With the continuous progress of science and technology, building materials are constantly changing
.
From civil engineering to masonry to reinforced concrete, people hope to have materials with high efficiency and environmental protection
.
Prefabricated building emerges as the times require and becomes the future Lighthouse of the construction industry
.
So what is prefabricated building? What are the advantages? As the development direction of the future construction industry, prefabricated building is valued for its comprehensive advantages such as high engineering quality, high efficiency, low environmental pollution and good seismic performance
.
It is not only a model of “green construction”, but also represents the innovation of industry technology
.
Prefabricated building has been widely used abroad According to the opinions on promoting the healthy development of the construction industry, the proportion of new prefabricated buildings in new buildings should reach 30% by 2025
.
Quanzhou Municipal government is vigorously promoting the establishment of the “leading group for the modernization of the construction industry” to practice the concept of green sustainable development, and the first prefabricated building “Quanzhou public cultural center library” is a demonstration case of realizing the transformation and upgrading of the construction industry and high-quality development Quanzhou public cultural center – Library real view traditional building is the traditional construction method of pouring reinforced concrete on site
.
Prefabricated building adopts the construction method of factory production Prefabricated partial floor and pouring together with the on-site wall, beam, column after passing the experience
.
On the basis of traditional building, it is optimized and improved to avoid the weak quality control of traditional building, the site is dirty and poor, and there are many consumables The factory and standardized production of prefabricated building components can avoid the error caused by human factors
.
The building components are not affected by weather changes, can be standardized mass production, and the quality is more reliable
.
The traditional construction process produces a lot of construction waste, which consumes a lot of water and pollutes the water source It can be made in the factory manufacturing process
.
There is no fire, no water, no dust, no smell, no welding and cutting, no gauze on the construction site, so as to reduce the construction waste
.
The prefabricated building schematic diagram is coordinated and unified, and the optimized configuration optimizes the building performance and function without reducing the structural safety
.
The comprehensive benefit of the development of green housing is obviously higher than that of the traditional housing system, and it is the national promotion Chongdi green, energy-saving, resource-saving residential assembly building schematic diagram, assembly building seismic poor? Is it easy to pour? The aseismic performance of buildings is mainly affected by shear walls, columns and beams
.
Nowadays, the prefabricated buildings in Quanzhou only provide the laminated plates uniformly processed in the factory, which are poured together with the walls, beams and columns on site, so the aseismic performance is not affected
.
Is prefabricated building easy to leak? Of course not! The quality of prefabricated building composite plate is more controllable, and the anti leakage effect is better than that of manual pouring
.
Is prefabricated building floor thick? The prefabricated floor is only 2-3cm less than the traditional one, and the sound insulation effect is better
.
Note: the floor is not a pure precast floor, but a composite floor
.
Composite floor is a kind of structure combining precast and cast-in-place concrete
.
According to the implementation opinions of Quanzhou Municipal People’s Government Office on vigorously developing prefabricated buildings and the implementation opinions of Shishi Municipal People’s Government Office on vigorously developing prefabricated buildings, the prefabricated building area of commercial residential projects with a total construction area of more than 20000 m2 should reach more than 20%
.
According to the government’s regulations, some of the buildings are built with prefabricated buildings to build the last two new Chinese style residential buildings of high standard for big people
.
The number of seats to be added is limited
