Actively Promote Steel Structure Buildings
Steel structure building refers to a building in which section steel and steel members are connected to form the main structure of the building by welding, rivets or bolts on site, and various light building materials are used as enclosure systems.
Actively and steadily promoting steel structure buildings and advocating the development of modern wood structure buildings where conditions permit are of great significance for saving resources and energy, reducing pollution and carbon emissions, improving the seismic performance of buildings, promoting the modernization of the construction industry and the development of the forest industry, and resolving excess steel production capacity.
Advantages of Steel Structure Architecture:
1. Save materials and protect the environment. Compared with the reinforced concrete structure, the steel structure column has a small cross section, the wall thickness is reduced, the service area can be increased by 5%-8%, and the land utilization rate is correspondingly improved. Steel structure buildings and components can be manufactured in factories and assembled on site, with less wet operation on site, less construction noise and low emission of pollutants and carbon, which is beneficial to urban environmental management and environmental protection and can effectively reduce the emission of construction waste.
2. Rapid construction. As a system integration building for factory production and on-site assembly construction, steel structure construction has the advantages of short construction period, early return on investment, high utilization rate of funds, and effective improvement of project quality and management level.
3. Good seismic performance. Steel has good strength and ductility. Under the action of earthquake, steel structure can not only weaken the damage energy, but also has the deformation ability to resist strong earthquake. Steel structures have light deadweight. Compared with reinforced concrete structures, the deadweight ratio of the two types of structures is 1: 3, and the total gravity load ratio is about 1: 2. In particular, the steel structure connected by high-strength bolts can effectively resist natural disasters such as snow, wind and earthquake.
4. Materials can be recycled. Steel structure can realize the goal of storing steel in buildings and reserving resources. The recovery rate of steel structure buildings is 30% ~ 50% higher than that of reinforced concrete, and it is simple and feasible. Research data show that the steel scrap recovery rate of bridge steel structure can reach more than 98%, and that of public buildings and residential buildings is 90% ~ 95%.
5. Promote the transformation and upgrading of traditional industries. The promotion of steel structure buildings can promote the development of supporting green building industry chain enterprises and the continuous optimization of industrial structure. While stimulating consumption in the steel market, we will also promote the transformation and upgrading of construction plate, doors and windows, building materials, parts and other industries to achieve close cooperation and common development of industrial chain enterprises.
6. Cultivate and form a new industrial workforce. Promote steel structure construction, processing and production of components and fittings in factories, and train the original on-site workers to become skilled industrial workers through on-the-job skills training. Meeting the employment needs of a new generation of migrant workers after entering the city is conducive to solving social employment and promoting social stability.
7. Effectively resolve excess steel production capacity. The promotion of steel structures in the fields of housing construction, roads, railways and urban municipal bridges will have an important impact on resolving the contradiction of steel overcapacity and realizing effective market consumption.
