants of the Chinese, meanwhile, with the aging of population and the reduction of fertility, the labor cost continuously rises, and the construction cost continuously rises, so that the international competitiveness of Chinese building enterprises is gradually reduced, which is in sharp contrast with the identity of the large country of the Chinese manufacturing industry. Therefore, the traditional building needs industrial transformation urgently, and the industry is changed to the direction of heavy quality, heavy efficiency, heavy technology, low energy consumption and low pollution.
Under the background of policy code adding and continuous upgrading of building technology, the area and the industry scale of the fabricated building in China are rapidly developed, but the subjective power of the fabricated building development in China is insufficient, and the method mainly comes from two reasons: firstly, the cost of the traditional cast-in-place building mode is still lower than that of an assembly type building, and secondly, the traditional civil construction enterprises and operators are more familiar with the cast-in-place process flow in the construction. The technical improvement of the assembly type building system taking a PC structure (precast concrete member) as the mainstream only considers the assembly of a construction layer, does not fully consider the time and labor cost of each link in the whole production and construction process, only finishes the steps of splitting the traditional cast-in-place building structure into structural members, then carrying out factory production, and then carrying out on-site assembly type installation, but causes the problems of low component standardization, large difference, large volume, long factory maintenance time, long culture period of qualified assemblers and the like, increases the difficulty of design, manufacture, transportation and installation, and increases the building cost on the contrary; the steel structure assembly type building cannot enjoy policy dividend in the years of the rapid development of the housing industrialization in China, and compared with a PC structure, the steel structure assembly type building has the advantages of higher industrialization degree, excellent anti-seismic performance, flexible structure, high housing rate and the like, but the steel structure in China is mainly applied to public buildings and industrial buildings, and the housing construction is less in application and mainly originates from three reasons: firstly, traditional civil engineering construction enterprises are more familiar with concrete technology and steel structure talents are relatively short, secondly, in high-rise residential projects, the price of a building with the same volume is 8% -15% higher than that of a PC structure by adopting a steel structure, and the concrete building is generally considered to be safer than the steel structure by the traditional concept of Chinese people.
