With the rapid development of the national economy, the continuous improvement of energy saving and environmental protection requirements, the shortage of construction workers, will promote the development of steel structure housing. But the steel structure residence is a comprehensive project, which involves a very wide range. As a new thing, we need to know more about it. A number of years later, hang Xiao steel structure may only be a branch of the steel structure residential system, we have some need to improve, development of the. The development of the entire industry needs a joint effort of people of insight. Li Wenbin introduction, the current steel structure and the following aspects of the need to optimize the:
Application of the steel plate shear wall
The layout of residential buildings and the characteristics of the facade, which determines the structural system limitations. In the selection of the structural system, in addition to meet the structural requirements and architectural features, but also consider the construction conditions and project cost. At present, we mainly adopt the steel frame concrete tube body system and steel frame support system. We find that the steel plate shear wall in the residential adaptability may be stronger, we are in the relevant technology research.
Two, seeking to reduce the direct cost of the way
As for more cost-effective wall filler CCA board grouting wall grouting material using EPS concrete, which has low thermal conductivity, low weight, and so on, but higher prices of EPS, we are studying EPS concrete alternatives, the grouting material in maintaining the performance of EPS concrete, the cost will be greatly reduced.
Three, the perfection of the housing system
At present, our housing system mainly involves the construction of the main structure and the structure of the retaining structure, the relative content of the equipment is not high. This is mainly because of small differences in steel structure residential and general residential concrete technology of the facility, but from the point of view of long-term development, explore the most suitable for steel structure with supporting system is to do the work.
Four, the standardization of steel structure and the promotion of social
Steel structure residential to be recognized by the whole society, the standardization is the key. We hope that through the development and practice of the steel structure of the steel structure, the development of the whole industry, the formation of large-scale production of the whole society.
