Summary
Sustainable buildings different parts are placed on the assembly line of the factory. According to the standard production of steel structures, doors and windows, light bulbs and other 'building parts' shipped to the factory for modular assembly, and then transport these semi-finished 'building parts' to the construction site.
Sustainable buildings can be compared to building a house like a mobile phone, and different parts are placed on the assembly line of the factory. According to the standard production of steel structures, doors and windows, light bulbs and other 'building parts' shipped to the factory for modular assembly, and then transport these semi-finished 'building parts' to the construction site, it subverts the history of the construction industry for nearly a hundred years, changed traditional architectural model.
1.10 times construction safety (100% quality assurance)
Compared with traditional buildings, steel structural components are produced by high-precision production in the early stage. The production of the products is controlled by high-tech production equipment. On-site construction is mechanized, reducing manual operation errors, ensuring better quality and safer construction. Moreover, the construction efficiency is increased by 4-5 times.
2.a larger room rate (1/3 of the building weight)
Steel structure wall surface has the comprehensive advantages of steel and concrete, fewer protruding columns, fewer wall bodies, sturdy double, and indoor area utilization rate increased by 4%-6%. The number of steel structure walls is small, which reduces the building weight by 2/3 compared with traditional buildings. The layout of indoor lightweight non-bearing walls can be changed at will and the decoration is more random.
3.short construction period (1/4 of the construction period)
Since the steel structural parts are produced according to the specifications of the factory, the construction is assembled on site and the construction is not affected by the weather. The slab adopts the assembled reinforced truss self-supporting slab, which can be constructed in multiple layers at the same time, realizes the three-dimensional cross operation, and the construction speed is faster, three layers a day, saving 3/4 of the construction period than the traditional building.
4.more earthquake resistance (9 degree seismic)
Most of the low-rise villas are sloping roofs. Therefore, the roof structure basically adopts a triangular roof truss system made of cold-formed steel members. The light steel members form a very strong after sealing the structural plates and gypsum boards." The ribbed structural system, which has a stronger ability to withstand earthquakes and resist horizontal loads, and is suitable for areas with a seismic intensity of 9 degrees or more.
5.93% of the factory (1/10 on-site work)
Workplaces are done at the factory, outdoor things are done indoors, construction simulations and site stakeouts are done by computer. 85% to 95% of the parts can be processed at the factory, which is about 60% less than the number of traditional construction sites.some products can be reused, materials can be recycled. In the future, In the future, more will be sent to the construction site, not the scattered steel, concrete, insulation board, but the pieces of wall panels, stairs and other "parts"; workers assemble these "parts" into a house in the cooperation of the machinery.
6.better insulation performance
The steel structure has light weight, high strength, good overall rigidity and strong deformation ability. The building's own weight is only one-fifth of the brick-concrete structure, which can withstand hurricanes of 70 meters per second, so that life and property can be effectively protected.
The thermal insulation material used is mainly made of glass wool, which has good thermal insulation effect. The insulation board of the outer wall effectively avoids the "cold bridge" phenomenon of the wall and achieves better insulation effect. The thermal resistance of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall of 1m thick.
7.1% of construction waste (green building)
Traditional buildings produce 200 kilograms of garbage per square meter, and a 50,000 square meter building emits about 10,000 tons of garbage. Construction waste accounts for 30%-50% of urban waste. Building materials transportation and construction dust accounts for 10-30% of urban air pollution, which consumes a lot of water and pollutes water sources. The building can be built in the factory manufacturing process, and the building is still fire-free, water-free, dust-free and tasteless. No welding, no cement, no gauze, construction waste is less than 1% of conventional buildings.
8. more environmentally friendly (green building)
Steel structure houses are dry construction, so noise pollution, dust pollution and water pollution are extremely low. The amount of sand, stone and ash is greatly reduced during construction. The materials used are mainly 100% green recycled or degraded materials. When the building is demolished, it will not cause garbage pollution.
9. better sound insulation
The sound insulation effect is an important indicator for evaluating the house. The windows installed in the light steel system are all insulated glass, with good sound insulation and sound insulation of more than 40 decibels. The wall made up of light steel keel and thermal insulation gypsum board can have high sound insulation effect. 60 decibels. Health: dry work construction, reduce the pollution caused by waste to the environment, housing steel structure materials can be 100% recycled, and other supporting materials can also be mostly recycled, in line with current environmental awareness; all materials are green building materials to meet ecological requirements, good for health.
10.durability
The light steel structure residential structure is composed of cold-formed thin-walled steel component system. The steel bone is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of corrosion of the steel plate during construction and use, and increases the service life of the light steel component. The structural life can reach 100 years.
The modernization process of China's green building industry is accelerating. Relying on industrialization pilots to promote eco-friendly, high-quality, affordable and comfortable steel structures, is becoming the main theme of new residential buildings in the future.
