Steel Structure Housing Technology And Economic Analysis

1990s last stages, our country steel and iron output large growth, have provided the sufficient raw material reserve for the structural steel, one kind of new housing construction system - - steel structure system housing starts in our country to obtain the more and more widespread value and the development research. At present, entered the comprehensive unloading phase to this system research, on the one hand each place architecture industry participates in this new system positively the research and the practice, and had one batch of steel structure housing experiment site and the demonstration construction experience and the scientific and technical payoffs; On the other hand, had also discovered in the construction practice massively urgently awaits the technical question which is solved.The present paper by the steel structure housing took the object of study, the utilization classifies the research technique which and contrasts to this system to conduct the comprehensive technical efficiency research.(1) from factory angles and so on assembly degree, construction organization and efficiency, with steel quantity, applicable scope, building construction cost embarks, to the steel structure housing with the steel type, the housing system shaping, the wall material and the fire protection, the structure node and so on carries on the synthesis to compare and to analyze, in order to act according to the actual situation, chooses according to qualification.(2) from the material choice, the superiority which has carries on the synthesis comparison to the steel structure system, and from the construction cost, aspects and so on synthesis economic efficiency has carried on the technology and the efficient analysis to the steel structure housing draws the conclusion:The steel structure housing use area ratio reinforced concrete housing increases about 6%, the time limit for a project reduced large scale, has met the great span construction need, specially the superior anti-knocking property, the recoverability, has manifested the steel structure comprehensive construction cost superiority; The steel structure or the steel - concrete composite structure housing direct economic efficiency mainly comes from the structure construction time limit for a project to reduce with the house useable area rate enhancement superiority, and increases along with the housing layer, the benefit increases obviously.(3) article has quoted several project example real effective technical parameter, carries on the multianalysis to the steel structure housing economic efficiency, fairly reflected comprehensively between the steel structure housing and the concrete structure housing difference and the superiority, and will propose the steel structure housing next development direction according to the appraisal result.
