by 1、 Survey on the production status of prefabricated building components in Shanghai 1 general overview of prefabricated building components factories in Shanghai with the promotion of prefabricated building projects, the production capacity of prefabricated building components in Shanghai continues to increase, and the production capacity of prefabricated building components in Shanghai increases rapidly.
With the large-scale implementation of the project, the confidence of industrial units has been greatly boosted, and the pace of transformation and development has been actively accelerated.
Many enterprises have established prefabricated building R & D centers.
From the end of 2014, the production capacity met the demand of 1.8 million square meters of prefabricated building components, increased to nearly 5 million square meters by the end of 2015, and exceeded 12 million square meters by the end of 2016.
As of May 2017, the design capacity has reached 15 million square meters.
Under the background that the Ministry of housing and urban rural development cancels the market access of prefabricated component manufacturing enterprises, it actively explores the management mode of combining administrative supervision and industry self-discipline.
The notice of Shanghai housing and Urban Rural Development Administration Committee on printing and distributing the provisions of Shanghai on the supervision and management of the use of construction materials (HJG [2015] No.
726) specifies that the industry association shall record and register the component manufacturing enterprises and their product flows, Give full play to the role of industry self-discipline management.
Reasonably guide the production capacity of prefabricated components, timely release the construction plan of prefabricated buildings in Shanghai, the layout and production capacity data of existing prefabricated component plants, and ensure the supply and demand balance of the prefabricated component market in Shanghai.
As of June 2017, there were 52 registered enterprises, including 29 local enterprises, accounting for 56% of the total, 23 foreign enterprises, accounting for 44% of the total, including 13 enterprises in Jiangsu Province, accounting for 25% of the total, and 10 enterprises in Zhejiang Province, accounting for 19% of the total The capacity of prefabricated components can basically meet the demand of projects under construction in this city.
As for the auxiliary materials (sleeves, grouting materials and connectors) of prefabricated components, as of 2016, there were 20 sleeve, grouting materials and connectors enterprises in Shanghai.
Among them, there were 3 sleeve enterprises, 3 grouting material enterprises and 2 connector enterprises in the city.
There were 8 sleeve enterprises, 5 grouting material enterprises and 9 connector enterprises in other provinces and cities.

2 Introduction to typical prefabricated components and supporting research enterprises in Shanghai the research group conducted research on typical prefabricated components in Shanghai in combination with the research outline.
The research enterprises include prefabricated component enterprises such as Shanghai urban construction materials port side prefabricated building parts production project, Baoye residential engineering Qingpu prefabricated component production project, The brief introduction of the enterprise is as follows: 1 Shanghai urban construction materials production project of prefabricated construction parts near the port tunnel Co., Ltd.
Shanghai urban construction materials is a wholly-owned enterprise with the integrated development of “three-dimensional” industry, with the R & D, production and sales of commercial concrete and new building materials as the basic industry, green environmental protection, new energy-saving building materials and e-commerce as the supporting industry, and science and innovation as the leading industry.
The annual sales volume is more than 2 billion yuan.
At present, it has the highest qualification for the production of concrete prefabricated components and commercial concrete.
The whole process of production and sales is controlled by ISO9001 quality assurance system, ISO14000 environmental management system and OHSAS18000 occupational health and safety management system.
The company has a municipal enterprise technology center.
It is a high-tech enterprise in Shanghai, a civilized unit in Shanghai, a winner of concrete components in Shanghai, and an excellent company in the merit competition of key projects in Shanghai.
The company has eight professional commercial concrete companies, four professional branches for production and processing of assembled prefabricated components, the most advanced PC automatic production line in China, and has mastered the advanced production technology of various concrete prefabricated components.
The main products include ready mixed commercial concrete, ready mixed commercial mortar, dry powder mortar, facing concrete wallboard (PC board), bridge deck, tunnel segment, square pile, high-strength reinforced concrete protective layer positioning parts and other municipal and architectural concrete and products, which have been recognized by the American PCI Concrete Association and the Japanese JIS standard testing center.
It is the first concrete prefabricated component enterprise in China to obtain the certification qualification of the Japanese PC Association.
The company’s “PC prefabricated concrete components” and “desulfurized gypsum inorganic insulation mortar” won the title of famous and excellent products in the building materials industry in Shanghai.
The company has established a strategic partnership with Shanghai Vanke Real Estate Co., Ltd.
for the production of PC boards in China, becoming the first designated enterprise for the production of PC boards.
The Lingang branch of urban construction materials currently has a newly built prefabricated component production line with international advanced level, with a designed annual capacity of 1.5 million square meters.
It has been selected into the “2016 science and technology project plan prefabricated building science and technology demonstration project” of the Ministry of housing and urban rural development and the “2016 top ten enterprises in the production of prefabricated concrete components for housing construction” of the prefabricated concrete component branch of China concrete and cement products association.
The main products include prefabricated ordinary exterior wall panels, laminated floors, sandwich insulation exterior wall panels, etc.
The main demonstration contents are: optimize the imported Finnish full-automatic PC production line, which can produce special-shaped components and improve production efficiency; Component information management is realized through RFID chip implantation.
