Steel residential building design cost is restricting its development is a major reason. However, steel residential building life cycle, from the total investment consideration, the cost of steel residential buildings not unacceptable. Compared with the traditional reinforced concrete structures, steel components much smaller cross-sectional area of the space occupied, which effectively increase the housing area. Made from steel but also greatly shorten the construction period, reduce overall costs. Moreover, the steel material may also be melted down for recycling. Steel is easy to industrialization, it is easy to achieve standardization of design components and parts production factory, assembly of construction machinery; can do series development, intensive production, socialization supply; but also improve efficiency, ensure quality.
Steel residential construction is designed to steel as the main structure of the building, usually a variety of building components made of steel and steel plate made of steel, such as steel beams, steel columns, steel truss, and the use of welds, bolts or rivets connection, each of the components assembled into a complete structural system, which together with energy-saving light wallboard or new materials such as brick walls built from the periphery. Along with the socio-economic reform and opening up and rapid development, China's steel production has achieved a qualitative leap, is writing a new historical period residential building legend.
Steel Structure Residential Building Technology Development, to promote the development of reform and steel construction steel industry, stimulating domestic economy. These advantages combined with the development of thermal insulation, waste utilization of new wall building materials, fully able to meet the requirements of "energy province," and green buildings. Clay is disabled in the case of steel and residential construction standards specification is complete, the development of steel structure residential building design system is feasible and necessary, and has broad prospects for development.
Energy saving: full use of solar energy, using energy-efficient building envelope and the heating and air conditioning to reduce the use of heating and air conditioning. Setting air cooling system according to the principles of natural ventilation, make the building can be effectively used in summer the prevailing wind direction. Building is adapted to local climatic conditions and the overall layout of a planar form.
Conservation of resources: in the choice of building design, construction and building materials, and are considered fair use and disposal of resources. To reduce the use of resources, and strive to make use of renewable resources. Conservation of water resources, including water conservation green.
Back to Nature: green building and the surrounding environment external to emphasize integration, harmony, complementary movement, so that the protection of the natural environment.
Comfortable and healthy living environment: inside the building without the use of harmful materials and decoration materials. Indoor air fresh, temperature and humidity appropriate to make the occupants feel good health.
Features include the construction of green building: building geographical conditions have specific requirements, the soil does not exist in toxic and hazardous substances, geothermal suitable, clean groundwater, geomagnetism moderate.
Green building should be made of natural materials. Buildings used wood, bark, bamboo, stone, lime, paint, etc., to go through the inspection process to ensure that harmful to humans.
Green building also according to geographical conditions, the solar heating, hot water, power generation and wind power generation device, in order to take full advantage of the natural environment to provide renewable energy.
With the global climate warming, the world paid more attention to energy efficiency in buildings is increasing. It is increasingly recognized that the use of building energy produced CO2 is the main contributor of climate warming. Energy-saving building construction has become an inevitable trend of development, green buildings have emerged.
