Guangzhou Steel News: Hunan introduction of three prefabricated steel construction integrated build local standards
Like making cars, like building a house, spacers, motherboard, and other components of the staircase in the workshop is completed, the workers at the site as long as the "building blocks" as these components assembled into a residence, which is the construction of the industrial development of the blue ocean. Build product technology standard system and quality control system, it is the lifeblood of the industry. Yesterday, the provincial government held a press conference in Hunan local standards, the first in the country to launch three Fabricated steel construction products and technical specification of standards for the construction of new industrialization in Hunan Province, home industrial development provided a quality guarantee.
"Fabricated steel structure construction is the direction of the residence of industrial development, the technology is very mature in a foreign country, in the country only started now choose this way of construction project in Hunan Province have offices, hotels, apartments, affordable housing, etc., for a total of more than 850 million square meters. With excess steel production capacity, reducing the cost of steel, such construction will gradually expand from public construction to civil construction, while engaged in this behavior of enterprises, as long as five, as long as the one in Hunan. "Prefabricated SERIES Standard Steel Tan Yongqiang, said one of the drafters.
To build a house like "building block" as how safety and quality assurance? The key is to achieve standardization of component parts, and the compatibility of the different plans of their products, "the three criteria is an organic whole, form a complete standard system, steel structure production to fill the gaps." Hunan Quality Jiang Tao, deputy director of supervision bureau said. Hunan three local standards are "fabricated steel structure integrated parts board" (DB43 / T 995-2015), "fabricated steel structure integrated parts bracket" (DB43 / T 1009-2015) and "fabricated ramp Technical specification steel structure supporting node "(DBJ 43 / T 311-2015).
Guangzhou Steel, the "fabricated steel structure integrated motherboard parts" and "parts fabricated steel structure integrated bracket," the two standards to achieve integration of parts and components, in which parts of the performance parameters of the function and interface technology standardization, compatible conducive scale production as well as parts of different manufacturers. And determining a plurality of components and functions of a standard structure, water, heating, electricity, ventilation, etc., it will help build the template of combinations and quick installation, also can achieve improved construction environment, transport bottlenecks break fabricated construction radius. The technical specification standards from the planning, production, installation, testing the entire process of new industrialization prefabricated steel construction system standard, focused on solving difficult problems in planning, installation and testing, will ensure the quality of construction.
Speaking of the new construction safety, a general manager of Land Rover introduced ambitious 30-story "can be built," it is the result of China Construction ASTRI seismic test bed construction 9 degrees seismic testing. From the perspective of the construction principle, the traditional concrete structure construction is seismic, and steel structure construction is the result of an elastic system absorbing shock absorption, seismic performance stronger.
Guangzhou Steel Tips
What is a fabricated steel structure to build?
Economic component factory produced steel sections used as load-bearing skeleton, with the new lightweight, insulation, insulation, high strength material as the live class construction wall enclosing structure and composition.
Compared to traditional construction, fabricated steel structure construction which features?
Standardized planning, factory production. Most members of this structure built in the factory production. Construction site assembly installation. Short construction period, usually three or four days you can build one. Seismic performance. Because steel is elastically deformable material, it can greatly improve the safety and reliability of residence. Steel for structural, thermal insulation panels for the building envelope construction, to replace clay brick, reduce the cement, sand, stone, lime dosage, reducing the damage to the non-renewable resources. Recyclable steel, the construction and demolition of environmental pollution, the energy index up more than 50%, a green construction system.
