Booming precast concrete building construction industry
As one of the key areas for the development of assembly building in the country, our province focuses on optimizing the layout of prefabricated component manufacturing enterprises and actively promotes the coordinated development of Beijing, Tianjin, and Hebei, which not only promotes the transformation and upgrading of the construction industry, but also prevents the formation of With the new overcapacity, the prefabricated component industry has shown a good momentum of vigorous development.
21 base companies have technological and industrial advantages
Our province will develop prefabricated buildings as a major task in realizing the transformation and upgrading of the construction industry, and encourage relevant enterprises to transition to component manufacturing enterprises. At present, there are 57 prefabricated component manufacturing enterprises in our province (some enterprises have both precast concrete component production lines and steel component production lines) and 151 production lines. Among them, there are 21 precast concrete component production enterprises, 48 production lines, annual designed production capacity of 2.03 million cubic meters, 40 steel component production enterprises, 101 production lines, annual design capacity of 2.67 million tons, 2 wood structure production enterprises, and 2 production lines. Annual design capacity of 20,000 cubic meters. Compared with last year, the number of prefabricated component manufacturers and their production capacity have both increased substantially. Among them, there are 8 prefabricated concrete component production companies with an increase in production capacity of 1.14 million cubic meters, and 14 steel component production companies with an increase in production capacity of 530,000 tons. The number of wood structure production enterprises increased by 1 and the production capacity increased by 10,000 cubic meters.
In terms of base enterprise construction, there are 21 base companies in our province, including 5 national and 16 provincial-level assembly construction industry bases, covering prefabricated components, building components, new wall materials, equipment manufacturing, integrated housing and municipal facilities. And other fields. Among them, Qinhuangdao Alpha Industrial Park Development Co., Ltd. and Hebei Hechuang Building Energy-saving Technology Co., Ltd. are representatives of PC companies. Jidong develops integrated housing and Hebei Construction Group has technological and industrial advantages in the field of steel structure construction. Big Tree Industry in Qian’an City The CLT assembled wood structure technology of the limited liability company is at the leading level in China. The Xindi Land Company in Shijiazhuang and the Xuelong Company in Xinji are precast concrete member production equipment manufacturing enterprises that have a certain influence in the country. At present, there are more than 80 companies. More than 100 production lines use the equipment of the new earth company.
To undertake the function of Beijing's non-capital functions, especially the establishment of the Xiong'an New District, has brought about historical opportunities for the province to vigorously develop prefabricated buildings. At present, there are 36 prefabricated components manufacturing enterprises in the Beijing-Tianjin region, including 6 in Baoding, 20 in Tangshan, 4 in Zhangzhou, 2 in Langfang, 1 in Chengde, and 3 in Zhangjiakou. The Provincial Office for Energy Saving Reform will further guide the production of prefabricated components for the rational distribution of regional center cities, node cities, Beijing-Tianjin and Xiong'an regions in the province, reduce transportation costs, and increase market competitiveness.
Formulate Standards, Reduce Construction and Safety Costs
In 2015, the province promulgated five standard specifications for fabricated concrete, such as “Design Regulations for Assembled Integral Concrete Shear Walls DB13(J)/T179-2015”. Last year, the compilation and implementation of the fixed quota for fabricated concrete structural engineering in Hebei Province (on trial ), "Hebei Province's fabricated concrete structural engineering quantity list (for trial)", this year has further prepared and completed seven prefabricated concrete standards such as "trussed concrete superimposed slab" and "prefabricated shear wall structural interior wall slab". Five steel structure standards such as "Steel Structure Profile Standard" and one wood structure standard are being prepared. Among them, the “Standard for Steel Building Profiles” was prepared by the Technical Research Group composed of the architectural design and the iron and steel enterprise (Hegang Group) in order to promote the deep integration between the iron and steel industry and the construction industry, and promote the direct production of steel enterprises in line with the building model. Number of steel sections, the establishment of steel components production of "through train", reduce the amount of secondary processing, reduce the construction cost of steel structure construction costs 60 yuan -70 yuan. At the same time, the "Technical Regulations for Steel Structure Building Envelopes" was compiled to sort out the relatively mature steel structure enclosure technology and promote it.
Beijing-Tianjin-Hebei Coordinated Development Preventing New Overcapacity
According to Yu Dafei, director of the Provincial Office for Wall Materials Innovation and Building Energy Management, and director of the Provincial Building Industry Modernization Promotion Center, it is necessary to promote coordinated development of assembly buildings in the Beijing-Tianjin-Hebei region and strengthen communication and consultation. He suggested that Beijing, Tianjin and Hebei should break the regional barriers and formulate unified quality standards, technical standards, acceptance standards, and evaluation standards. Hebei has a comparative advantage in land and equipment manufacturing. Beijing and Tianjin are strong in terms of technology and capital. It is hoped that the three cities will complement each other through the construction of parks and bases. In the process of advancing the construction of prefabricated buildings, the industrial structure of the three places will inevitably overlap. The three places must focus on each other and seek for differentiated development. All localities can roughly determine the amount of project construction according to the construction land use plan and deploy it in a timely manner in order to coordinate the distribution of bases and prevent the formation of new overcapacity and waste of resources.
Yu Dafei suggested that on the basis of consensus, a framework agreement be signed by the Beijing Municipal Construction Commission, the Tianjin Construction Commission and the Hebei Housing and Urban-Rural Development Department to form a joint effort to jointly promote the booming of prefabricated buildings in the Beijing-Tianjin-Hebei region.
