Description

Column foot piece for assembled light mixed structure

Technical Field

The utility model relates to a building element especially relates to a column base spare that is used for light structure of mixing of assembled.

Background

In recent years, China has developed a series of policies to promote the rapid development of housing industrialization and building industrialization. The 'twelve five green buildings and green ecological region development plan' printed by the residential building department in 2013 firstly and definitely puts forward the accelerated formation of industrialized building systems such as fabricated concrete, steel structures and the like in China, the state department puts forward about 10 years of national force contention in 2016 so that the proportion of fabricated buildings to the newly built buildings reaches 30%, and the residential building department in 2017 further and definitely puts forward the proportion of fabricated buildings to the newly built buildings which accounts for more than 15% in 2020 all the country. In addition, a plurality of assembly type building construction and evaluation standards are issued one after another, matching policies are issued one after another in various provinces and regions to support the promotion of assembly type building implementation, the proportion target of the assembly type building in a newly built building is determined, and meanwhile, relevant subsidy and preferential policies are proposed.

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 assembled building, and secondly, the traditional civil engineering 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.
