随着改革开放的不断深入,人民的生活水平和居住条件得到了明显的改善。我国是一个人口众多的大国,根据我国的国情,要大量征地新建或拆除旧房重建较多的住宅,是很困难的。贵阳钢厂位于市区边缘,若用征地新建或拆除旧房重建住宅来满足近万名职工急待解决的居住问题,确实困难重重。为此,贵阳钢厂经与设计和施工单位共同研究后,决定采用外包框架梁柱的结构形式,将原住宅从4层增加到9层(图1、2)。加层部分按排架结构设计。施工中柱基是关键。因柱基采用人工挖孔桩,距原建筑较近,为了不使原建筑基
With the deepening of reform and opening up, people’s living standards and living conditions have been significantly improved. China is a large country with a large population. According to our national conditions, it is very difficult to requisition a large number of land for new construction or demolish old houses to rebuild more houses. Guiyang Steel Plant is located on the edge of the urban area. It is indeed a difficult task to solve the residential problems that nearly 10,000 employees have to solve in order to rebuild new houses or demolish old houses and rebuild houses. For this reason, after a joint study with design and construction units, the Guiyang Steel Plant decided to use the structural form of the outsourcing frame beam column to increase the original dwelling from 4 to 9 floors (Figures 1 and 2). The layer-adding part is designed according to the structure of the rack. The plinth is the key to construction. Due to the use of manual digging piles for the column base, it is close to the original building, in order not to make the original building base.
