Recently, the Ministry of Housing and Urban-Rural Development announced the first list of assembly-type building demonstration cities and industrial bases. 30 cities, including Tianjin, were recognized as the first demonstration buildings for assembly-type construction, Tianjin Dayin Building Materials Co., Ltd., Tianjin University Tianjin Construction Engineering Group Co., Ltd., Tianjin Housing Construction and Development Group Co., Ltd. and China Metallurgical Tiangong Group Co., Ltd. were selected into the first batch of assembly-type construction industry bases.
The wallboard, beams, stairs and other components in advance made in the factory, and then transported to the site for assembly, this "building blocks" type of building the size of the city in recent years steadily improved, land transfer or transfer of clear assembly type building The project has reached 8 million square meters, with more than 1 million square meters of prefabricated buildings under construction. The green benefits such as materials saving and consumption reduction are obvious. At present, the city has formed an annual output of 8 million square meters of construction area of ?? reinforced concrete and 6 million square meters of construction area of ?? steel construction production lines. The policy of assembly-type building development of protection, technical support and base protection is improving.
It is understood that through Shuangqing New Homeland, Heyuan, Sino-Canadian Eco-city and other projects, the Municipality has successively piloted the construction of prefabricated assemblies at rates of 30%, 45%, 65% and 80% and realized the construction of reinforced concrete structures, steel Structure, wood structure and steel modules and other structural forms of the full coverage, and is from the pilot to the city to promote.
