Europe and the average life expectancy is 80 years or more, compared with the average life expectancy of China's construction is only 30 years, less than 60% of the minimum age of the national standard. In the duplication process, China created two world first: in the consumption of the world's largest cement and steel at the same time, also produced the world's largest construction waste -- each year up to 4 million tons, the number of construction waste has accounted for 30% of the total waste to 40%. Construction waste landfill were piled up and around the city, into a "junk besieged city" of the situation, not only occupy the land, which contains a variety of harmful chemical substances, serious corrosion of surface and underground water pollution, harm is great, for human survival environment pose a threat. In addition, the construction waste also fragmented urban historical context, weakening the heritage of urban culture, the destruction of the city scene.
China Construction Metal Structure Association building steel structure committee committee of experts fanghongjiang pointed out that due to the need for manual operation of reinforced concrete structure and masonry structure construction, in the field of wet construction, construction noise, dust and serious harm to the health of workers. More important is, the reinforced concrete structure and masonry structure building materials can be recycling utilization rate is extremely low, in its life cycle to the production of construction waste pollution to the environment, the descendants adverse effects has caused the extensive concern of the domestic and foreign experts and common worry. In addition, the firing of cement with high quality ore material has been very short, the preparation of concrete gravel in many places have been very nervous. Mining sand and gravel in some areas has seriously damaged the river bed, the destruction of vegetation.
Fanghongjiang proposed, steel structure building, we should firmly establish the green building design concept: in accordance with the concept of "zero resources, zero energy consumption, zero emission, zero pollution, Zero site, zero distance", the establishment from the planning, design, construction, use to the demolition of the building life cycle development and construction of the new model, development, design, and construction of a new generation of meet the industrialization, standardization and industrialization of modern steel structure residential building products.
Compared with the traditional civil construction, steel construction with "light, fast, good, province" 4 excellent performance. Steel density and strength in the ratio of less than concrete and wood, in the same conditions, using steel structure buildings as a whole the lightest weight; steel structure housing for mechanical manufacturing, high precision, convenient installation, short construction period, is a structure of engineering structure in the industrialization of the high; steel structure construction to the environment destruction, good seismic performance and suitable for different climatic conditions and atmospheric environment; with steel structure can save foundation cost, water saving, easy to control the cost. At the same time, but also be used again to reduce construction waste.
