The Reuse System for Steel Structure having Construction Method of Removability and adapted Construction Market Situation

钢结构建筑构件的再利用在再生阶段只给全球环境带来很小的负荷，有效地促进了建筑垃圾的回收利用。在建筑构件的再利用系统中，有必要对其设计和生产方法进行研究。本研究从可拆卸性和可拆卸性的角度出发，明确了建筑构件的材料性能和有效的再利用连接系统，以及建筑构件流通中心收集和流通的条件。此外，还对建筑构件的再利用系统进行了建模，给出了系统运行的条件和问题。并对转换钢结构建筑构件再利用的实际情况进行了调查，找出了在设计、施工、解构和转换阶段存在的问题。

The reusing of steel building components gives the global environment only a small load at the reproduction stage is effective to promote the recycling of the construction waste. It is necessary to examine the design and the production method in the reuse system of the building element. In this research from the view point of the demountability and removability, the material performance and the effective joint system for reusing of the building element, and the condition of the circulation center to collect and circulate of the building element were clarified. In addition, the reusing system of the building element was modeled, and the condition and the problem to operate the system were presented. Furthermore, the actual conditions of reusing of building elements in the transferred steel building were investigated, the problems in design, construction, deconstruction and transfer stage were found out.
