SPCs technology and BIM application can drive the industrialization of the industrial chain of building electromechanical installation, decoration and smart home, reconstruct the new ecology of the construction industry, and realize low-carbon and high-quality development|| Source: China Construction daily original title: promoting the development of precast buildings and accelerating the application of innovative technology statement: national policy evaluation is committed to the original and selected content in the fields of real estate, land, evaluation, finance and so on..

Promoting the “integration of industrialization, digitization and greening” and promoting the rapid development of precast buildings is an important direction for the transformation and upgrading of the industry in the future.

   from the perspective of practice, we must focus on “whole process Industrialization” to make precast buildings really give full play to the effect of energy conservation and emission reduction.

  to promote the sustainable and healthy development of precast buildings, we must return to the original intention of the development of building industrialization: the adoption of industrialization evaluation standard system will greatly reduce on-site construction, reduce labor and reduce energy and resource consumption, and can not “assemble for assembly”.

Building energy consumption is mainly in the material production and operation and maintenance stage, and the carbon emission in the construction stage accounts for only 1%, but this does not mean that the construction stage is not important, because the construction quality determines the energy conservation and emission reduction effect in the later operation and maintenance stage.

Digital application should run through the whole process of precast buildings.

   independently research and develop the structural technology system of “cavity overlapping plus post pouring and shaped mold pouring joints”, pursue “full prefabrication of walls, columns, beams and slabs + full assembly above and underground”, and solve the pain points of structural safety, water leakage, external wall insulation, shortage of industrial workers and high cost of precast buildings, which is in line with building energy conservation and high-quality development.

Precast building precast building is an important starting point to achieve the goal of “double carbon”.

  government departments are important promoters of the development of precast buildings.

The digital model should not only enable the whole process of production and guide the construction, but also serve the energy conservation and carbon reduction in the operation and maintenance stage.

Promote the development of new technologies for precast buildings   from the perspective of the whole process, emphasize returning to the original intention of the development of building industrialization, emphasize the application of technological innovation, “take building as a product and construction as manufacturing”, focus on the main structure of concrete buildings, provide systematic solutions for the industrialization of the main structure with SPCs, and move towards intelligent construction through building industrialization, Realize the low-carbon development of the construction industry and obtain wide recognition inside and outside the industry.

  the state and industry competent departments should encourage greater investment in scientific and technological research and development and new product development, take the lead in establishing authoritative evaluation institutions and cultivating talent teams, and promote the healthy and rapid development of precast buildings; We should encourage and guide the development of advanced cast structure technology system, and provide policy support for the problems existing in the promotion of new technologies, so that cast buildings can truly guide the green and low-carbon development of the construction industry.

0 has five types of intelligent equipment of Sany construction engineering, two types of standards for building structure and construction, intelligent design software, industrial software for intelligent analysis of three-dimensional model driven automatic operation of equipment, SaaS (providing software services through network) software based on BIM (building information model) and other three types of software and full cycle and full elements Full role real-time online project collaborative management platform, with core competitiveness leading the industry.

On the other hand, we should deeply combine the two majors of architecture and structure, formulate reasonable energy conservation and emission reduction targets from the scheme design stage, clarify the selection of environmental protection materials, layout of house types, application of new technologies, etc., and give full play to the advantages of precast buildings under the guidance of green energy conservation.

Combined with the actual development of enterprises, it is proposed that to promote the healthy and rapid development of precast buildings, we must return to the essence of industrialization, promote green construction in the whole process of engineering construction, and accelerate the application of innovative technology.

During the 14th Five Year Plan period, the sustainable and healthy development of precast buildings is not only related to the overall situation of high-quality development of the construction industry, but also determines the green development of the construction industry.

Through the application of new technologies, the quality of housing can be improved and the popularization of higher energy-saving standards can really benefit the development of all parties.

However, at present, the thinking concept of industrialization, industrialization and systematization of the construction industry has not been fully established, and all links are separated to a certain extent.

As a transition scheme of “full prefabrication and full assembly”, it has an absolute competitive advantage.

At the same time, compared with focusing on a certain stage, we should think about how to minimize energy consumption in the whole life cycle of the building.

The policy score is high and the cost is close to the cast-in-situ aluminum formwork.

While continuously improving the assembly rate, they should mobilize the enthusiasm of all parties.

It is necessary to continuously optimize the construction process to ensure the low-carbon and green of subsequent operation and maintenance.

It is far superior to traditional buildings in terms of green, low-carbon, energy conservation and emission reduction.

In recent years, the state has been promoting the development of precast buildings.

  in addition to technical investment, the construction of digital platform is also very important.

Assembly rate is one of the important indexes to evaluate the degree of assembly of precast buildings, which is of great significance for the promotion of precast buildings.

The development of precast buildings focuses on “whole process Industrialization”   the characteristics of precast buildings are “standardized design, factory production and assembly construction”, which has the attribute of “green and low carbon”.

The “vertical high prefabrication and assembly + horizontal industrialized post pouring” scheme of SPCs greatly reduces the on-site operation of reinforcement, formwork and scaffold.

However, in the development of precast buildings, there are deviations in the understanding of assembly rate in some areas, and the phenomenon of “water drainage” appears in actual operation, resulting in the emergence of “camouflaged matched buildings”.

On the one hand, we should change the thinking that “the construction stage makes little contribution to energy conservation and carbon reduction”.

  abandon the development idea of “assembly for assembly”   at present, in order to speed up the development of precast buildings, many regions take the assembly rate as the main index for formulating supporting policies, and give certain preferential support to “up to standard” enterprises and projects.
