Development of Technologies for Residential Building Stock Reseneration by Removing Structural Walls and Beams

在1955年至1973年的大规模住房时代，日本各政府当局和公共住房公司建造了大量出租住房，以重建被战争破坏的城市，并容纳城市地区高度集中的人口。日本约40%的出租公共住宅建筑是在后一个大规模住房时代（1965 - 1973年）建造的。这些都是四、五层的钢筋混凝土建筑，其建筑框架足够坚固，可以承受几十年的使用，但其内部结构和功能系统正在恶化。此外，这些住宅单元现在太小，因为住宅单元被结构墙和梁分隔成小空间。本研究的目的是开发技术，通过拆除钢筋混凝土制成的结构墙和梁，对这些老化的住宅建筑中的住宅单元逐个进行再生。

In Japan, various government authorities and public housing corporations built a huge number of dwellings for rent to reconstruct war-damaged cities and to accommodate the high concentrations of population in urban areas in the mass-housing era between 1955 and 1973. Approximately 40% of all public residential buildings for rent in Japan were constructed in the latter mass-housing era (1965-1973). These are four- or five-story reinforced concrete buildings whose building frames are sufficiently strong to withstand several decades' more use but whose interior finishings and functional systems are deteriorating. In addition, these dwelling unit is now too small because the dwelling units are separated into small spaces by the structural walls and beams. The porpose of this research is to develop technologies for regenarating a dwelling unit one-by-one in these deteriorating residential buildings by removing structural walls and beams made of reinforced concretes.
