In addition, the prices of raw materials such as steel bars, gravel and cement have risen sharply this year, the sales price of products has not increased significantly, and the operation of precast enterprises is difficult.

Overall, the development of precast buildings in China has gradually expanded from first tier cities to second and third tier cities, showing a development pattern of stepped and layered promotion.

The gradual development of precast concrete components into high-performance parts with function integration and performance improvement is the objective requirement of precast buildings.

Among them, the development and application technology research of high-performance parts are the core competitiveness of prefabrication enterprises.

In addition, the problems of design quality affecting the production and construction efficiency of precast components, the quality and efficiency of production and construction, supply guarantee and inventory coordination, as well as the serious deviation between the product quality and technical services of prefabrication enterprises and the requirements of high-quality construction, the lack of professional technical talents and professional management thinking are all great challenges for the sustainable development of prefabrication industry and precast buildings.

At present, both Beijing and Shanghai have entered the platform period for the development of precast buildings.

Many newly-built small and medium-sized enterprises are facing bankruptcy or conversion of production, and the phenomenon of blind investment in new precast factories has basically ended.

Third, provide internal impetus for the sustainable development of the enterprise through lean production, quality improvement and efficiency increase..

The policy requires that, on the basis of maintaining the current market scale, we mainly focus on the goal of high-quality construction and high-quality buildings, supplement and improve the appropriate construction technology system and product system, strengthen the quality management and personnel training of precast buildings, and tamp the whole process management foundation of the industrialization implementation subject of design, production, construction and installation of precast buildings.

In addition, the low degree of product standardization leads to low production efficiency and high cost amortization, which seriously affects the healthy development of the precast industry in the future.

In this regard, Jiang Qinjian suggested: first, rely on technological and management innovation to continuously develop the application field and potential market of precast concrete.

Many projects still win the bid at low prices, and the market competition is fierce.

Entering the step-by-step hierarchical promotion pattern, “any industry has a process of continuous maturity, and the same is true for the prefabrication industry.” In the face of the current problems, Jiang Qinjian pointed out that although the policy support for the development of precast buildings across the country continues to increase, taking precast buildings as the carrier, jointly promoting the industrialization of intelligent construction and new buildings, and promoting the transformation, upgrading and high-quality development of the construction industry will become the main direction.

At the same time, the promotion of precast buildings in large cities such as South China, southwest and Northwest China is increasing, and some prefabrication factories are still invested in construction.

Second, practice the new concept of building industrialization of energy conservation and emission reduction, quality improvement and efficiency increase, and provide high-quality products and technical services for the high-quality development of precast buildings.

As an important way to combine intelligent construction with new industrialization, to continue to promote the high-quality development of precast buildings, we should continue to promote around technical standards, industry management and the construction of the whole industrial chain of precast buildings.

Relying on technological innovation to develop the potential market, “the future development trend of precast concrete industry is the development and improvement of general technical system and standardized components of precast buildings, and the development and engineering application of precast concrete high-performance components.” When it comes to the next step of development, Jiang Qinjian proposed that the general technical system of precast buildings mainly refers to the two categories of precast frame structure building system and precast shear wall structure building system.

It is suggested to strengthen the research on products and technologies related to resource recycling on the one hand, and strengthen the transformation and upgrading of environmental protection measures on the other hand, so as to ensure the long-term sound development of the plant and the ability of project performance.

Driven by the “double carbon” goal, all component manufacturers should comprehensively improve their awareness of environmental protection, actively evaluate environmental protection risks and project risks, implement environmental protection measures, and solve the relationship between production and construction and environmental protection.

Such products have little technical difficulty in production and low entry threshold.

Jiang Qinjian pointed out that cities with large use of precast components are mainly concentrated in Beijing, Shanghai and Shenzhen.

Blind low-cost competition in some new factories to seize the market is very common.

PC manufacturing enterprises should strengthen technological innovation and increase the research and development of new technologies, new processes and new materials.

All parts of the country should develop standardized components and parts system around structural system, enclosure system, equipment system and decoration system to form an economical and applicable standardized product series.

The development of the industry is facing challenges.

In the process of improving and promoting the development policy of precast buildings in the second and third tier cities, the promotion and application of the fourth and fifth tier cities and the vast rural areas is still in the pilot exploration stage, mainly focusing on the application of some standardized components and parts, and taking the road of industrialized construction with low prefabrication rate.

Precast concrete components in these areas are mainly concentrated in the field of precast housing.

Promoting the development of building industrialization and precast buildings according to local conditions is an important means of building transformation and upgrading in the future.

In most areas, they are mainly horizontal components such as laminated plates and stairs.

Spread Anchor

Jiang Qinjian said that both Beijing and Shanghai have played an exemplary and leading role in terms of implementation scale and technical quality management level.

The increment of precast component market is limited, and the production capacity of precast enterprises is seriously insufficient.

With the promotion of green low-carbon building materials and green construction methods, accelerating the industrialization of new buildings, vigorously developing precast buildings and promoting the top-level design of steel structure houses, how will the precast concrete industry develop in the future? Facing the existing problems and challenges, how will the industry respond? In this regard, Jiang Qinjian, President of Beijing precast building engineering research institute, said that in the first year of the 14th five year plan, the main focus is on the improvement of high-quality construction, building industrialization and steel structure construction of precast buildings, marking the industry’s trend to focus on promoting the stage of quality improvement, efficiency and sustainable development of precast buildings.
